The utility model is a system which provides protection of the novelty, not only in Turkey but also all throughout the world and industrially applicable inventions. The procedures for the issuance of a utility model certificate are much more convenient than the patent certificates in terms of time and expenses. It has been considered that the simple and inexpensive procedural proceedings for utility models may encourage especially the small and medium scale enterprises (SMEs) and research institutions to make an invention and apply such inventions to the industry. Besides, particularly today, there exists a risk for the imitation of the inventions realised by the small and medium scale industrialists by the competitors in almost the same manner. Even if an invention is small and modest, the issuance of the utility model certificate for such an invention will serve as protection of the SMEs and their perpetuation economically.

Requirements for utility models;

  • Novelty – an invention is not patentable if the claimed subject matter was disclosed before the date of filing or date of priority if priority is claimed.
  • Industrial applicability -a patent can only be granted for an invention which is susceptible of industrial application.
