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.

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.

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.

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.
