SAN JOSE, Calif., Jan. 30, 2007 (PRIME NEWSWIRE) -- Privately held Global Locate Inc., (www.globallocate.com) a leading producer of Assisted-GPS semiconductors and software, announced that it is filing today an Amended Answer and Counterclaims against SiRF Technology, Inc (Nasdaq:SIRF) in the U.S. District Court for the Central District of California asserting that SiRF has violated federal antitrust laws and state unfair competition laws by initiating "sham" litigation against Global Locate that SiRF knew to be meritless.
As described in Global Locate's Amended Counter claims, SiRF initiated patent-infringement litigation against Global Locate on December 15, 2006, after SiRF's stock price dropped precipitously on news that TomTom, a major SiRF customer, had awarded a significant contract to Global Locate. The Amended Counterclaims allege that SiRF filed objectively meritless claims against Global Locate for infringement of multiple patents immediately after the news was announced and without engaging in a good faith investigation or analysis of potential infringement, in order to maintain a monopoly in and to attempt to monopolize relevant markets, in violation of Section 2 of the Sherman Antitrust Act and California's Unfair Competition Law.
In a previous filing on January 8, 2007, Global Locate asserted counterclaims against SiRF for infringement of four of Global Locate's patents. Global Locate's Patent No.s 6,542,820 and 6,560,534 cover proprietary, Long Term Orbit (LTO(tm)) technology invented by Global Locate. LTO extends for several days the usability period of ephemeris assistance data, thereby minimizing the start-up time and enhancing the sensitivity of mobile devices. Global Locate Patent No. 6,704,651 covers certain proprietary processing algorithms that utilize ephemeris data to improve sensitivity in a GPS receiver. Global Locate Patent No. 6,606,346 covers proprietary techniques for achieving massive parallel correlation, such as used in Global Locate GPS products, including Hammerhead(tm), the world's first single-die GPS receiver IC. Global Locate alleges that each of these patents has been, and is being, infringed by SiRF.
