A federal judge this week issued an injunction against Qualcomm stemming from its infringement of three Broadcom Corp. patents, Broadcom announced. The injunction prohibits Qualcomm from making, using and selling chipsets and software that infringe on the patents. Specific actions that are prohibited include entering or fulfilling product orders; setting, determining or approving terms of sale; writing, modifying or updating software; developing or modifying circuits; writing, modifying or updating hardware description code language; or taping out or preparing documentation for the infringing products, Broadcom said.
