Universele Auteursrecht-Conventie, zoals herzien te Parijs op 24 juli 1971

Each Contracting State undertakes to provide for the adequate and effective protection of the rights of authors and other copyright proprietors in literary, scientific and artistic works, including writings, musical, dramatic and cinematographic works, and paintings, engravings and sculpture.

1. Published works of nationals of any Contracting State and works first published in that State shall enjoy in each other Contracting State the same protection as that other State accords to works of its nationals first published in its own territory, as well as the protection specially granted by this Convention.
2. Unpublished works of nationals of each Contracting State shall enjoy in each other Contracting State the same protection as that other State accords to unpublished works of its own nationals, as well as the protection specially granted by this Convention.
3. For the purpose of this Convention any Contracting State may, by domestic legislation, assimilate to its own nationals any person domiciled in that State.

1. Any Contracting State which, under its domestic law, requires as a condition of copyright, compliance with formalities such as deposit, registration, notice, notarial certificates, payment of fees or manufacture or publication in that Contracting State, shall regard these requirements as satisfied with respect to all works protected in accordance with this Convention and first published outside its territory and the author of which is not one of its nationals, if from the time of the first publication all the copies of the work published with the authority of the author or other copyright proprietor bear the symbol © accompanied by the name of the copyright proprietor and the year of first publication placed in such manner and location as to give reasonable notice of claim of copyright.
2. The provisions of paragraph 1 shall not preclude any Contracting State from requiring formalities or other conditions for the acquisition and enjoyment of copyright in respect of works first published in its territory or works of its nationals wherever published.
3. The provisions of paragraph 1 shall not preclude any Contracting State from providing that a person seeking judicial relief must, in bringing the action, comply with procedural requirements, such as that the complainant must appear through domestic counsel or that the complainant must deposit with the court or an administrative office, or both, a copy of the work involved in the litigation; provided that failure to comply with such requirements shall not affect the validity of the copyright, nor shall any such requirement be imposed upon a national of another Contracting State if such requirement is not imposed on nationals of the State in which protection is claimed.
4. In each Contracting State there shall be legal means of protecting without formalities the unpublished works of nationals of other Contracting States.
5. If a Contracting State grants protection for more than one term of copyright and the first term is for a period longer than one of the minimum periods prescribed in Article IV, such State shall not be required to comply with the provisions of paragraph 1 of this Article in respect of the second or any subsequent term of copyright.

1. The duration of protection of a work shall be governed, in accordance with the provisions of Article II and this Article, by the law of the Contracting State in which protection is claimed.
2. (a) The term of protection for works protected under this Convention shall not be less than the life of the author and twentyfive years after his death. However, any Contracting State which, on the effective date of this Convention in that State, has limited this term for certain classes of works to a period computed from the first publication of the work, shall be entitled to maintain these exceptions and to extend them to other classes of works. For all these classes the term of protection shall not be less than twenty-five years from the date of first publication.
(b) Any Contracting State which, upon the effective date of this Convention in that State, does not compute the term of protection upon the basis of the life of the author, shall be entitled to compute the term of protection from the date of the first publication of the work or from its registration prior to publication, as the case may be, provided the term of protection shall not be less than twenty-five years from the date of first publication or from its registration prior to publication, as the case may be.
(c) If the legislation of a Contracting State grants two or more successive terms of protection, the duration of the first term shall not be less than one of the minimum periods specified in sub-paragraphs (a) and (b).
3. The provisions of paragraph 2 shall not apply to photographic works or to works of applied art; provided, however, that the term of protection in those Contracting States which protect photographic works, or works of applied art in so far as they are protected as artistic works, shall not be less than ten years for each of said classes of works.
4. (a) No Contracting State shall be obliged to grant protection work for a period longer than that fixed for the class of works to which the work in question belongs, in the case of unpublished works by the law of the Contracting State of which the author is a national, and in the case of published works by the law of the Concting State in which the work has been first published.
(b) For the purposes of the application of sub-paragraph (a), if the law of any Contracting State grants two or more successive terms of protection, the period of protection of that State shall be considered to be the aggregate of those terms. However, if a specified work is not protected by such State during the second or any subsequent term for any reason, the other Contracting States shall not be obliged to protect it during the second or any subsequent term.
5. For the purposes of the application of paragraph 4, the work of a national of a Contracting State, first published in a non-Contracting State, shall be treated as though first published in the Contracting State of which the author is a national.
6. For the purposes of the application of paragraph 4, in case of simultaneous publication in two or more Contracting States, the work shall be treated as though first published in the State which affords the shortest term; any work published in two or more Contracting States within thirty days of its first publication shall be considered as having been published simultaneously in said Contracting States.

