Fenwick & West Secures $12M Trade Secret Jury Award for O2 Micro and Obtains Favorable Result on Opponent's Patent Claims

July 18, 2005

After a three-week jury trial in the U.S. District Court for the Northern District California, Fenwick & West LLP helped its client O2 Micro International (O2 Micro) secure a $12 million jury award for trade secret misappropriation against Monolithic Power Systems (MPS). The jury also found that two patents which MPS had asserted against O2 Micro were invalid and were not infringed. On the trade secret claim, the jury found that MPS misappropriated certain trade secret information belonging to 02 Micro, a developer of power management and security components for computers and handheld devices, and that MPS misappropriated the trade secrets willfully and with malice. The jury awarded O2 Micro $12 million dollars for MPS' unjust enrichment resulting from the misappropriation. On the patent claim by MPS, the jury found that O2 Micro's accused products do not infringe any asserted claims of United States Patents 6,114,814 and 6,316,881, and found that all asserted claims of both patents are invalid because they are anticipated by the prior art.

O2 Micro was represented by Fenwick & West partners Charlene Morrow and Michael Sacksteder, and associates Heather Mewes, Maclain Wells and Jae Won Song. Daniel Johnson of Morgan Lewis also represented O2 Micro in the trial.
