Opinions on a 2-Battery Mod

[ShowerHead]

I'm thinking a 2-battery mod would be more ideal. I'm just not sure which one to get.

hcigar VT133. Great little dual battery dna 200 mod.
I've had various mods at all price ranges. This one is the best vape I've had.
You can get it for around $80 if you look. Try Ecig.

"We will not use this patent to go after other companies and hurt the industry, We only did it so a patent troll wouldn't do that" - Evolv in one of their videos

I thought I read that they went after Joytech because they reverse-engineered the DNA RX200 without Evolv's permission and sold it for 1/4 the price of the DNA model.

It's a fine line when it comes to patents. Even if you want to be nice about it, you still have to act as the patent holder to defend yourself against infringement, otherwise your patent claim can become "invalid", or unenforceable against future clams. I don't know anything about that particular lawsuit, but perhaps Evolv felt the infringement was simply too blatant to ignore.

I think Evolv will end up having their patent disolved.

They are effectively trying to patent digital voltage regulation which has been around for decades. Their "tech" is really all prior art that's just been repurposed for vaping. They don't even have unique chip designs, what they have is a custom PCB board that uses off the shelf general purpose chips and their own programming. It would fall into the classification of both "prior art" and an "obviousness". That being that it's based on existing voltage regulation technology and is an obvious solution to the issue of regulating power output in an ecig.

Technically a variable wattage mod is operating exactly like a car stereo. Your car stereo can detect whether a 2ohm or 4ohm speaker is connected to it and changing volume adjusts the voltage to reach the desired wattage output of the speakers. Replace the speakers with an atomizer and you have a variable wattage ecig.

I don't know what their patents look like, but I would expect the code, as well as the Evolv software package, would be protected. But the idea of voltage regulation itself would hardly withstand a challenge. You're right, it's used in other applications that its generic implementation for a variable voltage mod would not seem terribly original. Still, if they have some original code which would differentiate their product from others, they might have something to hang on to.

Patent law can get so arcane it's difficult to be sure what will and will not stand up to scrutiny. Look at Apple and Samsung. Is a square with rounded corners on the screen really all that innovative?

It's Wismec's box. The chip's entirely different so I don't know what they stole.

That's the problem, their patent is actually pretty vague. It doesn't get as deep as specific lines of code, chips, or even operating parameters. It's basically an all-encompassing patent that could be applied to any device that reads resistance and then alters voltage to achieve a user specified wattage setting based on that resistance. Digital light dimmer switches and car audio amplifiers could fall under the patent as it is written.

I thought when the news of the lawsuit broke it was discussed and determined it was the variable wattage technology that was the issue?

Fuchai 213, Minikin 1.5, and the Vt133 are all good 2batt mods for my use. I still use my Fuchai 213 the most.

They are out of stock because it was such a great sales price. Also out of the Fuchai 213. I am on the email list for both...
