A U.S. federal judge has clamped further restrictions on Qualcomm's ability
to sell and support certain wireless chipsets, saying that they infringe on
three patents held by rival Broadcom.

The
injunction, issued Monday by U.S. District Court Judge James Selna, prohibits
Qualcomm from making and selling certain third generation (3G) chipsets, used
to provide Internet access to mobile phones. Qualcomm is also barred from engaging
in a range of marketing and customer support activities related to its WCDMA
(Wideband Code Division Multiple Access) and EV-DO (EVolution-Data Only) chips,
which are used to process data on high-speed wireless networks.

The ruling is the latest in a series of actions in the long-running dispute
between the two chip vendors. In July, the U.S. International Trade Commission
(ITC) ruled that Qualcomm infringed Broadcom patents and barred Qualcomm from
importing chips to the U.S., but the Commission allowed mobile phone vendors
to ship the chips in their products.

"The ITC order did not go nearly as far in prohibiting other activities
from Qualcomm," said David Rosmann, vice president of intellectual property
litigation with Broadcom. "The U.S. District Court order has in some respects
much broader remedies. So the activities that are going to be barred by this
injunction go a long way to stopping Qualcomm's continued operations in support
of these infringing chips."

Broadcom sued Qualcomm in May 2005, claiming that Qualcomm's chips violated
three of the company's patents. In May of this year, a jury found in Broadcom's
favor and awarded the company US$19.6 million in damages. Monday's injunction
stems from that decision.

Broadcom is also suing Qualcomm on other patent infringement and antitrust
claims, Rosmann said. The antitrust case is expected to go to trial in 2009.

Qualcomm executives could not be reached immediately for comment.
