Patent Attorney and Founder
Hey everyone! Today, I’m answering a common question: When do patents enter the public domain?
I’m JD Houvener, a patent attorney and founder of Bold Patents Law Firm. Over the past decade, I’ve helped thousands of inventors protect their ideas, with more than 300 patents granted. Let’s break this down in a simple way.
What Does “Public Domain” Mean?
When a patent enters the public domain, anyone can use, make, or sell that invention without worrying about infringement. Think of it as the point where the patent’s exclusive protection expires. Once it’s expired, it’s free for anyone to use.
How Long Do Patents Last?
The duration depends on the type of patent:
- Utility Patents: 20 years.
- Design Patents: 15 years.
After this period, the invention becomes public property.
But There’s a Catch
Most inventors don’t rely on just one patent. Smart inventors create patent portfolios. These include multiple patents that cover different aspects of the same invention.
For example, the main patent might expire, but related “child” patents (with broader or different claims) could still be active. This means the invention isn’t completely free to use yet.
What Should You Do?
If you’re planning to make or sell something based on an expired patent, be cautious. There could be active patents tied to the original invention. A freedom-to-operate opinion can help. This is a legal review to ensure your product won’t infringe on any existing patents. It’s worth the time and effort to avoid costly lawsuits or penalties.
