Contact an attorney in patent litigation

The firm handles enquiries concerning patent litigation in France or before the Unified Patent Court, evidence measures, sending or receiving a cease-and-desist letter, a pharmaceutical launch, a SEP/FRAND negotiation or a dispute over an employee invention. It also advises companies on ownership of rights, licences, non-disclosure agreements, trade secrets and IP due diligence.

Where the strategy calls for it, the firm coordinates the work of the patent attorneys in charge of filing and EPO proceedings.

For a useful first reply

Please give the names of the parties, the court already seised if any, the date of the next deadline and, for a patent matter, the patent number. We will tell you promptly whether the firm is able to act, whether there is a conflict of interest, and on what timetable. Once that check is complete, send us all relevant documents without delay: the patent, the statement of claim, the saisie report, correspondence. In patent litigation, every day counts.

Please flag an ongoing saisie-contrefaçon or an expedited summons in your first message: your request will be handled as a priority.

We correspond in French, in English or in German. The firm acts as lead counsel or as French correspondent to a foreign law firm or patent attorney.

Conflicts of interest, confidentiality and meetings

Before any first exchange on a matter, the firm checks for conflicts of interest. The names of the parties, the patent number and the court are enough to start that check. Please do not send any confidential document until it is complete: it protects your information as much as our independence. Our exchanges are then covered by professional secrecy.

The firm is located at 7 rue Commines, in the Marais (3rd arrondissement of Paris), a short walk from Filles du Calvaire metro station (line 8). Meetings take place at the office or by video conference. Telephone: +33 1 71 60 61 46.
