LOL... if it has a voltage regulator and a means to adjust it, and it's used for vaping it does, that's covered in several of the claims... If it looks like a baseball, or a set of monkey bars and it has a voltage regulator and a means to adjust it, and it's used for vaping it... it's protected under that patent...
You've singled out individual claims that the REO does not match... the point of the patent is protection against the features that DO match... and if there is a REO with VV, and it uses a buck/boost or linear regulator, it's a VV PV covered by this patent.
Edit: I think Mike can back me up on this claim... Intelectual property is a hot button for me, and I go toe to toe with Patent attorneys in my daily grind... I'm going to distance myself from this thread for a bit before I catch myself a perma-ban for saying something I should avoid saying...
My parting shot will be that IP is important to protect, and the patent office does a pretty good job of deciding if a patent is deserved for an invention. If the patent issues, it will be because Mike deserves it... no other reason.
