Earlier today the United States Supreme Court issued its decision in Oil States v. Green Energy, finding that inter partes review is constitutional both under Article III and the Seventh Amendment to the United States Constitution. In a 7-2 decision, the Court determined that patents are a government franchise that are subject to review by the Patent Office even after granting, and can be revoked at any time.
