You are. Using UV to cure photo-sensitive resin isn't the innovation, it's using the oxygen permeable membrane.
If you look at the Form 1 printer or the B9Creator, there's a mechanical step between every layer where it needs to actuate the platform in order to loosen the resin from the projection window, so it can build the next layer. In the Form 1, it peels the print off, and the B9Creator slides a window. (look for videos on youtube.)
In both instances, the amount of time spent actuating the mechanical part adds up, and results in a significant amount of time spent in the print actuating the plate. What the oxygen membrane allows us to do is to skip that step between every layer, and simply keep shining a continuous changing image slice of the object as we're pulling the object out of the resin.
Not only does this have the advantage of speeding up prints by orders of magnitude, in materials, the grain of the object influences the type of thing you can built. If you print a stress holding object with the grain orientated in the wrong direction, the part will fail very readily. This way, we have greater design freedom, without worrying about grain direction.
