Blurton further discloses wherein each of said first (D) and second flex regions (F) is configured to bend and thereby allow said first (530) and second resilient, flexible members (520) to follow the contours of said respective first (14) and second buttocks (15) (annotated figure 4/figure 20, the first [D] and second flex regions [F] each comprises a compression element [330/340] that are flexible to bow or bend in response to force applied to the first [530] and second resilient, flexible members [520]; this allows the first [530] and second resilient, flexible members [520] to follow the contours of the respective first [14] and second buttocks [15]: paragraph 0050). Allowable Subject Matter Claims 1-3 and 6-16 are allowed. The following is a statement of reasons for the indication of allowable subject. Claim 1 contains allowable subject matter because the prior art fails to disclose, either singly or in combination, the limitations of the claim. The closest prior art made of record was Blurton et al. (US 20070260163 A1). Blurton et al. discloses a perianal support device (500 – figure 18, a support system to provide perianal support: paragraph 0049) for use on a patient (the patient support device [500] is to provide perianal support to a human patient: paragraph 0049), comprising: a central support element (410 – figure 18, a compliant pad to form a contact surface: paragraph 0047/0049) comprising a compression surface apex (A – see annotated figure 3, a compression surface apex) configured to extend across an anal orifice of the patient (38 – figure 19, anal orifice of a patient: paragraph 0051) in a sagittal plane of the patient (figure 19, the central support element [410] comprising the compression surface apex [A] is dimensioned to span across the anal orifice [38] when the perianal support device [500] is advanced toward the anal orifice [within the sagittal plane]: paragraph 0052); a first compression element comprising a first resilient, flexible member (530 – figure 19/figure 20, an elongated fixation member: paragraph 0049/0052) configured to follow a first contour of a first buttock of the patient (14 – figure 19, first buttock of the patient: paragraph 0051) and a first surface (532 – figure 18, a first surface containing the first half of a releasable fastening system, such as hook and loop: paragraph 0049) configured to face the first buttock of the patient (14) (figure 18/figure 19, the first surface [532] faces the first buttock of the patient [14]), the first surface (532) having a first lateral extent (B – see annotated figure 4, a first lateral extent) configured to releasably attach to a first anchor pad (534 – figure 18/figure 19, an anchor pad that is rectangular in shape: paragraph 0049) placed on the first buttock (14) (figure 18/figure 19, the anchor pad [534] is adhered to the first buttock [14]; the first surface [532] having the first lateral extent [B] is releasably attached to the first anchor pad [534] via hook and loop system: paragraph 0049/0052); a second compression element comprising a second resilient, flexible member (520 – figure 19/figure 20, an elongated fixation member: paragraph 0049/0052) configured to follow a second contour of a second buttock of the patient (15 – figure 19, second buttock of the patient: paragraph 0051) and a second surface (522 – figure 18, a second surface containing the first half of a releasable fastening system, such as hook and loop: paragraph 0049) configured to face the second buttock of the patient (15) (figure 18/figure 19, the second surface [522] faces the second buttock of the patient [15]), the second surface (522) having a second lateral extent (C – see annotated figure 4, a second lateral extent) configured to releasably attach to a second anchor pad (524 – figure 18/figure 19, an anchor pad that is rectangular in shape: paragraph 0049) placed on the second buttock (15) (figure 18/figure 19, the second anchor pad [524] is adhered to the second buttock [15]; the second surface [522] having the second lateral extent [C] is releasably attached to the second anchor pad [524] via hook and loop system: paragraph 0049/0052); a first flex region (D – see annotated figure 4, a first flex region) between a proximal end of said first compression element (E – see annotated figure 4, proximal end of the first compression element) and said central support element (410) (see annotated figure 4, the first flex region [D] is between the proximal end of the first compression element [E] and the central support element [410]); and a second flex region (F – see annotated figure 4, a second flex region) between a proximal end of said second compression element (G – see annotated figure 4, proximal end of the second compression element) and said central support element (410) (see annotated figure 4, the second flex region [F] is between the proximal end of the second compression element [G] and the central support element [410]). However, none of the relevant prior art discloses wherein the first and second resilient, flexible members comprise a thin plastic substrate, and wherein the thin plastic substrate comprises a common substrate extending continuously from a first distal end of the first compression element, across the central support element, to a second distal end of the second compression element. Therefore, claim 1 is allowable. Claims 2-3 and 6-16 are allowable based on their dependence on claim 1. Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.” 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.
