Abstract: The reasonable sharing of innovation benefits for service inventors is an effective incentive to achieve innovation and implementation of service inventions. The Amendment of Patent Law (Draft) had clarified this incentive method. As the value manifestation of the intellectual achievements and the institutional incentive to promote the transformation of inventions, it is legitimate to share the innovation benefits with the service inventors reasonably. However, the limited "contractual priority", the vague standard of the "reasonable" principle, the restrictive provisions of regulations on state-owned assets, the miscellaneous treatment of the rights related to service inventions, and inadequacy intellectual property operation capabilities of the unit's hinder the realization of the innovation benefits for service inventors. To realize the reasonable sharing of innovation benefits by service inventors, the criterion of "rationality" should be clarified firstly, that is, the reasonable sharing should be confirmed according to the degree of creative contribution of service inventors and the economic benefits generated by service inventions on the basis of procedural justice. Secondly, as a "bundle of rights", the patent right of service invention should be divided into different parts so as to clarify the right relationship. Thirdly, it is necessary to optimize the management system of state-owned service invention, that is, to establish a management system which takes the technology legal system as the core and is compatible with regulations of other domains. Fourth, it is more sensible to encourage the sharing of profits between the unit and the service inventor by agreement. Finally, to realize the mutual benefit between the entity and the service inventor and the transformation and utilization of service invention, it is necessary for the entity to improve the operation capacity of intellectual property.
