Recent patent infringement suits filed in U.S. District Courts
Tyler Division, Eastern District of Texas Lonestar Inventions LP vs. Advanced Micro Devices Inc.
Plaintiff Lonestar, a Texas limited partnership, claims to own the rights to U.S. Patent No. 5,208,725 issued May 4, 1993, for a High Capacitance Structure in a Semiconductor Device. The '725 Patent was assigned to Lonestar Inventions by inventor Osman E. Akcasu.
Lonestar alleges defendant AMD has been for some time and is currently infringing the '725 Patent by making, selling or using semiconductor devices embodying the patented invention, and inducing others to do so, and will continue to do so unless enjoined by the court.
"Although Lonestar does not know the full extent of AMD's infringement and inducement, Lonestar is aware that AMD has made, imported, offered to sell or induced others to make, import, sell or offer to sell in this country at least the following products: (1) the Nintendo Wii, containing chip-sets designed by AMD or its predecessors in interest; and (2) graphics cards containing the ATI 215-0669049 graphics processor, including without limitation, the Radeon HD 4870 graphics card," the original complaint states.
Lonestar alleges AMD has been given written notice that it is infringing the '725 Patent, but has failed and refused to cease infringing the patent, which Lonestar claims makes it eligible to receive enhanced damages.
Lonestar is seeking injunctive relief, compensatory and treble damages, interest, attorneys' fees, costs and other just and proper relief.
Chris Reynolds of Gibbs & Bruns LLP in Houston is representing the plaintiff.
