Caroline de Mareüil-Villette has a renowned expertise in strategy and valuation of the assets of Intellectual Property. She assists a wide range of clients, including start-ups and investors, in audits of Intellectual Property and in “due diligence” regarding rising funds.

As a European patent attorney, she is a privileged representative at the EPO in particular for opposition proceedings. She drafts legal opinions on infringement, patent validity, and freedom-to-operate studies. Her freedom-to-operate studies lead to recommendations for a strong patent strategy in order to limit or avoid counterfeiting risks on third-party patent products.

In addition, Caroline de Mareüil-Villette trains CEOs and R&D directors and managers to raise awareness of IP issues and good practices in order to prevent actions likely to penalize the protection of an invention.

Caroline de Mareüil-Villette built her career at CNRS Innovation, the IP valorization subsidiary of the Centre National de la Recherche Scientifique (National Center for Scientific Research). Then, she joined a Monaco-based firm specializing into cosmetic active ingredients where she created the Patent & Contract Department.
After living three years in Princeton, NJ (USA), she worked for a middle-sized Paris-based IP law firm. She then joined one of the major French IP law firm in 2004 where she created a department dedicated to Financial Valuation of Patents, Software & Trademarks.
