The Federal Circuit recently reversed a PTAB determination on remand that a patent was obvious over applicant admitted prior art (“AAPA”) in combination with prior art patents, holding that expressly designating AAPA as a “basis” for a ground is improper under 35 U.S.C. § 311(b). In doing so, the Court rejected the PTAB’s “blanket rule” that “AAPA used in combination with prior art patents or printed publications under § 311(b) is ipso facto not the basis or part of the basis of a ground.” Ultimately, while the case clarifies that expressly listing AAPA in an IPR ground is improper, the precise line between proper and improper uses of AAPA in other instances remains unclear.

In a precedential opinion, the Federal Circuit definitively held that the Patent Trial and Appeal Board has jurisdiction over IPRs that concern expired patents.

The Patent Trial and Appeal Board recently declined to institute a petition for IPR that was filed on the same day that the petitioner filed another petition challenging the same claims of the same patent. The board was not persuaded by petitioner’s arguments that a second petition was needed due to alleged claim construction issues or the number, length or scope differences of the challenged claims.

In an institution decision following the USPTO’s withdrawal of its Fintiv Memo, the board addressed discretionary denial of an IPR under Fintiv in view of a parallel ITC investigation. The board noted it would not consider the now-rescinded June 2022 memo from then-director Vidal which instructed that the PTAB would not deny institution of an IPR or PGR under Fintiv when the request is based on a parallel ITC investigation. The board conducted a Fintiv analysis in view of the ITC investigation, but ultimately determined that discretionary denial was not warranted in this particular situation.

The Federal Circuit affirmed a Patent Trial and Appeal Board (PTAB) final written decision holding that the prior art exception of AIA Section 102(b)(2)(B) does not apply to a prior sale by an inventor when the sale is conducted in private. According to the Federal Circuit, a sale must disclose the relevant aspects of the invention to the public to qualify for the prior art exception of Section 102(b)(2)(B).

On February 28, 2025, the USPTO announced that it was rescinding former Director Vidal’s 2022 memorandum on discretionary denials by the Patent Trial and Appeal Board. The 2022 memorandum effectively narrowed the application of discretionary denials in cases with parallel district court litigation by specifying instances where discretionary denial could not be issued. With the withdrawal of the memorandum, individual PTAB panels will regain flexibility in weighing discretionary denials. While the long-term effect of that increased flexibility is not yet known, the immediate effect is likely to be a shift towards the discretionary analysis applied by PTAB panels before the issuance of the memorandum.

The Patent Trial and Appeal Board granted institution of inter partes review of a patent directed to delivery of targeted television advertisements. The board rejected patent owner’s argument that a lack of particularity as to the asserted grounds justified denial under 35 U.S.C. § 312(a), holding that “simply including a significant amount of testimony and a number of supporting references is not, by itself, a reason to find that the particularity requirement is not met.”

The Patent Trial and Appeal Board rejected a patent owner’s assertion that petitioner should have named a third party, which was a defendant in a related district court patent infringement litigation and a party to a joint defense agreement (JDA) with petitioner, as a real party-in-interest (RPI). Had the board ruled otherwise and found the third party to be an RPI, the petition would have been time-barred under 35 U.S.C. § 315(b).

The PTAB denied a petitioner’s motion to compel routine discovery that sought information from a parallel ITC investigation for alleged inconsistent positions taken by patent owner in the IPR. The board found that patent owner had not taken inconsistent positions but warned patent owner that it had an ongoing duty to produce any information inconsistent with arguments made during the present IPR, even if that information related to arguments patent owner had dropped at the ITC.
