Antitrust law might not sound as sexy as space law but it might be very attractive to many of you. Antitrust law is the law of competition.

A lot of law students get disappointed by how formalistic legal reasoning can be. For example, in patent law, to figure out if something can be patented you have to decide if it’s, say, a “process” but not an “abstract idea,” but if it is “it adds significantly more to the abstract idea.”
