PTO Requests Comments on Revisions to AIA Trial Proceedings


On April 21, 2023, the US Patent & Trademark Office (PTO) announced that it is seeking public input on proposed modifications to the rules of practice for inter partes reviews (IPRs) and post grant reviews (PGRs) before the Patent Trial & Appeal Board to better align the practices with the PTO’s mission to promote and protect innovation and investment in the same and to provide a less expensive alternative to district court litigation to resolve certain patentability issues while also protecting against patentee harassment.

The PTO is considering promulgating rules that the Director—and, by delegation, the Board—will use to do the following:

To create clear, predictable rules where possible, as opposed to balancing tests that decrease certainty, the PTO is considering changes that would provide for discretionary denials of petitions in the following categories, subject to certain conditions and circumstances as discussed further in the Official Notice:

The PTO also seeks comments on proposed threshold definitions that apply to one or more of these categories of petitions subject to discretionary denials. Those definitions set forth the criteria used to determine the following:

For example, one proposal with respect to the “substantial relationship” is a requirement that a patent owner and petitioner disclose anyone with an ownership interest in the patent owner or petitioner, any government funding related to the patent, any third-party litigation funding support, and any stake any party has in the outcome of the America Invents Act (AIA) proceeding or any parallel proceedings on the challenged claims.

Additional changes being considered by the PTO include the following:

The PTO will hold an information session with Under Secretary of Commerce for Intellectual Property and PTO Director Kathi Vidal to discuss the proposed rule changes on May 9, 2023, from noon to 1:00 pm EDT.

For more details about the proposed rule modifications regarding which the PTO seeks comments, see the notice here. Comments on the proposed rule changes must be received by June 20, 2023, to ensure consideration. Comments must be submitted through the Federal eRulemaking Portal. To submit comments via the portal, enter docket number PTO-P-2020-0022 on the homepage and click “search.”
