Introduction
For startups, intellectual property is often the most important asset reviewed during a funding round. A company may have a promising product, strong founders, early customers and attractive revenue projections, but if it cannot prove that it owns or controls its intellectual property, investors may hesitate, reduce valuation, demand additional warranties or postpone closing.
In Turkey, investor IP due diligence is particularly important for technology startups, SaaS companies, mobile applications, fintech platforms, healthtech businesses, gaming companies, marketplaces, e-commerce brands, manufacturing startups, design-focused businesses and R&D-driven ventures. Investors want to know whether the company owns its brand, software, source code, domain names, patents, product designs, trade secrets, data infrastructure and commercial rights.
The Turkish legal framework includes several key laws. Industrial property rights such as trademarks, patents, utility models and industrial designs are mainly governed by the Industrial Property Code No. 6769, which WIPO identifies as Turkey’s main law covering patents, utility models, trademarks, industrial designs and enforcement of IP rights. Copyright protection is governed by Law No. 5846 on Intellectual and Artistic Works, which covers copyright and related rights in Turkey. Unfair competition and certain trade secret-related issues are addressed under the Turkish Commercial Code No. 6102, including Articles 54–63 on unfair competition and provisions relating to undisclosed information.
This article explains what investors usually examine during IP due diligence in Turkey, why IP problems can delay or damage funding rounds, and how startups can prepare a clean, credible and investment-ready IP portfolio.
1. What Is IP Due Diligence?
IP due diligence is the legal review of a company’s intellectual property assets, ownership chain, registration status, licenses, infringement risks, confidentiality systems and technology rights. It is usually conducted before a seed investment, venture capital round, private equity transaction, merger, acquisition, strategic partnership, licensing deal or exit.
For startups, IP due diligence answers several essential questions:
- Does the startup own the IP it claims to own?
- Are trademarks, patents, designs and domain names registered in the correct name?
- Was the software created by employees, founders, freelancers or agencies?
- Were IP rights properly assigned to the company?
- Are there unresolved disputes with former founders, employees or contractors?
- Is the startup infringing third-party rights?
- Are confidential materials protected?
- Are open-source software obligations properly managed?
- Are customer data and technology assets legally usable?
- Can the company scale, license, franchise or sell the product without IP restrictions?
From an investor’s perspective, IP due diligence is not merely a legal formality. It is a risk assessment. If the main software code belongs to a former contractor, the brand is not registered, the domain is owned by a founder personally, or the product depends on unlicensed third-party technology, the startup’s value may be significantly affected.
2. Why IP Due Diligence Matters in Turkish Funding Rounds
In Turkish startup investments, due diligence often focuses on corporate records, cap table, tax matters, employment, data protection, contracts and intellectual property. IP issues are especially sensitive because many startups are asset-light. They may not own factories, real estate or large physical infrastructure. Their main value may be software, brand, customer data, know-how, platform architecture, product design or patentable technology.
A startup that cannot prove IP ownership may face:
- Lower valuation
- Investor holdbacks
- Delayed closing
- Additional representations and warranties
- Founder indemnity obligations
- Requests for IP assignment before closing
- Requirement to settle disputes before funding
- Refusal of investment
- Future exit problems
Investors want certainty. They do not want to invest in a company whose core product can be challenged by a former developer, designer, co-founder, university, employer, supplier or competitor.
3. Trademark Due Diligence: Brand Ownership and Market Identity
Trademark review is one of the first areas of IP due diligence. A startup’s name, logo, product name, application name, platform name and slogans may all be commercially important. In Turkey, trademark protection is granted under Industrial Property Code No. 6769, and TÜRKPATENT confirms that trademark applications may be filed directly before the Turkish Patent and Trademark Office or through the Madrid System where applicable.
Investors usually examine whether:
- The startup has filed trademark applications.
- The marks are registered or still pending.
- The applicant is the company, not an individual founder.
- The trademark classes match the actual and planned business.
- There are oppositions, refusals or cancellation risks.
- Similar third-party marks exist.
