I am interested in this project and have made a contribution to the Pre-sale.
I was sceptical however about the pretty aggressive marketing of it with a too rich Referral programme.
But I am coming round to the idea that it is a genuine project with great potential.
Here is the patent registration of the KeyCAPTCHA system by Nicholas Prays, the founder of STEX.
https://www.google.com/patents/US20120323700It's important to note that this is just an application. A quick lookup on USPTO will tell you that it was REJECTED and never granted. It failed to pass the requirement of un-obviousness and novelty.

Moжeшь пpocтo eгo cпpocить имeл ли oн дeлo кoгдa-нибдyь c USPTO и знaeт-ли pacцeнки US юpиcтoв? 🙂

И кaждaя итepaция этo $ 4000-7000
Translation:
Have you ever done any business with the USPTO and do you know how much US lawyers charge? Every iteration costs $4000-7000.
Secondly, do you ever have any idea how much Keycaptcha earns a month?
After answering these questions you may rethink what you have written.
Our patent was abandoned after failure to pass two out of the three requirements for patent filings. Even though we "make a shitload of money", it's still not enough to pay for a US patent lawyer.
Who cares what your reason is? Doesn't change the facts. What are you scared of?
