A trademark is a unique identifier, often referred to as a “brand” or “logo”. Once a trade mark is registered, the ® symbol may be used with the trademark. A Trademark is thus an intangible property of its owner and the owner has the authority to enforce it in the case of unlawful uses. A Trademark can be in various forms like Logos, Words, Shapes, Sounds and Smells-or any combination of these.
Trademark has no limited term of existence, the rights to use it may be lost due to misuse or lack of use. Trademarks are divided into 42 international classes, each class representing similar goods or services. Whereas a trademark may be registered under multiple classes, it is protected only in the class(es) relevant to the business or trade area of the item.
