SAN JOSE, CA - Monolithic Power Systems (MPS), a leading fabless manufacturer of high-performance analog and mixed-signal semiconductors, announced in a press release two rulings by the United States Court of Appeals for the Federal Circuit, which resulted in a complete victory for MPS and its customers in ongoing patent litigations with O2 Micro International Ltd. (O2).
In the first ruling, the Court affirmed the judgment from the United States District Court of Northern California that all of the claims of US Patent No. 6,396,722 (the '722 Patent) asserted against MPS and its customers were invalid on the grounds of obviousness.
In the second ruling, the Court dismissed O2’s action and overturned a judgment in the Eastern District Court of Texas against Taiwan Sumida Electronics Inc., an MPS customer, on the basis that O2 cannot assert the same invalid claims.
In December 2008, O2 instituted another action alleging patent infringement of several claims from Patent No. 7,417,382 (the '382 patent) against MPS and several customers before the United States International Trade Commission.
The 382 patent belongs to the same family as the ‘722 patent that the Court found invalid. Proceedings regarding the ‘382 patent are also pending in the Northern District Court of California.
MPS, Monolithic Power Systems, and the MPS logo are among the trademarks of Monolithic Power Systems Inc. in the US and certain other countries.
