How are designs classified?

Designs are required to categorized in separate classes in order to provide for systematic registration. An International classification of Industrial Designs according to the Locarno Agreement has been introduced in the Design Rules 2001 & in Design (Amendment) Rules 2008. There are classes and most of the classes are further divided into sub-classes. The classification is based upon the function of goods i.e. they are mainly function oriented. In some specific cases, the function of the article is required to be mentioned along with the name of the article in the application form for the purpose of classification.
