Sorry to resurrect an old thread, but I found this on a google search and thought I'd share what I've discovered for those who come after me...
The patent appears to belong to Microsoft (Patent US 8040331 B2) and is licensed by Logitech. It stands to reason that Corsair (or any other peripherals manufacturer) could license the same patent and engineer their own solution.
Honestly, this is the only reason why I don't own a Corsair mouse, especially since the recent release of the Scimitar RGB in black.
