Patent law services play a critical role in protecting innovation and ensuring that inventors, startups, and multinational companies can secure and enforce their intellectual property rights. In an increasingly competitive global market, businesses must rely on experienced legal counsel to protect technological inventions, manage intellectual property portfolios, and prevent unauthorized use of patented technologies.
As a leading full-service law firm based in Istanbul, Legalixa Law Firm has provided comprehensive legal support in intellectual property law in Turkey since 1992. Our team of highly experienced Turkish patent attorneys and Istanbul patent lawyers assists domestic and international clients in protecting inventions through strategic patent application procedures, portfolio management, and enforcement strategies.
Turkey has developed a modern and robust legal framework governing intellectual property rights. Turkish patent law is primarily regulated under the Industrial Property Code No. 6769, which harmonizes the country’s patent system with international standards and European intellectual property regulations. The Turkish Patent and Trademark Office (TURKPATENT) serves as the central authority responsible for patent registration, examination, and administration of intellectual property rights.
Patent protection in Turkey offers innovators the exclusive right to exploit their inventions for a defined period, typically twenty years from the filing date of the patent application. This protection allows patent holders to prevent unauthorized manufacturing, use, sale, or importation of patented technologies.

Turkish patent law forms a vital component of the broader system of intellectual property law in Turkey. The current legal regime is largely aligned with European Union intellectual property directives and international treaties, including the Patent Cooperation Treaty (PCT) and the European Patent Convention (EPC).
Under Turkish patent law, inventions must meet three essential criteria to qualify for patent protection. These include novelty, inventive step, and industrial applicability. A patentability search is often conducted before filing a patent application to determine whether an invention meets these criteria and whether similar inventions already exist in prior art databases.
The legislative framework ensures that patent owners enjoy strong legal protection while maintaining a balanced system that supports technological innovation and economic growth. Patent protection also encourages foreign investment by ensuring that businesses operating in Turkey can safeguard their technological assets.
The role of experienced Turkish patent attorneys is particularly important during the patent prosecution process, as they ensure that patent applications comply with procedural and substantive requirements before TURKPATENT.

One of the most fundamental components of Patent Law Services involves assisting clients with filing a patent application before TURKPATENT. A properly prepared patent application must contain detailed technical descriptions, claims defining the scope of protection, drawings where necessary, and an abstract summarizing the invention.
Patent applications may be filed by individuals, corporations, or research institutions seeking to protect technological innovations. Once filed, the application undergoes a formal examination followed by a substantive examination to determine whether the invention meets patentability requirements.
Our Istanbul patent lawyers guide clients through each stage of the filing process, ensuring that applications are strategically drafted to maximize the scope of protection while minimizing the risk of objections from the patent office.
The patent registration process typically includes publication of the patent application, examination of the technical merits of the invention, and possible patent opposition proceedings initiated by third parties.
Following successful examination, TURKPATENT grants patent protection and records the patent in the national registry. Patent registration grants the patent owner exclusive rights over the invention for twenty years, provided that patent maintenance requirements are fulfilled.
Professional legal assistance is often essential during patent registration to address objections raised during examination and to respond effectively to opposition proceedings.





