In an appeal from a Patent Trial and Appeal Board’s (PTAB’s) final written decision, the Federal Circuit ruled that the PTAB’s decision to institute an inter partes review (IPR) proceeding only on a subset of prior art grounds raised by the petitioner but not on other grounds is still part of the PTAB’s “comprehensive” institution decision, which the Federal Circuit cannot review. Harmonic Inc. v. Avid Technology, Inc. No. 2015-1072 (Fed. Cir. March 1, 2016).
