How To Determine The True Inventor


Which employer, licensing, IP or R&D department of a

company has never been faced with the difficult task of

designating the inventors when filing a patent


An invention to be exploited is generally the fruit of a

collaboration chain in which each participant has made his/her

own contribution to the final work.

Distinguishing between them comes down to separating the

different participants in this value chain, and is directly

related to human resource management in the corporation.

is the fruit of the reflexion of one or several individuals. It

is therefore a question of facts in respect of the role of each

individual in the conception of the invention, and of his/her

intellectual and technical contribution.

This question of facts cannot be pre-defined by law or


Thus, in France, there is no legal definition of an


Nevertheless, an inventor designated as such in a patent

application is legally presumed to be the true inventor. The

burden of the proof to reverse such a presumption is

particularly heavy, and will be even more difficult when the

presumed inventor has also been designated as such in other

patent applications such as, for example, in the United


It is therefore essential have a "canvas"

available from the start, which will allow decision makers to

distinguish inventors from other participants in developing and
