Filing Your Application Online
The Trademark Electronic Application System (TEAS) allows you to fill out an application form and check it for completeness, and then submit the application directly to the USPTO over the Internet. TEAS can be accessed at http://www.uspto.gov/trademarks/teas/index.jsp.
You must decide which version of the form to file, namely, either a TEAS Plus application or a "regular" TEAS application. The TEAS Plus form has a lower filing fee of $275 per class of goods and/or services, but has stricter requirements, than the "regular" TEAS form. A complete list of all the requirements is available at http://teasplus.uspto.gov/plushelp.html#Rule222(a). You must use the "regular" TEAS form, having a filing fee of $325 per class of goods and/or services, if you cannot satisfy the TEAS Plus requirements. Before accessing the electronic application form, you can preview the pages, to see what information will be required before starting the process.
You may also contact the Trademark Assistance Center at 1-800-786-9199 (1-571-272-9250) for a paper form. Paper forms are not processed as quickly as those submitted electronically, however.
