College Copy Shop (CCS) compiles, copies, and sells reading materials to students. The compilations are prepared on the instructions of professors, who indicate which parts of which publications should be included for their students. The copied materials include texts published by Deep Topics, Inc. CCS does not obtain the permission of Deep Topics, or any of the other original publishers of the copied materials, and does not pay royalties on the sales of the compilations. Deep Topics and others file a suit against CCS, alleging infringement of their intellectual property rights. Which type of intellectual property is involved in this situation? What is CCS’s likely defense? How is a court most likely to rule?
