This is sad news. Hopefully they won't succeed. Blockchain/crypto currency was meant to be free and decentralized.
I hope these guys will just let Bitcoin be and get their hands off our decentralization/financial freedom because filing for patent in order to own and control the blockchain or a blockchain is a dangerous development against us and we ought to curb it somehow.
Those greedy banks feel threatened by decentralized financial systems, because it is outside of their control. Sadly, that is why they have relentlessly tried to gain control over it. Hopefully they will never gain control over any blockchain/crypto currency.
