Because you work in a refrigerator factory and are responsible for basic management (it should be production management, involving the production of refrigerator liners), you generally think that this is your own work or a task entrusted by a performance unit, so it is difficult for you to prove that this is a non-unit task.
Service inventions are divided into two categories:
One kind is the invention and creation completed by carrying out the tasks of the unit. Including the following three situations:
(1) Inventions and creations completed by inventors in their own work;
(2) Inventions and creations completed when performing tasks unrelated to the work delivered by the unit;
(3) Inventions and creations made within 1 year after resignation, retirement or job transfer, which are related to the job undertaken by the original unit or the tasks assigned by the unit;
The other is the invention and creation mainly using the material conditions of the unit (including funds, equipment, spare parts, raw materials or technical data that are not disclosed to the public); If only a small amount of material and technical conditions of the unit are used, and the use of such material conditions has nothing to do with the completion of the invention, it cannot be regarded as a service invention.
