A patent validity search is performed to examine whether a subject patent is novel or non-obvious to a person skilled in the art.​

Why is a patent invalidity search required?​

The invalidity search gives protection to an entity involved in a patent infringement lawsuit (defendant), by invalidating the claims of interest of the concerned patent of a party that filed a case or lawsuit (plaintiff)​.

When the search is performed to check the validity of the claims, it is called a validity or patent invalidation search.

The steps for performing a patent validity search and an invalidity search are similar. The only difference lies in the fact that which party is interested in getting the search done.  

  • A patent invalidity search is generally requested by an alleged infringer to get away with the infringement lawsuit.   
  • On the other hand, a patent validity search is requested by a patent holder to check the validity of the claims. 

  • Defendant – When a patent holder (plaintiff) files an infringement suit against a competitor (defendant) in the court of law for unauthorized usage of his protected invention, the defendant resorts to an invalidation search to render the claims invalid. Once the grant is declared invalid, there will be no infringement suit.   
  • Patent Holder – A patent validation analysis/search may be sought by a patent holder to check the validity of the claims before suing an alleged infringer. If no satisfactory prior art is identified during the search, the claims of the subject patent are assumed to be novel, non-obvious and have an inventive step. 
  • Potential Licensor – A patent invalidation search can be performed on behalf of a potential licensor interested in licensing the invention. The interested party (licensor) would need a license from the patent holder to manufacture or sell the products disclosing the claimed invention. Thus, before investing a huge amount of money and time in the process of licensing, the potential licensor requests a validation search.  
  • Merger and Acquisition When company ‘A’ is interested in acquiring another company ‘B’ in order to take hold of the IP owned by company ‘B’, company ‘A’ generally requests a validation search on the patent portfolio to determine the strength of the patents. 

What is Inalidator+ and how does it aid in invalidation searches?

Inalidator+ is a cutting-edge AI tool empowered by ParaBERT technology, specifically designed to streamline the process of accessing prior art for in-depth patent claim analysis. By integrating intelligent patent parameters like classification, citations, and assignees with advanced Natural Language Processing models, Inalidator+ enables users to conduct comprehensive invalidation searches effortlessly. The tool’s powerful capabilities facilitate quick identification of potentially relevant prior art, enhancing the efficiency and accuracy of the invalidation process for patents. 

The prior art may be made on many elements including patents, published patent applications, and non-patent literature. Non-patent literature may include books, evidence of sale or usage, videos, technical standards, white papers, journals, physical forms, and online resources.​

What happens if there is a prior art for the claimed invention?​

It simply indicates that your invention is not unique and has already been filed.​

What is the cost of an patent validation analysis?​

Various factors are taken into consideration to decide the cost of an patent validation analysis:

  • Level of complexity of inventions ​
  • Client budget, timeline, requirements, and expectations
  • Search report format opted by the client (summary type report or detailed claim charted format)
  • Scope of the search – when along with patent and non-patent search, the team is also performing jurisdiction based search in native languages, or standard based search where various IEEE, 3GPP, and ITSE standard are also searched.

Can a patent validity analysis be conducted on an international level?

A patent validity analysis can be conducted on an international level. Since patents are granted on a country-by-country basis, an international patent invalidity search would involve searching for prior art in multiple countries. However, it is important to note that the scope of the search may be limited by the language skills and resources of the searcher. 

What is the impact of an patent invalidation search on the patent owner?

The impact of an patent invalidation search on the patent owner can be significant. If an patent invalidation search uncovers prior art that could invalidate the patent, it could lead to a challenge to the patent’s validity. This could result in the patent being invalidated or narrowed in scope, potentially limiting the patent owner’s ability to enforce their patent rights. Additionally, an invalidity search could be used by potential infringers as a defense in a patent infringement lawsuit, making it more difficult for the patent owner to enforce their rights. 

What kind of information is included in an invalidation search report?

An invalidation search report typically includes a list of prior art references that were uncovered during the search, along with an analysis of each reference and how it relates to the patent in question. The report may also include an opinion on the patent’s validity based on the prior art uncovered during the search. The search report may include various types of prior art, including patents, patent applications, journal articles, conference papers, and other publicly available information that could potentially invalidate the patent. The report may also include information on the search methodology used, the search terms employed, and any limitations or caveats associated with the search.