- The startup has international trademark coverage if expansion is planned.
- The brand is descriptive, generic or weak.
- The domain name and trademark strategy are aligned.
A common startup mistake is using a brand publicly before conducting a trademark search. Another mistake is registering a trademark in the founder’s personal name and later forgetting to assign it to the company. Investors may require assignment of the mark to the startup before closing.
A strong trademark portfolio shows that the startup has protected its market identity and reduced the risk of future rebranding.
4. Patent and Utility Model Due Diligence
If the startup is technology-driven, investors will review whether the company has patentable inventions or existing patent and utility model applications. Patent due diligence is especially relevant for hardware, biotechnology, medical devices, engineering solutions, manufacturing processes, robotics, artificial intelligence infrastructure, chemicals, energy technologies and industrial products.
The investor will usually ask:
- Does the startup own any patent or utility model applications?
- Are applications filed in Turkey, internationally or under the PCT system?
- Were inventions disclosed before filing?
- Are inventors correctly named?
- Have inventors assigned their rights to the company?
- Were inventions created during employment or consultancy?
- Are maintenance fees paid?
- Are there office actions, objections or invalidity risks?
- Is the patented technology actually used in the product?
- Does the startup depend on third-party patents?
For patentable technology, timing is critical. Public disclosure before filing can damage novelty and weaken protection. Investors may therefore ask when the invention was created, when it was disclosed, when it was filed and who had access to technical information.
A startup should prepare invention disclosure forms, lab notes, prototype records, R&D documentation, patent attorney correspondence, filing receipts and assignment documents before due diligence begins.
5. Industrial Design Due Diligence
For product-based startups, industrial design rights may be central. Product shape, packaging, user interface graphics, physical product appearance, fashion items, furniture, accessories, electronic casings and consumer goods may have protectable visual features.
TÜRKPATENT explains that designs may be protected through registration and, under certain conditions, as unregistered designs first made available to the public in Turkey; registered design protection lasts five years and may be renewed in five-year periods up to twenty-five years, while unregistered design protection lasts three years.
Investors may review:
- Registered design certificates
- Pending design applications
- Product launch dates
- Public disclosure history
- Designer agreements
- Assignment of design rights
- Similar market designs
- Copying or infringement disputes
- Whether designs are ornamental or functional
- International design filing strategy
If the product’s appearance is part of the startup’s competitive advantage, lack of design protection can be a serious weakness. This is especially true when competitors can easily copy the product once it enters the market.
6. Copyright Due Diligence: Software, Content and Creative Assets
Many startups rely on copyright-protected assets: source code, website content, mobile app screens, photographs, videos, graphic designs, marketing materials, product manuals, training content, databases and software architecture documents.
In Turkey, copyright law is governed by Law No. 5846 on Intellectual and Artistic Works, which WIPO identifies as Turkey’s main copyright legislation. For software startups, copyright due diligence often becomes one of the most important parts of the investment review.
Investors usually ask:
- Who wrote the source code?
- Were developers employees, freelancers, agencies or founders?
- Are written IP assignment agreements available?
- Does the company have access to repositories?
- Are commit histories documented?
- Are third-party libraries properly licensed?
- Are open-source components compliant?
- Are UI/UX designs owned by the company?
- Were photographs, videos and graphics created internally or licensed?
- Does the startup have written rights to use all website and marketing content?
The biggest mistake is assuming that payment equals ownership. Paying a freelancer or agency does not automatically solve all copyright transfer issues. Investors often require written agreements showing that economic rights have been transferred or licensed broadly enough for the company’s business model.
7. Software Ownership and Source Code Review
For SaaS, fintech, gaming, AI, marketplace and mobile app startups, software ownership is usually the core due diligence issue.
The startup should be ready to show:
- Repository access records
- Developer identities
- Employment or contractor agreements
- IP assignment clauses
- Open-source software list
- Third-party API licenses
- Source code escrow arrangements, if any
- Cloud infrastructure contracts
- Security policies
- Version control history
- Documentation of proprietary modules
Investors may also examine whether the company’s product depends too heavily on code written before incorporation. If a founder developed the first version personally before the company was established, that founder should assign relevant IP rights to the company. If an external software house built the MVP, the service agreement must clearly transfer rights or provide a sufficiently broad license.
