Its a pretty shrewd move, true, RFMK has the common law trademark on their side, but this move also forces a few things which could easily prove pretty costly and dicey for RFMK and the Cannacig brand, its no where near as easy to enforce common law Trademarks as it is Registered 1s, and I also wouldnt be so sure that THC doesnt have a few more surprises up their sleeve, pretty dumb move on RFMKs part to try and mislead RFMK investors that they were working with THC and their vaporizer last winter, kinda like poking a dragon in the eye.
