Code, copies, and consequences: $185 million verdict uninstalled!

by Jodi Benassi | Mar 26, 2026 | Patents

Addressing patent eligibility, infringement, willfulness, enhanced damages, and the limits of patent damages tied to foreign software sales, the US Court of Appeals for the Federal Circuit vacated a $185 million jury award after finding that damages based on foreign sales were improperly included because the accused software copies were made and installed abroad. Trs. of Columbia Univ. v. Gen Digital Inc., Case No. 24-1243 (Fed. Cir. Mar. 11, 2026) (Dyk, Prost, Reyna, JJ.)

The Trustees of Columbia University sued Gen Digital, the Norton software brand marketer, for infringement of patents directed to detecting anomalous program execution in antivirus software. A jury found willful infringement and awarded approximately $185 million in damages, including more than $94 million attributable to foreign sales of Norton software products based on findings that the infringing product sold to foreign customers was made in and distributed from the United States. The district court denied Gen Digital’s post-trial motions, enhanced the damages, and awarded attorneys’ fees. Gen Digital appealed.

Patent eligibility: Abstract at Alice step one

The Federal Circuit determined that the asserted claims are directed to an abstract idea at step one of the Alice framework. The Court explained that the claims, at their core, involve comparing data (function calls) to a model – created using multiple computers – to identify anomalous behavior, which is a long-standing abstract concept in the context of virus detection. Although Columbia argued that the claims improved computer functionality through efficiency gains and the use of distributed models, the Court found that those purported improvements were either themselves abstract or not required by the claim language. The Court agreed with Columbia that factual disputes remain as to whether certain claimed features – particularly the “model of function calls” – were well-understood, routine, and conventional, precluding resolution of step two of the Alice framework. The Court remanded for further proceedings to perform an Alice step two analysis.

Willfulness: Affirmed by substantial evidence

The Federal Circuit found that substantial evidence supported a finding that Gen Digital knew or should have known of the asserted patents, including evidence that its personnel were aware of the underlying technology and related patent applications prior to issuance. The Court rejected Gen Digital’s argument that its litigation defenses precluded willfulness, explaining that post hoc reasonable defenses do not negate willfulness absent evidence that the defendant relied on those defenses at the time of the accused conduct. Because the record supported a finding that Gen Digital failed to adequately investigate potential infringement despite being aware of the patents, the Federal Circuit found no basis to disturb the district court jury’s willfulness determination.

No domestic infringement for foreign-made software copies

The Federal Circuit reiterated the general rule that US patent law does not apply to products made and sold abroad. Although the jury was instructed that damages could include foreign sales if the infringing product was “made in or distributed from the United States,” the Court found this instruction legally incorrect. The Court further explained that 35 U.S.C. § [...]

Virtually displayed: USPTO updates guidance for computer-generated interfaces and icons

by Taylor MacDonald | Mar 26, 2026 | Patents

To address evolving digital technologies, the United States Patent and Trademark Office (USPTO) issued supplemental guidance for examining design patent applications directed to computer-generated interfaces and icons. The guidance expands flexibility for applicants – particularly in projection, hologram, and virtual and augmented reality (PHVAR) contexts – while maintaining the statutory requirement that claimed designs be tied to an article of manufacture.

The USPTO first sought public input in 2020 on how the “article of manufacture” requirement under 35 U.S.C. § 171 should apply to emerging digital designs. Although many commenters urged recognition of PHVAR designs, subsequent guidance issued by the USPTO in 2023 did not fully address those technologies. The latest supplemental guidance responds to continued stakeholder feedback, particularly regarding the limitations imposed by prior drawing requirements.

Traditionally, applicants seeking protection for computer-generated icons or graphical user interfaces (GUIs) were required to depict a physical article of manufacture, such as a display screen, in solid or broken lines in the drawings. This requirement ensured that the claimed design was not merely a “transient or disembodied” image but was instead tied to a statutory article of manufacture.

The updated guidance removes the requirement that drawings depict a display panel or other physical article, provided that the title and claim clearly identify the relevant article of manufacture (e.g., a computer, computer display, or computer system). In such cases, the article need not appear in the drawings, so long as the application, taken as a whole, makes it clear that the claimed design is “for” an article of manufacture and not merely an abstract or disembodied image. For example, phrases such as “interface for a computer system” or “icon for a display panel” are sufficient to establish that the design is tied to a qualifying article.

The USPTO reiterated that the guidance “does not constitute substantive rulemaking and hence does not have the force and effect of law.” Examiners will continue to evaluate applications under all applicable patentability provisions, including §§ 102, 103, and 112.

