Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Organization and Business | 1. Organization and Business All references to “PURE,” “we”, “our,” and “us” refer to PURE Bioscience, Inc. and our wholly owned subsidiary. PURE Bioscience, Inc. is focused on developing and commercializing our proprietary antimicrobial products that provide solutions to the health and environmental challenges of pathogen and hygienic control. Our technology platform is based on patented stabilized ionic silver, and our initial products contain silver dihydrogen citrate, or SDC. SDC is a broad-spectrum, non-toxic antimicrobial agent that is manufactured as a liquid delivered in various concentrations. We currently distribute and contract the manufacture and distribution of our SDC-based disinfecting and sanitizing products. We also contract manufacture and sell SDC-based formulations to manufacturers for use as a raw material ingredient in the production of personal care products. We believe our technology platform has potential application in a number of industries. We intend to focus our current resources on providing food safety solutions to the food industry. We were incorporated in the state of California in August 1992 as Innovative Medical Services. In September 2003, we changed our name to PURE Bioscience. In March 2011, we reincorporated in the state of Delaware. We operate in one business segment. Liquidity and Going Concern We have a history of recurring losses, and as of July 31, 2022 we have incurred a cumulative net loss of $ 129,000,000 3,491,000 1,853,000 2,499,000 3,391,000 Our future capital requirements depend on numerous forward-looking factors. These factors may include, but are not limited to, the following: the acceptance of, and demand for, our products; our success and the success of our partners in selling our products; our success and the success of our partners in obtaining regulatory approvals to sell our products; the costs of further developing our existing products and technologies; the extent to which we invest in new product and technology development; and the costs associated with the continued operation, and any future growth, of our business. The outcome of these and other forward-looking factors will substantially affect our liquidity and capital resources. Until we can continually generate positive cash flow from operations, we will need to continue to fund our operations with the proceeds of offerings of our equity and debt securities. However, we cannot ensure that additional financing will be available when needed or that, if available, financing will be obtained on terms favorable to us or to our stockholders. If we raise additional funds from the issuance of equity securities, substantial dilution to our existing stockholders would likely result. If we raise additional funds by incurring debt financing, the terms of the debt may involve significant cash payment obligations as well as covenants and specific financial ratios that may restrict our ability to operate our business. |

Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements include the consolidated accounts of PURE Bioscience, Inc. and its wholly owned subsidiary, ETIH2O Inc., a Nevada corporation. ETIH2O Inc. has no business and no material assets or liabilities and there have been no significant transactions related to ETIH2O Inc. during the periods presented in the consolidated financial statements. All inter-company balances and transactions have been eliminated. Revenue Recognition Effective August 1, 2018, we adopted the Financial Accounting Standards Board or the FASB, Accounting Standards Codification or ASC, Topic 606, Revenue from Contracts with Customers or Topic 606. Under Topic 606, revenue is recognized at an amount that reflects the consideration to which we expect to be entitled in exchange for transferring goods or services to a customer. This principle is applied using the following 5-step process: 1. Identify the contract with the customer 2. Identify the performance obligations in the contract 3. Determine the transaction price 4. Allocate the transaction price to the performance obligations in the contract 5. Recognize revenue when (or as) each performance obligation is satisfied Under Topic 606, we recognize revenue when we satisfy a performance obligation by transferring control of the promised goods or services to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Our technology platform is based on patented stabilized ionic silver, and our initial products contain silver dihydrogen citrate, or SDC. SDC is a broad-spectrum, non-toxic antimicrobial agent, which offers 24-hour residual protection and formulates well with other compounds. We sell various configurations and dilutions of SDC direct to customers and through distributors. We currently offer PURE ® ® Contract terms for unit price, quantity, shipping and payment are governed by sales agreements and purchase orders which we consider to be a customer’s contract in all cases. The unit price is considered the observable stand-alone selling price for the arrangements. Any promotional or sales discounts are applied evenly to the units sold for purposes of calculating standalone selling price. Product sales generally consist of a single performance obligation that we satisfy at a point in time. We recognize product revenue when the following events