 814 Indicate Exactly How Application Is To Be Restricted [R-07.2022]

 The examiner must provide a clear and detailed
 record of the restriction requirement to provide a clear demarcation between
 restricted inventions so that it can be determined whether inventions claimed in a
 divisional application are consonant with the restriction requirement and therefore subject
 to the prohibition against double patenting rejections under 35 U.S.C. 121 .
 Geneva Pharms. Inc. v. GlaxoSmithKline PLC, 349 F.3d 1373, 1381, 68
 USPQ2d 1865, 1871 (Fed. Cir. 2003). See also MPEP § 804.01 .
 

 I. SPECIES The mode of indicating how to require restriction between species is
 set forth in MPEP §
 809.02(a) .
 

 The particular limitations in the claims and the reasons why such
 limitations are considered to support restriction of the claims to a particular
 disclosed species should be mentioned if necessary to make the requirement clear. Form
 paragraph 8.01 
 or 8.02 may be
 used to require an election of species.
 

 II. INVENTIONS OTHER THAN SPECIES It is necessary to read all of the claims to determine what the claims
 cover. When doing this, the claims directed to each separate invention should be noted
 along with a statement of the invention to which they are drawn.
 

 In setting forth the restriction requirement, separate inventions
 should be identified by a grouping of the claims with a short description of the total
 extent of the invention claimed in each group, specifying the type or relationship of
 each group as by stating the group is drawn to a process, or to a subcombination, or to
 a product, etc., and should indicate the classification or separate status of each
 group, as for example, by class and subclass. See MPEP § 817 for
 additional guidance.
 

 While every claim should be accounted for, the omission to group a
 claim, or placing a claim in the wrong group will not affect the propriety of a final
 requirement where the requirement is otherwise proper and the correct disposition of the
 omitted or erroneously grouped claim is clear.
 

 III. LINKING CLAIMS The generic or other linking claims should not be associated with any
 one of the linked inventions since such claims must be examined with the elected linked
 invention. See MPEP §
 809 .
