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 .
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 1-6 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 applications subject to pre-AIA  35 U.S.C. 112, the applicant), regards as the invention.
Regarding claim 1,
Line 16 recites the limitation the vertical direction of the drum.  There is insufficient antecedent basis for this limitation in the claim.  This can be corrected by an amendment instead reciting “a vertical direction of the drum.
Regarding claim 6,
Line 15 recites the limitation the extending direction of the driving shaft.  There is insufficient antecedent basis for this limitation in the claim.  This can be corrected by an amendment instead reciting “an extending direction of the driving shaft (as recited in claim 2).
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 § 2146 et seq. 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 filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13.
The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual 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/apply/applying-online/eterminal-disclaimer.
Claims 1-6 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-4 of U.S. Patent No. 11,898,298 (hereinafter “US’298”). Although the claims at issue are not identical, they are not patentably distinct from each other for the following reasons:
Regarding claim 1,
The claimed features of: housing, drum, driving motor, driving shaft, and driving shaft flange are anticipated by claim 1 of US’298.
Regarding claim 2,
The claimed features of the first surface, second surface, and extension portion are anticipated by claim 1 of US’298.
Regarding claim 3,
The claimed features of the first surface, second surface, and extension portion are anticipated by claim 1 of US’298.
Regarding claim 4,
The claimed features of the extension portions are anticipated by claim 4 of US’298.
Regarding claim 5,
The claimed features of the central portion and arm member are anticipated by claim 2 of US’298.
Regarding claim 6,
The claimed features of the first surface, second surface, and extension portions are anticipated by claim 3 of US’298.
Conclusion
See the attached PTO-892 for a list of the prior art made of record and not relied upon that is considered pertinent to applicant’s disclosure.


NEXT OFFICE ACTION: 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 .
Office Action is in response to Applicant’s amendments/remarks filed 1/31/25.  Claims 1 and 6 were amended.  Claims 1-6 are presently pending and are presented for examination.
Response to Arguments
Applicant’s arguments, see page 1 of remarks, filed 1/31/25, with respect to the rejections of claims 1-6 under 35 U.S.C. 112(b) have been fully considered and are persuasive.  The rejections of claims 1-6 under 35 U.S.C. 112(b) have been withdrawn.
Applicant’s arguments, see page 1 of remarks, filed 1/31/25, with respect to the rejections of claims 1-6 on the grounds of nonstatutory double patenting have been fully considered and are persuasive.  The rejections of claims 1-6 on the grounds of nonstatutory double patenting have been withdrawn.
Terminal Disclaimer
The terminal disclaimer filed on 1/31/25 disclaiming the terminal portion of any patent granted on this application which would extend beyond the expiration date of US Patent No. 11,898,298 has been reviewed and is accepted.  The terminal disclaimer has been recorded.
Allowable Subject Matter
Claims 1-6 are allowed.
The following is an examiner’s statement of reasons for allowance:
Applicant’s reply filed 1/31/25 overcomes the rejections of claims 1-6 under 35 U.S.C. 112(b) and the grounds of nonstatutory double patenting.  See the attached PTO-892 for a list of the closest prior art made of record, for example: US Pub. 2013/0327098 to Bae et al., US Pub. 2017/0356115 to Choi et al., US Pat. 7,841,800 to Gracia Bobed, US Pub. 2008/0196452 to Bae et al.  No available prior art is able to teach/disclose all features of the claimed driving shaft flange comprising first surface, second surface, and extension portion in the specifically claimed configuration and in combination with all other claim features defined by the washing machine of independent claim 1. Upon a comprehensive search no available prior art was able to teach or fairly suggest, singly or in combination, all features of the washing machine defined by independent claim 1.  For at least the above reasons, independent claim 1 (and therefore claims 2-6 depending therefrom) are in condition for allowance.
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.”
