Understanding what cannot be patented in intellectual property rights is just as critical as knowing what can be. At Prip LLC, inventors, businesses, and creators must clearly grasp patent eligibility to avoid wasting time, money, and resources. While patents are designed to protect unique inventions, there are clear boundaries defined by patent law worldwide. This guide deeply explores the categories, limitations, and examples of subject matter that fall outside patentability.
Understanding Patent Eligibility
A patent grants inventors exclusive rights to their inventions for a specific period, usually 20 years from the filing date. However, not everything is patentable. Patent law explicitly defines what cannot be patented, to maintain a balance between innovation and the public domain.
Globally, patent offices like the USPTO (United States Patent and Trademark Office), EPO (European Patent Office), and others outline criteria for patentability, which include:
- Novelty – The invention must be new.
- Non-obviousness – It cannot be something obvious to experts in the field.
- Utility – The invention must have a practical purpose.
If any of these are missing, the invention is deemed not patentable.
Key Categories of What Cannot Be Patented
1. Laws of Nature and Natural Phenomena
Discoveries such as gravity, DNA sequences found in nature, or the orbit of planets are excluded. While one can patent a process or product using natural phenomena, they remain unpatentable.
2. Abstract Ideas and Mathematical Formulas
Abstract concepts, pure mathematics, or algorithms without practical application cannot be patented. For example, a raw formula like E=mc² is excluded. However, if a formula is embedded in a novel software solution, it may be considered.
3. Mental Processes
Processes that can be performed entirely in the human mind or require human thought, without any technical or practical application, are considered non-patentable.
4. Scientific Theories and Methods of Teaching
Theories like the theory of relativity or educational methodologies are not patentable. They are considered public knowledge intended for free academic and societal development.
5. Medical Procedures and Treatment Methods
In many countries, medical procedures such as surgical, therapy, or diagnostic methods are excluded from patent protection. However, medical devices used in these processes may be patentable.
6. Naturally Occurring Substances
Plants, minerals, or organisms existing naturally cannot be patented in their natural form. For instance, a plant species discovered in the wild is excluded. However, genetically modified versions of organisms may be eligible.
7. Works Against Public Morality or Order
Any invention contrary to public order, safety, or morality is excluded. For example, devices designed solely for illegal activities cannot receive patent rights.
8. Artistic Creations and Literary Works
Art, music, and literature are protected under copyright law, not patent law. A novel painting style or a new book cannot be patented.
9. Schemes, Rules, and Methods for Playing Games
Gaming rules, organizational methods, or schemes for doing business are often excluded. However, a new gaming device or innovative software-based gaming solution could be patentable.
10. Business Methods and Pure Software
While some jurisdictions allow business method patents, the USPTO restricts purely abstract methods. For instance, a business model explaining “how to sell faster” cannot be patented, but a technological system that automates sales might qualify.
Global Perspectives on What Cannot Be Patented
Different countries impose their own limitations:
- United States: Excludes natural phenomena, abstract ideas, and laws of nature.
- European Union: Excludes discoveries, aesthetic creations, and methods for mental acts.
- India: Excludes business methods, mathematical methods, and algorithms.
- China: Prohibits inventions that harm public interests or violate social ethics.
At Prip LLC, we specialize in helping clients understand these jurisdictional nuances before pursuing international patents.
Detailed Examples of What Cannot Be Patented
- Gravity – A universal law of nature.
- A new mathematical equation – Without a practical application.
- Surgical stitching method – Considered a medical practice.
- A wildflower is naturally occurring and not human-made.
- Rules for chess – Abstract and mental act.
- A poem or painting – Covered by copyright.
- Lottery system – Excluded due to gambling laws.
Why Knowing What Cannot Be Patented Matters
Understanding what falls outside patentability is vital to avoid:
- Legal costs – Filing patents that will be rejected.
- Wasted time – Preparing applications for ineligible inventions.
- Lost opportunities – Missing focus on patentable improvements.
At Prip LLC, we guide inventors in focusing resources on ideas with strong chances of patent approval.
Pros and Cons of Knowing What Cannot Be Patented

FAQs on What Cannot Be Patented
Q1: Can software be patented?
In some jurisdictions, software can be patented if it provides a technical solution to a technical problem. However, pure algorithms or abstract code cannot be patented without a practical application.
Q2: Can I patent my idea for a business model?
No, a business model is not patentable by itself. To be considered, it must involve a novel technological process or system.
Q3: Are recipes patentable?
Recipes are generally not patentable if they are only combinations of known ingredients. However, a novel food processing method or unique chemical reaction used in a recipe may qualify.
Q4: Can a medical treatment be patented?
In the U.S., some medical methods may be patentable, but in many countries, surgical and therapeutic methods are excluded. Devices and pharmaceuticals, however, are usually eligible.
Q5: Can I patent a discovery like a plant or mineral?
No. Naturally occurring discoveries cannot be patented. However, if you develop a genetically modified organism (GMO) or a synthetic version, it may be patentable.
Q6: Is artificial intelligence patentable?
AI itself as a concept is not patentable. However, specific AI applications, models, and systems with technical novelty can be.
Q7: What should I do if I am unsure if my invention is patentable?
Consulting professionals like Prip LLC is the best approach. Patent attorneys can analyze your invention, conduct a patent search, and advise you on eligibility.
