Organization, Consolidation and Presentation Of Financial Statements [Abstract]
Basis of Accounting [Text Block]	1. ORGANIZATION AND BASIS OF PRESENTATION The accompanying consolidated financial statements include the accounts of Crossroads Systems, Inc. and its wholly-owned subsidiaries (“Crossroads” or the “Company”). Headquartered in Austin, Texas, Crossroads, a Delaware corporation, is an intellectual property licensing company. Founded in 1996 as a product solutions company, Crossroads created some of the storage industry’s most fundamental patents and has licensed patents to more than 50 companies since 2000. On March 22, 2016, the Company announced the sale of its product business and all related assets to Canadian-based StrongBox Data Solutions, Inc. (“SDSI”) for gross proceeds of $ 1.9 The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany transactions have been eliminated in consolidation. The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Company has accumulated significant losses as it developed its past products. Our operations are funded by cash and cash equivalents, as well as from revenue provided by IP licensing, royalties and other revenue. We may also generate revenue from other sources as described in Liquidity and Capital Resources, including without limitation, through obtaining a favorable judgment or settlement in our ongoing litigation concerning infringement of our intellectual property, successfully monetizing all or a portion of the non-‘972 patents, or pursuing other strategic opportunities to generate revenue. If we are not able to obtain additional sources of revenue through these or alternative means, the Company may not have sufficient funds to continue to operate the business. These conditions raise substantial doubt about the Company’s ability to continue as a going concern. These financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might be necessary should the Company be unable to continue as a going concern for a reasonable period of time. The investment in KIP CR P1 LP (which we refer to as the “partnership”) of which the Company is a limited partner and of which an affiliate of Fortress Investment Group (“Fortress”) is the general partner, is accounted for using the equity method. The current investment balance is nominal at April 30, 2017. The preparation of the consolidated financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates, and such differences may be material to the consolidated financial statements. Certain prior period amounts have been reclassified to conform to the current period presentation. The reclassification includes assets, liabilities, and certain expenses in sales and marketing, research and development, and general and administrative related to discontinued operations. The amounts for the prior periods have been reclassified to be consistent with the current period presentation and have no impact on previously reported financials. Cash and cash equivalents consist of cash on deposit and highly liquid investments with original maturities of 90 days or less at date of purchase. While the Company’s cash and cash equivalents are on deposit with high quality FDIC and Association of German Banks insured financial institutions, at times such deposits exceed insured limits. As of April 30, 2017, total uninsured deposits were $ 2.1 Restricted cash amounted to $ 0.6 On October 30, 2015, the Company entered into an agreement with TQ Zeta LLC, an affiliate of Techquity, and Intrepidus Holdings LLC (collectively, “Techquity”), pursuant to which Techquity will share in the revenue generated from the ‘972 patent litigation. For consideration of $ 10.0 52 20 40 20 100 12 100 0.9 3.3 0.6 Basic loss per share is computed by dividing net loss available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share is computed by giving effect to all dilutive potential common shares that were outstanding during the period. Basic earnings per share excludes the dilutive effect of common stock equivalents such as stock options and warrants, while earnings per share, assuming dilution, includes such dilutive effects. Future weighted-average shares outstanding calculations will be impacted by the following factors, among others: (i) the ongoing issuance of common stock associated with stock option and warrant exercises; (ii) any fluctuations in the Company’s stock price, which could cause changes in the number of common stock equivalents included in the earnings per share, assuming dilution computation; and (iii) the issuance of common stock to effect business combinations should the Company enter into such transactions. The Company has excluded all outstanding common stock equivalents from the calculation of diluted net loss per share because all such common stock equivalents are antidilutive for all periods presented. The total number of common stock equivalents excluded from the diluted net loss per common share calculation was 3,234,495 3,150,497 368,765 2,591,257 274,473 Net loss available to common stockholders is calculated by deducting from net loss, preferred dividends paid and accrued of $ 136,000 129,000 In August 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-15 requiring management to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern, which is currently performed by the external auditors. Management will be required to perform this assessment for both interim and annual reporting periods and must make certain disclosures if it concludes that substantial doubt exists. This ASU is effective for annual periods, and interim periods within those annual periods, beginning on or after December 15, 2016. The adoption of this guidance is not expected to have a material effect on our financial statements. In March 2016, the FASB issued ASU 2016-09 amending several aspects of share-based payment accounting. This guidance requires all excess tax benefits and tax deficiencies to be recorded in the income statement when the awards vest or are settled, with prospective application required. The guidance also changes the classification of such tax benefits or tax deficiencies on the statement of cash flows from a financing activity to an operating activity, with retrospective or prospective application allowed. Additionally, the guidance requires the classification of employee taxes paid when an employer withholds shares for tax-withholding purposes as a financing activity on the statement of cash flows, with retrospective application required. This ASU is effective for annual periods, and interim periods after those annual periods, beginning after December 15, 2016. Early adoption is permitted. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements and related disclosures.

