Article 307.
A minimum of one year after the coming into force of the present Treaty shall be accorded to the nationals of the High Contracting Parties, without extension fees or other penalty, in order to enable such persons to accomplish any act, fulfil any formality, pay any fees, and generally satisfy any obligation prescribed by the laws or regulations of the respective States relating to the obtaining, preserving, or opposing rights to, or in respect of, industrial property either acquired before August 1, 1914, or which, except for the war, might have been acquired since that date as a result of an application made before the war or during its continuance, but nothing in this Article shall give any right to reopen interference proceedings in the United States of America where a final hearing has taken place.
All rights in, or in respect of, such property which may have lapsed by reason of any failure to accomplish any act, fulfil any formality, or make any payment, shall revive, but subject in the case of patents and designs to the imposition of such conditions as each Allied or Associated Power may deem reasonably necessary for the protection of persons who have manufactured or made use of the subject matter of such property while the rights had lapsed. Further, where rights to patents or designs belonging to German nationals are revived under this Article, they shall be subject in respect of the grant of licenses to the same provisions as would have been applicable to them during the war, as well as to all the provisions of the present Treaty.
The period from August 1, 1914, until the coming into force of the present Treaty shall be excluded in considering the time within which a patent should be worked or a trade mark or design used, and it is further agreed that no patent, registered trade mark or design in force on August 1, 1914, shall be subject to revocation or cancellation by reason only of the failure to work such patent or use such trade-mark or design for two years after the coming into force of the present Treaty.
Article 308.
The rights of priority, provided by Article 4 of the International Convention for the Protection of Industrial Property of Paris, of March 20, 1883, revised at Washington in 1911 or by any other Convention or Statute, for the filing or registration of applications for patents or models of utility, and for the registration of trade marks, designs and models which had not expired on August 1, 1914, and those which have arisen during the war, or would have arisen but for the war, shall be extended by each of the High Contracting Parties in favour of all nationals of the other High Contracting Parties for a period of six months after the coming into force of the present Treaty.
Nevertheless, such extension shall in no way affect the right of any of the High Contracting Parties or of any person who before the coming into force of the present Treaty was bonâ fide in possession of any rights of industrial property conflicting with rights applied for by another who claims rights of priority in respect of them, to exercise such rights by itself or himself personally, or by such agents or licensees as derived their rights from it or him before the coming into force of the present Treaty; and such persons shall not be amenable to any action or other process of law in respect of infringement.
Article 309.
No action shall be brought and no claim made by persons residing or carrying on business within the territories of Germany on the one part and of the Allied or Associated Powers on the other, or persons who are nationals of such Powers respectively, or by any one deriving title during the war from such persons, by reason of any action which has taken place within the territory of the other party between the date of the declaration of war and that of the coming into force of the present
