Emerson, ABB Rebuffed by Supreme Court in Patent Case

The U.S. Supreme Court let stand a $111 million award won by SynQor Inc. in a patent-infringement suit against nine makers of computer-system power converters, including units of Emerson Electric Co. and ABB Ltd.

The justices today turned away an appeal filed by the defendants, leaving intact a jury verdict and appeals court decision favoring SynQor, a manufacturer based in Boxborough, Massachusetts.

The dispute involved safety features that control how much electricity goes to large computer systems, as well as to telecommunication and data communication equipment.

Under the judgment in the case, Emerson’s Artesyn and Astec units had to pay $14 million of the award and ABB’s Power-One unit more than $25 million. The companies also were told to pay additional damages for infringement.

The case is Artesyn Technologies v. SynQor, 13-375.