FAIR VALUE MEASUREMENT

Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	2. FAIR VALUE MEASUREMENT Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. To increase the comparability of fair value measurements, a three-tier fair value hierarchy, which prioritizes the inputs used in the valuation methodologies, is applied as follows: Level 1 – Valuations based on quoted prices for identical assets and liabilities in active markets. Level 2 – Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3 – Valuations based on unobservable inputs reflecting management’s assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment. As of April 30, 2017, the fair value of the Company’s financial instruments, including cash and cash equivalents, accounts receivable, accounts payable and accrued expenses, approximates book value due to the short maturity of these instruments. As of April 30, 2017 and October 31, 2016, the Company held no items which are reported at fair value.

COMMITMENTS AND CONTINGENCIES Leases In accordance with the terms of the March 22, 2016 sale of the Company’s product division, the Company’s office space and equipment lease obligations have been assigned to the purchaser. Legal Proceedings Intellectual Property Litigation The Company has a number of ongoing lawsuits and related proceedings as described below. In discussing these patent litigation proceedings, the following terms will be used: A “Markman hearing” in a patent infringement case is a pre-trial hearing in U.S. District Court, in which the Court hears arguments regarding the meanings of key words used in a disputed patent claim. The outcome of a Markman hearing can play a significant role in whether findings of infringement and validity are made by the Court or by the jury at trial. Depending on the Court, a ruling could be received quickly or could take months after the Markman hearing. An “ Inter Partes inter partes Inter partes An “ Ex Parte Crossroads v. Dot Hill The Company filed a lawsuit on September 11, 2013 against Dot Hill Systems Corp. (“Dot Hill”) styled Crossroads Systems, Inc. v. Dot Hill Systems Corp., Civil Action No. 1:13-CV-800-SS alleging patent infringement of U.S. Patent No. 6,425,035 (the “’035 patent”) and breach of the Amended Settlement and License Agreement dated June 27, 2006 between Crossroads and Dot Hill. The action is pending. The Markman hearing was conducted October 6-7, 2014. Dot Hill moved to join two existing IPR proceedings previously filed against Crossroads by other defendants (one filed by NetApp/Oracle/Huawei and one filed by Cisco/Quantum, each as defined below) and to stay the pending litigation based on those IPR proceedings. On June 16, 2015, Judge Sparks entered the Markman order (the “Markman Order”) construing the claims in a manner favorable to Crossroads and issued an order staying the case pending resolution of the IPR proceedings. The U.S. Patent Office issued rulings in both of the IPR proceedings that Dot Hill had joined, ruling in one that the ‘035 Patent is not unpatentable in view of the prior art raised and in the other that the ‘035 Patent is unpatentable in view of different prior art. Crossroads believes the ruling of unpatentability was in error and has filed an appeal of that ruling with the Federal Circuit Court of Appeals. That appeal is on-going. If the patent asserted against Dot Hill is found partially or entirely invalid at the conclusion of the IPR proceedings, including appeal, Crossroads might be adversely impacted in the litigation proceeding against Dot Hill, including potentially losing the ability to continue with its claims of infringement. In May 2016, Crossroads filed a motion to lift the stay for limited purposes regarding Dot Hill’s failure to pay certain royalties and in July 2016 the Court denied the motion and the stay and this action remains in place. The Company has recorded revenue of approximately $ 1.3 134,000 34,000 182,000 46,000 Revenue for the six months ended April 30, 2016 and the accounts receivable balance at April 30, 2017 and October 31, 2016 are concentrated with Dot Hill. In 2015, Seagate Technologies (“Seagate”) purchased Dot Hill. The loss or bankruptcy of Seagate could adversely affect operating results. The Company has not experienced material credit losses in any of the periods presented. The level of sales to any customer may vary from quarter to quarter. However, the Company expects that significant customer concentrations will continue for the foreseeable future. Crossroads v. Oracle, Huawei, Cisco, NetApp, and Quantum These related cases were filed on October 7, 2013, November 26, 2013, and February 