Ghislain has been working for over 25 years in the fields of emerging technologies (IT, telecoms, Artificial Intelligence (AI), image processing, Internet of Things (IoT), etc.) and electronics.

His technical skills and experience enable him to understand all the issues faced by his clients, from French and foreign SMEs to multinationals, in order to support them in their industrial property policy and help them make the most appropriate decisions.

Ghislain has been a European Patent Attorney since 2005, and a French Patent Attorney since 2009. He is involved in the acquisition of IP rights, in particular in the drafting of patent applications and grant procedures, in France and in Europe, notably in the UK, and abroad, and represents his clients before the Offices.

He has also developed extensive skills defending IP rights, in opposition proceedings before patent Offices, and in managing patent, copyright (software), and unfair competition litigation, working in tandem with attorneys-at-law, in disputes before national courts. He has also acted as an expert in numerous infringement seizures.

His practice also includes the drafting and negotiation of intellectual property agreements, including licensing and assignment agreements, as well as technology transfer and consortium agreements. His knowledge of the telecom sector and his experience in the industrial world are an asset when it comes to setting up large-scale projects and managing essential patents.

He has also acquired solid expertise in intellectual property audits and analysis of software rights and licenses (especially open source).

Ghislain began his career in industry, at IBM, as an R&D engineer, where he prepared his doctoral thesis on the use of artificial neural networks in industrial environments. The author of numerous inventions, he joined the company’s French intellectual property department, where he developed his skills in patents, trademarks, copyright, and contracts.

He then spent 18 years working in a major French IP law firm, becoming a partner in 2012, before joining CASALONGA as a partner in 2024.
