The registration of a trademark is valid just for a period of ten decades. After which, it may be revived from time to time. Renewal of trademark registration keeps those rights that are only available to your registered mark. In the event the owner fails to renew the trademark, then he will lose all of the protection that comes with enrollment. By way of instance, a registered trademark gets the advantage of this legal presumption of possession. That usually means the burden of evidence is on other people to attempt to disprove your possession.
