The connections and what you will learn outweigh working for a judge in my view. This is what you want to practice, if it was just some internship doing anything that would be different. But the connections you make now may help you land a paid position in that field later on, these people in IP know other people in IP. If this is what you want to practice, take the internship, make connections, get experience and parley that into something for 2L or when you graduate.
