A trademark is a kind of intellectual property incorporating a distinguishable sign, name, mark, logo, slogan, or any design, which identifies products or services of a particular source from those of others.

Trademark Infringement

Trademark Infringement is the unauthorized usage of exclusive rights attached to a trademark without the permission of that trademark owner. It may lead to confusion, misconception, or deception about the original company a product came from.

Section 52[2] talks about the rights given to a registered user to take proceedings against infringement. “A registered user may institute proceedings for infringement in his own name as if he were the registered proprietor, making the registered proprietor a defendant and the rights and obligations of such registered user in such case being concurrent with those of the registered proprietor.”

If the trademark is not registered, you cannot take any action for infringement of the trademark.

Section 27[3] tells that no action for infringement of the unregistered trademark. “No person shall be entitled to institute any proceeding to prevent or to recover damages for, the infringement of an unregistered trademark. Nothing in this Act shall be deemed to affect rights of action against any person for passing off goods or services as the goods of another person or as services provided by another person, or the remedies in respect thereof.”
