Utility Models


Legal basis: in the absence of specifically defined terms in the legislation in respect of utility models, the provisions pertaining to patents shall apply, provided they are compatible with the subject of utility models. 

Notion of the invention: is considered to have been met if an invention is novel and has industrial applicability.

Novelty: is considered to subsist in an invention if the very information is not available to the public anywhere in the world. A disclosure may affect the registrability of a utility model if it is made prior to the filing of a utility model application in Turkey or the date of priority (if any) and comprises disclosure in respect of the initially filed context of a Turkish patent and/or utility model application with an earlier date of filing but published either later or the very day of filing of the application concerned. A disclosure non-affecting the registrability of a utility model is a disclosure made during a twelve-month term preceding the filing of a utility model application in Turkey or the date of priority (if any), and which is made either by the applicant or his predecessors.

Exceptions to protection: in addition to the “exceptions to patent protection“, utility model protection cannot be obtained for processes, products obtained by such processes, chemical or biological products, pharmaceutical products, and biotechnological inventions.
