Introduction
For startups, intellectual property is often the core value of the company. A startup may not own large factories, real estate or physical assets, but it may own software, source code, trademarks, product designs, algorithms, mobile applications, artificial intelligence models, technical inventions, customer databases, confidential know-how, domain names and brand identity. These assets may determine whether the company can attract investors, sign enterprise customers, license technology, defend itself against competitors or complete a successful exit.
However, one of the most common legal problems in Turkish startup practice is simple: the company uses the intellectual property, but it does not clearly own it.
The brand may have been created by a freelance designer. The first software version may have been written by a technical founder before incorporation. The product design may have been prepared by an external agency. The invention may have been developed jointly by founders, employees and consultants. The domain name may be registered in the personal account of one founder. The logo may have been paid for, but no copyright assignment was signed. The patent application may be filed in the name of an individual inventor rather than the company.
This is where IP assignment agreements become essential.
An IP assignment agreement is a legal contract by which the owner or creator of intellectual property transfers ownership or economic rights to another person or company. For startups in Turkey, these agreements are not merely administrative documents. They are foundational legal instruments that convert founder contributions, freelancer deliverables, employee-created works and contractor outputs into company-owned assets.
Turkey’s main legal framework for intellectual property includes the Industrial Property Code No. 6769, which covers trademarks, patents, utility models, industrial designs and related enforcement mechanisms, and the Law No. 5846 on Intellectual and Artistic Works, which governs copyright and related rights. WIPO identifies Law No. 6769 as Turkey’s main industrial property statute, while Law No. 5846 is the key copyright statute in Turkey.
This article explains how IP assignment agreements work in Turkey, why startups should secure ownership early, which assets must be assigned, what formal requirements matter, what mistakes founders make, and how a clean IP ownership structure improves investment readiness.
1. What Is an IP Assignment Agreement?
An IP assignment agreement is a contract that transfers ownership or transferable economic rights in intellectual property from one party to another. In a startup context, the assignor may be a founder, employee, freelancer, software developer, designer, consultant, agency, inventor or external collaborator. The assignee is usually the startup company.
An assignment is different from a license. A license gives permission to use IP under certain conditions, while ownership remains with the licensor. An assignment transfers ownership or the relevant economic rights to the assignee. This distinction is critical.
For example, if a freelance developer grants the startup a limited license to use software, the developer may still own the code. If the developer assigns the relevant economic rights to the startup, the startup has a much stronger ownership position. Similarly, if a founder personally owns a trademark and only allows the company to use it informally, the startup may face serious problems during fundraising. If the founder assigns the trademark to the company, the ownership chain becomes clearer.
An IP assignment agreement may cover:
- Trademarks
- Trademark applications
- Software source code
- Copyrighted materials
- Website content
- Mobile application code
- Product designs
- Industrial design applications
- Patentable inventions
- Patent applications
- Utility models
- Databases
- Domain names
- Trade secrets and know-how
- Technical drawings
- Product documentation
- Branding materials
- AI model documentation, prompts or datasets
- Marketing content and visual assets
A startup should not assume that one generic clause automatically solves every ownership issue. Different IP categories require different legal treatment.
2. Why Startups Must Secure IP Ownership Early
Startups often begin informally. Founders meet, develop an idea, create a prototype, hire a freelancer, buy a domain, prepare a pitch deck and launch a landing page before the company’s legal structure is fully ready. This speed is commercially understandable, but legally dangerous.
If IP ownership is not secured early, several risks arise:
- A founder may later claim personal ownership of the brand or software.
- A freelancer may refuse to deliver source files or claim additional payment.
- An agency may reuse similar designs for a competitor.
- An investor may delay funding until missing assignments are signed.
- A former employee may claim rights in code or technical inventions.
- A patent application may be filed in the wrong name.
- The company may be unable to enforce IP rights against infringers.
- A buyer may reduce valuation during acquisition due diligence.
- A strategic partner may refuse to sign a licensing deal.
- A startup may be forced to rebrand or rebuild technology.
The earlier the assignment is signed, the stronger the company’s legal position becomes. Retrospective assignments are possible in many situations, but they are harder to obtain once a dispute arises or once the IP becomes valuable.
A startup should treat IP assignment as part of company formation, not as a document to prepare only when investors ask for it.
3. Founder IP Assignments
Founder IP assignment is one of the most important documents for any startup. Before incorporation, founders may create significant assets: the business name, logo, domain, first software prototype, pitch deck, technical concept, product drawings, customer list, algorithm, database structure or invention.
