In Turkish M&A practice, intellectual property due diligence is rarely a side exercise. In many deals, it is one of the main drivers of price, structure, post-closing integration, and indemnity allocation. This is especially true in technology, consumer goods, manufacturing, media, e-commerce, healthcare, life sciences, SaaS, gaming, franchising, and export-oriented businesses, where the target’s value may depend more on brands, software, know-how, data, designs, and patent rights than on its physical assets. Türkiye’s official Investment Office also lists intellectual property rights among the main legal topics investors should consider when entering the Turkish market, which reflects how central IP has become in business acquisitions and strategic investments.
A Turkish IP diligence exercise should never be reduced to asking whether the target has “a few trademarks.” The real legal questions are broader. Who actually owns the IP? Is the ownership chain complete and enforceable? Are the registered rights alive, renewed, and recorded correctly? Are key brands used in the form and classes in which they are registered? Are the patents, utility models, or designs still in force? Were the software and other copyright works created by employees or contractors, and if so, has ownership been documented properly? Are there recorded licenses, pledges, or structural changes in the relevant registries? Do trade secrets actually exist as protected confidential assets, or are they just undocumented know-how inside employee email accounts? And in data-heavy businesses, does the IP layer overlap with Turkish personal data law in a way that changes transaction risk?
This is why intellectual property due diligence in Turkish M&A transactions should be understood as a combined review of registered rights, unregistered rights, chain of title, use and enforceability, contractual restrictions, employee and contractor creation issues, data and confidentiality structures, and registry recordals. Under Turkish law, industrial property rights are mainly governed by Law No. 6769 on Industrial Property, while copyright and related rights are governed separately by Law No. 5846 on Intellectual and Artistic Works. The separation between these regimes matters in M&A because a target may have valuable trademarks and patents that can be checked in public registries, while its most important software, content, databases, and other copyrighted materials may require a very different diligence method focused on contracts and evidence rather than registration alone.
Why IP due diligence matters so much in Turkish deals
The commercial importance of IP due diligence in Turkey is straightforward. A buyer may believe it is purchasing a leading Turkish brand, a defensible product portfolio, proprietary code, or a scalable technology platform. But if the core brand is owned by a founder personally, if the software was written by contractors without clear assignment language, if the key patent annuities were not maintained, or if the main customer-facing domain names sit under a third party’s name, the buyer may not actually be getting what it thinks it is buying. Turkish law provides a solid framework for protecting trademarks, patents, utility models, designs, and copyright, but the existence of that framework does not cure weak ownership chains or poor record-keeping inside the target.
This issue is also structural. In a share deal, the buyer acquires the company with its existing IP history, disputes, licenses, and compliance posture. In an asset deal, the buyer may try to carve out specific brands, patent families, software assets, or licensing relationships. In either case, Turkish IP diligence is not just about identifying the rights; it is about determining whether those rights are transferable, enforceable, sufficiently documented, and commercially usable after closing. That is why the most important outputs of Turkish IP diligence are often not only risk summaries, but also concrete transaction terms: special indemnities, closing conditions, recordal obligations, assignment documents, transition services, re-signing of contractor IP clauses, and post-closing data-compliance projects.
The first layer: identify the target’s registered industrial property
The first workstream in a Turkish IP diligence review is to map the target’s registered industrial property. TÜRKPATENT, the Turkish Patent and Trademark Office, is the central authority for trademarks, patents, utility models, designs, geographical indications, and related industrial property services in Türkiye, and it provides public search interfaces for trademark, patent, and design research. That makes registry-based verification one of the most practical starting points in a Turkish M&A transaction. Buyers should independently review the TÜRKPATENT records rather than relying only on seller disclosure schedules.
From a legal framework perspective, the current Industrial Property Code entered into force in 2017 and, according to WIPO Lex, covers patents, utility models, trademarks, geographical indications, industrial designs, enforcement, the IP regulatory body, and, as secondary subject matter, undisclosed information and trade names. For diligence purposes, this is important because it confirms that Turkish industrial property review is not limited to patents and trademarks only. Depending on the target’s business, registered designs, utility models, trade names, and even trade-secret-related compliance may all sit inside the same broader industrial-property landscape.
A well-run Turkish registry review should at minimum verify the right holder name, registration numbers, application numbers, filing and renewal dates, goods-and-services coverage for trademarks, status of pending applications, and whether the rights are directly owned by the target or by another group entity, founder, shareholder, distributor, or licensing vehicle. In Turkish M&A practice, one of the most common surprises is that the target uses the brand and technology commercially, but does not actually own them in the corporate entity being sold. Registry searches often reveal that the nominal owner is a different company in the group or even a natural person.
