Zed is a playwright. He wrote and produced an off-Broadway play about the life of Madam C.J. Walker titled, "Heat it Up to Straighten it Up," that closed after the third performance. Later that same year, on vacation in Atlanta, Zed went to see a new production called "Straighten It Up with Heat." Zed was appalled to discover that the play was substantially similar to his own. "Straighten It Up with Heat" becomes a big hit. What protections are available for Zed? What defenses are available against any claims Zed might make? Discuss it.
