I agree for the most part with bigs, but as far as I know, Santa Clara actually moved up in the rankings and was ranked lower last year. (It wasn't 74 in 2010, it was in the 90's). That's besides the point and doesn't really matter. As many people have said before me, I think that outside the top 14 law schools, region is incredibly important. I can't speak of the IP market in Houston, but I can speak a bit as a 2L law student in the bay area. There are internships available, and I had like 4 or 5 interviews as a 2L. I just don't know how much sense it makes for someone to transfer down in the rankings (for instance, out of Miami). I can honestly say I've never heard of anyone doing it. Not saying it's the wrong move, but it's certainly unusual. Your best bet may be to speak with IP attorneys in the area of your current school and see what they think. If you honestly believe you will have little to no shot at finding a job in IP law upon graduation, maybe consider a change. Past "good markets" for IP law (from what I've been told) include, but are not limited to DC, NY, the bay area, and Chicago. If you have specific questions about schools in the bay area or job hunting in the bay area, feel free to pm me. I am still a student, but I've had a bit of experience job hunting here.
*EDIT* just out of curiosity, I checked Santa Clara's passed rankings. 85 - 2009, 93-2010, 84 - 2011. Bigs is right that outside tier 1, rankings fluctuate quite a bit. For instance, Villanova, a past highly ranked t2 dropped nearly 20 spots this year. Just interesting to note.
