I get your point, but in that case, I'd rather see it go to court and the patent get invalidated. While settling might be good for the settling parties, it doesn't stop patent troll from making more frivolous suites, and I don't think it is better for society as a whole.

Just to be clear I don't think settlements are always bad. But there are definitely cases (in both directions), where settlements result in a worse outcome for society.
