Federal court rules against Qualcomm in patent case

SAN DIEGO-A federal judge in the U.S. District Court has ruled against CDMA proprietor Qualcomm Inc. in a patent case against Maxim Integrated Products Inc.

The court held a contrary view to Qualcomm’s claim that Maxim had no right to sell receivers and transceivers to cell-phone makers because of Qualcomm’s CDMA licenses.

Qualcomm sued Maxim for patent infringement in December 2002. In April, Maxim countered with an antitrust lawsuit against Qualcomm.
