The patent and the design

The patent is U.S. Design Patent D1,053,273, "Fidget Toy," issued December 3, 2024 from Application No. 29/940,018, filed April 30, 2024. The complaint says its single claim covers the ornamental design for a fidget toy as shown in five figures, and that the roof and conical turrets are drawn in broken lines and so form no part of the claimed design. The plaintiff's product is the "Bouncy Blast Multi-Pack," a keychain clicker fidget housing a mechanical keyboard switch and styled after an inflatable play castle, which the complaint says was released on or about March 25, 2026 and created independently. The complaint says the plaintiff sells the digital files and does not itself make physical units, which are printed by consumers and by roughly 2,050 licensees.

What the complaint alleges

The complaint alleges that in July 2026 the defendant sent written demands asserting infringement and seeking a license, and that after the plaintiff rejected them on July 17, 2026, following review by patent counsel, he contacted at least one licensee on October 16, 2026, said he owned a trademark in BOUNCE HOUSE FIDGET, said that Etsy was being put on notice, and threatened to name the licensee in a lawsuit unless it removed the product within five business days. It says the demands omitted the patent number, apart from a photograph of the patent provided on request, and identified no claim or accused feature. It alleges that statements the defendant made to the licensee about the plaintiff were false when made, and, on information and belief, that he owned no trademark registration or pending application for the phrase on October 16, 2026. The complaint says he filed U.S. Trademark Application Serial No. 50177875 for BOUNCE HOUSE FIDGET and Design on October 23, 2026.

It pleads eight causes of action: declaratory judgment of non-infringement of the '273 design patent; declaratory judgment of no trademark infringement under 15 U.S.C. §§ 1114 and 1125(a); bad faith assertion of patent infringement under Utah Code Ann. § 78B-6-1901 et seq.; intentional interference with economic relations; injurious falsehood; defamation; false or misleading representation of fact under 15 U.S.C. § 1125(a)(1)(B); and deceptive trade practices under the Utah Truth in Advertising Act. Diversity jurisdiction is pleaded in the alternative.
