Organization and Business	'
	Note 1 - Organization and Business:

	Generex Biotechnology Corporation (the Company) and its wholly-owned subsidiary Generex Pharmaceuticals, Inc. are engaged in the research and development of drug delivery systems and technology. Since its inception, the Company has devoted its efforts and resources to the development of a platform technology for the oral administration of large molecule drugs, including proteins, peptides, monoclonal antibodies, hormones and vaccines, which historically have been administered by injection, either subcutaneously or intravenously. Oral-lyn^TM the first product based on this platform technology, is in various stages of regulatory approval in different jurisdictions around the world.

	The Company’s wholly-owned subsidiary, Antigen Express, Inc. (Antigen), is engaged in research and development of technologies and immunomedicines for the treatment of malignant, infectious, autoimmune and allergic diseases. The Company’s immunomedicine products work by stimulating the immune system to either attack offending agents (i.e., cancer cells, bacteria, and viruses) or to stop attacking benign elements (i.e., self proteins and allergens). The immunomedicine products are based on two platform technologies that were discovered by an executive officer of Antigen, the Ii-Key hybrid peptides and Ii-Suppression. These technologies are expected to greatly boost immune cell responses which diagnose and treat the ailments and conditions.

	The Company is a development stage company, which has a limited history of operations and limited revenue to date. This revenue has been comprised mainly of the sale of our confectionary products, although the Company has recognized $600,000 relating to upfront license fees for the signing of license and distribution agreements for Generex Oral-lyn™. Additionally, the Company has several product candidates that are in various research or early stages of pre-clinical and clinical development. There can be no assurance that the Company will be successful in obtaining regulatory clearance for the sale of existing or any future products or that any of the Company’s products will be commercially viable.

	Going Concern	Going Concern
	The accompanying interim statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business. The Company has experienced negative cash flows from operations since inception and has an accumulated deficit of approximately $367 million and a working capital deficiency of approximately $6.6 million at October 31, 2013. The Company has funded its activities to date almost exclusively from debt and equity financings, as well as the recent sales of non-essential real estate assets in fiscal 2012, fiscal 2013 and the first quarter of fiscal 2014 (see Note 11).	The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business. The Company has experienced negative cash flows from operations since inception and has an accumulated deficit of approximately $368 million and a working capital deficiency of approximately $6.7 million at July 31, 2013. The Company has funded its activities to date almost exclusively from debt and equity financings, as well as the recent sales of non-essential real estate assets in fiscal 2012, fiscal 2013 and the beginning of fiscal 2014.

	The Company will continue to require substantial funds to continue research and development, including pre-clinical studies and clinical trials of its product candidates, and to commence sales and marketing efforts, if the U.S. Food and Drug Administration or other regulatory approvals are obtained. Management’s plans in order to meet its operating cash flow requirements include financing activities such as private placements of its common stock, preferred stock offerings, issuances of debt and convertible debt instruments. Management will be limited in the financing activities that the Company undertakes in the near future as the securities purchase agreements that the Company entered into on December 10, 2012 and June 17, 2013 with certain investors prohibit the Company from (i) issuing additional equity securities until 60 days after the effective date of a registration statement covering the resale of the common stock issuable upon exercise of the warrants and conversion of the preferred stock sold in those transactions; and (ii) issuing additional debt or equity securities with variable conversion or exercise prices until December 10, 2013 and June 17, 2014, respectively. Management is also actively pursuing financial and strategic alternatives, including strategic investments and divestitures, industry collaboration activities and strategic partners. Management has sold its non-essential real estate assets which were classified as Assets Held for Investment to augment its cash position.

	These factors raise substantial doubt regarding the Company’s ability to continue as a going concern. There are no assurances that such additional funding will be achieved and that it will succeed in its future operations. The interim statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or amounts of liabilities that might be necessary should the Company be unable to continue in existence. The Company’s inability to obtain required funding in the near future or its inability to obtain funding on favorable terms will have a material adverse effect on its operations and strategic development plan for future growth. If the Company cannot successfully raise additional capital and implement its strategic development plan, its liquidity, financial condition and business prospects will be materially and adversely affected, and the Company may have to cease operations.

Summary of Significant Accounting Policies	12 Months Ended

Accounting Policies [Abstract]	'
Summary of Significant Accounting Policies	'
	Note 2 - Summary of Significant Accounting Policies:

	Principles of Consolidation
	The consolidated financial statements include the accounts of the Company and all of its subsidiaries in which a controlling interest is maintained. For those consolidated subsidiaries where the Company ownership is less than 100 percent, the outside stockholders’ interests are shown as minority interests. Effective December 17, 2004, the Company’s ownership in all consolidated subsidiaries is 100 percent. All significant intercompany transactions and balances have been eliminated.

	Development Stage Company
	The accompanying consolidated financial statements have been prepared in accordance with the provisions of FASB ASC Topic 915, “Development Stage Entities.”

	Cash and Cash Equivalents
	The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents.

	Property and Equipment
	Property and equipment are recorded at cost less accumulated depreciation. Depreciation is provided on the straight-line method over the estimated useful lives of the assets, which range from three to thirty years. Gains and losses on depreciable assets retired or sold are recognized in the statement of operations in the year of disposal. Repairs and maintenance expenditures are expensed as incurred.

	Assets Held for Investment
	Property held for investment is recorded at cost less accumulated depreciation. Depreciation is provided on the straight-line method over the estimated useful lives of the assets of thirty years. Gains and losses on depreciable assets retired or sold are recognized in the statement of operations in the year of disposal. Repairs and maintenance expenditures are expensed as incurred.

	Patents
	Capitalized patent costs represent legal costs incurred to establish patents and a portion of the acquisition price paid attributed to patents upon the acquisition of Antigen in August 2003. When patents reach a mature stage, any associated legal costs are comprised mostly of maintenance fees and costs of national applications and are expensed as incurred. Capitalized patent costs are amortized on a straight line basis over the remaining life of the patent. As patents are abandoned, the net book value of the patent is written off. In the fiscal year ended July 31, 2012, the Company recorded a write down of $440,780 on certain patents. There were no write downs or disposals in the fiscal years ended July 31, 2013 or 2011.

	Impairment or Disposal of Long-Lived Assets and Intangibles
	The Company assesses the impairment of long-lived assets under FASB ASC Topic 360 whenever events or changes in circumstances indicate that the carrying value may not be recoverable. For long-lived assets to be held and used, the Company recognizes an impairment loss only if its carrying amount is not recoverable and exceeds its fair value. The carrying amount of the long-lived asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposal of the asset. There were no write downs or disposals in the fiscal year ended July 31, 2013. In the fiscal year ended July 31, 2012, the Company sold, wrote off or disposed of certain long-lived assets with a net book value of $2,945,079. In the fiscal year ended July 31, 2011, the Company recorded a write down of $35,878 on certain equipment.

	Derivative Warrant Liability
	The Company’s derivative warrant instruments are measured at fair value using the binomial valuation model which takes into account, as of the valuation date, factors including the current exercise price, the expected life of the warrant, the current price of the underlying stock and its expected volatility, expected dividends on the stock and the risk-free interest rate for the term of the warrant. The liability is revalued at each reporting period and changes in fair value are recognized in the consolidated statements of operations under the caption “Change in fair value of derivative warrant liability.” See Note 10 – Derivative Liabilities.

	Revenue Recognition and Deferred Revenue
	Revenues from the sale of commercial products are recognized at the time title of goods passes to the buyer and the buyer assumes the risks and rewards of ownership. Certain product sales are made to retailers under agreements allowing for a right to return unsold products. In accordance with FASB ASC Topic 605, recognition of revenue on all sales to these retailers is deferred until the right of return expires, the product is sold to a third party or a provision for returns can be reasonably estimated based on historical experience. The cost of inventory under these sales is considered to be consigned inventory until the revenue is recognized. Sales are reported net of estimated returns and allowances, discounts, mail-in rebate redemptions and credit card chargebacks. If actual sales returns, allowances, discounts, mail-in rebate redemptions or credit card chargebacks are greater than estimated by management, additional expense may be incurred. At July 31, 2013, we have $224,843 of deferred revenue for which a provision for returns cannot be reasonably estimated and thus the balance is included in Deferred Revenue on our consolidated balance sheets. The corresponding cost of sales has been previously written off and is not included in inventory as of July 31, 2013 as the timing of the recognition of the revenue cannot be reasonably estimated.

	Grant revenue is recognized as the Company provides the services stipulated in the underlying grant based on the time and expenditures incurred. Amounts received in advance of services provided are recorded as deferred revenue and amortized as revenue when the services are provided. The Company received grant revenue of $488,959 in the fiscal year ended July 31, 2011 and recognized the full amount of the grant in fiscal 2011, as the Company had already incurred all of the qualifying expenses and the amount was fully received. There was no grant revenue in fiscal 2013 or 2012. See Note 13 - Qualifying Therapeutic Discovery Project Program.

	Included in miscellaneous income are fees received under licensing agreements. Nonrefundable fees received under licensing agreements are recognized as revenue when received if the Company has no continuing obligations to the other party.

