Office Action

§112
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Election/Restrictions Claims 3-5 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected group, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on July 10, 2025. Claim Rejections - 35 USC § 112 Claim 2 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. In claim 2, the claimed method is indefinite in that it does not include a step wherein the protective coating is made. The single step recited is directed to preparing an ionic liquid in lieu of the preambular “protective coating” In claim 2, the phrase "melanin-type" renders the claim indefinite because the claim includes elements not actually disclosed (those encompassed by "type"), thereby rendering the scope of the claim unascertainable. See MPEP § 2173.05(d). In claim 2, line 3, given the plural “liquids”, it is unclear whether more than one ionic liquid is prepared. Response to Arguments Applicants’ arguments and amendments filed December 18, 2025 have been fully considered and are persuasive and effective to overcome the 35 USC 102 and 103 rejections over CN 112294695 A (Li) and the nonstatutory double patent rejection. Allowable Subject Matter Claim 2 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action. Claim 2 has been amended to further define the preparation of the ionic liquid. CN 112294695 A (Li) discloses a coating obtained by mixing, inter alia, poly-dopamine, aqueous nail polish and a liquid comprising 2-(2-amino-ethyl)amino ethanesulfonic acid sodium (A95). Li fails to disclose or suggest an ionic liquid prepared by polymerizing dopamine in the presence of the recited materials. An extensive prior art search has failed to reveal any additional prior art which would fairly teach, suggest or provide motivation to arrive at the presently claimed subject matter. 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.