Patent protection in Turkey may be obtained through different procedural routes depending on the geographic scope of protection required by the inventor.
National patent applications are filed directly before TURKPATENT and provide protection exclusively within Turkey. This approach is often preferred by businesses focusing on domestic markets or seeking cost-efficient protection for inventions developed locally.
Our Turkish patent attorneys regularly assist clients with preparing national patent applications, conducting patentability searches, and managing the entire patent prosecution process.
Businesses operating internationally often require broader protection for their inventions. International patent applications allow inventors to seek patent protection simultaneously in multiple jurisdictions through a unified filing system.
One of the most common mechanisms is the PCT national phase entry process, which allows applicants to file a single international application before entering national phases in individual countries, including Turkey.
PCT national phase entry in Turkey requires compliance with specific deadlines and documentation requirements. Our team assists international clients in completing the transition from the international phase to the Turkish national phase before TURKPATENT.
Turkey is a member of the European Patent Convention, which allows inventors to obtain patent protection through European patent applications filed with the European Patent Office.
Once a European patent is granted, European patent validation in Turkey is required for the patent to take legal effect within the country. This process involves submitting translations and completing formalities before TURKPATENT.
European patent validation ensures that European patents are enforceable within Turkey and can be used to prevent unauthorized use of patented technologies in the Turkish market.
Companies that rely heavily on technological innovation often maintain multiple patents across different jurisdictions. Effective patent portfolio management is therefore essential to ensure that intellectual property assets remain valuable and enforceable.
Patent portfolio management includes monitoring patent deadlines, maintaining patent rights, evaluating licensing opportunities, and aligning intellectual property strategies with business objectives.
Our firm provides comprehensive patent portfolio management services for technology companies, research institutions, and multinational corporations seeking to optimize the value of their intellectual property assets.
Strategic portfolio management also involves identifying potential patent infringements, conducting patent due diligence during mergers and acquisitions, and ensuring that patent portfolios remain commercially viable.
Once a patent has been granted, patent owners must fulfill ongoing maintenance obligations to keep their rights in force.
Patent maintenance in Turkey requires payment of annual patent annuity fees beginning from the third year following the patent application date. Failure to pay the required patent annuity fees may result in the lapse of patent protection.
Our legal team assists clients with monitoring deadlines, ensuring timely payment of patent annuity fees, and maintaining patent rights throughout the lifetime of the patent.
Professional assistance in patent maintenance is particularly important for companies holding large patent portfolios, where missing deadlines may lead to loss of valuable intellectual property rights.

Patent ownership may be transferred through patent assignment agreements, mergers, acquisitions, or corporate restructuring.
A patent assignment involves transferring ownership of a patent from one entity to another. In Turkey, patent assignments must be recorded before TURKPATENT to become legally enforceable against third parties.
Our firm assists clients with drafting patent assignment agreements, conducting patent due diligence during transactions, and ensuring that ownership transfers are properly registered.
Patent due diligence plays a crucial role during corporate transactions, as it allows investors and acquiring companies to evaluate the strength, validity, and commercial value of a patent portfolio.
Patent protection would have limited value without effective enforcement mechanisms. Patent enforcement in Turkey allows patent owners to take legal action against parties that use patented technologies without authorization.
Patent enforcement strategies may involve civil litigation, customs enforcement measures, and administrative procedures.
Patent infringement occurs when a third party manufactures, uses, sells, or imports a patented invention without the consent of the patent owner.
When patent infringement occurs, patent owners may file patent litigation before specialized Intellectual and Industrial Property Courts in Turkey. Legal remedies may include injunctions, compensation for damages, and seizure of infringing goods.
Patent litigation requires careful legal strategy and technical expertise. Our Istanbul patent lawyers represent clients in complex patent litigation proceedings involving domestic and international technology disputes.
A patent preliminary injunction is an urgent legal measure designed to prevent ongoing infringement while litigation is pending.
Courts may grant preliminary injunctions when the patent owner demonstrates a strong likelihood of infringement and the risk of irreparable harm.
Patent preliminary injunction proceedings are often crucial in protecting market share and preventing further damage during patent disputes.
Patent opposition proceedings allow third parties to challenge the validity of a patent during specific stages of the registration process.
Opposition proceedings typically arise after publication of a patent application or following the grant of a patent. Competitors may argue that the invention lacks novelty, inventive step, or industrial applicability.
Experienced Turkish patent attorneys play an important role in defending patents against opposition challenges and ensuring that patent rights remain enforceable.
Even after a patent has been granted, its validity may be challenged through patent nullity proceedings or invalidation actions before Turkish courts.
Patent nullity proceedings may arise if the patent does not satisfy patentability criteria or if the invention was disclosed prior to the filing date. Courts may invalidate a patent entirely or partially depending on the circumstances.
Invalidation actions are complex legal proceedings requiring detailed technical analysis and legal expertise. Our firm regularly represents clients in patent nullity proceedings involving high-value technological inventions.
