Adding a Second or Subsequent Basic Application to a Convention Patent Request

Date Published

Note: COG should be informed of any amendment to the patent request (see 5.5.4 Invention Details).

The only reason for adding an extra priority document is the possibility (as considered by the applicant) that it will materially affect the priority date of at least some of the claims.  Prior to acceptance, leave to amend can be granted and the amendment allowed without advertisement.  After acceptance leave to amend must be advertised before the amendment is allowed (reg 10.5(2)).
