A technological achievement is a service invention if it is completed by the unit or by using the material conditions of the unit. The patent right of service invention belongs to the unit. If a technological achievement is completed by the inventor without using the company's material conditions (such as equipment, funds, undisclosed technical information, etc.). ), the invention content has nothing to do with his own work and the scientific research tasks assigned by the company, and belongs to non-service invention. The patent right for non-service inventions belongs to individuals.
