I'm no expert on patents but trying to patent "3 pins or more" meaning no other coil maker can make a mesh coil with anything but two pins sounds a bit silly to me. If you've made a 3 pin coil and it's a unique idea and nobody else ever has and you can patent it - have at it. But 3 pins *or more* doesn't sound right to my ears. They haven't made more than 3 so why should they own that idea purely off the back of making a 3 pin coil?
when i first read this thread i had check the date just to make sure it was not the 1st of april & tbh i dont think vapefly have got a chance & find the whole thing kind of ironic given what china think of copy rights lol.
