	1.            Organization
	Comarco, Inc., through its wholly-owned subsidiary Comarco Wireless Technologies, Inc. (collectively, “we,” “our,” “Comarco,” “us,” or the “Company”), is a developer and designer of innovative technologies and intellectual property currently used in power adapters to power and charge battery powered devices such as laptop computers, tablets, smart phones and readers. Our operations consist solely of the operations of Comarco Wireless Technologies, Inc. (“CWT”), which was incorporated in the state of Delaware in September 1993. Comarco, Inc. was incorporated in California in 1960 and its common stock has been publicly traded since 1971 when it was spun-off from Genge Industries, Inc.
	Our business has historically targeted the needs of today’s mobile culture by providing innovative charging solutions for the myriad of battery powered devices used by nearly all consumers today. Our innovative technology allows the consumer to charge multiple devices from a single charger, eliminating the need to carry multiple chargers while traveling. This technology was developed by Comarco and we own an extensive patent portfolio related to this technology. Our patent portfolio is the result of years of research and development to provide charging solutions. During the current fiscal year, we have expanded our patent portfolio, while concurrently exploring other ways to capitalize on our patent portfolio.
	Substantially all of our recent revenue has been derived from a single customer, Lenovo Information Products Co., Ltd. (“Lenovo”). However, as previously announced, Lenovo has terminated its relationship with us (see Note 2 and Note 6). We completed our final shipment of product to Lenovo during the third quarter ended October 31, 2013 and anticipate that we will generate no or de minimus revenue in our fourth quarter ending January 31, 2014. We have effectively ceased traditional operations and are now primarily focused on potentially realizing value from our ongoing litigation matters (see Note 2 and Note 11) and exploring opportunities to expand, protect, and monetize our patent portfolio, including through the potential sale or licensing of our patent portfolio. Regardless of whether we generate significant capital infusions from litigation or from a sale or license of our patent portfolio, we may need to obtain additional debt and/or equity financing to meet our working capital needs. There is no assurance that we will prevail in our litigation, succeed in the sale or licensing of our patent portfolio or raise additional debt and/or equity financing and if we are not successful doing so, we may have to evaluate other alternatives or partially, or entirely, cease our operations. We currently have three employees, two executive officers and an accountant.

Going Concern [Text Block]	'
	2.            Current Developments, Future Operations, Liquidity and Capital Resources
	We have experienced substantial operating losses for the nine months ended October 31, 2013 and 2012 totaling $1.7 million and $1.8 million, respectively. The condensed consolidated financial statements have been prepared assuming that we will continue to operate as a going concern, which contemplates that we will realize our assets and satisfy our liabilities and commitments in the ordinary course of business. Our consolidated financial statements do not reflect any adjustments related to the outcome of this uncertainty. Our future is highly dependent on our ability to successfully resolve our current litigation, capitalize on our portfolio of patents, generate positive cash flows and obtain borrowings or raise capital to meet our liquidity needs.
	Our business during fiscal year 2013 and 2014 to date was almost entirely driven by sales of our products to Lenovo. However, as previously announced in a Form 8-K filed with the Securities and Exchange Commission (“SEC”) on August 22, 2013, Lenovo notified us of their intention to cease offering Comarco’s Constellation product, the power adapter Comarco designed and developed for Lenovo, to its corporate clients. We completed shipping product to Lenovo during our third fiscal quarter. As a result of this decision by Lenovo, we anticipate that we will generate no or de minimus revenue in our fourth fiscal quarter ending January 31, 2014. The loss of Lenovo will have a material adverse impact on our future results of operations. We have reduced and/or eliminated certain operating expenses to minimize future losses and cash burn and will continue our efforts in this regard. Our near term objectives include an orderly wind-down of the Lenovo relationship including collection of accounts receivable balances and a focus on preserving our ability to conclude our ongoing litigation with Chicony Power Technology, Co. Ltd. (“Chicony”). (See Note 11 for a description of the Chicony litigation).
	A positive outcome in our ongoing litigation with Chicony and ACCO Brands USA LLC and its Kensington Computer Products Group division (collectively “Kensington”), described in Note 11, if such an outcome were realized, could not only reduce our accumulated deficit, but could also provide us with a cash infusion. Conversely, a negative outcome or prolonged resolution to our ongoing litigation with either Chicony or Kensington could negatively impact our financial condition and we may not be able to continue as a going concern. However, the outcome of our ongoing litigation matters is not determinable as of the date of filing this report.
	Our extensive patent portfolio covering key technical aspects of our products could potentially generate a future revenue stream based upon royalties paid to us by others for the use of some or all of our patents in third party products. We are currently exploring opportunities to expand, protect, and monetize our patent portfolio, including through the sale or licensing of our patent portfolio.
	We had negative working capital totaling approximately $6.4 million at October 31, 2013, of which $2.8 million relates to the fair value of derivative liabilities. In order for us to conduct our business for the next twelve months, to continue operations thereafter and to be able to discharge our liabilities and commitments in the normal course of business, we must prevail in our current litigation against Chicony and/or Kensington, raise additional funds, through the sale or licensing of our patent portfolio, or obtain additional debt and/or equity financing to meet our working capital needs. There is no assurance that we will prevail in our litigation against Chicony and/or Kensington, succeed in the sale or licensing of our patent portfolio or raise additional financing and if we are not successful doing so, we may have to evaluate other alternatives or partially, or entirely, cease our operations.
	These uncertainties raise substantial doubt about our ability to continue as a going concern. If we become unable to continue as a going concern, we may have to liquidate our assets, and might realize significantly less than the values at which they are carried on our financial statements, and shareholders may lose all or part of their investment in our common stock. The condensed consolidated financial statements do not reflect any adjustments related to the outcome of this uncertainty.

Accounting Policies [Abstract]	'
Significant Accounting Policies [Text Block]	'
	3.            Summary of Significant Accounting Policies
	The summary of our significant accounting policies presented below is designed to assist the reader in understanding our condensed consolidated financial statements.
	Basis of Presentation
	The accompanying condensed consolidated balance sheet as of January 31, 2013, which has been derived from our audited financial statements, and our unaudited interim condensed consolidated financial statements as of October 31, 2013 included herein have been prepared without audit in accordance with accounting principles generally accepted in the United States of America for interim information and with the instructions for Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. The Company believes that the disclosures are adequate to make the information presented not misleading when read in conjunction with the audited consolidated financial statements included in the Company’s annual report on Form 10-K for the year ended January 31, 2013. The accounting policies followed by the Company are set forth in Note 2 to the Company’s audited financial statements included in its Form 10-K for its fiscal year ended January 31, 2013 (the “2013 10-K”), which was filed with the SEC on April 30, 2013 and amended by Amendment No. 1 on Form 10-K/A filed with the SEC on May 31, 2013. The unaudited interim condensed consolidated financial information presented herein reflects all adjustments, consisting only of normal recurring accruals, which are, in the opinion of management, necessary for a fair presentation of the consolidated results for the interim periods presented. The consolidated results for the three and nine months ended October 31, 2013 are not necessarily indicative of the results to be expected for the fiscal year ending January 31, 2014.
