If the disc spins faster the longer it goes how do you stop it?

It spins SLOWER the longer it goes (Precession). It sounds like it is spinning faster due to more of the disk laying down flat before it comes to rest.

Does anyone have a video of this in action?

Here is a YouTube video of a Euler's Disk https://www.youtube.com/watch?v=rFtYzVJcWyA

How do you patent a steel disk?

A design patent on the visual design elements is the most likely answer. A utility patent on details of the disk that optimize its action (such as a specific combination of edge finish, weight distributions, etc. is remotely possible, but IMHO, very unlikely.. The third type of patent is.a plant patent, which is what Monsanto (not Moderna) gets,. I’m pretty sure it refers to a design patent.
