Declaration of Incontestability of a Mark under Section 15
(15 U.S.C. § 1065)

TEAS - Version 5.10: 07/15/2017
To claim that a mark registered on the Principal Register is now incontestable, you must file a Section 15 declaration once the mark has been in continuous use in commerce for a period of five (5) years after the date of registration, or date of publication under § 12(c), and the mark is still in use in commerce. (Section 15 does NOT apply to marks on the Supplemental Register). You may file this declaration within one (1) year after the expiration of either any five-year period of continuous use following registration, or any five-year period of continuous use after publication under § 12(c).

NOTE: You must complete any field preceded by the symbol "*".

WARNING: This form has a session time limit of 60 minutes. Your "session" began as soon as you accessed this initial Form Wizard page. If you exceed the 60-minute time limit, the form will not validate and you must begin the entire process again; you can, however, extend the time limit. You should always try to have all information required to complete the form prior to starting any session.

:    (required only if completing the form for the first time)
WARNING: Be sure you are entering a registration number and NOT a serial number.

WARNING: You are filing a Section 15 declaration of incontestability. If a Section 8 affidavit of use or a combined Section 8 affidavit of use/Section 9 renewal application is also due, it is not included here. If necessary, please see the Declaration of Use of a Mark under Section 8 or Combined declaration of use in commerce/application for renewal of registration of mark under Sections 8 & 9. If a Section 8 or combined Section 8 & 9 is due and is not timely filed, your registration will be cancelled. Please make sure you file all the required forms, and that the owner/holder name identified on the form(s) is correct.
