WASHINGTON, Jan 15 (Reuters) - A U.S. trade panel ruled on Thursday that SiRF Technology Holdings SIRF.O infringed on three of chipmaker Broadcom’s BRCM.O patents for global positioning systems and barred SiRF imports of the products.
The U.S. International Trade Commission said it upheld an earlier ruling by an ITC administrative law judge that SiRF’s chips infringe patents held by Broadcom subsidiary Global Locate.
The ITC also issued an exclusion order barring imports of SiRF’s infringing GPS chips and products containing the chips.
Broadcom said that the ruling brought to six the number of patents that SiRF has been found to infringe. The group of patents are related to GPS processing and sensitivity.
“We are optimistic that the ITC orders will become effective after a 60-day statutory review period so that U.S. Customs may begin enforcement and prevent any further patent infringement,” David Rosmann, Broadcom’s vice president for intellectual property litigation, said in a statement.
Broadcom shares closed up 3.5 percent at $16.72 on the Nasdaq market while SiRF ended down 20.7 percent at $1.19.
