In the past, moving to amend the challenged claims during IPR was largely futile. The PTAB denied nearly all motions to amend, and many patent owners that might have benefited from amendment chose not to pursue it. But the rules concerning amendment in IPR are changing, and the number and success rate of motions to amend are ticking up. Patent owners have new reasons to think that amendment might save their patents from IPR.
Last week, the Supreme Court heard oral arguments in Oil States Energy Services v. Greene’s Energy Group—a case that addresses whether inter partes review unconstitutionally usurps the federal courts’ authority to adjudicate the validity of patents. An examination of the Justices’ questions provides hints of how they are thinking and suggests that IPRs may survive constitutional review.
Last week, the U.S. Supreme Court heard oral arguments in two patent cases concerning IPRs. The first case (Oil States Energy Services v. Greene’s Energy Group) has garnered much of the attention because it concerns the constitutionality of IPRs, but the second case (SAS Institute Inc. v. Matal) may actually have a bigger impact on how IPRs work. In SAS, the Supreme Court considered the PTAB’s practice of selecting which challenged claims it reviews, rather than, once it institutes a trial, issuing a final decision on the patentability of all claims challenged in the petition. The oral arguments suggest how the Justices are approaching the case.
