Monolithic Power Systems Announces The Resolution In MPS's Favor Of A Patent Infringement Lawsuit Filed By Bel Power Solutions; As Part Of The Case Dismissal, Bel Power Agreed To Pay MPS's Court Costs In The Amount Of $50,000

Monolithic Power Systems, Inc. (MPS) (NASDAQ:MPWR), a fabless global company that provides high-performance, semiconductor-based power electronics solutions, announced today the resolution in MPS's favor of a patent infringement lawsuit filed by Bel Power Solutions, Inc. ("Bel Power") in the U.S. District Court for the Western District of Texas. As part of the case dismissal, Bel Power agreed to pay MPS's court costs in the amount of $50,000.

Bel Power had asserted claims of patent infringement against MPS related to six semiconductor patents owned by Bel Power. The Western District Court of Texas ruled in MPS's favor by granting MPS's motion for summary judgment of non-infringement on all patent claims. In addition, MPS had initiated ex parte reexamination proceedings at the U.S. Patent and Trademark Office that resulted in the cancellation of four of Bel Power's patents. After those events, Bel Power agreed to resolve the lawsuit in MPS's favor by acknowledging that MPS was the prevailing party, and agreeing to pay MPS's court costs pursuant to Federal Rule of Civil Procedure 54(d) in the amount of $50,000.

MPS was represented by the law firm Perkins Coie LLP in its successful defense of Bel Power's lawsuit.
