Unless/until the '330 patent is ruled invalid, they DO own it, and anyone else who makes such devices and sell them in the USA risks being sued for infringement.I read the pleading. If Evolv were suing because Wismec made an exact copy of their board and was reproducing it without license, I would support them. But they're not. Evolv seems to think they own the "variable wattage personal vaporizer" application in entirety, and nobody else is allowed to make a VW PV of any kind.