18, 2014 in the United States District Court for the Western District of Texas alleging infringement by these parties of one or more patents in the ‘972 patent family. The asserted patents (6,425,035, 7,934,041, 7,987,311 (the “‘311 Patent”) and 7,051,147) were subject to a Re-examination of the patents conducted in 2005-2006 by the U.S. Patent Office or were issued after the Re-examination. On May 7, 2014, these cases and the Dot Hill case were consolidated for purposes of discovery and a Markman hearing occurred on October 6 and 7, 2014. On June 16, 2015, Judge Sparks entered the Markman Order construing the claims in a manner favorable to Crossroads and entered an order staying these actions in light of the IPR proceedings. During the time Crossroads was pursuing the potential infringers of the ‘972 patent family, the Company gave companies with potentially infringing products the opportunity to license the Company’s proprietary technology. For example, NetApp, Inc. (“NetApp”) was first given notice of potential infringement in 2004. Cisco Systems, Inc. (“Cisco”)was first given notice of potential infringement in 2002. Quantum Corporation (“Quantum”) has been on notice of its potential infringement since 2006. Oracle Corporation (“Oracle”) acquired several companies that were given notice of potential infringement at least as early as 2009 and Oracle itself has been on notice since then. Despite repeated attempts by Crossroads throughout the years to negotiate licenses to the ‘972 patent family, these companies refused and left Crossroads with no alternatives but litigation. Crossroads believes these companies (and companies they have acquired) have been illegally using Crossroads’ proprietary technology and that the potential compensatory damages could be in excess of $ 200 In response to the lawsuits brought by Crossroads, collectively these defendants filed nineteen inter partes The Company filed a lawsuit on October 7, 2013 against Oracle alleging infringement of U.S. Patent Nos. 6,425,035, 7,051,147 and 7,934,041 (the case is styled Crossroads Systems, Inc. v. Oracle Corporation; Civil Action No. 1:13-cv-0895-SS (W.D. Tex., Austin Division)). The action is pending. The Markman hearing was conducted October 6-7, 2014 and on June 16, 2015, Judge Sparks entered the Markman Order construing the claims in a manner favorable to Crossroads. Oracle filed nine petitions for IPR at the U.S. Patent Office challenging the validity of each of the patents Crossroads asserted in the lawsuit against Oracle. The U.S. Patent Office granted six of those petitions. Based on the IPRs, Oracle filed a motion to stay the litigation pending the outcome of the IPR proceedings, which was granted by the Court. The U.S. Patent Office issued rulings in the IPR proceedings involving Oracle, ruling in one that the ‘035 Patent is not unpatentable over the prior art and ruling in the other five that the ‘035 Patent and ‘147 Patent are unpatentable in view of different prior art. Crossroads believes the rulings of unpatentability were in error and has appealed these rulings to the Federal Circuit Court of Appeals. Those appeals are on-going. If the patents are found partially or entirely invalid during the IPR proceedings, including appeal, Crossroads might be adversely impacted in the litigation proceeding against Oracle, including potentially losing the ability to continue with its claims of infringement. The Company filed a lawsuit on February 18, 2014 against Cisco alleging infringement of U.S. Patent Nos. 6,425,035 and 7,934,041 (the case is styled Crossroads Systems, Inc. v. Cisco Systems, Inc.; Civil Action No. 1:14-cv-00148-SS (W.D. Tex., Austin Division)). The action is pending. The Markman hearing was conducted October 6-7, 2014 and on June 16, 2015, Judge Sparks entered the Markman Order construing the claims in a manner favorable to Crossroads. Cisco is a party to three petitions for IPR filed at the U.S. Patent Office challenging the validity of each of the patents Crossroads asserted in the lawsuit against Cisco. The U.S. Patent Office granted those petitions. Based on the IPRs, Cisco filed a motion to stay the litigation pending the outcome of the IPR proceedings, which was granted by the Court. The U.S. Patent Office issued rulings in the IPR proceedings involving Cisco, ruling that the ‘035 Patent and ‘147 Patents are unpatentable in view of the cited prior art. Crossroads believes the rulings of unpatentability were in error and has appealed these rulings to the Federal Circuit Court of Appeals. Those appeals are on-going. If the patents are found partially or entirely invalid during the IPR