Patents and Trademarks

U.S. only coverage
USPTO's new trademark search system, which replaced the Trademark Electronic Search System (TESS) in November 2023.

Search the WIPO collections and trademarks collections of participating national and regional offices​​​​​​​.

Also known as the “Goods and Services Manual.” Search for acceptable identifications of goods and services with which a trademark may be associated.

The USPTO assigns each design mark one or more 6-digit design codes (similar to NAICS codes for industries). Each design code represents a type of figurative element. These codes allow you to search both broadly and narrowly.
