A U.S. District Court handed down an interim ruling in Broadcom's patent infringement case against Emulex Corp., defining which of Emulex's products potentially violate the chip maker's patents.
Judge James V. Selna issued his "favorable claim construction" ruling on Friday, which Broadcom announced on Wednesday. The ruling defined the scope of the alleged infringement and found that Emulex's OneConnect family of host bus adapters and fibre channel switches, used in networking equipment, possibly violate nine Broadcom patents.
Broadcom is a leading manufacturer for the chips used in everything from cable boxes to cell phones.
The Irvine, Calif., company is seeking damages and an injunction against Emulex, which is based in Costa Mesa, Calif. A trial is expected in September of 2011, said a Broadcom spokesperson.
Two months before it filed suit against Emulex, which makes data storage equipment, Broadcom attempted a hostile takeover of the company but eventually dropped its bid.
Shares of Broadcom fell 22 cents to $43.88 during afternoon trading, while Emulex rose 8 cents to $11.90.
