U.S. court leaves ban on Qualcomm selling some chips

LOS ANGELES (Reuters) - Broadcom Corp (BRCM.O: Quote, Profile, Research, Stock Buzz) said on Wednesday a U.S. appeals court let stand a lower court order barring wireless chip maker Qualcomm Inc (QCOM.O: Quote, Profile, Research, Stock Buzz) from selling chips that infringe on three of its patents.

The U.S. Court of Appeals for the Federal Circuit in Washington, D.C. rejected a bid by Qualcomm to lift a California trial court's injunction that stopped it from selling chips found by a California jury in 2007 to infringe on the Broadcom patents.

Qualcomm wanted to continue selling the third-generation, or 3G, WCDMA chips while it appealed that verdict.

The appeals court, in its ruling on Tuesday, also dismissed an attempt by Sprint Nextel Corp (S.N: Quote, Profile, Research, Stock Buzz) to intervene in the case.

"We are gratified that the U.S. Court of Appeals rejected Qualcomm's motion for a stay, leaving in force the injunction against Qualcomm's infringement issued by the U.S. District Court in Santa Ana," Broadcom General Counsel David Dull said in a statement.

A Qualcomm spokeswoman said although the motion for a stay was denied, the appeals court granted the company's request for an expedited schedule.

WCDMA mobile wireless technology provides much higher data speeds to mobile and portable wireless devices than most North American networks.

Under U.S. District Judge James Selna's order, Qualcomm also must pay mandatory royalties to Broadcom for the chips it sells during the "sunset period" ending January 31, 2009.

Selna ruled that after the "sunset" date, Qualcomm would be permanently barred from infringing the three Broadcom patents.
