I developed a patent factory. Are there any specific rules on how to divide it with me? I hope someone can give me an answer! thank you

Two or more units or individuals shall sign a written contract to jointly complete the invention and creation. This kind of contract is called cooperative development contract according to contract law. A cooperative development contract shall specify the following items: the name of the project; The content, form and requirements of the target technology; Research and development plan; Research and development funds or project investment amount and its payment and settlement methods; Ownership of equipment, equipment and materials purchased with research and development funds; Time limit, place and method of performance; Confidentiality of technical information and data and risk responsibility. In addition, it is particularly important to clarify the ownership of the right to apply for and obtain patents. Unless the contract is invalid, no matter how the agreement is agreed, it should be implemented according to the agreement. If the cooperative unit fails to reach an agreement on the right to apply for a patent for the invention and creation completed by the cooperation, then according to the provisions of this article, the right to apply for a patent belongs to "the unit or individual that has completed or * * * jointly completed".