After incorporation, these assets should be transferred to the company through a written founder IP assignment agreement. Otherwise, the startup may use assets that legally remain with individual founders.
A founder IP assignment should cover:
- Pre-incorporation IP
- Future IP created for the company
- Source code and software architecture
- Brand names and logos
- Domain names and social media accounts
- Patentable inventions
- Design files and prototypes
- Confidential business information
- Investor materials
- Product documentation
- Databases and technical materials
- Cooperation for future filings or registrations
This agreement is especially important if one founder leaves. Without a written assignment, the departing founder may claim that the company’s product, code, brand or invention cannot be used without consent.
Investors pay close attention to this issue. A startup with clean founder assignment documents appears more mature, reliable and legally investable.
4. Assignment of Copyright and Software Rights
Copyright is highly relevant for startups because many startup assets are copyright-protected or copyright-adjacent: source code, user interfaces, website content, photographs, videos, design files, manuals, pitch decks, documentation, training content and marketing materials.
Turkish copyright law is governed by Law No. 5846. Under this law, computer programs and preparatory designs leading to software are recognized within the copyright framework, while the ideas and principles underlying a computer program are not protected in the same way as the expression of the program itself.
One of the most important points is the form requirement. Turkish copyright law requires contracts concerning economic rights to be made in writing and the relevant rights to be specified individually. This rule is crucial for IP assignment agreements involving software, creative works and content.
For this reason, a software assignment agreement should not simply say, “all software rights belong to the company.” It should specify the rights being transferred, such as:
- Reproduction
- Distribution
- Adaptation and modification
- Processing and derivative works
- Public communication
- Publication
- Commercial use
- Licensing and sublicensing
- Transfer to third parties
- Integration into other products
- Use in SaaS, mobile, API and enterprise environments
- Use in Turkey and internationally
- Use for the full legal protection period
For software startups, the agreement should also require delivery of source code, object code, repositories, credentials, technical documentation, API documentation, deployment scripts, database schemas, architecture diagrams and related materials.
The safest approach is to sign written IP assignment agreements with every developer, agency and contractor before development begins.
5. Freelancer and Agency Assignments
Many startups outsource important work to freelancers and agencies. A designer may create the logo. A software house may build the MVP. A branding agency may prepare the visual identity. A marketing consultant may create campaign materials. An industrial designer may prepare product renderings. A photographer may produce product images.
Payment alone should not be treated as full IP ownership. A startup should obtain a written assignment or sufficiently broad license depending on the commercial purpose.
Freelancer and agency IP assignment agreements should include:
- Clear description of deliverables
- Transfer of economic rights
- Permission to modify and adapt the work
- Right to register trademarks or designs based on the work
- Delivery of editable source files
- Warranty of originality
- Disclosure of third-party materials
- Confirmation that stock assets, fonts, templates and music are licensed
- Prohibition on unauthorized reuse
- Confidentiality obligations
- Indemnity for third-party infringement claims
- Post-termination cooperation
Agencies often use subcontractors. The agency cannot validly transfer rights it does not own or control. Therefore, the agency agreement should state that the agency has secured all necessary rights from its employees, freelancers and subcontractors.
This point becomes critical during investor due diligence. Investors may ask whether the startup owns its logo, website, software, videos, product photos and interface designs. If the startup cannot prove ownership, funding may be delayed.
6. Employee-Created IP
Startups also need to regulate IP created by employees. Technical employees, software developers, designers, marketers, engineers and product managers may create valuable assets during employment.
Employment agreements should include:
- Confidentiality clauses
- IP ownership clauses
- Invention disclosure obligations
- Assignment of economic rights where necessary
- Cooperation for patent, utility model, design and trademark filings
- Return of company property
- Restrictions on unauthorized copying of source code and data
- Post-employment confidentiality obligations
- Rules on side projects
- Use of company devices, repositories and accounts
Although Turkish law contains certain rules regarding works created during employment, startups should not rely on general assumptions. Written employment agreements and internal IP policies reduce ambiguity.
For technical inventions, employee invention rules and patent assignment issues should be handled carefully, especially where R&D teams develop patentable technologies. If the startup operates in a technopark, university collaboration or publicly funded project environment, additional rules may apply.
7. Trademark Assignment in Turkey
Trademarks are among the most important IP assets for startups. The company name, product name, app name, logo and platform brand should usually be owned by the company.
