Microtune Jumps 42% After Winning Patent Suit

Shares of Microtune ( TUNE) jumped 42% after a jury ruled in favor of the company in its patent-infringement case against Broadcom ( BRCM).

Shares of Microtune were up 75 cents at $2.51 in morning trading, while shares of Broadcom were down 14 cents at $15.85.

A jury in an East Texas District Court found that Broadcom willfully infringed on a Microtune patent that protects the company's MicroTuner single-chip tuner.

Texas-based Microtune said in a press release that it "anticipates the court will schedule a hearing within 30 days to consider the issues of granting an injunction with respect to the infringing tuners and to determine the amount of damages to enter on the basis of the jury's determination of infringement" of the patent.

The case is just one of a string of disputes that the two companies have filed against each other. California-based Broadcom filed a complaint alleging that Microtune engaged in unfair trade practices by importing tuners, power amplifiers and wireless-technology products that infringe on Broadcom patents, while Microtune alleged that Broadcom engaged in anticompetitive practices in the bundling of some chips.

Microtune designs, manufactures and markets radio frequency-based solutions for the global broadband communications, automotive electronics and wireless connectivity markets.
