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 application filing option to use, namely, TEAS Plus, TEAS Reduced Fee (TEAS RF), or TEAS Regular. The TEAS Plus filing option has a filing fee of $225 per class of goods or services, but has the strictest requirements. A complete list of all the requirements is available at TMEP §819.01. If you cannot satisfy the TEAS Plus requirements, you must use the TEAS RF or TEAS Regular filing option. The TEAS Reduced Fee (TEAS RF) filing option is $275 per class of goods or services and requires the applicant to (1) provide an e-mail address and authorize the USPTO to send e-mail correspondence concerning the application throughout the application process and (2) agree to electronically file, through TEAS, certain application-related submissions that may be filed during the application process. The TEAS Regular filing option is $400 per class, but does not have the additional requirements of TEAS Plus or TEAS RF. If you file a TEAS Plus or TEAS RF application but do not satisfy the relevant requirements you will be required to submit an additional processing fee of $125 per class of goods or services, and the application will then be handled as a TEAS Regular application. Before accessing the electronic application form, you can preview the pages, to see what information will be required before starting the process.
