Federal court filings
Schedule-A cases list defendants under a sealed exhibit and commonly seek ex parte temporary restraining orders under 15 U.S.C. §1116(d). When granted, the court order directs marketplaces (Etsy, Amazon, eBay) and payment processors (PayPal, Stripe) to restrain the listed defendants’ accounts pending the proceeding.
At the Trademark Trial and Appeal Board (TTAB)
Prevailed in 100% of proceedings the Board actually decided on the merits (settled and withdrawn proceedings excluded from this calculation).

Real trademark applications SANDISK CORPORATION challenged at the USPTO — the kind of design that draws an opposition. If your artwork looks like one of these, expect pushback. Each links to its USPTO docket.