Trademark diligence in Turkish M&A
Trademark diligence is usually the most commercially important part of Turkish IP review. TÜRKPATENT states on its official trademark page that trademark protection in Türkiye is granted under the Industrial Property Code No. 6769 and that the term of protection for a registered trademark is ten years from the application date, renewable for further ten-year periods. The same page also explains the official examination flow, opposition procedure, and publication process. These official points matter in M&A because buyers need to know not only whether a mark exists, but whether it is registered in the right owner name, in the right classes, and with enough remaining life to support the business plan.
Turkish trademark diligence should also examine use risk. TÜRKPATENT’s official trademark guidance states that when an earlier trademark relied on in opposition has been registered for at least five years, the Office may, at the applicant’s request, require the opponent to provide evidence of genuine use during the relevant five-year period or a proper reason for non-use. This does not by itself describe every non-use consequence in Turkish law, but it is a strong official indicator that genuine use remains legally significant. For M&A diligence, that means a buyer should not only review registration certificates; it should also verify that the target has real, documentable use of its core marks in Türkiye for the relevant goods and services.
Another important Turkish trademark diligence point is registry recordal. TÜRKPATENT’s official Trademark Fees page lists fees for the recording of a transfer or partial transfer, recording of structural changes such as merger or split, inheritance transfer, license registration and renewal, and recording of a pledge. This is highly relevant in M&A because it confirms that trademark registries should be checked not only for ownership, but also for existing licenses, pledges, and past structural changes. A brand that appears to be owned by the target may still be commercially constrained by a recorded license or encumbered by a recorded pledge.
In practice, Turkish trademark diligence should therefore cover more than validity. It should include brand architecture, core house marks, product marks, defensive filings, local Turkish filings versus Madrid designations, coexistence or consent arrangements, disputes, opposition history, pledges, licenses, and actual market use. For franchised or distributor-led businesses, diligence should also check whether local registration was made in the principal’s name or in the name of a local distributor or former business partner. That issue can materially affect closing leverage and post-closing enforcement.
Patent and utility model diligence
Patent diligence in Turkey requires a different emphasis. TÜRKPATENT provides official public search functionality for patent matters, and its official patent fees page shows that the Turkish system includes assignment recordal, license recordal, recordal of structural changes such as merger, division or contribution in kind, transfer by inheritance, pledge or security interest, and a series of annual renewal fees. This is very important for M&A diligence because a Turkish patent portfolio should be checked not only for registration status, but also for title recordals, encumbrances, structural changes, and annuity maintenance.
A buyer reviewing Turkish patents or utility models should therefore confirm at least four things. First, are the rights actually registered in the correct owner’s name? Second, are there recorded licenses, pledges, or structural changes affecting them? Third, have the necessary renewal fees been paid so the rights remain in force? Fourth, is the commercially relevant technology actually covered by the claims of the registered right, or is the patent portfolio weaker than the seller’s presentation suggests? The existence of public recordal and annuity mechanisms means these are diligence items that can and should be verified rather than accepted on trust.
Patent diligence in Turkey should also include the international chain. WIPO’s entry for the Turkish Industrial Property Code shows that Türkiye participates in key IP treaties, including the Patent Cooperation Treaty (PCT), the European Patent Convention (EPC), the Budapest Treaty, the Madrid Protocol, and other international frameworks. TÜRKPATENT also announced its participation in WIPO’s Digital Access Service (DAS) from June 2022. For M&A purposes, this means that Turkish patent diligence should not stop at domestic filings; it should also review whether the Turkish target’s inventions are part of a broader PCT, EP, or international priority chain and whether those links have been maintained correctly.
Design rights and product-facing businesses
For product businesses, consumer goods, fashion, furniture, packaging, industrial equipment, automotive parts, and visual-interface businesses, design rights can be a key diligence category. TÜRKPATENT provides an official design search interface, which means buyers can independently verify whether the target’s design portfolio exists, is active, and is recorded in the correct name. In Turkey, design portfolios often matter most where product differentiation is visual, and they can be overlooked in transactions that focus too heavily on brands and patents alone.
The practical risk in Turkish design diligence is often under-documentation. A seller may present a visually successful product line as “protected,” but the buyer still needs to verify whether that protection exists through registered designs, through copyright-style protection, through unfair-competition arguments, or through no formal right at all. A registered design search is therefore one of the most basic diligence steps for businesses whose commercial identity depends on appearance rather than only word marks or technical inventions.
