If We Can Keep a Severed Head Alive...Discorporation and U.S. Patent 4,666,425
"Published in 1988, this book also contains the author and inventor’s patent for a device that keeps the head of a mammal alive. A considerable portion of this book provides an explanation as to why this inventor, who is also a practicing attorney, devised a patent he says he does not intend to use. It’s unclear as to whether or not Fleming advocates the practice of keeping severed heads alive or simply wants to explore the possibilities that the marvels of science and technology may provide in the future.
