FEDERAL CIRCUIT REINSTATES JUDGMENT AGAINST MICROSOFT IN ANTIPIRACY PATENT CASE

摘要

A jury's finding that the antipiracy system used in Microsoft's Windows XP operating system infringed a patent on similar technology was supported by substantial evidence, the U.S. Court of Appeals for the Federal Circuit has ruled. Uniloc USA, Inc. v. Microsoft Corp., 2011 WL 9738 (Fed. Cir. 2011). The court reinstated the jury's finding that Microsoft is liable to Uniloc USA Inc. for infringing U.S. Patent No. 5,490,216 for a "system of software registration." The court also upheld the jury's finding that the patent was valid.
