The Oil States case focuses on whether it’s constitutional for the Patent and Trademark Office (PTO) to review the validity of a patent after they issue it—whether the PTO can go back and double-check its own work, in other words.
Generally, the Justices (other than Justice Gorsuch, who made his position clear—but didn’t see much support for it from other Justices) seem comfortable with the PTO doing this. While a few expressed concerns about specific procedural aspects of IPR, there was little real concern about whether it was appropriate to have this kind of double-check of an agency’s own work.
Justice Gorsuch appears to feel that IPR is inappropriate, but the other Justices appear inclined to uphold it as constitutional even as they continue to signal that they want to monitor the procedure to make sure it’s being conducted fairly.
