Causal-nexus for a permanent injunction only requires ‘some connection’ to infringement

The district court denied a request for a permanent injunction against Metaswitch after a jury found infringement because Genband failed to establish irreparable harm. More specifically, the court found that Genband failed to establish a causal-nexus between infringement and irreparable harm, i.e. that “the patent features drive demand for the product.” The Federal Circuit remanded because this causal-nexus requirement was too stringent. The Federal Circuit explained that the court could not have confidence as to the answer to the causation question under the standard properly governing the inquiry or whether there is any independent ground for the district court finding no irreparable harm or otherwise denying an injunction.
