Who owns the intellectual property rights in software projects?

Intellectual Property Rights in Software Development Projects

When you decide to develop a software project, the first question that comes to mind for many business owners is: "Who will own this code?" This question is extremely important for both the client and the developer. Intellectual property rights play a crucial role in the software world, protecting investment and ensuring freedom of future use. Having been in software development for 25 years and delivering hundreds of projects, I've seen just how critical this issue is.

Software intellectual property rights should generally be clearly defined in the contract. Otherwise, legal uncertainty, disputes, and costly lawsuits may arise. In this article, I explain who owns what rights, the legal framework, and the realities of practice.

What does Intellectual Property Rights Mean in Legal Terms?

In Turkish law, intellectual and industrial property rights are protected by the Intellectual and Industrial Property Law. Software code is automatically protected under copyright as an original work. This means that copyright arises from the moment the software is developed, without requiring any registration or formal process.

By law, the person who creates the work (i.e., the programmer) is the primary owner. However, this right can be transferred in an employer-employee relationship or through a contractual agreement. Contract documents and written agreements are therefore crucial.

Common Patterns: Who Could They Belong To?

1. Full Assignment to the Client

In this model, the developer completely transfers ownership of all code, design, and associated documentation to the client. The client can modify the code as they see fit, give it to someone else, use it commercially, or even reuse it in another project.

This is the safest way for business owners because you own the software without any restrictions. Most of the large e-commerce or custom software projects I've worked on in Alanya and Antalya are structured this way.

2. Rights Shared Between Developer and Customer

Some projects are structured so that both parties have specific rights. For example, the client acquires commercial usage rights, while the developer may reserve the right to use the portfolio presentation or general methodology.

This model is rare and requires clearly defined boundaries. I wouldn't recommend it because it creates uncertainty.

3. Developer-Owned Licensing Model

The developer retains ownership of the code, granting the client a license to use it for a specific purpose (e.g., solely within their own business). The client cannot modify or transfer the code; they can only use it for their own needs.

This model is common in proprietary software SaaS services. The developer retains control of the codebase while the customer's needs are met.

What should be clearly stated in the contract?

To avoid legal disputes, the software development agreement should clearly state the following:

• Property Transfer Date: When will the rights be transferred? Upon completion of the project or receipt of payment?
• What elements does it include? Just the final code, design files, database structure, or documentation?
• Pre-existing Code: What can the developer say about libraries, open-source tools, or templates used in previous projects?
• Dependencies and Libraries: If the software relies on external libraries (npm packages, frameworks), what can be said about them?
• Support and Signature Rights: After a customer modifies the code, is the developer responsible for it?
• Confidentiality Obligation: Can the developer showcase the client project as an example/portfolio?

The Shortage of Open Source and Third-Party Libraries

Most software projects are not written from scratch. They use open-source tools such as React, Node.js, database libraries, etc. Many of these tools have their own licenses (such as MIT, GPL, Apache 2.0).

The contract should clearly state which open-source components are used and their licensing terms. Software licensed under the GPL, in particular, may include conditions such as publicly available code. Omitting such details could lead to problems for the customer later on.

Application in Software Projects in Alanya and Antalya

Locally, most software development businesses in Alanya sign full ownership transfer agreements with their clients. This is because Alanya is a tourist area, and small to medium-sized businesses such as hotels, restaurants, and real estate want their software to be entirely their own.

However, in projects where large agencies work with companies that provide infrastructure support, code-sharing models are more complex. To understand the costs involved in corporate website development , it is necessary to know the intellectual property rights structure.

Acquired Projects and Code Ownership

Sometimes, you may want to take over a project that was developed by another developer or agency. In this case, clearly verify ownership of the code written by the original developer. Without written ownership documentation, the original developer can sue at any time.

Businesses that approach me sometimes deal with these kinds of inheritance projects. A client who takes over without a contract may face legal risks.

A Good Practice: Written Contract Requirement

Before starting the software project, I recommend taking the following steps:

• Review the contract template with a legal advisor (especially for large projects).
• Record the transfer of ownership, its duration, scope, and exceptions in writing.
• Prepare a list of open-source components and provide it to the client.
• When the project is handed over, deliver all documentation, passwords, server access, and database information using a checklist.
• Archive the copy of the contract signed by all parties.

Conclusion

In software projects, intellectual property rights are critical for both protecting your business and keeping the developer fair. The answer to the question "Who owns it?" should always be included in the contract clauses.

Although the legal framework in Türkiye is clear, I have seen in practice that lawsuits can arise when there are no written agreements. When working with clients in Alanya, Antalya, and the surrounding region, I always emphasize this point: your software is your asset; protect that asset with written documentation.
