Legal 500 Editorial commentary

Testimonials

Collated independently by Legal 500 research team.

  • ‘The Patents team at Casalonga is solid and efficient. During several patent disputes in the pharmaceutical field, we were able to appreciate the quality of the work and discussions with the team at Casalonga.'

  • ‘The team is very competent and available at all times.’

  • ‘High level of experience and knowledge. Very serious. Thorough work. Trustworthy.’

  • ‘Very good cooperation between CPI and lawyers, which allows them complete mastery of the case, both on the technical and legal level. This very good cooperation offers them several advantages: - the firm's lawyers acquire mastery of the technical elements (in the sense of the engineer's technique) of the case - this complementarity allows them to be comfortable with the different types of client interlocutors, whether it is the legal department, the IP department, or the engineers who are experts in the field.'

  • 'The team with which our company has always been responsive and available. The case handled was complex (technical, number of parties) and unusual. The Casalonga team defended a division into phases of the case which is unusual in France, and obtained this division.'

  • ‘We worked particularly with Marianne Gabriel and Pascaline Vincent (lawyers) and Francis Zapalowicz (CPI). They all knew how to have a very good relationship with all the people involved in this case in our company.'

  • 'I note the good contact between the lawyers and our engineer specializing in the field. The human quality of the interactions seems to me to be superior to what I have sometimes had the opportunity to see in other firms.'
