LOL.. so not only are they using a patent on something free but it is a bad idea, see the patent itself and this part:
"The system of claim 1, wherein the allocating the subset of the first user secondary wallet private keys to the second user includes: encrypting the subset of the first user secondary wallet private keys to provide an encrypted subset of the first user secondary wallet private keys; and transmitting the encrypted subset of the first user secondary wallet private keys to the second user. "
So what we do is we send the second user the keys from the first user's wallet and call that a transaction.. except the first user still has the KEYS and the wallet is now insecure by design.
LOL.. this is what you get when you have a dinosaur innovating tech.
