Database rights last for fifteen years from the end of the year that the database was made available to the public, or from the end of the year of completion for private databases (Art. 10). Any substantial change which could be considered to be a substantial new investment will lead to a new term of database rights, which could, in principle, be perpetual. Database rights are independent of any copyright in the database, and the two could, in principle, be held by different people (especially in jurisdictions which prohibit the corporate ownership of copyright): as such, database rights can be compared to the rights of phonogram and film producers.
