As a general rule, an invention in the workplace by a worker who has been hired by a company to carry out an inventive activity belongs to the owner of the company unless there is an agreement to the contrary.
Only in the case in which the worker's contribution to the invention clearly exceeds their contract or working relationship will the worker have the right to supplementary remuneration.
If the worker has not been not hired to do research but creates an invention thanks to resources or knowledge acquired in the company, the business owner can decide between obtaining ownership or reserving the right to use the invention. In both cases, the worker should be financially compensated.
