Intellectual Property and Unfair Competition, law homework help

Patent law is exclusively federal in nature. A patent may be viewed as an agreement between an inventor and the federal government. Under that agreement, the inventor obtains the exclusive right (for a limited time) to exclude others from making, using, or selling his invention, in return for making the invention public by giving the government certain information about it.