proceedings, including appeal, Crossroads might be adversely impacted in the litigation proceeding against Cisco, including potentially losing the ability to continue with its claims of infringement. The Company filed a lawsuit on February 18, 2014 against NetApp alleging infringement of U.S. Patent Nos. 6,425,035, 7,934,041, 7,987,311 and 7,051,147 (the case is styled Crossroads Systems, Inc. v. Net App, Inc.; Civil Action No. 1:14-cv-00149-SS (W.D. Tex., Austin Division)). The action is pending. The Markman hearing was conducted October 6-7, 2014 and on June 16, 2015, Judge Sparks entered the Markman Order construing the claims in a manner favorable to Crossroads. NetApp filed seven petitions for IPR filed at the U.S. Patent Office challenging the validity of each of the patents Crossroads asserted in the lawsuit against NetApp. The U.S. Patent Office granted three of those petitions. Based on the IPRs, NetApp filed a motion to stay the litigation pending the outcome of the IPR proceedings, which was granted by the Court. The U.S. Patent Office issued rulings in the IPR proceedings involving NetApp, ruling in one that the ‘035 Patent is not unpatentable over the prior art and ruling in the others that the ‘147 Patent is unpatentable in view of different prior art. Crossroads believes the rulings of unpatentability were in error and has appealed these rulings to the Federal Circuit Court of Appeals. Those appeals are on-going. If the patents are found partially or entirely invalid during the IPR proceedings, including appeal, Crossroads might be adversely impacted in the litigation proceeding against NetApp, including potentially losing the ability to continue with its claims of infringement. On March 4, 2016, after its IPR on the ‘311 Patent was denied, NetApp filed a Reexamination request with the U.S. Patent and Trademark Office challenging the validity of the ‘311 Patent based on a subset of the prior art used in the IPR proceeding. The U.S. Patent and Trademark Office granted the request for Reexamination and issued an office action rejecting the claims of the ‘311 Patent. Crossroads believes this rejection of the claims of the ‘311 Patent to be in error just as we believe the rulings on the IPRs are in error. On September 3, 2016, the Company conducted an interview with the patent examiners to explain why we believe the ‘311 Patent to be valid over the cited prior art. This proceeding is ongoing and could be concluded in 2017. If the ‘311 Patent is found partially or entirely invalid during the Reexamination proceeding, the Company may be adversely impacted in the litigation proceeding The Company filed a lawsuit on February 18, 2014 against Quantum alleging infringement of U.S. Patent Nos. 6,425,035 and 7,934,041 (the case is styled Crossroads Systems, Inc. v. Quantum Corporation; Civil Action No. 1:14-cv-00150-SS (W.D. Tex., Austin Division)). The action is pending. The Markman hearing was conducted October 6-7, 2014 and on June 16, 2015, Judge Sparks entered the Markman Order construing the claims in a manner favorable to Crossroads. Quantum filed three petitions for IPR filed at the U.S. Patent Office challenging the validity of each of the patents Crossroads asserted in the lawsuit against Quantum. The U.S. Patent Office granted those petitions. Based on the IPRs, Quantum filed a motion to stay the litigation pending the outcome of the IPR proceedings, which was granted by the Court. The U.S. Patent Office issued rulings in the three IPR proceedings involving Quantum, ruling that the ‘035 Patent and ‘147 Patents are unpatentable in view of the cited prior art. Crossroads believes the rulings of unpatentability were in error and has appealed those rulings to the Federal Circuit Court of Appeals. Those appeals are on-going. If the patents are found partially or entirely invalid during the IPR proceedings, including appeal, Crossroads might be adversely impacted in the litigation proceeding against Quantum, including potentially losing the ability to continue with its claims of infringement. On January 23, 2017, the United States Court of Appeals for the Federal Circuit notified the Company that the oral argument date for the Company’s appeal was on March 7, 2017. The appeals before the Federal Circuit relate to the Final Written Decisions issued by the Patent Trial and Appeal Board of the U.S. Patent Office regarding IPR proceedings 2014-01207, 2014-01209, 2014-01226, 2014-01463, 2014-01544, and the IPRs joined to certain of those proceedings (IPRs 2015-00825, 2015-00854, and 2015-00852). No ruling has been made relating to the appeal and the Company is awaiting the decision.

