What happened: The dispute is before the Trademark Trial and Appeal Board and concerns federal protection for apparel. The baseball clubs argue their existing W marks have priority and that overlapping merchandise could confuse consumers.
Why it matters: A successful opposition could block the registration or force tighter limits on how the league uses the phrase on merchandise. The case tests how far established single-letter sports marks extend across apparel.
By the numbers: The WNBA application, serial No. 99105898, was filed March 26, 2025, and lists 15 apparel categories.
What to watch: Watch for a response, negotiated restrictions or a ruling from the trademark board.
