A frequent narrative I hear on HN is that going to court is ruinously expensive, emotionally taxing, wildly uncertain even if you're completely in the right, and so slow any victory is almost certain to be Pyrrhic.
Someone who believes that narrative would have expected this guy to lose, pay six figures in legal fees, have a mental breakdown, and the judgement to only come in five years after his magnet company closed down because they couldn't sell their only product.
Personally I don't have enough experience to know whether the US legal system really works that way.
