Late last week, more than half a dozen amicus briefs were filed in support of GM Global Technology Operations in a case that is set to potentially shake up design patent law. The latest briefs generally urged the en banc U.S. Court of Appeals for the Federal Circuit (CAFC) to keep the law as is in order to avoid major disruptions. In June of this year, the CAFC granted a rare en banc review of its January, 2023, decision in LKQ Corporation v. GM Global Technology Operations, which affirmed a Patent Trial and Appeal Board (PTAB) ruling that LKQ failed to show by a preponderance of the evidence that GM’s design patent was anticipated or would have been obvious.
