¶ 18.07.01 Same or Corresponding Technical Feature Lacking Among Groups
[1] lack unity of invention because the groups do not share the same or corresponding technical feature.
Examiner Note:
1. This form paragraph may be used, for example, where the claims of Group I are directed to A + B, whereas the claims of Group II are directed to C + D, and thus the groups do not share a technical feature.
2. In bracket 1: For international applications in the international phase, identify the groups involved by Roman numerals (e.g., "Groups I and II") in accordance with the groups listed using form paragraphs 18.06 - 18.06.02. For U.S. national stage applications under 35 U.S.C. 371 , identify the groups involved by Roman numerals (e.g., "Groups I and II") where inventions have been grouped using form paragraphs 18.06 - 18.06.02, or identify the species involved where species have been listed using form paragraph 18.20.
