CASALONGA was:

  • one of the first private IP engineer consultant firms, with the foundation of Bureau CASALONGA in Paris in 1867
  • one of the first French firms to expand internationally, with the establishment of:
    • the Munich office in 1978, as a European and German patent attorneys office
    • the Alicante office in 1996, handling of EU trademarks
      to optimize contacts with European authorities, intervene directly before the EPO (Munich) and the EUIPO (Alicante) at lower costs and to represent the clients before German and Spanish offices and courts.
  • the first French law firm to include both attorneys-at-law and patent and trademark attorneys, creating a full-service IP firm whose clients do not have to engage different firms for prosecution and litigation. The combination of attorneys-at-law and patent and trademark attorneys enables CASALONGA’s teams to follow their client’s cases from the inception phase through any court proceedings and also provides more balanced advice, taking into consideration litigations risks.

The law firm is organized in five different departments:

  • patent prosecution and counseling
  • trademark and design prosecution and counseling
  • domain names and Internet prosecution and counseling
  • wine, spirits and law food
  • IP litigation (including patent litigation and trademark and design litigation).

Those different departments work closely together, providing the clients a strength that no other firm may provide.

CASALONGA regularly exchanges with its clients in order to understand their needs and develop new IP tools to serve such needs.

In the context of the entry into force of the Unified Patent Court (UPC) and the Unitary Patent (UP), CASALONGA recently developed:

  • the UNITARY PATENT APP, accessible directly via CASALONGA's website (https://upp.casalonga.com) and available on Google Play and Apple Store, which allows one to calculate in advance the official fees required to maintain a granted patent, depending on whether the unitary patent has been chosen or not (more information here).
  • the Interactive UPC Code, freely accessible to all upon registration on www.upc-casalonga.eu, to easily navigate through all of the UPC texts and to better understand the system thanks to a number of commentaries (more information here).
