UPDATE 1-CSR loses U.S. appeal in Broadcom patent case

* U.S. appeal court affirms patent ruling against CSR

* CSR says could face further litigation

* CSR shares fall 1.7 percent

LONDON, April 13 (BestGrowthStock) – A patent lawsuit between
chipmakers Broadcom (BRCM.O: ) and CSR (CSR.L: ) will resume after a
U.S. appeal court ruled against CSR in a case involving GPS
navigation chips, CSR said on Tuesday.

UK-based CSR — which makes wireless chips for customers
including Nokia (NOK1V.HE: ), Apple (AAPL.O: ) and BlackBerry maker
Research in Motion (RIM.TO: ) — also said it might face further
litigation from Broadcom or others.

“We will continue to take appropriate steps to deal with any
claims that may be made,” CSR said in a statement.

CSR shares fell 1.7 percent to 436 pence by 0809 GMT,
underperforming a flat wider market. Goldman Sachs also cut its
price target on the stock to 525 pence from 550 pence on
unrelated margin concerns.

The lawsuit concerns SiRF, a U.S. company that CSR bought a
year ago, and predates the acquisition.

The U.S. Court of Appeals for the Federal Circuit on Monday
affirmed a year-old ruling by the U.S. International Trade
Commission that SiRF had infringed on three Broadcom GPS
patents, and banned the import of the infringing chips.

SiRF has since redesigned the global positioning-system
(GPS) chips in question, and these have been imported for
consumption and sale in the United States.

“We believe this appeal was simply an attempt by SiRF to
restore its reputation,” analysts at Citi said in a note.

CSR said that as a result of the ruling a 2006 patent case
between SiRF and Broadcom, in which each is asserting patents
against the other’s products, would come unstayed and proceed.
