This is a semantic and autistic post, but I'ma sperg out for a second because the terminology that's being used is triggering me:
Frank Wu is not a "patent troll." Patent trolls are guys or companies who claim to have a patent, but just sit on the technology and don't practice it. The term doesn't refer to the lawyers the trolls hire to represent them.
More importantly, Frank (as far as I can tell) is a patent agent, not a patent lawyer. This means he doesn't have a JD, hasn't passed the bar, isn't a lawyer, and spends his time drafting patent applications and providing technical know-how assistance. He probably isn't involved in any litigation or arguing cases or any of the activities that we would associate with patent trolling. The most you could say is that he possibly works alongside people who represent patent trolls, but calling him a patent troll is actually overstating the kind of work he does.
(not hating on patent agents, one of the sharpest guys I know works as one)
