Patent infringers are supposed to pay damages, but the award in this case struck many as ridiculous. Some Samsung smartphones contained one or two purely decorative design elements that had been patented by Apple. But instead of paying modest damages for what many see as a tiny infringement, Samsung was ordered to pay $399 million – all the profits the company had made from its infringing phones. The Federal Circuit said it had no choice but to approve those damages; it was constrained by statute. Critics, however, said that the Federal Circuit had misinterpreted the statute. They fret the court’s error will unleash a wave of design patent infringement suits that will harm innovation, stifle competition, and empower patent trolls. Which is why so many will be paying close attention on 11 October, when this dispute comes before the US Supreme Court.
