The U.S. Court of Appeals for the Federal Circuit (CAFC) issued two decisions today in related appeals arising from inter partes review (IPR) proceedings between Apple Inc. and Smart Mobile Technologies LLC. In the case, Apple Inc. v. Smart Mobile Technologies LLC, the CAFC affirmed a Patent Trial and Appeal Board (PTAB) determination that Apple failed to prove certain claims of two Smart Mobile patents unpatentable as obvious, while vacating and remanding a separate portion of the same judgment that had found other claims obvious. In the companion appeal, the CAFC affirmed the PTAB’s decision rejecting Apple’s obviousness challenge to a third related patent. Circuit Judge Stark authored both opinions for a panel that included Circuit Judges Reyna and Hughes.
