Qualifications
Are you sitting down? At a school desk? Well, get ready to do that for years and years to come. To become an IP lawyer, you'll need a lot of schooling—and you can't just coast by; you'll have to be a strong student. You need to start with a bachelor's degree, then take the LSAT (and do very well on it), get into law school, and graduate after three years with a Juris Doctor (J.D.) specializing in intellectual property or entertainment law.
Furthermore, you'll need to take and pass the state bar exam wherever you live in order to be able to practice law and eventually take on cases of your own. If you move, you'll have to take the bar exam again in whatever new state you choose to practice.
If you want to practice patent law, you'll need to have a bachelor's in a science- or engineering-related major (source) and then pass the USPTO exam.
In fact, the more you know about science, the better. You'll have a better chance finding work in patent law if you get a Ph.D. in chemistry, physics, or computer science before going to law school (source).
