Hi If you know the names of competitors who are violating your trade mark, you need to do the following: a) first purchase from a local dealer the product sold by the competitor. please ensure to take a bill with full name of product in the sales bill with the product. b) Then you need to issue an "Infringement and passing off notice" to both the local dealer and the competitor asking to desist forthwith using the impugned trademark, color scheme, label and carton. You should give 30 days time for both of them to respond to you . then irrespective of whatsoever said by them in their reply, you should file for a suit for permanent injunction restraining infringement of trademark,, copyrights, passing off, damages, rendition of accounts etc in the district court. Hope this helps.
