In my Marketing class, I do a project where students work in groups to "create" a company and a product new to the market that they have to "sell" to the school.  The companies have to create an original logo.  In creating their logos, I'd have students check the USPTO database to be sure their logo ideas don't match ones already registered in the database.  Also, I would get students to use the patent classification system to give their new products a unique name using patent "language".