	Cash and Cash Equivalents
	All highly liquid investments with original maturity dates of three months or less when acquired are classified as cash and cash equivalents. The fair value of cash and cash equivalents approximates the amounts shown in the unaudited interim condensed consolidated financial statements. Cash and cash equivalents are generally maintained in uninsured accounts, typically Eurodollar deposits with daily liquidity, which are subject to investment risk including possible loss of principal invested. We have not historically suffered losses relating to cash and cash equivalents.
	Principles of Consolidation
	The unaudited interim condensed consolidated financial statements of the Company include the accounts of Comarco, Inc. and CWT, its wholly owned subsidiary. All material intercompany balances, transactions, and profits and losses have been eliminated.
	Accounts Receivable Due from Customers
	We offer unsecured credit terms to customers and perform ongoing credit evaluations of our customers. Accounts receivable balances result primarily from the timing of remittance payments by these customers to the Company. Accounts receivable are stated net of an allowance for doubtful accounts. Management develops its estimate of this reserve based upon specific identification of account balances that have indications of uncertainty of collection. Indications of uncertainty of collections may include the customer’s inability to pay, customer dissatisfaction, or other factors. Significant management judgments and estimates must be made and used in connection with establishing the allowance for doubtful accounts in any accounting period. Material differences may result in the amount and timing of our losses for any period if management made different judgments or utilized different estimates. Historically, such losses have been within management’s expectations and the reserves established. We do not anticipate any collection issues with the balance currently due from Lenovo.
	Accounts Receivable Due from Suppliers
	Historically, we were able to source components locally that we would later sell to our contract manufacturers (“CMs”), who build the finished goods, and other suppliers. This was especially the case when new products were initially introduced into production. Sales to our contract manufacturers and other suppliers are excluded from revenue and are recorded as a reduction to cost of revenue. During fiscal 2013, our relationship with Power System Technologies, Ltd. (“Power,” formerly Flextronics Electronics), the CM who built our Constellation product for Lenovo through the end of the third quarter of fiscal 2014 changed and we began procuring all of the component parts in the bill of material. We expect to offset the receivables due from suppliers from amounts we owe these suppliers, in the event we no longer receive cash payments.
	Restricted Cash
	Our restricted cash balances are secured by separate bank accounts and represent i) a $77,000 letter of credit that serves as the security deposit for our corporate office lease and ii) $5,000 which serves as collateral for credit card chargebacks associated with our internet website.
	Use of Estimates
	The preparation of unaudited interim condensed consolidated financial statements in conformity with GAAP 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 date of the unaudited interim condensed consolidated financial statements and the reported amounts of revenue and expenses during the period reported. Actual results could materially differ from those estimates.
	Certain accounting principles require subjective and complex judgments to be used in the preparation of financial statements. Accordingly, a different financial presentation could result depending on the judgments, estimates, or assumptions that are used. Such estimates and assumptions include, but are not specifically limited to, those required in the valuation of long-lived assets, allowance for doubtful accounts, reserves for inventory obsolescence, reserves for estimated warranty costs, valuation allowances for deferred tax assets, valuation of derivative liabilities and determination of stock-based compensation.
	Reclassifications
	Certain prior period balances have been reclassified to conform to the current period presentation. The reclassifications have no effect on previously reported results of operations or accumulated deficit.
	Impairment or Disposal of Long-lived Assets
	We review our long-lived assets for impairment whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. If the cost basis of a long-lived asset is greater than the projected future undiscounted net cash flows from such asset (excluding interest), an impairment loss is recognized. Impairment losses are calculated as the difference between the cost basis of an asset and its estimated fair value. We recognized impairment charges during the three months ended October 31, 2013 totaling approximately $60,000, which relates to the write-off of all tooling and equipment located at our various contract manufacturer locations in Asia, consistent with the cessation of manufacture of products for our customer Lenovo (see Note 2). Additionally, we sold fully depreciated engineering equipment for $28,000 in cash during the fiscal quarter ended October 31, 2013.
	Derivative Liabilities
	A derivative is an instrument whose value is “derived” from an underlying instrument or index such as a future, forward, swap, option contract, or other financial instrument with similar characteristics, including certain derivative instruments embedded in other contracts and for hedging activities. As a matter of policy, the Company does not invest in separable financial derivatives or engage in hedging transactions. However, the Company has entered into certain financing transactions in fiscal 2013 and fiscal 2014 that involve financial equity instruments containing certain features that have resulted in the instruments being deemed derivatives. The Company may engage in other similar complex financing transactions in the future, but not with the intention to enter into derivative instruments. Derivatives are measured at fair value using the Monte Carlo simulation pricing model and marked to market through earnings. However, such new and/or complex instruments may have immature or limited markets. As a result, the pricing models used for valuation of derivatives often incorporate significant estimates and assumptions. Changes in these subjective assumptions can materially affect the estimate of the fair value of derivative liabilities and, consequently, the related amount recognized as loss due to change in fair value of derivative liabilities on the condensed consolidated statement of operations. Furthermore, depending on the terms of a derivative, the valuation of derivatives may be removed from the financial statements upon exercise or conversion of the underlying instrument into some other security.
	We evaluate free-standing derivative instruments to properly classify such instruments within shareholders’ equity or as liabilities in our financial statements. Our policy is to settle instruments indexed to our common shares on a first-in-first-out basis.
	The classification of a derivative instrument is reassessed at each balance sheet date. If the classification changes as a result of events during a reporting period, the instrument is reclassified as of the date of the event that caused the reclassification. There is no limit on the number of times a contract may be reclassified.
	During the second quarter of fiscal 2013, we adopted the guidance, as codified in Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 815-40, Derivatives and Hedging, Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company’s Own Stock, that requires us to apply a two-step model in determining whether a financial instrument or an embedded feature is indexed to our own stock and thus enables it to qualify for equity classification. The warrants previously issued to Broadwood Partners, L.P. (“Broadwood”) contain provisions that adjust the exercise price in the event of certain dilutive issuance of our securities. Accordingly, the Company considered the warrants to be subject to price protection and classified them as derivative liabilities at the date of issuance with a fair value of $1.3 million and a corresponding discount to the underlying loan payable.
