What patents? They all expired! Radiogel tech is public domain now. RDGL has a single "improved" process patent and has applied for some "improved" application patents, none of which can stop anyone from making Radiogel under a different trademark. Moreover there is no evidence whatsoever of any performance advantages with MK's "improvements".
Again, Betaglue is the company. YntraDose is thier product. Yntradose is in clinical trials killing solid tumors. A dead tumor is a dead tumor. To date, due to MK's gross incompetence, Radiogel hasn't help a single human cancer patient.
