That surprises me -- they make a lot of money from swaps and other non-exchange settled contracts' volume, especially if such contracts can be traded easily across banks. MarkItPartners is an excellent example of how all the banks made a lot of money through a consortium pushing a unified standard. Why try to make money off a patent when they can grow volume on their core product?
because they would love to unilaterally control critical pieces of next gen digital currencies enabling them to bludgeon competing standards / companies out of the market with IP licensing fees.
