Patents

Before any product launch, fundraising, or Mu0026amp;A transaction, we assess your freedom to operate and draft patents designed to withstand judicial scrutiny. Our recommendations anticipates technical developments, incorporates unitary patent strategies and opt-out options, and identifies third-party patents that could block your activities. Drawing on extensive litigation experience and secondments within companies, we turn each filing into a negotiation tool. A well-structured patent becomes an asset as reliable as a property title.

Assignments, exclusive or cross-licenses, co-ownership, co-development agreements, and pledges: we negotiate and formalize the contracts that finance growth and strengthen innovation portfolios. In Mu0026amp;A transactions, we audit target patents, structure warranties, and manage rights transfers across multiple jurisdictions. Our teams balance legal control and economic performance while anticipating execution risks. Every agreement reflects a long-term strategic vision.

We advise and represent originator pharmaceutical companies, generic manufacturers and biosimilar producers in patent validity and infringement disputes covering active molecules, formulations and second medical use patents. Our practice sits at the intersection of patent law, pharmaceutical regulation and related proceedings, including supplementary protection certificates (SPCs), infringement seizure orders obtained from the ANSM, and challenges to marketing authorisations. By coordinating these strategies, we help protect therapeutic innovation while preserving market competitiveness.

We design and secure employee invention policies, including supplemental compensation programs, settlement agreements, and proceedings before the French National Commission for Employee Inventions or the courts. Working with our Labor u0026amp; Employment Law team, we tailor strategies to economic and human stakes and select the most effective procedural routes. Managing employee inventions contributes to talent retention and innovation governance, embedding intellectual property into corporate culture.

In cases involving corporate or executive liability, product liability, or professional negligence, we defend your interests in collaboration with our Litigation team and a network of technical and financial experts. We analyze insurance policies and anticipate risks linked to products, technologies, and cross-liabilities in sectors such as pharmaceuticals, automotive, telecommunications, technology, and consumer goods. Our dual legal and scientific expertise enables a comprehensive understanding of industrial risk.

Oppositions, appeals, limitations, third-party observations: we defend and challenge patents before the European Patent Office and the French Patent Office (INPI), handling both technical and procedural aspects. Our patent attorneys, who appear before these offices on a daily basis, design strategies that anticipate national effects and subsequent litigation. By mobilizing witnesses and technical experts, we build robust cases that withstand adversarial scrutiny. This continuity between filing, opposition, and enforcement creates a lasting competitive advantage.

In infringement and invalidity actions, we develop integrated litigation strategies before national courts and the Unified Patent Court. We assess the balance between defense, counterattack, and settlement, activate emergency measures, and leverage related areas of commercial and administrative law. Our pan-European approach ensures consistency in legal positions and control over judicial timelines. Each action is designed to safeguard the company’s business momentum and operational continuity.

We share our expertise through training programs delivered to clients, professional organizations, trade associations, and universities (CEIPI, EFB, IEEPI, Politecnico di Milano, CentraleSupélec, ENSTA, Ponts ParisTech). Tailored to each audience, including legal teams, engineers, works councils, sales forces, and students, our training covers key topics such as industrial property strategy, patent litigation, infringement seizures, and contract negotiation. Since 2018, we have hosted our “Patent Workshops,” a forum where practitioners exchange insights and best practices.