	Rental income is recognized as revenue in the period in which the related rental space is occupied.

	Research and Development Costs
	Expenditures for research and development are expensed as incurred and include, among other costs, those related to the production of experimental drugs, including payroll costs, and amounts incurred for conducting clinical trials. Amounts expected to be received from governments under research and development tax credit arrangements are offset against current research and development expense.

	Income Taxes
	Income taxes are accounted for under the asset and liability method prescribed by FASB ASC Topic 740. These standards require a company to determine whether it is more likely than not that a tax position will be sustained upon examination based upon the technical merits of the position. If the more likely than not threshold is met, a company must measure the tax position to determine the amount to recognize in the financial statements. Deferred income taxes are recorded for temporary differences between financial statement carrying amounts and the tax basis of assets and liabilities. Deferred tax assets and liabilities reflect the tax rates expected to be in effect for the years in which the differences are expected to reverse. A valuation allowance is provided if it is more likely than not that some or all of the deferred tax asset will not be realized. At July 31, 2013 and 2012, the Company had a full valuation allowance equal to the amount of the net deferred tax asset.

	The Company adopted the FASB guidance concerning accounting for uncertainty in income taxes, which clarifies the accounting and disclosure for uncertainty in tax positions, as of August 1, 2007. The guidance requires that the Company determine whether it is more likely than not that a tax position will not be sustained upon examination by the appropriate taxing authority. If a tax position does not meet the more likely than not recognition criterion, the guidance requires that the tax position be measured at the largest amount of benefit greater than 50 percent not likely of being sustained upon ultimate settlement. Based on the Company’s evaluation, management has concluded that there are no significant uncertain tax positions requiring recognition in the consolidated financial statements.

	Stock-Based Compensation
	The Company follows FASB ASC Topic 718 which requires that new, modified and unvested share-based payment transactions with employees, such as grants of stock options and restricted stock, be recognized in the financial statements based on their fair value at the grant date and recognized as compensation expense over their vesting periods. The Company estimates the fair value of stock options as of the date of grant using the Black-Scholes option pricing model and restricted stock based on the quoted market price or the value of the services provided, whichever is more readily determinable. The Company also follows the guidance in FASB ASC Topic 505 for equity based payments to non-employees for equity instruments issued to consultants and other non-employees.

	Net Loss per Common Share
	Basic earnings per share is computed by dividing income (loss) available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share gives effect to all dilutive potential common shares outstanding during the period. The computation of diluted earnings per share does not assume conversion, exercise or contingent exercise of securities that would have an anti-dilutive effect on earnings. Refer to Note 14 for methodology for determining net loss per share.

	Comprehensive Income/(Loss)
	Other comprehensive income/(loss), which includes only foreign currency translation adjustments, is shown in the Statement of Changes in Stockholders’ Equity.

	Concentration of Credit Risk
	The Company maintains cash balances, at times, with financial institutions in excess of amounts insured by the Canada Deposit Insurance Corporation and the U.S. Federal Deposit Insurance Corporation. Management monitors the soundness of these institutions and has not experienced any collection losses with these financial institutions.

	Foreign Currency Translation
	Foreign denominated assets and liabilities of the Company are translated into U.S. dollars at the prevailing exchange rates in effect at the end of the reporting period. Income statement accounts are translated at a weighted average of exchange rates which were in effect during the period. Translation adjustments that arise from translating the foreign subsidiary’s financial statements from local currency to U.S. currency are recorded in the other comprehensive loss component of stockholders’ equity.

	Fair Value of Financial Instruments
	Fair value is defined under FASB ASC Topic 820 as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or the most advantageous market for an asset or liability in an orderly transaction between participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The standard describes a fair value hierarchy based on the levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value. The levels are as follows:

		·	Level 1 - Quoted prices in active markets for identical assets or liabilities
		·	Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or corroborated by observable market data for substantially the full term of the assets or liabilities
	·	Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the value of the assets or liabilities

The Company’s financial instruments consist of cash and cash equivalents, accounts receivable, long-term debt, accounts payable and accrued expenses, as well as derivative warrant liabilities and derivative additional investment rights. All of these items, except for the derivative warrant liabilities and derivative additional investment rights, were determined to be Level 1 fair value measurements. The carrying amounts of cash and cash equivalents, accounts receivable and accounts payable and accrued expenses approximate their respective fair values because of the short maturities of these instruments. Long-term debt balances were determined to approximate their fair value as we believe the borrowing rates reflect the prevailing market rates available for similar debt instruments.

The Company has determined its derivative warrant liability and its derivative additional investment rights liability to be Level 2 fair value measurements and has used the binomial lattice model valuation method to calculate the fair value of the derivative warrant liability and the derivative additional investment rights liability at July 31, 2013, 2012 and 2011. See Note 10 – Derivative Liabilities.

Use of Estimates
The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods.

The Company evaluates its estimates, including those related to bad debts, long lived assets (including patents) impairment valuations, debt obligations, derivatives, convertible preferred shares, long-term contracts, and contingencies and litigation, on an ongoing basis. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

Critical accounting estimates are reviewed and discussed with the audit committee of the board of directors. The Company considers an accounting estimate to be critical if it requires assumptions to be made that were uncertain at the time the estimate was made, if changes in the estimate if different estimates that could have been selected would have a material impact on our results of operations or financial condition.

Effects of Recent Accounting Pronouncements

Recently Adopted Accounting Pronouncements
In May 2011, the FASB issued further guidance on fair value measurements and disclosures which requires the categorization by level for items that are only required to be disclosed at fair value and information about transfers between Level 1 and Level 2. In addition, the update provides guidance on measuring the fair value of financial instruments managed within a portfolio and the application of premiums and discounts on fair value measurements. The guidance requires additional disclosure for Level 3 measurements regarding the sensitivity of fair value to changes in unobservable inputs and any interrelationships between those inputs. The guidance was effective for the Company’s interim period ended April 30, 2012. The adoption of this new accounting guidance did not have a material impact on the Company’s consolidated financial statements.

In June 2011, the FASB issued guidance regarding the presentation of Comprehensive Income within financial statements. The guidance was effective for the Company’s annual fiscal period ended July 31, 2013. The adoption of this new accounting guidance did not have a material impact on the Company’s consolidated financial statements.

	The Company has incurred losses since inception, which have generated net operating loss (“NOL”) carryforwards. The NOL carryforwards arise from both United States and Canadian sources. Pretax losses arising from domestic operations (United States) were $8,025,582, $8,040,033 and $15,060,207 for the years ended July 31, 2013, 2012 and 2011, respectively. Pretax losses arising from foreign operations (Canada) were $528,741, $1,450,244 and $6,615,660 for the years ended July 31, 2013, 2012 and 2011, respectively. As of July 31, 2013, the Company has NOL carryforwards in Generex Biotechnology Corporation of $201,080,721, which expire in 2018 through 2033, in Generex Pharmaceuticals Inc. of approximately $44,924,097, which expire in 2015 through 2033, and in Antigen Express, Inc. of approximately $23,362,008, which expire in 2016 through 2033. These loss carryforwards are subject to limitation due to the acquisition of Antigen and may be limited in future years due to certain structural ownership changes which have occurred over the last several years, related to the Company’s equity and convertible debenture financing transactions.

	For the years ended July 31, 2013, 2012 and 2011, the Company’s effective tax rate differs from the federal statutory rate principally due to net operating losses and other temporary differences for which no benefit was recorded. Additionally, effective for the year ended July 31, 2011, the Company has taken into account a decrease in the Canadian effective tax rate from 36.12% to 26.5% as of January 2012, which will reduce the future value (prior to valuation allowances) of the NOL carryforwards of the Canadian subsidiary.

Pending Litigation	'
	Note 6 – Pending Litigation:

	In February 2001, a former business associate of the former Vice President of Research and Development (“VP”) of the Company and an entity known as Centrum Technologies Inc. (“CTI”) commenced an action in the Ontario Superior Court of Justice against the Company and the VP seeking, among other things, damages for alleged breaches of contract and tortious acts related to a business relationship between this former associate and the VP that ceased in July 1996. The plaintiffs’ statement of claim also seeks to enjoin the use, if any, by the Company of three patents allegedly owned by CTI. The three patents are entitled Liquid Formulations for Proteinic Pharmaceuticals, Vaccine Delivery System for Immunization, Using Biodegradable Polymer Microspheres, and Controlled Releases of Drugs or Hormones in Biodegradable Polymer Microspheres. It is the Company’s position that the buccal drug delivery technologies which are the subject matter of the Company’s research, development, and commercialization efforts, including Generex Oral-lyn™ and the RapidMist™ Diabetes Management System, do not make use of, are not derivative of, do not infringe upon, and are entirely different from the intellectual property identified in the plaintiffs’ statement of claim. On July 20, 2001, the Company filed a preliminary motion to dismiss the action of CTI as a nonexistent entity or, alternatively, to stay such action on the grounds of want of authority of such entity to commence the action. The plaintiffs brought a cross motion to amend the statement of claim to substitute Centrum Biotechnologies, Inc. (“CBI”) for CTI. CBI is a corporation of which 50 percent of the shares are owned by the former business associate and the remaining 50 percent are owned by the Company. Consequently, the shareholders of CBI are in a deadlock. The court granted the Company’s motion to dismiss the action of CTI and denied the plaintiffs’ cross motion without prejudice to the former business associate to seek leave to bring a derivative action in the name of or on behalf of CBI. The former business associate subsequently filed an application with the Ontario Superior Court of Justice for an order granting him leave to file an action in the name of and on behalf of CBI against the VP and the Company. The Company opposed the application. In September 2003, the Ontario Superior Court of Justice granted the request and issued an order giving the former business associate leave to file an action in the name of and on behalf of CBI against the VP and the Company. A statement of claim was served in July 2004. The Company is not able to predict the ultimate outcome of this legal proceeding at the present time or to estimate an amount or range of potential loss, if any, from this legal proceeding.

