I don't know how it is in the States, but here in Germany a patent holder suing in court is always presumed right until the defendant can prove his innocence (if he can). There is no presumption of innocence in patent cases. It's called "reversed burden of proof" or something. The allegation of the patent holder is enough to make a party guilty until proven otherwise. I'm sure it must be similar in the US.
