26-cv-12969 | Supreme Affiliate Chapter 4 Corp. Files Again: Streetwear Sellers Should Check

Case overview

• Plaintiff: Chapter 4 Corp. (per The Fashion Law, the corporate entity associated with the Supreme streetwear brand)
• Court: U.S. District Court for the Northern District of Illinois, Judge John Robert Blakey
• Filed: October 21, 2026
• Status: Filed. The plaintiff also filed a “Leave to File” procedural document the same day, which in Schedule A cases is typically used to seek leave to file the defendant list and other materials under seal.

Chapter 4 Corp. has filed Schedule A cases in the Northern District of Illinois before, e.g. 1:25-cv-13822 and 1:25-cv-14021 in 2025 (sources below).

The complaint and Schedule A defendant list are not yet public; the rights and products at issue will be updated.

What may happen next

Schedule A plaintiffs usually move for a TRO within days of filing. Once granted, marketplaces freeze defendants’ funds. If your store is frozen in the coming days and your products relate to this brand, this case is a likely source.

Seller checklist

• Check for apparel, caps, backpacks, phone cases, and stickers bearing “Supreme” or its red box logo
• “Collab” or “same style” descriptions carry the same risk if they use the brand’s marks without a license
• Check whether listing images reuse the brand’s official photography

Already frozen?

Keep the platform notice, emails from plaintiff’s counsel, affected listings, and sales records. Hold off on replying to the plaintiff or signing anything, and have counsel review the case. See: Store Frozen by a TRO: The First 72 Hours.
