Applicant: the breeder or his successor in title. The applicant can be a natural or legal person resident in an EU country, a natural or legal person of the UPOV or a country granting reciprocity. Foreigners: non-EU residents shall appoint a Slovenian representative. Conditions for protection: the plant variety shall be new, distinct, uniform, stable, and denominated in compliance with the provisions of the Act. Novelty: the variety is deemed to be new if, at the date of filing of the application it has been sold or economically exploited with the consent of the person entitled in the Community, not earlier than one year before the filing date, and in a territory other that of the Community, not earlier than four years before the filing date or, in the case of trees or vines, not earlier than six years before the said date. Distinctiveness: the variety is deemed to be distinct if clearly distinguishable from any other variety, whose existence is a matter of common knowledge at the time of the filing of the application. In particular, the variety is deemed to be generally distinct if it has been granted protection or entered in an official Register of varieties in any country or in the Community by that date, if an application for variety protection or for entry into the Register of varieties has been filed in any country or in the Community, provided that the procedure leads to granting of protection of the variety or to the entering of the variety in the official Register of varieties, or if propagating material or harvested material of the variety has been marketed or used for profitable purposes by that date. Uniformity: the variety is deemed to be uniform if, subject to the variation that may be expected from the particular features of its propagation, it is sufficiently uniform in its relevant characteristics. Stability: the variety is deemed to be stable if its relevant characteristics remain unchanged after repeated propagation or, in the case of a particular cycle of propagation, at the end of each such cycle. A variety, which has been applied for a plant variety right in the Community or protected according to the scheme for plant variety rights in the Community, may not be subject to additional protection.
