So if I understand well, according to the patent description, all market makers allegedly make use of human beings to fill customer orders if there are no matches in the open market. And the whole point of the patent is to replace that alleged human being with a program, called Virtual Specialist.
Again I personally find it very hard to believe that:
1. No other market maker in the world, of whichever financial instruments, wouldn't already be using automated processes to achieve such matching.
2. A patent could forbid anyone from deciding to make their own little program to achieve such matching.