	Additionally, during the first quarter of fiscal 2014, we entered into a Loan Agreement with Elkhorn Partners Limited Partnership (“Elkhorn”) which contains convertible provisions that allow Elkhorn to convert the loan into common stock. The conversion price may be adjusted in the event of certain dilutive issuance of our securities. Accordingly, the Company considered the convertible debt to be subject to price protection and created a discount to the underlying loan payable and classified that value as derivative liabilities at the date of issuance with a fair value of $0.6 million (see Notes 9 and 10).
	Fair Value of Financial Instruments
	Our financial instruments include cash and cash equivalents, accounts receivable due from customers and suppliers, accounts payable, accrued liabilities, convertible debt and derivative liabilities. The carrying amount of cash and cash equivalents, accounts receivable due from customers and suppliers, accounts payable, and accrued liabilities are considered to be representative of their respective fair values due to the short-term nature of those instruments. The carrying amount of our convertible debt, net of discount, approximates fair value since the loan balance is derived from the valuation of the derivative liabilities. The fair value of the derivative liabilities, which are comprised of the warrants issued/issuable to Broadwood, as well as the estimated value of the conversion feature of the Elkhorn loan, at October 31, 2013 was $2.8 million. Derivative liabilities are reported at their estimated fair value, with changes in fair value being reported in current period results of operations.
	Legal expense classification
	Our legal expenses are classified in either selling, general, and administrative expenses or engineering and support expenses depending on the nature of the legal expense. All legal expenses incurred related to our intellectual property, including associated litigation expense and maintenance of our patent portfolio, are included in engineering and support expenses in our condensed consolidated statement of operations. Legal expenses included in engineering and support expenses for the three and nine months ended October 31, 2013 totaled $34,000 and $311,000, respectively. Legal expenses included in engineering and support expenses for the three and nine months ended October 31, 2012 totaled $423,000 and $1.2 million, respectively. The decreases in the current year expenses relate primarily to changing legal representation for our ongoing intellectual property infringement and enforcement litigation and our entry into an alternative professional fee arrangement in the third quarter of fiscal 2014 related to such representation.
	All other legal expenses, including all other litigation expense and public company legal expense are included in selling, general, and administrative expenses in our condensed consolidated statement of operations. Legal expenses included in selling, general, and administrative expenses for the three and nine months ended October 31, 2013 totaled a credit/reversal of $84,000 and expense of $449,000, respectively. Legal expenses included in selling, general, and administrative expenses for the three and nine months ended October 31, 2012 totaled $303,000 and $684,000, respectively. The decrease in the current fiscal year expenses relates to the fact that in the third quarter we entered into an agreement with our insurance carrier and received a one-time, lump sum payment for defense costs related to our Chicony litigation. Additionally, in the third quarter of fiscal 2014, we entered an alternative fee arrangement with our legal counsel representing us in the Chicony matter.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]	'
Disclosure of Compensation Related Costs, Share-based Payments [Text Block]	'
	4.            Stock-Based Compensation
	We grant stock awards for a fixed number of shares to employees, consultants, and directors pursuant to the Company’s shareholder-approved equity incentive plans.
	We account for stock-based compensation using the modified prospective method, which requires measurement of compensation cost for all stock awards at fair value on date of grant and recognition of compensation over the service period for awards expected to vest. The fair value of stock options is determined using a Lattice Binomial model for options with performance-based vesting tied to the Company’s stock price and the Black-Scholes valuation model for options with ratable term vesting. Both the Lattice Binomial and Black-Scholes valuation models require the input of subjective assumptions. These assumptions include estimating the length of time optionees will retain their vested stock options before exercising them (the “expected term”), the estimated volatility of our common stock price over the expected term, and the number of awards that will ultimately not complete their vesting requirements (“forfeitures”). Changes in these subjective assumptions can materially affect the estimate of fair value of stock-based compensation and, consequently, the related amount recognized as an expense on the consolidated statements of operations. As required under applicable accounting rules, we review our valuation assumptions at each grant date and, as a result, we are likely to change our valuation assumptions used to value stock-based awards granted in future periods. The values derived from using either the Lattice Binomial or the Black-Scholes model are recognized as an expense over the vesting period, net of estimated forfeitures. The estimation of stock awards that will ultimately vest requires significant judgment. Actual results, and future changes in estimates, may differ from our current estimates.
	The compensation expense recognized is summarized in the table below (in thousands except per share amounts):
			Three Months Ended						Nine Months Ended
			October 31,						October 31,
			2013			2012			2013			2012
	Total stock-based compensation expense		$	18		$	39		$	71		$	115
	Impact on basic and diluted earnings per share		$	0		$	0		$	0		$	0.01
	The total compensation cost related to nonvested awards not yet recognized is approximately $76,000, which will be expensed over a weighted average remaining life of 17.8 months.
	During the three and nine months ended October 31, 2013, no stock options were granted and 420,000 shares of restricted stock were granted. During the three months ended October 31, 2012, 465,000 stock options were granted and no restricted stock was granted. During the nine months ended October 31, 2012, 300,000 restricted stock units were granted and 465,000 stock options were granted. The fair value of the restricted stock granted during the nine months ended October 31, 2013 was estimated using the stock price on the date of the grant of $0.18 and a forfeiture rate of 8.2 percent. The fair value of the restricted stock units granted during the nine months ended October 31, 2012 was estimated using the stock price on the date of the grant of $0.16 and a forfeiture rate of 10.6 percent.
	The fair value of the 465,000 options granted under our stock option plans during the first three quarters of fiscal 2013 was estimated on the date of grant using the following weighted average assumptions:
			Year-to-date
			31-Oct-12
	Weighted average risk-free interest rate			0.7	%
	Expected life (in years)			5.5
	Expected stock volatility			121	%
	Dividend yield		None
	Expected forfeitures			8.2	%
	The Company’s former employee stock option plan (the “Employee Plan”) expired during May 2005. As a result, no new options could be granted under the plan thereafter. This plan provided for the issuance of up to 825,000 shares of common stock. During December 2005, the Board of Directors approved and adopted the Company’s 2005 Equity Incentive Plan (the “2005 Plan”) covering 450,000 shares of common stock. The 2005 Plan was approved by the Company’s shareholders at its annual shareholders’ meeting in June 2006, and subsequently amended at its annual shareholders’ meeting in June 2008 to increase the number of shares issuable under the plan from 450,000 to 1,100,000 shares. In July 2011, the Company’s shareholders approved the 2011 Equity Incentive Plan (the “2011” Plan) covering 750,000 shares of common stock.
