Believe what you want but the fact is there are plenty of surgical robotic patents by Ethicon and SRI. Ethicon has the most robotic patents after ISRG. They are easy to find and longtime readers here know that. Does Ethicon have a patent for a patient cart? No. Does Titan? No. These companies have patents for elements of their design and function. Ethicon has dozens of them. Also have an army of robotic engineers. I guess we have to revisit this from time to time. I don't get it. Maybe we partner with Verb soon. That would be great.
