Yes, the patented inventions should be put into use in Turkey.
The period for using or working a patented invention is three years as from the publication of the patent grant in the Turkish Patent Bulletin (from the date of the publication of the decision to grant in the European Patent Bulletin in the case of European patent) or four years as from the application date of the patent, whichever is the later. This period is especially important in respect of the compulsory requests, as it is not possible for third parties to request compulsory license before the expiration of this statuary period.
The due date for use is actually relative since the actual due date for use is calculated considering the date of request for a compulsory license. In other words, the use can be performed any time during the lifetime of the patent but should be performed before the request for compulsory licence for avoiding any risk of compulsory license if three years period have already passed. For instance, if the use has been performed at a time after 3 years as from the publication of the patent grant in the Patent Bulletin but before the date when the request for compulsory license is filed, the use requirement has been deemed to performed.

If the patented invention is not put into use or not used as required, it will not cause to any loss of patent right but the patent will be vulnerable to compulsory license.
The third parties can ask compulsory license on the basis of one of the followings;
In case of request for compulsory license, the authorized court will notify the patentee of such request and ask observations/opinion of the patentee within one month as from the date of notification.
In assessing the use, market conditions and circumstances beyond the control and will of the patentee is taken into consideration. Technical or economic or legal reasons of an objective nature, such as marketing authorization, compliance with standards, need for new applications to be made in different fields are to be deemed to constitute legitimate excuses for the inability to put the patent to use. These reasons in the nature of constituting obstacles for using the patented invention are accepted as reasons beyond the control and will of the patentee.
Non-use or use declarations, as prescribed by the Implement Regulation (Rule 117 (7)) but not the Law, should be filed within three years as from publication of the decision to grant patent in the Turkish Patent Bulletin (from the date of the publication of the decision to grant in the European Patent Bulletin in the case of European patent) or four years as from patent application date, whichever is the later. The use and non-use declarations filed for the patents are published in the Turkish Official Patent Bulletin.

The Implementing Regulation, in general terms, specifies that the market conditions and circumstances beyond the control and will of the patentee is considered in assessing the use. Technical or economic or legal reasons of an objective nature, such as marketing authorization, compliance with standards, need for new applications to be made in different fields are to be deemed to constitute legitimate excuses for the inability to put the patent to use.

The Regulation does not prescribe any positive or negative effect on patent rights if use or non-use declaration is not filed within the prescribed due dates.

As for the nature of the declarations, a simple declaration of use or non-use is sufficient. The declarations can only be submitted to the Turkish Patent and Trademark Office electronically as signed by the rights owners or the Turkish patent attorneys in the registry of the patents. In the case of the foreign entities located abroad, the declarations can only be submitted by the patent attorneys in the registry.
In the case of use, no evidence of use is required; therefore, simple declarations are enough to perform the requirement of declaration of use. In any event, it is recommended that the rights owners keep the evidence of use in their records against possible requests from third parties to substantially prove the use when there is any contention for compulsory license in the future.
The declaration in respect of the use or non-use of the patent is published in the Turkish Patent Bulletin. The patent in respect of which their being used has not been declared within the prescribed time limit is also published in the Turkish Patent Bulletin.
Not actually, they are quite rare in the Turkish jurisdiction.
