Trademark registration helps establish ownership and protect the brand of an entity. Early trademark registration will help avoid unnecessary legal issues. The trademark application is made under 45 different classes as per the NICE classification for the trademark. Each of the trademark class represents a distinct set of goods and services. While filing a trademark application, the class of goods and services to which the trademark pertains must be mentioned in the application. It is important to choose the right class of trademark while filing the application as the wrong classification of the trademark could hamper the trademark registration process and/or diminish the legal protection for the mark under the Trademark Act.
