Flycatcher Sues Skriver Over Caydo Kids Drawing Projectors on Its Interactive Educational Toy Patent.

The complaint

Flycatcher Corp. Ltd. v. Skriver International Trading Limited, No. 2:26-cv-13183 (C.D. Cal.), was filed November 10, 2026, ECF No. 1 (8 pages), with a jury demand. The complaint describes Flycatcher as a United Kingdom private limited company based in London and Skriver as a Chinese company with its principal place of business in Hong Kong that sells products under the name CAYDO. It pleads jurisdiction under 28 U.S.C. 1331 and 1338(a), personal jurisdiction based on sales and shipments into the district, including through Amazon.com and the caydo.com website, and alternatively under Federal Rule of Civil Procedure 4(k)(2), and venue under 28 U.S.C. 1391(b)(3) and/or 1400(b). Flycatcher asserted the same patent in an earlier suit in the same court, No. 2:26-cv-11817, filed October 9, 2026.

The patent

U.S. Patent 12,688,791, titled Interactive Educational Electronic Toy System, issued July 21, 2026, from Application No. 17/685,461, filed March 3, 2022, and lists Flycatcher Corp LTD as applicant and assignee. The complaint alleges that Flycatcher owns the patent and describes it as generally directed to a system and method for providing a drawing challenge to a user.

Claim 1 covers a system for providing a drawing challenge made up of challenge steps, step by step, with a housing; a user interface in the housing with physical buttons, including a next-step button; at least one projecting device in the housing that projects each challenge step onto a projection surface in sequence; and a controller with a processor and stored instructions. The instructions interpret user input, receive a selection of a drawing or writing challenge whose steps each include one or more lines or curves, process the challenge based on characteristics of the projecting device, the projection surface, or ambient conditions to form projectable steps, provide the first step for projection, and, when the next-step button is pressed, provide the next step in the sequence.

The accused products

The complaint alleges that Skriver makes, uses, sells, offers for sale, and/or imports the Caydo T3 Joy Kids Drawing Projector and the Caydo T3 Art Projector, along with the Caydo Art Design App designed for use with them, and that the projectors compete directly with Flycatcher's smART Sketcher 2.0 and smART Sketcher AI projectors, which it says the patent covers. It cites claim charts, Exhibits D and E, for claim 1 against the two projectors, and the product manuals as Exhibits B and C.

The count and relief

The single count alleges that Skriver directly infringes at least claim 1 under 35 U.S.C. 271(a), literally or under the doctrine of equivalents; induces infringement by customers and end users under 271(b), through the manuals and other instructions; and contributes to infringement under 271(c), alleging that the projectors and systems have no substantial non-infringing use. For the indirect theories it alleges knowledge of the patent since at least the filing of the complaint. The prayer asks for a judgment of infringement; damages; a preliminary and permanent injunction requiring Skriver to stop infringing and to take down all offerings of the accused product; costs, expenses, and pre- and post-judgment interest; a finding of willfulness with enhanced damages up to treble damages; a finding that the case is exceptional under 35 U.S.C. 285 with attorneys' fees; and other relief.

What to watch next

Watch for service on Skriver, which the complaint describes as based in Hong Kong, for its response, and for any motion for a preliminary injunction.