have occurred: (a) we have transferred physical possession of the products, (b) we have a present right to payment, (c) the customer has legal title to the products, and (d) the customer bears significant risks and rewards of ownership of the products. Our direct customer and distributor sales are invoiced based on received purchase orders. Our payment terms on invoiced direct customer and distributor sales range between 30 and 90 days after we satisfy our performance obligation. The majority of our customers are on 30 day payment terms. We currently offer no right of return on invoiced sales and maintain no allowance for sales returns. Shipping and handling are treated as activities to fulfill promises to customers and any amounts billed to a customer, if applicable, represent revenues earned for the goods provided. Costs related to such shipping and handling billings are classified as cost of sales. We do not have significant categories of revenue that may impact how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors. A summary of our revenue by product type for the fiscal years ended July 31, 2022 and 2021 is as follows: Summary of Revenue by Product July 31, 2022 2021 PURE Hard Surface $ 1,498,000 $ 3,563,947 SILVÉRION 315,000 134,053 $ 1,813,000 $ 3,698,000 Variable Consideration We record revenue from customers in an amount that reflects the transaction price we expect to be entitled to after transferring control of those goods or services. From time to time, we offer sales promotions on our products such as discounts. Variable consideration is estimated at contract inception only to the extent that it is probable that a significant reversal of revenue will not occur. Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America, or GAAP, requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements, and the disclosures made in the accompanying notes to the consolidated financial statements. Actual results could differ materially from those estimates. Those estimates and assumptions include estimates for reserves of uncollectible accounts, inventory obsolescence, depreciable lives of property and equipment, analysis of impairments of recorded long-term tangible and intangible assets, realization of deferred tax assets, accruals for potential liabilities and assumptions made in valuing stock instruments issued for services. Cash and Cash Equivalents Cash and cash equivalents consist of cash and highly liquid investments with original maturities from the purchase date of three months or less. Restricted Cash The Company is required to maintain $ 75,000 Accounts Receivable Trade accounts receivable are recorded net of allowances for doubtful accounts. We evaluate the collectability of our trade accounts receivable based on a number of factors. In circumstances where we becomes aware of a specific customer’s inability to meet its financial obligations to the Company, a specific reserve for bad debts is estimated and recorded, which reduces the recognized receivable to the estimated amount the Company believes will ultimately be collected. In addition to specific customer identification of potential bad debts, bad debt charges are recorded based on our historical losses and an overall assessment of past due trade accounts receivable outstanding. Management determined no Inventories Inventories are stated at the lower of cost or net realizable value, and net of a valuation allowance for potential excess or obsolete material. Cost is determined using the average cost method. We regularly review our inventory quantities on hand and record a provision for excess and obsolete inventory based primarily on our estimated forecast of product demand and our ability to sell the product(s) concerned. Demand for our products can fluctuate significantly. Factors that could affect demand for our products include unanticipated changes in consumer preferences, general market conditions or other factors, which may result in cancellations of advance orders or a reduction in the rate of reorders placed by customers. Additionally, our management’s estimates of future product demand may be inaccurate, which could result in an understated or overstated provision required for excess and obsolete inventory. At July 31, 2022 and 2021, the Company determined that a reserve for inventory obsolescence of $ 75,000 150,000 Property, Plant and Equipment Property, plant and equipment is stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets. The estimated useful lives of our property, plant, and equipment range from three to ten years. Capitalized costs associated with leasehold improvements are depreciated over the lesser of the useful life of the asset or the remaining life of the lease. Depreciation is generally included in selling, general and administrative expense. Depreciation related to manufacturing is systematically allocated to inventory produced, and expensed through cost of goods sold at the time inventory is sold. Management assesses the carrying value of property and equipment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. If there is indication of impairment, management prepares an estimate of future cash flows expected to result from the use of the asset and its eventual disposition. If these cash flows are less than the carrying amount of the asset, an impairment loss is recognized to write down the asset to