Stockholders Equity Note [Abstract]
Stockholders' Equity Note Disclosure [Text Block]	6. STOCKHOLDERS’ EQUITY On May 25, 2016, the Company’s stockholders approved an amendment to the Company’s Certificate of Incorporation to effect a reverse stock split (the “Reverse Split”) of the outstanding shares of the Company’s common stock at a ratio of one-for-twenty at the Company’s annual meeting of stockholders. The Reverse Split was effective on June 20, 2016. Upon the effectiveness of the Reverse Split, every twenty (20) shares of the Company’s issued and outstanding common stock were automatically combined and reclassified into one (1) share of the Company’s common stock. 2013 Private Placement On March 22, 2013, the Company entered into a securities purchase agreement with certain accredited investors for the issuance and sale in a private placement of 4,231,154 2.0625 8.6 7.9 0.001 2.00 114,138 40.00 0.2019 121,979 6,346 138,000 133,000 136,000 88,000 The Series F Preferred Stock has the rights, qualifications, limitations and restrictions set forth in the Certificate of Designation (the “Certificate of Designation”) filed with the Secretary of State of the State of Delaware on March 28, 2013. The Certificate of Designation authorizes issuance of up to 4,500,000 3,750,000 750,000 9.99 4.99 The Certificate of Designation contains customary anti-dilution protection for proportional adjustments (e.g. stock splits). Upon approval of the full ratchet anti-dilution provisions on June 21, 2013, the warrants were reclassified as a derivative liability and recorded at fair value. This created a scenario for which the shares of Series F Preferred Stock were potentially convertible into more shares of common stock than authorized. Therefore, the Series F Preferred Stock was classified in temporary equity. Upon the expiration of the full ratchet anti-dilution provisions, the Company reclassified the Series F Preferred Stock and warrants to permanent stockholders’ equity following the stockholders vote. During the six months ended April 30, 2017, no shares of Series F Preferred Stock were converted to common shares. Dividends on the Series F Preferred Stock accrue at an annual rate of 5.0 2013 Fortress Credit Agreement On July 22, 2013, the Company issued warrants to purchase 72,727 41.25 0.2019 41.25 2 87,410 The Fortress warrants will expire on the seventh anniversary of the effective date of the Fortress transactions. 2014 Private Placement On March 31, 2014, the Company sold 99,331 45.13 4.5 49,666 49.00 0.2 49.00 59,693 2015 Common Stock Offering On January 27, 2015, the Company sold 153,587 46.00 7.1 82,938 55.20 1.1 0.2019 55.20 99,683 2015 Common Stock Rights Offering On July 28, 2015, the Company closed a subscription rights offering for the Company’s common stock (the “2015 Common Stock Rights Offering”).

Preferred Stock Rights [Abstract]
Preferred Stock Rights Disclosure [Text Block]	10. PREFERRED STOCK RIGHTS On May 23, 2014, the Company’s Board of Directors adopted a tax benefit preservation plan (the “Plan”). The Plan is intended to diminish the risk that the Company’s ability to use net operating loss carryforwards to reduce future federal income tax obligations may become substantially limited due to an “ownership change,” as defined in Section 382 of the Internal Revenue Code. The Board of Directors authorized and declared a dividend distribution of one right for each outstanding share of common stock, par value $0.001 per share, and Series F Preferred Stock, par value $0.001 per share, of the Company to stockholders of record as of the close of business on June 4, 2014. to purchase from the Company one one-thousandth of a share of Series G Participating Preferred Stock, 0.001 14.00 The rights will become exercisable following (i) the 10th business day (or such later date as may be determined by the Board of Directors) after the public announcement that an acquiring person has acquired beneficial ownership of 4.99 In addition, upon the occurrence of certain events, the exercise price of the rights would be adjusted and holders of the rights (other than rights owned by an acquiring person or group) would be entitled to purchase common stock at approximately half of market value. Given the potential adjustment of the exercise price of the rights, the rights could cause substantial dilution to a person or group that acquires 4.99% or more of the Company’s common stock on terms not approved by the Company’s Board of Directors. No rights were exercisable at April 30, 2017. There is no impact to the Company's financial results as a result of the adoption of the Plan for the six months ended April 30, 2017 or 2016.

