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 § 102
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 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) 1-3, and 8 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Winkler (Pub. No. US 2017/0138489).
Regarding claim 1, Winkler discloses a spool valve (Figs. 1-12) comprising: a cylindrical sleeve (110), the sleeve (110) including two or more input ports (113) and two or more output ports (113), each communicating with inside (Figs. 1-3) of the sleeve (110); and a spool valve element (102) that slides inside (paragraph 24) the sleeve (110) in an axial direction of the sleeve (110), an open area of each of the input ports and the output ports (113) being adjusted by sliding (paragraph 25) of the spool valve element (102), wherein at least one of the sleeve (110) and the spool valve element (102) comprises, at each of both end portions (at lands 109) in the axial direction of the sleeve (110), a support portion (coating 1112 at the glands as disclosed in paragraph 49) for supporting the sliding of the spool valve element (102) by reducing a gap (1116) between an inner circumferential surface of the sleeve (110) and an outer circumferential surface of the spool valve element (102) than at other portions (paragraphs 49-50).
Regarding claim 2, Winkler discloses the spool valve (Figs. 1-12), wherein the sleeve (110) includes a first surface treated portion (paragraphs 49-50) treated with first plating (product by process) in each of both end portions of the inner circumferential surface (paragraphs 49-50) in the axial direction, and the first surface treated portion is the support portion (paragraphs 49-50).
The surface treated portion produced by plating does not limit the claim. The patentability of a product does not depend on its method of production. If the product in the product-by-process claim is the same as or obvious from a product in the prior art, the claim in unpatentable even though the prior product was made by a different process (see MPEP 2113).
Regarding claim 3, Winkler discloses the spool valve (Figs. 1-12), wherein the spool valve element (102) includes a surface treated portion (1112) treated with electrolytic plating (product by process), in each of portions (at the lands, paragraph 49) of the outer circumferential surface facing both end portions (paragraphs 49-50) of the inner circumferential surface of the sleeve (110) in the axial direction, and the surface treated portion (1112) is the support portion (paragraphs 48-50).
The surface treated portion produced by electrolytic plating does not limit the claim. The patentability of a product does not depend on its method of production. If the product in the product-by-process claim is the same as or obvious from a product in the prior art, the claim in unpatentable even though the prior product was made by a different process (see MPEP 2113).
Regarding claim 8, Winkler discloses the spool valve (Figs. 1-12), wherein the sleeve (110) includes the support portion (1112) formed with a reduced inner diameter (paragraphs 49-50), on each of both end portions of the inner circumferential surface in the axial direction (paragraphs 49-50), and a reduced amount of the inner diameter of the support portion is 4 μm or more, but 60 μm or less (paragraph 50).
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.
Claim(s) 4 and 9 is/are rejected under 35 U.S.C. 103 as being unpatentable over Winkler (Pub. No. US 2017/0138489).
Regarding claim 4, Winkler discloses the essential features of the claimed invention but lack disclosure wherein the support portion has a width of 1 mm or more in the axial direction, but 15% or less of a total length of the sleeve in the axial direction.
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to cause the support portion of Winkler to have a width of 1mm or more in the axial direction but 15% or less of a total length of the sleeve in the axial direction, since it has been held that “where the only difference between the prior art and the claims was a recitation of relative dimensions of the claimed device and a device having the claimed relative dimensions would not perform differently than the prior art device, the claimed device was not patentable distinct from the prior art device” Gardner v. TEC Syst., Inc., 725 F.2d 1338, 220 USPQ 777 (Fed. Cir. 1984), cert. denied, 469 U.S. 830, 225 SPQ 232 (1984). In the instant case, the support portion of Winkler would not operate differently with the claimed dimensions since the support portion of Winkler function in the same manner as the inventor’s disclosed support portion to reduce wear between the surfaces as disclosed in paragraph 48. MPEP § 2144.05(II)(A): Smith v. Nichols, 88 U.S. 112, 118-19 (1874) (a change in form, proportions, or degree "will not sustain a patent"); In re Williams, 36 F.2d 436, 438 (CCPA 1929) ("It is a settled principle of law that a mere carrying forward of an original patented conception involving only change of form, proportions, or degree, or the substitution of equivalents doing the same thing as the original invention, by substantially the same means, is not such an invention as will sustain a patent, even though the changes of the kind may produce better results than prior inventions.").
Regarding claim 9, Winkler discloses the essential features of the claimed invention but lack disclosure wherein the support portion has a width in the axial direction that is 2% or more, but 15% or less of a total length of the sleeve in the axial direction.
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to cause the support portion of Winkler to have a width in the axial direction that is 2% or more but 15% or less of a total length of the sleeve in the axial direction, since it has been held that “where the only difference between the prior art and the claims was a recitation of relative dimensions of the claimed device and a device having the claimed relative dimensions would not perform differently than the prior art device, the claimed device was not patentable distinct from the prior art device” Gardner v. TEC Syst., Inc., 725 F.2d 1338, 220 USPQ 777 (Fed. Cir. 1984), cert. denied, 469 U.S. 830, 225 SPQ 232 (1984). In the instant case, the support portion of Winkler would not operate differently with the claimed dimensions since the support portion of Winkler function in the same manner as the inventor’s disclosed support portion to reduce wear between the surfaces as disclosed in paragraph 48. MPEP § 2144.05(II)(A): Smith v. Nichols, 88 U.S. 112, 118-19 (1874) (a change in form, proportions, or degree "will not sustain a patent"); In re Williams, 36 F.2d 436, 438 (CCPA 1929) ("It is a settled principle of law that a mere carrying forward of an original patented conception involving only change of form, proportions, or degree, or the substitution of equivalents doing the same thing as the original invention, by substantially the same means, is not such an invention as will sustain a patent, even though the changes of the kind may produce better results than prior inventions.").