Trademark protection in Turkey is governed by Industrial Property Code No. 6769, and TÜRKPATENT states that trademark protection is granted under this Code.
A trademark assignment may be necessary where:
- A founder filed the trademark personally before incorporation.
- A foreign parent company transfers the mark to a Turkish subsidiary.
- A startup acquires another brand.
- A joint venture centralizes brand ownership.
- A company restructures its IP holding model.
- A logo or product name is moved from an individual to the company.
Industrial Property Code No. 6769 recognizes that industrial property rights may be transferred, licensed, inherited, pledged, used as security and made subject to other legal transactions. The Code also provides that certain transactions not recorded in the registry cannot be asserted against good-faith third parties, and it includes specific provisions for trademark transfers.
In practice, trademark assignment should be made in writing, properly executed, and recorded before TÜRKPATENT where necessary to ensure public registry clarity. For startups, the most important practical point is simple: the trademark record should match the company’s actual business structure. If the company uses the brand, the company should usually own or clearly license the mark.
8. Patent, Utility Model and Invention Assignments
Patent and utility model assignments are important for technology, hardware, AI, biotech, medical device, engineering, manufacturing and industrial startups.
Industrial Property Code No. 6769 governs patents and utility models in Turkey. WIPO identifies the Code as covering patents, utility models, trademarks and industrial designs.
In invention-based startups, the following questions must be answered early:
- Who created the invention?
- Was it created before or after incorporation?
- Was it created by founders, employees, consultants or university researchers?
- Were all inventors correctly identified?
- Who owns the right to file the patent application?
- Was an assignment signed?
- Has the invention been publicly disclosed?
- Are there foreign filing plans?
- Is there a university, employer or grant-related claim?
- Who will pay patent prosecution and maintenance costs?
A patent assignment agreement should clearly transfer the right to apply for, prosecute, maintain, enforce, license and commercialize the invention. It should also require the inventor or assignor to cooperate in signing future documents, responding to patent office requests and supporting international filings.
Patent assignments are particularly important before fundraising. Investors want to know that the company owns the technology it claims to own, not merely that founders or consultants developed it informally.
9. Industrial Design Assignments
Industrial design rights are relevant for product appearance, packaging, consumer goods, fashion, furniture, accessories, hardware, device casings, interface visuals and product aesthetics.
If a product’s appearance is created by an external designer, agency or founder, the startup should secure assignment before filing a design application or launching the product. If the company fails to do so, the designer may later challenge ownership or claim compensation.
A design assignment should cover:
- Product sketches
- CAD files
- 3D models
- Packaging designs
- Surface patterns
- UI visuals
- Prototype images
- Manufacturing drawings
- Design registration rights
- Right to modify and commercialize the design
- Right to file applications in Turkey and abroad
- Right to enforce against infringers
For startups in consumer products, cosmetics, fashion, electronics or packaging-heavy sectors, industrial design assignment may be as important as trademark or software assignment.
10. Domain Names and Digital Assets
Domain names and digital assets are not always traditional IP rights, but they are essential to startup ownership. A startup should ensure that all key digital assets are controlled by the company.
Assignment or transfer documents may be needed for:
- Domain names
- Hosting accounts
- App store accounts
- Social media handles
- GitHub or GitLab repositories
- Cloud accounts
- Advertising accounts
- Analytics accounts
- Marketplace seller accounts
- Email systems
- Design platform accounts
- API keys and developer accounts
A founder or agency may initially register these assets. Before a funding round, all critical accounts should be transferred to the company or placed under company-controlled administrative access.
A startup that owns its trademark but not its domain may still face operational risk. Investors will review digital asset control as part of broader IP due diligence.
11. Trade Secrets and Know-How
Trade secrets and know-how are not “assigned” in the same way as a registered trademark or patent, but they must be contractually controlled. A startup’s value may depend on confidential information such as algorithms, training data, supplier lists, pricing models, customer acquisition methods, manufacturing formulas, internal workflows, technical documentation and business strategy.
IP assignment agreements should be supported by confidentiality obligations. The assignor should confirm that confidential materials created or collected for the startup belong to the company and may not be used outside the company’s business.
The agreement should also require:
- Return or deletion of confidential information
- No unauthorized disclosure
- No competing use of trade secrets
- Transfer of documentation and files
- Cooperation in evidence preservation
- Post-termination confidentiality
- Access restriction to repositories and data rooms
Trade secret protection depends heavily on actual behavior. If the startup does not treat information as confidential, it becomes harder to enforce confidentiality later.
