Sonic the Hedgehog Trademark Infringement Lawsuit: Sega Schedule A Case No. 1:26-cv-11854
Sega Corporation and Sega of America, Inc. File a Federal Trademark Lawsuit on September 28, 2026, in the Northern District of Illinois – Sonic the Hedgehog Brand Claims, Defendant Joinder Issues, and Docket Updates
Sega Corporation and Sega of America, Inc. filed a federal trademark infringement lawsuit on September 28, 2026, in the U.S. District Court for the Northern District of Illinois. The lawsuit reportedly concerns alleged infringement of trademark rights associated with Sonic the Hedgehog, the internationally recognized video game franchise developed and published by Sega.
The lawsuit was filed against defendants identified through Schedule A, a format commonly used in intellectual property enforcement actions involving multiple online sellers and e-commerce businesses.
Court records subsequently show that the judge questioned whether the plaintiff companies had adequately established grounds for joining 75 defendants in a single lawsuit.
The specific trademarks, accused merchandise, and alleged infringing activities involved in this action should be confirmed through the complaint and supporting exhibits.
Case Information
Plaintiffs: Sega Corporation and Sega of America, Inc.
Defendants: The Partnerships and Unincorporated Associations Identified on Schedule A
Court: U.S. District Court for the Northern District of Illinois
Case No.: 1:26-cv-11854
Date Filed: September 28, 2026
Presiding Judge: Hon. Sunil R. Harjani
Nature of Action: Trademark Infringement – 15 U.S.C. § 1114 (Lanham Act)
Reported Brand at Issue: Sonic the Hedgehog (subject to confirmation)
Case Update: On September 28, 2026, Sega Corporation and Sega of America, Inc. filed their trademark infringement complaint with five supporting exhibits. The plaintiffs also submitted Schedule A and an additional multipart exhibit under seal, requested permission to file certain documents under seal, and filed a Notice of Claims Involving Trademarks.
On September 30, 2026, Judge Sunil R. Harjani entered a minute order raising concerns about whether the 75 defendants were properly joined in one action. The court directed the plaintiffs to file a supplemental memorandum addressing joinder by October 6, 2026. Alternatively, the plaintiffs were permitted to amend the complaint to identify a single defendant or a smaller group of defendants and explain why their inclusion in the same proceeding was appropriate.
The available public records do not establish whether the plaintiffs complied with that deadline or how the court subsequently resolved the joinder issue.