	On May 20, 2011, Ms. Perri filed a statement of claim (subsequently amended) in the Ontario Superior Court of Justice, naming as defendants the Company and certain directors of the Company, Mr. Barratt, Ms. Masterson, Mr. McGee, and Mr. Fletcher. In this action, Ms. Perri has alleged that defendants engaged in discrimination, harassment, bad faith and infliction of mental distress in connection with the termination of her employment with the Company. Ms. Perri is seeking damages in this action in excess of $7,000,000 for, among other things, breach of contract, breach of fiduciary duty, violations of the Ontario Human Rights Code and aggravated and punitive damages. On September 20, 2011, the defendants filed a statement of defense and counterclaim, also naming Time Release Corp., Khazak Group Consulting Corp., and David Khazak, C.A. as defendants by counterclaim, and seeking damages of approximately $2.3 million in funds that the defendants allege Ms. Perri wrongly caused the Company to pay to third parties in varying amounts over several years and an accounting of certain third-party payments, plus interests and costs. The factual basis for the counterclaim involves payments made by the Company to third parties believed to be related to Ms. Perri. The Company intends to defend this action and pursue its counterclaim vigorously and is not able to predict the ultimate outcome of this legal proceeding at the present time or to estimate an amount or range of potential loss, if any, from this legal proceeding.

	On June 1, 2011, Golden Bull Estates Ltd. filed a claim (subsequently amended) in the Ontario Superior Court of Justice, naming the Company, 1097346 Ontario, Inc. and Generex Pharmaceuticals, Inc. as defendants. The plaintiff, Golden Bull Estates, is controlled by Ms. Perri. The plaintiff alleges damages in the amount of $550,000 for breach of contract, $50,000 for punitive damages, plus interest and costs. The plaintiff’s claims relate to an alleged contract between the plaintiff and the Company for property management services for certain Ontario properties owned by the Company. The Company terminated the plaintiff’s property management services in April 2011. Following the close of pleadings, the Company served a motion for summary judgment. The plaintiff responded by amending its statement of claim to include a claim to the Company’s interest in certain of its real estate holdings. The plaintiff moved for leave to issue and register a Certificate of Pending Litigation in respect of this real estate. The motion was not successful in respect of any current real estate holdings of the Company. The Company is not able to predict the ultimate outcome of this legal proceeding at the present time or to estimate an amount or range of potential loss, if any, from this legal proceeding.

	In August 2011, the estate of Antonio Perri, the late father of Ms. Perri, commenced an action against Generex Pharmaceuticals, Inc., the law firm of Brans, Lehun, Baldwin LLP and William Lehun in the Ontario Superior Court of Justice claiming that the estate is entitled to the proceeds of sale (approximately $1,730,000) received by the Company on its sale of two properties to Golden Bull Estates Ltd., a company controlled by Ms. Perri. The suit alleges that no consideration was received when the Company purchased the two properties from Antonio Perri in 1998. The Company has responded to this statement of claim and intends to defend this action vigorously. The Company is not able to predict the ultimate outcome of this legal proceeding at the present time or to estimate an amount or range of potential loss, if any, from this legal proceeding.

	In December 2011, a vendor of the Company commenced an action against the Company and its subsidiary, Generex Pharmaceuticals, Inc., in the Ontario Superior Court of Justice claiming damages for unpaid invoices including interest in the amount of $429,000, in addition to costs and further interest. The Company responded to this statement of claim and also asserted a counterclaim in the proceeding for $200,000 arising from the vendor’s breach of contract and detinue, together with interest and costs. On November 16, 2012, the parties agreed to settle this action and the Company has agreed to pay the plaintiff $125,000, following the spinout of its subsidiary Antigen, from the proceeds of any public or private financing related to Antigen subsequent to such spinout. Each party agreed to execute mutual releases to the claim and counterclaim to be held in trust by each party’s counsel until payment of the settlement amount. Following payment to the plaintiff, the parties agree that a Consent Dismissal Order without costs will be filed with the court. If the Company fails to make the payment following completion of any post-spinout financing related to Antigen or any other subsidiaries, the Plaintiffs may take out a judgment in the amount of the claim plus interest of 3% per annum and costs fixed at $25,000.

	The Company is involved in certain other legal proceedings in addition to those specifically described herein. Subject to the uncertainty inherent in all litigation, the Company does not believe at the present time that the resolution of any of these legal proceedings is likely to have a material adverse effect on the Company’s consolidated financial position, operations or cash flows.

	With respect to all litigation, as additional information concerning the estimates used by the Company becomes known, the Company reassesses its position both with respect to accrued liabilities and other potential exposures.

	On December 7, 2009, the Company entered into a long-term agreement with sanofi-aventis Deutschland GmbH (“sanofi”). Under this agreement, sanofi will manufacture and supply recombinant human insulin to the Company in the territories specified in the agreement. Through this agreement, the Company will procure recombinant human insulin crystals for use in the production of Generex Oral-lyn™.

To date, the Company has not met the minimum purchase commitments under this agreement. After December 31, 2011, sanofi may terminate the agreement due to the Company’s failure to meet such purchase commitments. Upon termination, the Company would be obligated to pay sanofi for all materials and components that it has acquired or ordered to manufacture insulin based on the Company’s forecasts or minimum purchase commitments, all related work-in-progress (at cost) and all finished insulin in inventory. To date, the Company has not provided forecasts to sanofi for the purchase of insulin and sanofi has not terminated the agreement.	Leases

		Supply Agreements and Purchase Obligations
		On December 7, 2009, the Company entered into a long-term agreement with sanofi-aventis Deutschland GmbH (“sanofi”). Under this agreement, sanofi will manufacture and supply recombinant human insulin to the Company in the territories specified in the agreement. Through this agreement, the Company will procure recombinant human insulin crystals for use in the production of Generex Oral-lyn™. The terms of the supply agreement required the Company to make certain minimum purchases of insulin from sanofi through the period ended December 31, 2011. To date, the Company has not met the minimum purchase commitments under this agreement. After December 31, 2011, sanofi may terminate the agreement due to the Company’s failure to meet such purchase commitments. Upon termination, the Company would be obligated to pay sanofi for all materials and components that it has acquired or ordered to manufacture insulin based on the Company’s forecasts or minimum purchase commitments, all related work-in-progress (at cost) and all finished insulin in inventory. To date, the Company has not provided forecasts to sanofi for the purchase of insulin and sanofi has not terminated the agreement.

		The Company has a supply agreement with Presspart Manufacturing Limited (“Presspart”), whereby the Company will purchase its entire requirements for products to use in the administration of insulin through the buccal mucosa and shall not purchase the products or any metal containers competitive to the products from any other person in exchange for an exclusive non-transferable royalty-free irrevocable license to use the products. The contract shall continue for a minimum period of four contract years from the end of the first contract year in which the total quantity of products purchased by the Company from Presspart exceeds 10,000,000 units, and thereafter, shall continue until terminated by either party by giving twelve months written notice. As of July 31, 2013, the Company has not yet completed a contract year in which the total quantity has exceeded 10,000,000 units and as such the expiration date of this contract cannot be determined.

		The Company’s subsidiary, Antigen, has a Clinical Study Agreement with the Henry Jackson Foundation (“HJF”) to provide services related to Antigen’s Phase II AE37 breast cancer trials. The agreement requires quarterly payments to HJF until October 1, 2013. The remaining required payments, after our fiscal year ended July 31, 2013 and until October 1, 2013, total approximately $226,000.

		The Company has a directors and officers insurance policy covering the period from April 28, 2013 to April 28, 2014. We are paying the policy in equal monthly installments until January 28, 2013. As of July 31, 2013, the total remaining installment payments are approximately $108,000.

