Objectively Reasonable Invalidity Defense Shields Accused Infringer From Willful Infringement

The Federal Circuit recently vacated a decision by the Patent Trial and Appeal Board after concluding that the board’s analysis of licensing evidence offered as a secondary consideration of nonobviousness constituted legal error and was not supported by substantial evidence. According to the court, the board applied a more exacting and improperly heightened nexus standard than is required by law for license evidence.

In a recent decision designated as Informative, the USPTO Director determined that the Patent Trial and Appeal Board abused its discretion by instituting two inter partes review proceedings challenging the same patent, based on petitions advancing different constructions of the same claim term. The Director expressed concerns that permitting multiple petitions based on alternative claim constructions effectively circumvents word count limitations, strains board resources, and undermines procedural efficiency.

Earlier this year, the Federal Circuit’s decision in Qualcomm Inc. v. Apple Inc. (Qualcomm II) raised questions about the extent to which petitioners can rely on applicant admitted prior art (“AAPA”) in inter partes review proceedings.  The Federal Circuit’s recent decision in Shockwave Medical, Inc. v. Cardiovascular Sys., Inc. largely cabins the Qualcomm II decision to its particular facts and makes clear that AAPA can be used as evidence of background knowledge as part of an obviousness argument.

The Federal Circuit recently reversed a PTAB determination on remand that a patent was obvious over applicant admitted prior art (“AAPA”) in combination with prior art patents, holding that expressly designating AAPA as a “basis” for a ground is improper under 35 U.S.C. § 311(b). In doing so, the Court rejected the PTAB’s “blanket rule” that “AAPA used in combination with prior art patents or printed publications under § 311(b) is ipso facto not the basis or part of the basis of a ground.” Ultimately, while the case clarifies that expressly listing AAPA in an IPR ground is improper, the precise line between proper and improper uses of AAPA in other instances remains unclear.

In an appeal from an inter partes review, the Federal Circuit recently clarified that the enablement inquiry applied to prior art references in the context of an anticipation defense differs from the enablement inquiry applied when evaluating the claims of a patent.

The Northern District of Ohio denied a motion to compel the plaintiff to produce test results referenced in its initial disclosures and complaint. The court found that because the “test results are not facts but rather are opinions,” the information was protected as work product. Furthermore, because that testing would not be used as evidence in the litigation, the defendant was not prejudiced.

In a precedential opinion, the Federal Circuit definitively held that the Patent Trial and Appeal Board has jurisdiction over IPRs that concern expired patents.

In a patent infringement litigation in the U.S. District Court for the Eastern District of Texas, Judge Rodney Gilstrap denied a joint motion to stay the litigation pending resolution of inter partes review when it was uncertain that all defendants would be bound by the statutory estoppel provision of 35 U.S.C. § 315(e).
