Federal Circuit Vacates Summary Judgment of Non-Enablement Where the Only Alleged Non-Enabled Systems Did Not Practice the Claims

In 2012, McRO, Inc., d/b/a Planet Blue (McRO) asserted U.S. Patent No. 6,611,278 (the “’278 Patent”) against defendant Bandai Namco Games Am. Inc. and over a dozen other video game developers (the “Developers”) in the District Court for the Central District of California. The ’278 Patent is directed to animating lip synchronization and facial expressions of animated characters three-dimensionally via a computer. The Developers produce and sell videogames with software that models facial animations in video game characters.

Previously, animators used “morph weight sets”—a set of values that, when applied, alter the animated subject’s default appearance so that they appear to speak a specific sound (e.g. “oo”)—and manually set the weight of each frame of a video game character’s mouth to properly depict them speaking. McRO patented a method to automate this process and generate character animations. Relevant to this appeal, McRO claimed a method of “obtaining a first set of rules that defines a morph weight set stream as a function of phoneme sequence and times associated with said phoneme sequence,” where a “phoneme” is a distinct unit of sound.

In a prior case, the district court determined that the asserted method claims of the ’278 Patent were invalid under 35 U.S.C. § 101 because they were directed to patent ineligible abstract subject matter. The Federal Circuit reversed that decision and remanded the case to the district court. On remand, the district court again found the claims invalid, this time granting the Developers’ motion for summary judgment of non-enablement. The district court also granted summary judgment of non-infringement. Specific to invalidity, the Developers relied on two animation techniques—bones animation and the BALDI system—as examples of systems not enabled by the specification of the ’278 Patent. The district court agreed that a person of skill in the art would be unable to practice the full scope of claim 1 because those techniques were not enabled. McRO appealed.

Enablement is a statutory requirement contained in 35 U.S.C. § 112. In short, a patentee must describe how to make and use the full scope of the invention without undue experimentation. Courts assess whether undue experimentation exists by utilizing the factors described in In re Wands. 858 F.2d 731 (Fed. Cir. 1988). Critically, however, § 112 requires enablement of only what is claimed, and is analyzed after the precise scope of the claimed invention is defined. A Wands analysis involves a concrete identification of embodiment(s) that are not enabled—particular products or processes that fall within the claim—so that breadth is shown concretely and not as an abstract possibility.

On appeal, the Developers argued that the bones animation and the BALDI system were not enabled. The Federal Circuit, however, determined that those animation techniques did not practice the claims. And because the bones animation and the BALDI system were the only examples identified by the Developers as not enabled, the court’s non-infringement determination left the Developers without a single specific example of a system that was both not enabled and practiced the claim. Without the support of a specifically covered technique, the Federal Circuit held that the district court’s non-enablement determination could no longer stand—it was too abstract and conclusory to support summary judgment of non-enablement.

Practice tip: When attempting to show that a patent does not enable the full scope of the claims, patent challengers should identify specific examples of non-enabled products or processes that practice the claims, and try to avoid relying solely on accused products or processes for which infringement may also be contested.

McRO, Inc. v. Bandai Namco Games Am., No. 19-1557 (Fed. Cir. May 20, 2020) (J. Taranto, Reyna, Mayer)

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.

A Northern District of California judge recently granted a motion to reconsider his summary judgment ruling that defendant was barred from raising certain “device art” due to IPR estoppel under 35 U.S.C. § 315(e)(2). In the original ruling, the judge adopted the broader rule that IPR estoppel applies to device art that is “materially identical” to patents or printed publications that petitioners raised, or could have raised, in an IPR. Following that ruling, however, the Federal Circuit issued its Ingenico decision adopting the narrower view that IPR estoppel applies only to “grounds” based on patents and printed publications and not to device-based grounds. Citing Ingenico as a “change of law,” defendant moved for reconsideration of the court’s ruling, and the court granted the motion.

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.

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.
