This has already been addressed in this thread by those who have actually taken the time to read the patent.
The patent is for the modular interface on the housing. The claim is narrow enough to where the only thing that is patented is not the cables or the fact that they're removable, but the fact that there is an interface on the housing that allows the cables to be modular, ergo, removable. It's also stated in the patent that this is for a device that is inside a personal computer and that the removable cables are those that supply DC power to other devices inside the computer.
I know the legalese makes it difficult to understand, but it is all right there. It's not as vague as some people here are making it out to be and it's not an "old idea" that Ultra just decided to patent.
i did read the article dude.. i and i still dont see the the idea of plugs and sockets on the AC (inside) of a bloody PC psu as original..
call it what u like its plugs and sockets stuck on something that previously didnt have plugs and sockets.. very original..
ultra might be the first to be cheeky enough to patent such an (unoriginal idea) and i am still amazed that they got away with it..
which probably explains why so many seem to have broken the patent.. it never occurred to them that such an unoriginal idea was under a patent.. it wouldnt to me..
but i am just a normal kinda dude.. who thinks in a normal kinda way not a member of the legal profession..
but as u say its all there.. my views are that in a vaguely sane world it shouldnt have been allowed to be all there.. the patent should never have been granted..
