  • SiRF Requests Reexamination of Broadcom Patent Ruling

    SiRF Technology Holdings, Inc. of San Jose, California, has completed filing with the U.S. Patent and Trademark Office official requests for reexamination of each of the four patents that Broadcom recently asserted against SiRF in the Santa Ana, California, federal district court.

    SiRF seeks review and invalidation of all four of the Broadcom patents named in the lawsuit, through its requests for ex-parte reexamination and in view of what it terms “substantial new questions of patentability raised by prior art not previously considered by the Patent Office,” according to the company.

    SiRF also intends to seek a stay of the federal district court case.

    SiRF and Broadcom have been engaged in an ongoing legal battle over patents held by their respective companies, both claiming patent infringement. In late June, SiRF Technology petitioned the International Trade Commission (ITC) to review part of a ruling that found that Broadcom didn’t infringe upon two of its patents as the company alleged.

    A ruling in Broadcom’s six claims of patent infringement against SiRF before the ITC is expected any day. The trial took place in April.

  • SiRF Appeals ITC Ruling on Broadcom Dispute

    SiRF Technology has petitioned the International Trade Commission (ITC) to review part of a ruling earlier this month that found that Broadcom didn’t infringe upon two of its patents as the company alleged.

    ITC Administrative Law Judge Paul Luckern issued his initial determination in the suit originally filed by SiRF against Global Locate on June 13 following a six-day trial in March in Washington, D.C. Broadcom acquired Global Locate in July 2007. The judge subsequently found that Broadcom didn’t infringe on SiRF’s intellectual property, and found one of the two patents in question to be invalid.

    SiRF said it has petitioned the ITC to review those aspects of the initial determination that found that the valid patent was not infringed by Broadcom.

    The intellectual property dispute goes back to 2006, when SiRF also took Global Locate to task in federal district court; it in turn counter-sued. Those suits were stayed pending the ITC ruling.

    Broadcom also has its own claims against SiRF before the ITC, having filed six claims of patent infringement; that trial took place in April of 2008. An initial determination in that case, heard before Administrative Law Judge Carl Charneski, should come on Aug. 8, 2008, according to the company. Broadcom also filed a lawsuit in May 2008 in federal district court, claiming infringement of four patents.

  • ITC Rules Against SiRF, for Broadcom

    Broadcom Corp. says the U.S. International Trade Commission (ITC) rejected claims by GPS chip maker SiRF Technology, which alleged that Global Locate infringed upon two of its patents. Furthermore, the ITC also found that SiRF’s asserted claims on one of the patents at issue were invalid, according to Broadcom.

    Broadcom acquired Global Locate in July 2007; the patent dispute stems back at least to 2006, when SiRF also took Global Locate to task in federal district court; it in turn counter-sued. Those suits were stayed pending the ITC ruling. ITC Administrative Law Judge Paul Luckern issued his initial determination Friday, June 13, following a six-day trial last March in Washington, D.C.

    Broadcom also has its own claims against SiRF before the ITC, having filed six claims of patent infringement; that trial took place in April of 2008. An initial determination in that case, heard before Administrative Law Judge Carl Charneski, should come on August 8, 2008, according to the company.

    Broadcom also filed a lawsuit in May 2008 in federal district court, claiming infringement of four patents.
