If I want to sue someone for my (alleged) patents, why not make me pay the legal costs for both sides, as the case goes to court (not after), until the case is decided one way or the other? that way, if a big fat ass company sues a small guy, the small guy can at least try to fight in court. May be he'll lose, but he'll at least have a chance to fight - it'll also make these big guys think a bit before suing for patents?
