If you've left Big Law, you are already off the risk-averse path. These are very seniority-focused places, which will not hire you back after you've left the Big Law system (with the exception of a few high-prestige postings, like a court clerkship). i.e. these lawyers will probably never again work at Latham anyway.
Considering most lawyers in big law won't make partner (from what I've heard, what makes logical sense, and what this Quora post says[0]) most non-partner lawyers in big law will eventually leave. Let's keep them from becoming patent trolls, shall we?
