Clémence VALLÉE-THIOLLIER works with national and international customers in the field of patent law, both as regards patent acquisition procedures and consultancy on freedom-to-operate and industrial property strategy.

Further to several years of professional experience in China, she has developed a specific know-how in Chinese industrial property law, to complete her original background in European and French IP laws. Clémence VALLÉE-THIOLLIER is used to conduct training sessions about intellectual property in China or Europe, particularly for Chinese or European companies or for national offices of France (INPI, Institut National de la Propriété Industrielle) and China (SIPO, State Intellectual Property Office of China). She is also expert for the China IPR SME Helpdesk, co-funded by the European Union to provide help to European SMEs for their intellectual property rights in China.

Clémence VALLÉE-THIOLLIER is involved in a wide range of technical fields in mechanics, telecommunications and IT (automotive, medical devices, metal casting, cosmetics, food industry, waste collection, petro chemistry, computer security, signal processing, web technologies, etc.).

Beyond the drafting of patent applications and the patent procedures in Europe (including oppositions) France, China, United States, Japan, etc., Clémence VALLEE-THIOLLIER is used to conducting in-depth freedom-to-operate studies (“FTO studies”), particularly in context of due diligences. Such FTO studies are especially adapted when companies are launching new products, by investigating the existence of conflicting patents and producing summaries classifying competing patents according to their nuisance power and a risk estimation.

She provides consultancy services to companies on definition of strategies, follow-up of litigations or negotiations, setting up of internal procedures, employee awareness and training on industrial property and valuation of the patent portfolio.

Clémence VALLÉE-THIOLLIER is a member of LLR's Executive Committee.
