Privately held Global Locate, Inc., (www.globallocate.com) a leading producer of Assisted-GPS semiconductors and software, announced that it is filing today an Answer and Counterclaims against SiRF Technology, Inc (Nasdaq:SIRF) in the U.S. District Court for the Central District of California seeking monetary damages and an injunction against SiRF's infringement of four of Global Locate's Assisted-GPS technology patents. Global Locate is filing its Answer and Counterclaims in response to a claim that SiRF initiated 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. Global Locate believes that SiRF's complaint lacks merit and will fail.

As described in its Counterclaims, 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.
