Broadcom Corp. won a tentative ruling prohibiting rival chipmaker Emulex Corp. from selling so-called controller chips for communications networks that were found to infringe two Broadcom patents.
U.S. District Judge James Selna in Santa Ana, California, issued a tentative decision before a hearing today on Broadcom’s request for a permanent injunction. The judge said he would allow Emulex to sell the infringing products for another 18 months to existing customers who have ordered them, while paying Broadcom a 3 percent royalty.
At the hearing, Selna said he would issue a final ruling on Broadcom’s request next week.
The judge had found last year that Emulex infringed two of Irvine, California-based Broadcom’s patents. Emulex, based in Costa Mesa, California, objected to a court-ordered ban of sales of infringing products and asked for a mandatory royalty instead.
Juanita Brooks, a lawyer for Emulex, said at today’s hearing that “incredible market disruptions” would occur if the judge would enter an injunction. She asked Selna to “not carve it out in such a way so the public should suffer because of a war between Broadcom and Emulex.”
Bill Lee, a lawyer for Broadcom, asked the judge to triple the royalty rate Emulex will have to pay Broadcom during the 18-month “sunset” period.
The case is Emulex v. Broadcom, 09-01310, U.S. District Court, Central District of California (Santa Ana).
