DETAILED ACTION
Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claim(s) 20 is/are rejected under 35 U.S.C. 102a1 as being anticipated by Lanew (EP 3431650 A1).
Regarding claim 20, Lanew discloses a laundry treating apparatus comprising:
a cabinet (Fig. 1, 10) defining an external surface of the laundry treating apparatus;
a drum (Fig. 1, 11) rotatably disposed in the cabinet and configured to receive laundry therein;
an air circulating channel (Fig. 2, 15) configured to receive air from the drum and resupply the air to the drum;
a heat exchanger assembly including an evaporator (Fig. 1, 17) disposed inside the air circulating channel and configured to condense moisture contained in the air (abstract), and a condenser (Fig. 1, 18) disposed at a position spaced apart from the evaporator and configured to heat the air (pg. 8, “In the Fig. 1…”);
a communication hole (Fig. 5; 36c and/or 37c) defined at one face of the air circulating channel and configured to discharge water condensed in the evaporator to an outside of the air circulating channel;
a water collector (Figs. 2/3; 21) disposed outside the air circulating channel and configured to be in fluid communication with the communication hole and to collect the water discharged from the communication hole;
a water storage tank (removable condensate collector) disposed inside the cabinet and configured to receive the water collected in the water collector (pg. 9, “By the bottom module…”) (note: the removable condensate collector is not shown in the figures but it is removable from within the dryer 1 to be emptied outside the dryer); and
a pump (Fig. 2; condensate pump in chamber 4) disposed in the water collector and configured to supply the water to the water storage tank or to the heat exchanger assembly (pg. 9, “By the bottom module…”),
wherein a bottom face of the water collector includes:
a first inclined portion (Fig. 2, 21a) inclined to decrease in height from one side of the communication hole toward the pump, and
a second inclined portion (Fig. 3, 22) inclined to decrease in height from the other side of the communication hole toward the pump,
wherein a bottom face of the air circulating channel has a third inclined portion (Fig. 5; 36d) inclined to decrease in height toward the communication hole.
Claim Rejections - 35 USC § 103
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.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
Claim(s) 21 is/are rejected under 35 U.S.C. 103 as being unpatentable over Lanew (EP 3431650 A1).
Regarding claim 21, Lanew discloses the laundry treating apparatus of claim 20, except wherein each of an inclination angle of the first inclined portion and an inclination angle of the second inclined portion are greater than an inclination angle of the third inclined portion.
However, a review of the specification shows that the limitation does not serve any advantage or particular purpose, or that it solves a particular problem. Moreover, the inclined portions in Lanew would perform equally well with the claimed inclined portions since they would all drain the condensate toward the pump.
Allowable Subject Matter
Claims 22-30 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
Claims 31-38 are allowed.
Reasons for Allowance
Lanew is the closest prior art for claim 31.
Regarding claim 31, Lanew discloses the following limitations (see rejection of claim 20 for citations) except for the bolded limitations: a laundry treating apparatus comprising: a cabinet defining an external surface of the laundry treating apparatus; a drum rotatably disposed in the cabinet and configured to receive laundry therein; an air circulating channel receive air from the drum and resupply the air to the drum; a heat exchanger assembly including an evaporator disposed inside the air circulating channel and configured to condense moisture contained in the air, and a condenser disposed at a positions spaced apart from the evaporator and configured to heat the air; a communication hole defined at one face of the air circulating channel and configured to discharge water condensed in the evaporator to an outside of the air circulating channel; a water collector disposed outside the air circulating channel and configured to be in fluid communication with the communication hole and to collect the water discharged from the communication hole; a water storage tank disposed inside the cabinet and configured to receive the water collected in the water collector; and a pump disposed in the water collector and configured to supply the water to the water storage tank or to the heat exchanger assembly, wherein a bottom face of the water collector has an inclined portion decreasing in height from an outer circumferential face of the water collector toward the pump, and wherein a bottom face of the air circulating channel has an inclined portion decreasing in height toward the communication hole.