		Pending Litigation
		In February 2001, a former business associate of the former Vice President of Research and Development (“VP”) of the Company and an entity known as Centrum Technologies Inc. (“CTI”) commenced an action in the Ontario Superior Court of Justice against the Company and the VP seeking, among other things, damages for alleged breaches of contract and tortious acts related to a business relationship between this former associate and the VP that ceased in July 1996. The plaintiffs’ statement of claim also seeks to enjoin the use, if any, by the Company of three patents allegedly owned by CTI. The three patents are entitled Liquid Formulations for Proteinic Pharmaceuticals, Vaccine Delivery System for Immunization, Using Biodegradable Polymer Microspheres, and Controlled Releases of Drugs or Hormones in Biodegradable Polymer Microspheres. It is the Company’s position that the buccal drug delivery technologies which are the subject matter of the Company’s research, development, and commercialization efforts, including Generex Oral-lyn™ and the RapidMist™ Diabetes Management System, do not make use of, are not derivative of, do not infringe upon, and are entirely different from the intellectual property identified in the plaintiffs’ statement of claim. On July 20, 2001, the Company filed a preliminary motion to dismiss the action of CTI as a nonexistent entity or, alternatively, to stay such action on the grounds of want of authority of such entity to commence the action. The plaintiffs brought a cross motion to amend the statement of claim to substitute Centrum Biotechnologies, Inc. (“CBI”) for CTI. CBI is a corporation of which 50 percent of the shares are owned by the former business associate and the remaining 50 percent are owned by the Company. Consequently, the shareholders of CBI are in a deadlock. The court granted the Company’s motion to dismiss the action of CTI and denied the plaintiffs’ cross motion without prejudice to the former business associate to seek leave to bring a derivative action in the name of or on behalf of CBI. The former business associate subsequently filed an application with the Ontario Superior Court of Justice for an order granting him leave to file an action in the name of and on behalf of CBI against the VP and the Company. The Company opposed the application. In September 2003, the Ontario Superior Court of Justice granted the request and issued an order giving the former business associate leave to file an action in the name of and on behalf of CBI against the VP and the Company. A statement of claim was served in July 2004. The Company is not able to predict the ultimate outcome of this legal proceeding at the present time or to estimate an amount or range of potential loss, if any, from this legal proceeding.

		On May 20, 2011, Ms. Perri filed a statement of claim (subsequently amended) in the Ontario Superior Court of Justice, naming as defendants the Company and certain directors of the Company, Mr. Barratt, Ms. Masterson, Mr. McGee, and Mr. Fletcher. In this action, Ms. Perri has alleged that defendants engaged in discrimination, harassment, bad faith and infliction of mental distress in connection with the termination of her employment with the Company. Ms. Perri is seeking damages in this action in excess of $7,000,000 for, among other things, breach of contract, breach of fiduciary duty, violations of the Ontario Human Rights Code and aggravated and punitive damages. On September 20, 2011, the defendants filed a statement of defense and counterclaim, also naming Time Release Corp., Khazak Group Consulting Corp., and David Khazak, C.A. as defendants by counterclaim, and seeking damages of approximately $2.3 million in funds that the defendants allege Ms. Perri wrongly caused the Company to pay to third parties in varying amounts over several years and an accounting of certain third-party payments, plus interests and costs. The factual basis for the counterclaim involves payments made by the Company to third parties believed to be related to Ms. Perri. The Company intends to defend this action and pursue its counterclaim vigorously and is not able to predict the ultimate outcome of this legal proceeding at the present time or to estimate an amount or range of potential loss, if any, from this legal proceeding.

		On June 1, 2011, Golden Bull Estates Ltd. filed a claim (subsequently amended) in the Ontario Superior Court of Justice, naming the Company, 1097346 Ontario, Inc. and Generex Pharmaceuticals, Inc. as defendants. The plaintiff, Golden Bull Estates, is controlled by Ms. Perri. The plaintiff alleges damages in the amount of $550,000 for breach of contract, $50,000 for punitive damages, plus interest and costs. The plaintiff’s claims relate to an alleged contract between the plaintiff and the Company for property management services for certain Ontario properties owned by the Company. The Company terminated the plaintiff’s property management services in April 2011. Following the close of pleadings, the Company served a motion for summary judgment. The plaintiff responded by amending its statement of claim to include a claim to the Company’s interest in certain of its real estate holdings. The plaintiff moved for leave to issue and register a Certificate of Pending Litigation in respect of this real estate. The motion was not successful in respect of any current real estate holdings of the Company. The Company is not able to predict the ultimate outcome of this legal proceeding at the present time or to estimate an amount or range of potential loss, if any, from this legal proceeding.

		In August 2011, the estate of Antonio Perri, the late father of Ms. Perri, commenced an action against Generex Pharmaceuticals, Inc., the law firm of Brans, Lehun, Baldwin LLP and William Lehun in the Ontario Superior Court of Justice claiming that the estate is entitled to the proceeds of sale (approximately $1,730,000) received by the Company on its sale of two properties to Golden Bull Estates Ltd., a company controlled by Ms. Perri. The suit alleges that no consideration was received when the Company purchased the two properties from Antonio Perri in 1998. The Company has responded to this statement of claim and intends to defend this action vigorously. The Company is not able to predict the ultimate outcome of this legal proceeding at the present time or to estimate an amount or range of potential loss, if any, from this legal proceeding.

		In December 2011, a vendor of the Company commenced an action against the Company and its subsidiary, Generex Pharmaceuticals, Inc., in the Ontario Superior Court of Justice claiming damages for unpaid invoices including interest in the amount of $429,000, in addition to costs and further interest. The Company responded to this statement of claim and also asserted a counterclaim in the proceeding for $200,000 arising from the vendor’s breach of contract and detinue, together with interest and costs. On November 16, 2012, the parties agreed to settle this action and the Company has agreed to pay the plaintiff $125,000, following the spinout of its subsidiary Antigen, from the proceeds of any public or private financing related to Antigen subsequent to such spinout. Each party agreed to execute mutual releases to the claim and counterclaim to be held in trust by each party’s counsel until payment of the settlement amount. Following payment to the plaintiff, the parties agree that a Consent Dismissal Order without costs will be filed with the court. If the Company fails to make the payment following completion of any post-spinout financing related to Antigen or any other subsidiaries, the Plaintiffs may take out a judgment in the amount of the claim plus interest of 3% per annum and costs fixed at $25,000.

		The Company is involved in certain other legal proceedings in addition to those specifically described herein. Subject to the uncertainty inherent in all litigation, the Company does not believe at the present time that the resolution of any of these legal proceedings is likely to have a material adverse effect on the Company’s consolidated financial position, operations or cash flows.

		With respect to all litigation, as additional information concerning the estimates used by the Company becomes known, the Company reassesses its position both with respect to accrued liabilities and other potential exposures.

		Employment Agreements
		As of July 31, 2013, the Company had an employment arrangement with its President & Chief Executive Officer, whereby the Company is required to pay an annual base salary of $475,000. The term of service for this executive extended through March 16, 2008, which term had not been formally extended as of July 31, 2013. In the event the agreement is terminated, by reason other than cause, death, voluntary retirement or disability, the Company is required to pay the employee in one lump sum twelve months base salary and the average annual bonus.

		As of July 31, 2013, the Company has two at will employment agreements with Antigen employees requiring the Company to pay an annual aggregate salary of $371,305 to the two employees. In the event any agreement is terminated by reason other than death, disability, a voluntary termination not for good reason (as defined in the agreement) or a termination for cause, the Company is required to pay the employees severance of six months’ salary, in accordance with the terms of the individual employment agreements.

Series A, B, C, D & E 9% Convertible Preferred Stock	'
	Note 9 - Series A, B, C, D & E 9% Convertible Preferred Stock :

	Series A 9% Convertible Preferred Stock
	The Company has authorized 5,500 shares of Series A 9% Convertible Preferred Stock with a stated value of one thousand ($1,000) per share. Pursuant to a securities purchase agreement dated July 8, 2011, the Company sold an aggregate of 2,575 shares of convertible preferred stock, as well as accompanying warrants to purchase 17,166,666 shares of common stocks. An aggregate of 17,166,666 shares of the Company’s common stock were issuable upon conversion of the convertible preferred stock which was issued at the initial closing. As of the end of the Company’s fiscal year 2012, all of the issued Series A 9% Convertible Preferred Stock had been converted to common stock. There were 17,166,666 shares of common stock issued upon the conversion of the Series A convertible preferred stock and 6,129,666 shares of common stock issued as “make-whole payments” on such conversions.

	Series B 9% Convertible Preferred Stock

Pursuant to a securities purchase agreement dated January 31, 2012, the Company sold an aggregate of 2,000 shares of Series B convertible preferred stock, as well as accompanying warrants to purchase 13,333,333 shares of common stocks. An aggregate of 13,333,333 shares of the Company’s common stock were issuable upon conversion of the Series B convertible preferred stock which was issued at the initial closing. On December 10, 2012, the triggering of the price protection features of the Series B convertible preferred stock resulted in a decrease of the conversion price from $0.08 to $0.03 per share and a corresponding increase in the number of common shares underlying the remaining 792 shares of Series B convertible preferred stock as of December 10, 2012 from 9,897,500 to 26,393,333. As of the end of the Company’s fiscal quarter ended January 31, 2013, all of the issued Series B 9% Convertible Preferred Stock had been converted to common stock. There were 38,520,832 shares of common stock issued upon the conversion of the Series B convertible preferred stock and 14,819,679 shares of common stock issued as “make-whole payments” on such conversions.

