Extraterritoriality

Pay up, per party litigation stipulation

by Lauren Hong | Apr 23, 2026 | Patents

The US Court of Appeals for the Federal Circuit revived key portions of a long-running patent dispute, rejecting the district court’s extraterritoriality ruling and narrowing its prosecution disclaimer analysis while leaving intact the exclusion of certain damages theories for inadequate disclosure. VLSI Technology LLC v. Intel Corporation, Case No. 24-1772 (Fed. Cir. Apr. 15, 2026) (Moore, Chen, Kleeh, JJ.)

VLSI filed suit in 2017 accusing Intel of infringing several patents related to selecting an appropriate core in a multicore processor to execute a task based on measured performance characteristics. Following claim construction and discovery, the district court struck portions of VLSI’s damages case, concluding that certain theories advanced by VLSI’s damages expert had not been adequately disclosed. The court then granted summary judgment of noninfringement on two independent grounds: extraterritoriality on the theory that the claimed “measuring” activity occurred outside the United States, and failure of VLSI’s doctrine of equivalents arguments. VLSI appealed.

The Federal Circuit reversed in substantial part. As to the asserted method claims, the Federal Circuit concluded that the district court’s extraterritoriality analysis could not be reconciled with the parties’ stipulation. That stipulation provided that, for accused Intel products and activities meeting the technical requirements of the asserted claims, 70% would be deemed to satisfy the requisite US nexus for infringement purposes. The district court had reasoned that the stipulation could not establish domestic infringement unless the underlying claim limitations themselves were practiced in the United States. The Federal Circuit disagreed, emphasizing the stipulation’s plain language that the technical requirement inquiry was to be conducted “without regard to geographic considerations.”

The Federal Circuit rejected Intel’s contention that the stipulation merely served as a damages accounting shortcut rather than as an agreement bearing on infringement. However, in the Court’s view, stipulating a fact relevant to infringement, such as US nexus, is different from conceding infringement itself. The Court therefore found that Intel was bound by the agreement it struck, even if it later came to view the agreement as “imprudently made.”

On that basis, the Federal Circuit reversed the grant of summary judgment of noninfringement on extraterritoriality grounds for the asserted method claims.

The Federal Circuit also reversed summary judgment as to the asserted apparatus claims. It concluded that the district court had focused too narrowly on where the claimed measuring functionality was practiced, rather than on whether the accused products were reasonably capable of performing the claimed functions without significant alteration. The Court concluded that the record contained sufficient evidence to create a genuine dispute of material fact as to whether the accused products were reasonably capable of performing the claimed measuring limitations. Summary judgment was therefore inappropriate, and the Court reversed the extraterritoriality ruling as to the apparatus claims.

The Federal Circuit also reinstated VLSI’s doctrine of equivalents theory for some of the apparatus claims that the district court had barred based on a prosecution disclaimer finding. Referencing the prosecution of the asserted patent, the district court imported an “upon identifying” limitation into the claims, notwithstanding [...]

Equity Is Neither a “Good” Nor a “Service” Under Lanham Act

by Cecilia Choy, PhD | Jan 16, 2025 | Trademarks

The US Court of Appeals for the Ninth Circuit affirmed a district court’s decision that, in terms of trademark use in commerce, corporate equity is not a “good” or “service” under the Lanham Act. LegalForce RAPC Worldwide, PC v. LegalForce, Inc., Case No. 23-2855 (9th Cir. Dec. 27, 2024) (Thomas, Wardlaw, Collins, JJ.) (Collins, J., concurring).

LegalForce RAPC Worldwide is a California corporation that operates legal services websites and owns the US mark LEGALFORCE. LegalForce, Inc., is a Japanese corporation that provides legal software services and owns the Japanese mark LEGALFORCE.

Both parties had discussions with the same group of investors. After those meetings, LegalForce Japan secured $130 million in funding, while LegalForce USA received nothing. Thereafter, LegalForce USA brought several claims against LegalForce Japan, including a trademark infringement claim. To support its case, LegalForce USA cited LegalForce Japan’s expansion plan, a trademark application for the mark LF, website ownership, and the use of LEGALFORCE to sell and advertise equity shares to investors in California.

The district court dismissed claims related to the website for lack of personal jurisdiction and dismissed claims related to the US expansion plan, trademark application, and alleged software sales in the United States as unripe. The district court dismissed the trademark infringement claims related to the efforts to sell equity shares for failure to state a claim. The court found that advertising and selling equity cannot constitute trademark infringement because it is not connected to the sale of goods or services, and the case did not present justification for extraterritorial application of the Lanham Act. LegalForce USA appealed.

To state a claim for trademark infringement under the Lanham Act, plaintiffs must show that:

They have a protectible ownership interest in the mark, or for some claims, a registered mark
The defendant used the mark “in connection with” goods or services
That use is likely to cause confusion. 15 U.S.C. § 1114(1)(a), § 1125(a).

The Ninth Circuit agreed with the district court that LegalForce Japan had not used LegalForce USA’s mark “in connection with” goods or services, and thus LegalForce USA failed to state a claim for which relief could be granted.

The Ninth Circuit concluded that using LEGALFORCE to advertise and sell equity failed to satisfy the requirement that a defendant used the mark in connection with goods or services. Referring to the U.C.C., the Court explained that corporate equity is “not a good for purposes of the Lanham Act, because it is not a movable or tangible thing.” Equity is also not a service because it is not a performance of labor for the benefit of another. There is no “another” involved because those who buy LegalForce Japan equity are owners and so they are not legally separate “others.”

