Federal Circuit Issues Decision Addressing Patent Damages Computation

January 5, 2011
On January 4, 2010, the Court of Appeals for the Federal Circuit (CAFC) issued a decision in Uniloc USA Inc. v. Microsoft Corporation. The decision rejected the 25 Percent Rule” also known as the “Goldreyer Rule” for calculating patent damages. The Court states: “This court now holds as a matter of Federal Circuit law that the 25 percent rule of thumb is a fundamentally flawed tool for determining a baseline royalty rate in a hypothetical negotiation. Evidence relying on the 25 percent rule of thumb is thus inadmissible under Daubert and the Federal Rules of Evidence, because it fails to tie a reasonable royalty base to the facts of the case at issue.”
