I doubt they get much say over what goes into their employment contracts. Added to which, you assume all potential employees are savvy about these issues, which seems like a stretch. I can think of several techies who blank out at the mention of IP and wouldn't appreciate (or care less about) the consequences of such clauses. Particularly not when there's a lucrative dream job at a big firm at stake.

If you're going to name-and-shame anyone involved in filing a patent (and I'm still doubtful about what this would achieve, given all they're doing is maximising a flawed system), the lawyers would make more sense (you can find out who they are by examining the filings on the USPTO PAIR database), or the upper management who determines patent policy.
