An objection of lack of unity shouldmust consist of logically presented, technical reasoning containing the basic considerations behind the finding of lack of unity. WhenIf necessary, this comprises theit must comprise considerations relating to the number and grouping of the claimed separate inventions.
The objection must identify the common matter, if any, between the different (groups of) inventions and provide reasons why the common matter cannot constitute a single general inventive concept based on the same or corresponding technical features. In particular, the reasons should highlight the technical problem(s) addressed by the different inventions, unless it is perfectly clear from the remainder of the argumentation that the different inventions could not possibly be subsumed under an overall problem. For each invention or group of inventions the reasons should also specify the special technical features makingthat make a contribution over the art or the common general inventive concept, as appropriate. The objection must also include the reasons why the examiner considers that there is no technical relationship among those inventions involving one or more of the same or corresponding special technical features. In particular, the reasons must highlight the technical problem(s) addressed by the different (groups of) inventions. When the objection is based on a document, the relevant passages are appropriately identified.
