Office Action

§103 §DP
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 . Response to Amendment Claims 21 and 23-37 are pending, claims 1-20 and 22 having been cancelled, claim 35 having been withdrawn and claims 36 and 37 having been newly added. Applicant's response filed February 20, 2026 is acknowledged. Claims 21, 23-34, 36 and 37 will be examined on the merits. Election/Restrictions Newly submitted claims 36 and 37 directed to an invention that is independent or distinct from the invention originally claimed for the following reasons: Inventions I (the originally elected claims) and II (the newly added claims 36 and 37) are related as process and apparatus for its practice. The inventions are distinct if it can be shown that either: (1) the process as claimed can be practiced by another and materially different apparatus or by hand, or (2) the apparatus as claimed can be used to practice another and materially different process. (MPEP § 806.05(e)). In this case, the method as claimed can be practiced by hand. Since applicant has received an action on the merits for the originally presented invention, this invention has been constructively elected by original presentation for prosecution on the merits. Accordingly, claims 36 and 37 are withdrawn from consideration as being directed to a non-elected invention. See 37 CFR 1.142(b) and MPEP § 821.03. To preserve a right to petition, the reply to this action must distinctly and specifically point out supposed errors in the restriction requirement. Otherwise, the election shall be treated as a final election without traverse. Traversal must be timely. Failure to timely traverse the requirement will result in the loss of right to petition under 37 CFR 1.144. If claims are subsequently added, applicant must indicate which of the subsequently added claims are readable upon the elected invention. Should applicant traverse on the ground that the inventions are not patentably distinct, applicant should submit evidence or identify such evidence now of record showing the inventions to be obvious variants or clearly admit on the record that this is the case. In either instance, if the examiner finds one of the inventions unpatentable over the prior art, the evidence or admission may be used in a rejection under 35 U.S.C. 103 or pre-AIA 35 U.S.C. 103(a) of the other invention. Double Patenting Claims 21 and 23-34 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-10 of U.S. Patent No. 11,963,647 to Lee et al. Although the claims at issue are not identical, they are not patentably distinct from each other because of the following: The rejection of claims 21 and 23-34 on the ground of nonstatutory double patenting is provided in the previous Office Action, which are maintained for the recitations previously identified. It is noted that the ‘647 patent further discloses the newly added claim limitations “corresponding to different time points in an event timeline” and “based on the information on two or more pollution maps among the plurality of pollution maps related to a time point in the event timeline when a predetermined event occurs (see the ‘647 patent claim 1). Furthermore, it is noted that the claims in the present application are broader than the claims of the ‘647 patent. In general, a claim that simply omits features of another claim will be considered obvious over that other claim. 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.
