Patents

Patent-picture-resizedWe have a policy of seeking to protect our intellectual property through patents, license agreements, trademark registrations, confidential disclosure agreements and trade secrets, as management deems appropriate. Our intellectual property portfolio consists of 79 issued United States and foreign patents of which 54 are currently in force, various pending United States patent applications, and various pending Patent Cooperation Treaty patent applications filed with the World Intellectual Property Organization that serves as the basis for national patent filings in countries of interest.

During 2012, we retained the services of an independent financial advisory firm to determine the fair  market value of certain patents and related patent applications, trade secrets and know-how that we own. This intellectual property directly or indirectly relates to current and anticipated advanced Solid State Lighting products. The valuation, dated November 30, 2012, was conducted in accordance with the Statement on Standards for Valuation Services promulgated by the American Institute of Certified Public Accounts and concluded that the estimated fair market value of the assets under review was approximately $70 million.
