and legal judgments."
Dr. Gary Michelson made clandestine recordings of his conversations with Medtronic. The article also states that
"By putting information about the
property rights to his invention."
Seems a horse vet actually invented the first spinal cage but he presented his idea at a public forum thereby making it impossible for him to patent the idea. It also seems that because Gary Michelson described a method for inserting his cage, he owns claim to anything that is inserted be it a threaded cage or not. In the end this just costs the patient more money.
Just as I thought. Gary Michelson didn't really invent the threaded spinal cage. He was just first to patent it because he is familiar with the patent application. Because he also included a description of the method of introducing it, he owns the patent on any other item someone invents that is inserted in the spine. The full article is not that long and it's very interesting. It's linked above.
