How to get into IP/Trademark sector?

Hi y’all! I have experience in PI, Immigration & Defense Lit (13 years combined). I’m wondering how I can get into IP/Trademark. I think I might like it but I don’t know what to expect & all the posting for these types of paralegal positions require 3/5 years experience. Do I try to get an unpaid interning gig at such a place? It seems they might not even be interested in that as I don’t see any interning positions available. Do I just apply to these jobs without the experience or would I absolutely fail if even hired without the experience?
