In the ever-evolving world of innovation and technology, understanding what can be patented and what cannot be patented is one of the most crucial steps for inventors, startups, researchers, and corporations. Every great idea starts with creativity, but securing intellectual property rights requires legal precision, awareness, and a clear understanding of patent laws.
This detailed guide, presented by Prip LLC, aims to help innovators and businesses navigate the complexities of the patent system. Whether you’re designing a new machine, developing an AI algorithm, or creating a biotechnology process, knowing the line between patentable and non-patentable subject matter is essential.
Understanding the Basics: What Is a Patent?
Before diving into what can be patented and what cannot be patented, let’s clarify what a patent actually is.
A patent is an exclusive legal right granted by a government to an inventor or assignee for a limited time—typically 20 years from the filing date—to make, use, sell, and distribute an invention. In exchange, the inventor must publicly disclose the details of the invention.
Patents encourage innovation by rewarding inventors while contributing to public knowledge.
The Three Main Types of Patents
-
Utility Patents:
These protect new and useful processes, machines, manufactured items, or compositions of matter. -
Design Patents:
These cover the ornamental design or appearance of a functional item. -
Plant Patents:
These apply to newly discovered or asexually reproduced plant varieties.
Each type of patent has its own eligibility rules, which influences what can be patented and what cannot be patented.
Legal Standards That Define Patentability
Globally, patent offices such as the USPTO (United States Patent and Trademark Office), EPO (European Patent Office), and WIPO (World Intellectual Property Organization) apply specific tests to decide patent eligibility.
To qualify for patent protection, an invention must meet five major requirements:
-
Novelty – The invention must be new and not publicly disclosed anywhere in the world before the filing date.
-
Non-Obviousness (Inventive Step) – The invention must not be an obvious improvement to someone skilled in that field.
-
Utility (Industrial Applicability) – The invention must have a practical application or use.
-
Patentable Subject Matter – The invention must fit within the legal definition of patentable material.
-
Adequate Disclosure – The inventor must clearly describe the invention so that others can replicate it.
Prip LLC emphasizes that failing any one of these tests can result in rejection by the patent office—making professional patent analysis essential before filing.
What Can Be Patented?
Let’s begin with the part every inventor loves to know: what can be patented.
1. Machines and Mechanical Devices
Innovative machines, engines, tools, or devices that perform a specific function are classic examples of patentable inventions.
Examples:
-
A new type of solar-powered generator.
-
A robotic arm for manufacturing.
2. Processes and Methods
Processes that transform materials, data, or energy in a novel and useful way can be patented.
Examples:
-
A new manufacturing process for biodegradable plastic.
-
A machine-learning algorithm that enhances image recognition accuracy.
3. Compositions of Matter
Chemical compounds, pharmaceutical formulas, or new materials are patentable.
Examples:
-
A new drug formulation for treating diabetes.
-
A unique polymer with enhanced strength and heat resistance.
4. Articles of Manufacture
Objects or tools made by humans (not natural phenomena) are eligible.
Examples:
-
A new smartphone casing design.
-
A foldable electric bicycle.
5. Software (Under Certain Conditions)
While not all software can be patented, some software that offers a technical solution to a technical problem may qualify.
Examples:
-
An algorithm that controls industrial robots.
-
A data encryption process enhancing cybersecurity.
6. Biotechnology and Genetic Engineering
Genetically modified organisms (GMOs), lab-created genes, or unique biological materials can be patented if they meet novelty and utility standards.
Examples:
-
A genetically modified crop resistant to drought.
-
A lab-synthesized antibody for medical use.
7. Electrical and Electronic Systems
Innovations in electrical circuits, sensors, or digital communication systems are commonly patentable.
Examples:
-
A new type of wireless charging system.
-
An energy-efficient LED lighting circuit.
8. Industrial Applications
Processes or devices that improve industrial efficiency often receive patent protection.
This aligns with Prip LLC’s mission to support inventors and industries embracing automation, energy optimization, and manufacturing innovation.
What Cannot Be Patented?
Equally important is knowing what cannot be patented. Not all brilliant ideas or discoveries qualify for patent protection, even if they are new or useful.
1. Laws of Nature and Natural Phenomena
Anything that exists naturally or is discovered (not created) cannot be patented.
Examples:
-
The law of gravity.
-
Naturally occurring minerals or elements.
2. Abstract Ideas
Concepts or mental processes that are not tied to a specific practical application cannot be patented.
Examples:
-
Mathematical formulas.
-
Abstract business models without technological implementation.
3. Scientific Principles or Theories
Theories or hypotheses explaining natural phenomena are excluded.
Example:
-
Einstein’s Theory of Relativity.
4. Artistic Creations or Aesthetic Designs
Creative works such as music, literature, and art are protected by copyright, not patents.
Examples:
-
A song composition.
-
A painting or sculpture.
5. Human Organisms and Medical Procedures
Ethical laws prohibit patenting human beings or methods for performing surgeries on humans.
Examples:
-
A human embryo.
-
A surgical technique for organ transplantation.
6. Software Without Technical Effect
Simple data processing or automation of mental tasks without a technical innovation cannot be patented.
7. Business Methods
In most jurisdictions, business models or marketing techniques are not patentable unless tied to a technical process.
Example:
-
A new financial transaction model without a technological component.
8. Illegal or Immoral Inventions
Any invention promoting illegal activity or contrary to public morality is rejected.
Examples:
-
A new type of counterfeit currency machine.
-
A system for unauthorized surveillance.
Prip LLC helps inventors pre-screen their inventions against these exclusions before filing, reducing the risk of rejection and wasted expenses.
The Role of Patent Attorneys and Legal Experts
Navigating the complex boundaries of what can be patented and what cannot be patented often requires professional legal advice.
Patent lawyers and firms like Prip LLC specialize in:
-
Conducting prior art searches.
-
Drafting strong, defensible patent claims.
-
Handling office actions and rejections.
-
Advising on international patent filings (PCT).
Hiring experts ensures that your application aligns with legal requirements and maximizes protection.
Importance of Global Jurisdictions
Patent eligibility criteria vary between countries. For instance:
-
United States (USPTO): Allows some software and business method patents if they demonstrate technological improvement.
-
European Union (EPO): Excludes purely software-based inventions unless they have a technical effect.
-
Japan and Korea: Favor patents with strong industrial application.
If your business operates internationally, Prip LLC can guide you through cross-border patent protection strategies that meet multiple jurisdictional standards.
