Large System = “miraculous unproven device” + Subsystem1 + SubSystem2 ?= PATENT? Thank you, George. Indeed, I have considered working with the patentee. Side note for a disappointing day: seems that the whole patent system motivates nebulously defined half-baked patents that SOUND or SEEM credible. Seems also that the author of the old Dick Tracy cartoons could have patented the Mobile Phone (or wrist watch radio) back in the 1930's if he had gotten past a patent examiner. Thanks again.