Copyright and software diligence: separate law, different diligence method
Turkish copyright diligence sits under a different legal regime from industrial property. WIPO’s copyright entry for Türkiye confirms that Law No. 5846 on Intellectual and Artistic Works is the main copyright statute, while the Industrial Property Code separately governs patents, trademarks, and designs. The copyright law’s official WIPO text also defines computer programs and expressly includes computer programs and their preliminary designs among works of science and literature. This is one of the most important legal facts in Turkish software M&A: core software assets are not merely technical business tools; they are copyright-relevant works under Turkish law.
Because copyright is not diligence-ready in the same way as a trademark registry entry, Turkish software and content diligence depends heavily on chain of title. Buyers need to ask who wrote the code, under what employment or contractor terms, whether the company has clear written ownership or assignment language, whether open-source components are present, and whether any source-code escrow, third-party developer, university, or public-funded project rights complicate ownership. The legal separation between industrial property and copyright means that a buyer cannot rely on TÜRKPATENT search results alone to validate ownership of software, digital content, databases, manuals, marketing assets, or audiovisual works.
This is also where Turkish diligence often uncovers one of the biggest hidden risks in founder-led or startup-stage targets: the company uses the software, but the underlying authorship and transfer paperwork are incomplete. A Turkish buyer or foreign investor should therefore insist on reviewing founder agreements, employee IP clauses, contractor assignment agreements, outsourced-development contracts, and any internal invention or software policies. Without that, the target may own the business commercially but not own the codebase cleanly enough for a safe acquisition.
Employee inventions and R&D ownership
Employee-created IP is a particularly important diligence issue in Turkish technology, engineering, industrial, and R&D-heavy businesses. WIPO’s entry for the Turkish Industrial Property Code confirms that the current law is implemented in part by the Regulation on Employee Inventions, Inventions Realized within Higher Education Institutions and Inventions Arisen from Projects Supported by Public Authorities, and WIPO further notes that this regulation was issued pursuant to Articles 113 to 122 of the Industrial Property Code. This is a strong signal that employee inventions are not a marginal topic in Turkish law; they are a specifically regulated category.
For M&A diligence, the practical implication is that patent-owning or innovation-heavy Turkish targets should be asked how inventions were generated, whether invention notices were filed internally, whether the employer asserted the relevant rights properly, whether compensation issues were addressed, and whether any university or public-support dimension exists. These questions become even more important where the target’s value depends on patent families originating from employee or publicly supported research. A buyer does not want to discover after closing that the registered patents sit on top of a contested employee-invention record.
Licenses, encumbrances, and recordal risk
A core part of Turkish IP diligence is not ownership itself, but burdened ownership. TÜRKPATENT’s official fee pages show that the Turkish system recognizes and records a wide range of registry-side events, including assignment, license registration, merger or division recordal, inheritance transfer, and pledge or security interest for patents and utility models, and similar recording categories for trademarks. In other words, a right may be valid and owned by the target, but still not be free for a buyer to use as expected.
This means Turkish IP diligence should always check at least three separate ownership questions. First, who is the record owner? Second, is there a recorded license that limits exclusivity or field of use? Third, is there a pledge, structural-change recordal, or other encumbrance that affects transferability or enforcement value? In acquisition documents, this often leads to specific closing conditions requiring the release of pledges, termination or amendment of intragroup licenses, or post-closing recordals to align the registry with the transaction.
Domain names and online brand control
In many Turkish transactions, domain names are commercially as important as trademarks, especially for e-commerce, SaaS, media, and consumer-facing businesses. For Turkish country-code domains, the official TRABİS system provides public WHOIS functionality. That means buyers can and should verify whether the target actually controls its important .tr domain names, whether the registrant data matches the target or an authorized affiliate, and whether the key digital identifiers are fragmented across founders, agencies, distributors, or former employees.
Domain diligence in Turkey should therefore be handled as part of IP diligence, not only as an IT housekeeping matter. A target that owns strong trademarks but lacks control over the matching domain portfolio may be commercially exposed. The same is true where the business depends on app names, sub-brands, or market-facing online identities that are not aligned with the registered trademark and domain portfolio. In practice, Turkish buyers should reconcile TÜRKPATENT trademark searches with TRABİS domain ownership and with the actual consumer-facing brand architecture used by the target.
Trade secrets, know-how, and confidentiality architecture
Not every valuable IP asset in a Turkish target is registered. WIPO’s entry for the Industrial Property Code notes that the law’s secondary subject matter includes undisclosed information (trade secrets). That matters because many Turkish targets derive value from manufacturing methods, pricing models, customer lists, source code, formulas, datasets, internal workflows, or other know-how that is commercially critical but not registry-based. In a due diligence context, the key question is not whether these assets are “important,” but whether they are actually protected as confidential business assets through contracts, access controls, internal policies, and exit management.