Claim(s) 5-6 is/are rejected under 35 U.S.C. 103 as being unpatentable over Winkler (Pub. No. US 2017/0138489) in view of Kihlberg (U.S. Patent No. 5,222,521).
Regarding claim 5, Winkler discloses the spool valve (Figs. 1-12), wherein the spool valve element (102) includes a second surface treated portion (1112) treated with second plating (product by process), on at least a portion of the outer circumferential surface (paragraphs 49-50) facing the first surface treated portion (1112), and a surface treated portion (1112) having a hardness higher then the adjacent mating surface (paragraph 49) but lacks disclosure wherein the second plating has a hardness higher than a hardness of the first plating.
Kihlberg teaches a spool valve (10) comprising a sleeve (12) and spool valve element (11), wherein the sleeve (12) has an inner surface having hardness (Column 2 lines 20-47), the spool valve element (11) has an exterior surface having a hardness (Column 2 lines 20-47), and wherein the exterior surface of the spool valve element (11) has a hardness higher (Column 2 lines 20-47) than a hardness of the inner surface of the sleeve (12).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the hardness of the first and second treated portions to have a hardness of the second treated portion that is harder that the first treated portion, for the advantage of preventing galling and avoiding damage due to cavitation (abstract).
Regarding claim 6, Winkler discloses the spool valve (Figs. 1-12), wherein the first plating is electroless plating (product by process), and the second plating is electrolytic plating (product by process).
The surface treated portion produced by electroless or electrolytic plating does not limit the claim. The patentability of a product does not depend on its method of production. If the product in the product-by-process claim is the same as or obvious from a product in the prior art, the claim in unpatentable even though the prior product was made by a different process (see MPEP 2113).
Claim(s) 7 and 10-12 is/are rejected under 35 U.S.C. 103 as being unpatentable over Winkler (Pub. No. US 2017/0138489) in view of ITO et al. (Pub. No. US 2022/0187027).
Regarding claims 7 and 10-12, Winkler discloses the spool valve (Figs. 1-12), the gap (1116) excluding a reduced area by the support portions (1112) is 7 μm or more, but 55 μm or less (paragraph 50), but lacks disclosure wherein in a flow rate control unit for temperature regulation, that regulates a temperature of a susceptor provided in a semiconductor manufacturing device by circulating a temperature regulation fluid to the susceptor, the spool valve regulates an output flow rate of a low-temperature fluid for reducing the temperature of the temperature regulation fluid, the low-temperature fluid being inputted in a first input port, which is one of the two or more input ports, and outputted from a first output port, which is one of the two or more output ports, and an output flow rate of a high-temperature fluid for increasing the temperature of the temperature regulation fluid, the high-temperature fluid being inputted in a second input port, which is one of the two or more input ports, and outputted from a second output port, which is one of the two or more output ports, to regulate the temperature of the temperature regulation fluid.
ITO et al. teach a spool valve (2003) for regulating an output flow rate (paragraph 132), wherein the spool valve (2003) is used in a flow rate control unit (2001) that regulates a temperature (paragraphs 131-132) of a susceptor (110).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the use of the spool valve of Winkler with a spool valve used in a flow rate control unit as taught by ITO et al. for the advantage of enabling the use of the spool valve in a heat exchange system (paragraph 123).
Claim(s) 13-14 is/are rejected under 35 U.S.C. 103 as being unpatentable over Winkler (Pub. No. US 2017/0138489) in view of Kihlberg (U.S. Patent No. 5,222,521), and further in view of ITO et al. (Pub. No. US 2022/0187027).
Regarding claims 13-14, Winkler discloses the spool valve (Figs. 1-12), the gap (1116) excluding a reduced area by the support portions (1112) is 7 μm or more, but 55 μm or less (paragraph 50), but lacks disclosure wherein in a flow rate control unit for temperature regulation, that regulates a temperature of a susceptor provided in a semiconductor manufacturing device by circulating a temperature regulation fluid to the susceptor, the spool valve regulates an output flow rate of a low-temperature fluid for reducing the temperature of the temperature regulation fluid, the low-temperature fluid being inputted in a first input port, which is one of the two or more input ports, and outputted from a first output port, which is one of the two or more output ports, and an output flow rate of a high-temperature fluid for increasing the temperature of the temperature regulation fluid, the high-temperature fluid being inputted in a second input port, which is one of the two or more input ports, and outputted from a second output port, which is one of the two or more output ports, to regulate the temperature of the temperature regulation fluid.
ITO et al. teach a spool valve (2003) for regulating an output flow rate (paragraph 132), wherein the spool valve (2003) is used in a flow rate control unit (2001) that regulates a temperature (paragraphs 131-132) of a susceptor (110).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the use of the spool valve of Winkler with a spool valve used in a flow rate control unit as taught by ITO et al. for the advantage of enabling the use of the spool valve in a heat exchange system (paragraph 123).
