I have heard horror stories about Big Law, and at 47 yrs old I am not really interested in becoming a senior associate/slave doing what I am doing in my present firm, but this Big Law firm does a lot broader range of work, including litigation. I'm not going to take any work with me, so I wouldn't be a partner.
My long term goal is to go back in-house, but it might be beneficial to put in a few years in a top ranked firm, first. My present firm is quite small, very focused on one aspect of patent law, and quite honestly has sort of a cheesy name (the owner did not use his own name - FL allows firms to use names like "The Ticket Clinic, PA" which is not our name, but is almost as bad imo).
I've never worked at Big Law, I grew up in-house (18 yrs) and have worked the last 4 in this small firm. But I am ready to do something else/more.
