Court Dismisses Artist's Flaming Skull Suit
A federal judge in Missouri tossed copyright and trademark claims brought by artist John Ketner against motorcycle parts maker Cioni Inc.
Updated on Nov. 2, 2026 in Auto Parts

The U.S. District Court for the Eastern District of Missouri dismissed artist John Ketner's copyright and Lanham Act claims against Cioni Inc. on October 15, and declined supplemental jurisdiction over his remaining state law claims. Ketner had accused the St. Louis motorcycle parts manufacturer of using a flaming skull design similar to his sculptural work.
Why it matters
The ruling shows that a copyright claim over a similar design can fail when the plaintiff cannot plausibly show the defendant had access to the original work. For St. Louis businesses and artists, it underscores the evidentiary burden in design disputes.
The court ruled on October 15, 2026, and Ketner holds a copyright registration but no federal trademark for the flaming skull design. The court found the designs substantially similar but not strikingly similar or virtually identical.
The players
John Ketner
A professional artist known for sculptural flaming skull designs, who brought the suit claiming his copyrighted work was copied.
Cioni Inc.
A motorcycle parts manufacturer based in St. Louis, described by its attorney as a small, family-owned business.
The details
Ketner, a professional artist who creates sculptural flaming skull designs, sued Cioni after alleging its motorcycle parts used a similar design. The court found he failed to plead that Cioni had access to his work and that his claims of widespread dissemination were conclusory, and it held his Lanham Act claim sounded in copyright rather than trademark. Ketner had sent Cioni a cease-and-desist letter before filing suit.

Legal Context
The decision follows the federal framework that separates copyright claims, which require proof of access and substantial similarity, from Lanham Act claims, which require a trademark and consumer confusion. Courts applying that framework have consistently required plaintiffs to tie a design dispute to the statute that actually protects it.
Parts makers and designers in St. Louis may need to document how their designs were created and who had access to them before entering a dispute. Consumers buying aftermarket motorcycle parts are not directly affected by the dismissal.
The takeaway
Artists who want to challenge a similar design should be prepared to show the defendant had access to the original work, not just that the designs look alike. Businesses should keep records of their design development to defend against similar claims.
