Microtune claims victory in Broadcom suit

Ending a long and arduous legal battle, a Texas jury this week ruled in favor of Microtune Inc. in a patent infringement case it had brought against silicon giant Broadcom Corp.

Microtune alleged in the case that Broadcom's BCM 3415 microchip infringed on a Microtune patent for a "highly integrated television tuner on a single microcircuit." The jury found that Broadcom infringed on that patent (No. 5,737,035) and did so willfully, Microtune said.

Microtune said it expects the court will schedule a hearing within 30 days to consider whether to grant an injunction on the infringing Broadcom product and to determine the amount of financial damages owed by Broadcom, if any.

The news pushed Microtune shares up almost 47 percent to $2.58 per share in early trading Friday. Broadcom shares, meanwhile, were down 27 cents to $15.72 apiece.

This week's jury finding probably won't end the Microtune-Broadcom battle, however. Broadcom in January filed suit against Microtune, claiming that a number of tuner, power amplifiers and Bluetooth-based products made by Microtune infringe on three Broadcom patents.
