What is a patent?

The patent seeks to protect any invention having a technical nature. It allows its holder to have an operating monopoly on the invention and thereby, to forbid third parties from manufacturing, marketing and more generally exploiting an invention containing the claimed characteristics.

It therefore gives its holder a certain competitive advantage by giving it a technical advance on the targeted market(s) and the possibility of generating income from it (for example by granting licenses to use).

The maximum duration of protection is 20 years from the date of the registration of the patent. After this time, the patent becomes public domain information and everyone is free to use it.

Drafting, filing and defending a patent

Is the invention patentable?

To be valid, a patent must meet certain criteria defined by law, which apply cumulatively. The first criterion is novelty: this means that the patentable invention must not be described in a prior art document; the second criterion is inventive activity: the invention must not obviously result from the combination of the teachings of two prior art documents according to any person skilled in the profession. The third criterion is that of industrial application: it should be possible to manufacture or use the subject of the invention in any type of industry (including agriculture).

Strict format criteria are also required by the Intellectual Property Offices where the patent is filed, and which examine the applications and carry out their examination of form or substance. The French Office is called INPI (National Institute of Industrial Property).

Be careful though, because not everything can be patented. For instance, scientific discoveries and theories, mathematical methods, aesthetic creations, drawings, intellectual exercise methods, computer programs (software) as such, information presentations, processes of cloning, modification of the genetic identity of human beings, uses of human embryos for industrial purposes, human gene sequencing, methods of therapeutic and surgical treatments and methods of diagnosis in the medical field are not patentable subject matters.

Why call a patent attorney to draft and file a patent?

The intervention of an Intellectual Property Attorney is recommended for several reasons. Firstly, he carries out the preliminary procedures of the study and verification of prior rights (search for anteriority) and the strategic consulting with regards to the innovation project. But he also intervenes for the drafting and filing of the patent application under the application legislative requirements. Then, within the prescribed deadline, he follows up the procedures and extensions depending on the requirements and prospects of the holder of the patent application.

The domain of patents is rather complex, and the challenges related to it may be too important for a company, whatever its stage of development may be. For that reason, being helped by an experienced intellectual property attorney is extremely useful to avoid technical and legal pitfalls related to each stage of the patent lifetime: before filing a patent application, during and after the filing of the patent, during the examination phase and at the time of international extensions.

Your patents are valuable

Did you know that protecting your inventions by a patent is a way to create value for your company or your project? Beyond simply protecting technology from competition, a good management of your intellectual property rights can enable you to generate revenue and make your research and development investments profitable.

Indeed, several strategies can be considered to take advantage of your patents, including:

  • The granting of an operating license, exclusive or not,
  • Transfer of the patent
  • Contribution to the capital of your company to increase its equity and therefore its value (useful when looking for investors, etc.)

Thanks to our partnership with Brandon Valorisation, we can help you define the strategy best suited to your situation and accompany you in every step of the economic and/or financial valuation of your patents or of the owner-company.
