Dmarcian, Inc. v. DMARC Advisor BV

Judge: J. Harvie Wilkinson
Opinion Date: July 10, 2026

An American software company based in North Carolina and a Dutch company entered into a business relationship that later soured. The American company alleged that the Dutch company stole its brand name, software code, and customer base. The Dutch company operated a website nearly identical to the American company’s, using its name, logo, and marketing materials, and targeted American customers, even convincing at least one U.S. company to switch providers. Disputes between the parties also led to reciprocal lawsuits in both the United States and the Netherlands, with overlapping subject matter.

The United States District Court for the Western District of North Carolina initially issued a preliminary injunction against the Dutch company, finding the American company was likely to succeed on its copyright, trademark, trade secret, and tortious interference claims. After the Supreme Court’s decision in Abitron Austria GmbH v. Hetronic International, Inc. altered the standard for the extraterritorial application of the Lanham Act, the district court modified its injunction to comply with the new “conduct-focused” approach and dismissed the copyright claim. The district court also ordered the Dutch company to correct statements made to the Dutch court and later held the company in civil contempt for failing to comply fully, imposing a monetary sanction.

The United States Court of Appeals for the Fourth Circuit reviewed the case. Applying the Supreme Court’s new guidance from Abitron, the Fourth Circuit affirmed the second amended preliminary injunction, holding that the Dutch company’s conduct constituted infringing use in U.S. commerce under the Lanham Act, and that the Defend Trade Secrets Act’s express extraterritorial provision was satisfied by acts in furtherance of misappropriation occurring in the United States. The court dismissed the appeals from the correction and contempt orders for lack of appellate jurisdiction. View “Dmarcian, Inc. v. DMARC Advisor BV” on Justia Law
