positioning

Ipsilon is an IP boutique firm of highly qualified patent and trademark attorneys, specializing in filling, prosecution, maintenance and defense of all IP rights, including patents, trademarks, designs and domain names.

We assist our clients, at all their stages of development, in the protection of their innovations, creations and trademarks:  

  • Filling and prosecution until registration.
  • Representing before the competent administrations in France, in Europe, and in the US: INPI, BOIP, EPO, EUIPO, USPTO and WIPO.
  • Maintenance (annuities, renewals) of patents, trademarks, designs and domain names.
  • Licensing-in and -out.
  • Support and advice in case of dispute, litigations, license negotiation, due diligence, coexistence or technology transfer agreements…

Unlike most IP Law Firms, we are proud to have our own teams in Europe and in the US which, together with our network of selected specialized professional partners around the world, enable us to provide an integrated service, essential to ensure the same service quality anywhere on the key markets of our clients in terms of innovation and protection.

More than service providers, we are a true partner for our clients, and combine strategic know-how, legal and technical competences and quick adaptability in client-centred missions: from managing their patents and trademarks to working out and implementing their strategies, our teams of experts around the world, are determined to provide our clients with high value-added expertise.
