Office Action

§102
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 . Priority Acknowledgment is made of applicant’s claim for foreign priority under 35 U.S.C. 119 (a)-(d). The certified copy has been filed in parent Application No. JP2023-074514, filed on 04/28/2023. Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. 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. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claim(s) 1-10 are rejected under 35 U.S.C. 102(a)(1) based upon a public use or sale or other public availability of the invention. The instant invention is anticipated by Yabuhara et al. (US9597612B2). Regarding Claim 1, Yabuhara et al. teaches a sample preparation cartridge (See the Abstract, the solid-phase extraction containers 11, and the Claim(s) 1-15, [Col. 5 line 25]-[Col. 25 line 23] in Fig. 1-13C) comprising, in a container (See in Fig. 2A-7): a first capture unit which captures an inclusion (See the filter F2 and the solid-phase extraction material M1, i.e. a first capture unit, in [Col. 16 lines 11-28] in Fig. 4A-7 and in claim 1); a second capture unit disposed to be spaced apart from the first capture unit, which captures a contaminant (See the filter F1, i.e. a second capture unit, in [Col. 16 lines 11-28] in Fig. 4A-7); a first space provided on one surface side of the first capture unit (See the convex portion 11d, i.e. a first space, in [Col. 6 line 36]-[Col. 7 line 30] Fig. 2A-5C); a second space provided on one surface side of the second capture unit (See the combined body part 11a and the diameter-reducing part 11c, i.e. a second space, in [Col. 6 line 36]-[Col. 7 line 30] Fig. 2A-5C); a third space provided between the first capture unit and the second capture unit (See the discharge passage 11b, i.e. a third space, in [Col. 6 line 36]-[Col. 7 line 30] Fig. 2A-5C); and an inflow channel provided on an other side of the second capture unit, the second space being provided in parallel with the first space and communicated to a third space (See how the filter supplying mechanism 14a for supplies sample solution to the solid-phase extraction container 11 in [Col. 7 lines 31-56] in Fig. 1-7). Note what is discussed in MPEP § 2144 VI. concerning the rearrangement of parts of a claimed invention in comparison to the prior art. In re Japikse, 181 F.2d 1019, 86 USPQ 70 (CCPA 1950) (Claims to a hydraulic power press which read on the prior art except with regard to the position of the starting switch were held unpatentable because shifting the position of the starting switch would not have modified the operation of the device.); In re Kuhle, 526 F.2d 553, 188 USPQ 7 (CCPA 1975) (the particular placement of a contact in a conductivity measuring device was held to be an obvious matter of design choice). The current claim limitations regarding the parallel configuration of the capture units, spaces, and the inflow channel, does not change the function of the claimed invention in comparison to the prior art. Regarding Claim 2, Yabuhara et al. teaches the cartridge limitations of claim 1. Yabuhara et al. further teaches a sample preparation cartridge (See the Abstract, the solid-phase extraction containers 11, and the Claim(s) 1-15, [Col. 5 line 25]-[Col. 25 line 23] in Fig. 1-13C), wherein the first capture unit is a solid-phase extractant (See the solid-phase extraction material M1 in [Col. 16 lines 11-28] in Fig. 4A-7 and in claim 1). Regarding Claim 3, Yabuhara et al. teaches a sample preparation cartridge (See the Abstract, the solid-phase extraction containers 11, and the Claim(s) 1-15, [Col. 5 line 25]-[Col. 25 line 23] in Fig. 1-13C) comprising, in a container (See in Fig. 2A-7): a first capture unit which captures an inclusion (See the filter F2 and the solid-phase extraction material M1, i.e. a first capture unit, in [Col. 16 lines 11-28] in Fig. 4A-7 and in claim 1); a second capture unit disposed to be spaced apart from the first capture unit, which captures a contaminant (See the filter F1, i.e. a second capture unit, in [Col. 16 lines 11-28] in Fig. 4A-7); a first space provided on one surface side of the first capture unit (See the combined body part 11a and the diameter-reducing part 11c, i.e. a first space, in [Col. 6 line 36]-[Col. 7 line 30] Fig. 2A-5C); a second space provided on one surface side of the second capture unit (See the convex portion 11d, i.e. a second space, in [Col. 6 line 36]-[Col. 7 line 30] Fig. 2A-5C) ; a third space provided between the first capture unit and the second capture unit (See the discharge passage 11b, i.e. a third space, in [Col. 6 line 36]-[Col. 7 line 30] Fig. 2A-5C); and an outflow channel provided on an other side of the second capture unit, the second space being provided in parallel with the first space and communicated to the third space (See the outflow channel and holes in [Col. 7 lines 31-56] in Fig. 4D-7). Note what is discussed in MPEP § 2144 VI. concerning the rearrangement of parts of a claimed invention in comparison to the prior art. The current claim limitations regarding the parallel configuration of the capture units, spaces, and the outflow channel, does not change the function of the claimed invention in comparison to the prior art. Regarding Claim 4, Yabuhara et al. teaches the cartridge limitations of claim 3. Yabuhara et al. further teaches a sample preparation cartridge (See the Abstract, the solid-phase extraction containers 11, and the Claim(s) 1-15, [Col. 5 line 25]-[Col. 25 line 23] in Fig. 1-13C), wherein the first capture unit is a solid-phase extractant (See the solid-phase extraction material M1 in [Col. 16 lines 11-28] in Fig. 4A-7 and in claim 1). Regarding Claim 5, Yabuhara et al. teaches the cartridge limitations of claim 2. Yabuhara et al. further teaches a sample preparation cartridge (See the Abstract, the solid-phase extraction containers 11, and the Claim(s) 1-15, [Col. 5 line 25]-[Col. 25 line 23] in Fig. 1-13C), wherein a sample is passed through the solid-phase extractant, the inclusion is captured by the solid-phase extractant, and a remainder of the sample that passes through the solid-phase extractant is dispensed into an analysis unit of an automatic analyzer (See the analyzer 1 and the discharging mechanism 15 for discharging the solid-phase extraction material from the solid-phase extraction container 11 in [Col. 5 line 40]-[Col. 6 line 35] in Fig. 1).
