Unlike Patents, Trademark does not have any definite period of limitation. Where any Patent expires in the time period of 20 years a Trademark Registration in India expires after 10 years' time period of its registration. But on the other hand, unlike Patents, a Trademark can be renewed again for another time period of 10 years. This Trademark Renewal process can be indefinitely done, meaning as long as the trademarks owner keeps renewing a Trademark it will not expire and will also continue to be under the protection of the Trademarks Act, 1999.
