Dongguan Saien Chuangke Technology Co. Ltd. v. Shenzhen Huamingjun Rubber, No. 26-cv-6539, (N.D. Ill. Aug. 28, 2026).

The parties in this design patent case filed a joint motion for entry of a consent judgment and permanent injunction in which defendant Shenzhen Huamingjun Rubber Co. Ltd. (“SHR”) conceded that plaintiffs Dongguan Saien Chuangke Technology Co. Ltd.’s (“DSCT”) and Zuru Inc.’s design patents covering magnetic reusable water balloons, U.S. Patent Nos. D1,030,929 and D1,101,076, are valid, enforceable, and infringed by all past and present versions of SHR’s reusable balloon products.

Of particular interest, the proposed consent judgment does not stop at liability. SHR also stipulated to facts supporting each of the four eBay permanent injunction factors: irreparable harm through lost market share, price erosion, and lost goodwill; the inadequacy of legal remedies; a balance of hardships favoring plaintiffs; and a public interest that would not be disserved because adequate non-infringing substitutes are available. The proposed order includes corresponding proposed  findings by the Court.

The proposed injunction would bar SHR, its affiliates, and any internet sellers it controls from making, using, selling, offering to sell, or importing reusable balloon products that are colorable imitations of, or have substantially the same overall design as, the patented designs. Each party bears its own costs and fees, and the Court retains jurisdiction to enforce the order.

This is a useful example of how parties can build a record supporting injunctive relief into a settlement. It is also the second consent judgment between these parties. See the related 24-cv-8111 consent judgment between these parties discussed below.
