It’s a Matter of Timing: The PTO’s Latest Decisions on Discretionary Denials

by Sarah Mezini | May 29, 2025 | Patents

Since the US Patent & Trademark Office’s (PTO) decision to rescind former Director Vidal’s memo on procedures for post-grant proceedings where there is parallel district court litigation, Current Acting Director Coke Morgan has issued four decisions regarding requests for discretionary denials:

Twitch Interactive, Inc. v. Razdog Holdings LLC, IPR2025-00307; 00308, Paper 18 (P.T.A.B. May 16, 2025)
Amazon.com v. NL Giken, Inc., IPR2025-00250; 00407, Paper 14 (P.T.A.B. May 16, 2025)
Arm Ltd. and Mediatek, Inc. v. Daedalus Prime LLC, IPR2025-00207, Paper 10 (P.T.A.B. May 16, 2025)
Ericsson and Verizon Wireless v. Procomm International, IPR2024-01455, Paper 15 (P.T.A.B. May 16, 2025).

The Director ultimately granted two of the requests and denied the other two.

In Twitch Interactive v. Razdog Holdings LLC, the PTO denied the patent owner’s request for discretionary denial. The parallel district court proceeding did not have a scheduled trial date, and the projected trial date was far beyond the PTO’s final written decision date. The petitioner also provided statistical evidence that the district court would likely issue a stay for the pending inter partes review (IPR) proceeding. Therefore, based on a holistic assessment of the evidence presented, the PTO denied the request for discretionary denial.

In Amazon.com v. NL Giken, Inc, the PTO similarly denied the patent owner’s request for discretionary denial. Here, the issue date for the PTO’s final written decision fell before the parallel district court trial date. The abundance of time between the dates ultimately led to the PTO’s denial.

In contrast, in Arm Ltd. and Mediatek, Inc. v. Daedalus Prime LLC, the PTO granted the patent owner’s request for discretionary denial. The PTO highlighted that it was unlikely that its final written decision would be issued before the start of the district court trial. There also was a lack of probative evidence that the district court would issue a stay if an IPR proceeding was instituted.

Finally, in Ericsson and Verizon Wireless v. Procomm International, the PTO granted the patent owner’s request for discretionary denial. The PTO found that the district court trial would conclude before a final written decision was issued in the IPR proceedings, because the trial date preceded the final written decision date by nine months. Moreover, there was no evidence to support any contention that the district court would issue a stay.

Practice Note: These four decisions emphasize the importance of timing between post-grant proceedings and parallel district court litigation. The PTO is more likely to grant discretionary denial if the final written decision of the post-grant proceeding is issued after the trial concludes in the parallel district court action. If a final written decision is likely to be issued before the trial begins in the parallel proceeding, the PTO is more likely to deny a request for a discretionary denial.

Fintiv Guidelines for Post-Grant Proceedings Involving Parallel District Court Litigation

by Sarah Mezini | Apr 3, 2025 | Patents

On March 24, 2025, the US Patent & Trademark Office (PTO) released new guidance that clarifies application of the Fintiv factors when reviewing validity challenges simultaneously asserted at the Patent Trial & Appeal Board and in district court or at the US International Trade Commission.

This guidance follows the PTO’s February 28, 2025, announcement reverting to its previous guidelines for discretionary denials of petitions for post-grant proceedings where district court litigation is ongoing. That announcement rescinded the PTO’s June 21, 2022, memorandum entitled “Interim Procedure for Discretionary Denials in AIA Post-Grant Proceedings with Parallel District Court Litigation,” which prevented the Board from rejecting validity challenges where there was “compelling evidence of unpatentability.”

Based on the new guidance, the Board is more likely to defer to the district court or the Commission if the Commission’s projected final determination date is earlier than the deadline for the Board’s final written decision. The PTO pointed out that a patent challenger’s stipulation not to raise the same invalidity arguments in other proceedings if the PTO institutes an inter partes review or post grant review is highly relevant but not dispositive.

This change in policy increases the likelihood that the Board will grant discretionary denials in situations involving parallel district court or Commission proceedings.

PTO Reverts to Prior Post-Grant Guidelines for Cases Involving Parallel District Court Litigation

by Sarah Mezini | Mar 13, 2025 | Patents

On February 28, 2025, the acting director of the US Patent & Trademark Office (PTO) announced that the agency will revert to previous guidelines for discretionary denials of petitions for post-grant proceedings where there is ongoing district court litigation.

This announcement rescinds the PTO’s June 21, 2022, memorandum entitled “Interim Procedure for Discretionary Denials in AIA Post-Grant Proceedings with Parallel District Court Litigation.” The memorandum stated that the Patent Trial & Appeal Board “will not deny institution of an IPR or PGR under Fintiv (i) when a petition presents compelling evidence of unpatentability; (ii) when a request for denial under Fintiv is based on a parallel ITC proceeding; or (iii) where a petitioner stipulates not to pursue in a parallel district court proceeding the same grounds as in the petition or any grounds that could have reasonably been raised in the petition.” The memorandum effectively limited the discretion granted in Fintiv, which outlined six factors for the Board to consider when making decisions on post-grant proceedings involving parallel district court litigation.

Now that the 2022 memorandum has been rescinded, parties to post-grant proceedings should refer to Board precedent, including Fintiv and Sotera Wireless v. Masimo, for guidance when there are parallel district court proceedings. In accordance with prior guidelines, the PTO’s objective is to achieve greater consistency in its decision-making processes, especially in situations where patent validity is contested both in the courts and before the Board. The PTO emphasized that any portions of future Board decisions that rely on the 2022 memorandum will not be binding or persuasive.

Practice Note: Because of this action, the Board will now enjoy greater discretion when ruling on post-grant petitions, which may result in an increase of discretionary denials.
