Utility models are protected by a protection right. Grant of a protection right is certified through issuing a utility model a protection certificate. The fact of granting a utility model protection right is entered to the protection rights register. The substantive scope of a protection right is specified in protection claims contained in an utility model protection document. A protection right remains in force for ten years from the date of reporting the utility model to the Patent Office.