its estimated fair value. For the years ended July 31, 2022 and 2021, Company Management determined there were no Patents We have filed a number of patent applications with the United States Patent and Trademark Office and in foreign countries. Certain legal and related costs incurred in connection with pending patent applications have been capitalized. Costs related to successful patent applications are amortized over the lesser of the remaining useful life of the related technology or the remaining patent life, commencing on the date the patent is issued. Capitalized costs related to patent applications are expensed in the period in which a determination is made not to pursue such applications. Impairment of Long-Lived Assets In accordance with GAAP, if indicators of impairment exist, we assess the recoverability of the affected long-lived assets, including our capitalized patent costs, by determining whether the carrying value of such assets can be recovered through undiscounted future operating cash flows. If impairment is indicated, we measure the amount of such impairment by comparing the carrying value of the asset to the fair value of the asset and we record the impairment as a reduction in the carrying value of the related asset and a charge to operating results. Estimating the undiscounted future cash flows associated with long-lived assets requires judgment, and assumptions could differ materially from actual results. As of July 31, 2022, management performed its annual impairment test and determined that its forecasted operations could no longer support the $ 299,000 Shipping and Handling Costs Shipping and handling costs incurred by us for product shipments are included in cost of goods sold. Research and Development Costs Research and development costs are expensed as incurred. Share-Based Compensation We periodically issue stock options and restricted stock awards to employees and non-employees in non-capital raising transactions for services and for financing costs. We account for such grants issued and vesting to employees based on ASC 718, whereby the value of the award is measured on the date of grant and recognized as compensation expense on the straight-line basis over the vesting period. We estimate the fair value of share-based payment awards at the date of grant using the Black-Scholes option valuation model. The Black-Scholes option valuation model requires the input of subjective assumptions, including price volatility of the underlying stock, risk-free interest rate, dividend yield, and expected life of the option. Share-based compensation expense is based on awards ultimately expected to vest, and therefore is reduced by expected forfeitures. Fair Value Measurements The Company determines the fair value of its assets and liabilities based on the exchange price in U.S. dollars that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value maximize the use of observable inputs and minimize the use of unobservable inputs. The Company uses a fair value hierarchy with three levels of inputs, of which the first two are considered observable and the last unobservable, to measure fair value: ● 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 can be 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 fair value of the assets or liabilities. The carrying amounts of financial instruments such as cash, accounts receivable, inventories, accounts payable and accrued liabilities, approximate the related fair values due to the short-term maturities of these instruments. Concentrations Gross sales 14 13 10 10 11 10 Accounts receivable. 15 13 17 15 10 Purchases. 19 36 Accounts payable. 25 50 Income Taxes We recognize deferred tax assets and liabilities for temporary differences between the tax basis of assets and liabilities and the amounts at which they are carried in the financial statements based upon the enacted tax rates in effect for the year in which the differences are expected to reverse. A valuation allowance is established to reduce deferred tax assets to the amount expected to be realized. Income (Loss) Per Share Basic net loss per common share is computed as net loss divided by the weighted average number of common shares outstanding for the period. Our diluted net loss per common share is the same as our basic net loss per common share because we incurred a net loss during each period presented, and the potentially dilutive securities from the assumed exercise of all outstanding stock options, restricted stock units, and warrants would have an anti-dilutive effect. As of July 31, 2022 and 2021, stock options, warrants and shares issuable under restricted stock unit awards of 7,291,625 10,984,390 , respectively, have been excluded from the computation of diluted shares outstanding. Segments We operate in one Recent Accounting Pronouncements In June 2016, the FASB issued ASU No. 2016-13, Credit Losses - Measurement of Credit Losses on Financial Instruments or ASC 326. The standard significantly changes how entities will measure credit losses for most financial assets, including accounts and notes receivable. The standard will replace today’s “incurred loss” approach with an “expected loss” model, under which companies will recognize allowances based on expected rather than incurred losses. Entities will apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. As small business