A startup should resolve these issues before the data room opens.
8. Open-Source Software Risks
Open-source software is common in startup development. It is not inherently problematic, but it must be managed. Investors may review whether the startup uses open-source components under permissive or restrictive licenses and whether any license obligations affect commercialization.
Common questions include:
- Does the product include GPL, AGPL or similar copyleft components?
- Are attribution obligations satisfied?
- Is the startup required to disclose source code?
- Are open-source notices maintained?
- Are components updated for security?
- Is there a software bill of materials?
- Did developers copy code from unauthorized sources?
For a software startup, an open-source compliance problem can become a valuation issue. A simple internal policy and software inventory can prevent serious due diligence concerns.
9. Founder IP Assignments
Many startups begin informally. Founders brainstorm ideas, create prototypes, write code, design logos, buy domains and prepare pitch decks before the company is incorporated. After incorporation, they may assume everything belongs to the company. Legally, that assumption can be dangerous.
Investors may ask whether all founder-created IP has been assigned to the company. This includes:
- Source code
- Product designs
- Business plans
- Brand names
- Logos
- Domain names
- Patentable inventions
- Databases
- Pitch materials
- Confidential know-how
A founder IP assignment agreement should transfer all relevant rights to the company and confirm that no founder retains conflicting ownership. This is particularly important if a founder leaves before the funding round.
Unresolved founder IP issues can create severe investor concern because a former founder may later claim rights in the startup’s core product.
10. Employee Inventions and Employment Agreements
If employees helped create the startup’s technology, employment documents should be reviewed. Investors may ask whether employment agreements contain confidentiality, IP ownership, invention disclosure, non-solicitation and post-termination obligations.
For technical teams, a startup should have:
- Written employment agreements
- Confidentiality clauses
- Invention assignment mechanisms
- Internal R&D documentation
- Access control policies
- Return-of-company-property clauses
- Clear rules for side projects
- Personal device and repository access policies
The goal is to show that the startup, not individual employees, controls the technology developed within the scope of work.
11. Freelancer, Agency and Consultant Agreements
Startups often outsource design, software development, marketing, content production, branding, industrial design, product prototyping and business consulting. These relationships are a frequent source of IP problems.
Investor due diligence will check whether agreements with freelancers and agencies contain:
- Clear scope of work
- IP transfer or license clauses
- Deliverable ownership terms
- Source file delivery obligations
- Confidentiality provisions
- Warranties against infringement
- Restrictions on reuse
- Portfolio/publicity restrictions
- Termination and handover rules
- Dispute resolution clauses
If a startup used an agency to create its logo but has no written agreement, the investor may require a retrospective assignment. If a software contractor built the app but retained ownership of reusable modules, the investor will want to understand whether the company’s rights are sufficient.
12. Domain Names, Social Media and Digital Assets
A startup’s digital assets are part of its IP due diligence package. Investors will usually examine whether the company controls its domain names, hosting accounts, social media handles, app store accounts, marketplace seller accounts and advertising accounts.
The company should prepare:
- Domain ownership records
- Registrar account details
- Renewal status
- DNS control documentation
- Social media account ownership
- App store developer account records
- Google, Meta, Apple, GitHub and cloud platform access records
- Agreements transferring accounts from founders or agencies
A major red flag appears when the main domain is registered personally by a founder, former employee or marketing agency. Before a funding round, startups should move all key digital assets under company control.
13. Trade Secrets and Confidential Know-How
Not every valuable startup asset is registrable. Algorithms, business methods, customer acquisition strategies, pricing models, supplier terms, technical recipes, manufacturing know-how, sales scripts and investor materials may be protected as trade secrets or confidential information.
The Turkish Commercial Code includes unfair competition and undisclosed information-related provisions, making confidentiality management important for commercial protection.
