A competitor's patent may complicate a product launch, or a business may receive an unexpected infringement warning. Understanding the available responses is essential.
A competitor's patent is not necessarily valid merely because it has been registered. A registered patent may still be invalidated if it fails to meet the relevant legal requirements.
The representative system that can be utilized at this time is the patent invalidation trial.
Today, we will look at what a patent invalidation trial is, in what cases it can be used, what the main reasons for invalidation are, and what strategic significance it has from a company's perspective.
What is a patent invalidity trial?
A patent invalidation trial is a procedure to request invalidation of an already registered patent if it does not meet the registration requirements under the Patent Act.
Simply put, “This patent should not have been registered in the first place.” It can be seen as a procedure to assert that.
If a patent is determined to be invalid, in principle, the patent rights are considered to have never existed from the beginning. Accordingly, the rights exercised by the patentee based on the patent may also be affected.
Can a registered patent be invalidated?
Many people believe that a patent that has been registered through examination by the Patent Office has been sufficiently verified for its validity.
However, it is not realistically easy to completely review all prior art and materials during the patent examination process.
As a result, if new prior art is discovered or legal issues are identified after registration, a patent invalidation trial may be filed.
In fact, in patent disputes, there are many cases where patent infringement lawsuits and patent invalidation trials proceed together. Even if the patentee claims infringement, the direction of the dispute can change significantly if grounds for invalidity exist in the patent.
In what cases can a patent invalidation trial be used?
1. When a competitor’s patent is blocking market entry
You are about to launch a new product, but your competitor may hold a patent on the related technology.
At this time, there is no need to give up business simply because a competitor's patent exists.
It is necessary to review whether the patent in question is actually a valid right.
If there are problems with patent registration requirements, barriers to market entry can be removed through a patent invalidation trial.
2. If you receive a patent infringement warning letter
Receiving a patent infringement warning is a common situation in which an invalidation trial may be considered.
If you receive a patent infringement warning or claim for damages from a competitor, it is not enough to simply review whether there is infringement.
It is also necessary to review whether grounds for invalidity exist in the other party's patent itself.
If a patent is determined to be invalid, the other party's infringement claim may also be difficult to maintain.
3. If a patent infringement lawsuit is in progress
In patent infringement lawsuits, patent invalidity trials are used as an important defense tool.
In practice, infringement lawsuits and invalidation trials are often conducted simultaneously, and in many cases, the results of invalidation trials have a significant impact on litigation strategies.
Therefore, in the process of responding to a lawsuit, it is important to review not only the infringement but also the validity of the patent.
What happens if an invalidation request is upheld?
If the invalidation decision becomes final, the patent right is, in principle, treated as never having existed.
As a result, there may be significant restrictions on the patentee's ability to exercise exclusive rights or claim infringement based on the patent.
From a company's perspective, the following effects can be expected:
- Restrictions on competitors exercising exclusive rights
- Eliminate barriers to market entry
- Reduce the risk of patent infringement disputes
- Secure negotiation power
- Expanding freedom of business activities
Therefore, it can be said that patent invalidation trials are not simply a means of attack, but an important system that is directly related to a company's business strategy.
How does the patent invalidation trial proceed?
When an invalidation request is filed, the tribunal sends a copy to the patent owner, who may submit a response within the specified period.
A hearing on the merits of the case is conducted through procedures such as arguments and rebuttals between the applicant for invalidity trial and the patentee.
- If the request for adjudication is groundless: dismissed
- If the request is well-founded: the tribunal upholds it and invalidates the patent.
The existence of a competitor's patent does not necessarily mean that it is a valid right.
If a patent infringement issue has occurred or a competitor's patent is affecting business activities, it is necessary to not only review the design-around options but also check whether grounds for invalidity exist in the patent itself.
Patent invalidation trials can be a means of checking competitors' monopolies, and at the same time, they can be a powerful defense strategy to protect companies.
Please remember that the starting point in a patent dispute is not only whether there is infringement, but also whether the patent in question is a valid right.
