[Rhetorical]

From an intellectual property standpoint, I believe it is reasonable to assume the two are completely unconnected until evidence can be shown otherwise. I'm not aware of any evidence that the Wyss Institute of Harvard has contributed anything they have learned or gained in their DARPA contract to assist or collaborate with ReWalk.

In fact, it is quite possible the Wyss Institute's DARPA agreement explicitly does not allow them to talk about, let alone use the technology they are developing for the D.O.D. in consumer products, like those they are working on with ReWalk.

If you look into the terms of government contracts you will find that the government has most of the authority and control over whether or not the party they contract can use a patent they are granted while working on their government contract, for commercial purposes. However, generally it is the government's goal to allow the companies to do so. See:

I'd appreciate correction if I'm wrong about any of this
