After a first appearance at the US patent office, and with enclosures showing up, we’re hearing once again about that rumored sideways docking iPad.

This time around, Patently Apple spotted another patent application for the concept at the European patent office. This one doesn’t tell us anything more than the US patent we’ve told you about. Yet, as Patently Apple points out, this one was filed very recently; on September 25th. Also, it’s signed by Steve Jobs himself, as well as, the great Jonathan Ive.

Is there anything to it? We still don’t know. Engadget contends that this is nothing more than a prototype idea that never went into production. Nevertheless, it’s still a very good idea, and who knows, it might make a comeback in the next generation iPad.

What do you think?
