MPEP § fp29.102
In replying to this Refusal electing a Group for prosecution, applicant should also consider amending the application to cancel the drawing figures and remove the description corresponding to the nonelected Group(s), and to correct inventorship, as appropriate, resulting from such amendment pursuant to 37 CFR 1.48. See MPEP § 602.01(c)(1). Applicant should note that correcting inventorship after an Office action on the merits has been given or mailed in the application will require an additional fee pursuant to 37 CFR 1.48(c).
Renumbering of the drawing figures is not required. To maintain consistency with the published International Registration, it is recommended that the numbering of the drawing figures included in the elected Group not be changed even if non-elected embodiments are cancelled. Any amendment to the drawing figures should comply with 37 CFR 1.1026 and Part Four of the Administrative Instructions (in particular, see Section 405 of the Administrative Instructions with respect to numbering of reproductions).
Add this paragraph at the end of a restriction requirement in a nonprovisional international design application. If there is no patent practitioner of record, also include form paragraph 29.100 Reply Reminder.
