Term and Introduction: Biotechnological Inventions
Biotechnological Inventions are innovations in the field of biotechnology that are of a technical nature and concern novel processes, products, or substances derived from biological materials. In legal terms, the concept refers to the specific application of biological processes and systems to solve technical problems, particularly in connection with patents and intellectual property. Biotechnological inventions play a central role in medicine, pharmaceuticals, agriculture, and environmental technology.
Legal Framework for Biotechnological Inventions
Patent Protection for Biotechnological Inventions
General Requirements
Under German Patent Law (§ 1 Patentgesetz, PatG) as well as in the European context (Art. 52 et seq. European Patent Convention, EPC), biotechnological inventions can in principle be eligible for protection if they meet the following requirements:
- Novelty: The invention must not form part of the state of the art.
- Inventive Step: The invention must not be obvious to a person skilled in the art in light of the state of the art.
- Industrial Applicability: The invention must be capable of being made or used in any field of industry.
Specific Provisions in Patent Law
With EU Directive 98/44/EC (“Biotechnology Directive”) and its implementation into German law (§§ 1a to 1c PatG), the specific legal framework for biotechnological inventions was created. In particular, the following aspects must be taken into account:
- Patentable are microbiological or other technical processes and products derived therefrom as well as genetically modified organisms.
- An isolated component or a component separated from the human or animal body by a technical process, including the sequence or partial sequence of a gene, can also be patentable if industrial applicability is demonstrated.
- Modifications to the human body at the embryonic developmental stages, including the germline, are generally excluded from patent protection.
Non-patentable Biotechnological Inventions
Pursuant to § 2a PatG and Art. 53 EPC, certain biotechnological processes are not patentable. These specifically include:
- Procedures for cloning human beings.
- Procedures for modifying the genetic identity of the human germline.
- Use of human embryos for industrial or commercial purposes.
- Procedures for modifying the genetic identity of animals that cause significant suffering without substantial medical benefit.
- Plant varieties or animal breeds as well as essentially biological processes for the breeding of plants and animals (except for microbiological processes).
Handling Biological Material and Gene Sequences
The patenting of inventions involving biological materials or gene sequences is subject to special legal requirements. Patent protection requires demonstrating how the material is obtained and how it is technically exploited. In addition, claims regarding the function and technical effect of the isolated sequence must be clearly defined. Pure discoveries, such as the mere identification of a natural gene sequence without technical application, are not patentable.
International Regulations and Distinctions
Biotechnological Inventions in International Patent Law
Numerous countries base the design of their biopatent law on the provisions of the TRIPS Agreement (Trade-Related Aspects of Intellectual Property Rights). Accordingly, WTO member states must generally provide protection for biotechnological inventions, although exceptions are permitted for plants and animals, provided that plant varieties are protected by a specific plant variety protection system.
Distinction from Non-technical “Discoveries”
Unlike a purely scientific discovery (such as finding a natural substance or gene), only the technical application of this discovery as an invention is patentable. Applicability in terms of a technical teaching is decisive for classification as a biotechnological invention.
Further Legal Aspects of Biotechnological Inventions
Dealing with Ethical and Moral Boundaries
Biotechnological patents are subject to special ethical and moral considerations. Under German and European patent law, inventions are not patentable if their exploitation would be contrary to public order or morality. Internationally, differing ethical assessments are taken into account, for example in the patenting of stem cells or the application of CRISPR technologies.
Scope of Protection and Limitations of the Patent
A granted patent confers the exclusive right to make, use, and market the respective biotechnological invention (§ 9 PatG, Art. 64 EPC). At the same time, limitations exist through compulsory licenses, the exhaustion principle, and statutory exceptions, for example for scientific research (§§ 11 Nos. 2 and 2a PatG).
Relationship to Other Intellectual Property Rights
In addition to patent protection, biotechnological knowledge can also be protected by other intellectual property rights such as plant variety protection (Regulation (EC) No. 2100/94 on Community plant variety rights), utility model law, and the supplementary protection certificate for pharmaceuticals and plant protection products.
Practical Examples and Case Law
Significant Decisions
Court decisions, particularly of the European Patent Office and the Federal Court of Justice, continually clarify the interpretation of patent law provisions for biotechnological inventions. Leading case law concerns, among other issues, the scope of protection for gene sequences, the admissibility of patents on stem cells, and the distinction of patentable biotechnological processes.
Summary
Biotechnological inventions form a legally intensive field in which technological progress, ethical perception, and legal regulations are closely interlinked. The protection of such inventions is primarily governed by patent law, shaped by national, European, and international standards. Key requirements are novelty, inventive step, and industrial applicability. Special exceptions and limitations are implemented to protect public interest, ethical principles, and free research.

Frequently Asked Questions
What are the requirements for the patentability of biotechnological inventions?
