Priority Right for Foreign Applications
Note:
The right to rely on a foreign application as the basis for filing in the U.S. is known as the right of priority under international patent law.

The right to rely on a foreign application is known as the right of priority in international patent law and this phrase has been adopted in the U.S. statute. The right of priority originated in a multilateral treaty of 1883, to which the United States adhered in 1887, known as the Paris Convention for the Protection of Industrial Property (Paris Convention). The treaty is administered by the World Intellectual Property Organization (WIPO) at Geneva, Switzerland. This treaty has been revised several times, the latest revision in effect being written in Stockholm in July 1967 (copy at Appendix P of this Manual). Articles 13-30 of the Stockholm Revision became effective on September 5, 1970. Articles 1-12 of the Stockholm Revision became effective on August 25, 1973. One of the many provisions of the Paris Convention requires each of the adhering countries to accord the right of priority to the nationals of the other countries and the first United States statute relating to this subject was enacted to carry out this obligation. A foreign country may also provide for this right by reciprocal legislation.

Right of Priority for Industrial Property Applications
Note:
Allows a patent application to claim priority based on an earlier filing in another country adhering to the Paris Convention.

Under Article 4A of the Paris Convention for the Protection of Industrial Property, a right of priority may be based on an application for a patent or for the registration of a utility model or an industrial design filed under the national law of a foreign country adhering to the Convention, or on a foreign application filed under a bilateral or multilateral treaty concluded between two or more such countries. Examples of such treaties pertaining to the protection of designs are The Hague Agreement Concerning the International Registration of Industrial Designs, the Benelux Designs Convention, and the Office for Harmonization in the Internal Market (OHIM) as created under European Union law. Treaties pertaining to utility and/or plant patents include The Convention on the Grant of European Patents (which established the European Patent Office), the Patent Cooperation Treaty, and the International Convention for the Protection of New Varieties of Plants (UPOV).
