PTAB May Not Create a New Ground of its Own, But Can Rely on
Additional Art in Support of a Petition Ground
Recently, the Federal Circuit in Philips v. Google (here) explained that the Patent Trial &
Appeal Board (PTAB) may only institute trial on grounds presented
in a trial petition. 948 F.3d 1330 (Fed. Cir. 2020). That is, the
Board may not formulate its own grounds from the petition art. This
is because the Supreme Court has explained the AIA statutes do not
"contemplate a petition that asks the Director to initiate
whatever kind of inter partes review he might choose." SAS
Inst. Inc. v. Iancu, 138 S. Ct. 1348, 1355 (2018).
But, as explained this week in Lone Star Silicon Innovations
LLC v. Iancu (here), this prohibition against agency
formulated grounds does not prevent the Board from looking to
additional references for evidentiary support (such as general
knowledge in the art) to support an existing trial ground.
