In a highly anticipated opinion, this morning the United States Supreme Court affirmed the Patent Trial and Appeal Board’s authority to reconsider and cancel already-issued patents via the inter partes review process under the America Invents Act.  The 7-2 decision in Oil States Services, LLC v. Greene’s Energy Group, LLC, from which Justice Gorsuch and Roberts dissented, held that inter partes review process does not violate Article III of the Constitution or the Seventh Amendment.