filer, the standard will be effective for us for interim and annual reporting periods beginning after December 15, 2022. The Company is currently assessing the impact of adopting this standard on the Company’s financial statements and related disclosures. In May 2021, the FASB issued ASU 2021-04, Earnings Per Share (Topic 260), Debt — Modifications and Extinguishments (Subtopic 470-50), Compensation — Stock Compensation (Topic 718), and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40): Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options or ASU 2021-04. ASU 2021-04 provides guidance as to how an issuer should account for a modification of the terms or conditions or an exchange of a freestanding equity-classified written call option (i.e., a warrant) that remains classified after modification or exchange as an exchange of the original instrument for a new instrument. An issuer should measure the effect of a modification or exchange as the difference between the fair value of the modified or exchanged warrant and the fair value of that warrant immediately before modification or exchange and then apply a recognition model that comprises four categories of transactions and the corresponding accounting treatment for each category (equity issuance, debt origination, debt modification, and modifications unrelated to equity issuance and debt origination or modification). ASU 2021-04 is effective for all entities for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. An entity should apply the guidance provided in ASU 2021-04 prospectively to modifications or exchanges occurring on or after the effective date. Early adoption is permitted for all entities, including adoption in an interim period. If an entity elects to early adopt ASU 2021-04 in an interim period, the guidance should be applied as of the beginning of the fiscal year that includes that interim period. The adoption of ASU 2021-04 is not expected to have any impact on the Company’s consolidated financial statement presentation or disclosures. Recent accounting pronouncements issued by the FASB, including its Emerging Issues Task Force, the American Institute of Certified Public Accountants, and the Securities and Exchange Commission did not or are not believed by management to have a material impact on the Company’s present or future consolidated financial statement presentation or disclosures. |

While we have experienced some delays related to final third-party validation of certain of our products and product rollouts by customers using PURE Control, we did not experience a material disruption to our business. In addition, we previously benefited from increased demand from our customers for our PURE Hard Surface product due to a focus on surface disinfecting in response to attempting to prevent COVID-19 transmission. We subsequently experienced an abatement in such demand. Such abatement has not stabilized and we cannot assure you that demand will stabilize in the future. Additionally, we experienced supply chain issues with our various plastic packaging configurations and citric acid. Further, on a go-forward basis, we cannot guarantee the overall economic conditions will not affect our business, as these conditions may significantly negatively impact all aspects of our business. Our business is dependent on the continued health and productivity of our employees, including our sales staff and corporate management team. The extent to which the COVID-19 pandemic or other health-related pandemics impacts our business, sales, results of operations and financial condition will depend on future developments, which are highly uncertain and cannot be predicted. Even after the COVID-19 pandemic or other health-related pandemics has subsided, we may experience significant impacts to our business as a result of its global economic impact, including any economic downturn or recession that has occurred or may occur in the future. See the section titled “Risk Factors - The COVID-19 pandemic or other health-related pandemics could adversely affect our business, financial condition and results of operations.” Legal From time to time, we could become involved in disputes and various litigation matters that arise in the normal course of business. Lawsuits against us or our officers or directors by employees, former employees, stockholders, partners, customers, or others, or actions taken by regulatory authorities, could be very costly and substantially disrupt our business. Such lawsuits and actions are not uncommon, and we may not be able to resolve such disputes or actions on terms favorable to us, and there may not be sufficient capital resources available to defend such actions effectively, or at all. As of July 31, 2022, there were no material lawsuits against the Company. Manufacturing Effective June 9, 2019, we entered into a five-year manufacturing supply agreement with Intercon Chemical Company or ICC with a three-year renewal term option or the Manufacturing Supply Agreement. The agreement consists of manufacturing, packaging, and distribution of PURE’s SDC-based products and contains no mandatory purchase commitment levels. The Manufacturing Supply Agreement provides: ● ICC licenses PURE’s patents and technology know-how for the non-exclusive manufacture of PURE’s SDC-based products. ● ICC will invest in plant improvements to allow for expanded SDC production. ● ICC’s R&D team will collaborate on SDC product line development. The Manufacturing Supply Agreement may be terminated by mutual written consent, or by either party upon the material breach of the terms of the agreement by the other party. Silver is the primary active ingredient in SDC and is a readily available commodity. The other active and inactive ingredients in our products are readily available from multiple sources. |

