This is a clause to repair the loopholes in the contract. That is, in the contract law, if the contract has an agreement, it shall be governed by the agreement; if there is no agreement, it shall be governed by the statute; if the statute is not clear, it shall be governed by people's trading habits; if it is not clear, it shall be settled through arbitration or arbitration.

Regarding the repair clauses for loopholes in patent contracts, they are generally agreed upon. Patent rights that are not agreed upon belong to the research and development personnel.
Article 339 of the Contract Law:
Unless otherwise agreed by the parties, the right to apply for a patent belongs to the researcher and developer of an invention-creation developed through entrustment.
If a research developer obtains a patent right, the client can implement the patent free of charge. If a research developer transfers the right to apply for a patent, the client shall have the priority to receive the transfer under the same conditions.
