Defendant’s “Staged Delay” in Withdrawing FRAND Affirmative Defenses Amounted to “Rank Gamesmanship” and Supported an Award of Attorneys’ Fees

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).

Under the Lanham Act, a plaintiff who prevails on a trademark infringement claim may be entitled to recover the “defendant’s profits” as damages. The Supreme Court in Dewberry Group, Inc. v. Dewberry Engineers Inc. unanimously construed “defendant’s profits” in 35 USC § 1117(a) to mean that only the named defendant’s profits can be awarded, not the profits of other related corporate entities. The Court, however, left open the possibility that other language in § 1117(a) may allow for damages linked to the profits of related entities, if properly raised and supported.

In a series of rulings on a motion in limine, the District of Delaware recently distinguished between what qualifies as being incorporated by reference and what does not for the purposes of an anticipation defense. In short, a parenthetical citation was held to be insufficient, while three passages discussing a cited reference met the test.

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.

A District of Delaware judge recently granted a defendant’s motion to include a patent prosecution bar in its proposed protective order after determining that litigation counsel’s ability to practice before the Patent Office—without ever having represented the plaintiffs at the Patent Office in the past—weighed heavily in favor of the bar.

The Federal Circuit recently reversed a district court decision that found a patent that did not describe after-arising technology failed to satisfy the written description requirement. In so doing, the Federal Circuit explained that written description and enablement are evaluated based on the subject matter that is claimed, not the products that practice those claims. As a result, the patentee was not required to describe unclaimed, later-discovered features of the accused products despite the broad language in the claims that undisputedly covered the products.

The District of Delaware recently rejected a patentee’s argument that non-production of an opinion letter from counsel, combined with knowledge of the patent, warranted a finding that defendant induced infringement.

The District of Delaware recently denied a motion to dismiss a patent infringement complaint involving gene editing technology that sought relief under the Safe Harbor Provision of the Hatch-Waxman Act. Specifically, the court found the patentee’s complaint sufficiently alleged at least some uses of the claimed technology that, when taken as true, were not solely uses of a “patented invention” that were “reasonably related” to an FDA submission.
