I guess I'm wondering why you chose Cooley at all. Didn't you know its reputation and job placement stats ahead of time?
So, disclaimer, I don't have a clue, I'm just going to ramble.
IMHO, what it comes down to is whether you want to be a patent attorney or not.
If not, you're probably fine dropping out and becoming an agent. You might even have a shot at the USPTO examining corps in a bit, since CE is one of the few things they're chronically short of. In a few years, you could go back to law school elsewhere, either way.
If you do want that JD, you could go solo when (or if, given attrition rates there) you graduate. Another T4 would probably take you as a transfer no matter what (my understanding is that the private T4's are mostly out to collect tuition payments), although I think I read somewhere that Cooley can be snarky about releasing transcripts for students who try to transfer out. You can contact some of the other T4's in Michigan to see what they say, or for that matter WSU and MSU (T3's).
Moving up to a T2/T1, if you did well, who knows.
I don't think any firm would hire you as a tech spec after you got your JD. You'd either be hired as an associate or not at all, most likely the latter. I mean, how are they going to explain it to clients and to other people at the firm if you have a JD but aren't hired as an associate?
I've seen a few posts here in the last few years from T3/T4 grads who were unable to find any legal work after graduating, even before the economy got blatantly bad. In the current environment, even T1 grads are having a hard time.
I expect the economy to get much worse, also, but I was told Friday that I was wrong about things, so maybe I'm just a pessimist who is unable to see the economic miracle that Bernanke's Zimbabwean currency devaluation policies are creating. (Note: I freely admit that they may instead be Argentinean currency devaluation policies. I'm not sure which would be worse. Either way, we still end up broke and in chaos.)
