I was looking at the new company LeapMotion and did some reading and it occurred to me that it looks like there is a patent from 2012 out there involving this subject - noting that the filers are not LeapMotion.
The patents in questions are: 20120287044, Processing of Gesture-based User Interaction Using Volumetric Zones and 20120317511, Display with built in 3D sensing capability and gesture control of a tv.
These patents are clearly too broad and we are looking here at yet another discipline that is going to be under litigation repeating the same experience with most other fairly new software development projects. There is nothing in these patents that i can see that talk about how we are going implement our own version of these processes - rather painting a broad stroke of just patenting the whole process. My concern is that this means no one else can make their own version of this in the future.
Lastly, somewhat i think this may be prior art. Kinect, for example, uses these types of ideas but just not in 3D. So here we are trying to get a patent on an implementation of something that has been done in 2D but since its 3D its "oh so inventive".
Would request any input or feeback. thanks.
