United States Federal Circuit


Leader Technologies, Inc. v. Facebook, Inc., 2011-1366

In a patent infringement case relating to software that allows users on a network to communicate and collaborate on a large scale, the district court's judgment in favor of the defendant is affirmed, where the plaintiff's patent was invalid for being in public use or sale more than one year prior to the date the patent application was filed, since legally sufficient evidence supported the jury's verdict that the version of the plaintiff's product demonstrated and offered for sale prior to the critical date was an embodiment of the asserted claims.
