U.S. Copyright Deposits Are Important

U.S. copyright applications must be accompanied by a deposit of “complete copies of the best edition.” Two recent cases underscore the importance of deposit copies. In Pyrotechnics Management v.

The fair use statute, 17 U.S.C. § 107, suggests certain types of uses that generally may qualify as fair use, and identifies four factors a court must consider to decide when any particular use qualifies.  The statute reads as follows: Notwithstanding the provisions of sections 106 […]
