Big Patent Law

I’m applying to law school at the moment and I see so many people saying if you want to work in big law you need to attend a T14. But when I look at large firms I see many different law schools represented (ASU,UCI, Baylor, Western). Is this advice correct in your experience? Did these people happen to get in prior to this recruiting guideline? Or, is there more wiggle room on law school prestige when you get into IP/patents?

To clarify: I’m not thinking you can go to a crappy law school and get a prestigious job but is attending a T40/50 shutting that career door? I’m hoping to be blessed with options with this admissions cycle, any advice would be helpful!

Thanks in advance!

In case you want more information about me, I have a BS, MS, and already passed the patent bar.
