Software maker 321 Studios, which until recently offered a way to make perfect copies DVDs, said it has appealed a pair of court rulings that bars it from selling its product.
Judges in California and New York have said the company"s software, which Hollywood studios have bitterly opposed, violates federal copyright law. In both appeals, the company contends that the copyright law is unconstitutional and that consumers have a right to make backup copies of DVDs or other materials they have legally purchased.
