Section 44(d) of the Trademark Act,

15 U.S.C.

§1126(d)

, provides for a priority filing date to eligible applicants

(

see

TMEP §1002.02

) who have

filed an application in a treaty country as defined by §44(b) (

see

TMEP §1002.03

). If an

eligible applicant files the U.S. application claiming §44(d) priority within six months of

filing the first application to register the mark in a treaty country, the filing date of the

first-filed foreign application is the effective filing date of the U.S. application.

The requirements for receipt of a priority filing date under

§44(d) for a trademark or service mark application are:

(1) The eligible applicant must file a claim of priority within

six months of the filing date of the first-filed foreign application.

based upon a subsequent regularly filed application in the same foreign country, and that

any prior-filed application has been withdrawn, abandoned, or otherwise disposed of,

without having been laid open to public inspection and without having any rights

outstanding, and has not served as a basis for claiming a right of

priority.

or agreement with the United States that provides a right of priority, or must extend

reciprocal rights to priority to U.S. nationals.
