Cognex says that Wieland-Werke AG, one of the world's largest copper strip manufacturers, has integrated Cognex's SmartView ICN web inspection system on its copper pickling line in Germany.
Judge Pro held that the claims of 14 patents asserted by the Lemelson Partnership are invalid and unenforceable, and not infringed by Cognex.
Cognex filed suit against the Lemelson Partnership in September of 1998, seeking a declaration that certain patents issued to Lemelson that purportedly cover machine vision are invalid, unenforceable, and not infringed by either Cognex or users of Cognex products.
In 2000, the Court combined Cognex's lawsuit with a similar suit against the Lemelson Partnership (filed at a later date) by Symbol Technologies and seven other manufacturers of bar code readers.
The case was tried in the U.S.
District Court in Las Vegas from November 18, 2002 to January 17, 2003.
Post-trial briefs were submitted to the Court on June 26, 2003.
In summarizing his 30-page decision, which was issued late Friday, Judge Pro wrote, "Having concluded that Lemelson's patent claims are unenforceable under the equitable doctrine of prosecution laches; that the asserted patent claims as construed by the Court are not infringed by Cognex because use of the accused products does not satisfy one or more of the limitations of each and every asserted claim; and that the claims are invalid for lack of written description and enablement even if construed in the manner urged by Lemelson, the Court finds that Judgment should be entered in favor of Plaintiffs."
