GZ Long Ya Trading Co., Ltd. v. The Partnerships and Unincorporated Associations Identified on Schedule A, No. 24-cv-4193, (N.D. Ill. Apr. 24, 2026) (Holleb Hotaling, Mag. J.).
Magistrate Judge Holleb Hotaling granted plaintiff GZ Long Ya Trading’s motion for summary judgment and permanent injunctive relief against the remaining Schedule A defendant Tonchean, denied plaintiff’s request for attorneys’ fees, and ordered supplemental briefing on damages in this design patent infringement case involving U.S. Design Patent No. D986,339, directed to an ornamental design for a puzzle table.
Of particular interest, the Court held:
- Defendant failed to properly dispute plaintiff’s Local Rule 56.1 statement of undisputed material facts. Although Defendant filed a response, it failed to cite specific evidentiary material controverting the asserted facts, merely stating certain facts were disputed because “the licensee has a different name from that of the Plaintiff” or that certain evidence was “self-serving.” All properly supported facts were therefore deemed admitted.
- The Court rejected Defendant’s standing challenge based on the difference between “GZ Long Ya Trading Co., Ltd.” and the assignment’s reference to “Guangzhou LongYa Trading Co. Ltd.” The Court found “GZ” is a common abbreviation for “Guangzhou,” and the inventor’s sworn declaration confirmed the assignment to plaintiff. Plaintiff had standing as sole assignee.
- The ’339 Patent was valid despite containing functional features. The Court held that the existence of functional elements does not itself invalidate a design patent; rather, the claimed design must be viewed in its entirety. The shape of the tabletop, symmetrically arranged drawers, side placement of drawers, leg shape, and connecting bar placement were all ornamental features entitled to protection. Defendant conceded alternative designs exist, further supporting validity.
- Infringement was established both by deemed admissions (Defendant served discovery responses more than three months late) and, independently, under the ordinary observer test. The Court’s side-by-side comparison found the accused Wayfair puzzle tables were substantially similar to the patented design, with the only identified difference being two additional drawers beneath the top flipped table.
- The Court granted permanent injunctive relief, applying the same irreparable-harm findings that supported the earlier preliminary injunction: diminished goodwill, damage to reputation, loss of exclusivity, and loss of future sales.
- The Court denied attorneys’ fees under 35 U.S.C. § 285 because plaintiff had not shown the case was exceptional, notwithstanding Defendant’s late discovery responses and Local Rule noncompliance.
- The Court requested supplemental briefing on whether plaintiff seeks more than $55,300 in damages and the basis for any additional amount.
