SAS Institute Inc. v. Iancu

Justia Summary

SAS sought inter partes review (35 U.S.C. 311(a)) of ComplementSoft’s software patent, alleging that all 16 of the patent’s claims were unpatentable. The Patent Office instituted review on some of the claims and denied review on the rest. The Federal Circuit rejected SAS’s argument that section 318(a) required the Board to decide the patentability of every claim challenged in the petition. The Supreme Court reversed. When the Patent Office institutes an inter partes review, it must decide the patentability of all of the claims the petitioner has challenged. Section 318(a), which states that the Board “shall issue a final written decision with respect to the patentability of any patent claim challenged by the petitioner” is mandatory and comprehensive. The Director’s claimed “partial institution” power (37 CFR 42.108(a)) appears nowhere in the statutory text. The statute envisions an inter partes review guided by the initial petition. While section 314(a) invests the Director with discretion on whether to institute review, it does not invest him with discretion regarding what claims that review will encompass. The Director’s policy argument—that partial institution is efficient because it permits the Board to focus on the most promising challenges and avoid spending time and resources on others—is properly addressed to Congress.
