Patent Law: Purpose, Function, and Place within Industrial Property Law
Patent law is the most important legal basis for technological development, determining the competitive strength of modern economies. As a sub-branch of industrial property law, patent law is more than simply obtaining a “written document”; it is the mechanism that establishes the delicate balance between protecting inventions, which are products of human intelligence, and making these inventions available for the benefit of society.
The Basic Philosophy of Industrial Property Law
Industrial property law is a branch of law that brings together elements such as trademarks, patents, designs, and geographical indications, and safeguards creativity in commercial life. The main purpose of this field is to encourage creative activities and prevent the unfair copying of products resulting from these activities.
The patent is the most “heavily” and “technically” protective tool in this system. The basic function of a patent is based on the principle of “making knowledge public” in exchange for “rewarding the monopoly”. When an inventor obtains a patent for the technology they have invented, they register their invention with the state. In return, the state grants the inventor a complete monopoly right over the invention for a certain period (usually 20 years). In exchange for this protection, the inventor discloses the details of their invention to the public. Thus, society gains access to information about that technology, and when the patent period expires, that technology becomes a “public good” that everyone can use. The Purpose of a Patent: The Engine of Innovation
The social and economic functions of a patent can be summarized under three headings:
Encouraging Innovation: Inventing something requires significant time, capital, and R&D effort. If a company or individual knew that their invention could be copied by competitors the next day and sold cheaper, they would not invest in new technologies. A patent encourages inventors by providing the assurance that “the investment will be protected.” 2. Facilitating Knowledge Transfer: When a patent application is filed, the technical details of the invention are published in a way that everyone can read. In this way, even if another inventor cannot copy that invention, they can be inspired by the technical information there and create a “better” or “different” one. This allows science to progress cumulatively.
Creating Economic Value: A patented invention is not just an idea; it is also a commercial asset. Patents can be transferred, sold, or licensed (leased) to generate income. This increases the value of companies and directly contributes to the economy.
The Place of Patents in Industrial Property Law
Unlike intellectual property law (copyrights), a patent protects not the “expression of the idea,” but the “technical solution itself.” For example, while the writing of a book is protected by copyright, the working mechanism of the typewriter on which that book was written (if it contains a new solution) is protected by a patent.
The Industrial Property Law (IPL) system is our fundamental legislation regulating all processes in this field. Patent law is the pinnacle of this system; because while a trademark deals with the “name” of a product, a patent deals with “how it works” or “what it is used for.” Therefore, obtaining patent protection is a much more challenging process than trademark registration, requiring technical examinations and stricter legal oversight.
Balancing Public Interest and Private Property
The most debated issue in patent law is how to balance private property (the inventor’s right) and public interest (society’s access to technology at an affordable cost). If patent protection is too long or too strict, access to technology becomes difficult and societal progress slows down. If there is no protection at all, no one will spend time inventing something new.
The Industrial Property Law No. 6769 establishes this balance with a limited period of 20 years. While this period is considered a reasonable timeframe for the inventor to recoup their investment and make a profit, the fact that the invention is made available for common use by society at the end of this period continuously advances humanity’s technological accumulation.
In short, patent law is not just an arena where large companies wage legal battles against each other; it is actually a mutual “trust and reward” system designed to improve humanity’s science, technology, and quality of life. The inventor is assured that their labor will not be stolen; Society also prepares for the next big step by learning how that invention works.
Patent in the Industrial Property Law No. 6769 (IPL) System
For an invention to be protected by a patent, it is not enough for it to be “new”. The Industrial Property Law No. 6769 (IPL) has established a very strict and technical “filter” mechanism for patent protection. This mechanism is designed to prevent the unnecessarily monopolizing the technical knowledge of society and to reward truly qualified inventions.
Patentability Criteria: The “Holy Trinity”
For an invention to be patentable, it must meet three basic conditions simultaneously. If even one of these conditions is missing, the patent application will be rejected:
A. Novelty
The invention must not have been accessible anywhere else in the world (in writing, orally, or through use) before the application date.This is called “the prior art.” If a mechanism you invent has previously been published as an article in a journal, exhibited at a fair, or sold in another country, it is no longer “new.” The novelty criterion is “absolute”; that is, existing anywhere in the world, not just in Türkiye, prevents patenting.
