Who owns the patent right applied for at the same time?

If the scientific research task delivered by the company is completed by different personnel belonging to different companies, it is regarded as a service invention. If there is no agreement between the two companies, the patentee belongs to both parties. If there is an agreement, the patentee shall be determined according to the agreement. If it is a non-service invention, if there is an agreement, there are two patentees without an agreement.
