The U.S. International Trade Commission (ITC) has affirmed an Initial Determination that SiRF Technology Holdings Inc. infringes three GPS-related patents held by Global Locate Inc., a wholly-owned subsidiary of Broadcom Corp.

The ITC also said that it would review the findings regarding three additional patents that SiRF was found to infringe.

"We are pleased that the ITC affirmed the Initial Determination that SiRF infringed three of our patents, and also confirmed the validity of all six patents. We are confident that the full Commission will ultimately affirm the findings of SiRF's infringement on the three remaining patents at issue. We also look forward to moving expeditiously to the remedy phase against SiRF," said David Rosmann, Broadcom VP, intellectual property litigation.

The ITC's notice of review comes after a two week trial earlier this year and a subsequent determination by ITC administrative law judge Carl C. Charneski that SiRF infringes six GPS-related patents held by Global Locate. The six patents that SiRF was found to infringe are U.S. patents 6,417,801; 6,937,187; 6,606,346; 7,158,080; 6,704,651; and 6,651,000relating 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. The findings subject to review involve the '346, '651 and '000 patents.

The ITC will next decide whether to implement the judge's proposed remedies against SiRF, which include a permanent exclusion order barring the importation into the United States of infringing SiRF chips and all downstream products that incorporate those chips, including personal navigation devices, GPS modules and receivers, personal digital assistants and cellphones. The ITC will also decide whether to follow the trial court's proposal to issue a cease and desist order barring SiRF from further use or sale of infringing products in the United States. Judge Charneski recommended these remedies in his Initial Determination.

The Commission has set a target date of December 8 to issue its Final Determination and remedy order.

In addition to this ITC investigation, Broadcom's claims of infringement against SiRF's multimedia processors and GPS receivers in the U.S. District Court in Santa Ana, California, will move forward after SiRF's motion to stay the case was denied last month.