B. Inventive Step
The invention must not have been obviously derived from the existing technical state by a person who is an expert in the field. To give a simple example; simply changing the color of a part or using a higher quality material does not count as an inventive step. The invention must “surprise” an expert in the field and go beyond an expected development. This criterion requires a “creative leap of an idea.” C. Industrial Applicability
The invention must be able to be produced or used in any branch of industry, including agriculture. Inventions that are theoretical or imaginary, do not physically work, or cannot be mass-produced in industry—”impossible”—cannot be patented. 2. What Cannot Be Patented?
The Turkish Patent and Trademark Office (SPK) has excluded certain subjects from patent protection in the name of public interest, ethical values, and the advancement of science:
Non-Inventive: Discoveries, scientific theories, and mathematical methods (Finding something that already exists in nature is not invention).
Mental Activities: Rules of games or simply methods of conducting business.
Aesthetic Creations: Literary and artistic works (these are covered by copyright).
Contrary to Public Order: Inventions that are contrary to morality or public order (e.g., methods of human cloning).
Biological Processes: Completely biological processes used for the breeding of plants or animals that do not involve human intervention.
Types of Patents: Patent and Utility Model
The SPK system offers two main protection tools:
Examined Patent (20 years): This is the strongest protection. The novelty of the invention and the presence of an inventive step are confirmed by a detailed examination by the Turkish Patent and Trademark Office. 2. Utility Model (10 years): Also known as a “small patent”. The inventive step (creativity) requirement is not sought; only novelty and industrial applicability are sufficient. It is less costly and faster; it is especially preferred for simpler mechanical improvements.
Prior Art and Proof
The inventor applying for a patent must describe the technical details (description) of their invention so clearly and adequately that an expert in the field can realize the invention upon reading the document. If the description is incomplete or misleading, the patent will not be granted. This system is the purest form of the “Monopoly in Exchange for Information” principle. The inventor must reveal their secret so that technology can advance.
Patentability is a legal assessment independent of the commercial success of a product or method. A product may sell very well in the market but may not be patentable because it lacks an inventive step. Or a very complex invention may be used by very few people but can be protected by a high-level patent because it meets all the criteria. Thanks to these filters, the patent system becomes not “a place where all kinds of ideas are registered,” but “a platform where those who contribute to humanity’s technological treasure are honored.” Law No. 6769 aims to both protect the inventor and defend society against the “patenting and closure” of already existing knowledge by others while applying these criteria. Protection of Patent Rights
Protecting patent rights is a highly technical and legally demanding process that begins with the application and is finalized with registration. According to the Industrial Property Law No. 6769, patent rights are created with “registration.” In other words, having made an invention does not grant patent rights to that invention; a proper application must be made to the Turkish Patent and Trademark Office (TÜRKPATENT) and this application must successfully pass the examinations. 1. Application Process and Examination Stages
The patent acquisition process is similar to a selection process. The process basically works as follows:
Application: The inventor submits a file to the institution consisting of a “description” (what the invention is), “claims” (the features they want to protect), and an “abstract”.
Formal Examination: The institution checks whether the file is complete.
Search: The institution searches patent databases all over the world. A “Search Report” is prepared on whether the applied-for invention is “new”.
Publication: The application (unless there is a specific request) is published in a bulletin after 18 months. This allows third parties to become aware of the invention and gives them the right to object. * Examination: The inventor requests an examination based on the search report. Institution experts thoroughly examine whether the invention has an “inventive step”.
Absolute Rights Provided by a Patent
After a patent is registered, the inventor (patent holder) is granted very strong “absolute” rights. These rights mean having a commercial monopoly on the invention. The patent holder may prohibit the following actions by third parties without their permission:
Production: Producing the product covered by the invention oneself or having it produced by another. * Sales and Marketing: Marketing the patented product.To manufacture, sell, or import.
Use: If the invention is a method, to produce using this method.
These rights come into play in case of “unauthorized use by third parties”. The patent holder can protect their rights by filing lawsuits for “cessation of infringement”, “remedy of infringement”, or “compensation” as soon as they detect unauthorized use.