	Under both the 2011 and 2005 Plan, the Company may grant stock options, stock appreciation rights, restricted stock, restricted stock units, and performance based awards to employees, consultants and directors. Under all plans, awards vest or become exercisable in installments determined by the compensation committee of the Company’s Board of Directors; however, under the 2005 Plan no option may be exercised prior to one year following the grant of the option. The options granted under the Employee Plan expire as determined by the committee, but no later than ten years and one week after the date of grant (five years for 10 percent shareholders). The options granted under the 2011 and 2005 Plan expire as determined by the committee, but no later than ten years after the date of grant (five years for 10 percent shareholders).
	In the aggregate, Comarco has stock-based compensation plans under which outside directors, consultants, and employees are eligible to receive stock options and other equity-based awards. The stock option plans provide that officers, key employees, directors and consultants may be granted options to purchase up to 2,675,000 shares of common stock of the Company at not less than 100 percent of the fair market value at the date of grant, unless the grantee is a 10 percent shareholder of the Company, in which case the price must not be less than 110 percent of the fair market value.

	5.            Earnings (Loss) Per Share
	The Company calculates basic earnings (loss) per share by dividing net income (loss) by the weighted-average number of common shares outstanding during the reporting period. Diluted earnings (loss) per share reflects the effects of potentially dilutive securities. Since the Company incurred a net loss for the nine months ended October 31, 2013 and the three and nine months ended October 31, 2012, basic and diluted loss per share for those periods were the same because the inclusion of dilutive potential common shares related to outstanding stock awards in the calculation would have been antidilutive.
	Potential common shares of 720,000 relating to outstanding stock awards to directors and employees have been excluded from diluted weighted average common shares for the nine months ended October 31, 2013, as the effect would have been antidilutive. Additionally, for the nine months ended October 31, 2013, the 1,704,546 outstanding warrants issued to Broadwood would have been anti-dilutive. Similarly, potential common shares of 330,000 relating to outstanding stock awards to directors and employees have been excluded from diluted weighted average common shares for the three and nine months ended October 31, 2012, as the effect would have been antidilutive.
	The following table presents reconciliations of the numerators and denominators of the basic and diluted earnings (loss) per share computations for net income (loss). In the tables below, “Net income or loss” represents the numerator and “Shares” represents the denominator (in thousands, except per share amounts):

	Substantially all of the Company’s revenue is derived from a single customer, Lenovo. As discussed in Note 2 above, Lenovo notified us of their intention to cease offering Comarco’s product to its customers. We shipped approximately 20,000 of our Constellation units to Lenovo and 11,000 field replacement units to Lenovo affiliates during our third fiscal quarter, and we have no further orders from Lenovo or their affiliates. The loss of Lenovo will have a material adverse impact on our future revenues and results of operations.

	Zheng Ge Electrical Co., Ltd.		122	19	%		122	11	%
		$	595	94	%	$	1,130	98	%
	The decrease in the receivables due from Power Systems Technologies, Inc. (“Power,” formerly Flextronics Electronics) is driven by an increased frequency in payment in early fiscal 2014 coupled with a reduction in component sales late in the third quarter of fiscal 2014 in conjunction with the final sales to Lenovo, which has caused a drop in the receivable balance as of October 31, 2013.
	Zheng Ge Electrical Co., Ltd. (“Zheng Ge”) was a tip supplier for one of our prior product offerings (referred to as the Bronx product), which was subject to a recall during 2010. We previously sourced some of the component parts that Zheng Ge used in the manufacture of the tips. We ceased paying Zheng Ge during the course of the product recall while we investigated the manufacturing defect that caused the recall and, likewise, Zheng Ge ceased paying us.
	We expect to offset the receivables due from Power and Zheng Ge from amounts owed, which are included in accrued liabilities in our consolidated balance sheet. Subsequent to the final delivery and sales of our Constellation product to Lenovo, we have attempted to work with Power to collect the outstanding receivable balance, but to date Power has been non-responsive.
	The companies comprising 10 percent or more of our gross accounts payable at either October 31, 2013 or January 31, 2013 are listed below (in thousands, except percentages).
		31-Oct-13				31-Jan-13

		$	3,053	69	%	$	2,714	74	%
	Chicony was the manufacturer of the Bronx product, which was subject to a recall during 2010 and we are currently in litigation with Chicony (see Note 11). We have made no payments to this supplier during either fiscal 2014 or 2013. The outcome of such litigation is not determinable at this time and we do not know whether or not we will be obligated to pay this liability. If we prevail in this case, based upon our causes of action, it is likely we will be relieved of this liability. There is no assurance, however, as to the outcome of this litigation (see Note 11).
	Pillsbury Winthrop Shaw Pittman, LLP (“Pillsbury”) was our former legal counsel for the Kensington litigation as well as other patent and intellectual property matters (See Note 11). We have made no payments to Pillsbury during fiscal 2014.
	Historically, a significant portion of our inventory purchases had been derived from a limited number of contract manufacturers (“CM’s”) and other suppliers. However we ceased procuring inventory during the third quarter of fiscal 2014 in conjunction with the final manufacture and delivery of Constellation units to Lenovo.

	9.             Loan & Related Agreements
	As previously reported, on February 11, 2013, the Company and Elkhorn Partners Limited Partnership (“Elkhorn”), entered into a Secured Loan Agreement (the “Elkhorn Loan Agreement”) and a Stock Purchase Agreement (the “Elkhorn SPA”), and certain related agreements, which are described below (collectively, the “Elkhorn Agreements”). Pursuant to those Agreements, Elkhorn has made a $1.5 million senior secured loan to the Company with a maturity date of November 30, 2014 and has purchased a total of 6,250,000 shares of the Company’s common stock at a cash purchase price of $0.16 per share, generating an additional $1.0 million of cash for the Company. The average of the closing prices of the Company’s common stock in the over-the-counter market for the five trading days immediately preceding February 11, 2013 was $0.14 per share and, for the 29 trading days that began on January 2, 2013 and ended on February 8, 2013, was $0.158 per share. On February 11, 2013, the Company used approximately $2.1 million of the proceeds of $2.5 million from the Elkhorn Loan and the sale of the shares to Elkhorn to pay the entire principal amount of and all accrued interest on the Broadwood Loan.
	Secured Loan Agreement with Elkhorn Partners.
