This page contains information on the use of the PTO Web Trademark Database Number Search Page.

The Number Search page allows you to search by registration number (for registered marks) or by serial number (for pending marks). While you can search for document numbers in other ways, this page is designed to simplify one of the most common types of searching as much as possible. To use the page:

1. Type the number or numbers (separated by spaces) you're interested in into the box. If you include more than one number, they should be separated by a space. Your search will work fine, whether you include commas or not.
2. Hit the Search button.

The database will be searched for all the numbers you provide, and a list of the ones found will be returned, sorted with the most recent ones first. Both the Serial Number and Registration number fields will be searched for the numbers you specify.

A few things to note:

• Anything you enter into the number search box that is not a recognizable number (other terms, operators like 'OR' or 'AND') will be ignored. The search will be conducted only on any entries you make that are recognized as numbers. See Help on Field Searching for information on how to enter Serial Numbers and Registration Numbers.
• The 'Refine Search' box on the search results page will use the same query format as the Manual Search page. See the Manual Search Help page for details on its use.
