David Enzminger Discusses Patent Victory for Belkin, Inc.

Winston & Strawn partner David Enzminger was quoted in the December 17, 2012 Recorder article, "Fujitsu Comes Up Empty in Koh's Courtroom."

On December 17, a jury found Fujitsu's infringement claims against Belkin, Inc., D-Link Corp., and NetGear Inc. under a patent for a "card type input/output interface device" to be invalid on the grounds that the technology existed prior to Fujitsu's first patent application in 1991.

"We felt the patent was invalid and Fujitsu actually hadn't invented what they claimed to have invented," said Mr. Enzminger, who served as lead attorney for Belkin. "Our defense was an invalidity defense."

The trial lasted only ten days; however, Mr. Enzminger said the jury fully considered the complicated issues in the case. "They were very hardworking," he said. "They dug down surprisingly deeply. They spent a lot of time going through documentary evidence."
