Irrespective of the term of Turkish patent protection of 7 or 20 years, the State-of-the-Art (Standard) Search is to be conducted for patent applications in Turkey which otherwise shall be deemed to have been withdrawn  according to the Article 56 paragraph 4 of the Decree Law No. 551 pertaining to the protection of Turkish Utility Models and Turkish Patents in case, the request for (Standard) Search is not filed with the Turkish Patent Institute within 15 months from the date of filing of the application in Turkey or, from the date of the priority, if any, claimed in the application and, in case the (Standard) Search fee is not duly paid to the Turkish Patent Institute within the subsequent three months.
It is important to note that both of these deadlines cannot be extended in Turkey.

PCT applications entering into national phase in Turkey are not subject to this search procedure since International Search Reports are readily accepted by the Turkish Patent Institute.

As of the current sitation, the Turkish Patent Institute  has created an in-house searching unit to conduct State-of-the-Art Search only for some IPC codes. As for the IPC codes for which a Standard Search is not possible, the subject Search Report is to be established by one of the search authorities conducting search on behalf of the Turkish Patent Institute under special protocols. The list of said authorities is available DERİS’s web site  under INFORMATIVE DOCUMENTS/SEARCH EXAMINATION AUTHORITIES AND THEIR FEES 2010 together with the respective fees in Turkey The applicant is to select as of its preference the search authority, which is to conduct the search on behalf of the Turkish Patent Institute.
The fee for establishing the (Standard) Search Report requested by the selected search authority will have to be paid to Turkish Patent Institute as well as the handling fee of the Turkish Patent Institute simultaneously with the filing of the request for (Standard) Search, in order to simplify and accelerate the prosecution of the application.
However, if so wished, the fee for establishing the (Standard) Search Report can be paid within the three months subsequent to the filing of the request for conducting the (Standard) Search in accordance with Article 28, paragraph 1 of the Implementing Regulation of November 5, 1995.
It is important to note that this deadline cannot be extended in Turkey.
Turkish Patent Institute will settle directly with the selected search authority the search fee that said authority will be charging for conducting the search and establishing the State-of-the-Art (Standard) Search Report.

Yes, transitional Article 4, paragraph 2 of the Implementing Regulation which was amended on December 6, 1998, provides that "the (Standard) Search Reports established by the Search Authorities designated under the Patent Cooperation Treaty or Search Authorities conducting the search on behalf of the Turkish Patent Institute  under special protocols on the (corresponding) patent application(s), the priority of which has/have been claimed in the application filed in Turkey, will be accepted by Turkish Patent Institute for the prosecution of the Turkish application."
Namely, where any such (Standard) Search Report obtained from anyone of the PCT Search Authorities or Search Authorities working for the Turkish Patent Institute  exists, it will not be necessary to additionally refer the  patent application filed in Turkey to the State-of-the-Art Search. In other words, in case a corresponding search report established by the European, Russian, Chinese, Australian, Austrian, U.S., Spanish, Japanese, Swedish, Canadian, Finnish, Nordic or Korean Patent Offices for a corresponding patent application exists, they are accepted in Turkey under their capacity as International Search Authorities. Additionally, a corresponding search report established by the Danish Patent Office is also accepted under its capacity as a search authority, conducting search on behalf of the Turkish Patent Institute under special protocols.

It is necessary to file the request for (Standard) Search with the Turkish Patent Institute for a patent application in Turkey within the above referred period of 15 months by simultaneously submitting in the attachment thereof the copy of the (Standard) Search Report established by anyone of the above mentioned Search Authorities, on the corresponding priority application(s). 

In cases, where the (Standard) Search Report on the corresponding priority applications is not available at the date when the request for (Standard) Search comes up for filing within the above referred period of 15 months, such request will still have to be filed within the set time period of 15 months by indicating that the corresponding (Standard) Search Report is not available as yet and will be submitted at a later date upon its issuance, by the respective search Authority.
In cases, where the request for (Standard) Search is filed without the corresponding (Standard) Search Report, the respective fee will not have to be paid to Turkish Patent Institute simultaneously with the filing of the request for (Standard) Search, but when filing, at a later date, the (Standard) Search Report issued by the respective Search Authority. (Transitional Article 4, paragraph 3 of the Implementing Regulation of November 5, 1995).

