Navigating the USPTO’s Regulatory Wave: Key Comment Deadlines for Summer 2024

by Dennis Crouch

Over the past two months, the USPTO has issued an unusually large number of public comment requests related to various proposed rules and procedure changes. This wave of RFCs includes significant proposals aimed at adjusting patent fees for fiscal year 2025, refining terminal disclaimer practices, and addressing the impact of artificial intelligence on prior art and patentability. The agency is also seeking feedback on formalizing the Director Review process following Arthrex and various changes to IPR proceedings, including discretionary review. And there’s more… (more…)

Terminal Disclaimers: A Growing Concern in Patent Practice


by Dennis Crouch

In a recent post, I discussed major proposed changes to terminal disclaimer practice that could significantly impact the landscape of patent law. Today, I want to briefly note a trend that underscores why these proposed changes are more pertinent than ever: the increasing percentage of U.S. utility patents bound by a terminal disclaimer.

Major Proposed Changes to Terminal Disclaimer Practice (and You are Not Going to Like it)

by Dennis Crouch

The USPTO recently issued a notice of proposed rulemaking that could significantly impact patent practice, particularly in the realm of terminal disclaimers filed to overcome non-statutory double patenting rejections.  Under the proposed rule, a terminal disclaimer must include an agreement that the patent will be unenforceable if it is tied directly or indirectly to another patent that has any claim invalidated or canceled based on prior art (anticipation or obviousness under 35 U.S.C. 102 or 103). The new enforceability requirement would be in addition to the existing provisions that require a terminal disclaimer to match the expiration date of the disclaimed patent to the referenced patent and promise enforcement only during common ownership.

This is a major proposal that fundamentally alters the effect of terminal disclaimers.  (more…)

Patent Term Adjustment and Obviousness-Type Double Patenting: Cellect’s Bid for Supreme Court Review

by Dennis Crouch

The Federal Circuit’s August 2023 decision in In re Cellect, LLC has set-up a significant question regarding the interplay between the patent term adjustment (PTA) statute, 35 U.S.C. § 154(b), and the judicially-created doctrine of obviousness-type double patenting (OTDP). Now, Cellect is seeking Supreme Court review, recently filing a petition for an extension of time that also indicated its intent to file. Cellect’s petition is now due May 20, 2024, and I expect significant support from the patent owner community.

Patentees often receive PTA due to USPTO delays that otherwise eat into the 20-year patent term.  A fundamental issue in Cellect boils down to whether a patentee must forfeit their PTA term extensions to avoid an OTDP invalidity finding.  This comes up in situations where a patentee has two patents that cover only slightly different inventions.  Most often this is seen in family-member continuation applications, but it can also arise when applicants file several applications all within a short period.

Under the judge-made law of OTDP (more…)

USPTO Fees: Targeted Higher Fees to Push for Compact

by Dennis Crouch

The United States Patent and Trademark Office (USPTO) recently proposed a new fee structure for fiscal year 2025, which includes significant increases in various patent fees. [Read the Notice of Proposed Rulemaking] While incremental fee adjustments are common, the proposed changes for FY2025 are particularly noteworthy due to their magnitude in certain targeted areas and potential impact on applicant behavior. Many filers will likely change their practices based on the new higher fees. The USPTO appears to be using these fee adjustments as a tool to shape patent prosecution strategies, encouraging more compact patent applications and smaller patent families.  However, the USPTO is also seeking ways to ensure that the agency remains financially solvent and able to perform its statutory duties in the face of inflation and the Unleashing American Innovators Act of 2022 which reduced patent fees for small and micro entity applicants. The USPTO’s proposed fee increases are largely unchanged from the plan announced last year.

One of the most striking changes in the proposed fee structure . . . (more…)

Comments on USPTO Proposed Fee Changes

The USPTO has proposed a major set of patent fee revisions. One purpose of the new fees is to raise revenue. It is also clear that the proposal is designed to shift patent applicant behavior along certain fronts.  You can read more at the following links. Note, that the PPAC will be holding a public hearing Thursday, May 18, 2023, from 1-3 p.m. ET.

I submitted a brief comment arguing that before any fee shifting occurs, it is essential to conduct an economic analysis to forecast the impact on USPTO revenue and on innovator behavior.  In the commentary, I outline four general categories of fees, including (1) fees designed to raise money for the USPTO, (2) fees that create a costly screen, (3) fees that shift behavior without substantially shifting rights or raising overall costs, and (4) fees that discourage certain behaviors that result in a loss of rights for users. Each of these categories has potential major impacts, but categories 2 and 4 raise special concerns.

In the commentary, I identify eight specific proposed fee changes that require special attention by the USPTO chief economist or other economic experts. These include new and increased fees for AIA Trial filings, new large costs for terminal disclaimers, and substantial increases in fees for additional claims, among others.
