Specific requirements for singularity of invention patent application

According to the provisions of the Patent Examination Guide, the specific requirements for singularity in an application for a patent for invention. The singularity of an application for a patent for invention means that an application for a patent for invention should be limited to one invention, and two or more inventions belonging to the general inventive concept can be filed as one application. Specific requirements for the singularity of an application for a patent for invention The main reasons why a patent application should meet the singularity requirements are: (1) Economic reasons: In order to prevent the applicant from obtaining the protection of several different patents for invention or utility model only by paying the cost of one patent. (2) Technical reasons: In order to facilitate the classification, retrieval and examination of patent applications. Lack of oneness does not affect the validity of the patent, so the lack of oneness should not be taken as the reason for the invalidation of the patent. Article 35 of the Detailed Rules for the Implementation of the Patent Law puts forward specific requirements for the singularity of an application for a patent for invention: two or more inventions that can be filed as a patent application and belong to a general inventive concept should be technically interrelated and contain one or more identical or corresponding specific technical features, in which the specific technical features refer to the technical features that each invention as a whole contributes to the existing technology. The above clause provides a method to judge whether two or more inventions claimed in the application belong to the general inventive concept. That is to say, two or more inventions belonging to a general inventive concept must be technically related to each other, and this relationship is indicated by the same or corresponding specific technical features in their claims. Specific technical features are concepts specially put forward to evaluate the singularity of patent applications. It should be understood as the technical features reflecting the contribution of the invention to the prior art, even if the invention has novel and creative technical features relative to the prior art, it should be determined after considering the invention of each claim as a whole. Therefore, belonging to a general inventive concept means having the same or corresponding specific technical features. Note: The above-mentioned basic concepts and principles of singularity in the application for patent for invention can also be applied to the application for patent for utility model.
