page 26  Article 116: The request shall comprise a petition for the grant of a certificate, the name of the applicant, the inventor and, as the case may be, the agent and the other required information relating to these persons and to the title of the utility model. In the event that the applicant is not the inventor, the request shall be accompanied by a statement justifying the applicant’s right to the certificate. Article 117: The description must disclose the utility model in a sufficiently clear and complete manner that a person skilled in the art and with average skill and know-how can carry it out. It must in particular indicate how the claimed utility model enhances the utility or functionality of the object. Article 118: The claims shall define the subject matter for which protection is sought. The description and the drawings may be used to interpret the claims. These must be clear, concise, and based entirely on the description. Drawings shall be provided when they are necessary for understanding the utility model. Article 119: The summary shall be used solely for providing technical information. It shall not be taken into consideration when assessing the scope of protection. Article 120: The applicant may withdraw the application at any moment while it is pending before the decision to grant the registration certificate for the utility model. Section 2. Unity of the invention, modification and division of the application Article 121: The application may only cover a single utility model or a group of utility models related to each other in such a way that they form a single general inventive concept. Article 122: The applicant may modify the application, but the modification must not go beyond the subject matter claimed in the initial application, until the time it is noted that the application meets the necessary conditions for the grant of the certificate. Article 123: The applicant may divide the application into several applications called divisional applications up until the time when the application meets the necessary conditions for the grant of the certificate. However, divisional applications may not go beyond the subject matter claimed in the initial application and must cover an inventive concept in its entirety. Each divisional application is supposed to bear the date of filing and, as the case may be, the date of priority of the initial application. Section 3. Priority claims
