New Trademarks are getting registered all the time. Some of them might infringe your already registered mark.
You should actively defend your trademark. When a new Trademark — that infringes your mark — is 'Advertised before acceptance' it is easier (& cost-effective) for you to oppose and protect your Trademark.
New trademarks are advertised exactly for this purpose. When no one opposes, a potentially infringing trademark may be officially registered. Thereafter it will be a long legal process for you to protect your trademark.
Our Trademark Watch Service will search new Trademarks advertised by Indian Trademark Registry and present you any possible matches. You are free to decide your next course of action.
