Universal Copyright Convention
Universal Copyright Convention [UCC]: Signed in 1952 and revised in 1971, this treaty enabled the United States and other Pan-American countries that had copyright registries and marking requirements to join with Berne countries in an international treaty. Less demanding than Berne, it allowed a marking like "© David Vaver 2000" to satisfy any formalities a state required as a prerequisite of copyright. Canada adheres to the UCCs 1952 version. The UCC is less important today because most states, including the United States, have since joined Berne, and TRIPS also mandates compliance with Berne's higher obligations and "no-formalities" rules.
