How to distinguish service inventions from non-service inventions?

(1) Engaged in the research and design of his own work; (2) Inventions and creations made by completing tasks other than their own work assigned by their own units. Because although I am not engaged in the research and design of my own job, I am assigned by the unit to participate in the research and design. In this case, the unit often expects them to realize the achievements of invention and creation, and provide them with material and technical conditions, research and design time, opportunities for further study, convenience for participating in academic discussions and technical exchanges, etc. (three) inventions made within one year after resignation, retirement or transfer of work related to their own work or the assigned tasks undertaken by the original unit. This is because invention, as information technology, has diversified carriers, including people who participate in research and design. As a carrier, human brain stores information during working life, and the information of resignation, retirement and transfer is still valid. Therefore, the completion of the research and design that was started or even nearly completed at that time should belong to the service invention. The fundamental difference between service invention and non-service invention lies in whether the resources of the unit are used for invention and creation. If it is not used, it is not a service invention, and its patent right is still obtained by myself. However, if it belongs to a service invention, its patent right is a unit, and the specific standards and relevant circumstances should be combined with the actual situation.
