If a mark has already been registered in a foreign country (or an application has been filed in a foreign country), then use in the United States is not a requirement of registration on the Supplemental Register, as long as the U.S. application for registration is filed within six months of the foreign filing. However, use of the mark in the United States is required in order to receive the benefits of registration on the Principal Register. Foreign applicants who rely on their foreign application as a basis for registration on the Supplemental Register do not need specimens, nor do they need to provide the dates of first use nor specify the manner of affixing the mark to the goods. However, such applicants must specify their priority date in the heading of the application. Also, all foreign applicants must provide the name of a domestic representative on whom notices of process can be served regarding the application.
