I seriously wonder how that wiper design will stand up to ice-buildup in winter prone states.

4runner has the wiper in the same location (at least the older generations did) and I didn't have any issues with mine.

Says something about a heating element in the patent.

I was going to say, if it is tucked away in that recess, prone to snow and ice accumulation, freezing rain, etc. It will need a heating element somewhere for sure.

Older 4runner does have the wiper below the rear window but it is exposed so any water would not be captured inside a recess like the R2 design shown here. Newer 4runners have the rear wiper hidden above the window.

Cool find, this is a more elegant design as long at this doesn't increase the cost or make the wipers harder to replace.

Not a patent expert, but hopefully the wording of "may" include drainage and heating elements actually means "will" include. It would be silly to have this design and not account for rain, snow, or leaves.

Would be easy to add a rear wiper service mode to move the wiper arm a little way above the resting position.

Most likely will be a wiper service mode just like the front. The pocket the wiper sits in will probably have a drain hole and tube, not a big deal. The gate itself already need a drain... just like all of the doors.

Wait, am I the only one nerdy enough to be bothered by the fact that the coordinate system depicted in the patent is left-handed?

Probably
Is that an auto industry or patent norm?

Patents _do_ have their own language, but I don't think it extends to using a left-handed coordinate system. It doesn't really matter unless one uses the patent as a guide to cut a thread. It's just troubling on an abstract level.

Has anyone discovered where a spare tire might be located?

Older 4runner does have the wiper below the rear window but it is exposed so any water would not be captured inside a recess like the R2 design shown here. Newer 4runners have the rear wiper hidden above the window.

hidden above is a better design all the way around. Nothing for leaves or other debris to accumulate on.