Overall, the updated guidance provides applicants with greater flexibility in claiming and depicting computer-generated designs while reaffirming that such designs must remain tied to a qualifying article of manufacture.

Absent a client waiver, attorney-client relationship survives conflict

by Connor M. Larson | Mar 26, 2026 | Patents

Reversing a district court order requiring the disclosure of attorney-client communications and holding a law firm in civil contempt, the US Court of Appeals for the Federal Circuit ruled that an attorney’s conflict of interest does not automatically terminate the attorney-client privilege and that an invalid order could not support civil contempt. Trs. of Columbia Univ. in City of New York v. Gen Digital Inc., Case No. 24-1243, (Fed. Cir. Mar. 11, 2026) (Dyk, Prost, Reyna, JJ.)

The Trustees of Columbia University sued Gen Digital, the Norton software brand marketer, for infringement of two patents and to correct the inventorship of one of the patents. Norton owned the patent on which inventorship correction was sought, and a Norton employee, Dr. Dacier, was listed as the sole inventor. Columbia alleged that two Columbia professors invented the subject matter.

On the inventorship issue, Norton and Dr. Dacier were both represented by Quinn Emanuel Urquhart & Sullivan. Dr. Dacier was deposed and testified about the development of the invention, including activities involving the Columbia professors. Dr. Dacier did not attribute any inventive contributions to the Columbia professors, but Columbia argued – and the district court agreed – that his testimony supported Columbia’s inventorship theory.

Before the district court, Columbia argued that this representation created an improper conflict of interest, particularly because Dr. Dacier had allegedly expressed views critical of Norton’s litigation positions. In Columbia’s view, Quinn Emanuel had improperly prevented Dr. Dacier from testifying at trial in support of Columbia’s inventorship claims. The district court agreed, finding that Quinn Emanuel’s representation of Dr. Dacier raised a conflict, and ruled that Quinn Emanuel’s current representation of Norton automatically terminated its representation of Dr. Dacier. The district court ordered Quinn Emanuel to release its communications with Dr. Dacier. Quinn Emanuel had previously asserted a claim of privilege over these communications. Quinn Emanuel refused the production order, and the district court found Quinn Emanuel in civil contempt. As a sanction, the district court imposed a negative evidentiary inference that Dr. Dacier would have testified to improper conduct by Quinn Emanuel – supporting Columbia’s motion for enhanced damages and attorneys’ fees in a companion case. Quinn Emanuel appealed.

On appeal, Quinn Emanuel argued that the district court’s order requiring the disclosure of communications with Dr. Dacier was invalid because it improperly compelled production of privileged communications and that the contempt finding should be reversed. Columbia argued that the disclosure order was proper because Norton did not raise the privilege issue response to Columbia’s motion for an order to show cause, Quinn Emanuel failed to request in camera review, Quinn Emanuel did not contact Dr. Dacier to determine if he wanted to assert privilege, and Dr. Dacier waived the privilege by emailing both Columbia’s counsel and Quinn Emanuel disclosing that he had been in contact with Columbia’s counsel.

The Federal Circuit rejected all four arguments, holding that there was “no question that Dr. Dacier retained Quinn [Emanuel] to represent him and that he did not terminate the relationship [...]

Corresponding disclosed structure? Only what’s necessary to perform a recited function

by Tyler Jackson | Mar 26, 2026 | Patents

The US Court of Appeals for the Federal Circuit held that the disclosure of an added function in the specification of a patent should not affect the structure necessary to meet the recited function in a Section 112(f) claim element. Gramm v. Deere & Co., Case No. 24-1598 (Fed. Cir. Mar. 11, 2026) (Lourie, Reyna, Cunningham, JJ.)

Richard Gramm exclusively licensed Reaper Solutions rights to a patent directed to an apparatus for keeping the header of a crop harvester at a certain height above the ground as the harvester moves across a field. Gramm and Reaper sued Deere & Co., alleging that specific Deere header sensor kits infringed the patent. Deere challenged the validity of the patent in a partially successful inter partes review (IPR) proceeding, leaving one independent claim and some of the dependent claims asserted.

In connection with claim construction during the IPR proceeding, Reaper and Deere disputed the meaning of “control means” in the independent claim. At issue was whether the specification’s discussion of the “head controller 20” was sufficiently definite corresponding disclosed structure for the (§112(f)) means-plus-function claim element to satisfy the definiteness requirement of §112 (b). The function of the claimed “head controller” was to provide electrical control signals to another feature in the claimed apparatus to control the lateral position of the corn header and its height above the ground or soil. Deere argued that “head controller 20” was not sufficiently definite since it amounted to a general-purpose computer or processor, thus requiring disclosure of code or an algorithm to avoid being indefinite.

