Case Detail


Microsoft Corporation v. United States
On December 22, 2009, the U.S. Court of Appeals for the Federal Circuit largely upheld a district court decision that enjoined Microsoft Corp. from continuing to distribute Word (its flagship word processing software) and awarded the plaintiff more than $200 million for alleged patent infringement. The decision was a setback for WLF, which filed a brief urging the court to overturn the relief granted to the patent holder. WLF argued that the plaintiff failed to demonstrate the likelihood that it would suffer irreparable harm in the absence of an injunction – a prerequisite for an award of injunctive relief. WLF also argued that the huge damages award was the direct result of the district judge’s failure to exclude unsupported and outlandish expert testimony regarding damages supposedly suffered by the plaintiff. The appeals court rejected both arguments, finding that the trial court did not abuse its discretion in finding irreparable harm and in admitting the challenged testimony.
Case Status:
