Introduction

In a case that underscores the growing complexity of multi-defendant e-commerce patent enforcement, AJ’s Nifty Products filed suit against more than 100 online marketplace sellers in the Northern District of Illinois, asserting infringement of U.S. Patent No. US11445840B1 — a patent directed to a drink caddy product design. The case, filed September 27, 2023, and closed March 7, 2024, concluded in just 162 days through voluntary dismissal with prejudice against the final named defendant, Wiueurtly, a Walmart marketplace seller.

This litigation represents a textbook example of the “Schedule A” mass-defendant patent enforcement strategy that has become a defining feature of IP litigation in the Northern District of Illinois. For patent attorneys, IP professionals, and R&D teams operating in the consumer products and accessories space, this case offers critical insights into how small product innovators assert patent rights against a fragmented, largely anonymous network of online sellers — and how such cases typically resolve before trial.

Case Overview

The Parties

The Patent at Issue

This case involved a utility patent covering a drink caddy apparatus, which underscores the active enforcement of IP in the competitive consumer goods market. Utility patents are registered with the U.S. Patent and Trademark Office (USPTO) and protect functional inventions.

• • US11445840B1 — Drink Caddy Apparatus (Application No. US17/016012)

Legal Representation

Plaintiff’s Counsel for AJ’s Nifty Products was **Bishop Diehl & Lee, Ltd.**, with attorneys **Benjamin Adam Campbell**, **Edward L. Bishop**, **Nicholas S. Lee**, and **Sameeul Haque**. No defense counsel appeared on record for any defendant.

Litigation Timeline & Procedural History

The case was filed in the Northern District of Illinois, a jurisdiction known for handling “Schedule A” patent enforcement actions, often characterized by efficient case management and early resolution. Presiding over the case was Chief Judge Jorge L. Alonso. The short duration of 162 days is typical for Schedule A proceedings that conclude through defaults, settlements, or voluntary dismissals rather than extensive trial proceedings.

No publicly available record of contested Markman hearings, summary judgment motions, or claim construction rulings was generated in this matter, consistent with the early-resolution pattern typical of this litigation model.

The Verdict & Legal Analysis

Outcome

The case concluded via voluntary dismissal with prejudice pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(i). The dismissal was filed by plaintiff’s counsel on March 14, 2024, and specifically named **Wiueurtly** (Walmart Seller ID: 101291859) as the final dismissed defendant. A dismissal “with prejudice” permanently extinguishes the plaintiff’s right to refile the same claims against this specific defendant. No damages amount or injunctive relief order was publicly disclosed.

Verdict Cause Analysis

The **basis of termination — voluntary dismissal** — does not reflect a judicial finding on the merits of infringement or patent validity. Instead, it suggests a common resolution in Schedule A litigation: a private settlement, the defendant’s marketplace removal of the accused product, or a strategic decision by the plaintiff that further pursuit was not economically justified.

Legal Significance

While this case does not establish binding precedent, it contributes to the broader data on **Schedule A patent enforcement practice** in the Northern District of Illinois. Rule 41(a)(1)(A)(i) dismissals filed before an answer or summary judgment motion require no court approval, offering plaintiffs flexibility. The absence of defense representation is noteworthy, highlighting ongoing due process discussions in mass-joinder Schedule A cases. Practitioners should monitor evolving local rules regarding Schedule A pleading standards.