Protection Periods and Continuity
Examined Patent: Protected for 20 years from the application date. This period cannot be transferred or extended. At the end of 20 years, the invention becomes public domain (everyone can use it freely).
Utility Model: Protected for 10 years. * Annual Fees: In order for the patent to be protected, “annual fees” must be paid to the institution every year. If the fee is not paid, the patent right automatically expires. This is a “cleaning” mechanism of the system; it removes the legal burden on inventions that have no economic value or have been abandoned. 4. Exceptions and the Risk of “Non-Use”
Although patent rights are absolute, they have some limitations:
Private and Non-Commercial Use: A person using a patented technology at home for their own private research or curiosity does not infringe on patent rights. * Compulsory Licensing: If a patent holder does not commercialize or market their invention and prevents the public from benefiting from that technology (or if there is a vital situation in terms of public health/safety), the state may grant a “compulsory license” allowing third parties to produce that technology. This prevents the patent from becoming a “trap” that is contrary to the public interest.
Limits of Protection: “The Principle of Territoriality”
One of the most critical points is that patent rights are “territorial”. A patent obtained from Türkiye provides protection only within the borders of Turkey. If you want your invention to be protected in Germany or the USA, you must also apply in those countries. This reveals the necessity of “international cooperation” which is fundamental to international trade and the patent system. Protecting a patent is not just about acquiring a piece of paper, but about surrounding the technical power behind that paper with a legal shield. A patent holder gains bargaining power against competitors, generates income by licensing their technology, and protects their market share thanks to this registered right. However, all these processes are possible with disciplined management, such as the complete preparation of the file and the timely payment of annual fees.
Non-Patentable Subjects, Rights, Registration and Priority Rights
Patent law is a field with clearly defined boundaries to reward creativity while simultaneously protecting social life, public health, and the general progress of science. In this final section, we will consider the “red lines” of the patent system, the legal nature of ownership, and “priority rights,” an international application strategy, as a whole. 1. Non-Patentable Subjects and Inventions
The Industrial Property Law does not allow every idea or every technical development to be patented. Subjects that cannot be patented have been determined by considering the common interests of society:
Discoveries and Theories: Finding a previously unknown phenomenon in nature (e.g., a new element) is a “discovery,” not an “invention,” and cannot be patented. Similarly, scientific theories and mathematical methods are also included in this scope because they are abstract. * Aesthetic Creations and Mental Activities: Mental processes such as literary works, music, or even just a rule of a game are subject to copyright protection, not patent protection. * Public Order and General Morality: Patents cannot be granted for inventions that are contrary to human dignity, disrupt public order, or are contrary to moral values (e.g., human cloning methods or processes that directly use the human body). * Biological Processes: Plant and animal production processes that do not involve human intervention and occur entirely through natural means cannot be patented. * Surgical and Diagnostic Methods: Surgical and treatment methods applied to the human or animal body are outside the scope of patent protection due to medical ethics (however, the devices and drugs used in these methods can be patented).
Rights Arising from Invention and the Nature of Registration
Invention is a moral right that forms the basis of patent law. Registration is the legal process that “monopolizes” this right. * Moral Right (Inventor’s Right): The person who makes the invention has the right to request that their name be stated as the “inventor” in the patent. This right is non-transferable; even if a company owns the patent, it is mandatory to state the name of the real person who made the invention. * The “Constitutive” Nature of Registration: The patent right arises with the registration of the patent (Constitutive registration). Before registration, the inventor cannot fully benefit from the “absolute” protection provided by the Industrial Property Law. Registration is the legal basis for saying to the state, “I am the owner of this invention and I have a monopoly right over this technology.” * Protection Provided by Registration: Registration grants the patent holder the authority (negative right) to prevent third parties from producing, selling, importing, or licensing their invention. 3. Patent Application and Priority Rights
A patent applicantThe greatest risk for an inventor is having their invention registered by someone else in another country. The mechanism that eliminates this risk is the “Priority Right”.