The Ninth Circuit also agreed with the district court that LegalForce Japan’s services in Japan did not satisfy the “in connection with” goods or services requirement under the Lanham Act. To determine when a statute applies extraterritorially, courts invoke the 2023 Supreme Court

Reasonable Royalty Available for Foreign Activities (But Not This Time)

by Amol Parikh | Apr 11, 2024 | Patents

The US Court of Appeals for the Federal Circuit affirmed a district court’s decision to preclude a patent owner from seeking damages based on method claims infringed outside of the United States but confirmed that reasonable royalties are available based on foreign activities. Harris Brumfield v. IBG LLC, Case No. 22-1630 (Fed. Cir. Mar. 27, 2024) (Prost, Taranto, Hughes, JJ.)

Trading Technologies International (TT), whose successor is Harris Brumfield, filed a lawsuit against IBG in 2010 alleging infringement of four patents directed to graphical user interfaces for commodity trading and methods for placing trade orders using those interfaces. During the underlying proceeding, the district court issued several orders. The district court granted IBG’s motion for summary judgment that the claims of two of the patents were invalid. The district court also excluded one of TT’s damages theories concerning foreign activities. Prior to trial, the district court found that two of the patents were invalid as patent ineligible and that the other two patents contained patent eligible subject matter. The district court also excluded one of TT’s damages theories concerning foreign activities.

The case proceeded to trial on the two remaining patents, and the jury found the asserted claims of those two patents infringed. IBG proposed $6.6 million in damages, which corresponds to the total demanded by IBG using IBG’s proposed royalty rate measured against domestic usage, rather than global users. By contrast, TT proposed damages of $962 million, which included all worldwide users of the accused product, regardless of whether they performed the claimed method. The jury agreed with IGB and awarded TT $6.6 million. the district court denied TT’s post-verdict motion for a new trial on damages, a motion in which TT alleged that IBG had misrepresented how it calculated the damages figures it presented to the jury. TT appealed.

Under the Supreme Court’s 2018 decision in WesternGeco v. Ion Geophysical, a patent owner can recover damages in the form of foreign lost profits when infringement is found under 35 U.S.C. § 271(f)(2) of the Patent Act. TT argued that under WesternGeco, it can seek damages in the form of a reasonable royalty based on IBG “making” the accused product in the US, even though the products were used overseas. The Federal Circuit engaged in a detailed description of WesternGeco, concluding that the Court must examine the particular acts alleged to constitute infringement under particular statutory provisions to determine if the allegations focus on domestic conduct. The Court explained that under § 271(a), the making, using, offering to sell and selling provisions are limited to domestic acts. The Court acknowledged that the WesternGeco framework applies to reasonably royalty awards (not just lost profits) and that a reasonable royalty would be the amount a hypothetical infringer would pay to engage in the domestic acts constituting the infringement.

Despite finding that reasonable royalties are permitted under WesternGeco, the Federal Circuit affirmed the district court’s exclusion of TT’s damages theory because TT’s infringement theory about making the accused product [...]

US-China Agreement Supports International Injunction Against Alleged Chinese Counterfeiter Under State Law

by Paul Devinsky | Feb 4, 2021 | Trade Secrets

Addressing for the first time whether state law has extraterritorial scope, the US Court of Appeals for the Sixth Circuit upheld a worldwide preliminary injunction against an alleged Chinese counterfeiter’s use of alleged trade secrets, citing a new US-China trade agreement. AtriCure, Inc. v. Meng, Case No. 20-3264 (6th Cir. Jan. 21, 2021) (McKeague, J.)

AtriCure is an Ohio company that sells surgical tools for the treatment of atrial fibrillation. AtriCure needed a Chinese agent to register and sell its product in China. Dr. Meng became AtriCure’s distributor in China from 2005 to 2017. After Meng signed multiple distribution agreements with AtriCure, including non-compete clauses and confidentiality agreements, he was given access to confidential technical documents describing AtriCure’s products. Unbeknownst to AtriCure, Meng was the president of AtriCure’s Chinese competitor, Med-Zenith. When Med-Zenith released a line of products that were strikingly similar to AtriCure’s in both form and operation, AtriCure sued for trade secret misappropriation under the Ohio Uniform Trade Secrets Act and sought a worldwide preliminary injunction to prevent Meng from continuing to manufacture and sell counterfeit versions of AtriCure’s medical devices. After the district court granted the preliminary injunction, Meng appealed.

Addressing Meng’s arguments on likelihood of success, the Sixth Circuit found that:

The district court defined the alleged trade secrets with sufficient specificity because AtriCure had given Meng detailed drawings and manufacturing specifications.
The district court had not clearly erred in relying on evidence that AtriCure provided the trade secret information to Meng or that Meng used the information where Med-Zenith had copied its entire product line from AtriCure.
The district court had not clearly erred in holding that the production of an adapter that did not copy but still took advantage of AtriCure’s proprietary algorithm (i.e., by allowing Med-Zenith accessories to be used with AtriCure’s system) was likely a misappropriation of trade secrets.

Addressing the extraterritorial aspect of a worldwide injunction, the Sixth Circuit held that the district court did not abuse its discretion in issuing a worldwide injunction because the international reach of the injunction comports with the equities of the case and does not offend international comity. As to the equities, the Court noted that worldwide injunctions are common in trade secret misappropriation cases. As to comity, the Court found that Meng had failed to articulate any conflict and cited a recently signed agreement between the United States and China that “emphasizes trade secret protection” (Economic and Trade Agreement Between the Government of the United States of America and the Government of the People’s Republic of China, Jan. 15, 2020).

Finally, the Court addressed whether the Ohio Uniform Trade Secrets Act itself was entitled to extraterritorial scope. Because Ohio courts had not yet addressed the question, the Court conducted its own statutory interpretation and found that the intent of the statute (“the lodestar of statutory interpretation in Ohio”) favored extraterritorial application “at least in this case.”
