I found criminal law interesting but there's always a genuinely injured or dead person in the process. It's really depressing but I followed it for awhile until I stumbled into patents and copyright law. Like I said I just stick to the interesting and funny stuff. For instance, years ago Harley Davidson sued iirc Yamaha for having the "look and feel" of their exhaust system. Harley's made a legendary whump-whump sound. While Yamaha's made a high pitched whining sound. Yamaha then changed their engine design to sound more like a Harley and the lawsuits started flying don't know how it ended.

Here's a question for you the copyright on a work lasts till 70 years after a person's death. Now the world famous late mime Marcel Marceau copyrighted his act. Now since it's copyrighted does that mean that nobody can pretend to be locked in an invisible phone booth for the next 70 years? If I do pretend to be locked in a phone booth do I have to pay royalties to his estate if I do? If I pretend like I'm really locked in a portable-toilet or an elevator well I get sued for violating the "look and feel" of his act? Ah...Let the lawsuits begin.
