Wooden Toy Patent Dispute Ends in Voluntary Dismissal: Lessons for Design Patent Enforcement

Introduction

A design patent infringement action filed in the U.S. District Court for the Northern District of Illinois concluded in voluntary dismissal just 48 days after filing — raising important questions about enforcement strategy, Schedule A litigation mechanics, and the practical limitations of pursuing anonymous e-commerce defendants. In Peixian JiYi Cat Trading Co. Ltd. v. The Partnerships and Unincorporated Associations Identified on Schedule A, Case No. 1:25-cv-01944, the plaintiff withdrew its claims without prejudice against the sole remaining defendant before any responsive pleading was filed. The case centered on wooden toy apparatus design patent infringement, specifically USPTO Design Patent No. USD1038258S. For patent attorneys navigating Schedule A litigation campaigns, IP professionals monitoring design patent enforcement trends, and R&D teams assessing freedom-to-operate risk in the toy products sector, this case offers concise but strategically meaningful lessons about early-stage infringement actions and their inherent procedural vulnerabilities.

Case Overview

The Parties

The Patent at Issue

This case centered on U.S. Design Patent No. USD1038258S, which protects the ornamental appearance of a wooden toy apparatus.

• • US D1038258S (Application No. US29/931251) — Wooden toy apparatus
• • **Patent Type:** U.S. Design Patent
• • **Scope:** Design patents protect the ornamental appearance of a product, not its functional features. The patent’s protected claims cover the specific visual design elements of a wooden toy, as reflected in the patent’s drawings registered with the USPTO.

The Accused Product

The complaint alleged infringement related to **wooden toy apparatus** products marketed through online platforms. Schedule A cases of this nature typically target sellers offering visually similar products on marketplaces such as Amazon, eBay, Walmart Marketplace, or Wish.

Legal Representation

• • **Plaintiff’s Counsel:** Depeng Bi and Konrad Val Sherinian of The Law Offices of Konrad Sherinian LLC
• • **Defendant’s Counsel:** None entered. The defendant did not appear, file an answer, or respond in any capacity.

Litigation Timeline & Procedural History

The action was filed on **February 25, 2025**, in the **U.S. District Court for the Northern District of Illinois** — the nation’s most prominent venue for Schedule A patent and trademark litigation.

The case was assigned to **Chief Judge Edmond E. Chang**. It closed after only **48 days** — a notably short lifespan consistent with Schedule A cases that resolve before any contested litigation phase begins.

The Verdict & Legal Analysis

Outcome

The case concluded through **voluntary dismissal without prejudice** pursuant to **Rule 41(a)(1) of the Federal Rules of Civil Procedure**. The plaintiff filed a notice of voluntary dismissal covering the sole remaining defendant, tukeqishangmao. Under Rule 41(a)(1), a plaintiff may dismiss an action without a court order by filing a notice of dismissal before the opposing party serves an answer or a motion for summary judgment. That condition was expressly satisfied here — the defendant had not appeared, answered, or moved in any capacity.

Each party was ordered to bear its own attorneys’ fees and costs. No damages were awarded, and no injunctive relief was granted or denied through contested proceedings.

Verdict Cause Analysis

The dismissal notice explicitly confirmed: *”Plaintiff respectfully submits that no more defendants remain in the case.”* This language indicates that tukeqishangmao was the final remaining defendant from the original or amended Schedule A, with all other defendants having been previously resolved, dismissed, or settled through confidential means not reflected in the public record.

The absence of any responsive pleading from the defendant is legally significant. Rule 41(a)(1) dismissal is a unilateral plaintiff right when exercised before the defendant answers — requiring no judicial approval and carrying no res judicata effect when filed without prejudice. This means the plaintiff retains the theoretical right to refile against tukeqishangmao or related parties in the future.

Legal Significance

This case does not produce binding precedent on substantive design patent law. However, it illustrates several procedurally significant patterns in Schedule A design patent litigation:

• 1. **Non-appearance by defendants** is common when defendants are anonymous marketplace sellers who may not receive actual notice, may be located overseas, or may choose to abandon the accused seller account rather than engage in litigation.
• 2. **Voluntary dismissal as an exit strategy** allows plaintiffs to close cases cleanly when a defendant cannot be served, identified, or monetized through settlement — avoiding default judgment proceedings that may yield uncollectable awards.
• 3. **Design patent USD1038258S** remains active and unadjudicated on validity or infringement grounds, preserving its full enforceability for future assertions.

Strategic Takeaways

For Patent Holders: Design patent Schedule A campaigns require robust defendant identification and service infrastructure. When defendants remain unreachable or non-monetizable, Rule 41(a)(1) dismissal without prejudice is a clean, low-cost exit that preserves future enforcement options.

For Accused Infringers: Non-appearance carries litigation risk even when a plaintiff ultimately dismisses. Sellers on e-commerce platforms should monitor for litigation filings against their seller accounts and engage counsel promptly. Platform-level account freezes can cause commercial harm well before any court-ordered relief is entered.

For R&D and Product Teams: Wooden toy and children’s product designers should conduct freedom-to-operate (FTO) analysis covering active U.S. design patents, including Design Patent USD1038258S (US29/931251), before commercializing visually similar products in U.S. markets.

Industry & Competitive Implications

The wooden toy and children’s educational product market has seen increased design patent activity as both U.S. and Chinese manufacturers seek to differentiate ornamental product designs amid intense e-commerce competition. The Schedule A litigation model — aggregating multiple online marketplace sellers into a single action — has become a dominant enforcement mechanism in this space, particularly in the Northern District of Illinois.

This case reflects a broader trend: Chinese IP rights holders increasingly filing offensive U.S. patent and trademark litigation to protect designs against copycat sellers, inverting the conventional narrative of Chinese manufacturers as defendants in U.S. IP proceedings.

The rapid 48-day closure also signals a market reality — many Schedule A defendants dissolve their seller accounts upon receiving notice, eliminating the economic justification for continued litigation. For competitors in the wooden toy space, this case reinforces the importance of maintaining clear design differentiation from registered U.S. design patents and monitoring new USPTO design patent grants in adjacent product categories.
