A few months ago, in BTG International Ltd. v. Amneal Pharmaceuticals LLC, the Federal Circuit invited the Patent Office’s views on the scope of the petitioner estoppel under 35 U.S.C. § 315(e)(2). We noted then that this is an estoppel a district court may apply, but the Patent Office may not. In response to the court’s invitation, the Patent Office said that a court may apply this statutory estoppel not only to petitioners who lose an IPR, but also to those who prevail. The Office conceded that estopping prevailing IPR petitioners “leads to the counterintuitive result that a district court would not be able to consider invalidity arguments that the Board found persuasive.” But the Office said that this will have no practical effect in most cases.

The nature of any inter partes dispute apparently is to engage in even a seemingly mundane dispute. After all, that’s the dispute that may lead you to success, right? Perhaps then there is nothing surprising in an April 3, 2019, Patent Trial and Appeal Board order concerned about whether a book qualifies as prior art. That order, issued by the Board’s new “Precedential Opinion Panel,” grants an aggrieved petitioner’s request for rehearing of an earlier Board decision refusing to institute inter partes review because the petitioner apparently did not establish a book bearing a 1990 (or 1991) copyright date was publicly available before the 1995 date on which the application for the subject patent was filed. Hulu, LLC v. Sound View Innovations, LLC, Case IPR2018-01039 (Apr. 1, 2019) (order).

Incorporation by reference is not sufficient to satisfy specific reference to each prior-filed patent application to be entitled to an earlier priority date (Droplets, Inc. v. E*Trade Bank (887 F.3d 1309 (2018)). This appeal to the Federal Circuit stems from a dispute between Droplets, Inc. and E*TRADE Bank, over a patent (U.S. Patent No. 8,402,115 (“the ’115 Patent”)) owned by Droplets. At issue is the effective filing date of Droplets’ ‘115 patent.

It is puzzling, if not troubling, that the Federal Circuit recently invited (link) the Patent Office to submit a brief expressing its views on the scope of the petitioner estoppel under 35 U.S.C. § 315(e)(2), a veritable Pandora’s Box. It is puzzling because only the judiciary can apply this estoppel provision, the Patent Office cannot. It is troubling not necessarily because the Patent Office unsurprisingly accepted the court’s invitation, but because it then answered in the affirmative a broad question the court did not pose: “whether section 315(e)(2) bars a successful inter partes review petitioner from making the same arguments in district court that it prevailed on in the inter partes review.” By inviting the court to conclude as much, the Patent Office has identified a statutory gaffe that may require parties to reevaluate the risks and rewards in pursuing inter partes review in parallel with district court actions.

In Dell, Inc. v. Acceleron, LLC, 884 F.3d 1364 (Fed. Cir. 2018), the Federal Circuit determined that the Patent Trial and Appeal Board was not required to consider arguments first presented by the petitioner at oral argument, despite having remanded an earlier appeal of the Board’s decision for that very purpose. In that earlier appeal, the court had concluded that the Board deprived patent owner, Acceleron, a fair opportunity to rebut new arguments petitioner Dell presented during oral argument—arguments that convinced the Board to cancel Acceleron’s patent claims. The court had vacated the Board’s decision and remanded for reconsideration. On remand, the Board elected not to consider Dell’s new argument and, reversing itself, the Board found as a consequence that Dell had failed to establish that the challenged claims were anticipated.

Inter partes review not only provides a faster and cheaper way to challenge patent validity, but also expands the Patent Office’s ability to develop law on esoteric issues relating to prior art. The Federal Circuit’s decision Nobel Biocare Services AG v. Instradent USA, Inc. is another in a line of cases arising out of IPR proceedings dealing with the availability of conference and trade show materials as prior art. See, for example, PTABWatch posts here and here. Interestingly, the court affirmed the PTAB’s decision finding certain claims of the challenged patent anticipated by a trade show publication, whereas the court came to the opposite conclusion in a related ITC appeal based on the same publication.

In Oil States Energy Services., LLC v. Greene’s Energy Group, LLC, Justice Thomas, writing for a 7-2 majority of the Supreme Court, explained that inter partes review proceedings do not violate Article III or the Seventh Amendment of the Constitution. 138 S. Ct. 1365 (2018). But his opinion for the majority invited confusion and delay, upon the brink of which the Federal Circuit now stands. This stems from Oil States’ failure to explicitly challenge in the broad question its certiorari petition presented the retroactive application of inter partes review to its patent—a patent that issued before the procedure existed.

On October 29, 2018, the Patent and Trademark Office published a request for comments on a proposal to establish a new procedure by which patent owners may seek to amend their claims during inter partes review. Comments are due on or before December 14, 2018. The PTO proposes a pilot program implementing the new amendment process to begin shortly after the deadline for comments.
