Related rights (or intellectual property rights) is a term in copyright law. (Act on Copyright and Related Rights (Copyright Act)).
Related rights (or neighbouring rights) is a general term for a range of property rights. However, it has to be distinguished between copyrighted works (pursuant to § 2 Copyright Act) being the author’s own intellectual creations, whereas the purpose of related rights is to protect the legal interests of certain persons and legal entities who contribute to making works available to the public.

The law of related rights deems that the productions which result from the activities of such persons and entities merit legal protection in themselves, as they are related to the protection of works of authorship under copyright. Some laws make clear, however, that the exercise of related rights should leave intact, and in no way affect, the protection of copyright.
The duration of protection of related rights is less than 70 years. The protection of scientific editions (§ 70 Copyright Act), posthumous works (§ 71 Copyright Act) and protection of organisers (§ 81 Copyright Act) shall expire 25 years after the work was released. The protection of broadcasting organisation (§ 87 Copyright Act) shall expire 50 years after the first broadcast. The protection of performers (§§ 77 and 78 Copyright Act) shall expire 70 years after the death of the performer.
