Supreme Court to Review Trademark Strength Determination

The U.S. Supreme Court agreed on July 7, 2026, to hear arguments on the proper role of courts in evaluating trademark strength. The case stems from a dispute involving RiseandShine Corporation and centers on whether certain factors in strength analysis require judicial determination as a matter of law.

The petition follows a Ninth Circuit decision and raises questions about consistency in how federal courts weigh evidence of trademark distinctiveness and commercial strength during infringement claims. The matter is expected to be argued in the October 2026 term.

Trademark practitioners note that the outcome could affect litigation strategies in cases where parties dispute the scope of protection afforded to marks based on acquired distinctiveness.