12. Background IP vs. Newly Created IP
A well-drafted IP assignment agreement should distinguish between background IP and newly created IP.
Background IP is intellectual property that a founder, freelancer, agency or developer already owned before working with the startup. Newly created IP is developed specifically for the startup.
This distinction matters because a developer may use pre-existing code libraries. A designer may use existing templates. A consultant may bring prior know-how. A founder may have developed a prototype before incorporation.
The agreement should answer:
- What background IP is excluded from assignment?
- Is the startup receiving a license to use background IP?
- Is that license perpetual, worldwide and sublicensable?
- What newly created IP is assigned to the startup?
- Can the contractor reuse general skills and knowledge?
- Can the contractor reuse code modules?
- Are competitor restrictions necessary?
- Are third-party rights involved?
If background IP is not addressed, disputes may arise later. The startup may believe it owns everything, while the contractor may claim that core modules were pre-existing and only licensed.
13. Open-Source Software and Third-Party Materials
IP assignment agreements should not ignore third-party materials. A developer may use open-source libraries. A designer may use stock images. A video agency may use licensed music. A branding consultant may use fonts or templates. An AI developer may use open-source models or datasets.
The assignment agreement should require disclosure of all third-party components and confirmation that the startup has the right to use them commercially.
For software, the agreement should include:
- Open-source inventory
- License names and versions
- Attribution requirements
- Restrictions on commercial use
- Source disclosure obligations
- SaaS deployment implications
- Security update obligations
- Prohibition on unauthorized code copying
For creative works, the agreement should include:
- Stock image licenses
- Font licenses
- Music licenses
- Template licenses
- AI-generated asset disclosures
- Third-party contributor releases
A startup cannot acquire more rights than the assignor actually has. Therefore, third-party material warranties are essential.
14. Formal Requirements and Registration Issues
The form and registration requirements depend on the type of IP.
For copyright-related economic rights, Turkish law requires written contracts and individual specification of the transferred rights.
For industrial property rights such as trademarks, patents and designs, assignment should be documented and recorded where appropriate. Industrial Property Code No. 6769 provides that certain legal transactions involving industrial property rights that are not entered in the registry may not be asserted against good-faith third parties.
For startups, the practical approach should be:
- Use written agreements for all IP assignments.
- Identify the IP assets clearly.
- Specify rights individually for copyright and software.
- Use notarization where required or advisable.
- Record trademark, patent, utility model and design assignments with TÜRKPATENT where relevant.
- Keep assignment documents in the company’s IP data room.
- Update internal ownership schedules after each transaction.
A signed contract hidden in email archives is not enough for investment readiness. The company should maintain organized, verifiable records.
15. Retrospective IP Assignments
Many startups discover missing IP assignments only during investment due diligence. For example, the investor asks for the software development agreement, but the startup only has invoices. Or the brand was designed by a freelancer without written transfer. Or the patentable invention was created before incorporation.
In these cases, the startup may need retrospective assignments. These documents confirm and transfer rights after the work has already been created.
A retrospective assignment should include:
- Identification of the original work or asset
- Date or period of creation
- Confirmation of the assignor’s role
- Transfer of relevant rights to the company
- Confirmation that no conflicting transfer exists
- Delivery of files and documentation
- Warranty of originality
- Disclosure of third-party materials
- Cooperation for registration or correction of records
- Release of claims where appropriate
Retrospective assignments are useful, but they depend on cooperation. If the freelancer, founder or developer refuses to sign, the startup may face legal uncertainty. This is why assignments should be signed early.
16. IP Assignment and Investor Due Diligence
Investors reviewing a Turkish startup will usually request proof that the company owns or controls its IP. They may ask for:
- Founder IP assignment agreements
- Employee IP clauses
- Developer contracts
- Freelancer and agency agreements
- Trademark certificates and assignment records
- Patent and design assignment documents
- Software repository records
- Open-source software inventory
- Domain ownership records
- Copyright and content ownership documents
- NDAs and confidentiality policies
- University or research institution agreements
- Records of disputes or infringement claims
If assignments are missing, investors may require corrective action before closing. This can delay funding and weaken the startup’s bargaining position.
A clean IP ownership structure improves credibility. It shows that the startup can commercialize its product, enforce its rights, license technology and complete a future exit.
