So you’ve invented a new product or process, and you’re ready to patent it. Congratulations! However, what happens if someone else files for a patent on the same invention? Or worse, what if they already have a patent on it? In this blog post, we will discuss the patent invalidation process and how to go about invalidating an existing patent. We’ll also talk about some of the common reasons patents are invalidated. If you’re worried about someone infringing on your patent, read on!
What is patent invalidation and why would someone want to do it?
Patent invalidation is the process of proving that a patent is no longer in force. This can be done for a number of reasons, including if the patent holder is not using the invention as claimed, or if the invention was already in use before the patent was filed. Invalidating a patent can be a long and expensive process, but it can be worth it for inventors who want to make sure their ideas are not being monopolized.
How to file a patent invalidation request?
There are a few different ways to invalidate a patent, but the most common is through what’s called an “interference proceeding.” This is where two or more parties claim that they have the right to make, use, or sell the same invention. The Patent Office will then decide who has the better claim to the invention, and if they find that the patent is invalid, it will be removed from the books.
Another way to invalidate a patent is through a “reexamination.” This is where someone challenges the validity of a patent by showing that there was prior art that the patent should have been aware of but wasn’t. If the Patent Office agrees, they can invalidate the patent.
Finally, a patent can also be invalidated through a “derivation proceeding.” This is where someone claims that they invented the invention before the person who holds the patent did. If the Patent Office agrees, they can invalidate the patent.

What are the possible outcomes of a patent invalidation request?
The possible outcomes of a patent invalidation request are:
(i) the patent is found to be invalid and is therefore unenforceable; or
(ii) the patent is found to be valid and enforceable. If the patent is found to be invalid, the inventor will no longer have exclusive rights to make, use, sell, or import the invention covered by the patent.
If the patent is found to be valid and enforceable, the inventor will retain those exclusive rights.
How much does it cost to invalidate a patent?
The average cost of invalidating a patent is $30,000. However, the cost can range from $15,000 to $50,000. The cost may be less if the patent is found to be invalid by the USPTO during an examination.
How long does it take to invalidate a patent?
The average time it takes to invalidate a patent is 18 months. However, the process can take up to 36 months.
Tips for successful patent invalidation
The first step in invalidating a patent is to file a petition with the USPTO. The petition must include evidence that the patent is invalid.
There are several grounds on which a patent can be invalidated, including:
- lack of novelty
- lack of utility
If the USPTO decides that the patent is invalid, it will issue a notice of invalidity. The patent owner can then appeal the decision.
Invalidating a patent can be a complex and costly process, but it is often worth it for inventors who want to protect their rights. With careful planning and execution, it is possible to invalidate a patent and stop others from infringing on your invention.
