It is apparent that you have done a lot of work on this. That's great.
But do you or anyone happen to have the Patent number or numbers? With those I can do some research through the US Patents and Trademark Office.
I am not saying you are wrong but I am not comfortable with all of this yet. I'm very curious how any medical billing software can operate without human interface. If this is the patented element of the PPJE software, then the patent application and approval will have to lay this out in detail.