No, the Turkish Patent Institute  does not accept corresponding search report for patent applications when there is no claim of priority. 

It is not mandatory to conduct a State-of-the-Art (Standard) Search for Utility Models applications in Turkey. According to Article 160 last paragraph of the Decree Law No. 551 pertaining to the protection of Turkish Utility Models and Turkish Patents, such (Standard) Search can be carried out upon request of the applicant or registrant of the utility model. 

The application is published after the elapsing of a period of 18 months from the date of filing of the application in Turkey or from the date of priority, if any, claimed in the application. The application is published in the official Turkish Patent Bulletin following the completion of the formal examination and subsequent to the filing of the request for the State-of-the-Art (Standard) Search (Article 55, paragraph 1). If not published earlier, the application is published together with the State-of-the-Art (Standard) Search Report according to Article 57, last paragraph of the Decree Law No. 551 pertaining to the protection of Turkish Utility Models and Turkish Patents No. 551

According to Article 59 of the Decree Law No. 551 pertaining to the protection of Turkish Utility Models and Turkish Patents No. 551 , the applicant for a patent disposes of 3 months from the notification to him of the State-of-the-Art (Standard) Search Report for deciding which of the types of patent with or without (substantive) examination he wishes to choose for the patent protection in Turkey. It is after the elapsing of this time period of 3 months during which the applicant is to determine the type of patent he wishes to choose, that the State-of-the-Art (Standard) Search Report is published in the Turkish Official Patent Bulletin wherein it is specified that the Turkish application concerns a patent with or without (substantive) examination. (Article 57, paragraphs 5 and 6). Where the applicant does not respond within this period of 3 months and determine the type of patent he wishes to choose, the Turkish patent application is considered and further prosecuted as a short term Turkish patent of 7 years without (substantive) examination. (Article 59 last sentence  of the Decree Law No. 551 pertaining to the protection of Turkish Utility Models and Turkish Patents). 

Applications entering into national phase in Turkey under PCT Chapter II are automatically prosecuted according to patent system with (substantive) examination whereas for applications entering into national phase in Turkey under PCT Chapter I, applicant has the option to choose either of the patent systems as indicated above. 

For the short-term protection of 7 years, after end of the opposition period, the applicant for a patent without (substantive) examination is free to take or not into consideration the observations/arguments put forward by the opponent(s). The applicant can respond to the objection/observation of the opponent(s) and, if he so wishes, can amend the claim(s) in consideration thereof within 3 months from the notification of the opposition. Where the applicant has not filed a response to the opposition/objection with or without amending the claim(s) within this period of 3 months, Turkish Patent Institute proceeds further by deciding to grant the "patent without (substantive) examination" for a term of 7 years from the date of filing of the application in Turkey. 

Yes, a "patent without (substantive) examination" of 7 years can be converted into a "patent with substantive examination" thereby extending the period of protection to 20 years provided that the request for substantive examination is filed within 7 years, at the latest, from the date of filing of the application in Turkey. Such request for (substantive) examination can be filed either by the patentee or by third persons. The examination fee is to be paid by the party namely the patentee or third persons having filed the said request for (substantive) examination (Article 60 paragraph 7). 

According to Article 62, paragraph 3 of the Decree Law No. 551 pertaining to the protection of Turkish Utility Models and Turkish Patents, in case, the applicant opts for a patent with (substantive) examination in Turkey, the request for substantive examination is to be filed and the Examination Fee is to be paid by the applicant within a period of 6 months following the publication in the Official Turkish Patent Bulletin of the State-of-the-Art (Standard) Search Report.
As the Turkish Patent Institute does not have an in-house examining unit, the examination of Turkish patent applications are conducted by foreign authorities on behalf of the Turkish Patent Institute under special protocols.
The fee for Substantive Examination varies according to the selected examination authority as shown in Deris’s web site under INFORMATIVE DOCUMENTS/SEARCH EXAMINATION AUTHORITIES AND THEIR FEES, 2007 and in addition to this, a handling fee of the T.P.I. is due. These fees are to be paid to Turkish Patent Institute at any time within the period of 6 months mentioned under point (7/9) according to Article 32 of the Implementing Regulation of November 5, 1995.
Turkish Patent Institute will settle directly with the selected Examination Authority, the fee such authority will charge for the substantive examination.

