Back in the old days the company had a product,I think it was called MMRPro or something like that,I think some posters even use to put up pix of company employees installing them in dr.'s offices,lol,..it used to be all the rage w/ talk of machines sold,doctors and hospitals ordering them...but that was eon's ago..I think nowadays they are mainly a patent protection and litigation consortium....not sure if you can get a P/E outta that or solid sales numbers but speculation and patent worth is infinate.
