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 § 103
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 (i.e., changing from AIA to pre-AIA ) 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.
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claims 1, 3-7 are rejected under 35 U.S.C. 103 as being unpatentable over US Patent Publication 2006/0179896 to Lim in view of KR2019/0096496 to Kwon (The art rejection is made based on the respective English translation by PE2E).
In Reference to Claim 1
Lim discloses a laundry appliance comprising: a cabinet (Fig. 3A, annotated by the examiner); a tub (Fig. 3A, 50) positioned within the cabinet, the tub defining a tub outlet and a tub inlet (As showed in Fig. 1A); a laundry basket (Fig. 3A, 20) rotatably mounted within the tub, the laundry basket defining a chamber (As showed in Fig. 3A, the chamber surrounded by basket 20) for receipt of articles for washing or drying; a motor (Fig. 1A, 44) mounted within the cabinet; and an impeller (Fig. 1A, 41) in mechanical communication with the motor to motivate rotation of the impeller about an axial direction, the impeller being rotatable along a rotational direction about the axial direction (As showed in Fig. 1A) to urge a flow of air (As showed in Fig. 3A, the flow of air marked by arrow, the Office considers that the air flow is circulated (urge) by impeller) from the chamber of the laundry basket.

Lim does not teach the detail of the impeller
Kwon teaches the impeller comprising a baseplate (Fig. 8, annotated by the examiner), and a plurality of radially accurate vanes (Fig. 8, 110) supported on the baseplate, the plurality of radially arcuate vanes each extending rearward relative to the rotational direction from an inner end (Fig. 8, annotated by the examiner) proximal to the axial direction to an outer end (Fig. 8, annotated by the examiner) distal to the axial direction; and a housing (Fig. 8, 30), the housing defining a housing cavity (Fig. 8, as showed) within which the impeller is positioned, an entrance upstream (Fig. 8, annotated by the examiner) from the impeller to permit air thereto, a cutoff (Fig. 8, 34) disposed above the impeller, and a transition duct (Fig. 8, annotated by the examiner) extending between the cutoff and an exhaust exit (Fig. 8, 32) of the housing.

Doing so, would result in the air blower design of Kwon being used in the air duct of Lim. Both inventions of Kwon and Lim having impeller type air blower to move air flow, Kwon teaches an air blower design can effectively reduce blade pass frequency and noise.
In Reference to Claims 3 and 4
The combination of Lim and Kwon as applied to Claim 1 does not teach the relative size between the blade and the cutoff.
