Patent invalidity or patent validity searches are conducted to either validate enforceability of claims of a patent or to invalidate one or more claims of some other patent (mostly of a competitor). It is the first step taken by a company facing a patent infringement lawsuit. A Patent Validity or Patent Invalidity Search is a prior art search that is conducted after issuance of a patent. These two types of searches are identical except for the desired outcome (valid or invalid patent claims) of the search. This is also sometimes referred to as an opposition search.

When should you conduct a patent validity or patent invalidation search?

When you are confronted by allegations of patent infringement, an invalidation search is the first line of defense as it serves as a proof of invalidity based on prior art. Any patent invalidation study may involve hundreds of millions of dollars at stake, therefore it requires good patent expertise and technical understanding of the person to conduct a good prior art patent invalidity search.

A Patent Validity Search may be done when a client is evaluating options of licensing, buying, or selling a patent and wants to know that the patent is enforceable. If you know whether the patent can withstand an attack on validity or not, it will help you to take an informed decision while negotiating a patent transaction deal.

Sometimes, a Patent Office may have issued patent claims in error and might possible have overlooked a prior art document. This is because patent examiners have limited time and resources to conduct their searches. A client may want to do a patent validity/invalidity search and use the search results to try to invalidate the granted patent either by litigation or by filing a petition for review of the patent at the U.S. Patent and Trademark Office or any other patent jurisdiction.
