Our markets: Europe, Asia and North America
Patent disputes are rarely decided in a single country. Paris and the Unified Patent Court have become strategic crossing points for European, Asian and North American right holders. Dhenne Avocats runs their cases there in line with the global strategy of each matter.

Europe: Paris and the Unified Patent Court
For a European company, the whole point is to combine national routes with the Unified Patent Court. A single UPC action can cover eighteen Member States, with a matching risk: a counterclaim for revocation can strike the patent across the same territory. The Paris Judicial Court remains a leading venue, with the saisie-contrefaçon as its instrument for gathering evidence.
The firm acts for claimants and defendants before the Paris Judicial Court and the UPC, and coordinates parallel proceedings in other countries with local counsel. For mid-sized companies, the UPC also opens direct access to a market of continental scale (SMEs and mid-caps before the UPC).
Asia: Japan, Korea, China
Japanese, Korean and Chinese companies are among the leading filers of European patents, notably in electronics, telecommunications and the life sciences. Their European disputes increasingly play out in Paris and before the UPC, whether they enforce their rights or are sued there.
The firm works with their in-house teams and usual counsel within a clear coordination framework: who does what, approval channels, budget by phase. Trade secret and licensing issues, including FRAND, which often shape these cases, are handled in the same movement (Japan and Europe: patents and trade secrets). Introductory pages are available in Japanese, Korean and Chinese.
North America: the European front of a global dispute
For US and Canadian companies and law firms, Europe is often the second front of a global dispute. The UPC offers broad territorial reach and a tight timetable, Paris an established case law and the saisie-contrefaçon. The choice of European forum bears directly on negotiations conducted across the Atlantic, especially in standard essential patent and FRAND licensing matters.
The firm handles the French and UPC side alongside lead counsel, with briefs and reporting in English.
Coordination built around the overall strategy
Every international matter starts with a scoping exercise with lead counsel or the legal department: business objectives, timetable of parallel proceedings, risks to the validity of the patent, budget. The European side then becomes a lever of the overall strategy, aligned with the other proceedings and the negotiations under way.
The firm runs a conflict check before taking on any matter.
