Question mark warning sign

On August 12, 2016, the Federal Circuit issued an order vacating its decision in In re Aqua Products, Inc., 823 F.3d 1369 (Fed. Cir. 2016), and reinstating the appeal after granting the aggrieved patent owner’s petition for rehearing en banc.  We wrote about this decision a few months ago:

The Federal Circuit confirmed in a precedential opinion that the burden to prove patentability of an amended claim in an IPR proceeding rests squarely with the patentee, and in deciding a motion to amend claims, the Board only need consider the arguments presented by the patentee, not perform a full reexamination of the proposed claims. In In re Aqua Products, Inc., Appeal No. 2015-1177 (Fed. Cir. May 25, 2016), the Federal Circuit affirmed the PTAB’s denial of patentee Aqua’s motion to substitute claims because Aqua failed to prove patentability of the substitute claims.

In In Re Magnum Oil Tools International Ltd., the Federal Circuit reversed the PTAB’s final decision cancelling challenged claims for obviousness because the record did not include substantial evidence of a motivation to combine references, and because the PTAB improperly shifted the burden of proof on this issue to the patent owner.

Petitioner McClinton Energy Group filed an IPR petition challenging claims of a patent relating to technology for “fracking” (oil drilling using hydraulic fracturing). In fracking, a wellbore is drilled into the earth, and a fluid mixture is injected into the wellbore. Downhole plugs are used to divide the wellbore into separate sections so that different sections of the wellbore may be fracked at different times.

A handing to help their partner in mountains.

In a bit of “inside baseball,” the PTAB recently clarified the difference between supplemental evidence and supplemental information.  Practitioners would do well to give careful attention to this distinction.  The difference can have profound consequences to an IPR Petitioner.

In Generico LLC v. Dr. Falk Pharma GmbH, IPR2016-00297, Paper No. 15 (July 15, 2016), the PTAB entered an order regarding the conduct of proceedings.  The order addressed the Petitioner’s request to file a motion to supplement information pursuant to 37 C.F.R. §42.123.  The Petitioner sought to file information in response to objections the Patent Owner made to evidence submitted by Petitioner.  Specifically, the Patent Owner had objected that Petitioner’s prior art references would not have been relied upon by a person of ordinary skill in the art, and that the Petitioner’s declarant was not qualified to speak to the views of a person of ordinary skill in the art.  To address these objections, the Petitioner sought the PTAB’s authorization to file a supplemental declaration and documents from a parallel district court litigation.

In Cuozzo Speed Technologies, LLC v. Lee, the Supreme Court recognized that a “district court may find a patent claim to be valid, and the agency may later cancel that claim in its own review.”  The Court also recognized that because of the different evidentiary burdens in court versus before the agency—the Patent Office—“the possibility of inconsistent results is inherent to Congress’[s] regulatory design.” Is that inconsistency sensible? As good a case as any to consider that question involves a global pharmaceutical company, one of its top-selling drug products, and a patent it owns that covers the administration of that drug product.

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.

No ExcusesInstitution was denied in two IPR proceedings on the grounds that the petitions were filed more than one year after petitioner was served with a complaint alleging patent infringement. The documents were electronically filed but proof of payment of filing fees were one minute and nine minutes late, respectively. Additionally service had not been completed before the midnight deadline.

MapUpdate: The Supreme Court issued a decision on April 20, 2020  holding that the patent statute (35 U.S.C. § 314(d)) bars judicial review of a PTAB decision of whether an inter partes review petition is time-barred pursuant to 35 USC 315(b). As stated by the Court, the PTAB’s “application of §315(b)’s time limit, we hold, is closely related to its decision whether to institute inter partes review and is therefore rendered nonappealable by§314(d).”

Original Post: The Patent Trial and Appeal Board recently designated five opinions as “precedential.” Each of these opinions addresses procedural aspects of AIA proceedings, including requests for additional discovery, the one-year time period for filing a petition, amending claims, and requirements for PTAB consideration of a petition. A summary of each opinion follows.
Continue Reading PTAB Provides Procedural Guidance with Five Precedential Opinions

Federal district courts are inclined to stay patent litigations when requested by patent challengers on the basis that the patent-in-suit is undergoing an AIA review proceeding at the USPTO; and those not so inclined, specifically in the Eastern District of Texas, have been corrected by the Federal Circuit. But this favorable disposition toward stays occurs only up to a point. That point appears to be when the trial verdict has been rendered – even if that verdict is contrary to the PTAB’s determination.

stamp denied with red text on whiteResponsive to public interest in whether it is too difficult for Patent Owners to amend claims during PTAB Trials, the Patent Office recently published a study providing aggregate data about motions to amend filed with the PTAB since its inception in 2013.  The study, which was published by PTAB Chief Judge Nathan Kelly in the May 9, 2016 edition of the USPTO’s “Director’s Forum Blog,” confirms what the public, and certainly the patent bar, has suspected since the AIA created the PTAB to handle IPR, CBM, and PGR Trials: (1) that Patent Owners very rarely filed motions to amend, and (2) motions to amend, when filed, are rarely successful.

Know the RulesRevised rules for PTAB trials, which were published for comment in August 2015, have now been finalized and will be effective for all petitions filed on or after May 2, 2016.

As we previously reported, the new rules clarify procedures for addressing when the PTAB will apply a Phillips-type claim construction for patents that may expire before a final written decision is issued; substitute word count limits for briefs instead of page limits; incorporate a Rule 11-like certification for papers submitted to the PTAB, and revise the time period for exchange of demonstrative exhibits prior to final hearing.