In 1997, the patent’s priority date, there were only three commercially available head controllers used in Deere combines: Dial-A-Matic Versions #1, #2, and #3. Deere argued that only Versions #2 and #3 could constitute corresponding structure for the “head controller 20,” as only those versions could control both header height and lateral position. Because Versions #2 and #3 used microprocessors to control header height, Deere argued that the patent specification was required to disclose an algorithm for performing the claimed function. In the alternative, Deere argued that the district court should hold Reaper to its argument in the IPR proceeding that the corresponding disclosed structure was the specific controller incorporated into Deere’s Dial-A-Matic Version #1, which “controlled header height through a series of diodes, switches and integrated circuits rather than a microprocessor.”

The district court found the independent claim indefinite and reasoned that the specification’s reference to Dial-A-Matic Versions #2 and #3 triggered the need for a disclosure of a general-purpose computer or microprocessor that the patent failed to satisfy. The district court accepted Deere’s argument that the specification did not disclose Dial-A-Matic Version #1 as a corresponding structure because it could not perform the function of controlling the lateral position of the corn header. Reaper appealed.

The Federal Circuit agreed with Reaper that the district court erred by identifying a corresponding structure for “control means” beyond what was necessary to perform the claimed function, leading the district court to incorrectly [...]

Too late to help: Inventorship fix fails to revive forfeited argument

by Amit Kumar Saha, PhD | Mar 19, 2026 | Patents

The US Court of Appeals for the Federal Circuit affirmed the Patent Trial & Appeal Board, concluding that the retroactive effect of a correction of inventorship under 35 U.S.C. § 256 does not bar the application of forfeiture principles in inter partes review (IPR) proceedings, and that a patent owner that fails to timely raise an antedating theory during an IPR may forfeit reliance on a later corrected inventorship to resurrect that theory. Implicit, LLC v. Sonos, Inc., Case Nos. 20-1173; -1174 (Fed. Cir. Mar. 9, 2026) (Taranto, Stoll, Cunningham, JJ.)

Implicit owns patents directed to content rendering that originally named Edward Balassanian and Scott Bradley as co-inventors. Sonos filed IPR petitions against both patents, asserting unpatentability under 35 U.S.C. §§ 102 and 103, primarily based on Janevski, which had an effective prior art date of December 11, 2001.

To avoid Janevski as prior art, Implicit argued that the inventions were conceived and reduced to practice before December 11, 2001. It contended that Balassanian and Bradley conceived of the inventions and collaborated with another engineer, Guy Carpenter, to implement the invention prior to December 2001. Implicit argued that Carpenter’s work inured to the benefit of the named inventors, thereby antedating Janevski. The Board rejected Implicit’s argument and found the challenged claims unpatentable as anticipated or obvious over Janevski. The Board found Implicit’s evidence insufficient to establish conception and communication of the invention by Carpenter in a manner that would support an earlier reduction to practice.

Following the Federal Circuit’s and Supreme Court’s decisions in Arthrex v. Smith & Nephew addressing the Appointments Clause as applied to IPR proceedings, the case was remanded to permit Director review. While proceedings were ongoing, Implicit sought correction of inventorship under 35 U.S.C. § 256 to add Carpenter as a co-inventor. The United States Patent & Trademark Office (USPTO) granted the request and issued certificates of correction in August 2022. The Federal Circuit remanded the case to the Board to determine what impact, if any, the corrections had on the prior final written decisions. The Board concluded that equitable doctrines, including forfeiture, precluded Implicit from relying on the corrected inventorship to advance a new antedating theory. Implicit appealed.

The appeal presented two principal questions:

Whether the retroactive effect of a correction of inventorship under § 256 forecloses application of forfeiture principles in an IPR proceeding.
Whether the Board abused its discretion in finding that Implicit forfeited its right to assert a new antedating theory based on corrected inventorship.

Implicit argued that § 256 contains no temporal limitation and that corrections operate retroactively, requiring the Board to revisit its unpatentability determinations once Carpenter was added as an inventor. Sonos and the USPTO countered that Implicit had litigated the IPRs on a single inventorship theory and waited until after adverse final written decisions to change course.

The Federal Circuit affirmed on both grounds.

First, the Federal Circuit found that forfeiture principles may apply notwithstanding the retroactive effect of § 256. Although [...]
