Basics Of Patent Invalidity Search

To identify patent and non-patent documents impacting a patent's validity claims, it is essential to efficiently conduct a patent invalidity search. Many entities or institutions worldwide perform patent invalidity search with a lot of speed and accuracy. Organizations conduct patent invalidity searches for validating the claims that can render a competitor's requests to become invalid. With the help of these searches, companies can check the granted patent for exploring the options of the available licenses. Patent invalidity searches are considered the preliminary steps that a company or institution takes when they face patent infringement.

We can also consider this kind of search to be a prior art search done after issuing a patent. The primary purpose of an invalid search or a patent validity search is to find the prior art that the patent examiner overlooks under different circumstances. Thus, the patent becomes invalid. When a searcher is searching for an invalid patent, it is expected that they dig deep into the domain for finding out a critical prior art that somehow passes overlooked by the patent examiner. Hence, the client can challenge any other patent that is invalid. The client can also defend a patent's allegation of infringement by another competitor, which is invalid.

Reasons Behind A Patent Validity Search Or Invalidity Search

The Patent Office might have issued the patent claims in error, which overlooks the best prior art. The patent examiners have minimal resources and time to conduct the searches from the previous art. By some accounts, the institutes allocate at an average about 12 hours per case of prosecution for the examiner's conduction of examinations of the prior art. A client may make use of the results of patent invalidity for trying to invalidate the patent by either filing the petition or litigating a patent.

The Extent Of Patent Validity Or Invalidity Search

The range of patent invalidity or validity search is usually very widely ranged, and it is extensive since an entire patent infringement lawsuit is dependent on it. Moreover, the development of new documents and shows is better than the prior art of record, and the patent examiner keeps it uncovered earlier. Thus, we can say that the search for patent invalidity is an attack on the patent, which is all-out.

The Objective Of Patent Invalidation Search

While looking into the patent invalidation search basics, we saw that this study is also known as an opposition study. This leads to certain types of arguments, such as the patent authorities, where they make the invalid patent claims. They also claim that the patent was not novel or evident at the time of filing the claim.

This process's main objective is to revoke an already registered claim for a pre-granted opposition of any published patent or application claims. Anybody would assume ordinarily that invalidations of a patent are nearly impossible projects because the authorities already grant patent that they already have scrutinized with the help of examiners of patents who are experts. When the time of advancements of databases arises and the publication of old literature on an online platform, it leads to the visibility and availability of some of the unpublished and relevant documents that become the basis of invalidation.

Recommended Practices Of Patent Invalidation Search

On a patent database platform, there are some ways of practices that the patent valuators follow and these are as follows:

- Date restriction:- A date restriction is set on the search of patents since the experts conduct the searches to locate prior art before the patents' filing date. Sometimes, we see that a patent claim has a priority, which has a priority date after the date of filing.

- Jurisdiction restriction:- There is no such jurisdiction restriction since the criteria of novelty and non-obviousness for the patent at the time of its filing is very much absolute across the world.

- Document type restriction:- Several non-formal references like that of comic strip can even destroy the authenticity of any patent and thereby render it invalid. Patent experts must consider this.

Moreover, experts must consider additional assignee-based, inventor, and citation-based searches to enhance the preparation of these searches in an optimal strategy for locating prior art. Also, for reiterating the point mentioned for patentability, experts must understand that non-patents are similarly vital as patent searches and invalidation searches.

What Are The Requirements Of A Patent Invalidity Search?

The following are requirements for conducting an invalidity search for a patent:-

- A number for the patent and the claims that the organization or patent holder needs to invalidate.

- The targeted date of priority, which is different from the date of priority listed on the patent's face.

- A prior art, which is known and not listed at the beginning of the patent.

When An Organization Usually Conducts Patent Invalidity Searches?

Under the following circumstance, patent experts or organizations who are patent holders conduct invalidity searches:-

• On receiving a patent infringement complaint from the owner of the patent.

• On receiving a desist notice from an owner of the patent.

• Before enforcing their patents for determining the risks of invalidity.

• For submissions that are pre-issued, proceedings of post-grant review and review proceedings inter partes under the America Invents Act.

To conclude, with the help of patent invalidity searches, organizations and institutions can interface during high-stakes litigation. We can have a thorough idea of the invention from this kind of search, conduct inclusive searching, supplementary searching, form interim reports, and detailed mapping to render a patent invalid. It is a powerful tool that has helped market players grab a considerable share in the landscape of technology in the emerging economies. Hence, it is inevitable that this kind of contention will lead to loss of one entity and gain for another.