	The Elkhorn Loan, which is evidenced by a promissory note (the “Elkhorn Note”), issued by the Company to Elkhorn, bears interest at 7% for the first 12 months of the Loan, increasing to 8.5% thereafter and continuing until the Loan is paid in full. The Loan matures on November 30, 2014 (the “Maturity Date”); however, the Company has the right, at its option, to prepay the Elkhorn Loan, in whole or in part, without penalty or premium.
	The Elkhorn Loan Agreement provides that if and to the extent the Company does not pay the Elkhorn Loan in full by its Maturity Date, then, Elkhorn will have the right, at its option (but not the obligation), to convert the then unpaid balance of the Loan, in whole or in part, into shares of Company common stock at a conversion price of $0.25 per share. That conversion price is subject to possible adjustment on (i) certain sales of Company common stock at a price lower than $0.25 per share, (ii) stock splits of, stock dividends on and any reclassification of the Company’s outstanding shares, and (iii) certain mergers or reorganizations of the Company, as provided in Article III of the Elkhorn Loan Agreement. This conversion feature creates a derivative liability that is described in Note 10.
	The Elkhorn Loan Agreement contains customary representations and warranties of and affirmative and negative covenants on the part of the Company and CWT. The Agreement also provides that the Elkhorn Loan, together with accrued interest, will become immediately due and payable upon the occurrence of an Event of Default, which is defined in the Loan Agreement to include each of the following, among others: (i) a failure of the Company to pay the principal of or accrued interest on the Loan which continues unremedied for three calendar days (except that such grace period shall not apply to amounts due at the Maturity Date of the Loan), (ii) the Company or CWT commits a breach of any of their other material obligations under the Loan Agreement or under any of the Debt Related Agreements (described below) and the breach which remains uncured for a period ranging from 15 days to 30 days (depending on the nature of the breach) following receipt of notice of the breach from Elkhorn; (iii) any of the representations or warranties of the Company or CWT contained in the Loan Agreement prove to have been untrue or incorrect in any material respect, (iv) the Company or CWT fails to pay indebtedness, as such term is defined in the Elkhorn Loan Agreement, in the amount of $200,000 or more owed to any other creditor, (v) one or more judgments are entered against the Company or CWT in an aggregate amount of $200,000 or more, which are not satisfied, discharged, stayed or bonded against within the succeeding 30 days, and (vi) the filing by the Company of a voluntary petition in bankruptcy or the Company’s failure to obtain the dismissal, within 60 days, of an involuntary petition filed against it in bankruptcy, or a receiver or liquidator is appointed over, or an attachment is issued against a substantial part of the assets of the Company or CWT, which in either case remains undismissed for the succeeding thirty (30) days.
	Upon the occurrence and during the continuance of an Event of Default, interest on the Loan will accrue at the lesser of (i) 15% per annum or (ii) the highest rate permitted by applicable law.
	Debt Related Agreements. In connection with the Elkhorn Loan Agreement, the Company and CWT entered into a Security Agreement and the Company entered into a Pledge Agreement (collectively, the “Debt Related Agreements”) with Elkhorn to secure the payment and performance by the Company and CWT of their respective obligations under the Loan Agreement and the Debt Related Agreements. Set forth below is a summary of those Agreements.
	Security Agreement. As security for the performance of their respective obligations under the Elkhorn Loan Agreement and the Debt Related Agreements, the Company and CWT have entered into a security agreement (the “Security Agreement”) granting Elkhorn a first priority perfected security interest in all of their assets, including their intellectual property rights. The Security Agreement provides that, on the occurrence and during the continuance of an Event of Default, whether by the Company or CWT, Elkhorn will become entitled to take possession of and to sell the assets of the Company and CWT to the extent necessary to recover the amounts due Elkhorn under the Loan Agreement and any other amounts that may be due and payable to Elkhorn under any of the Debt Related Agreements.
	Pledge Agreement. As additional security for the payment and performance of its obligations under the Elkhorn Loan Agreement, the Company has entered into a Pledge Agreement (the “Pledge Agreement”) pursuant to which it has pledged and will deliver possession to Elkhorn of all of CWT’s outstanding shares. The Pledge Agreement provides, among other things, that upon the occurrence and during the continuance of an Event of Default, Elkhorn will become entitled to transfer the CWT shares into its name, to vote those shares and, subject to applicable securities laws, to sell those shares in order to recover amounts owed to it by the Company.
	Elkhorn Stock Purchase Agreement
	Concurrently with the Company’s entry into the Loan Agreement, the Company and Elkhorn entered into the Elkhorn SPA. Pursuant to that Agreement, the Company sold 6,250,000 shares of its common stock to Elkhorn at a price of $0.16 per share, resulting in an aggregate purchase price of $1.0 million. As noted above, that purchase price compares to an average per share closing price for Comarco’s shares of $0.14 during the five trading days immediately preceding the sale of the shares to Elkhorn, and an average per share closing price of $0.158 for the 29 trading days that that began on January 1, 2013 and ended on February 8, 2013.
	The purchase price of $0.16 per share paid by Elkhorn for those shares was determined by arms-length negotiations between Elkhorn and the members of a special committee of the Company’s Board of Directors, comprised of three of the directors who have no affiliation with Elkhorn and no financial interest, other than their interests solely as shareholders of the Company, in either the loan or share transactions with Elkhorn. That per share purchase price was determined based on a number of factors, including the Company’s inability, notwithstanding its best efforts, to raise additional capital from other prospective institutional investors during the six month term of the Broadwood Loan and the recent trading prices of the Company’s shares in the over-the-counter market.
	Senior Secured Six Month Term Loan Agreement with Broadwood Partners L.P. (“Broadwood”)
	The Company entered into a Senior Secured Six Month Term Loan Agreement dated July 27, 2012 (the “Loan Agreement”) with Broadwood, a significant shareholder of the Company.
	Pursuant to that Agreement, Broadwood made a $2,000,000 senior secured six month loan (the “Loan”) to the Company and to CWT, as co-borrower. The loan bore interest at 5% per annum, ranked senior in right of payment to all other indebtedness of the Company and was due and payable in full on January 28, 2013. The Company originally intended to repay the Loan and accrued interest from the $3.0 million in proceeds that was expected to be received from Broadwood in the fourth quarter of fiscal 2013, pursuant to the Broadwood Stock Purchase Agreement (“Broadwood SPA”). As consideration for the Loan and Broadwood’s entry into the SPA, on July 27, 2012 the Company issued stock purchase warrants (the “Warrants”) to Broadwood entitling it to purchase up to a total of 1,704,546 shares of the Company’s common stock (the “Warrant Shares”), at a price of $1.00 per Warrant Share, at any time through July 2020.
