Article 11

1. [The right; its period] Any breeder who has duly filed an application for the protection of a variety in one of the Contracting Parties (the "first application") shall, for the purpose of filing an application for the grant of a breeder's right for the same variety with the authority of any other Contracting Party (the "subsequent application"), enjoy a right of priority for a period of twelve months. This period shall be computed from the date of filing of the first application. The day of filing shall not be included in the latter period.

2. [Claiming the right] In order to benefit from the right of priority, the breeder shall, in the subsequent application, claim the priority of the first application. The authority with which the subsequent application has been filed may require the breeder to furnish, within a period of not less than three months from the filing date of the subsequent application, a copy of the documents which constitute the first application, certified to be a true copy by the authority with which that application was filed, and samples or other evidence that the variety which is the subject matter of both applications is the same.

3. [Documents and material] The breeder shall be allowed a period of two years after the expiration of the period of priority or, where the first application is rejected or withdrawn, an appropriate time after such rejection or withdrawal, in which to furnish, to the authority of the Contracting Party with which he has filed the subsequent application, any necessary information, document or material required for the purpose of the examination under Article 12, as required by the laws of that Contracting Party.

4. [Events occurring during the period] Events occurring within the period provided for in paragraph (1), such as the filing of another application or the publication or use of the variety that is the subject of the first application, shall not constitute a ground for rejecting the subsequent application. Such events shall also not give rise to any third-party right.
