On April 24, 2018, the Supreme Court handed down two opinions in cases related to inter partes review (IPR). In a 7-2 decision, the Court upheld the constitutionality of IPRs in Oil States Energy Services, LLC v. Greene's Energy Group, LLC. Then, in SAS Institute v. Matal, the Court ruled 5-4 that the Patent Trial and Appeal Board must review all challenged IPR claims or none at all. In this podcast, Finnegan attorneys Trenton Ward and Rachel Emsley share their insight into these two very important cases.
