The only thing that I can see can be patented in this product is real time conversion software. Depending on the lpi of the lenticular, you can make you own 3D monitor out of an LCD.

Phillips patented the titled lenticuar design several years ago, which has the advantage that, when producing nine views, it cuts the resolution by 3 horizontally and 3 vertically, instead of 9 horizontally like a normal straight up and down lenticular lens. 3X3 looks better; the resolution drop is not as obvious.

The interesting thing is that Stereographics has been using such a tilted lens for the past few years on its Synthagram monitors. One of their people told me that they were doing so without a license because they found old published descriptions of this type of lens that would invalidate Phillips patent.

Real time 2D-3D conversion is hardly unique. Everyone under the sun seems to have a version nowadays. Most of them suck.

Hehehehe. I read through their patents. Most of it has been using by the 3D printing industry for ages. The lenticular design is the claim that is relating to the way they layout the lenticular sheet which I think is patentable along with the way the views are combined. The problem is; how the heck are they going to market it to gamers which I think is the biggest market for 3D displays. There is just no video card currently can render 9 different views for the same scene, and have a decent update rate. However, I do think their display will be cheapest around, and it is good for playback video that have the different view already available.

BOPRay:
According rendering 9 view in the same time - keep in mind that each frame has 1/9 resolution of the full frame witch gives additional speed (lover filrate). In addtion key parameters of all view are usualy pre-computed and stored in videomemory - aditional speed up. Combination of the 9 view into the final patern could be easy done in HW as well. I had done several related tests and I do not see any key problem with 9 view rendering at 30 fps + autostereoscopic pattern creation. I speak about e.g. one year old games and recent graphic cards (witch are enought overpowered).

Ive been using a stereographics screen for 2years now. They actually shipped me the monitor with a crappy AtiRV100 card that played pre-rendered 9tile video a 8-10fps on a pIV 2.4ghz machine!
Well things have come a long way since then.
I now can run fullframe (1024x768) 9tile video at 25(Pal) fps on a Geforce Ti-4800 videocard on a PIV3ghz machine.

However whats interesting is, that on a PIV 3.2ghz and a nvidea FX5600 card with pixel shaders and 256mb onboard ram, people like x3d and even stereographics have now got software using Directx9 to interpolate in realtime the "interlaced final image" from 9tile video.

But then again ..will 3d game engines be able to "run" 9 virtual cameras, create the 9tile video and interpolate to a full sized 1024 x 768 interlaced pattern "everytime" *without* stuttering?
I cant say I have tried that yet, as there is no game to my knowledge doing that.
Most other autostereo screens have this camera eye tracker thing going on, so they are actually only displaying a standard stereo view and shifting that view to match the players head position.

What would really kick ass tho is something im working on with my limited knowledge of computer coding (almost 2%) i.e. a 9 camera array to do live video on these monitors.
Cheers
