A year after the Obama administration’s highly unusual intervention in the case, an appeals court has killed off the last of Samsung Electronics Co.’s patent claims against Apple Inc. at the U.S. International Trade Commission.

In a one-sentence order issued Wednesday, the U.S. Court of Appeals for the Federal Circuit affirmed the ITC’s determination that Apple doesn’t infringe a Samsung patent that’s essential to wireless industry standards. The decision, which extends a winning streak for Wilmer Cutler Pickering Hale and Dorr at the Federal Circuit, comes just a week after an oral argument that pitted Wilmer’s William Lee against his perennial adversary in the Apple-Samsung fight, Charles Verhoeven of Quinn Emanuel Urquhart & Sullivan.
