It is well accepted that the broadest reasonable interpretation (BRI) standard, which the PTO employs during patent examination, and not the Phillips standard applied in district court proceedings, is generally the proper standard to be used when interpreting claims in Post-Grant proceedings such as IPRs and reexamination proceedings.  However, in In Re CSB-System International, Inc., Appeal No. 2015-1832, the Federal Circuit reminded the PTAB that the BRI standard is not to be applied in all Post-Grant proceedings.  Instead, the Federal Circuit reaffirmed its precedent that “when an expired patent is subject to reexamination, the traditional Phillips construction standard attaches.” (p. 8). The court further held that the Phillips standard also applies when the patent expires during reexamination.

Granted v2We previously reported the May 9, 2016, Patent Office’s study that the PTAB rarely grants motions to amend.  There, we explained that patent owners rarely file motions to amend and, even when such motions are filed, the PTAB rarely grants such motions. Last week, in Google Inc. and Apple Inc., v. ContentGuard Holdings, Inc., Case CBM2015-00040, Paper 8 (PTAB June 21, 2016), the PTAB granted a Patent Owner’s motion to amend. This case is thus a rare example of the PTAB’s willingness to grant a motion to amend when the Patent Owner provides detailed arguments evidencing why a proposed, substitute claim is patentable over the “prior art known to the patent owner.”

On June 30, 2016, lead APJ Jacqueline Wright Bonilla provided an overview of the new PTAB rules during the Biotechnology/Chemical/Pharmaceutical Customer Partnership (BCP) Conference.  The final rule on Amendments to the Rules of Practice for Trials Before the Patent Trial and Appeal Board, which we have previously discussed [April 21, 2016 and August 20, 2015] was published on April 1, 2016, and was later revised in a correction to the final rule on April 27, 2016.  APJ Bonilla commented on the new rules relating to the standard for claim construction, preliminary responses by the patent owner, including testimonial evidence, word count, Rule 11-type certification, and motions for sanctions.

In Cuozzo Speed Technologies, Inc., v. Lee, the Supreme Court affirmed the Federal Circuit’s decision, upholding the PTAB’s use of the BRI standard for claim interpretation in IPRs, and determining that 35 U.S.C. § 314(d) bars judicial review of the PTAB’s decision to institute review on grounds not specifically raised in the IPR petition.

In IPR2015-00208, Shinn Fu petitioned for IPR of USPN 6,681,897 owned by Tire Hanger.  All five claims of the patent were drawn to methods of supporting vehicle wheels removed from a vehicle while on a service lift, wherein the supports would allow technicians to remove and replace the wheels without risking back injury by bending.  By all accounts, Shinn Fu mounted a strong attack against all claims in the ‘897 patent, and the PTAB instituted review.  Foregoing a dogged defense of the granted claims, Tire Hanger maintained a clear head and responded to the petition by filing a contingent motion to amend the claims rather than a Patent Owner Response.

Ground Hog DayThe much anticipated argument in Cuozzo Speed Technologies, LLC v. Lee occurred Monday, April 25, 2016 before the United States Supreme Court.  One can glean some insight from the Justices’ questions and remarks, but the ultimate outcome in this seminal decision remains uncertain.  The following reflects the tenor of the remarks of seven of the Justices’ who spoke during oral argument.  In keeping with his much reported practice at these arguments, Justice Thomas remained mute.  The following discussion focuses exclusively on the arguments concerning whether or not the PTAB may employ the “broadest reasonable construction” standard in IPRs.

Bat vs BatIn a recent decision appealing the PTAB’s finding of claims unpatentable in two different, but related re-examination proceedings, the Federal Circuit vacated and remanded the Board’s decisions based on reinterpretation of claim terms construed under the PTAB’s broadest reasonable interpretation (BRI) standard during the re-examination process (In re Varma, Appeal 2015-1502 and 2015-1667, Fed. Circ., March 10, 2016).  This decision is one of several recent decisions in which the Federal Circuit has taken the opportunity to reinterpret the PTAB’s broadest “reasonable” interpretation of the claims during a post grant proceeding and change the interpretation to be more “reasonable” in light of the specification and actual claim language.

In a pair of decisions from related IPR appeals, the Federal Circuit reversed and remanded portions of two final written decisions related to the same patent and parties because the PTAB’s construction of the claims was unreasonably broad. See, PPC Broadband, Inc. v. Corning Optical Comm’ns, Appeal Nos. 2015-1361, et al. (Fed. Cir., Feb. 22, 2016); PPC Broadband, Inc. v. Corning Optical Comm’ns, Appeal No. 2015-1364 (Fed. Cir., Feb. 22, 2016). The Federal Circuit highlighted the differences between the BRI standard applied by the USPTO and the PTAB and the Phillips standard applied in the courts, and in analyzing the PTAB’s application of the BRI standard, the CAFC focused extensively on the reasonableness of the PTAB’s construction, differentiating between a broadest possible interpretation, which may be overly broad, and the broadest reasonable interpretation in light of the claims and specification.

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. TriVascular successfully petitioned the Board to institute the review after the patent owner (Samuels) accused TriVascular of infringing the same patent in a California federal court. TriVascular’s short-lived success, however, was tempered by the Board’s claim construction in the institution decision that differed from the construction TriVascular sought in its petition.

Golden GooseOn January 15, 2016, the United States Supreme Court agreed to consider whether it is appropriate to give claims challenged in inter partes  review their “broadest reasonable construction.”  See Cuozzo Speed Tech., LLC v. Lee.  Given the Federal Circuit’s dismal recent track record when the Supreme Court has injected itself into disputed patent issues, practitioners are likely girding for a tectonic shift in IPR proceedings.  For those beleaguered by litigation from non-practicing entities, they may be justified in fearing that coveted IPR proceedings will become less useful as a bulwark against such cases.
