SiRF loses Court Battle on Patent Infringement versus Global Locate

SiRF may be in hot water as an International Trade Commission judge just ruled that they infringe on patents held by Global Locate, a wholly owned subsidiary of Broadcom. The final ruling is not knwn, and the outcome and remedies, if needed, are not set, but if this goes against SiRF it could mean trouble in the end for them. The products that are apparently infringing on the Global Locate patents include the now very popular SirfStarIII and SiRFInstant GPS chipsets.

According to MarketWatch, "The six patents that SiRF was found to infringe are United States patents 6,417,801; 6,937,187; 6,606,346; 7,158,080; 6,704,651; 6,651,000 -- relating to extended ephemeris assistance (Long Term Orbits), calculating time in GPS receivers, enhancing sensitivity in assisted GPS systems, and implementing hardware structures for parallel correlation. "

More to come on this one, I am sure......
