Introduction
One of the most groundbreaking developments in modern biotechnology is the advent of CRISPR-Cas9 gene-editing technology. This technique allows for precise, rapid, and cost-effective modification of genetic material in living organisms, unlocking transformative possibilities in areas such as rare genetic diseases, cancer treatments, and agricultural biotechnology.
However, the commercialization and clinical use of CRISPR technology have also triggered patent disputes, debates over the scope of intellectual property rights, and ethical-legal controversies. This article explores the patentabilityof CRISPR-based inventions, the legal nature of gene therapies, and the balance between public interest and private innovation in the context of biotechnology law.
1. Definition and Applications of CRISPR Technology
CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) is derived from a natural immune mechanism used by bacteria to defend against viruses. When combined with the Cas9 enzyme, it enables the targeting, cutting, and editing of DNA sequences.
Key application areas include:
- Human gene therapies (e.g., sickle cell disease, beta-thalassemia),
- Cancer immunotherapies,
- Agricultural biotechnology (e.g., stress-resistant crops),
- Preclinical research using animal models.
2. CRISPR and Patent Law: The First Disputes
One of the earliest and most high-profile legal battles over CRISPR was between the Broad Institute (MIT-Harvard)and the University of California, Berkeley. The dispute centered around who first invented the technology, its specific applications, and which technical elements are eligible for patent protection.
Patentable Elements:
- Laboratory-engineered variants of CRISPR systems,
- Specific genome-targeting mechanisms using Cas9,
- Tools and compositions for therapeutic applications.
Non-Patentable Elements:
- Naturally occurring genetic sequences,
- Naturally existing proteins or enzymes,
- Discoveries of natural biological processes (unless technically modified).
3. Patent Protection under Turkish and International Law
In Turkey, biotechnological inventions like CRISPR are regulated by the Industrial Property Law No. 6769. According to the law:
Article 82/2(b): “Diagnostic and therapeutic methods practiced on the human or animal body are not patentable.”
However, this restriction applies to methods, not to the products or tools used in such methods. If these tools are novel, involve an inventive step, and are industrially applicable, they may qualify for patent protection.
Under international frameworks:
- The TRIPS Agreement (Article 27) mandates that patents be available for all technologies without discrimination, but allows public health exceptions.
- The European Patent Convention (EPC) limits the patentability of human genetic material.
For example, Article 53(a) EPC excludes inventions “contrary to public order or morality.”
4. Gene Therapies: Legal and Ethical Boundaries
CRISPR-based gene therapies, especially those involving human embryos or germline editing, raise serious ethical and legal concerns due to their heritable nature.
Relevant Ethical and Legal Principles:
- Article 13 of the Oviedo Convention permits genetic interventions only for preventive, diagnostic, or therapeutic purposes—not for enhancement or eugenic aims.
- National clinical trial regulations in Turkey require informed consent, ethics committee approval, and scientific justification for human subject research.
- Under KVKK (Turkish Data Protection Law), genetic data is classified as sensitive personal data, and its processing is strictly regulated.
5. Balancing Public Interest and Private Rights: Compulsory Licensing and Exceptions
Patent protection on CRISPR-based therapeutics may conflict with public health needs. Legal systems often provide tools to restrict or override patent rights in such cases.
Key mechanisms include:
- Compulsory licenses under Articles 129–132 of the Industrial Property Law, where public interest is at stake.
- Research exemption, allowing non-commercial academic or clinical use without constituting patent infringement.
- Public data sharing principles in bioethics, encouraging open science and transparency in CRISPR research.
Conclusion
CRISPR technology holds enormous potential in transforming healthcare, agriculture, and genetic science. Yet the legal regulation of its commercialization and application must carefully address the delicate balance between private intellectual property rights and public welfare.
While patent law incentivizes innovation, it must:
- Avoid restricting the free flow of genetic information,
- Not hinder access to life-saving treatments,
- Be flexible in emergencies through mechanisms such as compulsory licenses.
Therefore, the legal treatment of CRISPR-based inventions must go beyond the scope of patent law and be evaluated in light of bioethics, human rights, data protection, and health policy frameworks.
