Patents and rights acquisition

At GROSSET-FOURNIER & DEMACHY we protect and enhance the value of our clients’, researchers’ and entrepreneurs’ inventions. We operate throughout France, across Europe and internationally.

A well-drafted patent creates value in a competitive field. It makes it possible to manage risk relating to infringement and the prior art, thus avoiding any litigation. It develops an enterprise’s intangible assets, making it possible to attract investors or raise finance.

For our firm, the four key strands to protecting and enhancing the value of an invention are an understanding of the science, an intelligent approach, skill with language and strategic sense. We have developed a rigorous methodology in order to apply this, and throughout the process we share our thoughts with our clients, researchers and entrepreneurs.

Our professional representatives and our patent attorneys represent our clients at the European Patent Office and the French Patent Office (INPI), promoting dialogue with the examiners. In the United States, we carry on this dialogue in conjunction with our North-American colleagues.