1. The rights referred to in Article I shall include the basic rights ensuring the author's economic interests, including the exclusive right to authorize reproduction by any means, public performance and broadcasting. The provisions of this Article shall extend to works protected under this Convention either in their original form or in any form recognizably derived from the original.
2. However, any Contracting State may, by its domestic legislation, make exceptions that do not conflict with the spirit and provisions of this Convention, to the rights mentioned in paragraph 1 of this Article. Any State whose legislation so provides, shall nevertheless accord a reasonable degree of effective protection to each of the rights to which exception has been made.

1. This Convention shall come into force three months after the deposit of twelve instruments of ratification, acceptance or accession.
2. Subsequently, this Convention shall come into force in respect of each State three months after that State has deposited its instrument of ratification, acceptance or accession.
3. Accession of this Convention by a State not party to the 1952 Convention shall also constitute accession to that Convention; however, if its instrument of accession is deposited before this Convention comes into force, such State may make its accession to the 1952 Convention conditional upon the coming into force of this Convention. After the coming into force of this Convention, no State may accede solely to the 1952 Convention.
4. Relations between States party to this Convention and States that are party only to the 1952 Convention, shall be governed by the 1952 Convention. However, any State party only to the 1952 Convention may, by a notification deposited with the Director-General, declare that it will admit the application of the 1971 Convention to works of its nationals or works first published in its territory by all States party to this Convention.

1. The rights referred to in Article I shall include the exclusive right of the author to make, publish and authorize the making and publication of translations of works protected under this Convention.
2. However, any Contracting State may, by its domestic legislation, restrict the right of translation of writings, but only subject to the following provisions:
(a) If, after the expiration of a period of seven years from the date of the first publication of a writing, a translation of such writing has not been published in a language in general use in the Contracting State, by the owner of the right of translation or with his authorization, any national of such Contracting State may obtain a non-exclusive licence from the competent authority thereof to translate the work into that language and publish the work so translated.
(b) Such national shall in accordance with the procedure of the State concerned, establish either that he has requested, and been denied, authorization by the proprietor of the right to make and publish the translation, or that, after due diligence on his part, he was unable to find the owner of the right. A licence may also be granted on the same conditions if all previous editions of a translation in a language in general use in the Contracting State are out of print.
(c) If the owner of the right of translation cannot be found, then the applicant for a licence shall send copies of his application to the publisher whose name appears on the work and, if the nationality of the owner of the right of translation is known, to the diplomatic or consular representative of the State of which such owner is a national, or to the organization which may have been designated by the government of that State. The licence shall not be granted before the expiration of a period of two months from the date of the dispatch of the copies of the application.
(d) Due provision shall be made by domestic legislation to ensure to the owner of the right of translation a compensation which is just and conforms to international standards, to ensure payment and transmittal of such compensation, and to ensure a correct translation of the work.
(e) The original title and the name of the author of the work shall be printed on all copies of the published translation. The licence shall be valid only for publication of the translation in the territory of the Contracting State where it has been applied for. Copies so published may be imported and sold in another Contracting State if a language in general use in such other State is the same language as that into which the work has been so translated, and if the domestic law in such other State makes provision for such licences and does not prohibit such importation and sale. Where the foregoing conditions do not exist, the importation and sale of such copies in a Contracting State shall be governed by its domestic law and its agreements. The licence shall not be transferred by the licensee.
(f) The licence shall not be granted when the author has withdrawn from circulation all copies of the work.

