QFT. Just like anybody else that sues on a patent they actualy own (And we KNOW they where the originators of the idea) we would want our money too if somebody stole our idea. Just cause they are a big company dosent make them any different. Id have to say though, that the only 2 PSUs id buy from them are the X3 1000w and X2 550watt.A patents a patent and if they hold it they have every right to get damages. If the companies producing modular PSUs did not research enough and spend enough money on finding existing patents, thats just plain stupid. So what if they have waited, the offending companies shouldn't have done it (if there is a solid patent in place) in the first place.
You cant possibly say oh thats stupid, its what patents are for. Ultra have just as much right to enforce it as you do if you invent something.
