I'm not a patent expert, but I suspect there is just way too much prior art. Pushing a tube or rod with a pair of wheels is extremely obvious and you can find such arrangements everywheree.
Mig welders, for example, use a virtually identical mechanism to push metal wire through a bowden tube where it can be melted onto the workpiece (sound familiar?).

If its is patented, dyze design have infringed on the patent (as well as printrbot) as they also use a dual drive design. I dont think its patented but as far as I'm aware they went closed source. I dont think you can patent something as straight forward as the number of hobbed gears used to push filament. Plus, as 691 said, mig welders have used similar systems in the past and i believe so has stratasys. If anyone would have patented it, it would be stratasys.

Well I suppose you could search for their patents, or make one and start selling it an see if anyone sues you.

Hahaha, stratasys sharing rights to their patents. That's funny.
EDIT: Didn't mean to sound rude, though I don't think stratasys would have licensed it out. They might have bought bondtech and started selling the gears (like they did with makerbot and the replicators), but I don't think they'd have licensed it out. Bottom line, I don't think it's patented, a number of companies do it and there are plenty of ones people have published, plus it's used in a number of other industries for similar purposes.