How the Priority Right Works: You have a 12-month period from the date of the first patent application in a country (for example, Türkiye). If you apply in other countries that are members of the Paris Convention within this period, your applications in foreign countries will be evaluated based on your “first application date” (the date in Türkiye).
Why is it Important? Thanks to this right, you gain time to register your invention in other countries for 12 months, while preventing your invention from being rejected by other inventors around the world on the grounds that it is “not new”. Your application is considered to have been “made before” all other applications (priority date).
In short;
The patent system is not only about registering a technical text, but also about correctly defining the boundaries of that technical text, protecting your moral rights as the inventor, and protecting your invention in the global market using strategic tools such as international priority rights. * You cannot obtain a patent: If your invention is a discovery or an unethical method.
You are a patent holder: If your registration is complete and you hold the moral rights to the invention.
••You are protected: If you have created a global protection shield by exercising your priority right.
Patent Law for Foreigners: Operation and International Protection
A patent right is by its nature a “regional” right. A patent obtained in Türkiye has no protective effect in the USA or Japan. This situation has made it necessary for the patent system to be coordinated at the international level for companies and inventors operating in the global economy. For foreign investors, inventors, or multinational companies operating in Türkiye, patent law operates within a “network of international treaties”.
The Principle of Reciprocity
The foundation of the patent system in Türkiye lies in “reciprocity”. For a foreigner to benefit from patent protection in Türkiye:
There must be a treaty between the state of which that person is a citizen and Turkey,
Or, the law of that state must grant similar rights to Turkish citizens regarding patents. Today, since Turkey is a member of the Paris Convention and the World Trade Organization, this reciprocity relationship has been established with almost all countries in the world. Therefore, a foreign natural or legal person can apply for and obtain patent protection in Türkiye under exactly the same conditions as Turkish citizens.
International Application Systems: Crossing Borders
It is costly and complex for a foreigner to apply separately in each country. Therefore, there are two main systems used:
Paris Convention (Priority Right): If a person who has applied for a patent in one country (for example, Germany) applies in Türkiye within 12 months, they can use the application date in Germany (the first application date) as the application date in Türkiye. This is called “Priority Right”. This prevents others from registering the same invention in that country. * PCT (Patent Cooperation Treaty): This system allows initiating the patent process in more than 150 countries with a single international application. When a foreign inventor applies through PCT, they can include Türkiye in the process. This offers the convenience of managing the patent acquisition process from a single center.
“Agent” Requirement for Foreigners
It is quite difficult for foreigners who are not resident in Türkiye (those who do not reside or have a place of business in Türkiye) to personally handle their transactions with the Turkish Patent and Trademark Office. Law No. 6769 requires foreigners who are not resident in Türkiye to conduct their transactions through “Trademark and Patent Agents”. These agents defend the rights of their foreign clients in Türkiye because they both know the legal language and are familiar with the technical stages of the process. 4. Strategic Recommendations for Foreign Clients
The basic roadmap for foreigners entering or innovating in Türkiye is as follows:
Preliminary Research: Before making an investment or selling a product in Türkiye, be sure to conduct a “Technical Research” to determine if a similar patent exists in Türkiye.
Exercise Priority Rights: If you have filed your application in your own country, file your application in Türkiye within 12 months.
Selection of Attorney: Working with an experienced patent attorney who is familiar with Turkish legislation and the case law of local courts increases the probability of a positive outcome by 80%.
Translation Accuracy: Patent specifications (technical texts) are written in very specific language. The translation must be done by a technical “patent translator”; otherwise, a wrong word could narrow the scope of the patent. 5. Customs Measures: If you have a patent in Türkiye, you can apply for “Industrial Property Rights Protection at Customs” to stop the entry of products infringing your patent into Türkiye. This is the most effective deterrent for foreign rights holders. Summary: WhatPatents in Türkiye?
Turkey, with its strategic location between Europe and Asia and its developing R&D centers, is an important “technology market” for foreign investors. For a foreigner, obtaining a patent in Türkiye is not just a legal process, but also an attempt to “operate safely under legal protection” in the Turkish market. Thanks to its integrated structure in international patent systems, Turkey offers a foreign rights holder the assurance of protection equivalent to that in their own country.
