CrossFit Files Trademark Infringement Suit Against CrossFit NV and Owner Harper

CrossFit, LLC filed a trademark infringement suit against CFNV, CrossFit N.V., CrossFit NV, CrossFit Nova Vita and owner William T. Harper in the U.S. District Court for the District of New Hampshire, listing case number 1:26-cv-00005 before Judge Talesha L. Saint-Marc. The public docket shows the action was opened with an 18-page complaint and a jury demand on January 6, 2026.

Pacermonitor’s docket entry for the initial filing reproduces the complaint filing language: "NEW CASE/ COMPLAINT with Jury Demand Filing fee $ 405, receipt number ANHDC-2724760 filed by Crossfit, LLC.. Complaint includes a claim under the NH Consumer Protection Act. A copy of the Complaint has been sent to the NH Attorney General via an automatic Notice of Electronic filing. (Christensen, Jeffrey) Related: [-]." The complaint was submitted by attorney Jeffrey Christensen and attaches a civil cover sheet and a summons-waiver for William T. Harper.

Also on January 6, CrossFit, LLC filed a corporate disclosure statement. The docket text records: "Disclosure Statement by Crossfit, LLC disclosing no parent company, no publicly traded company, and no merger agreement. (Christensen, Jeffrey) Related: [-]." That filing follows the complaint’s receipt transaction identified as ANHDC-2724760 and the $405 filing fee.

Defendant filings began appearing in early February. On February 5, 2026 the docket records a Notice of Attorney Appearance: "NOTICE of Attorney Appearance by Darrin R. Brown on behalf of William T. Harper Attorney Darrin R. Brown added to party William T. Harper (pty:dft).(Brown, Darrin) Related: [-]." Later that same day, counsel for Harper filed a motion seeking more time to respond; Pacermonitor preserves the motion text verbatim: "MOTION to Extend Time to Answer to February 12, 2026 filed by William T. Harper.Follow up on Objection on 2/19/2026. The court only follow up date DOES NOT include 3 additional days that may apply per FRCP 6(d) and FRCrP 45(c).(Brown, Darrin) Related: [-]."

CrossFit added an exhibit to the complaint on February 6; the docket entry reads: "Exhibit A to1 Complaint - New Case,, by Crossfit, LLC.(Christensen, Jeffrey) Related: [-]." Pacermonitor’s case page shows a broader maintenance timestamp as well: "Docket last updated: 02/18/2026 11:59 PM EST," while the case header also lists a "docket last checked: Tuesday, January 06, 2026 3:02 PM EST."

Law360’s case listing echoes the same basic metadata, case number 1:26-cv-00005, New Hampshire District Court, Judge Talesha L. Saint-Marc and the nature of suit classified as trademark, and displays standard subscription language about its archive that notes it "Reflects complaints, answers, motions, orders and trial notes entered from Jan. 1, 2011."

The supplied docket excerpts do not show whether the February 5 motion to extend was granted or whether an answer has been filed. Filings identify attorneys Jeffrey Christensen for CrossFit, LLC and Darrin R. Brown for William T. Harper; the complaint’s inclusion of an NH Consumer Protection Act claim and the jury demand are explicit on the record.
