Thryv blocks appellate review of PTAB time-bar institution decisions

Thryv v. Click-to-Call became a key Supreme Court PTAB procedure decision in 2020.

The Court held that the statutory bar on appeals from institution decisions also blocked judicial review of the PTO's application of the one-year time bar under Section 315(b).

For patent owners, the ruling made institution-stage timing disputes harder to revive after a final written decision.

For petitioners, Thryv strengthened the finality of institution decisions and narrowed a procedural attack path on appeal.