Share-Based Payment Arrangement [Abstract] | |
Share-Based Compensation | 7. Share-Based Compensation Restricted Stock Units We issue restricted stock unit awards or RSUs, to key management and as compensation for services to consultants and others. The RSUs typically vest over a one to three-year period and carry a ten-year term. Each RSU represents the right to receive one share of common stock, issuable at the time the RSU subsequently settles, as set forth in the Restricted Stock Unit Agreement. We determine that fair value of those awards at the date of grant, and amortize those awards as an expense over the vesting period of the award. The shares earned under the grant are usually issued when the award settles at the end of the term. As of July 31, 2021, there were 2,012,500 1,679,167 During the fiscal years ended July 31, 2022 and 2021, we recognized $ 102,000 83,000 166,666 166,667 62,000 166,667 0.75 During the fiscal year ended July 31, 2022, 800,000 1,212,500 1,045,833 These RSUs are issued upon settlement date which is defined as “for each Vested Unit, the earliest of (i) the ten-year anniversary of the Grant Date; (ii) sixty days after the date the Grantee’s Service ceases for any reason and such cessation constitutes a “separation from service” within the meaning of Section 409A of the Code; (iii) the date of Grantee’s death or (iv) the date of a Change in Control that constitutes a “change in control event” within the meaning of Section 409A of the Code”.

Share-based compensation expense is recognized over the vesting period using the straight-line method. The fair value of stock options was estimated at the grant date using the following weighted average assumptions: Schedule of Fair Value Assumptions For the years ended July 31, 2022 2021 Volatility 88.35 % 87.76 % Risk-free interest rate 1.17 % 0.92 % Dividend yield 0.0 % 0.0 % Expected life 5.59 5.30 Volatility is the measure by which our stock price is expected to fluctuate during the expected term of an option. Volatility is derived from the historical daily change in the market price of our common stock, as we believe that historical volatility is the best indicator of future volatility. The risk-free interest rates used in the Black-Scholes calculations are based on the prevailing U.S. Treasury yield as determined by the U.S. Federal Reserve. We have never paid dividends on our common stock and do not anticipate paying dividends on our common stock in the foreseeable future. Accordingly, we have assumed no dividend yield for purposes of estimating the fair value of our share-based compensation. The weighted average expected life of options was estimated using the average of the contractual term and the weighted average vesting term of the options. Certain options granted to consultants are subject to variable accounting treatment and are required to be revalued until vested. |

Income Taxes | 9. Income Taxes We file federal and state consolidated tax returns with our subsidiaries. Our income tax provision for the years ended July 31, 2022 and 2021 was $ 1,650 At July 31, 2022, we had federal and state tax net operating loss carry-forwards of approximately $ 107.3 million and $ 63.3 million, respectively. Utilization of the net operating loss carry-forwards may be subject to a substantial annual limitation due to ownership change limitations that may have occurred or that could occur in the future, as required by Section 382 of the Internal Revenue Code as well as similar state provisions. These ownership changes may limit the amount of net operating loss carry-forwards that can be utilized annually to offset future taxable income and tax, respectively. In general, an ownership change, as defined by Section 382 of the Internal Revenue Code results from a transaction or series of transactions over a three-year period resulting in an ownership change of more than 50 percentage points of the outstanding stock of a company by certain stockholders or public groups. Since our formation, we have raised capital through the issuance of capital stock on several occasions (both before and after our initial public offering in 1996) which, combined with the purchasing stockholders’ subsequent disposition of those shares, may have resulted in such an ownership change, or could result in an ownership change in the future upon subsequent disposition. While we do not believe that we have experienced an ownership change, the pertinent tax rules related thereto are complex and subject to varying interpretations, and thus complete assurance cannot be provided that the taxing authorities would not take an alternative position. Our current federal tax loss carry-forwards began expiring in the year ended July 31, 2020 and, unless previously utilized, all but $ 5.9 July 31, 2038 5.9 Our state tax loss carry-forwards began to expire in the year ending July 31, 2029, and will completely expire in the year ending July 31, 2040.

