301.02(a) Treaty-exempt Filers under International Agreements
The United States is a member of both the Trademark Law Treaty (TLT) and the subsequent Singapore Treaty on the Law of Trademarks (STLT), which constitute two separate international instruments that may be ratified or acceded to independently by member countries. Nationals of TLT members that are not also members of STLT at the time of submission of the relevant document to the USPTO are not required to file trademark submissions electronically, receive communications from the USPTO via email, or submit a petition to accept a paper filing. See 37 C.F.R. §§2.21(c), 2.23(c), 7.4(c).