ORGANIZATION AND BASIS OF PRE16

ORGANIZATION AND BASIS OF PRESENTATION (Policies)	6 Months Ended
	Apr. 30, 2017
Organization, Consolidation and Presentation Of Financial Statements [Abstract]
Consolidation, Policy [Policy Text Block]	Principles of Consolidation and Presentation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany transactions have been eliminated in consolidation. The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Company has accumulated significant losses as it developed its past products. Our operations are funded by cash and cash equivalents, as well as from revenue provided by IP licensing, royalties and other revenue. We may also generate revenue from other sources as described in Liquidity and Capital Resources, including without limitation, through obtaining a favorable judgment or settlement in our ongoing litigation concerning infringement of our intellectual property, successfully monetizing all or a portion of the non-‘972 patents, or pursuing other strategic opportunities to generate revenue. If we are not able to obtain additional sources of revenue through these or alternative means, the Company may not have sufficient funds to continue to operate the business. These conditions raise substantial doubt about the Company’s ability to continue as a going concern. These financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might be necessary should the Company be unable to continue as a going concern for a reasonable period of time. The investment in KIP CR P1 LP (which we refer to as the “partnership”) of which the Company is a limited partner and of which an affiliate of Fortress Investment Group (“Fortress”) is the general partner, is accounted for using the equity method. The current investment balance is nominal at April 30, 2017.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of the consolidated financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates, and such differences may be material to the consolidated financial statements.
Reclassification, Policy [Policy Text Block]	Reclassification Certain prior period amounts have been reclassified to conform to the current period presentation. The reclassification includes assets, liabilities, and certain expenses in sales and marketing, research and development, and general and administrative related to discontinued operations. The amounts for the prior periods have been reclassified to be consistent with the current period presentation and have no impact on previously reported financials.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents, Restricted Cash Cash and cash equivalents consist of cash on deposit and highly liquid investments with original maturities of 90 days or less at date of purchase. While the Company’s cash and cash equivalents are on deposit with high quality FDIC and Association of German Banks insured financial institutions, at times such deposits exceed insured limits. As of April 30, 2017, total uninsured deposits were $ 2.1 Restricted cash amounted to $ 0.6
Revenue Stream Sale [Policy Text Block]	IP Revenue Stream Sale On October 30, 2015, the Company entered into an agreement with TQ Zeta LLC, an affiliate of Techquity, and Intrepidus Holdings LLC (collectively, “Techquity”), pursuant to which Techquity will share in the revenue generated from the ‘972 patent litigation. For consideration of $ 10.0 52 20 40 20 100 12 100 0.9 3.3 0.6
Earnings Per Share, Policy [Policy Text Block]	Computation of Net Loss Per Share Basic loss per share is computed by dividing net loss available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share is computed by giving effect to all dilutive potential common shares that were outstanding during the period. Basic earnings per share excludes the dilutive effect of common stock equivalents such as stock options and warrants, while earnings per share, assuming dilution, includes such dilutive effects. Future weighted-average shares outstanding calculations will be impacted by the following factors, among others: (i) the ongoing issuance of common stock associated with stock option and warrant exercises; (ii) any fluctuations in the Company’s stock price, which could cause changes in the number of common stock equivalents included in the earnings per share, assuming dilution computation; and (iii) the issuance of common stock to effect business combinations should the Company enter into such transactions. The Company has excluded all outstanding common stock equivalents from the calculation of diluted net loss per share because all such common stock equivalents are antidilutive for all periods presented. The total number of common stock equivalents excluded from the diluted net loss per common share calculation was 3,234,495 3,150,497 368,765 2,591,257 274,473 Net loss available to common stockholders is calculated by deducting from net loss, preferred dividends paid and accrued of $ 136,000 129,000
New Accounting Pronouncements, Policy [Policy Text Block]	Recently Issued Accounting Pronouncements In August 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-15 requiring management to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern, which is currently performed by the external auditors. Management will be required to perform this assessment for both interim and annual reporting periods and must make certain disclosures if it concludes that substantial doubt exists. This ASU is effective for annual periods, and interim periods within those annual periods, beginning on or after December 15, 2016. The adoption of this guidance is not expected to have a material effect on our financial statements. In March 2016, the FASB issued ASU 2016-09 amending several aspects of share-based payment accounting. This guidance requires all excess tax benefits and tax deficiencies to be recorded in the income statement when the awards vest or are settled, with prospective application required. The guidance also changes the classification of such tax benefits or tax deficiencies on the statement of cash flows from a financing activity to an operating activity, with retrospective or prospective application allowed. Additionally, the guidance requires the classification of employee taxes paid when an employer withholds shares for tax-withholding purposes as a financing activity on the statement of cash flows, with retrospective application required. This ASU is effective for annual periods, and interim periods after those annual periods, beginning after December 15, 2016. Early adoption is permitted. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements and related disclosures.