Revenue Recognition | Revenue Recognition Effective August 1, 2018, we adopted the Financial Accounting Standards Board or the FASB, Accounting Standards Codification or ASC, Topic 606, Revenue from Contracts with Customers or Topic 606. Under Topic 606, revenue is recognized at an amount that reflects the consideration to which we expect to be entitled in exchange for transferring goods or services to a customer. This principle is applied using the following 5-step process: 1. Identify the contract with the customer 2. Identify the performance obligations in the contract 3. Determine the transaction price 4. Allocate the transaction price to the performance obligations in the contract 5. Recognize revenue when (or as) each performance obligation is satisfied Under Topic 606, we recognize revenue when we satisfy a performance obligation by transferring control of the promised goods or services to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Our technology platform is based on patented stabilized ionic silver, and our initial products contain silver dihydrogen citrate, or SDC. SDC is a broad-spectrum, non-toxic antimicrobial agent, which offers 24-hour residual protection and formulates well with other compounds. We sell various configurations and dilutions of SDC direct to customers and through distributors. We currently offer PURE ® ® Contract terms for unit price, quantity, shipping and payment are governed by sales agreements and purchase orders which we consider to be a customer’s contract in all cases. The unit price is considered the observable stand-alone selling price for the arrangements. Any promotional or sales discounts are applied evenly to the units sold for purposes of calculating standalone selling price. Product sales generally consist of a single performance obligation that we satisfy at a point in time. We recognize product revenue when the following events have occurred: (a) we have transferred physical possession of the products, (b) we have a present right to payment, (c) the customer has legal title to the products, and (d) the customer bears significant risks and rewards of ownership of the products. Our direct customer and distributor sales are invoiced based on received purchase orders. Our payment terms on invoiced direct customer and distributor sales range between 30 and 90 days after we satisfy our performance obligation. The majority of our customers are on 30 day payment terms. We currently offer no right of return on invoiced sales and maintain no allowance for sales returns. Shipping and handling are treated as activities to fulfill promises to customers and any amounts billed to a customer, if applicable, represent revenues earned for the goods provided. Costs related to such shipping and handling billings are classified as cost of sales. We do not have significant categories of revenue that may impact how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors. A summary of our revenue by product type for the fiscal years ended July 31, 2022 and 2021 is as follows: Summary of Revenue by Product July 31, 2022 2021 PURE Hard Surface $ 1,498,000 $ 3,563,947 SILVÉRION 315,000 134,053 $ 1,813,000 $ 3,698,000 Variable Consideration We record revenue from customers in an amount that reflects the transaction price we expect to be entitled to after transferring control of those goods or services. From time to time, we offer sales promotions on our products such as discounts. Variable consideration is estimated at contract inception only to the extent that it is probable that a significant reversal of revenue will not occur. |
Use of Estimates | Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America, or GAAP, requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements, and the disclosures made in the accompanying notes to the consolidated financial statements. Actual results could differ materially from those estimates. Those estimates and assumptions include estimates for reserves of uncollectible accounts, inventory obsolescence, depreciable lives of property and equipment, analysis of impairments of recorded long-term tangible and intangible assets, realization of deferred tax assets, accruals for potential liabilities and assumptions made in valuing stock instruments issued for services. |
Cash and Cash Equivalents | Cash and Cash Equivalents Cash and cash equivalents consist of cash and highly liquid investments with original maturities from the purchase date of three months or less. |
Restricted Cash | Restricted Cash The Company is required to maintain $ 75,000 |
Accounts Receivable | Accounts Receivable Trade accounts receivable are recorded net of allowances for doubtful accounts. We evaluate the collectability of our trade accounts receivable based on a number of factors. In circumstances where we becomes aware of a specific customer’s inability to meet its financial obligations to the Company, a specific reserve for bad debts is estimated and recorded, which reduces the recognized receivable to the estimated amount the Company believes will ultimately be collected. In addition to specific customer identification of potential bad debts, bad debt charges are recorded based on our historical losses and an overall assessment of past due trade accounts receivable outstanding. Management determined no |
