As I understand it they thought there was a chance Nvidia would settle, since the lawyers worked on contingency instead of telling him not to waste his time

By this guy's account, his attorneys sent and responded to a number of letters and arranged for a meeting with NVIDIA counsel. So you have to put it in context: this didn't demand a whole lot of time and effort, and they never actually filed a lawsuit.

From the looks of it, this firm primarily works on contingency, so it's not like they were doing anything out of the ordinary. They took a flyer on his "case" on the off chance that some correspondence might lead NVIDIA to throw a few bucks at this guy.
