In the third Schedule of Design Rules, 2001 the classification of goods has been mentioned. The classification is based on Locarno Agreement. Only one class number is to be mentioned in one particular application. It is mandatory under the Rules. This classification has been made on the basis of Articles on which the design is applied.
Practical Example: If the design is applied to a toothbrush it will be classified under class 04 & subclass 04-02. Similarly, if the design is applied to a calculator, it will be classified in class 18 & subclass 18-01. Subsequent application by the same proprietor for registration of same or similar design applied to any article of the same class is possible but period of registration will be valid only upto the period of previous registration of same design.
