What Is a U.S. Trademark?
A trademark is any word, logo, slogan, or design that identifies the source of goods or services. Federal registration with the USPTO gives you nationwide priority and the right to sue infringers in federal court.
Search Before You Launch
A clearance search through the USPTO TESS database is the single most important step before naming a product or brand. Conflict with an existing registered mark can cost six figures in rebranding.
How to search →File the Right Application
Use-in-commerce (1a) or Intent-to-Use (1b) — picking the wrong basis is the most common reason applications fail. As of 2026 the USPTO charges a $350 base fee per class, plus surcharges for custom identifications.
Filing guide →Protect & Maintain
Registration lasts 10 years but requires renewal declarations at year 5–6 (Section 8) and every 10 years (Section 9). Failure to file = cancellation. Abandoned marks are lost permanently.
