Have you ever wondered how long a patent lasts and what it means for inventors and businesses? A patent is a legal document that grants exclusive rights to an inventor for their invention. However, these rights are not indefinite, and patents do have an expiration date.
In this article, we will explore the different types of patents and their respective expiration dates. We will also discuss the significance of patent duration and how it affects innovation and competition in various industries. So, whether you are an innovator, entrepreneur, or simply curious about patent laws, keep reading to learn more about the duration of patents.
How Long Do Patents Last?
A patent is a legal document that grants the patent holder exclusive rights to an invention. This means that no one else can make, use, or sell the invention without the permission of the patent holder. However, these exclusive rights do not last forever. Every patent has an expiration date, after which the invention can be freely used by anyone.
Patent Duration
The length of time that a patent lasts depends on the type of patent that is granted. In general, there are three types of patents: utility patents, design patents, and plant patents.
Utility patents are the most common type of patent. They are granted for new and useful inventions or discoveries, and they last for 20 years from the date of filing. This means that the patent holder has exclusive rights to the invention for 20 years from the date that they filed the patent application.
Design patents, on the other hand, are granted for new and original designs for articles of manufacture. They last for 15 years from the date of grant. This means that the patent holder has exclusive rights to the design for 15 years from the date that the patent was granted.
Plant patents are granted for new and distinct varieties of plants that have been asexually reproduced. They last for 20 years from the date of filing. This means that the patent holder has exclusive rights to the plant variety for 20 years from the date that they filed the patent application.
Benefits of Patents
Patents provide several benefits to inventors and businesses. First and foremost, they give the patent holder exclusive rights to their invention, which means that no one else can make, use, or sell the invention without their permission. This gives the patent holder a competitive advantage and allows them to profit from their invention.
Patents also encourage innovation by providing a financial incentive for inventors to create new and useful inventions. By granting exclusive rights to the inventor, patents allow them to recoup their investment in research and development and make a profit from their invention.
Furthermore, patents help to protect intellectual property and prevent others from stealing or copying an inventor’s idea. This can be especially important for businesses that rely on their intellectual property to stay competitive.
Patent Vs. Trademark and Copyright
While patents protect inventions and discoveries, trademarks and copyrights protect other types of intellectual property. Trademarks are used to protect logos, brand names, and other identifying marks, while copyrights are used to protect creative works like books, music, and artwork.
Unlike patents, trademarks and copyrights do not have an expiration date. Instead, they last for as long as they are in use or until the copyright or trademark owner decides to abandon them.
Patent Duration Extension
In some cases, it is possible to extend the duration of a patent beyond its initial expiration date. This is called a patent term extension, and it is granted to inventors who have experienced delays in the regulatory approval process for their invention.
To qualify for a patent term extension, the inventor must demonstrate that the regulatory delay caused them to lose part of the 20-year term of their patent. If approved, the extension will add the lost time back onto the patent term, giving the inventor more time to profit from their invention.
Patent Expiration and the Public Domain
When a patent expires, the invention enters the public domain. This means that anyone can use, make, or sell the invention without the permission of the patent holder. This can be beneficial for consumers, as it allows for more competition and lower prices.
However, it can also be challenging for businesses that rely on their intellectual property to stay competitive. For this reason, many companies will continue to invest in research and development to create new and innovative products that can be patented and protected.
Conclusion
In conclusion, the length of time that a patent lasts depends on the type of patent that is granted. Utility patents last for 20 years from the date of filing, design patents last for 15 years from the date of grant, and plant patents last for 20 years from the date of filing.
Patents provide several benefits to inventors and businesses, including exclusive rights to their inventions, a financial incentive for innovation, and protection of intellectual property. However, patents do have an expiration date, after which the invention enters the public domain.
Overall, patents play a crucial role in promoting innovation and protecting intellectual property, and understanding how long they last is essential for anyone interested in inventing or investing in new products.

Frequently Asked Questions
What is a patent?
A patent is a form of intellectual property that gives the person who holds the patent the right to prevent others from making, using, or selling an invention for a certain period of time. The invention must be novel, non-obvious, and useful to be eligible for a patent.
How long do utility patents last?
Utility patents, which cover machines, processes, and compositions of matter, last for 20 years from the date of filing. However, the patent owner must pay maintenance fees to keep the patent in force. The maintenance fees are due at 3.5, 7.5, and 11.5 years after the patent is granted.
If the patent owner does not pay the maintenance fee, the patent will expire and become part of the public domain, meaning anyone can use the invention without permission or compensation to the patent owner.
How long do design patents last?
Design patents, which cover ornamental designs for a useful article, last for 15 years from the date of grant. Unlike utility patents, design patents do not require maintenance fees to stay in force. After the design patent expires, the design becomes part of the public domain.
How long do plant patents last?
Plant patents, which cover asexually reproduced plants, last for 20 years from the date of filing. Like utility patents, plant patents require maintenance fees to stay in force. The maintenance fees are due at 3.5, 7.5, and 11.5 years after the patent is granted.
If the patent owner does not pay the maintenance fee, the patent will expire and become part of the public domain.
Can a patent be extended beyond its original expiration date?
In certain circumstances, a patent may be extended beyond its original expiration date. For example, if the patent owner can prove that they were unable to commercially exploit the invention due to regulatory delays, they may be granted a patent term extension. However, such extensions are rare and granted on a case-by-case basis.
It’s important to note that patent extensions are not available for design patents or plant patents.
How Long Are Patents Good For? When do They Expire? (Patent Continuations and More.)
In conclusion, the duration of a patent is an important aspect to consider for any inventor or business owner. Patents can last for up to 20 years from the date of filing, but this can vary depending on the type and country of the patent.
It is crucial to understand the expiration date of your patent to ensure that your invention is protected and to avoid any legal issues. Once a patent expires, anyone can use or sell the invention without permission, which can cause a significant loss in revenue for the patent holder.
Therefore, it is recommended to stay up-to-date with patent laws and regulations in your country and seek professional advice if needed. Proper patent management can provide long-term benefits and protection for your intellectual property.
