In TriVascular, Inc. v. Samuels, Appeal No. 2015-1631 (Fed. Cir. Feb. 5, 2016), a unanimous Federal Circuit panel affirmed a PTAB final written decision that concluded the petitioner (TriVascular) did not meet its burden of demonstrating the challenged claims were unpatentable during inter partes review.

The PTAB relied on Federal Rule of Evidence 611(c), and cited to McCormick on Evidence, § 6 (7th ed. 2013), which states “[a] leading question is one that suggests to the witness the answer desired by the examiner.” Is the PTAB, in reading a cold record and applying an unforgiving reading of the rule, setting a dangerous precedent on admissible testimony?
The AIA explicitly bestows the USPTO Director with the authority to institute IPRs and the PTAB with the authority to decide the ultimate question of patent validity. The Director delegated the authority to institute IPRs to the Board, but is it proper to assign the decision to the same APJs that render a final decision? A split panel at the Federal Circuit held that neither the AIA nor the Constitution precludes the same PTAB panel from rendering both institution and final decisions. Ethicon Endo-Surgery, Inc. v. Coviden LP, No. 2014-1771 (Fed. Cir. 2016).



Two recent PTAB final written decisions illustrate the difficulty in convincing the PTAB to grant a motion to exclude evidence, in particular on the grounds of relevance, more particularly for evidence submitted in support of a party’s claim construction position.