Inventories | Inventories Inventories are stated at the lower of cost or net realizable value, and net of a valuation allowance for potential excess or obsolete material. Cost is determined using the average cost method. We regularly review our inventory quantities on hand and record a provision for excess and obsolete inventory based primarily on our estimated forecast of product demand and our ability to sell the product(s) concerned. Demand for our products can fluctuate significantly. Factors that could affect demand for our products include unanticipated changes in consumer preferences, general market conditions or other factors, which may result in cancellations of advance orders or a reduction in the rate of reorders placed by customers. Additionally, our management’s estimates of future product demand may be inaccurate, which could result in an understated or overstated provision required for excess and obsolete inventory. At July 31, 2022 and 2021, the Company determined that a reserve for inventory obsolescence of $ 75,000 150,000 |
Property, Plant and Equipment | Property, Plant and Equipment Property, plant and equipment is stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets. The estimated useful lives of our property, plant, and equipment range from three to ten years. Capitalized costs associated with leasehold improvements are depreciated over the lesser of the useful life of the asset or the remaining life of the lease. Depreciation is generally included in selling, general and administrative expense. Depreciation related to manufacturing is systematically allocated to inventory produced, and expensed through cost of goods sold at the time inventory is sold. Management assesses the carrying value of property and equipment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. If there is indication of impairment, management prepares an estimate of future cash flows expected to result from the use of the asset and its eventual disposition. If these cash flows are less than the carrying amount of the asset, an impairment loss is recognized to write down the asset to its estimated fair value. For the years ended July 31, 2022 and 2021, Company Management determined there were no |
Patents | Patents We have filed a number of patent applications with the United States Patent and Trademark Office and in foreign countries. Certain legal and related costs incurred in connection with pending patent applications have been capitalized. Costs related to successful patent applications are amortized over the lesser of the remaining useful life of the related technology or the remaining patent life, commencing on the date the patent is issued. Capitalized costs related to patent applications are expensed in the period in which a determination is made not to pursue such applications. |
Impairment of Long-Lived Assets | Impairment of Long-Lived Assets In accordance with GAAP, if indicators of impairment exist, we assess the recoverability of the affected long-lived assets, including our capitalized patent costs, by determining whether the carrying value of such assets can be recovered through undiscounted future operating cash flows. If impairment is indicated, we measure the amount of such impairment by comparing the carrying value of the asset to the fair value of the asset and we record the impairment as a reduction in the carrying value of the related asset and a charge to operating results. Estimating the undiscounted future cash flows associated with long-lived assets requires judgment, and assumptions could differ materially from actual results. As of July 31, 2022, management performed its annual impairment test and determined that its forecasted operations could no longer support the $ 299,000 |
Shipping and Handling Costs | Shipping and Handling Costs Shipping and handling costs incurred by us for product shipments are included in cost of goods sold. |
Research and Development Costs | Research and Development Costs Research and development costs are expensed as incurred. |
Share-Based Compensation | Share-Based Compensation We periodically issue stock options and restricted stock awards to employees and non-employees in non-capital raising transactions for services and for financing costs. We account for such grants issued and vesting to employees based on ASC 718, whereby the value of the award is measured on the date of grant and recognized as compensation expense on the straight-line basis over the vesting period. We estimate the fair value of share-based payment awards at the date of grant using the Black-Scholes option valuation model. The Black-Scholes option valuation model requires the input of subjective assumptions, including price volatility of the underlying stock, risk-free interest rate, dividend yield, and expected life of the option. Share-based compensation expense is based on awards ultimately expected to vest, and therefore is reduced by expected forfeitures. |
