Nevertheless, all acts done by virtue of the special measures taken during the war under legislative, executive or administrative authority of any Allied or Associated Power in regard to the rights of German nationals in industrial, literary or artistic property shall remain in force and shall continue to maintain their full effect.

No claim shall be made or action brought by Germany or German nationals in respect of the use during the war by the Government of any Allied or Associated Power, or by any persons acting on behalf or with the assent of such Government of any rights in industrial, literary or artistic property, nor in respect of the sale, offering for sale, or use of any products, articles, or apparatus whatsoever to which such rights applied.

Unless the legislation of any one of the Allied or Associated Powers in force at the moment of the signature of the present treaty otherwise directs, sums due or paid in virtue of any act or operation resulting from the execution of the special measures mentioned in Paragraph 1 of this article shall be dealt with in the same way as other sums due to German nationals are directed to be dealt with by the present treaty; and sums produced by any special measures taken by the German Government in respect of rights in industrial, literary or artistic property belonging to the nationals of the Allied or Associated Powers shall be considered and treated in the same way as other debts due from German nationals.

Each of the Allied and Associated Powers reserves to itself the right to impose such limitations, conditions or restrictions on rights of industrial, literary or artistic property (with the exception of trade-marks) acquired before or during the war, or which may be subsequently acquired in accordance with its legislation, by German nationals, whether by granting licenses, or by the working, or by preserving control over their exploitation, or in any other way as may be considered necessary for national defense or in the public interest, or for assuring the fair treatment by Germany of the rights of industrial, literary, and artistic property held in German territory by its nationals, or for securing the due fulfillment of all the obligations undertaken by Germany in the present treaty.

As regards rights of industrial, literary and artistic property acquired after the coming into force of the present treaty, the right so reserved by the Allied and Associated Powers shall only be exercised in cases where these limitations, conditions or restrictions may be considered necessary for national defense or in the public interest.

In the event of the application of the provisions of the preceding paragraph by any of the Allied or Associated Powers, there shall be paid reasonable indemnities or royalties which shall be dealt with in the same way as other sums due to German nationals are directed to be dealt with by the present treaty.

Each of the Allied or Associated Powers reserves the right to treat as void and of no effect any transfer in whole or in part of or other dealing with rights of or in respect of industrial, literary or artistic property effected after Aug. 1, 1914, or in the future, which would have the result of defeating the objects of the provisions of this article.

The provisions of this article shall not apply to rights in industrial, literary or artistic property which have been dealt with in the liquidation of businesses or companies under war legislation by the Allied or Associated Powers, or which may be so dealt with by virtue of Article 297, Paragraph (b).

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, fulfill 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 the 1st of August, 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, fulfill 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.
