I agree. I did a search and came up with this:
The chip on the left is RX200, the one on the right is the DNA200. They look like totally different IC boards with a generally similar form factor. The DNA has a bigger screen, looks like a lot less IC's. So, if they plan on suing for copying them, then they're wrong. My case....
George B Selden Vs Ford. Selden had a copyright on a motorized four wheeled vehicles. for some time, everyone payed him a royalty or suffer court fees. Ford challenged them, and won. If it weren't for Ford, then the industry probably would've stagnated for quite a few years, and many companies wouldn't exist.
I think the RX chip does offer a variable wattage/temperature device in the same range. However, looking at the two different chips side by side, they do it in a totally different way. just like my analogy with the cars, same general idea, different approach. I sure hope Evolv doesn't win this one... It'll be another banned item like the Ameravape.