Investors may ask:
- Does the startup identify confidential information?
- Are NDAs used with investors, suppliers and contractors?
- Are employees bound by confidentiality clauses?
- Is sensitive information access-limited?
- Are documents marked confidential?
- Are customer lists and pricing models protected?
- Are trade secrets stored securely?
- Has any confidential information been leaked or misused?
Trade secret protection depends on behavior. If the startup treats valuable information casually, it becomes harder to argue that it was confidential.
14. Data Protection and IP Due Diligence
For many digital startups, data is a core commercial asset. However, data must be collected, processed, stored and transferred lawfully. In Turkey, personal data protection is governed by Law No. 6698 on the Protection of Personal Data. The Turkish Personal Data Protection Authority states that the purpose of the law is to protect fundamental rights and freedoms, especially privacy, and to regulate obligations and procedures for persons processing personal data.
Although data protection is not identical to IP law, investors often review it together with technology due diligence because customer databases, user analytics, health data, financial data and behavioral data may be commercially valuable.
Investors may ask:
- Does the startup lawfully collect personal data?
- Are privacy notices prepared?
- Are explicit consent mechanisms used where required?
- Are data processing agreements signed with vendors?
- Are cross-border transfer rules considered?
- Is sensitive personal data processed?
- Are data retention and deletion policies in place?
- Has there been any data breach?
- Are user databases usable for the intended business model?
A startup that cannot lawfully use its own data may lose a major part of its commercial value.
15. IP Disputes and Infringement Risks
Investors will also examine whether the startup is involved in any IP disputes or whether it may be infringing third-party rights.
The review may cover:
- Trademark oppositions
- Cease-and-desist letters
- Copyright claims
- Patent infringement allegations
- Domain disputes
- Former contractor claims
- Former founder disputes
- Employee invention claims
- Unfair competition allegations
- Platform takedown notices
- Marketplace complaints
Startups should disclose disputes honestly. Concealing an IP dispute is often worse than the dispute itself. Investors can usually tolerate manageable legal risk if it is identified, quantified and supported by a strategy.
16. IP Licenses and Commercial Agreements
A startup may not own every piece of technology it uses. It may license software, APIs, datasets, images, music, fonts, cloud infrastructure, payment systems, AI models or industrial components. Investors will review whether these licenses are sufficient for the startup’s business.
Important questions include:
- Is the license exclusive or non-exclusive?
- Is it transferable?
- Can it be sublicensed?
- Does it cover Turkey and international markets?
- Does it allow commercial use?
- Are there revenue-sharing obligations?
- Can the licensor terminate easily?
- Is the startup dependent on one critical license?
- Does a change of control require consent?
If the startup’s product depends on a license that can be terminated at any time, investors may see this as a material risk.
17. Preparing the IP Data Room
A well-organized IP data room makes the due diligence process faster and builds investor confidence. The startup should create folders such as:
Trademark Folder
- Trademark registrations
- Trademark applications
- Search reports
- Opposition records
- Renewal deadlines
- Brand guidelines
Patent and Utility Model Folder
- Applications
- Filing receipts
- Invention assignments
- Office actions
- Patent attorney correspondence
- Maintenance fee records
- R&D documentation
Design Folder
- Design registrations
- Product images
- Disclosure history
- Designer assignments
- Packaging files
Copyright and Software Folder
- Source code ownership documents
- Developer agreements
- Repository records
- Software architecture notes
- Open-source inventory
- UI/UX files
- Content ownership records
Contracts Folder
- Founder IP assignments
- Employee agreements
- Freelancer agreements
- Agency agreements
- Consultant agreements
- License agreements
- NDAs
Digital Assets Folder
- Domain records
- Social media handles
- App store accounts
- Hosting and cloud accounts
- Access control policy
Disputes Folder
- Warning letters
- Settlement agreements
- Opposition proceedings
- Litigation documents
- Takedown notices
A clean data room reduces investor friction and strengthens the startup’s negotiating position.
