This does not universally hold, though. For example, the "clean-room design" method of copying a work exists precisely to avoid potential copyright issues. One team reads the original work and writes a description in such a way that it cannot possibly be infringing, and a second team reads the description and creates the new work. This avoids any chance of someone reading the original work and incorporating potentially infringing aspects into the new work.
