You've got to be kidding me. The title is "Computer with keyboard" and from the description it looks like a rubber keyboard protector over various types of switches, including the butterfly ones. I don't really get this whole IT patenting business.
Yeah, the patenting stuff is pretty terrible business.... The patent itself is rather interesting though. The "protector" is not rubber but deforming glass and it can be laid over a "normal" keyboard. If done properly, you could have the same tactile feedback as a keyboard with regular switches, but in a device that's much better protected, with more stable "keys" and of course you can add e-ink or other kind of displays as key glyphs.
I am rather sceptical of this ATM of course, but it just might work.
