Applicant argues (pages 8-10) that in Wakaoka at 15 (the alleged bend region), the first-sheet outer face is flat and therefore the first maximum dimension at this location is zero. It follows that the first maximum dimension in the bend region is not greater than the first maximum dimension in a region other than the bend region. The Examiner respectfully disagrees; the claim language requires when viewed in a direction parallel to the bend line, the first maximum dimension in the bend region is greater than the first maximum dimension in a region other than the bend region, which is met as shown below in annotated fig 1B below. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
