Article 168 Territorial field of application

Any Contracting State may declare in its instrument of ratification or accession, or may inform the Government of the Federal Republic of Germany by written notification at any time thereafter, that this Convention shall be applicable to one or more of the territories for the external relations of which it is responsible. European patents granted for that Contracting State shall also have effect in the territories for which such a declaration has taken effect.

If the declaration referred to in paragraph 1 is contained in the instrument of ratification or accession, it shall take effect on the same date as the ratification or accession; if the declaration is notified after the deposit of the instrument of ratification or accession, such notification shall take effect six months after the date of its receipt by the Government of the Federal Republic of Germany.

Any Contracting State may at any time declare that the Convention shall cease to apply to some or to all of the territories in respect of which it has given notification pursuant to paragraph 1. Such declaration shall take effect one year after the date on which the Government of the Federal Republic of Germany received notification thereof.
