An applicant must file a claim of priority within six months

after

the filing date of the foreign application.

15 U.S.C.

§1126(d)(1)

;

37 C.F.R.

§§2.34(a)(4)(i)

,

2.35(b)(5)

; Paris Convention Article 4(C)(3). The applicant can submit

the priority claim after the filing date of the U.S. application, as long as the claim of

priority is submitted within six months of the foreign filing and the claimed priority date

is earlier than the filing date of the U.S. application.

Example:

If an eligible applicant files in France on December 6, 2011,

and in the United States on January 12, 2012, the applicant can add a priority claim to

the United States application on or before June 6, 2012, if the applicant meets the

requirements of §44(d). The applicant cannot add a priority claim to the U.S. application

after June 6, 2012.

If an applicant claims priority under §44(d), but does not

specify the filing date of the foreign application, the examining attorney must require that

the applicant specify the date of the foreign filing.

If the applicant submits a claim of priority more than six

months after the date of the foreign filing, the examining attorney must advise the

applicant that it is not entitled to priority.
