Article 2

1. Subject to the requirements prescribed by this Agreement, the effect of the Classification shall be that attributed to it by each country of the Special Union. In particular, the Classification shall not bind the countries of the Special Union in respect of either the evaluation of the extent of the protection afforded to any given mark or the recognition of service marks.

2. Each of the countries of the Special Union reserves the right to use the Classification either as a principal or as a subsidiary system.

3. The competent Offices of the countries of the Special Union shall include in the official documents and publications relating to registrations of marks the numbers of the classes of the Classification to which the goods or services for which the mark is registered belong.

4. The fact that a term is included in the alphabetical list in no way affects any rights which might subsist in such a term.
