In short
A utility model is a document separate from a patent. Once its certificate is granted, the opposition route used for a patent does not open. The question of how a utility model is separated from a patent is read from the name of the document and from the door of opposition. Its protection is ten years from the filing date, and it cannot be extended. A patent is twenty years. That term cannot be extended either. Invalidity is sought from the court.
Post-grant opposition is the patent route
The post-grant opposition in Article 99 of Law No. 6769 is the route provided for a patent. The same opposition cannot be opened after a utility-model certificate has issued. How many days that opposition lasts is not written here. The day is read separately from the text of the statute. Obtaining the certificate does not turn an opposition petition into a claim for invalidity. A door that is open for a patent does not of itself stick to a utility-model certificate.
Which paper is in hand is understood from the name of the decision the Office wrote. An application form is not a certificate. A writing that stands still during the search is not the grant of a certificate either. The reader looks at whether the heading of the paper says patent or utility model. When the heading is mixed, the door of opposition is mixed as well. If a utility-model certificate has been granted, the post-grant opposition used for a patent is not opened in this file.
A report is not the grant of a certificate
Drawing up a report is not the grant of a certificate. The report shows the documents that were found. A utility-model certificate is a separate decision. The day the report issues does not start the ten-year term. The term runs from the filing date. The day the certificate is granted does not reset the counter. This distinction is the same for the twenty years of a patent. The years of the two documents are not written in place of each other.
Whether the report looks favourable or unfavourable is not itself the utility-model certificate. If there is no name of a decision, a certificate is not treated as granted. The petition does not make the day of the report the start date. Which certificate stands on the register is read from the name of the record in the file. If the record name is patent, the utility-model year is not written. If it is a utility model, the patent year is not written.
Invalidity stays in a separate file
Invalidation of a utility model is sought from the court. That claim is not a copy of an action for trademark invalidity. The reasoning used for patent invalidity is not pasted onto this page either. The two documents are two separate files. An action brought against a utility-model certificate does not of itself invalidate the text of a patent claim. An action brought against a patent certificate does not stand in for the utility-model certificate.
The city where the register is kept is not treated as the place of every action. The office being in Çankaya does not choose the court. Jurisdiction is read according to the defendant's residence and the dispute's own rule. The register being kept in Ankara does not carry every action to that province. The name of the district does not stand in for the type of document.
The city of the register does not carry the action
The register entry shows the type of document and the right holder. The name of the city is not the ground of a claim for invalidity. The office in Çankaya does not change the competent court. If an action is to be brought, the place is read from the file's own rule. The office address does not turn the ten-year term into the patent's twenty years either.
An opposition petition does not open the patent route after a utility-model certificate has been granted. Invalidity is sought from the court, in place of that door. The number of days is not in this text. The patent's twenty years are read from Article 101. The model's ten years are not a copy of that article. The year is not announced before the type is written.
If the heading of the paper is patent, the utility model's door of opposition is not sought. If it is a utility model, the patent's post-grant route is not sought. The year is not written before the heading is read. The day of the report is not put in place of the application. The claim for invalidity stays in court. The years of the two documents do not merge on a single calendar.
How the type of document is separated
The name of the document determines the door of opposition. The opposition used for a patent is not opened against a utility-model certificate. The two numbers of years are not written onto a single calendar either. A report is not a certificate. The city of the register does not carry every action.
Conclusion
A utility model lasts ten years and does not extend. After the certificate, an opposition under Article 99 cannot be opened. Invalidity is in the court. The patent's twenty years are the term of a separate document. The heading on term sits in the patent term article, the ground of invalidity in the patent invalidity article, and the question of use in the patent infringement article. The frame is on the intellectual property page. The basis is Article 101 of Law No. 6769, the Industrial Property Code. The year is not written while the type of document is mixed.
