SAN FRANCISCO—A U.S. federal court found that network chip vendor Emulex Corp. infringed on two patents held by rival chip vendor Broadcom Corp., Broadcom said Monday (Dec. 19).
Broadcom (Irvine, Calif.) said that the U.s. District Court for the Central District of California found that Emulex infringed on U.S. Patent Nos. 7,058,150 and 7,471,691, both held by Broadcom. Infringing products include Emulex's BladeEngine 2 (BE2), BladeEngine 3 (BE3) and Lancer (XE201) chips and four of Emulex's Fibre Channel switch products, according to Braodcom.
The BE2 and BE3 are 10 Gigabit Ethernet controllers, which are sold as Ethernet controllers and used in Emulex's OneConnect converged network adapters, according to Broadcom.
Broadcom said it requested that the court enter a permanent injunction prohibiting Emulex from manufacturing, using, selling or supporting the infringing products in the U.S. Broadcom has asked the court to rule on that injunction request in the first quarter of 2012, the company said.
According to Broadcom, the court also rejected Emulex's challenge to the validity of the patents and rejected Emulex's challenge to an earlier damages award for the '150 patent.
Emulex (Costa Mesa, Calif.) did not immediately respond to request for comment on the ruling.
Broadcom and Emulex have a colorful history that includes a failed 2009 bid by Broadcom to acquire Emulex.
Emulex has not been doing well these past few years, and it should be attributed to this lawsuit that forced them to withdraw some of their products. Such a case involving patents could seriously damage a company's revenue stream.