	On January 28, 2013, the maturity date of the loan, the Company was informed by Broadwood, that it was Broadwood’s position that one or more of the conditions precedent to its obligation to purchase the Company’s shares pursuant to the Broadwood SPA had not been satisfied and, as a result, Broadwood would not consummate that purchase and, therefore, the Company would have to repay the loan in cash. The Company’s position is that, contrary to Broadwood’s assertions, all of the conditions under the SPA had been satisfied, and Broadwood’s refusal to purchase 3,000,000 shares of Company common stock, at the price of $1.00 per share, constituted a material breach by Broadwood of its obligations under the Broadwood SPA. As a result, as of the date of filing this report, the Company has not issued any of the 1,000,000 Additional Warrant Shares to Broadwood and each party has reserved its rights under and with respect to the Broadwood SPA and the Broadwood Warrants.
	During the first quarter of fiscal 2014, the Company repaid the amounts outstanding under the Broadwood Loan Agreement in full from the Elkhorn proceeds described above.

	10.          Fair Value Measurements
	We follow FASB ASC 820, "Fair Value Measurements and Disclosures" (“ASC 820”) in connection with assets and liabilities measured at fair value on a recurring basis subsequent to initial recognition. The guidance applies to our derivative liabilities. We had no assets or liabilities measured at fair value on a non-recurring basis for any period reported.
	ASC 820 requires that assets and liabilities carried at fair value will be classified and disclosed in one of the following three categories. We measure the fair value of applicable financial and non-financial assets based on the following fair value hierarchy:
	Level 1: Quoted market prices in active markets for identical assets or liabilities.
	Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data.
	Level 3: Unobservable inputs that are not corroborated by market data.
	The hierarchy noted above requires us to minimize the use of unobservable inputs and to use observable market data, if available, when determining fair value.
	The fair value of our recorded derivative liabilities is determined based on unobservable inputs that are not corroborated by market data, which is a Level 3 classification. We record derivative liabilities on our balance sheet at fair value with changes in fair value recorded in our consolidated statements of operations.
	Our fair value measurements at the October 31, 2013 reporting date are classified based on the valuation technique level noted in the table below (in thousands):
	Description	October 31,		Quoted Prices		Significant Other Observable			Significant

	11.          Commitments and Contingencies
	Purchase Commitments with Suppliers
	The Company has historically issued purchase orders to its suppliers with delivery dates from four to six weeks from the purchase order date. In addition, the Company has typically provided significant suppliers with rolling six-month forecasts of material and finished goods requirements for planning and long-lead time parts procurement purposes only. The Company generally accepts delivery of materials pursuant to its purchase orders subject to various contract provisions that allow it to delay receipt of such order or allow it to cancel orders beyond certain agreed lead times. Such cancellations may or may not include cancellation costs payable by the Company. In the past, the Company has been required to take delivery of materials from its suppliers that were in excess of its requirements and the Company has previously recognized charges and expenses related to such excess material. In the third quarter of fiscal 2014, we began the process of cancelling purchase orders beyond the forecasted unit volume contained in Lenovo’s rolling forecast upon the receipt of their notification that it will cease purchasing our product (See Note 2).
	During the third quarter ended October 31, 2013, we recorded a charge to cost of revenue in the amount of $317,000 related to our remaining inventory balances, representing primarily component inventory in excess of requirements. We also shipped certain components to a liquidator in an attempt to salvage some economic value from these parts, but to date we have not recovered any amounts and expect such recoveries, if any, to be minor.
	Executive Severance Agreements
	The Company has severance compensation agreements with two executives, our Chief Executive Officer and Chief Accounting Officer. These agreements require the Company to pay these executives, in the event of certain terminations of employment following a change of control of the Company, up to the amount of their then current annual base salary and the amount equal to any bonus which the executive would have earned for the year in which the termination occurs plus the acceleration of unvested options.
	Although the contemplated sale of shares of common stock and the issuance of the Warrants and possible issuance of the Additional Warrant Shares by the Company to Broadwood (see Note 9) could result in a change of control for purposes of the severance compensation agreements, each of the executives who are parties to those agreements has waived their rights to receive payments under those agreements in the event that a change of control occurs as a result of the sale of shares and the issuance of Warrants and Additional Warrants to Broadwood.
	Additionally, as a result of the Company’s sale of the 6,250,000 shares of common stock to Elkhorn during the first quarter of fiscal 2014 (see Note 9), Elkhorn’s beneficial ownership of the Company increased from approximately 9% to approximately 47% of the Company’s outstanding voting stock as of December 12, 2013, making Elkhorn the Company’s largest shareholder and resulting in a change of control for purposes of the severance compensation agreements. Each of the executives who are parties to those agreements has waived their rights to receive payments under those agreements as a result of the change in Elkhorn’s beneficial ownership of the Company.
	Letter of Credit
	During the first quarter of fiscal 2010, the Company obtained a $77,000 letter of credit from Silicon Valley Bank (“SVB”) to allow for continuous and unlapsed compliance with a lease provision for the Company’s corporate offices. The letter of credit expires on August 1, 2014.
	Legal Proceedings and Contingencies
	On April 26, 2011, Chicony, the contract manufacturer of the Bronx product that was the subject of a product recall in 2010, filed a complaint against us for breach of contract, seeking payment of $1.2 million for the alleged non-payment by us of amounts alleged by Chicony to be due it for products purchased from it by the Company.  We denied liability and filed a cross-complaint on May 13, 2011 seeking the recovery of damages of $4.9 million caused by Chicony's failure to adhere to our technical specifications when manufacturing the Bronx product, which we believe resulted in the recall of the product. On May 23, 2012, Chicony filed its First Amended Complaint increasing the payment it is seeking from $1.2 million to $1.7 million based on alleged component parts it purchased for the Bronx product, but was unable to use in any other products thereafter. On April 16, 2013, the court approved our first-amended cross-complaint, which adds intentional interference to our complaint and increases the damages we seek to at least $15.0 million. In an effort to resolve this litigation before the previous trial date of April, 2013, we sent Chicony a settlement offer, which has since lapsed without response from Chicony. The trial began on October 21, 2013 and is currently expected to conclude by the end of January, 2014.
	The outcome of this matter is not determinable as of the date of the filing of this report. We have previously accrued $1.1 million for the possibility that we could incur a liability to Chicony should it prevail in the lawsuit.
	In July 2013, in response to our stated desire to have counsel appointed by us representing our consolidated interests across the entirety of our litigation with Chicony, we entered into discussions with our insurance carrier and on August 26, 2013 we entered into an agreement as a means to achieve our desired representation goal.
