At Casalonga, the patents group is split into two distinct teams: a patent prosecution and counselling team, which is led by litigators Olivier Delprat and Jean-Baptiste Lecoeur and EU patent attorneys Virginie Martin-Charbonneau and Francis Zapalowicz, and a litigation team, which is led by the triumvirate of Arnaud Casalonga, Caroline Casalonga, and Marianne Gabriel. Both teams are well versed in advising clients from the electronics, chemical, cosmetics, pharmaceutical, life sciences and mechanics sectors on a range of patent matters, and have a strong track record in working in tandem with Spanish and German colleagues to provide support on, among other areas, FRAND matters, French and European patent applications, SPC issues, and validity and infringement cases.
