Fourth Circuit Affirms Injunction in dmarcian Trademark Dispute

A panel of the U.S. Court of Appeals for the Fourth Circuit affirmed a North Carolina district court’s preliminary injunction against DMARC Advisor BV in a dispute involving trademark infringement, trade secret misappropriation, and related claims. The court found that the Dutch company’s conduct targeting U.S. commercial activity supported the injunction. The panel vacated a civil contempt sanction against the defendant’s attorney, holding that the plaintiff failed to demonstrate harm from noncompliance with a court order.

The underlying case centers on allegations that the Dutch entity improperly used branding, code, and trade secrets belonging to dmarcian Inc. The July 10, 2026, opinions represent the latest development in ongoing cross-border litigation between the parties.

The ruling clarifies the scope of personal jurisdiction and injunctive relief in intellectual property matters involving foreign defendants with U.S. ties.