	Pursuant to the agreement, our insurance carrier paid one hundred percent of our defense costs and fifty percent of our expert fees related to the Chicony litigation through August 31, 2013 and we received a one-time, lump-sum payment in exchange for a mutual release and the assumption of sole financial responsibility for any expenses related to our ongoing Chicony litigation subsequent to August 31, 2013. As a result, a single law firm of our choosing now represents us on all matters concerning the Chicony litigation. Additionally, in the third quarter of fiscal 2014, we entered an alternative fee arrangement with our legal counsel representing us in the Chicony matter.
	On September 1, 2011, subsequent to receiving an infringement notification from us, ACCO Brands USA LLC and its Kensington Computer Products Group division (collectively “Kensington”) filed a lawsuit against us alleging that five of our patents relating to power technology are invalid and/or not infringed by products made and/or sold by Kensington. On February 29, 2012, we denied these claims and filed a cross-complaint alleging infringement by Kensington of each of these five patents. Efforts to resolve the dispute, by court ordered mediation, have been unsuccessful. A number of these patents are currently the subject of re-examination proceedings initiated by Kensington or other third parties. This matter is ongoing and the outcome is not determinable, however if we do not prevail we will likely not obtain a license agreement to earn future license revenue from products sold by Kensington. Conversely, should we prevail the Company may be awarded a royalty which would generate license revenue to the Company in the future. In the third quarter of fiscal 2014, we changed legal representation for our ongoing Kensington litigation and entered an alternative fee arrangement.
	On March 6, 2012, we filed a lawsuit against EDAC Power Electronics Co. Ltd (“EDAC”) for breach of contract seeking payment of $2.5 million for the failure to deliver goods ordered by us in the time, place, manner and price indicated by each purchase order. As previously reported, the parties entered into a Settlement Agreement on July 24, 2012, ending the litigation between the parties. The settlement involved no cash payments by either of the parties, but allowed us to recover previously incurred product and freight costs and to discharge net liabilities of $1.4 million from our consolidated balance sheet that would otherwise have been due to EDAC had it prevailed in the lawsuit. The settlement resulted in a decrease to cost of revenue of $1.4 million.
	In addition to the pending matters described above, we are, from time to time, involved in various legal proceedings incidental to the conduct of our business. We are unable to predict the ultimate outcome of these matters.

Accounting Policies [Abstract]	'
Basis of Accounting, Policy [Policy Text Block]	'
	Basis of Presentation
	The accompanying condensed consolidated balance sheet as of January 31, 2013, which has been derived from our audited financial statements, and our unaudited interim condensed consolidated financial statements as of October 31, 2013 included herein have been prepared without audit in accordance with accounting principles generally accepted in the United States of America for interim information and with the instructions for Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. The Company believes that the disclosures are adequate to make the information presented not misleading when read in conjunction with the audited consolidated financial statements included in the Company’s annual report on Form 10-K for the year ended January 31, 2013. The accounting policies followed by the Company are set forth in Note 2 to the Company’s audited financial statements included in its Form 10-K for its fiscal year ended January 31, 2013 (the “2013 10-K”), which was filed with the SEC on April 30, 2013 and amended by Amendment No. 1 on Form 10-K/A filed with the SEC on May 31, 2013. The unaudited interim condensed consolidated financial information presented herein reflects all adjustments, consisting only of normal recurring accruals, which are, in the opinion of management, necessary for a fair presentation of the consolidated results for the interim periods presented. The consolidated results for the three and nine months ended October 31, 2013 are not necessarily indicative of the results to be expected for the fiscal year ending January 31, 2014.
Cash and Cash Equivalents, Policy [Policy Text Block]	'
	Cash and Cash Equivalents
	All highly liquid investments with original maturity dates of three months or less when acquired are classified as cash and cash equivalents. The fair value of cash and cash equivalents approximates the amounts shown in the unaudited interim condensed consolidated financial statements. Cash and cash equivalents are generally maintained in uninsured accounts, typically Eurodollar deposits with daily liquidity, which are subject to investment risk including possible loss of principal invested. We have not historically suffered losses relating to cash and cash equivalents.
Consolidation, Policy [Policy Text Block]	'
	Principles of Consolidation
	The unaudited interim condensed consolidated financial statements of the Company include the accounts of Comarco, Inc. and CWT, its wholly owned subsidiary. All material intercompany balances, transactions, and profits and losses have been eliminated.
Accounts Receivable from Customers Policy Text Block	'Accounts Receivable Due from CustomersWe offer unsecured credit terms to customers and perform ongoing credit evaluations of our customers. Accounts receivable balances result primarily from the timing of remittance payments by these customers to the Company. Accounts receivable are stated net of an allowance for doubtful accounts. Management develops its estimate of this reserve based upon specific identification of account balances that have indications of uncertainty of collection. Indications of uncertainty of collections may include the customer's inability to pay, customer dissatisfaction, or other factors. Significant management judgments and estimates must be made and used in connection with establishing the allowance for doubtful accounts in any accounting period. Material differences may result in the amount and timing of our losses for any period if management made different judgments or utilized different estimates. Historically, such losses have been within management's expectations and the reserves established. We do not anticipate any collection issues with the balance currently due from Lenovo.
Accounts Receivable from Suppliers [Policy Text Block]	'Accounts Receivable Due from SuppliersHistorically, we were able to source components locally that we would later sell to our contract manufacturers ("CMs"), who build the finished goods, and other suppliers. This was especially the case when new products were initially introduced into production. Sales to our contract manufacturers and other suppliers are excluded from revenue and are recorded as a reduction to cost of revenue. During fiscal 2013, our relationship with Power System Technologies, Ltd. ("Power," formerly Flextronics Electronics), the CM who built our Constellation product for Lenovo through the end of the third quarter of fiscal 2014 changed and we began procuring all of the component parts in the bill of material. We expect to offset the receivables due from suppliers from amounts we owe these suppliers, in the event we no longer receive cash payments.
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block]	'
	Restricted Cash
	Our restricted cash balances are secured by separate bank accounts and represent i) a $77,000 letter of credit that serves as the security deposit for our corporate office lease and ii) $5,000 which serves as collateral for credit card chargebacks associated with our internet website.
Use of Estimates, Policy [Policy Text Block]	'
	Use of Estimates
	The preparation of unaudited interim condensed consolidated financial statements in conformity with GAAP 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 date of the unaudited interim condensed consolidated financial statements and the reported amounts of revenue and expenses during the period reported. Actual results could materially differ from those estimates.