17. Common Mistakes Startups Make
Startups in Turkey frequently make avoidable IP assignment mistakes, including:
- Assuming payment equals ownership
- Relying on verbal agreements
- Filing trademarks in a founder’s personal name
- Not assigning pre-incorporation IP to the company
- Using freelancers without written contracts
- Failing to specify copyright economic rights individually
- Not obtaining source code delivery obligations
- Ignoring background IP
- Not disclosing open-source components
- Forgetting agency subcontractors
- Leaving domain names under personal accounts
- Not recording industrial property assignments
- Failing to regulate future improvements
- Waiting until investor due diligence to fix ownership
- Using overly generic templates
These mistakes are common because early-stage startups move quickly. But speed should not eliminate basic IP discipline.
18. What Should an IP Assignment Agreement Include?
A strong IP assignment agreement for a Turkish startup should include:
- Names and legal details of the parties
- Clear definition of assigned IP
- Description of deliverables
- Transfer language
- Separate specification of copyright economic rights
- Territory and duration
- Right to modify and create derivative works
- Right to commercialize, license, sublicense and transfer
- Right to register trademarks, patents, utility models or designs
- Source code and file delivery obligations
- Assignment of future related rights where legally possible
- Moral-right-related consents to the extent permitted
- Confidentiality provisions
- Third-party material disclosure
- Open-source compliance obligations
- Warranty of ownership and originality
- Non-infringement warranty
- Further assurance and cooperation clause
- Return or deletion of materials
- Dispute resolution clause
- Governing law clause
- Signature and, where necessary, notarization or registry steps
The agreement should be adapted to the asset. A software assignment, trademark assignment, patent assignment and design assignment should not all be identical.
19. Practical Checklist for Startups in Turkey
Startups should take the following steps to secure IP ownership early:
- Identify all IP assets created before incorporation.
- Sign founder IP assignment agreements.
- Ensure trademarks are filed in the company’s name.
- Transfer personally held trademarks or domains to the company.
- Sign written contracts with all developers and agencies.
- Specify copyright economic rights individually.
- Obtain source code, editable files and technical documentation.
- Secure assignments from designers and content creators.
- Review patentable inventions and inventor assignments.
- Register or record industrial property assignments where needed.
- Separate background IP from newly created IP.
- Require disclosure of open-source and third-party materials.
- Create an IP ownership schedule.
- Store all documents in an investor-ready data room.
- Review IP ownership before fundraising, licensing or acquisition.
This checklist should be part of the startup’s legal hygiene from day one.
FAQ: IP Assignment Agreements in Turkey
What is an IP assignment agreement?
An IP assignment agreement is a contract transferring ownership or transferable economic rights in intellectual property from one party to another. For startups, it is usually used to transfer founder-created, employee-created or contractor-created IP to the company.
Does paying a freelancer mean the startup owns the IP?
Not necessarily. Payment alone may not prove full ownership. A written assignment or properly drafted license is usually necessary, especially for copyright, software, design and creative works.
Is a written agreement required for copyright assignment in Turkey?
Yes. Turkish copyright law requires contracts concerning economic rights to be in writing and the relevant rights to be specified individually.
Should founders assign pre-incorporation IP to the startup?
Yes. If founders created software, brands, designs, domains, prototypes, pitch materials or technical assets before incorporation, these should be assigned to the company.
Can trademarks be assigned in Turkey?
Yes. Industrial property rights, including trademarks, may be transferred under Industrial Property Code No. 6769, and relevant transactions should be recorded where appropriate to protect against third-party issues.
Why do investors care about IP assignments?
Investors want proof that the startup owns or controls the assets that create its value. Missing assignments create legal risk, delay funding and may reduce valuation.
Conclusion
IP assignment agreements are essential for startups in Turkey. They secure the company’s ownership over the assets that matter most: software, brands, designs, inventions, content, source code, domains, product materials and confidential business assets. Without proper assignments, a startup may appear successful commercially while remaining legally vulnerable.
The most important lesson is that IP ownership should be secured early. Founders should assign pre-incorporation assets to the company. Freelancers and agencies should sign written assignment agreements before work begins. Developers should transfer software rights clearly and deliver source code. Trademark, patent and design ownership should be recorded correctly. Confidential know-how should be protected through contract and practice.
A startup that controls its IP is easier to fund, easier to scale, easier to license and easier to sell. A startup that delays IP assignment may discover the problem only when an investor, competitor, former founder or contractor challenges ownership.
For Turkish startups, early IP assignment is not a technical legal detail. It is a core part of building a valuable, defensible and investment-ready business.
