O2Micro Wins Patent Infringement Trial Against MPS Based Products Manufactured By Taiwan Sumida
November 17, 2005. O2Micro® International Limited (Nasdaq: OIIM) announced today that the jury in the U.S. District
Court of the Eastern District of Texas returned a verdict favorable to O2Micro in its patent infringement action against Taiwan Sumida Electronics Inc. (“Taiwan Sumida”).
The jury found that Taiwan Sumida inverter modules incorporating inverter controllers manufactured by Monolithic Power Systems, Inc. (“MPS”) infringed claims 1, 2, 9, 12 and 18 of U.S. Patent Number 6,396,722 held by O2Micro and that the infringement was willful.
The jury also found that claims 1, 2, 9, 12 and 18 of U.S. Patent Number 6,396,722 were valid. A judgment has not been entered and O2Micro expects that Taiwan Sumida may file post-trial motions with the Court seeking to overturn the jury's decision. After judgment
has been entered, Taiwan Sumida may appeal the case to the U.S. Court of Appeals for the Federal Circuit.
O2Micro was represented by Howrey LLP, Law Offices of Jones & Jones, Inc., Brown McCarroll, L.L.P. and Ireland, Carroll & Kelley, P.C. O2Micro's lead trial counsel was Henry Bunsow. Duane Mathiowetz, Franklin Jones and Calvin
Capshaw were at counsel table and were assisted at trial by counsel Otis Carroll, Frank Cote, Vinay Joshi and Rick Chang. Candace Yun, Jan Lockhart, Nick Mancuso, Maria Li, Jairo Salinas and Brian Sparks also assisted.
