## What is the class mark of 25 - 35?

Solution: By using the class mark formula, we have, Class mark = (upper limit + lower limit)/2. The given class is 25 - 35, where 25 is the lower limit and 35 is the upper limit.

## What is the purpose of the Nice classification?from wipo.int

Each of the countries party to the Nice Agreement is obliged to apply the Nice Classification in connection with the registration of marks, either as the principal classification or as a subsidiary classification, and has to include in the official documents and publications relating to its registrations of marks the numbers of the classes of the Classification to which the goods or services for which the marks are registered belong. Use of the Nice Classification is mandatory not only for the national registration of marks in countries party to the Nice Agreement, but also for the international registration of marks effected by the International Bureau of WIPO, under the Madrid Agreement Concerning the International Registration of Marksand under the Protocol Relating to the Madrid Agreement Concerning the International Registration of Marks, and for the registration of marks by the African Intellectual Property Organization (OAPI), by the Benelux Trademark Office and by the Office for Harmonization in the Internal Market (Trade Marks and Designs) (OHIM).