The Turkish Patent Institute notifies the results of the first examination to the applicant. In case this (substantive) examination report holds objections on patentability, the applicant is to file a response within the subsequent 6 months simultaneously with a request for second examination. In case the second examination also involves objections against the Turkish Patent application, The Turkish Patent Institute  notifies the applicant of its decision by recognizing him the possibility of a further reply within the subsequent 3 months in which period a third (final) examination should also be requested. The Turkish Patent Institute reaches its final decision in consideration of the third (final) examination report. It should be noted that the second or third examination fees are paid simultaneously with filing of the related request. The available second/third examination authorities and their fees as well as their special conditions can be found in Deris’s web site under INFORMATIVE DOCUMENTS/SEARCH EXAMINATION AUTHORITIES AND THEIR FEES, 2010. 

For patent applications entering into national phase in Turkey under PCT Chapter II, the International Preliminary Examination Report (IPER) is accepted as the first (substantive) examination report by the Turkish Patent Institute . Accordingly, in case this report recognizes patentability for the entire claim set, the application is immediately granted in Turkey On the other hand, in case there are any objections in IPER, second and third examination procedures are to be applied for the Turkish patent application.

Yes, following the publication of the Standard Search Report in the Official Turkish Patent Bulletin, third parties can raise opposition against the Turkish patent application within the subsequent 6 months. (Article 60, paragraph 1 and Article 62, paragraph 2 of the Decree Law No. 551 pertaining to the protection of Turkish Utility Models and Turkish Patents). 

Yes, the period of opposition is 3 months for  a Turkish utility model application following the publication of the application in the Official Turkish Patent Bulletin. (Article 161, paragraph 1 of the Decree Law No. 551 pertaining to the protection of Turkish Utility Models and Turkish Patents). 

According to Article 62, paragraph 2 of the Decree Law No. 551 pertaining to the protection of Turkish Utility Models and Turkish Patents, third persons can raise opposition against the patentability of the patent application within 6 months from the publication of the State-of-the-Art (Standard) Search Report.
The applicant disposes of 3 months, with a possible extension of 3 additional months, subsequent to the 6 months opposition period for responding to the opposition(s) notified immediately to him by Turkish Patent Institute according to Article 62, paragraph 4 of the Decree Law No. 551 pertaining to the protection of Turkish Utility Models and Turkish Patents
Turkish Patent Institute initiates the (substantive) examination after the elapsing of the period of response of the applicant (3 months + 3 months) as provided in Article 62, paragraph 4. According to Article 62, paragraph 5 of the Decree Law No. 551 pertaining to the protection of Turkish Utility Models and Turkish Patents, the fact that the applicant has not responded to the opposition(s) within the set period of response will not stop the initiation of the (substantive) examination.

According to Articles 70 and 71 of the Decree Law No. 551 pertaining to the protection of Turkish Utility Models and Turkish Patents, third persons may object before Turkish Patent Institute to the registration of the patent on grounds of formal deficiencies, in violation of the (formal) requirements as provided in Articles 42 to 63 of the Decree Law No. 551 pertaining to the protection of Turkish Utility Models and Turkish Patents (except for Article 45 concerning the unity of invention) and no deadline is provided in Article 70 of the Decree Law No. 551 pertaining to the protection of Turkish Utility Models and Turkish Patents for objecting to Turkish Patent Institute on such grounds.
However, according to the General Administrative Procedural Law, a deadline of 60 days should be applicable for objecting before Turkish Patent Institute against an administrative decision on the above grounds as the Turkish patent Decree-Law No. 551 contains no provision on the time period within which objections on such grounds are to be raised. There is no need to have opposed or filed objections against application during the opposition/observation proceedings for objecting before the Turkish Patent Institute against formal deficiencies according to Articles 70 and 71 of the Decree Law No. 551 pertaining to the protection of Turkish Utility Models and Turkish Patents.

