Office Action

§DP
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 . Nonstatutory Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP §§ 706.02(l)(1) - 706.02(l)(3) for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/process/file/efs/guidance/eTD-info-I.jsp. Claims 17-1 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-7 of U.S. Patent No. 12,059,948 B2 and US 11,981,380 B2. Application 18/799,406 US 12,059,948 B2 US 11,981,380 B2 Claim 17 Claims 1, 2, 4, 5 Claim 18 Claim 6 Claim 19 Claim 7 Claim 20 Claim 1 Claim 1 Claim 21 Claim 1 Allowable Subject Matter The following is an examiner’s statement of reasons for allowance: Claims 22-26 are allowed. The prior art of record does not fairly teach or disclose, either alone or in combination: (independent claim 24) A drifting kart comprising: a baseplate comprising a chassis, a floor, a front end, and a rear end, the front end having an aperture; a frame connected to the front end of the baseplate; a drive assembly supported by the frame, the drive assembly comprising a front wheel and an electric motor configured to drive the front wheel, the front wheel positioned in the aperture; a seat connected to the rear end of the baseplate; a first rear caster wheel connected to the rear end of the baseplate; a second rear caster wheel connected to the rear end of the baseplate; a battery configured to provide electric power to the electric motor, the battery positioned forward of the seat and under the frame; and a shell attached to the frame, the battery and a portion of the drive assembly positioned inside the shell. The prior art of record does not fairly teach or disclose, either alone or in combination: (independent claim 30) A drifting kart comprising: a baseplate comprising a front end and a rear end; a frame connected to the front end of the baseplate; a drive assembly supported by the frame, the drive assembly comprising a front wheel and an electric motor configured to drive the front wheel; a shell attached to the frame; a battery configured to provide electric power to the electric motor, the battery positioned under the frame and inside the shell; a seat connected to the rear end of the baseplate; a first rear caster wheel connected to the rear end of the baseplate; a second rear caster wheel connected to the rear end of the baseplate, the second caster wheel laterally spaced apart from the first caster wheel; a rotatable member extending laterally between the first and second caster wheels, the rotatable member having an axis of rotation, the axis of rotation positioned rearward of the battery; and a hand lever connected to the rotatable member such that movement of the hand lever between a lower position and an upper position moves the first and second caster wheels, via the rotatable member, between a first position and a second position. Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.” Citation of Pertinent Prior Art The prior art made of record and cited on PTO Form 892 is considered pertinent to applicant’s disclosure. Conclusion The examiner has pointed out particular references contained in the prior art of record in the body of this action for the convenience of the applicant. Although the specified citations are representative of the teachings in the art and are applied to the specific limitations within the individual claim, other passages and figures may apply as well. Applicant should consider the entire prior art as applicable as to the limitations of the claims. It is respectfully requested from the applicant, in preparing the response, to consider fully the entire references as potentially teaching all or part of the claimed invention, as well as the context of the passage as taught by the prior art or disclosed by the examiner.
