If this is a valid patent, then I'm currently using an infringing product from a base reading of the claims.
I'm on a windows PC with 2 screens attached.
However this tech has been around for a while and i think before the year 2000
Patent application and approval is a mare's nest of bureaucracy, loopholes and shenanigans. There's SUPPOSED to be systems in place to prevent patents as general as this (I mean, the patent is not restricted to operating system, for heaven's sake), but over the years it's become a complete mess. Unfortunately there's not a real easy solution to fix it, either.
The US patent office is broken, due to its setup and who is in control of it (I believe the patent office isn't independent its under the department of justice remit) they tend to rubber stamp to a degree and let the courts decide. Even people in the industry see the US system as a bit broken
[EDIT]
I'm reading through the claims (the bit that matters, the abstract etc are written to confuse, the claims are the important bit), at no point does this patent mention broadcasting the signal wirelessly, this fact is a novel idea, therefore would be a new technology , therefore the patent has no claim because the tech is different. It should be shot down quickly except for the whole US protects their own thing. It also seems to be about duplicating the video, the pad of the WiiU is independent, it has its own video stream, the closest thing to WiiU tech I can see that they will get them on is duplicating the image for the games that do that, but that is copying memory and should not be patentable.
It even mentions at one point
"The multiple monitor video display method of claim 1 comprising steps of:interfacing the user with the computer program; modifying content of the first processed video data signal and the real time display through computer data entries submitted by the user; maintaining the first predecessory video signal unchanged; and, presenting the unchanged first predecessory video signal on the secondary monitor as the predecessory display; whereby the first monitor may be referred to by the user for a primary viewing of the realtime display and the second monitor may be referred to by the user for a secondary viewing of the predecessory display."
... which is basically setting your computer to mirror mode, which MS has had for a long time (windows 2000 i believe)
This is ignoring that all of the drawings associated with the patent show a box BETWEEN the computer and the screens, as in an extra thing, which again Nintendo don't have, the box is the computer.
Oh and this patent has been subject to 2 surcharges for late payment, and the patent was seemingly transferred to this company midway through 2012.
These guys have no leg to stand on IMO but I AM NOT a patent searcher OR a patent lawyer or anything like that so this info is my own opinion (I do have access to some patent searching tools hence I can dig out some extra information but I'm not licensed or trained in reading/writing patents or anything like that)
