SPARLANN was created in 2013.

Inspired by the Breton word "sparlañ" meaning "protection against copying", this name reflects the firm's activity in the protection of intellectual property rights, and its close relationship with its clients. SPARLANN became a law firm in 2020, after more than 7 years as an industrial property consultant.

Since its inception, the firm has been working with companies and institutions, including at international level, to support them in developing their activities and innovations: the take-up of rights, contractualisation, the management of rights portfolios worldwide, and assistance and back-up with legal disputes.

SPARLANN now offers a wider range of services, meeting its clients’ needs with contracts involving IT and research and innovation. The firm also works in the sphere of personal data protection, e-commerce law and digital platforms.

Our values

SPARLANN develops a close relationship with its clients, with a focus on responsiveness, transparency and quality.

It decided to set up in Rennes and Brest, to draw every advantage from its roots in Brittany. This regional proximity does not prevent SPARLANN from helping companies keen to export and develop their innovations in the international market, while maintaining local links.

On an international scale

SPARLANN now collaborates with numerous correspondents throughout the world – Europe, Asia, Central and Latin America, Oceania and Africa – thanks to its active participation in various networks.

These networks enable us to provide our clients with a range of services carried out by professionals with an in-depth knowledge of foreign law. Cross-border cases are handled by our teams each day.
