Exercise 18

Two computer science majors, Trent and Xavier, have an idea for a new video game, which they propose to call "Hallowed." They form a business and begin developing their idea. Several months later, Trent and Xavier run into a problem with their design and consult a friend, Brad, who is an expert in designing computer source codes. After the software is completed but before Hallowed is marketed, a video game called Halo 2 is released for both the Xbox and the Playstation systems. Halo 2 uses source codes similar to those of Hallowed and imitates Hallowed's overall look and feel, although not all the features are alike. Using the information presented in the chapter, answer the following questions.
Based only on the facts described above, could Trent and Xavier sue the makers of Halo 2 for copyright infringement? Why or why not?