A buyer should therefore ask practical questions: Are NDAs used consistently? Are source code, formulas, models, or customer datasets access-controlled? Do employment and contractor agreements contain confidentiality and IP clauses? Are there internal classification policies for confidential information? Have departing employees returned material and devices? In Turkish M&A, weak trade-secret hygiene can seriously reduce the value of unregistered IP, because the legal label “know-how” is much less useful if the business cannot show that the know-how was actually treated as confidential.
IP diligence now overlaps with Turkish personal data law
For software, platform, AI, SaaS, e-commerce, adtech, healthtech, fintech, and data-rich targets, IP diligence in Turkey now overlaps heavily with personal data protection. The official English text of the Turkish Personal Data Protection Law states that its purpose is to protect fundamental rights and freedoms, especially privacy, and to set out the obligations, principles, and procedures binding on natural and legal persons who process personal data. The law therefore applies well beyond classic “privacy companies” and can directly affect how a target exploits software, databases, analytics tools, customer records, and employee information.
This is why IP diligence for a Turkish technology target should not stop at source-code ownership and trademark filings. It should also check whether the target is subject to VERBIS registration obligations, because the official By-Law on Data Controllers’ Registry defines VERBIS as the internet-accessible system used by data controllers for registration and related operations. It should also examine cross-border data flows, because the official KVKK guidance on transfer of personal data abroad states that cross-border transfers are governed under Article 9 and depend on specified legal transfer conditions. In businesses where the product itself depends on data processing, weak KVKK compliance can materially affect the commercial usability of the underlying software and databases.
International filings and foreign coverage
Turkish IP diligence should also test whether the target’s protection strategy is local only or international. TÜRKPATENT’s trademark guidance states that protection in Türkiye can be sought either by direct filing before TÜRKPATENT or through the Madrid System, and the WIPO entry for the Industrial Property Code lists Türkiye’s participation in major international frameworks such as the Madrid Protocol, PCT, and EPC. For acquisitive buyers and investors, this means the Turkish target’s IP position should be reviewed as a portfolio, not just as isolated local rights. A Turkish mark may be strategically weak if the target’s export markets are uncovered, and a Turkish patent filing may be commercially limited if the international family was not pursued consistently.
What a Turkish IP due diligence checklist should cover
A robust Turkish IP due diligence checklist should usually cover the following: all registered trademarks, patents, utility models, and designs; TÜRKPATENT search verification; renewal and annuity status; ownership-chain review; assignments, licenses, pledges, and structural recordals; software and copyright chain-of-title review; employee and contractor IP clauses; employee invention procedures; trade-secret controls; domain-name ownership through TRABİS; key disputes and oppositions; open-source and third-party code use; data-protection and VERBIS status for data-centric targets; and international filing chains where relevant. None of these items is theoretical in Turkey; each corresponds to a real legal or operational layer visible in the official Turkish and WIPO materials.
The diligence report should then feed directly into transaction documents. In Turkish M&A practice, IP findings often support specific warranties on title, validity, use, non-infringement, employee ownership, and absence of encumbrances; specific indemnities for known disputes or chain-of-title problems; closing conditions for assignments or releases; and post-closing undertakings to complete recordals or data-compliance work. The point of IP diligence is not only to list risks. It is to convert them into a transaction structure the buyer can actually live with.
Conclusion
Intellectual Property Due Diligence in Turkish M&A Transactions is ultimately about verifying that the target’s intangible assets are real, owned, protected, and transferable in the way the deal model assumes. Turkish law gives a strong framework for industrial property through Law No. 6769, public search and recordal systems through TÜRKPATENT, copyright protection through Law No. 5846, employee invention regulation under the Industrial Property Code, domain-name visibility through TRABİS, and data-governance rules through the Personal Data Protection Law and VERBIS regime. But those systems do not remove the need for disciplined diligence. They make disciplined diligence possible.
For buyers, sellers, founders, and investors, the practical message is simple. In a Turkish transaction, IP diligence should not be treated as a branding appendix. It should be treated as a core legal workstream that tests registered rights, unregistered rights, ownership chains, licenses, employee-created IP, software provenance, trade-secret controls, domains, and data compliance. The strongest Turkish M&A deals are usually the ones where the buyer understands, before signing, whether the target’s intangible value is truly owned by the company being sold.
