Traditional equitable defenses do not apply to IPR proceedings

Husky Injection Molding v. Athena Automation (Fed. Cir. 2016)

Referring to the headline. The PTAB (acting on behalf of the PTO Director) held that traditional equitable defenses do not apply to IPR proceedings.  Because this holding was made as part of an IPR institution decision, the appeal was dismissed for lack of jurisdiction. 

The case here is interesting because Husky’s former owner (Schad) is the founder of competitor Athena.  Schad is also co-inventor of Husky’s U.S. Patent No. 7,670,536 – that Schad’s company challenged in an IPR proceedings.  The PTAB ultimately found some of the challenged claims valid and cancelled others.

On appeal Husky argues that assignor estoppel bars the IPR proceeding.  The PTAB rejected that contention – holding that traditional equitable defenses do not apply to IPR proceedings.  Athena v. Husky, IPR No. 2013-00290 (P.T.A.B. Oct. 25, 2013) (Institution Decision on behalf of the Director).    On appeal, the Federal Circuit dismissed — holding that the institution decision is not appealable. 35 U.S.C. 314(d) (“The determination by the Director whether to institute an inter partes review under this section shall be final and nonappealable.”); Although the Supreme Court in Cuozzo suggested that some appeals of institution decisions may be available.  Here, however, the court rejected the idea of venturing into that abyss:

[Prior cases] establish a two-part inquiry for determining whether we may review a particular challenge to the decision whether to institute. First, we must determine whether the challenge at issue is “closely tied to the application and interpretation of statutes related to the Patent Office’s decision to initiate inter partes review,” or if it instead “implicate[s] constitutional questions,” “depend[s] on other less closely related statutes,” or “present[s] other questions of interpretation that reach, in terms of scope and impact,” “well beyond ‘this section.’” Cuozzo.  If the latter, our authority to review the decision to institute appears unfettered. But if the former, § 314(d) forbids our review. One further exception remains, however. At the second step of the inquiry, we must ask if, despite the challenge being grounded in a “statute closely related to that decision to institute,” it is nevertheless directed to the Board’s ultimate invalidation authority with respect to a specific patent. Id.; see also Versata; and Achates. If so, we may review the challenge.

After rejecting Husky’s challenge of the institution decision, the Federal Circuit moved to Athena’s appeal.

Incorporation by Reference: Athena challenged the portion of the Board’s opinion finding some of the claims not anticipated.  The basic issue is that the prior art (Glaesener – U.S. Patent Pub. No. 2004-0208950) did not itself disclose all of the claimed elements.  However Glaesener referred particularly to a prior patent (Choi): noting that Choi described “pineapple and toothed-ring mechanism” and in a separate paragraph stating that “All cross-referenced patents and application[s] referred to in this specification are hereby incorporated by reference.”  The combination of Choi and Glaesener do (arguably) teach all of the claim element but the Board refused to treat them as a single document despite the incorporation by reference. On appeal, the Federal Circuit has vacated that holding.

The standard:

A host document incorporates material by reference if it “identif[ies] with detailed particularity what specific material it incorporates and clearly indicate[s] where that material is found in the various documents.” Advanced Display Sys., Inc. v. Kent State Univ., 212 F.3d 1272 (Fed. Cir. 2000). . . .  In making such a determination, we assess whether a skilled artisan would understand the host document to describe with sufficient particularity the material to be incorporated [giving no deference on appeal].  . . . [Thus t]he incorporation standard relies only on the reasonably skilled artisan and his or her ability to deduce from language, however imprecise, what a host document aims to incorporate

Here, the court found sufficient particularity to incorporate Choi by reference – noting that PHOSITA would “appreciate Glaesener’s reference of ‘pineapple and toothed-ring’ to describe, with sufficient particularity” the securing assemblies in Choi. “To find otherwise would be to undervalue the knowledge of a skilled artisan.”  On remand, the Board will need to re-evaluate anticipation based upon Glaesener now expanded by Choi.
