Bowers v. Baystate Technologies, 320 F.3d 1317 (Fed. Cir. 2003), was a U.S. Court of Appeals Federal Circuit case involving Harold L. Bowers (doing business as HLB Technology) and Baystate Technologies over patent infringement, copyright infringement, and breach of contract. In the case, the court found that Baystate had breached their contract by reverse engineering Bower's program, something expressly prohibited by a shrink wrap license that Baystate entered into upon purchasing a copy of Bower's software. This case is notable for establishing that license agreements can preempt fair use rights as well as expand the rights of copyright holders beyond those codified in US federal law.
