On Friday the Solicitor General filed amicus briefs requested by the Supreme Court in two patent cases, Hikma Pharmaceuticals USA Inc. v. Vanda Pharmaceuticals Inc. and HP Inc. v. Berkheimer. In both cases, the Solicitor General recommended that the Court deny review. A closer examination of the briefs, however, shows the Solicitor General supporting a reexamination of substantive, if not not procedural, patent eligibility law, at least as expressed by the Supreme Court since Bilski v. Kappos in 2010, and in particular in the currently-pending case Athena Diagnostics, Inc. v. Mayo Collaborative Services, LLC.
