Office Action

§112
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 . DETAILED ACTION Response to Amendment Applicant's amendments filed on 06/04/2026 have been entered. Claims 1-13 are currently under examination on the merits. Any rejections and/or objections made in the previous Office action and not repeated below are hereby withdrawn. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 1-13 are 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 pre-AIA the applicant regards as the invention. Claim 1 is rejected as being vague and indefinite when these claims recite "the C9 composition comprises 20-30% monoolefins and 8-15% dienes”, because base for the percentage of monoolefins and dienes is not clear. The percentage could be based on weight, volume or mole of the total C9 composition or one of the components in the composition, it is not clear which one is the base for “20-30% monoolefins and 8-15% dienes”. Claim 2-13 are also rejected for depending from claim 1, thus inclusion of its indefinite technical features. Allowable Subject Matter Claims 1-13 would be allowable if rewritten to overcome 112 rejections as set forth above. The reason for the allowance is that the prior art of record does not specifically disclose, teach or fairly suggest an adhesive as recited in the present claim 1, wherein the copolymer A comprises repeating units derived from C8 composition, C9 composition, or coal tar light composition as claimed. The Applicant is also invited to amend the non-elected claims in order to be re-joined and further considered after elected claims being found allowable. Response to Arguments Applicant's arguments filed on 06/04/2026 have been fully considered but they are moot in view of the new grounds of rejection in light of Applicant's amendment. Conclusion THIS ACTION IS MADE FINAL. 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.
