ITC upholds patent ruling against SiRF

WASHINGTON, USA: Broadcom Corp., announced that the U.S. International Trade Commission (ITC) has denied the request of SiRF Technology Holdings, Inc. (SiRF) to review an Initial Determination that found no violation by Global Locate, Inc. of Section 337 of the Tariff Act of 1930. Global Locate is a wholly-owned subsidiary of Broadcom, acquired in July 2007.

ITC Administrative Law Judge Paul Luckern had previously ruled that two of SiRF's GPS patents were not infringed by Global Locate and that the asserted claims of one of the patents were invalid, following a six-day trial last March. SiRF had already dismissed two additional patents from the case prior to trial.

The Commission's Final Determination in favor of Broadcom, which concludes that investigation, follows a ruling last week by another ITC judge in a separate investigation that certain SiRF products infringe six patents owned by Global Locate.

"We are pleased that the Commission concluded its investigation by affirming the Judge's Initial Determination, which rejected SiRF's claims against Global Locate. Going forward, Broadcom and Global Locate will continue to pursue all available remedies against SiRF to protect our intellectual property." said David Rosmann, Broadcom's Vice President, Intellectual Property Litigation.
