Based only on the sentence and not on history (because I don't know) he could have been the plaintiff and not the defendant. He was involved - we don't know that he was the one being sued, on that sentence alone.

Grammar Geekhe could have been the plaintiff

True. I hadn't thought of that. I don't know the history either. So it should be "Nobel accused someone of or was accused of violating patent law".