“Publication”, as used in this Convention, means the reproduction in tangible form and the general distribution to the public of copies of a work from which it can be read or otherwise visually perceived.

This Convention shall not apply to works or rights in works which, at the effective date of this Convention in a Contracting State where protection is claimed, are permanently in the public domain in the said Contracting State.

1. This Convention, which shall bear the date of 24 July 1971, shall be deposited with the Director-General and shall remain open for signature by all States party to the 1952 Convention for a period of 120 days after the date of this Convention. It shall be subject to ratification or acceptance by the signatory States.
2. Any State which has not signed this Convention may accede thereto.
3. Ratification, acceptance or accession shall be effected by the deposit of an instrument to that effect with the Director-General.

1. Any Contracting State regarded as a developing country in conformity with the established practice of the General Assembly of the United Nations may, by a notification deposited with the Director-General of the United Nations Educational, Scientific and Cultural Organization (hereinafter called “the Director-General”) at the time of its ratification, acceptance or accession or thereafter, avail itself of any or all of the exceptions provided for in Articles Vter and Vquater.
2. Any such notification shall be effective for ten years from the date of coming into force of this Convention, or for such part of that ten-year period as remains at the date of deposit of the notification, and may be renewed in whole or in part for further periods of ten years each if, not more than fifteen or less than three months before the expiration of the relevant ten-year period, the Contracting State deposits a further notification with the Director-General. Initial notifications may also be made during these further periods of ten years in accordance with the provisions of this Article.
3. Notwithstanding the provisions of paragraph 2, a Contracting State that has ceased to be regarded as a developing country as referred to in paragraph 1 shall no longer be entitled to renew its notification made under the provisions of paragraph 1 or 2, and whether or not it formally withdraws the notification such State shall be precluded from availing itself of the exceptions provided for in Articles Vter and Vquater at the end of the current ten-year period, or at the end of three years after it has ceased to be regarded as a developing country, whichever period expires later.
4. Any copies of a work already made under the exceptions provided for in Articles Vter and Vquater may continue to be distributed after the expiration of the period for which notifications under this Article were effective until their stock is exhausted.
5. Any Contracting State that has deposited a notification in accordance with Article XIII with respect to the application of this Convention to a particular country or territory, the situation of which can be regarded as analogous to that of the States referred to in paragraph 1 of this Article, may also deposit notifications and renew them in accordance with the provisions of this Article with respect to any such country or territory. During the effective period of such notifications, the provisions of Articles Vter and Vquater may be applied with respect to such country or territory. The sending of copies from the country or territory to the Contracting State shall be considered as export within the meaning of Articles Vter and Vquater.

1. Any Contracting State to which Article Vbis (1) applies may adopt the following provisions:
(a) If, after the expiration of (i) the relevant period specified in sub-paragraph (c) commencing from the date of first publication of particular edition of a literary, scientific or artistic work referred to paragraph 3, or (ii) any longer period determined by national legislation of the State, copies of such edition have not been distributed in that State to the general public or in connexion with systematic instructional activities at a price reasonably related to that normally charged in the State for comparable works, by the owner of the right of reproduction or with his authorization, any national of such State may obtain a non-exclusive licence from the competent authority to publish such edition at that or a lower price for use in connexion with systematic instructional activities. The licence may only be granted if such national, in accordance with the procedure of the State concerned, establishes either that he has requested, and been denied, authorization by the proprietor of the right to publish such work, or that, after due diligence on his part, he was unable to find the owner of the right. At the same time as he makes his request he shall inform either the international copyright information centre established by the United Nations Educational, Scientific and Cultural Organization or any national or regional information centre referred to in subparagraph (d).
(b) A licence may also be granted on the same conditions if, for a period of six months, no authorized copies of the edition in question have been on sale in the State concerned to the general public or in connexion with systematic instructional activities at a price reasonably related to that normally charged in the State for comparable works.
