An Introduction to what is a patent
A patent is a government-granted right that gives an inventor exclusive control over a new and useful invention for a limited period of time. In exchange, the inventor must publicly disclose how the invention works.
Patents are a foundational part of intellectual property law. They allow individuals and companies to protect innovation, attract investment, and prevent others from copying or profiting from their work without permission.
But they are not always the best tool for every kind of innovation. Understanding how patents work is essential for choosing the right protection strategy.
What does a patent protect?
A patent protects the way something works or how it is made. This can include:
- A physical product, such as a new type of medical device
- A process or method, like a manufacturing technique or software workflow
- A composition of matter, such as a new chemical formula or pharmaceutical compound
- A machine or system, such as an engine or automated system
To qualify for patent protection, an invention must be:
- Novel: It must be new and not already publicly known
- Non-obvious: It must not be an obvious improvement or change to something already known
- Useful: It must have a practical application
How long does a patent last?
Most patents last 20 years from the date of filing. During this time, the patent holder has the exclusive right to make, use, sell, and license the invention.
After the patent expires, the invention enters the public domain. Anyone can use it freely without seeking permission or paying royalties.
What is disclosed in a patent?
To obtain a patent, the inventor must submit a detailed description of how the invention works. This disclosure is published publicly. Anyone can search, read, and study the contents of a patent.
That disclosure is part of the tradeoff. In return for time-limited exclusivity, the inventor gives up secrecy. For this reason, patents are not always the best choice for protecting sensitive or proprietary information.
When is a patent the right tool?
Patents are effective when you want to:
- Prevent others from creating or selling a specific invention
- License or sell a technology in a transparent way
- Attract funding by showing a strong IP portfolio
- Establish ownership in a crowded or competitive market
However, they may not be ideal when:
- The invention can be easily reverse engineered from the product
- The value lies in know-how or internal processes that are not disclosed to the public
- The invention will evolve quickly and filing updates would be expensive
- Disclosure would give competitors a roadmap to replicate or work around your idea
In these situations, companies may choose to rely on trade secrets instead.
Key takeaways
- A patent gives exclusive rights to an invention in exchange for public disclosure
- It protects how something works, not just how it looks or is branded
- Patent rights typically last 20 years
- Public disclosure makes patents unsuitable for certain types of innovation
- In some cases, trade secret protection is a better fit
How Tangibly can help
Many companies patent too quickly or without understanding the tradeoffs. Others skip protection entirely and leave valuable innovation exposed.
Tangibly helps companies design smarter IP strategies by identifying what should be patented, what should be protected as a trade secret, and where the two approaches can work together.
Our platform combines legal expertise and AI tools to help you assess risk, protect sensitive know-how, and build a strong foundation for long-term value.