18. Common IP Red Flags in Turkish Startup Investments
Investors may become concerned if they find:
- No trademark application for the main brand
- Trademark filed in a founder’s personal name
- Similar third-party trademarks
- Software created without written assignment
- Freelancers paid without contracts
- Former founder claiming ownership
- Domain registered by an individual
- Open-source software with unclear obligations
- Public disclosure before patent filing
- No confidentiality measures
- Missing employee agreements
- Unclear ownership of product designs
- Unlicensed images, music, fonts or datasets
- Personal data collected without proper legal basis
- Ongoing IP disputes not disclosed
- Overbroad claims that “the idea is protected” without actual rights
These issues do not always kill an investment, but they usually require legal cleanup.
19. Practical Pre-Funding IP Checklist for Startups in Turkey
Before approaching investors, Turkish startups should:
- Conduct a trademark search.
- File trademark applications for the main brand and product names.
- Confirm that applications are filed in the company’s name.
- Identify patentable inventions before public disclosure.
- File patent or utility model applications where appropriate.
- Register product or packaging designs if appearance matters.
- Obtain founder IP assignment agreements.
- Review all employee contracts.
- Sign IP assignment agreements with freelancers and agencies.
- Prepare a software ownership file.
- Create an open-source software inventory.
- Secure domain names and social media accounts under company control.
- Prepare NDAs and confidentiality policies.
- Review data protection compliance.
- Collect evidence of ownership and development history.
- Disclose existing disputes clearly.
- Organize an IP data room.
- Create an IP roadmap for post-investment growth.
This checklist should be completed before the term sheet stage whenever possible.
20. Why Early IP Planning Improves Valuation
Strong IP preparation can improve a startup’s investment position because it shows legal maturity. Investors are more likely to trust a company that can prove ownership, reduce infringement risk and demonstrate a scalable protection strategy.
A strong IP portfolio may help the startup:
- Defend its brand
- Prevent copycats
- License technology
- Expand internationally
- Franchise or distribute products
- Negotiate with strategic partners
- Attract institutional investors
- Prepare for exit
- Increase valuation credibility
In contrast, unresolved IP problems can create uncertainty. Investors may ask for conditions precedent, escrow, indemnities, founder undertakings or valuation discounts.
FAQ: Investor IP Due Diligence in Turkey
What is investor IP due diligence?
Investor IP due diligence is the legal review of a startup’s intellectual property assets, ownership documents, registrations, software rights, licenses, disputes and infringement risks before investment.
Do Turkish startups need trademark registration before investment?
It is strongly advisable. Trademark registration or at least a pending application helps show that the startup is protecting its brand and reducing online and market conflict risks.
Is software automatically owned by the startup?
Not always. If software was created by founders, employees, freelancers or agencies, investors will examine whether the company has valid ownership or license rights.
Are patents necessary for every startup?
No. Patents are relevant mainly where the startup has a technical invention. Many software, marketplace or service startups rely more on copyright, trade secrets, contracts, trademarks and data strategy.
Why do investors review open-source software?
Open-source components may impose license obligations. Some licenses can affect commercialization or source code disclosure. Investors want to ensure compliance.
What is the biggest IP mistake Turkish startups make?
One of the biggest mistakes is building the product with founders, freelancers or agencies without written IP assignment agreements, then trying to fix ownership only during the funding round.
Conclusion
Investor IP due diligence in Turkey is not merely a legal checklist. It is a test of whether the startup truly owns and controls the assets that create its value. For technology and innovation-driven companies, intellectual property may be the foundation of the entire investment case.
A startup preparing for a funding round should organize its trademarks, patents, designs, software rights, copyright records, founder assignments, employee agreements, contractor contracts, domain names, trade secrets, data compliance documents and licensing arrangements before investors begin formal review. The stronger the IP file, the smoother the investment process.
Turkish startups should not wait for investor questions to reveal legal gaps. Early IP planning protects valuation, reduces negotiation pressure and makes the company more credible. In a competitive funding environment, an investment-ready IP portfolio can be the difference between a delayed deal and a successful closing.
