26-cv-13003 | ABG-Champion LLC Files Schedule A Case: Champion Sportswear-Related Sellers Should Check

Case overview

• Plaintiff: ABG-Champion LLC
• Court: U.S. District Court for the Northern District of Illinois
• Filed: October 22, 2026 (per CourtListener)
• Status: Filed. The docket shows a sealed document (Seal) filed the same day.

About the plaintiff: The “ABG” and “Champion” in the plaintiff’s name are consistent with public reports that Authentic Brands Group (ABG) acquired the Champion sportswear brand (source below). We have not found a public source directly describing ABG-Champion LLC’s relationship to the Champion brand; the complaint will be the authority.

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 the Champion brand, this case may be the source.

Seller checklist

• Check for hoodies, T-shirts, sportswear, caps, and bags bearing “Champion” or its “C” logo
• Check whether titles or keywords use the Champion name to attract traffic
• 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.
