While I have no comments on the above conversation - again, I am an advisor for blockchain technology with Jetcoin, so my duty is to advise on technical solutions hoping to be listened - I find quite questionable the way things are managed.
Just for the sake of it, here are some other dates (it would have been an easier claim to make, rather to pretend to have patents that can't be proven):
Domains registrations of the original Jetcoin:

Domain registration of the clone:

So, beside the silly way of handling a dispute, if we go down to facts, unless I am missing something on the clone side, the clone it is clearly a clone that is using the publicity cash spent by the original Jetcoin to get traction. IMO.
The logo are also somehow similar...

Now, while the word "Jet" and the word "coin" are very much used, and this can be a real incident and not a premeditated cloning, one thing I do now for sure, is that the "original" jetcoin has loads of cash to spend in legal fees, so I really hope it will not go in that direction

Jetcoin Institute has spent a lot in advertising in the past year and it is an easy claim to say someone else is both enjoying that promotion as the name is similar, and claiming damages for the image. The copyright law - if I recall correctly as I am not an expert - claims that when no registration is made the first public appearance of the brand (in a newspaper, fro example) is a valid claim for a copyright.
