So, when your artistic work is capable of being registered as design, then it cannot be registered as copyright, in case certain design protocols on it have already been applied! And when the artistic work is to be registered as copyright, the work which is also registered or is capable of being registered or used as a trademark, then you would require NOC from the trademark. Herein the dilemma originates, on which I had also written couple of blogs long back. Also, a trademark cannot be registered if it is protected by copyright.