	Certain accounting principles require subjective and complex judgments to be used in the preparation of financial statements. Accordingly, a different financial presentation could result depending on the judgments, estimates, or assumptions that are used. Such estimates and assumptions include, but are not specifically limited to, those required in the valuation of long-lived assets, allowance for doubtful accounts, reserves for inventory obsolescence, reserves for estimated warranty costs, valuation allowances for deferred tax assets, valuation of derivative liabilities and determination of stock-based compensation.
Reclassification, Policy [Policy Text Block]	'
	Reclassifications
	Certain prior period balances have been reclassified to conform to the current period presentation. The reclassifications have no effect on previously reported results of operations or accumulated deficit.
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]	'
	Impairment or Disposal of Long-lived Assets
	We review our long-lived assets for impairment whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. If the cost basis of a long-lived asset is greater than the projected future undiscounted net cash flows from such asset (excluding interest), an impairment loss is recognized. Impairment losses are calculated as the difference between the cost basis of an asset and its estimated fair value. We recognized impairment charges during the three months ended October 31, 2013 totaling approximately $60,000, which relates to the write-off of all tooling and equipment located at our various contract manufacturer locations in Asia, consistent with the cessation of manufacture of products for our customer Lenovo (see Note 2). Additionally, we sold fully depreciated engineering equipment for $28,000 in cash during the fiscal quarter ended October 31, 2013.
Derivatives, Policy [Policy Text Block]	'
	Derivative Liabilities
	A derivative is an instrument whose value is “derived” from an underlying instrument or index such as a future, forward, swap, option contract, or other financial instrument with similar characteristics, including certain derivative instruments embedded in other contracts and for hedging activities. As a matter of policy, the Company does not invest in separable financial derivatives or engage in hedging transactions. However, the Company has entered into certain financing transactions in fiscal 2013 and fiscal 2014 that involve financial equity instruments containing certain features that have resulted in the instruments being deemed derivatives. The Company may engage in other similar complex financing transactions in the future, but not with the intention to enter into derivative instruments. Derivatives are measured at fair value using the Monte Carlo simulation pricing model and marked to market through earnings. However, such new and/or complex instruments may have immature or limited markets. As a result, the pricing models used for valuation of derivatives often incorporate significant estimates and assumptions. Changes in these subjective assumptions can materially affect the estimate of the fair value of derivative liabilities and, consequently, the related amount recognized as loss due to change in fair value of derivative liabilities on the condensed consolidated statement of operations. Furthermore, depending on the terms of a derivative, the valuation of derivatives may be removed from the financial statements upon exercise or conversion of the underlying instrument into some other security.
	We evaluate free-standing derivative instruments to properly classify such instruments within shareholders’ equity or as liabilities in our financial statements. Our policy is to settle instruments indexed to our common shares on a first-in-first-out basis.
	The classification of a derivative instrument is reassessed at each balance sheet date. If the classification changes as a result of events during a reporting period, the instrument is reclassified as of the date of the event that caused the reclassification. There is no limit on the number of times a contract may be reclassified.
	During the second quarter of fiscal 2013, we adopted the guidance, as codified in Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 815-40, Derivatives and Hedging, Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company’s Own Stock, that requires us to apply a two-step model in determining whether a financial instrument or an embedded feature is indexed to our own stock and thus enables it to qualify for equity classification. The warrants previously issued to Broadwood Partners, L.P. (“Broadwood”) contain provisions that adjust the exercise price in the event of certain dilutive issuance of our securities. Accordingly, the Company considered the warrants to be subject to price protection and classified them as derivative liabilities at the date of issuance with a fair value of $1.3 million and a corresponding discount to the underlying loan payable.
	Additionally, during the first quarter of fiscal 2014, we entered into a Loan Agreement with Elkhorn Partners Limited Partnership (“Elkhorn”) which contains convertible provisions that allow Elkhorn to convert the loan into common stock. The conversion price may be adjusted in the event of certain dilutive issuance of our securities. Accordingly, the Company considered the convertible debt to be subject to price protection and created a discount to the underlying loan payable and classified that value as derivative liabilities at the date of issuance with a fair value of $0.6 million (see Notes 9 and 10).
Fair Value of Financial Instruments, Policy [Policy Text Block]	'
	Fair Value of Financial Instruments
	Our financial instruments include cash and cash equivalents, accounts receivable due from customers and suppliers, accounts payable, accrued liabilities, convertible debt and derivative liabilities. The carrying amount of cash and cash equivalents, accounts receivable due from customers and suppliers, accounts payable, and accrued liabilities are considered to be representative of their respective fair values due to the short-term nature of those instruments. The carrying amount of our convertible debt, net of discount, approximates fair value since the loan balance is derived from the valuation of the derivative liabilities. The fair value of the derivative liabilities, which are comprised of the warrants issued/issuable to Broadwood, as well as the estimated value of the conversion feature of the Elkhorn loan, at October 31, 2013 was $2.8 million. Derivative liabilities are reported at their estimated fair value, with changes in fair value being reported in current period results of operations.
Selling, General and Administrative Expenses, Policy [Policy Text Block]	'
	Legal expense classification
	Our legal expenses are classified in either selling, general, and administrative expenses or engineering and support expenses depending on the nature of the legal expense. All legal expenses incurred related to our intellectual property, including associated litigation expense and maintenance of our patent portfolio, are included in engineering and support expenses in our condensed consolidated statement of operations. Legal expenses included in engineering and support expenses for the three and nine months ended October 31, 2013 totaled $34,000 and $311,000, respectively. Legal expenses included in engineering and support expenses for the three and nine months ended October 31, 2012 totaled $423,000 and $1.2 million, respectively. The decreases in the current year expenses relate primarily to changing legal representation for our ongoing intellectual property infringement and enforcement litigation and our entry into an alternative professional fee arrangement in the third quarter of fiscal 2014 related to such representation.
	All other legal expenses, including all other litigation expense and public company legal expense are included in selling, general, and administrative expenses in our condensed consolidated statement of operations. Legal expenses included in selling, general, and administrative expenses for the three and nine months ended October 31, 2013 totaled a credit/reversal of $84,000 and expense of $449,000, respectively. Legal expenses included in selling, general, and administrative expenses for the three and nine months ended October 31, 2012 totaled $303,000 and $684,000, respectively. The decrease in the current fiscal year expenses relates to the fact that in the third quarter we entered into an agreement with our insurance carrier and received a one-time, lump sum payment for defense costs related to our Chicony litigation. Additionally, in the third quarter of fiscal 2014, we entered an alternative fee arrangement with our legal counsel representing us in the Chicony matter.
