Invalidity Search

Invalidity Search

Even if a patent right has already been established, it does not necessarily mean that it is actually valid.

In the patent system, the success or failure depends on how a business cycle can be built with the advantage of exclusive rights.At Aztec, we assign searchers who are well versed in each field to verify the invalidity of the relevant patent from the customer's point of view.We propose results that cannot be obtained by other companies' research by conducting a multi-faceted search that digs deep into the gist and structure of the patent content.


* Invalidity Search is also called "Invalid material search", "invalidation material search", "validity search", and "publicly known case search".

\ This is an example made only by Aztec. /

Discovered a problem patent while considering a new business betting on company luck.We searched comprehensively for patents in Japan and overseas, but could not find any powerful invalid materials, so we asked our company, which is strong in searching for invalid materials.

After an in-house examination, we focused on the point of "patents related to microstructure" and conducted a search that considered not only word matching but also internal identity.As a result, we were able to find literature that proved lack of novelty and eliminate the greatest risk in business development.Although client companies are latecomers in this field, they have steadily increased their market share since then.
