Office Action

§101 §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 . In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. Status of Claims Below is the Final Action on the Merit for claims 8 – 29. Claims 1 – 7 are allowed. Double Patenting A rejection based on double patenting of the “same invention” type finds its support in the language of 35 U.S.C. 101 which states that “whoever invents or discovers any new and useful process... may obtain a patent therefor...” (Emphasis added). Thus, the term “same invention,” in this context, means an invention drawn to identical subject matter. See Miller v. Eagle Mfg. Co., 151 U.S. 186 (1894); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Ockert, 245 F.2d 467, 114 USPQ 330 (CCPA 1957). A statutory type (35 U.S.C. 101) double patenting rejection can be overcome by canceling or amending the claims that are directed to the same invention so they are no longer coextensive in scope. The filing of a terminal disclaimer cannot overcome a double patenting rejection based upon 35 U.S.C. 101. Claims 8 – 29 are rejected under 35 U.S.C. 101 as claiming the same invention as that of claims 11 – 16, 19, 21, 23, 25 – 30 of prior U.S. Patent No. 11,827,190. This is a statutory double patenting rejection. Instant Application 18/381,541 U. S. Patent No. 11,827,190 Claim 8 A snow paddle kit, comprising a snow removal paddle, a handle mountable to the snow removal paddle, and an edge cap mountable to a lower edge of the snow removal paddle, wherein: the snow removal paddle has a snow-facing surface when the edge cap is not mounted on the snow removal paddle; the snow-facing surface of the snow removal paddle has a first surface area; the snow paddle kit has a snow-facing surface when the edge cap is mounted on the snow removal paddle; the snow-facing surface of the snow paddle kit has a second surface area; and the second surface area is at least 100 square centimeters greater than the first surface area.

Response to Arguments Applicant’s arguments, see Applicants Arguments/Remarks dated November 13, 2025 with respect to the rejection of claims 1 – 7 under 35 U.S.C. 103 have been fully considered and are persuasive. Therefore, the rejection has been withdrawn. Claims 1 – 7 are allowed. Regarding the Terminal Disclaimer filed, the disclaimer does not apply to claims 8 – 29 as the rejection is a statutory type (35 U.S.C. 101) double patenting rejection and the rejection can be overcome by canceling or amending the claims that are directed to the same invention so they are no longer coextensive in scope. The filing of a terminal disclaimer cannot overcome a double patenting rejection based upon 35 U.S.C. 101. 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.
