Google Translated Link (egami)
I don't read japanese, so I'm relying on the job the translator does to the site. It looks like a lens mount adaptor. If/when Canon enters the mirrorless market, I am pretty confident they will have an EF adaptor for such a system.
This is the first patent I've seen that has even a remote chance of being about a mirrorless camera from Canon.
