O2Micro International Ltd announced that the United States Court of Appeals for the Federal Circuit issued a decision affirming a prior grant of summary judgment of non-infringement of U.S. Patent No. 6,259,615 by Monolithic Power Systems Inc. (MPS).

The decision does not affect the validity of the patent number which was found to be valid in a prior jury trial in May. Furthermore, the decision will have no bearing on the validity of a related patent, U.S. patent number 6,396,722 which was found to be valid in two prior jury trials in November last year and last May.

The decision is only limited to the infringement of U.S. patent number 6,259,615 by MPS inverter controllers and does not hold that MPS inverter controllers do not infringe U.S. patent number 6,396,722, said O2Micro.

The November 2005 jury verdict, entry of judgment, damage award and permanent injunction against Taiwan Sumida Electronics Inc. for infringement of U.S. patent number 6,396,722 by inverter modules incorporating inverter controllers manufactured by MPS remains in effect. Meanwhile, the prior May 2006 jury verdict also holds.