	Accounting for proceeds from the Series B convertible preferred stock financing

	The net cash proceeds from the Series B convertible preferred stock financing were $1,975,000. The proceeds from the financing were allocated first to the warrants that were issued in the financing and second to the make-whole payments. As the assigned fair values were greater than the net cash proceeds from the transaction, the excess was treated as a “deemed dividend” for accounting purposes and was reported on the Company’s consolidated statements of operations for the fiscal year ended July 31, 2012 under the caption “Preferred Stock Dividend”. The calculation methodologies for the fair values of the derivative warrant liability are described in Note 10 – Derivative Liabilities below. The fair values assigned to each component and the calculation of the amount of the deemed dividend are as follows:

	Accounting allocation of initial proceeds
		Net proceeds		$1,975,000
		Derivative warrant liability fair value		(1,811,746)
		Make-whole payments liability		(540,000)
		Deemed dividend		$(376, 746)

	Series C 9% Convertible Preferred Stock
	The Company has authorized 750 shares of Series C 9% Convertible Preferred Stock with a stated value of one thousand ($1,000) per share. Pursuant to a securities purchase agreement dated August 8, 2012, the Company sold an aggregate of 750 shares of Series C convertible preferred stock, as well as accompanying warrants to purchase 9,375,000 shares of common stocks. An aggregate of 9,375,000 shares of the Company’s common stock were issuable upon conversion of the Series C convertible preferred stock which was issued at the initial closing. On December 10, 2012, the triggering of the price protection features of the Series C convertible preferred stock resulted in a decrease of the conversion price from $0.08 to $0.03 per share and a corresponding increase in the number of common shares underlying the 650 shares of Series C convertible preferred stock as of December 10, 2012 from 8,125,000 to 21,666,666. As of the end of the Company’s fiscal quarter ended January 31, 2013, all of the issued Series C 9% Convertible Preferred Stock had been converted to common stock. There were 22,916,665 shares of common stock issued upon the conversion of the Series C convertible preferred stock and 6,664,863 shares of common stock issued as “make-whole payments” on such conversions.

	Accounting for proceeds from the Series C convertible preferred stock financing

	The net cash proceeds from the Series C convertible preferred stock financing were $725,000. The proceeds from the financing were allocated first to the warrants that were issued in the financing and second to the make-whole payments. As the assigned fair values were greater than the net cash proceeds from the transaction, the excess was treated as a “deemed dividend” for accounting purposes and was reported on the Company’s interim consolidated statements of operations for the quarter ended October 31, 2012 under the caption “Preferred Stock Dividend”. The calculation methodologies for the fair value of the derivative warrant liability is described in Note 10 – Derivative Liabilities below. The fair values assigned to each component and the calculation of the amount of the deemed dividend are as follows:

	Accounting allocation of initial proceeds
		Net proceeds		$725,000
		Derivative warrant liability fair value		(624,797)
		Make-whole payments liability		(202,500)
		Deemed dividend		($102,297)

	Series D 9% Convertible Preferred Stock
	The Company has authorized 750 shares of Series D 9% Convertible Preferred Stock with a stated value of one thousand ($1,000) per share. Pursuant to a securities purchase agreement dated December 10, 2012, the Company sold an aggregate of 750 shares of Series D convertible preferred stock, as well as accompanying warrants to purchase 24,999,999 shares of common stocks. An aggregate of 24,999,999 shares of the Company’s common stock are issuable upon conversion of the Series D convertible preferred stock which was issued at the initial closing. As of July 31, 2013, all of the Series D convertible preferred stock had been converted to common stock. There were 24,999,999 shares of common stock issued upon the conversion of the Series D convertible preferred stock and 7,825,191 shares of common stock issued as “make-whole payments” on such conversions.

	Accounting for proceeds from the Series D convertible preferred stock financing

	The net cash proceeds from the Series D convertible preferred stock financing were $725,000. As the Company did not have sufficient authorized capital for the issuance of the shares underlying the Series D convertible preferred stock at the time of issuance, equity treatment was not permitted under GAAP. The Series D convertible preferred stock was classified as a derivative liability on the Company’s interim consolidated balance sheet as of the previous quarter ended January 31, 2013. Due to the redemption provision in the event that an increase in the Company’s authorized capital was not approved by the stockholders, the Series D convertible preferred stock was reported at that date at its face value of $750,000. Upon the stockholder approval of the increase in authorized capital on March 28, 2013, the Series D convertible preferred stock met the criteria for equity classification and was reclassified as equity at its then face value of $750,000.

			The calculation methodologies for the fair value of the derivative warrant liability is described in Note 10 – Derivative Liabilities below.

			Series E 9% Convertible Preferred Stock
	The Company has authorized 2,450 shares of Series E 9% Convertible Preferred Stock with a stated value of one thousand ($1,000) per share. Pursuant to a securities purchase agreement dated June 17, 2013, the Company sold an aggregate of 1,225 shares of Series E convertible preferred stock, as well as accompanying warrants to purchase 40,833,335 shares of common stocks. An aggregate of 40,833,335 shares of the Company’s common stock are issuable upon conversion of the Series E convertible preferred stock which was issued at the initial closing.

	Subject to certain ownership limitations, the convertible preferred stock is convertible at the option of the holder at any time into shares of the Company’s common stock at an effective conversion price of $0.03 per share, and will accrue a 9% dividend until June 17, 2016 and, beginning on June 17, 2016 and on each one year anniversary thereafter, such dividend rate will increase by an additional 3%. The dividend is payable quarterly on September 30, December 31, March 31 and June 30, beginning on June 30, 2013 and on each conversion date in cash, or at the Company’s option, in shares of common stock. In the event that the convertible preferred stock is converted prior to June 17, 2016, the Company will pay the holder of the converted preferred stock an amount equal to $270 per $1,000 of stated value of the convertible preferred stock, less the amount of all prior quarterly dividends paid on such converted preferred stock before the relevant conversion date. Such “make-whole payment” may be made in cash or, at the Company’s option, in shares of its common stock. In addition, beginning June 17, 2016, the Company will pay dividends on shares of preferred stock equal to (on an as-if-converted-to-common-stock basis) and in the same form as dividends (other than dividends in the form of common stock) actually paid on shares of the common stock when, and if such dividends are paid. The Company will incur a late fee of 18% per annum on unpaid dividends.

	The conversion price of the convertible preferred stock is subject to adjustment in the case of stock splits, stock dividends, combinations of shares, similar recapitalization transactions and certain pro-rata distributions to common stockholders. The conversion price will also be adjusted if the Company sells or grants any shares of common stock or securities convertible into, or rights to acquire, common stock at an effective price per share that is lower than the then conversion price, except in the event of certain exempt issuances. In addition, the holders of convertible preferred stock will be entitled to receive any securities or rights to acquire securities or property granted or issued by the Company pro rata to the holders of its common stock to the same extent as if such holders had converted all of their shares of convertible preferred stock. In the event of a fundamental transaction, such as a merger, consolidation, sale of substantially all assets and similar reorganizations or recapitalizations, the holders of convertible preferred stock will be entitled to receive, upon conversion of their shares, any securities or other consideration received by the holders of the Company’s common stock pursuant to the fundamental transaction.

	The Company may become obligated to redeem the convertible preferred stock in cash upon the occurrence of certain triggering events, including the failure to provide an effective registration statement covering shares of common stock issuable upon conversion of the convertible preferred stock, material breach of certain contractual obligations to the holders of the convertible preferred stock, the occurrence of a change in control of the Company, the occurrence of certain insolvency events relating to the Company, or the failure of the Company’s common stock to continue to be listed or quoted for trading on one or more specified United States securities exchanges or regulated quotation services. Upon the occurrence of certain triggering events, each holder of convertible preferred stock will have the option to redeem such holder’s shares of convertible preferred stock for a redemption price payable in shares of common stock or receive an increased dividend rate of 18% on all of such holder’s outstanding convertible preferred stock.

	In conjunction with the issuance of the Series E convertible preferred stock, the Company also issued 40,833,335 warrants to the investors. Subject to certain ownership limitations, the warrants will be exercisable at any time after their date of issuance and on or before the fifth-year anniversary thereafter at an exercise price of $0.03 per share of common stock. The exercise price of the warrants and, in some cases, the number of shares issuable upon exercise, are subject to adjustment in the case of stock splits, stock dividends, combinations of shares, similar recapitalization transactions and certain pro-rata distributions to common stockholders. The exercise price and number of shares of common stock issuable upon exercise will also be adjusted if the Company sells or grants any shares of common stock or securities convertible into, or rights to acquire, common stock at an effective price per share that is lower than the then exercise price, except in the event of certain exempt issuances. In addition, the warrant holders will be entitled to receive any securities or rights to acquire securities or property granted or issued by the Company pro rata to the holders of its common stock to the same extent as if such holders had exercised all of their warrants. In the event of a fundamental transaction, such as a merger, consolidation, sale of substantially all assets and similar reorganizations or recapitalizations, the warrant holders will be entitled to receive, upon exercise of their warrants, any securities or other consideration received by the holders of the Company’s common stock pursuant to the fundamental transaction. These warrants have been classified as derivative liabilities and are described further in Note 10 – Derivative Liabilities.