Biotechnological inventions are generally patentable if they meet the general requirements for patentability, such as novelty, inventive step, and industrial applicability. In addition, specific requirements exist in patent law, especially in the German and European context. Biotechnological inventions must not violate public order or morality (see § 2 Patent Law, Art. 53 ECHR). Discoveries, for example the mere finding of naturally occurring genes or proteins without technical novelty, are not patentable. Inventions relating to plant or animal breeds as well as essentially biological processes for the breeding of plants or animals are excluded from patent protection (§ 2a PatG, Art. 53(b) EPC); microbiological processes, on the other hand, can be patentable. The Biotechnology Directive (Directive 98/44/EC) also requires sufficient disclosure to enable a person skilled in the art to implement the technical teaching. Particularly in the biotechnological field, the submission of a biological material sample—especially if the material is capable of being deposited—is of great importance.
To what extent are human genes and genetic sequences patentable?
As a rule, individual human genes or gene sequences as such are not patentable according to § 1 para. 2(a) PatG, as well as under the Biotechnology Directive and its implementation into German law, if only their discovery is claimed. However, gene sequences are patentable if they possess a practical, industrial application and are adequately described technically, for example the use of a gene sequence for the production of a specific protein by means of a technical process. An isolated gene fragment may therefore be patented if its function is concretely described and a technical application is provided. Purely diagnostic, therapeutic or surgical methods on the human or animal body remain excluded from patent protection. Additionally, patents on sequences may not monopolize the entire natural range of functions, but only the specifically described function and use.
What alternative forms of protection exist for biotechnological inventions?
In addition to patent protection, forms of protection such as utility model protection are available, although this is excluded in Germany for processes and thus does not apply to many biotechnological procedures. Plant variety rights according to the Plant Variety Protection Act are especially important for new plant varieties and are often linked to biotechnological developments in plant breeding. To protect trade secrets, especially if disclosure in the patent procedure is not desired, know-how can be safeguarded by confidentiality agreements and according to the Trade Secrets Act (GeschGehG). In addition, specific contractual arrangements, such as Material Transfer Agreements (MTAs), can be used to protect biotechnological materials. Copyright, on the other hand, is only applicable in exceptional cases (e.g. for software used to analyze biotechnological procedures).
Are there ethical limits to the patenting of biotechnological inventions?
Yes, ethical boundaries are of central importance in biotechnological patent law. Inventions are excluded from patenting under § 2 para. 1 No. 1 PatG and Art. 53(a) EPC if their exploitation would contravene public order or morality. This applies in particular to processes for cloning humans, the use of human embryos for industrial or commercial purposes, as well as modifications of the genetic material of the human germline (§ 2a paras. 1 and 2 PatG). Furthermore, under the Biotechnology Directive, patenting processes is prohibited if their sole purpose is to modify the sex of animals, or to create animals and plants in which suffering is caused without significant medical benefit in order to improve humans, animals, or plants.
How is the scope of protection of a patent for biotechnological inventions determined?
The scope of protection of a biotechnological patent primarily results from the patent claims, i.e. the legally relevant scope of protection as defined in the patent application. In biotechnology, the extent of product claims (e.g. to isolated DNA sequences or proteins) and process claims is particularly relevant. Product protection also extends to all items directly produced by the protected process (§ 9a PatG). For patentable inventions regarding microbiological materials, it is also important to note that protection applies to subsequent generations resulting from propagation and multiplication. The precise interpretation is based on national case law and European legislation, especially the protocol on the interpretation of Art. 69 EPC. Mandatory exceptions can limit protection, such as the breeder’s exemption in plant protection law.
What disclosure obligations exist in the context of applying for biotechnological patents?
The invention must be disclosed clearly and completely enough for a person skilled in the art to carry it out (see § 34 para. 4 PatG, Art. 83 EPC). In the case of biotechnological inventions, this requirement is often only met if the biological material was not publicly available on the filing date and cannot otherwise be described. In such cases, the material must be deposited with a recognized depositary institution (such as DSMZ, ATCC) according to the Budapest Treaty. The deposit number, as well as all relevant information on propagation and handling, must be specified in the application. These disclosure obligations ensure that, in return for the patent monopoly, the further development and use of similar technologies by others is possible after expiry of the patent.
What applies to biotechnological inventions in the international context?
In the international context, the provisions of the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS), the Biotechnology Directive (98/44/EC), and the European Patent Convention (EPC) are decisive. These instruments ensure extensive harmonization of requirements and scope of protection among member states but also involve special rules: for example, national laws may provide stricter limitations in ethically sensitive areas such as embryo research. For applications with effect in several countries, the PCT procedure (Patent Cooperation Treaty) is relevant, which allows centralized filing with later national or regional phases. Differences exist, for example, in the interpretation of industrial applicability and the patentability of certain biotechnological processes. Thus, the recognition and scope of patent protection can differ internationally; detailed knowledge of the respective legal situation is therefore essential.
