What is the difference between service invention-creation, patent right and patent right? What is the right and time limit for applying for a patent?

A service invention-creation refers to an invention-creation made by an inventor or designer while performing the tasks of his own unit or mainly using the material and technical conditions of his own unit, such as an invention-creation made within one year after resigning, retiring or transferring his job, or an invention-creation made mainly using the material and technical conditions of his own unit such as funds, equipment, spare parts, raw materials or undisclosed technical data. For service inventions, the right to apply for a patent belongs to the unit. Where an invention-creation is completed by making use of the material and technical conditions of the unit and there is a contract with the inventor or designer, the ownership of the patent application right and patent right shall be determined in accordance with the contract.
