Priority Right - Types of Priority Rights - Priority Rights Under Other Multilateral Arrangements - Patent Cooperation Treaty

Patent Cooperation Treaty

The Patent Cooperation Treaty, in its Article 8(1), provides the possibility of claiming a right of priority for the filing of an international application (PCT application):

The international application may contain a declaration, as prescribed in the Regulations, claiming the priority of one or more earlier applications filed in or for any country party to the Paris Convention for the Protection of Industrial Property.

Rule 4.10(a) PCT goes on to mention that:

Any declaration referred to in Article 8(1) ("priority claim") may claim the priority of one or more earlier applications filed either in or for any country party to the Paris Convention for the Protection of Industrial Property or in or for any Member of the World Trade Organization that is not party to that Convention.

However, Rule 4.10(a) as amended with effect from January 1, 2000 does not apply to all designated Offices. For instance, for the European Patent Office as designated Office, the old Rule 4.10(a) still applied until December 12, 2007, that is, rights of priority of first applications made in a WTO member not party to the Paris Convention were not recognised. Now and more specifically for European patent applications filed on or after December 13, 2007 (the entry into force of the new version of the European Patent Convention, the so-called EPC 2000), the rights of priority of first applications made in a WTO member are recognized under the European Patent Convention.

Famous quotes containing the words patent, cooperation and/or treaty:

    There is a patent office at the seat of government of the universe, whose managers are as much interested in the dispersion of seeds as anybody at Washington can be, and their operations are infinitely more extensive and regular.
    Henry David Thoreau (1817–1862)

    Psychoanalysis is an attempt to examine a person’s self-justifications. Hence it can be undertaken only with the patient’s cooperation and can succeed only when the patient has something to gain by abandoning or modifying his system of self-justification.
    Thomas Szasz (b. 1920)

    He was then in his fifty-fourth year, when even in the case of poets reason and passion begin to discuss a peace treaty and usually conclude it not very long afterwards.
    —G.C. (Georg Christoph)
