Patent Case Results In Favorable Jury Verdict For Linear Technology

Profession:McDermott Will & Emery

WASHINGTON, D.C. (July 1, 2008) — Today, a unanimous jury in the U.S. District Court for the District of Delaware awarded total victory to McDermott client Linear Technology on its claim against Monolithic Power Systems for infringement of two energy saving voltage regulator patents that have seen wide industry acceptance.

We respectfully disagree with the judge's determination that it does not also violate our previous settlement agreement and we plan to appeal that ruling. Linear continues to have a significant commitment to funding research and...
