Choon's Design LLC v. JOVA US INC, No. 1:26-cv-01451 (D. Del.), is a patent complaint filed November 11, 2026. The complaint says Choon's Design is a Michigan limited liability company based in Farmington Hills, Michigan, and the maker of Rainbow Loom rubber band crafting kits. It alleges, upon information and belief, that JOVA US INC is a Delaware corporation, and it says Delaware Division of Corporations records identify the company as a domestic Delaware corporation incorporated on August 11, 2023. The complaint demands a jury trial and seeks a preliminary and permanent injunction, damages, enhanced damages, attorney's fees and costs, and pre- and post-judgment interest.

The patents

U.S. Patent 8,899,631, Brunnian Link Making Device and Kit, issued December 2, 2014. U.S. Patent 9,750,317, Hand Held Link Making Device and Kit, issued September 5, 2017. The complaint says Choon's Design owns both patents by assignment. On December 11, 2024, the USPTO issued Reexamination Certificate No. US 8,899,631 C1 in Reexamination Control No. 90/019,235. The certificate confirms the patentability of claims 7 through 19, determines that claims 1, 4, and 20 are patentable as amended, determines that claims 3, 5-6, and 21-24, dependent on an amended claim, are patentable, and cancels claim 2. The complaint says references to the '631 claims are to the claims as they appear in that certificate, and it asserts at least claims 1, 4, 10, 13, 14, 20, and 24 of the '631 patent and at least claims 1, 2, 3, and 7 of the '317 patent.

As amended, claim 1 of the '631 patent covers a device for creating an item consisting of a series of links, comprising a template including at least two pins spaced apart from each other, each pin including a first end, a base end, an access groove, and a bridge portion extending between the base end of each of the pins, wherein the first end includes an outwardly extending flange and is interrupted by the access groove. As amended, claim 4 covers a device for creating an item consisting of a series of links, comprising a template including at least two pins spaced apart from each other, each including a first end, a base end, and an access groove, and a bridge portion extending between the base end of each of the pins, wherein the first end includes an outwardly extending flange and each of the access grooves extend entirely through each of the pins, including the first end and the base end. Claim 10 covers a kit comprising such a template, with at least two pins each including a first end, a base end, and an access groove, and at least one clip including inward facing ends for securing ends of the series of links together. Claim 13 adds a hook for manipulating elastic members relative to each other, and claim 14 adds a plurality of elastic members for forming the series of links. Claim 24 depends from claim 4 and adds a hook for manipulating elastic links supported on the template. As amended, claim 20 covers a kit for creating an item consisting of a series of links, comprising a template including at least two pins spaced apart from each other, each including a first end, a base end, and an access groove, and at least one clip including inward facing ends for securing ends of the series of links together, wherein the first end includes an outwardly extending flange. Claim 1 of the '317 patent covers a kit comprising a plurality of elastic bands, each a closed loop, and a template including at least two posts spaced apart from each other in a first direction, each post including a longitudinal channel bounded on three sides, a first tab near a top portion, and a second tab near a bottom portion, for holding an elastic band across the posts. Claim 2 adds at least one connector for securing an elastic band on one end of the series of links to another elastic band on the second end, claim 3 adds a base supporting the posts and defining an open space between them, and claim 7 adds a hook for manipulating elastic bands held between the posts.

The accused products

The complaint accuses a kit marketed under the Klever Kits brand as the Glow in the Dark Loom Bracelet Making Kit, Model No. 60270, which it says includes a hand-held mini-loom commonly called a Y-loom, together with hooks, clips, and rubber bands. It alleges Jova sells the kit in the United States through at least a JOVA Direct storefront on Amazon.com and a Jova US Inc storefront on Walmart.com, and alleges, upon information and belief, that Jova also offers and sells the accused products through the website jovatoys.com. It alleges, upon information and belief, that Jova has known of the asserted patents, and that the accused products infringe them, since before this complaint was filed. It separately alleges that Jova has had actual knowledge of the patents at least as of service of the complaint and that its continued infringement after that date is knowing, deliberate, and willful. The complaint identifies three earlier Eastern District of Michigan cases in which it says Choon's Design enforced the asserted patents: No. 4:22-cv-12963, No. 4:24-cv-13321, and No. 2:25-cv-14085.

The counts and the prayer

Count I alleges direct infringement of the '631 patent under 35 U.S.C. § 271(a), including at least claims 1, 4, 10, 13, 14, 20, and 24, literally or under the doctrine of equivalents, and alleges that the infringement has been willful and deliberate. Count II alleges the same under § 271(a) for the '317 patent, including at least claims 1, 2, 3, and 7. The prayer asks for judgment of infringement and of willfulness; a preliminary and permanent injunction under 35 U.S.C. § 283; an order that Jova deliver up for destruction, or certify the destruction of, all accused products and materials used in making or promoting them that are in its possession, custody, or control; damages of no less than a reasonable royalty, with an accounting of sales, under 35 U.S.C. § 284; enhanced damages of up to three times under § 284; a declaration that the case is exceptional and an award of reasonable attorneys' fees under 35 U.S.C. § 285; costs and expenses; pre-judgment and post-judgment interest; and further relief the court deems just and proper.
