SiRF Found to Infringe on Global Locate Patents - Order Issued to Stop Imports
SiRF is running into more trouble with the courts over the long running patent infringement battles with Broadcom, the parent of Global Locate. The court upheld a previous ruling that SiRF infringed on Global Locate patents - six in all, and is not barring the importation of products with infringing SiRF products in them. Apparently these orders go into effect 60 days after an administrative review period. That should also be enough time to get SiRF to capitulate and cut a deal with Broadcom to license the patents. GPS Makers have moved away from SiRF, a pioneer in super sensitive chipsets, in recent years as they sought cheaper, more diversified supply opportunities.
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; and 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.
