A patent infringement action involving a seemingly straightforward consumer product — a hat rack designed for baseball caps — reveals a sophisticated procedural maneuver that IP litigators should study closely. Filed on September 16, 2025, in the U.S. District Court for the Northern District of Illinois before Chief Judge Jeffrey I. Cummings, Changtingxiantinghaoshengshangmaoyouxiangongsi v. Zhongyi Jiang (Case No. 1:25-cv-11201) closed just 129 days later on January 23, 2026. The case’s resolution centered not on a merits verdict but on a motion to consolidate with a related Schedule A litigation already pending in the same district. For patent attorneys navigating multi-defendant enforcement campaigns and IP professionals tracking consumer goods patent litigation trends, this case offers a compelling blueprint for coordinated enforcement strategy.
Case Overview
The Parties
⚖️ Plaintiff
A Chinese commercial entity, consistent with the wave of Chinese manufacturing and e-commerce companies actively asserting U.S. patents.
🛡️ Defendant
An individual defendant, a common pattern in Schedule A-style litigation targeting sellers across online marketplaces.
The Patent at Issue
The litigation centers on a utility patent covering a **hat rack for baseball caps**. This product category has seen a notable uptick in IP enforcement activity, reflecting the broader proliferation of functional consumer storage and organization products sold through e-commerce channels. The patent claims cover the structural and functional design elements that distinguish this baseball cap storage solution in a competitive marketplace.
- • U.S. Patent No. US12220071B1 (Application No. US18/794524)
The Accused Product
The accused product — a hat rack for baseball caps — is a consumer household organization item sold through online retail platforms. Patent enforcement in this category is commercially significant: counterfeit or infringing hat storage products can undercut legitimate patent holders’ market share at scale across global e-commerce ecosystems.

The Verdict & Legal Analysis
Outcome
The case closed following plaintiff’s consolidation motion rather than a merits adjudication. No damages figure was disclosed, and no standalone injunctive relief ruling on the merits is reflected in the available case data. The basis of termination was not separately specified beyond the consolidation request.
Verdict Cause Analysis: The Consolidation Play
The plaintiff’s dispositive request asked the court to consolidate Case No. 1:25-cv-11201 with the pre-existing Schedule A action (Case No. 1:25-cv-05980). This is a strategically significant move for several reasons:
- Unified claim construction across all defendants, preventing inconsistent rulings on the same patent claims.
- Judicial economy, reducing duplicative motion practice on identical legal issues.
- Strategic leverage, as defendants face a coordinated enforcement front rather than isolated proceedings.
- Simplified injunctive relief, with a single court order potentially reaching all infringing sellers.
The fact that Zhongyi Jiang appeared as a plaintiff in the related Schedule A case (Case No. 1:25-cv-05980) while appearing as a defendant in the instant action creates an unusual procedural dynamic. This inversion may reflect a defensive patent assertion strategy by Jiang, or alternatively, a challenge to the Schedule A litigation mechanism itself. This dynamic warrants close attention from IP litigators tracking counter-assertion strategies in e-commerce patent disputes.
Legal Significance
This case illustrates the growing sophistication of Schedule A patent enforcement. Rather than litigating each defendant to judgment independently, plaintiff’s counsel at Aronberg Goldgehn pursued consolidation to efficiently manage what appears to be a multi-party enforcement campaign around U.S. Patent No. US12220071B1.
For patent practitioners, the case underscores that **venue selection and parallel case management** are as strategically important as claim construction in modern IP enforcement, particularly against distributed online sellers.