	In addition, until the first anniversary of date of the securities purchase agreement, each investor may, in its sole determination, elect to purchase, severally and not jointly with the other investors, in one or more purchases, in the ratio of such investor's original subscription amount to the original aggregate subscription amount of all investors, additional units consisting of convertible preferred stock and warrants at a purchase price of $1,000 per unit with an aggregate subscription amount thereof of up to $1,225,000, which units will have terms identical to the units of convertible preferred stock and warrants issued in connection with the June 2013 closing. These additional investment rights of the investors have been classified as derivative liabilities and are described further in Note 10 – Derivative Liabilities.

	As of July 31, 2013, 295 of the Series E convertible preferred stock had been converted to common stock. There were 9,833,334 shares of common stock issued upon the conversion of the Series E convertible preferred stock and 2,654,999 shares of common stock issued as “make-whole payments” on such conversions.

	Accounting for proceeds from the Series E convertible preferred stock financing

	The net cash proceeds from the Series E convertible preferred stock financing were $1,165,000. The proceeds from the financing were allocated first to the warrants that were issued in the financing, second to the additional investment rights associated with the financing and third to the make whole payments. As the assigned fair values were greater than the net cash proceeds from the transaction, the excess was treated as a “deemed dividend” for accounting purposes and is reported on the Company’s consolidated statement of operations for the year ended July 31, 2013 under the caption “Preferred Stock Dividend”. The calculation methodologies for the fair values of the derivative warrant liability and the derivative additional investment rights liability are described in Note 10 – Derivative Liabilities below. The fair values assigned to each component and the calculation of the amount of the deemed dividend are as follows:

	The Company’s derivative instruments have been measured at fair value at October 31, 2013 and July 31, 2013 using the binomial lattice model. The Company recognizes all of its warrants with price protection in its consolidated balance sheets as a liability. The liability is revalued at each reporting period and changes in fair value are recognized currently in the consolidated statements of operations. The initial recognition and subsequent changes in fair value of the derivative warrant liability have no effect on the Company’s consolidated cash flows.										The Company’s derivative warrant instruments have been measured at fair value at July 31, 2013 and 2012 using the binomial lattice model. The Company recognizes all of its warrants with price protection in its consolidated balance sheets as a liability. The liability is revalued at each reporting period and changes in fair value are recognized currently in the consolidated statements of operations. The initial recognition and subsequent changes in fair value of the derivative warrant liability have no effect on the Company’s consolidated cash flows.

	The derivative warrants outstanding at October 31, 2013 are all currently exercisable with a weighted-average remaining life of 3.2 years.										The derivative warrants outstanding at July 31, 2013 are all currently exercisable with a weighted-average remaining life of 3.46 years.

	The revaluation of the warrants at ends of the respective reporting periods resulted in the recognition of a gain of $1,048,859 within the Company’s consolidated statements of operations for the three months ended October 31, 2013 and a loss of $358,714 for the three months ended October 31, 2012, which is included in the consolidated statement of operations under the caption “Change in fair value of derivative liabilities”.

	Fair Value Assumptions Used in Accounting for Derivative Warrant Liability
	The Company has determined its derivative warrant liability to be a Level 2 fair value measurement and has used the binominal lattice pricing model to calculate the fair value as of October 31, 2013 and July 31, 2013. The binomial lattice model requires six basic data inputs: the exercise or strike price, time to expiration, the risk free interest rate, the current stock price, the estimated volatility of the stock price in the future, and the dividend rate. Because the warrants contain the price protection feature, the probability that the exercise price of the warrants would decrease as the stock price decreased was incorporated into the valuation calculations. The key inputs used in the October 31, 2013 and July 31, 2013 fair value calculations were as follows:										Fair Value Assumptions Used in Accounting for Derivative Warrant Liability

In addition, the warrant holders will be entitled to receive any securities or rights to acquire securities or property granted or issued by the Company pro rata to the holders of its common stock to the same extent as if such holders had exercised all of their warrants. In the event of a fundamental transaction, such as a merger, consolidation, sale of substantially all assets and similar reorganizations or recapitalizations, the warrant holders will be entitled to receive, upon exercise of their warrants, any securities or other consideration received by the holders of the Company’s common stock pursuant to the fundamental transaction. These warrants have been classified as derivative liabilities and are described further in Note 10 – Derivative Liabilities.

In addition, until the first anniversary date of the securities purchase agreement, each investor may, in its sole determination, elect to purchase, severally and not jointly with the other investors, in one or more purchases, in the ratio of such investor's original subscription amount to the original aggregate subscription amount of all investors, additional units consisting of convertible preferred stock and warrants at a purchase price of $1,000 per unit with an aggregate subscription amount thereof of up to $1,225,000, which units will have terms identical to the units of convertible preferred stock and warrants issued in connection with the June 2013 closing. These additional investment rights of the investors have been classified as derivative liabilities and are described further in Note 10 – Derivative Liabilities.

As of October 31, 2013, 855 of the Series E convertible preferred stock had been converted to common stock. There were 28,499,999 shares of common stock issued upon the conversion of the Series E convertible preferred stock and 7,856,738 shares of common stock issued as “make-whole payments” on such conversions.

Accounting for proceeds from the Series E convertible preferred stock financing

The net cash proceeds from the Series E convertible preferred stock financing were $1,165,000. The proceeds from the financing were allocated first to the warrants that were issued in the financing, second to the additional investment rights associated with the financing and third to the make whole payments. As the assigned fair values were greater than the net cash proceeds from the transaction, the excess was treated as a “deemed dividend” for accounting purposes and was reported on the Company’s consolidated statement of operations for the year ended July 31, 2013 under the caption “Preferred Stock Dividend”. The calculation methodologies for the fair values of the derivative warrant liability and the derivative additional investment rights liability are described in Note 10 – Derivative Liabilities below. The fair values assigned to each component and the calculation of the amount of the deemed dividend are as follows:

	Accounting allocation of initial proceeds
	Net proceeds		$	1,165,000
	Derivative warrant liability fair value			(1,189,744	)
	Derivative additional investment rights fair value			(1,264,683	)
	Make whole payments liability			(330,750	)
	Deemed dividend		$	(1,620,177	)


The initial “make-whole payments” of $330,750 on the Series E convertible preferred stock were accrued as of the date of the financing and the remaining balance of $99,900 (after conversions) is included in Accounts Payable and Accrued Expenses (see Note 5) at October 31, 2013.

										As of July 31, 2013, the Company had two stockholder-approved stock incentive plans under which shares and options exercisable for shares of common stock have been or may be granted to employees, directors, consultants and advisors. A total of 12,000,000 shares of common stock are reserved for issuance under the 2001 Stock Option Plan (the 2001 Plan) and 60,000,000 shares of common stock are reserved for issuance under the 2006 Stock Plan as amended (the 2006 Plan). At July 31, 2013, there were 4,650,222 and 7,113,391 shares of common stock reserved for future awards under the 2001 Plan and 2006 Plan, respectively. The Company issues new shares of common stock from the shares reserved under the respective Plans upon conversion or exercise of options and issuance of restricted shares.
	The 2001 and 2006 Plans (the Plans) are administered by the Board of Directors (the Board). The Board is authorized to select from among eligible employees, directors, advisors and consultants those individuals to whom options are to be granted and to determine the number of shares to be subject to, and the terms and conditions of the options. The Board is also authorized to prescribe, amend and rescind terms relating to options granted under the Plans. Generally, the interpretation and construction of any provision of the Plans or any options granted hereunder is within the discretion of the Board.

Generally, the interpretation and construction of any provision of the Plans or any options granted hereunder is within the discretion of the Board.
	The Plans provide that options may or may not be Incentive Stock Options (ISOs) within the meaning of Section 422 of the Internal Revenue Code. Only employees of the Company are eligible to receive ISOs, while employees and non-employee directors, advisors and consultants are eligible to receive options which are not ISOs, i.e. “Non-Qualified Options.” The options granted by the Board in connection with its adoption of the Plans were Non-Qualified Options. In addition, the 2006 Plan also provides for restricted stock grants.

In addition, the 2006 Plan also provides for restricted stock grants.
	The fair value of each option granted is estimated on the grant date using the Black-Scholes option pricing model or the value of the services provided, whichever is more readily determinable. The Black-Scholes option pricing model takes into account, as of the grant date, the exercise price and expected life of the option, the current price of the underlying stock and its expected volatility, expected dividends on the stock and the risk-free interest rate for the term of the option.

	In the case of restricted stock grants under the 2006 Plan, fair market value of the shares is established as the market price on the date of the stock grant or the value of the services provided, whichever is more readily determinable.											Share-based employee compensation related to stock options for the years ended July 31, 2013, 2012 and 2011 amounted to $837,753, $602,384 and $936,465 for each year and were charged to the consolidated statements of operations. Share-based employee compensation related to common stock grants for the years ended July 31, 2013, 2012 and 2011 amounted to 0, $130,544 and $100,999, respectively, and were charged to the consolidated statements of operations.

