How about a full-frame four thirds from Olympus or Panasonic?

4/3rs can never be full frame. it's maximum size is what it is. it can
never be any bigger.

4/3 is an artihmetic ratio - unless it's been registered as a
proprietary name (which I doubt), it can be applied to any rectangular-
shaped object that satisfies it.

I'm guessing Four Thirds is in fact a registered proprietary name.

4/3rds has been registered and it's based on the *size* of the sensor,
not (just) it's aspect ratio.

full frame means a 24x36mm frame, the standard 35mm film frame, and
it's a term that began 50 years ago when olympus came out with a
half-frame 35mm film camera.
