A few things. (my credentials, so you'll listen: PhD bio, graduating T14 3L, going to V100 patent firm)
1.) You absolutely must finish your Ph.D.
You probably don't want to hear this, but it's true. If you were in mechanical/electrical engineering, maybe not...and your physics background might help a little, but the overall pretty hard and fast rule is that biotech patent work generally requires a Ph.D. at this point. I am sure others will chime in and say that this isn't true, that they know people with just bio bachelors that do patents, "look, heres a partner with only a B.S.", etc. You want to gamble away a quarter million bucks on that working out for you? Be my guest. I know for a fact that I would not have the job I have now without "Dr." in front of my name, period, and my UG GPA was much, much higher.
2.) You must KILL the LSAT.
I mean slaughter it. I mean 174 and up. Your GPA is a HUGE burden on your application right now. The only way to get a school to care about you is to dangle a very, very high test score in front of them. You have some things going for you: 1)You've made a 160 cold. I made a 165 cold and made it into the 170s with minimal additional prep. If you take a full on prep course and devote yourself to it, you've got a good shot. 2)Fewer people are taking the LSAT now than anytime in the last 4-5 years. It may well be easier for you to make a higher curved score than it was back then.
3.) You must plan your career very carefully.
It is important for IP people to have much more of a "plan" for their careers than other students in order to take full advantage. You need to be thinking about what city you want to practice in. In all honesty, the correct answer to that is probably going to be one of NY, DC, Boston, and San Diego. There is IP work in Chicago and in the Bay Area as well but those markets are extremely competitive. If, for some reason, you fall short on the LSAT and cannot be convinced to stay away from law school (which you should), the next option is to go to the best school you can get into in one of those cities and immediately start hustling your ass off from the first day you step on campus. Go to local bar meetings. Go out to lunch with partners in local firms, or associates, particularly if you went to their school. There are numerous other threads here about how to hustle.
You may also want to consider getting the patent bar out of the way relatively early as well. That will show firms at OCI or at patent fairs that you are a serious candidate. I'll be honest - plant bio is a niche in this field from what I have seen, and a pretty small one. Biotech work is in a lull right now while Congress and the courts figure out gene patents, biosimilars, genomics, etc.
