J.P. Karsenty & Associés offers its clients advice and assistance at the international level.

This assistance is bolstered by the close ties it has established with well-known law firms in multiple countries all over the world, thanks notably to the law firm’s involvement in several international professional associations related to various legal fields.

  • Intellectual Property and IT Law

Intellectual property law is one of the practice areas for which the law firm is well known.

As a result of its extensive experience in trademark and patent infringement litigation and in its specific proceedings, as well as its knowledge of the specialised jurisdictions in this field, J.P. Karsenty & Associés has acquired a renowned expertise in patents, trademarks, designs, copyright and neighbouring rights.

J.P. Karsenty & Associés also applies this expertise to advise clients, in particular in the preparation of contracts (assignments, licences, coexistence agreements, know-how disclosures). The law firm also regularly represents its clients before the customs authorities.

J.P. Karsenty & Associés works with French and foreign industrial property patent and trademark agents with whom it has close ties.

J.P. Karsenty & Associés has also developed a substantial practice in IT and in Data Protection law, more particularly in drafting complex contracts in this field and in assisting its clients in litigations (before the Courts and the Data Protection Authorities) involving IT and Data Protection issues.
