Accenture is a consulting company that works with governments and big businesses and I think this is a brilliant move for them. Governments and big businesses are very interested in and want to use blockchain technology - but with the caveat that they want to have control over it.
I can't see any big corporation or government using a blockchain technology that they don't have 100% control over. If they make a mistake (which they will) they need to be able to go in and fix it. They don't care about decentralization or the philosophical goals behind cryptocurrencies or really anything else other than making money (which, in the case of a business, is their fiduciary responsibility to shareholders, whether we like it or not).
If Accenture can patent this then they can become the go-to consultant for businesses and governments who want to get in on "blockchain" technology which will be a huge business for them.
