The USPTO requires that applicants filing applications under Trademark Act §1 or §44 use the trademark electronic filing system. 37 C.F.R. §2.21(a); TMEP §§301.01, 301.01(a).

Before January 18, 2025, applicants had two electronic filing options of TEAS Standard and TEAS Plus, where the TEAS Plus filing option had a lower filing fee per class than TEAS Standard if the applicant met all TEAS Plus application requirements in the initial application.

On January 18, 2025, the USPTO replaced the TEAS Standard and TEAS Plus electronic filing options with a single base application where additional fees apply based on the complexity and completeness of the application. See TMEP §§819-819.04 regarding the base application requirements and additional fees.

In limited circumstances, an applicant may file a paper application at the highest per class filing fee set forth in 37 C.F.R. §2.6(a)(1)(i). See TMEP §301.01 regarding the limited exceptions when paper submissions may be permitted.

The current application filing fee amounts are available online at https://www.uspto.gov/trademark/trademark-fee-information.

Section 66(a) applications. Applications under §66(a) of the Trademark Act are sent to the USPTO electronically from the International Bureau of the World Intellectual Property Organization (IB).
