Prof. Patry discusses a recent 6th Circuit Case,  ATC Distribution Group, Inc. v. Whatever It Takes Transmissions & Parts, Inc., 402 F.3d 700 (6th Cir. 2005), and in so doing, takes to task a prior decision,  American Dental Association v. Delta Dental Plans Association, 126 F.3d 977 (7th Cir. 1997), for its analysis as to what is a taxonomy, what is a code, and what is a copyrightable compilation.
