The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Status of Claims
The claim set submitted on 05 JANUARY 2026 is acknowledged and considered.
In the claim set, Claims 1, 2, 10, and 14-19 are ‘Currently Amended’; Claims 3-9 and 11-13 are either ‘Original’ or ‘Previously Presented’.
Current pending claims are Claims 1-19 and are considered on the merits below.
Information Disclosure Statement
The information disclosure statement (IDS) submitted on 24 OCTOBER 2025 was filed. The submission is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner.
Response to Amendment / Arguments
Applicant’s arguments, see REMARKS, filed 05 JANUARY 2026, with respect to objection to the specification, objection to the drawings, claim objections, and the 112(b) rejections have been fully considered and are persuasive. The objection to the specification, objection to the drawings, claim objections, and the 112(b) rejections have been withdrawn.
Applicant’s arguments with respect to claim(s) 1-19 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument.
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, 16 and 19 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.
In Claims 1, 16 and 19, in the newly added portion where it recite ‘perpendicular to the normal of hydrophilic filter’; normal of what? It is unclear what ‘the normal’ is. Furthermore, to the Examiner either a word is missing or is unclear to what ‘the normal’. The word ‘normal’ does not appear in the specification.
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.

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.
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 14 is rejected under 35 U.S.C. 103 as being unpatentable over PANASONIC, JPWO 2017154349 A1.
Regarding Claim 14: wherein the nucleic acid extraction container according to claim 4, wherein an average cross-sectional area of the third channel is smaller than an average cross-sectional area of the first channel.
It would be obvious to one having ordinary skill in the art before the effective filing date to modify the average cross-sectional area of the third channel so that it is smaller than the average cross-sectional area of the first channel to control the flow rate of fluid through the channels of the device for specific flow rate of fluid onto the filter part for control reaction/filter/extraction of analytes in the device, and dimension of the channels are a result effective variable for controlling the amount and flow rate of fluids through the device. A particular parameter must first be recognized as a result-effective variable, i.e., a variable which achieves a recognized result, before the determination of the optimum or workable ranges of said variable might be characterized as routine experimentation. In re Antonie, 559 F.2d 618, 195 USPQ 6 (CCPA 1977), also In re Boesch, 617 F.2d 272, 205 USPQ 215 (CCPA 1980).
Conclusion
