another case covering this area is "assessment technologies v. wiredata" (2003), in which the seventh circuit court of appeals ruled that a copyright holder in a compilation of public domain data cannot use that copyright to prevent others from using the underlying public domain data, but may only restrict the specific format of the compilation, if that format is itself sufficiently creative. "assessment technologies" also held that it is a fair use of a copyrighted work to reverse engineer that work in order to gain access to uncopyrightable facts. "assessment technologies" also created new law, stating that it is a copyright misuse and an abuse of process if one attempts to use a contract or license agreement based on one's copyright to protect uncopyrightable facts.
