What is a patent and why does it matter?

A patent is an intellectual property right that protects an innovation — whether a product or a process — that provides a new technical solution to a given problem and is capable of industrial application.

Any innovation can be patented, provided it meets the legal requirements of patentability, in particular novelty and inventive step over the prior art.

Securing a patent — from drafting to examination and eventual grant — requires both technical and legal expertise. It is therefore highly advisable to be assisted by a qualified Patent Attorney, who combines these skills to ensure your invention is properly protected

How does the French patent granting procedure work?

When filed as a first application to protect an invention, the timeline (in calendar months) of a French patent application examined by the INPI can be summarized as follows:

Step 1: Preparation

Before filing a patent application, careful preparation is essential. This includes identifying the technical contribution of the invention, analyzing prior art, drafting strong claims, selecting relevant drawings, and writing a clear description. These elements form the backbone of the application and determine the strength of the protection sought

Step 2: Filing

The French patent application is filed with the INPI. Your patent attorney handles the entire process on your behalf, including the monitoring of the INPI’s formal examination procedure.

Step 3: Search Report

The preliminary search report lists relevant prior art and assesses the novelty and inventive step of the invention. It is accompanied by the examiner’s written opinion. Your patent attorney reviews these documents to advise on possible responses and to assess the likelihood of the patent being granted.

Step 4: Publication

The application is automatically published 18 months after the filing (or priority) date. Publication makes the invention publicly accessible and marks the beginning of the provisional enforceability of the patent rights, pending grant.

Step 5: Grant

The patent is granted at the end of the examination phase, provided the invention meets the patentability requirements. Grant confers on the holder an exclusive right of exploitation for a maximum of 20 years.

Why work with a specialized IP firm for your patent filing?

Your time is valuable, your budget is not unlimited, and patent procedures are complex, technical, and time-consuming.

And keep in mind: filing a patent application does not guarantee that a patent will be granted. A poorly drafted patent can be easily challenged, circumvented, or even invalidated.

Each patent office (INPI, EPO, USPTO, etc.) has its own requirements.

Patent attorneys understand these national and international procedural nuances.

They help define a scope of protection that is neither too narrow nor too broad, ensuring it covers both current uses and future developments.

Protect your innovations where you do business

Have you invested in the research, development, or industrialization of a product?

To prevent competitors from overtaking you or copying your invention, it is crucial to obtain clear, strong, and enforceable protection.

A European patent allows you, with a single application, to cover up to 39 countries across Europe.

Looking to protect your invention internationally?

Security

In strict confidence, our patent attorneys review all aspects of your invention’s patentability.

They conduct prior-art and patentability searches, then recommend an approach aligned with your markets, timing, and budget — designed to secure your inventions at the best cost while maximizing their long-term economic value.

Not everything is patentable… but it can still be protected

  • Trade secrets
    Some innovations — confidential processes, manufacturing methods, algorithms — cannot or should not be patented. In such cases, trade-secret protection offers a robust alternative, provided concrete measures are implemented: restricted access, NDAs, timestamped documentation.

    Our experts can help you legally secure and leverage your know-how without exposing it.
  • Software protection
    The source code of software is covered by copyright, but this protection can be complemented by other tools: patents for innovative technical aspects, trade secrets for algorithms or training data, and database rights.

    We help you build a tailored protection strategy aligned with your business model (SaaS, API, embedded software) and your goals for value creation (licensing, fundraising, partnerships).
