However, Bracken discloses wherein the organopolysiloxane composition includes polydimethylsiloxane or poly(methyl hydrogen siloxane) (¶0066). Thus, it would have been prima facie obvious to one having ordinary skill in the art at the time the invention was made to have modify the material of the pad of Kyvik so that the organopolysiloxane composition includes polydimethylsiloxane or poly(methyl hydrogen siloxane) as taught by Bracken for the purpose of having a high coefficient of friction, tacky, gel-like elastomer that firmly secure the catheter (Bracken, ¶0009). Re Claim 20, Kyvik fails to disclose the organopolysiloxane composition has a tackiness of about 10-450 g as determined by a probe tack tester, a hardness of about 5-55 units (Shore 00), a tensile strength of about 20-800 psi, a tear strength of about 5- 200 lbs/in, and a minimum elongation of about 250-1100%. However, Bracken discloses wherein the organopolysiloxane composition has a tackiness of about 10-450 g as determined by a probe tack tester (¶0070), a hardness of about 5-55 units (Shore 00) (¶0070), a tensile strength of about 20-800 psi (¶0070), a tear strength of about 5- 200 lbs/in, and a minimum elongation of about 250-1100% (¶0070). Thus, it would have been prima facie obvious to one having ordinary skill in the art at the time the invention was made to have modify the material of the pad of Kyvik so that the organopolysiloxane composition has a tackiness of about 10-450 g as determined by a probe tack tester, a hardness of about 5-55 units (Shore 00), a tensile strength of about 20-800 psi, a tear strength of about 5- 200 lbs/in, and a minimum elongation of about 250-1100%.as taught by Bracken for the purpose of having a high coefficient of friction, tacky, gel-like elastomer that firmly secure the catheter (Bracken, ¶0009). Response to Arguments Applicant’s arguments field on 12/4/2025 with respect to claim(s) 1, 13, 17 have been considered but are not persuasive. The applicant argues with regards to the limitation“ the pad is configured to press a portion of a medical device wherein the devices is lowered onto the patient and adhered to the patient” and art Kyvik fails discloses such limitation and at least there is no pad on back of the catheter. This is found not persuasive as 26 and 14 is considered to be the pad and 26 is in the back of the catheter. Also, as claimed “press” does not means that a pressing force is applied from back. It can means that the pad can squeeze the catheter between the sides of the pad 14 and or pressed on the back as 26 can be pressed on the catheter. 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.
