Okay, okay. Let's not completely panic here. They have yet to say if they're going to use it at this point. However, they still have the patent on it which suggests they're thinking about it.

Basically, Sony new patent is for an "invention" where basically when you want to play a video game on a Sony console, the ID number of said game gets tied to your account/console. So, unless you sell your console with the game, this will effectively ruin the used game market. Now, Sony's patent does declare that you can have a small amount of uses on another console, but once you've reached a certain limit, the game is disabled until you play it on your original console.

Now, if you remember, Sony patented a similar technology all the way back in 2006, to no effect, so this could be nothing, but still, just a heads up in case they do decide finally go through with it.