	The following is a summary of the common stock options granted, forfeited or expired and exercised under the Plans for the three months ended October 31, 2013:									The fair value of each option granted is estimated on grant date using the Black-Scholes option pricing model which takes into account as of the grant date the exercise price and expected life of the option, the current price of the underlying stock and its expected volatility, expected dividends on the stock and the risk-free interest rate for the term of the option. The Black-Scholes option pricing model was not used to estimate the fair value any option grants in the fiscal years ended July 31, 2013 and 2012. The following are the variables used to calculate the fair value for the options granted in the fiscal year ended July 31, 2011:

										As of July 31, 2013, the Company had $5,365 of total unrecognized compensation cost related to non-vested share-based compensation arrangements granted under the Plan. That cost is expected to be recognized over a weighted-average period of 0.2 years.

										During the twelve months ended July 31, 2013, the Company granted 24,532,719 options to executives, employees and directors in full and final payment of obligations to pay such individuals deferred salary or director fees. The options were issued in lieu of cash payment of deferred compensation amounts due to such individuals. The number of options granted to each individual was equal to the dollar amount of deferred salary or fees due to such individual divided by the closing price of the Company's common stock on February 5, 2013 ($0.038), March 5, 2013 ($0.034) and June 4, 2013 ($0.0325). The stock options had an exercise price equal to $0.001 per share and were made pursuant to the terms of the Company's 2006 Stock Plan. The options were fully vested at the dates of the grants and expire on the fifth anniversary of the respective dates of grant. The grants were valued at the amount of deferred compensation owed to each such individual.

										During the twelve months ended July 31, 2012, the Company granted 5,851,696 options to executives, employees and directors in full and final payment of obligations to pay such individuals deferred salary or director fees. The options were issued in lieu of cash payment of deferred compensation amounts due to such individuals. The number of options granted to each individual was equal to the dollar amount of deferred salary or fees due to such individual divided by the closing price of the Company's common stock on June 6, 2012 ($0.0925). The stock options had an exercise price equal to $0.001 per share and were made pursuant to the terms of the Company's 2006 Stock Plan.

The grants were valued at the amount of deferred compensation owed to each such individual.

										During the twelve months ended July 31, 2011, the Company granted 3,300,000 options to executives, directors and management employees, as compensation. The total fair value of the options at the date of grant was $692,010. The options vested immediately and a charge of $692,010 was recorded at the date of grant. The fair value of each option granted was estimated on the grant date using the Black-Scholes option pricing model, taking into account the grant date exercise price and current price of the underlying stock of $0.282, an expected life of the option of 5 years, an expected volatility of 101.3%, expected dividends on the stock of $0 and the risk-free interest rate for the term of the option of 0.13%.

	Note 13 - Qualifying Therapeutic Discovery Project Program:

	In the Company’s fiscal year ended July 31, 2011, the Company’s wholly-owned subsidiary Antigen Express, Inc. received notification that it had been awarded a total cash grant of $488,959 under the Qualifying Therapeutic Discovery Project program administered under Section 48D of the Internal Revenue Code, all of which relates to qualifying expenses that had previously been incurred. The Company recognized the full amount of the grant in the fiscal year ended July 31, 2011, as the Company has already incurred all of the qualifying expenses and the amount has been fully received. Since this program is non-recurring in nature, the Company elected to classify this payment as other income in the consolidated statements of operations for the fiscal year ended July 31, 2011 and it is reported in the “Miscellaneous Income” line item.

		Basic loss per share (“EPS”) and Diluted EPS for the years ended July 31, 2013, 2012 and 2011 have been computed by dividing the net loss available to common stockholders for each respective period by the weighted average shares outstanding during that period. All outstanding options, warrants, non-vested restricted stock and shares to be issued upon conversion of the outstanding convertible preferred stock, representing approximately 298,931,138, 94,643,712 and 115,875,372 incremental shares, have been excluded from the respective 2013, 2012 and 2011 computation of diluted EPS as they are anti-dilutive due to the losses generated during the respective years.
	Basic earnings per share (“EPS”) for the three-month period ended October 31, 2013 has been computed by dividing the net income available to common stockholders for the period by the weighted average shares outstanding during that period.

	Diluted EPS for the three-month period ended October 31, 2013 has been computed by dividing the net income available to common stockholders payments for the period ($530,094), as adjusted downwards by the remaining “make-whole payments on the outstanding convertible preferred stock ($99,900) (see Note 5), by the diluted weighted average shares outstanding during that period. Per the treasury method of calculating Diluted EPS, 32,308,428 shares representing outstanding stock options and 18,410,183 shares representing outstanding warrants which have an exercise price lower than the average market price for the quarter ended October 31, 2013, are included in the calculation of EPS. In addition, 15,663,334 shares underlying the remaining Series E convertible preferred stock (including 3,330,000 shares for “make-whole payments”) have been added to the number of shares used in the Diluted EPS calculation. All remaining outstanding stock options and warrants which have out-of-the-money exercise prices, representing 22,797,402 incremental shares in aggregate, have been excluded from the October 31, 2013 computation of Diluted EPS, as they are anti-dilutive.

	Basic EPS and Diluted EPS for the three-month period ended October 31, 2012 have been computed by dividing the net loss available to common stockholders for the period by the weighted average shares outstanding during that period. All outstanding stock options, non-vested restricted stock, warrants and common stock underlying convertible preferred stock, representing 162,146,167 incremental shares at October 31, 2012, have been excluded from the computation of Diluted EPS as they are anti-dilutive, due to the loss generated during that period.

	The Company follows FASB ASC Topic 815 which establishes standards for the way that public business enterprises report information about operating segments in annual financial statements and requires that those enterprises report selected information about operating segments in interim financial reports. This Topic also establishes standards for related disclosures about products and services, geographic areas, and major customers.

	This Topic uses a management approach for determining segments. The management approach designates the internal organization that is used by management for making operating decisions and assessing performance as the source of the Company’s reportable segments. The Company’s management reporting structure provides for only one segment: the research, development and commercialization of drug delivery systems and technologies for metabolic and immunological diseases.

Summary of Significant Accounting Policies (Policies)	3 Months Ended	12 Months Ended
	Oct. 31, 2013	Jul. 31, 2013
Accounting Policies [Abstract]	'	'
Principles of Consolidation	'	'
		Principles of Consolidation
		The consolidated financial statements include the accounts of the Company and all of its subsidiaries in which a controlling interest is maintained. For those consolidated subsidiaries where the Company ownership is less than 100 percent, the outside stockholders’ interests are shown as minority interests. Effective December 17, 2004, the Company’s ownership in all consolidated subsidiaries is 100 percent. All significant intercompany transactions and balances have been eliminated.
Development Stage Company	'	'
		Development Stage Company
		The accompanying consolidated financial statements have been prepared in accordance with the provisions of FASB ASC Topic 915, “Development Stage Entities.”
Cash and Cash Equivalents	'	'
		Cash and Cash Equivalents
		The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents.
Property and Equipment	'	'
		Property and Equipment
		Property and equipment are recorded at cost less accumulated depreciation. Depreciation is provided on the straight-line method over the estimated useful lives of the assets, which range from three to thirty years. Gains and losses on depreciable assets retired or sold are recognized in the statement of operations in the year of disposal. Repairs and maintenance expenditures are expensed as incurred.
Assets Held for Investment	'	'
		Assets Held for Investment
		Property held for investment is recorded at cost less accumulated depreciation. Depreciation is provided on the straight-line method over the estimated useful lives of the assets of thirty years. Gains and losses on depreciable assets retired or sold are recognized in the statement of operations in the year of disposal. Repairs and maintenance expenditures are expensed as incurred.
Patents	'	'
		Patents
		Capitalized patent costs represent legal costs incurred to establish patents and a portion of the acquisition price paid attributed to patents upon the acquisition of Antigen in August 2003. When patents reach a mature stage, any associated legal costs are comprised mostly of maintenance fees and costs of national applications and are expensed as incurred. Capitalized patent costs are amortized on a straight line basis over the remaining life of the patent. As patents are abandoned, the net book value of the patent is written off. In the fiscal year ended July 31, 2012, the Company recorded a write down of $440,780 on certain patents. There were no write downs or disposals in the fiscal years ended July 31, 2013 or 2011.
Impairment or Disposal of Long-Lived Assets and Intangibles	'	'
		Impairment or Disposal of Long-Lived Assets and Intangibles
		The Company assesses the impairment of long-lived assets under FASB ASC Topic 360 whenever events or changes in circumstances indicate that the carrying value may not be recoverable. For long-lived assets to be held and used, the Company recognizes an impairment loss only if its carrying amount is not recoverable and exceeds its fair value. The carrying amount of the long-lived asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposal of the asset. There were no write downs or disposals in the fiscal year ended July 31, 2013. In the fiscal year ended July 31, 2012, the Company sold, wrote off or disposed of certain long-lived assets with a net book value of $2,945,079. In the fiscal year ended July 31, 2011, the Company recorded a write down of $35,878 on certain equipment.
Derivative Warrant Liability	'	'
		Derivative Warrant Liability
		The Company’s derivative warrant instruments are measured at fair value using the binomial valuation model which takes into account, as of the valuation date, factors including the current exercise price, the expected life of the warrant, the current price of the underlying stock and its expected volatility, expected dividends on the stock and the risk-free interest rate for the term of the warrant. The liability is revalued at each reporting period and changes in fair value are recognized in the consolidated statements of operations under the caption “Change in fair value of derivative warrant liability.” See Note 10 – Derivative Liabilities.
Revenue Recognition and Deferred Revenue	'	'
		Revenue Recognition and Deferred Revenue
		Revenues from the sale of commercial products are recognized at the time title of goods passes to the buyer and the buyer assumes the risks and rewards of ownership. Certain product sales are made to retailers under agreements allowing for a right to return unsold products. In accordance with FASB ASC Topic 605, recognition of revenue on all sales to these retailers is deferred until the right of return expires, the product is sold to a third party or a provision for returns can be reasonably estimated based on historical experience. The cost of inventory under these sales is considered to be consigned inventory until the revenue is recognized. Sales are reported net of estimated returns and allowances, discounts, mail-in rebate redemptions and credit card chargebacks. If actual sales returns, allowances, discounts, mail-in rebate redemptions or credit card chargebacks are greater than estimated by management, additional expense may be incurred. At July 31, 2013, we have $224,843 of deferred revenue for which a provision for returns cannot be reasonably estimated and thus the balance is included in Deferred Revenue on our consolidated balance sheets. The corresponding cost of sales has been previously written off and is not included in inventory as of July 31, 2013 as the timing of the recognition of the revenue cannot be reasonably estimated.

