Sui generis
A similar case that led to the use of the label "sui generis" is the relationship of New Caledonia relative to France, because the legal status of New Caledonia can aptly be said to lie somewhere between a French overseas collectivity and a sovereign nation. Although other examples of such status for other dependent or disputed territories may exist, this arrangement is unique within the French realm.
Related rights
Within the European Union, the rights of film producers (as opposed to directors) and database creators are also protected by related rights, and the term is sometimes extended to include the "sui generis" rights in semiconductor topologies and other industrial design rights. A practical definition is that related rights are copyright-type rights that are not covered by the Berne Convention.
