Patents – Prior art search


Prior art search

Evaluate the patentability of your invention or the solidity of a competitor’s patent via a prior art search

In order to be patented, an invention must be novel, involve an inventive step, and have industrial applicability. These are three essential criteria for the patentability of an invention.

Before filing any patent, it is therefore necessary to check these patentability characteristics in order to ensure that an invention does not already exist (novelty) and/or that it is not obvious with regards to other inventions already known in prior art (inventive step).

Likewise, before investing in a Research and Development program (R&D), it is useful to check that your project does not risk infringing on competitors’ patents.

In the event of infringement, it is also necessary to check the validity and the scope of the patent in question.

Databases are available free of charge in order to determine the state of prior art that can affect the novelty and the inventive step of a patent (Databases from INPI, from EPO-Espacenet, from WIPO-Patentscope). But the technical and legal analysis of the documents that you find requires the skills that we offer.


➢ You wish to assess the patentability of your invention before taking the decision to file for a patent.

➢ You want to file for patents that are legally solid.

➢ You want to anticipate disputes.

➢ Before filing for a patent: we search for and analyze the state of the art that can affect the novelty and/or the inventive step of your invention.

➢ We anticipate disputes by searching for competitors’ patents that can hinder the use of a product or a method that you are considering to use, and for which you would risk being accused of infringement.

➢ In case of dispute: we search for documents that can invalidate and/or limit the scope of the competitor’s patents for which you are the infringer.
