Supreme Court Update: June 2024

The US Supreme Court’s October 2023 term will come to a close later this month.  The patent side has not seen much action in terms of new cases. 27 IP-related petitions for writ of certiorari have been filed during this time. Of those 23 have been denied. Four recently filed petitions are still pending. In each of the remaining cases, respondent has indicated that it will be filing a brief.

  • Cellect, LLC v. Vidal (23-1231): Whether a patent procured in good faith can be invalidated for obviousness-type double patenting when the improper term extension is due to Patent Term Adjustment.  NYIPLA amicus in support; USPTO responsive brief due: July 22, 2024.
  • Chestek PLLC v. Vidal (23-1217): Whether the USPTO is exempt from notice-and-comment requirements when exercising its rulemaking power under 35 U.S.C. § 2(b)(2). USPTO responsive brief due: July 15, 2024.
  • Eolas Technologies Inc. v. Amazon.com, Inc. (23-1184): Patent eligibility issues. Responsive brief due: July 31, 2024.
  • Surti v. Fleet Engineers, Inc. (23-1142): Pro se patent owner focused on DoE as well as tortious interference. Responsive brief due: July 22, 2024.

I’ve listed these in what I see as the most to least likely grant.  Cellect is of particular interest as debates over double patenting continue. Based upon the timing of the briefs, a certiorari decision won’t come until the Fall.

Commenting on the USPTO’s Proposed Rule on Terminal Disclaimers

[I have substantially updated this post – correcting a couple of issues from the original and also added info from the letter from former USPTO leaders. – DC 6/1/24]

by Dennis Crouch

As I have previously discussed on Patently-O, 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. Dennis Crouch, Major Proposed Changes to Terminal Disclaimer Practice (and You are Not Going to Like it), Patently-O (May 9, 2024).  Under the proposed rule, a terminal disclaimer will only be accepted by the USPTO if it includes an agreement that the patent will be unenforceable if 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). This proposal has generated significant debate among patent practitioners, with many expressing concerns about its potential impact on innovation and patent rights.  It is a dramatic change in practice because the typical rule required by statute is that the validity of each patent claim must be separately adjudged. See 35 U.S.C. § 282(a).

The comment period is open until early July, but a number of comments have already been submitted. And I looked through them in order to get some early feedback.  You can read the comments here (more…)

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…)
