TEL AVIV (Dow Jones) -- A federal judge ordered Qualcomm Inc. to stop producing and marketing cellular-phone chipsets and software that infringe three Broadcom Corp. patents, Broadcom said.

U.S. District Judge James V. Selna in Santa Ana, Calif., issued an injunction against Qualcomm, Broadcom said. Broadcom brought the case in May 2005. Two years later, a jury found that Qualcomm had infringed three Broadcom patents and awarded $19.6 million of damages.

Broadcom, (BRCM)the Irvine, Calif., producer of semiconductors for wired and wireless communications, and Qualcomm, (QCOM)the San Diego producer of digital-communication technologies, have been fighting each other in court over their products.

The order prohibits Qualcomm from using Broadcom's technology that enables a cellular phone to work simultaneously over two or more networks, and Broadcom's technology designed for push-to-talk functionality, which enables a cellphone to work like a walkie-talkie.

The order enables Qualcomm to use certain Broadcom video-processing chips if it pays royalties for them, Broadcom said.
