 There's four general categories that you can get patents on. The first is a machine, a composition of matters, and a process or a method. That's how software is protected. It's a process or a method. Even a series of steps that have to be taken to conduct a certain dental surgery. A new method that's better for doing a root canal. You write down those series of steps and then as a patent attorney, I look at it and I try to work with the dentist to figure out which of these steps are optional. Which of these steps, if you skipped, could a competitor still do and they identify the skippable steps and then we bring it down to like the bare minimum. And that's what I want to get protection on because now no competitor can follow this process no matter what and you can protect it.
