Related rights is a term in copyright law, used in opposition to the term "authors' rights". The term neighbouring rights is exactly equivalent, and is a more literal translation of the original French droits voisins.[1] Related rights in civil law are rights which are similar to authors' rights but which are not connected with the actual author of the work. Both authors' rights and related rights are copyrights in the sense of English or U.S. law.

There is no single definition of related rights, which vary much more widely in scope between different countries than authors' rights. The rights of performers, phonogram producers and broadcasting organisations are certainly covered, and are internationally protected by the Rome Convention

В приведенных примерах "интеллектуальная собственность", но смежные права тоже яввляюися интеллектуальной собственностью. Я, главным образом, хочу показать, что "object", но не "subject". Мне кажется, что у аскера именно в этом трудность перевода.
