It doesn't matter. The ranking order of patent inventors has nothing to do with the size of their rights, and all parties are the same obligee. If there is a clear agreement on the sharing and exercise of rights, it shall be followed (the rights of all parties may be unequal, but the parties reach a consensus). Otherwise, all parties have equal rights. The ranking of inventors mainly depends on their contribution to technology and related level.
Legal objectivity:
