SAN FRANCISCO—A company going by the name Power Management Systems LLC filed a complaint earlier this week in U.S. federal court charging that semiconductor vendors Intel Corp., Freescale Semiconductor Inc. and Marvell Technology Group Ltd. market chips that infringe upon a U.S. patent controlled by Power Management Systems.
The complaint, filed in U.S. District Court in Delaware, alleges that products offered by the three chip firms infringe U.S. Patent No. 5,504,909, titled "Power Management Apparatus Co-located on the Same Integrated Circuit as the Functional Unit that it Manages." The patent, awarded in 1996, describes a novel power management system for ICs, according to the complaint.
The complaint lists the principal place of business for Power Management Systems as Frisco, Texas. A web search revealed no website or further information about the company.
The suit specifically alleges infringement of the patent by Intel's Atom Z6xx, Freescale's i.MX515 and Marvell's PXA940 products. The suit also states that the alleged infringement is not necessarily limited to these products.
The suit requests a jury trial and asks the court to award unspecified damages to Power Management Systems from all three defendants, as well as attorney's fees.
