… and no, Canon is not replacing the shutter button with a direct print button.
If you look at area 61 of patent image, there is no shutter button, just what looks to be a touchpad. The touchpad is would have multiple functions depending on what you're doing with the camera.
Before you freak out, I'm sure Canon has learned a lot of about touchpads from the EOS R and how poorly it was generally received. While not a huge detriment to the EOS R, I think a more classical approach to ergonomics would have served the camera well.
If Canon is seriously considering this approach, hopefully, it's thoroughly tested in the real world.