According to Article 146, paragraphes 1 and 2  of the Decree Law No. 551 pertaining to the protection of Turkish Utility Models and Turkish Patents in all court actions (to be) instituted in accordance of the Decree-Law No. 551 and against all decisions of the Turkish Patent Institute  in implementing the provisions of the Decree-Law No. 551, the competent courts shall be the specialized courts in Turkey.
Both civil and criminal actions regarding Intellectual and Industrial property matters in Turkey are handled by the “Civil Court of Intellectual and Industrial Property and Criminal Court of Intellectual and Industrial Property” established as specialized courts. Said courts are presently only established in Istanbul, Ankara and İzmir.
Currently for the jurisdictions other than Istanbul, Ankara and İzmir, in the jurisdictions having more than one penal and/or civil court, according to the decision of the Supreme Council of Judges and Prosecutors, the 3rd Penal Court hears the penal actions for all Intellectual and Industrial Property matters whereas the civil actions are distributed amongst the 3rd Civil Courts of the jurisdiction.
The specialized court in Ankara is competent also for all actions to be instituted versus Turkish Patent Institute by third persons negatively affected or having suffered damage by the decisions of the Turkish Patent Institute

With the enactment of the package of new Industrial Property Legislation under various Decree-Laws, of which No. 551 concerns Patents and Utility Models in Turkey, Article 57 has been added to the Customs Act No. 4458 to permit, upon complaint, under the suspension of release procedure the seizure/withholding, by the customs, of goods infringing intellectual and/or industrial property rights, and among them patents and utility models under protection in Turkey. The withholding of the products is lifted and the customs formalities proceed further unless a court action for patent infringement is duly instituted or an interlocutory injunction is ordered by the court within 10 days from the date of the withholding of the products by the customs. 

- Filing certificate of use or importation documents
- Filing an offer for licensing
- Declaration of non-use

Please note for your information that in case of the production in Turkey of the patented product or of the product obtained via the patented process, it will be sufficient to meet the working requirement of a patent by filing the Certificate of Use with the Turkish Patent Institute  The said Certificate is to be executed and sealed by the Turkish Chamber of Commerce and Industry of which the firm using the subject patent in Turkey is a member or by any other relevant authority but only upon examination of the production premises in Turkey. The original form prepared in Turkish language has to be filed with the relevant Turkish Chamber of Commerce and Industry for certification purposes. In case the patent is put into use not by the patentee but by any other party in Turkey upon authorization/license of the patentee, the Certificate of Use shall be also accompanied with the deed of authorization/license and the same should be executed by both parties and sealed. It is important to note that the deed of authorization/license to use the patent shall additionally be recorded on Turkish Patent Register if it is to have effect against third parties of goof faith. 

The Turkish Patent Institute  effects the recordal of the importation documents as use of the patented product or of the product obtained via the patented process only upon receipt of sufficient documentation, which is constituted as follows:
Most importantly, a Customs Declaration for the goods imported by Turkish clients into Turkey obtained from the Turkish Customs Authorities evidencing the entry of the products/process embodying the patent into the Turkish territory is officially required. In the absence of the submission of this Customs Declaration, it is possible that the Turkish Patent Institute may not complete the recordal of the importation documents in the Turkish Patent Register.
The following documents can also be submitted together with the Customs Declaration- if any;
* A legible copy of an invoice from the patentee to the Turkish firm;
* Transportation certificate;
* Catalogue of the products;
* ATR1 certificate of origin and Customs Declaration from exporting party.
Said documents shall clearly indicate the exporting - importing parties as well as the patent subject to importation into Turkey. If the exportation is done by a company other than the patentee himself, a declaration of authorization prepared on the company paper of the patentee should be submitted before the Turkish Patent Institute In fact, this documentation establishes and attests the relationship between the patentee and the exporting company where the exportation is not effected by the patentee himself. 

Kindly be informed that you have to apply before the Turkish Patent Institute. for the publication of an offer for licensing, for the recordal of the Certificate of Use, of the importation documents, and of the Declaration of the Legal Excuse only one time for meeting the working requirement of a patented product and/or process. By following one of the above action, you comply with the use requirements for once and ever, thus these formalities are not required every year. 

It is to be noted that when an offer for licensing is withdrawn, the working requirements of the patent become once again due. Precisely, when the withdrawal of the offer for licensing is made, the patentee has to evidence the use of the patent by others means provided in the Turkish Patent Decree-Law no. 551, i.e. filing of the importation documents, effective use of the patent by filing the Certificate of use, etc. The patentee can withdraw, at any time, his offer for licensing provided that no person has demanded the patentee for the grant of a license (to use the invention). Withdrawal of the offer takes effect from the date of filing before the Turkish Patent Institute of the petition for the withdrawal of same. 

