Trademark registration grants legal protection to brand names, logos, symbols, and slogans used in trade. Under the Trade Marks Act, 1999, registered trademarks prevent unauthorized use by others and build brand recognition. The process involves searching for name availability, filing the application, examination, and eventual registration. It gives the exclusive right to use the mark and helps enforce rights in case of infringement. Registration is valid for 10 years and can be renewed indefinitely.
