According to Belgian patent law, the right to a patent for an invention belongs to the inventor or to its successor in title. Therefore, the right to a patent always originates from the inventor, i.e. a natural person. However, this right can be assigned to another entity, such as a company, by means of an agreement. The assignment is important because, in its absence, the inventor can request the Court to transfer the patent to itself or to be registered as co-owner of the patent if the inventor only partially contributed to the invention. Alternatively, the inventor can also request the Court to nullify the patent in its entirety, or partially, when the inventor only contributed to part of the invention.
