<p>I agree with Concerneddad that one does not NEED a graduate degree in a science to be able to practice patent law, and also that, unfortunately, employers can hire new patent lawyers with advanced degrees, so they do so in preference to those having only a bachelor’s degree.</p>
<p>As far as non-scientific undergraduate courses, the only one I would specifically recommend would be a course in general business law, to give you an idea of legal thinking and a little of the basics that you may encounter if you wind up working for a corporate employer. Other than that (and even that’s not necessary), take whatever interests you and that you can do well in to get your GPA up there (otherwise you might not even get into a law school).</p>
