To get the protection of trademark rights one has to register the trademark. It is important to register your trademark because it prevents others from copying your mark and misrepresenting other products with your mark. Trademarks help the customers to recognise the brand and the brand value in one look such as the logo of a tick sign for Nike or a jumping wildcat for Puma etc.
Unlike patents, trademark does not have a definite limitation period. Where a patent expires in 20 years a trademark registration expires after 10 years of its registration, but unlike patents, a trademark can be renewed again for another 10 years. This process can be indefinitely done, meaning as long as you keep renewing the trademark it will not expire and will continue to be under the protection of the Act.
