U.S. Trademark Searching

Trademark Searching can be complicated due to the different parts involved.

Trademark usually consists of three distinct parts:

  1. Name or Wordmark
  2. Logo, Picture or Design
  3. Class of Goods and Services

A Trademark search usually consists of searching these three parts individually and then putting them together.


1.  Searching the Name or Wordmark

I suggest using the Basic Word Mark Search option

Search the Trademark Electronic Search System (TESS)

2.  Searching for the Logo, Picture or Design

Browse and search the Design Search Code Manual


3.  Searching the Class of Goods and Services

Bascially each type of goods or service has a class code and you are searching for this code.

And of course you will also want to search the internet for such trademarks to see if the word, logo, or design has been used in commerce previously.
