Sui generis
In sociology, the "sui generis" is what has been externalized, then internalized in the overall public and becomes a part of society that simply exists in its construct. It is not something that is not thought to have been created, because it is imbedded in everyone's way of thinking and being. Instances include the idea of love, or going to school, or clothing belonging to a specific gender. These examples are "sui generis" for they simply exist in society and are widely accepted without thoughts of where they come from or how they were created.
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.
