Fields of expertise in patent litigation
Dhenne Avocats is a French firm dedicated to patent litigation. The firm pleads before the Paris Judicial Court, the Paris Court of Appeal and the Unified Patent Court, and works on every field that attaches to a patent dispute: evidence, provisional measures, trade secrets, employee inventions, contracts and licences.
Patent litigation, in France and before the UPC
The core of the practice comes down to a few actions, often run in parallel across several territories: theinfringement action and the defence against an infringement claim, therevocation action, the provisional measures, and the building of evidence through saisie-contrefaçon or through the orders to preserve evidence before the UPC.
The choice of forum has become a strategic decision in its own right. The Unified Patent Court has opened a European route with cross-border effects, which coexists with the national courts and with opposition before the European Patent Office. That choice is weighed case by case, in the light of the timetable, the strength of the title and the exposure to a centralised revocation.
The battlegrounds that decide the same case
A patent dispute is rarely won on the title alone. The firm handles the questions that come with it, and often settle it:
- FRAND licences and standard essential patents, from the declaration made to the standards body through to the setting of the rate.
- Trade secrets, in claim and in defence, including protection of the secrets of the party searched.
- Employee Inventions, classification and additional remuneration.
- Patent contracts : licence, assignment, co-ownership, confidentiality.
- Pharmaceutical regulations and supplementary protection certificates.
- Patent valuation and assessment of damages.
- Arbitration and mediation for international licences and portfolios.
