I don’t think you can patent how one independent machine interacts with another. Especially what tasks a robot performs.
Correct me if I’m wrong.

Unfortunately I am not a patent attorney, I am just biased from the many things that I have seen patented.
I agree with @Markus_Seidt After looking at the printer closer the automatic build platform isn’t the interesting part. It’s the fact that it can print something infinitely long in the y axis (theoretically of course). I saw a printer that works this way at MRRF by Bill Steele from Polar 3d. He told me he created it a few years ago. What is cool about this concept of printer is that the bed not only moves to eject the part, but it also acts as the y axis of the printer. Hackaday did a writeup on it as well. I thought Bill was still in this group, but I couldn’t find him. The coolest thing I saw he printed was a chain. It could print a continuous link of chain as long as you need. I wish it was open source

And as the belt acts as z-axis it doesn’t have to be fast.

I talked to Bill at MRRF about his printer. First, he’s an awesome guy. Second, he gets his Printrboards from us. But more to the point, he said the patent mentioned the bed had to be perpendicular to the hotend (z axis). By tilting it, it’s not a violation. Assuming he is right, Cool!
