There are quite some similarities to the V-cube mechanism, but no, this puzzle does probably not infringe the V-Cube patent. I found a patent that seems to describe this puzzle, dated 1980: http://www.google.com/patents?id=dSwxAA ... &q&f=false
In fact, I doubt that the V-2 patent would hold up in court. The patent I cited bears some similarity to the V-2 and might be considered prior art.
Also, Eastsheen's patent for their 2x2x2 might be prior art. The V-2 is essentially an ES 2x2x2 with the straight bits curved, and even the V-cube patent itself argues that this curvature may not be needed.
