They already applied for Dum TV Kannada Logo trademark registration. But status is "objected".
No problem with "objection". They will use the logo after objected by Ipindia
R. Bangla, NKTv 24x7 etc. Logo's also objected by Ipindia but they used the logo.
It is like GoAir putting a big newspaper ad that they have rebranded to GoFirst, but there is no change on the website, on social media, and above all on the planes.
Of course, Dangal Kannada is not on TS so that is a huge concern.