The minimal specific action a patentee would need to take in order to fulfill the working requirements is the filling of a request with the T.P.I. for the publication of an offer for licensing in the Official Turkish Patent Bulletin. In the absence of the prosecution of any course of action regarding the working requirements, it is to be noted that the patent cannot ex-officio revoked by the Turkish Patent Institute  on grounds of non-use or failing to meet the working requirement of a patented product and/or process. The Turkish patent is not abandoned or invalided due to the fact that no working requirement is met in the prescribed deadline of three years as from the publication date of the grant decision. The possible consequence of not fulfilling the working requirement either by filling a Certificate of Use in case of effective use and /or importation documents in case of importation of the patented product/process into Turkey, by filing a Legal Excuse for non-use or filing a request for the publication of an offer for licensing in case of non-use, would be a compulsory licensing which is however a procedure not actuated automatically by the T.P.I. but the license being granted by courts upon request of third parties. Please note that the risk of a compulsory license is very rare in Turkey. Until now, there is only one case for which the court has granted a compulsory license. 

A compulsory license can be requested in accordance with the Article 99 of the Decree-Law No. 551 pertaining to the protection of the patent and utility model in Turkey: “Compulsory license is (to be) granted where no offer for licensing has been made and where any one of the following situations/conditions materializes: Failure to put to use/work the patented invention in accordance with Article 96; Dependency of subject matter of patents as mentioned in Article 79. On grounds of public interest as mentioned in Article 103”.
For the request of a compulsory license by a third party, according to the Article 100 of same Decree-Law “any interested person may after the expiration of the period foreseen in Article 96, request the granting of a compulsory license on the grounds that the Turkish patent, at the time of the request, was not put to use or that the delay in the use thereof was not due to justifiable/legitimate reasons or that the use thereof had been suspended during an uninterrupted period of 3 years without justifiable/legitimate reason”.

The time period of three years ending within three year as from the publication date of the grant of the patent in the Official  Turkish Patent Bulletin cannot be extended.
On the other hand, after the expiration of the deadline, any application or submission of documents regarding the proof of the use of the patent can be submitted to and will be considered by the Turkish Patent Institute and recorded in the  Turkish Patent Register. However, the validity of these documents submitted after the expiration of the prescribed deadline, can only be determined by the court in a court action which may be instituted by third parties on the grounds of non - use of the Turkish patent within the 3 years period.

For filing of a Declaration of Legal Excuse, the T.P.I. requires the patentee to indicate the justifiable/legitimate reasons preventing him from putting the patented products/process in use in Turkey. The legitimate reasons of non-use of the Turkish patent can  be explained by the patentee himself in a declaration, which shall bear the name and the address of the patentee, the signature of a person authorized to sign on behalf of the patentee firm and needs to indicate absolutely the grant number of the patent, the title of the invention, the deadline of three years and mainly all the technical, economical and legal reasons of non-use of the patent. It is to be noted that according to Article 100 paragraph 2 of the Turkish Patent Decree-Law No. 551 on patents all such "technical, economical or legal reasons" of "objective nature" developing "beyond the control and will of the patentee" (like the patented product is still in development process and therefore not yet ready for the market, objective characteristics, compliance with standards/ authorization process, the need for new implementations in various fields) are deemed to be legitimate reasons for not working the Turkish patent.
It is also required by the Turkish Patent Institute to insert into the Declaration of Legal Excuse an approximate time period whereby the patentee indicates when he intends to start the commercialization of the patented product/process in the Turkish market. On the other hand, according to the recent practice of the Turkish Patent Institute, the reasons for the non-use of the patent can be declared to the Turkish Patent Institute simply in a petition without filing any declaration of legal excuse with the Turkish Patent Institute.
Such a Legal Excuse may be evidenced by supporting documents of non-use of the patent as ruled in amended Article 39 of the Implementing Regulation of 6 December 1998. Supporting documents can be copies of any official request filed with the regulatory authorities, to the ministry of health for obtaining a permission of marketing or any other documents without a confidential character evidencing that the patented product/process is still in clinical tests, experiences, etc.

Such documents are not published in the Official Turkish Patent Bulletin.    However in case a third party is interested with the subject matter of a patent, he can file a request with the Turkish Patent Institute by attending to the payment of a related fee and effect the examination of the file which may include such documents. In this way, we can conclude that these documents will be available to the public inspection.
