European Treaty Series - No. 47
Convention on the Unification of Certain Points of Substantive Law on Patents for Invention
The member States of the Council of Europe, signatory hereto,
Considering that the aim of the Council of Europe is to achieve a greater unity between its members for the purpose, among others, of facilitating their economic and social progress by agreements and common action in economic, social, cultural, scientific, legal and administrative matters;
Considering that the unification of certain points of substantive law on patents for invention is likely to assist industry and inventors, to promote technical progress and contribute to the creation of an international patent;
Having regard to Article 15 of the Convention for the Protection of Industrial Property signed at Paris on 20th March 1883, revised at Brussels on 14th December 1900, at Washington on 2nd June 1911, at The Hague on 6th November 1925, at London on 2nd June 1934 and at Lisbon on 31st October 1958,
Have agreed as follows:
In the Contracting States, patents shall be granted for any inventions which are susceptible of industrial application, which are new and which involve an inventive step. An invention which does not comply with these conditions shall not be the subject of a valid patent. A patent declared invalid because the invention does not comply with these conditions shall be considered invalid ab initio.
The Contracting States shall not be bound to provide for the grant of patents in respect of:
ainventions the publication or exploitation of which would be contrary to ordre public or morality, provided that the exploitation shall not be deemed to be so contrary merely because it is prohibited by a law or regulation;
bplant or animal varieties or essentially biological processes for the production of plants or animals; this provision does not apply to micro-biological processes and the products thereof.
An invention shall be considered as susceptible of industrial application if it can be made or used in any kind of industry including agriculture.
1An invention shall be considered to be new if it does not form part of the state of the art.
2Subject to the provisions of paragraph 4 of this article, the state of the art shall be held to comprise everything made available to the public by means of a written or oral description, by use, or in any other way, before the date of the patent application or of a foreign application, the priority of which is validly claimed.
3Any Contracting State may consider the contents of applications for patents made, or of patents granted, in that State, which have been officially published on or after the date referred to in paragraph 2 of this article, as comprised in the state of the art, to the extent to which such contents have an earlier priority date.
4A patent shall not be refused or held invalid by virtue only of the fact that the invention was made public, within six months preceding the filing of the application, if the disclosure was due to, or in consequence of:
aan evident abuse in relation to the applicant or his legal predecessor, or
bthe fact that the applicant or his legal predecessor has displayed the invention at official, or officially recognised, international exhibitions falling within the terms of the Convention on international exhibitions signed at Paris on 22nd November 1928 and amended on 10th May 1948.
An invention shall be considered as involving an inventive step if it is not obvious having regard to the state of the art. However, for the purposes of considering whether or not an invention involves an inventive step, the law of any Contracting State may, either generally or in relation to particular classes of patents or patent applications, for example patents of addition, provide that the state of the art shall not include all or any of the patents or patent applications mentioned in paragraph 3 of Article 4.
Any Contracting State which does not apply the provisions of paragraph 3 of Article 4 shall nevertheless provide that no invention shall be validly protected in so far as it includes matter which is or has been validly protected by a patent in that State which, though not comprised in the state of the art, has, in respect of that matter, an earlier priority date.
Any group of Contracting States who provide for a common patent application may be regarded as a single State for the purposes of paragraph 3 of Article 4, or of Article 6.
1The patent application shall contain a description of the invention with the necessary drawings referred to therein and one or more claims defining the protection applied for.
2The description must disclose the invention in a manner sufficiently clear and complete for it to be carried out by a person skilled in the art.
3The extent of the protection conferred by the patent shall be determined by the terms of the claims. Nevertheless, the description and drawings shall be used to interpret the claims.
1This Convention shall be open for signature by the member States of the Council of Europe. It shall be subject to ratification or acceptance. Instruments of ratification or acceptance shall be deposited with the Secretary General of the Council of Europe.
2This Convention shall enter into force three months after the date of deposit of the eighth instrument of ratification or acceptance.
3In respect of a signatory State ratifying or accepting subsequently, the Convention shall come into force three months after the date of deposit of its instrument of ratification or acceptance.
1After the entry into force of this Convention, the Committee of Ministers of the Council of Europe may invite any member of the International Union for the Protection of Industrial Property which is not a member of the Council of Europe to accede thereto.
2Such accession shall be effected by depositing with the Secretary General of the Council of Europe an instrument of accession which shall take effect three months after the date of its deposit.
1Any Contracting Party may, at the time of signature or when depositing its instrument of ratification, acceptance or accession, specify the territory or territories to which this Convention shall apply.
2Any Contracting Party may, when depositing its instrument of ratification, acceptance or accession or at any later date, by notification addressed to the Secretary General of the Council of Europe, extend this Convention to any other territory or territories specified in the declaration and for whose international relations it is responsible or on whose behalf it is authorised to give undertakings.
3Any declaration made in pursuance of the preceding paragraph may, in respect of any territory mentioned in such declaration, be withdrawn according to the procedure laid down in Article 13 of this Convention.
1Notwithstanding anything in this Convention, each Contracting Party may, at the time of signature or when depositing its instrument of ratification, acceptance or accession, temporarily reserve, for the limited period stated below, the right:
anot to provide for the grant of patents in respect of food and pharmaceutical products, as such, and agricultural or horticultural processes other than those to which paragraph b of Article 2 applies;
bto grant valid patents for inventions disclosed within the six months preceding the filing of the application, either, apart from the case referred to in paragraph 4.b of Article 4, by the inventor himself, or, apart from the case referred to in paragraph 4.a of Article 4, by a third party as a result of information derived from the inventor.
2The limited period referred to in paragraph 1 of this article shall be ten years in the case of sub-paragraph a and five years in the case of sub-paragraph b. It shall start from the entry into force of this Convention for the Contracting Party considered.
3Any Contracting Party which makes a reservation under this article shall withdraw the said reservation as soon as circumstances permit. Such withdrawal shall be made by notification addressed to the Secretary General of the Council of Europe and shall take effect one month from the date of receipt of such notification.
1This Convention shall remain in force indefinitely.
2Any Contracting Party may, in so far as it is concerned, denounce this Convention by means of a notification addressed to the Secretary General of the Council of Europe.
3Such denunciation shall take effect six months after the date of receipt by the Secretary General of such notification.
