1004.02 Application May Be Based on More than One Foreign Registration
A U.S. application may be based on more than one foreign registration. The applicant must meet all requirements of the Trademark Act and rules for each foreign registration upon which the U.S. application is based, and must specify which goods/services are covered by which foreign registration.
If a §44 applicant amends an application to rely on a different foreign registration after publication, this is not considered a change in basis. However, if the amendment is acceptable, the application must be republished. See TMEP §1505.03(a) regarding post-publication amendments that require republication.