		Grant revenue is recognized as the Company provides the services stipulated in the underlying grant based on the time and expenditures incurred. Amounts received in advance of services provided are recorded as deferred revenue and amortized as revenue when the services are provided. The Company received grant revenue of $488,959 in the fiscal year ended July 31, 2011 and recognized the full amount of the grant in fiscal 2011, as the Company had already incurred all of the qualifying expenses and the amount was fully received. There was no grant revenue in fiscal 2013 or 2012. See Note 13 - Qualifying Therapeutic Discovery Project Program.

		Included in miscellaneous income are fees received under licensing agreements. Nonrefundable fees received under licensing agreements are recognized as revenue when received if the Company has no continuing obligations to the other party.

		Rental income is recognized as revenue in the period in which the related rental space is occupied.
Research and Development Costs	'	'
		Research and Development Costs
		Expenditures for research and development are expensed as incurred and include, among other costs, those related to the production of experimental drugs, including payroll costs, and amounts incurred for conducting clinical trials. Amounts expected to be received from governments under research and development tax credit arrangements are offset against current research and development expense.
Income Taxes	'	'
		Income Taxes
		Income taxes are accounted for under the asset and liability method prescribed by FASB ASC Topic 740. These standards require a company to determine whether it is more likely than not that a tax position will be sustained upon examination based upon the technical merits of the position. If the more likely than not threshold is met, a company must measure the tax position to determine the amount to recognize in the financial statements. Deferred income taxes are recorded for temporary differences between financial statement carrying amounts and the tax basis of assets and liabilities. Deferred tax assets and liabilities reflect the tax rates expected to be in effect for the years in which the differences are expected to reverse. A valuation allowance is provided if it is more likely than not that some or all of the deferred tax asset will not be realized. At July 31, 2013 and 2012, the Company had a full valuation allowance equal to the amount of the net deferred tax asset.

		The Company adopted the FASB guidance concerning accounting for uncertainty in income taxes, which clarifies the accounting and disclosure for uncertainty in tax positions, as of August 1, 2007. The guidance requires that the Company determine whether it is more likely than not that a tax position will not be sustained upon examination by the appropriate taxing authority. If a tax position does not meet the more likely than not recognition criterion, the guidance requires that the tax position be measured at the largest amount of benefit greater than 50 percent not likely of being sustained upon ultimate settlement. Based on the Company’s evaluation, management has concluded that there are no significant uncertain tax positions requiring recognition in the consolidated financial statements.
Stock-Based Compensation	'	'
		Stock-Based Compensation
		The Company follows FASB ASC Topic 718 which requires that new, modified and unvested share-based payment transactions with employees, such as grants of stock options and restricted stock, be recognized in the financial statements based on their fair value at the grant date and recognized as compensation expense over their vesting periods. The Company estimates the fair value of stock options as of the date of grant using the Black-Scholes option pricing model and restricted stock based on the quoted market price or the value of the services provided, whichever is more readily determinable. The Company also follows the guidance in FASB ASC Topic 505 for equity based payments to non-employees for equity instruments issued to consultants and other non-employees.
Net Loss per Common Share	'	'
		Net Loss per Common Share
		Basic earnings per share is computed by dividing income (loss) available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share gives effect to all dilutive potential common shares outstanding during the period. The computation of diluted earnings per share does not assume conversion, exercise or contingent exercise of securities that would have an anti-dilutive effect on earnings. Refer to Note 14 for methodology for determining net loss per share.
Comprehensive Income/(Loss)	'	'
	Note 4 – Comprehensive Income and Loss:	Comprehensive Income/(Loss)
		Other comprehensive income/(loss), which includes only foreign currency translation adjustments, is shown in the Statement of Changes in Stockholders’ Equity.
	Comprehensive income, which includes net income and the change in the foreign currency translation account, was $531,771 for the three months ended October 31, 2013. Comprehensive loss, which includes net loss and the change in the foreign currency translation account, was $668,679 for the three months ended October 31, 2012.
Concentration of Credit Risk	'	'
		Concentration of Credit Risk
		The Company maintains cash balances, at times, with financial institutions in excess of amounts insured by the Canada Deposit Insurance Corporation and the U.S. Federal Deposit Insurance Corporation. Management monitors the soundness of these institutions and has not experienced any collection losses with these financial institutions.
Foreign Currency Translation	'	'
		Foreign Currency Translation
		Foreign denominated assets and liabilities of the Company are translated into U.S. dollars at the prevailing exchange rates in effect at the end of the reporting period. Income statement accounts are translated at a weighted average of exchange rates which were in effect during the period. Translation adjustments that arise from translating the foreign subsidiary’s financial statements from local currency to U.S. currency are recorded in the other comprehensive loss component of stockholders’ equity.
Fair Value of Financial Instruments	'	'
		Fair Value of Financial Instruments
		Fair value is defined under FASB ASC Topic 820 as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or the most advantageous market for an asset or liability in an orderly transaction between participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The standard describes a fair value hierarchy based on the levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value. The levels are as follows:

			·	Level 1 - Quoted prices in active markets for identical assets or liabilities
			·	Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or corroborated by observable market data for substantially the full term of the assets or liabilities
			·	Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the value of the assets or liabilities

		The Company’s financial instruments consist of cash and cash equivalents, accounts receivable, long-term debt, accounts payable and accrued expenses, as well as derivative warrant liabilities and derivative additional investment rights. All of these items, except for the derivative warrant liabilities and derivative additional investment rights, were determined to be Level 1 fair value measurements. The carrying amounts of cash and cash equivalents, accounts receivable and accounts payable and accrued expenses approximate their respective fair values because of the short maturities of these instruments. Long-term debt balances were determined to approximate their fair value as we believe the borrowing rates reflect the prevailing market rates available for similar debt instruments.

		The Company has determined its derivative warrant liability and its derivative additional investment rights liability to be Level 2 fair value measurements and has used the binomial lattice model valuation method to calculate the fair value of the derivative warrant liability and the derivative additional investment rights liability at July 31, 2013, 2012 and 2011. See Note 10 – Derivative Liabilities.
Use of Estimates	'	'
		Use of Estimates
		The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods.

		The Company evaluates its estimates, including those related to bad debts, long lived assets (including patents) impairment valuations, debt obligations, derivatives, convertible preferred shares, long-term contracts, and contingencies and litigation, on an ongoing basis. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

		Critical accounting estimates are reviewed and discussed with the audit committee of the board of directors. The Company considers an accounting estimate to be critical if it requires assumptions to be made that were uncertain at the time the estimate was made, if changes in the estimate if different estimates that could have been selected would have a material impact on our results of operations or financial condition.
Effects of Recent Accounting Pronouncements	'	'
		Effects of Recent Accounting Pronouncements

		Recently Adopted Accounting Pronouncements
		In May 2011, the FASB issued further guidance on fair value measurements and disclosures which requires the categorization by level for items that are only required to be disclosed at fair value and information about transfers between Level 1 and Level 2. In addition, the update provides guidance on measuring the fair value of financial instruments managed within a portfolio and the application of premiums and discounts on fair value measurements. The guidance requires additional disclosure for Level 3 measurements regarding the sensitivity of fair value to changes in unobservable inputs and any interrelationships between those inputs. The guidance was effective for the Company’s interim period ended April 30, 2012. The adoption of this new accounting guidance did not have a material impact on the Company’s consolidated financial statements.

		In June 2011, the FASB issued guidance regarding the presentation of Comprehensive Income within financial statements. The guidance was effective for the Company’s annual fiscal period ended July 31, 2013. The adoption of this new accounting guidance did not have a material impact on the Company’s consolidated financial statements.
