Corrupted until it's unrecognizable
The whole point of patents is to improve the state of the arts. The body of patents should be the first thing that practicioners go to to find resuable solutions to hard problems. Instead, the current regime encourages patents to be ignored and to be written in such a way that they are worthless. Patents are supposed to be documentation for other engineers like peer reviewed journals or text books.
Of course they are nothing of the sort anymore. They have been corrupted to the point where they are completely unrecognizable.
