> PATENT SYSTEM > UTILITY MODEL PROTECTION IN KOREA The utility model system is characterized by simple and quick registration of rights and a short protection period (10 years). The utility model system protects such inventions that relate to the shape or structure of devices. The filing procedures for registering a utility model are practically the same as those for a patent. Utility model applications, however, require one or more drawings to be attached, as utility model protection is directed toward devices. Under the Utility Model Act revised in 1999, utility models are registered without technical examination in order to promote the R&D function of small and medium-sized enterprises. A utility model application that meets formality requirements is registered without examination. If a utility model owner wishes to enforce utility model rights against an unauthorized third party infringement, he or she must request a technical examination of the registered model, and obtain an Examiner's Decision to maintain the model rights. Thereafter those rights are enforceable against the infringing third party. An invention that is claimed in a patent application can be granted utility model registration through a dual application system. Likewise, a device that is claimed in a registered utility model or a utility model application can be patented as far as it is eligible for a patent. This allows applicants to obtain utility model rights as early as possible and exercise their rights for a longer period of time under the patent system. The term of a registered utility model ends 10 years after its filing date.
