Utility models offer a practical and relatively fast route to protect technical innovations in Türkiye. For many applicants, especially those seeking quicker and more cost-effective protection than patents, utility models are an attractive alternative.

This guide walks through the essentials: what can be protected, what cannot, and how the process works in practice.

What Is a Utility Model?

A utility model is a form of intellectual property right that protects inventions. In Türkiye, it requires:

  • Novelty
  • Industrial applicability

Unlike patents, inventive step is not required. This is the key difference and often the main reason applicants choose this route.

What Cannot Be Protected?

Not everything qualifies as an invention under Turkish law. The following are excluded from protection:

  • Discoveries, scientific theories, and mathematical methods
  • Business methods, game rules, and mental activities
  • Computer programs
  • Artistic, literary, and aesthetic creations
  • Presentation of information

These are not considered “inventions” in the first place.

Inventions Specifically Excluded from Utility Models

Even if something is an invention, it may still fall outside the scope of utility model protection in Türkiye.

The following cannot be protected:

  • Chemical and biological substances and processes
  • Pharmaceutical products and methods
  • Biotechnological inventions
  • Medical treatment, diagnostic, and surgical methods
  • Essentially biological processes for plants and animals
  • Human cloning and genetic modification processes
  • Inventions contrary to public order or morality

In short, utility models are mainly suitable for mechanical and practical innovations, not life sciences.

Filing Requirements

Filing a utility model application in Türkiye is relatively straightforward. The following are required:

  • Applicant details
  • Inventor details
  • Description, claims, abstract, and drawings

Search Requirement and Timeline

Unlike some jurisdictions, Türkiye requires a prior art search for utility models.

  • The search request can be filed at the time of application
  • If not, it must be filed within 2 months after formal compliance notification
  • The search fee must also be paid within this period

Failure to meet this deadline results in the application being deemed withdrawn.

Publication and Third-Party Involvement

The search report is published together with the application.

Within 3 months from publication:

  • Applicants can file objections
  • Third parties can submit observations

This stage allows early scrutiny of the application before grant.

Grant Procedure

After the search stage, the Turkish Patent and Trademark Office evaluates the application.

Possible outcomes:

  • If requirements are met → Utility model is granted
  • If amendments are needed → applicant is given 2 months to respond
  • If deficiencies remain → application is deemed withdrawn
  • If requirements are not met → application is refused

There is no opposition procedure after grant. Any challenge must be brought before the courts.

Grace Period

Türkiye provides a 12-month grace period.

Disclosures made:

  • By the inventor, or
  • By third parties deriving from the inventor

within 12 months before filing do not destroy novelty.

This is particularly useful for early-stage disclosures or exhibitions.

Protection Term and Maintenance

  • Protection lasts 10 years from the filing date
  • Annual fees are due starting from the 3rd year

Failure to pay annuities results in loss of rights.

Conversion Options

Applicants have some flexibility:

  • A utility model can be converted into a patent application within 3 months after the search report
  • PCT applications can enter Türkiye directly as utility models

However:

  • Double protection (patent + utility model for the same invention) is not allowed
  • It is not possible to derive a utility model from a European patent application (except very limited EPC Article 77 scenarios)

Strategic Considerations

Utility models are particularly useful when:

  • Speed is important
  • The invention may not meet inventive step
  • The technology is mechanical or incremental

However, applicants should keep in mind:

  • No substantive examination like patents
  • No post-grant opposition
  • Vulnerability to invalidation actions

Final Thoughts

Utility models in Türkiye provide a fast and efficient way to secure protection, especially for practical inventions.

That said, choosing between a patent and a utility model is a strategic decision. The right approach depends on the nature of the invention, the market timeline, and enforcement expectations.

A well-planned filing strategy can make a significant difference in both protection scope and long-term value.
