Australian trade mark law

Australian trade mark law is based on common-law use-based rights as well as the Trade Marks Act 1995 (Cth), which is administered by IP Australia, an Australian government agency within the Department of Industry, Science and Resources. Use-based rights are less certain than registration, and depend on the mark having developed a reputation in the region in which a business owner seeks to enforce its common-law trade mark.
