My thoughts on this topic and thread:
1. I'm yet to see an argument put forth by the pro-original crowd that will reasonably prevent the pro-clone crowd from buying clones. As I think this point matters, I list it as #1 and will come back to it later.
2. If authentic makers had to argue their case with pro-clone crowd, in this thread, I think they would win in a heartbeat. IOW, let the courts settle the legal debate. I'm glad it has finally come about.
3. Regarding post #60 in this thread (by Marc411), where it conveys idea of 'unless copyrighted (or patented), it is okay to copy,' then I wonder why not just copy the logo? I would wonder from the pro-clone crowd, why some imaginary line would be drawn if the logo was copied but that logo was not copyrighted/trademarked? If I make 1:1 copy of Provari (for example), including their logos, but those items are not copyrighted/trademarked, and person selling it says this is a Provari clone, then what really would be the problem if filtering this from the pro-clone crowd perspective?
4 - Regarding post #89 of this thread (by bluecat), the dictionary definition of 'counterfeit' that you linked to, includes the definition of 'imitation.' Intention is one definition of counterfeiting, but not the only. Google 'non-deceptive counterfeiting' if you are unclear on how, precisely, cloning is actually counterfeiting.
5 - I don't see authentic makers entirely winning in courts. I think they may win on some counts and in some jurisdictions, but not all counts and not all jurisdictions. This is really US economic law clashing with other governments on issues of innovation and ownership (of design patents, copyright, trademarks, etc.). To the degree the authentic makers do lose, it will benefit consumers of the product, but will hurt foundations of US economic law. Perhaps that's a good thing depending where you reside physically and philosophically.
6 - Coming back to point #1, and politics of vaping. As long as China is able to put out clones (non-deceptive counterfeits) and no one on the planet can prevent them from doing this (including distributing those counterfeits into US markets), then I don't see how FDA can possibly win in its fight to eliminate vaping products from the US market. So, say FDA succeeds in closing US businesses due to deeming regulations. Does this mean China will just sit there and change their tune on how it manufactures and markets its product? I would say a resounding 'no' is the answer to that. This means, the black market for vaping is virtually guaranteed and those who suggest FDA will get rid of 99% or more of all products know very little of what they are talking about.
