Emerson’s Artesyn Loses Bid to Overturn SynQor Patent Win

SynQor Inc.’s $95 million patent-infringement victory against nine manufacturers of power converters in computer systems, including Emerson Electric Co.’s Artesyn, was upheld today by a U.S. appeals court.

The U.S. Court of Appeals for the Federal Circuit in Washington upheld a jury verdict won by SynQor and said the trial judge was correct to enhance the damage award. The decision was posted on the court’s website.

The dispute is over safety features that control how much electricity goes to large computer systems, as well as telecommunication and data communication equipment. The other companies that remained in the appeal are Emerson’s Astec, Delta America Ltd., Bel Fuse Inc. and Murata Manufacturing Co.

Emerson’s Artesyn and Astec were told to pay about $14 million; Delta $5.8 million; Murata about $18 million; and Bel Fuse $8.1 million, according to the final judgment issued by the judge in the case. The companies also were told to pay additional damages for infringement after the verdict, and $500,000 in sanctions were imposed on Delta for violating court rules.

The case is SynQor Inc. v. Artesyn Technologies Inc., 2011-1191, U.S. Court of Appeals for the Federal Circuit (Washington). The lower court case is SynQor Inc. v. Artesyn Technologies Inc., 07cv497, U.S. District Court for the Eastern District of Texas (Marshall).