Fair Value Measurements | Fair Value Measurements The Company determines the fair value of its assets and liabilities based on the exchange price in U.S. dollars that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value maximize the use of observable inputs and minimize the use of unobservable inputs. The Company uses a fair value hierarchy with three levels of inputs, of which the first two are considered observable and the last unobservable, to measure fair value: ● 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 can be 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 fair value of the assets or liabilities. The carrying amounts of financial instruments such as cash, accounts receivable, inventories, accounts payable and accrued liabilities, approximate the related fair values due to the short-term maturities of these instruments. |

Income Taxes | Income Taxes We recognize deferred tax assets and liabilities for temporary differences between the tax basis of assets and liabilities and the amounts at which they are carried in the financial statements based upon the enacted tax rates in effect for the year in which the differences are expected to reverse. A valuation allowance is established to reduce deferred tax assets to the amount expected to be realized. |
Income (Loss) Per Share | Income (Loss) Per Share Basic net loss per common share is computed as net loss divided by the weighted average number of common shares outstanding for the period. Our diluted net loss per common share is the same as our basic net loss per common share because we incurred a net loss during each period presented, and the potentially dilutive securities from the assumed exercise of all outstanding stock options, restricted stock units, and warrants would have an anti-dilutive effect. As of July 31, 2022 and 2021, stock options, warrants and shares issuable under restricted stock unit awards of 7,291,625 10,984,390 , respectively, have been excluded from the computation of diluted shares outstanding. |

Recent Accounting Pronouncements | Recent Accounting Pronouncements In June 2016, the FASB issued ASU No. 2016-13, Credit Losses - Measurement of Credit Losses on Financial Instruments or ASC 326. The standard significantly changes how entities will measure credit losses for most financial assets, including accounts and notes receivable. The standard will replace today’s “incurred loss” approach with an “expected loss” model, under which companies will recognize allowances based on expected rather than incurred losses. Entities will apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. As small business filer, the standard will be effective for us for interim and annual reporting periods beginning after December 15, 2022. The Company is currently assessing the impact of adopting this standard on the Company’s financial statements and related disclosures. In May 2021, the FASB issued ASU 2021-04, Earnings Per Share (Topic 260), Debt — Modifications and Extinguishments (Subtopic 470-50), Compensation — Stock Compensation (Topic 718), and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40): Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options or ASU 2021-04. ASU 2021-04 provides guidance as to how an issuer should account for a modification of the terms or conditions or an exchange of a freestanding equity-classified written call option (i.e., a warrant) that remains classified after modification or exchange as an exchange of the original instrument for a new instrument. An issuer should measure the effect of a modification or exchange as the difference between the fair value of the modified or exchanged warrant and the fair value of that warrant immediately before modification or exchange and then apply a recognition model that comprises four categories of transactions and the corresponding accounting treatment for each category (equity issuance, debt origination, debt modification, and modifications unrelated to equity issuance and debt origination or modification). ASU 2021-04 is effective for all entities for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. An entity should apply the guidance provided in ASU 2021-04 prospectively to modifications or exchanges occurring on or after the effective date. Early adoption is permitted for all entities, including adoption in an interim period. If an entity elects to early adopt ASU 2021-04 in an interim period, the guidance should be applied as of the beginning of the fiscal year that includes that interim period. The adoption of ASU 2021-04 is not expected to have any impact on the Company’s consolidated financial statement presentation or disclosures. Recent accounting pronouncements issued by the FASB, including its Emerging Issues Task Force, the American Institute of Certified Public Accountants, and the Securities and Exchange Commission did not or are not believed by management to have a material impact on the Company’s present or future consolidated financial statement presentation or disclosures. |
