Update: 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.

Responsive to public interest in whether it is too difficult for Patent Owners to amend claims during PTAB Trials, the Patent Office recently published a 
Biotechnology patent applicants dissatisfied with the examination of their patent applications can look to the PTAB for relief by filing an appeal – but they will need to be very, very patient. The procedures created by the America Invents Act (AIA) for challenging U.S. patents – inter partes review, post grant review, and covered business methods – have transformed strategies for contesting the validity of patents. In just a few years, the Patent Trial and Appeal Board (PTAB) has become one of the busiest forums for contesting patent validity, due in part because the PTAB must complete its review within 18 months of receiving a petition. Patent applicants dissatisfied with a patent examiner’s rejection of their patent application may appeal the rejections to the same PTAB that administers AIA trials. But, these applicants cannot expect the PTAB to decide their appeal with the same timeliness with which the PTAB completes AIA trials.

Now that Cuozzo Speed Techs., LLC v. Lee has been submitted to the Supreme Court, the next issue that may well make its way to the Court is the propriety of the Federal Circuit’s standard of reviewing the PTAB’s AIA trial decisions. Currently, the Federal Circuit reviews these decisions for substantial evidence. At least four Federal Circuit Judges do not, however, think that the court’s application of that review standard is consistent with the AIA and have concluded that the standard makes too little sense in the context of an appeal from the PTAB’s IPR decision. But because the court is bound by Supreme Court precedent to apply that standard of review, the Federal Circuit issued an order denying a petition Merck & Cie recently filed asking the full Federal Circuit to rehear a late-2015 decision issued by a divided three-judge panel in

There have been a few short articles floating around over the past few years that list the top (usually four or five) mistakes that petitioners have made to doom their IPR/CBM petitions. These articles sometimes refer to the need for the petitioner to pay attention to detail, but then often fail to go into detail about what those details might be.
