§103
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 . Preliminary Remarks Applicant has submitted arguments and are noted in their Remarks section. Applicant has not amended, canceled, or added any claims. Claims 19-20 were not elected and are therefore, withdrawn from examination. 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. Claims 1-5, 7-11, and 14-18 are rejected under 35 U.S.C. 103 as being unpatentable over US 2018/0223354 A1-Chang et al.

Claim 6 is rejected under 35 U.S.C. 103 as being unpatentable over US 2018/0223354 A1-Chang et al. (hereinafter Chang, has an effective filing date as of the provisional application), in view of US 8,318,479 B2-Domansky et al. (hereinafter Domansky) as applied to claim 1 above, and further in view of WO 2016/189302A1-Boutelle et al. (hereinafter Boutelle). Regarding claim 6, modified Chang teaches the invention discussed above in claim 1. Further, modified Chang teaches a test sample (DNA strand 24). However, modified Chang does not explicitly teach a test liquid is a liquid selected from a group comprising: whole blood, blood serum or plasma, urine, cerebrospinal fluid, dialysate, serous fluid, interstitial fluid, synovial fluid, intraocular fluid, lymph plasma, digestive fluid, and human tissue-containing liquid. For claim 6, Boutelle teaches an invention relating to the field of sensors and systems for measuring the amount of particular substances, for example metabolites, within a fluid sample, for example from a patient (page 1, lines 1-2) and Boutelle teaches tissue in a patient source (page 7, paragraph 11, line 6); Boutelle also teaches one body of work concentrates on monitoring glucose levels in blood (page 1, lines 10-11), which reads on the instant claim limitation of wherein the test liquid is a liquid is human tissue-containing liquid. It would have been obvious to a person having ordinary skill in the art before the effective filing date of the invention to take the modified invention of Chang discussed above in claim 1, and incorporate human tissue-containing liquid as taught by Boutelle Also, Boutelle teaches analysis apparatus allow for measuring the amount of particular substances, such as metabolites within a fluid sample, such as from a patient (page 1, lines 1-2), where the latter can be useful in monitoring physiological parameters which can provide important information (page 1, paragraph 5, lines 1-3). Response to Arguments Applicant's arguments filed 12/09/2025 have been fully considered but they are not persuasive. On the top of page 6 of applicant’s remarks, applicant discusses the status of the claims, as well as the relied upon art in the U.S.C. 103 rejection of claims 1-18 of the instant application. On the middle of page 6 of applicant’s remarks, applicant recites independent claim 1 of the instant application. Applicant’s arguments begin the bottom of page 6 and continue on the top and middle page of 7 of their remarks. On the middle of page 7 of applicant’s remarks, applicant recites a portion of the of rejection of independent claim 1 as cited in the Office Action mailed on 10/03/2025, page 4, applicant noted. On the bottom of page 7 of their remarks, applicant asserts “a person of ordinary skill in the art would have no reason whatsoever to replace Chang’s actuators with Domansky’s pneumatic valves. Further, on the bottom of page 7 and the top of page 8 of applicant’s remarks, applicant cites a portion of the disclosure of Chang. Applicant also cites another portion of the disclosure of Chang the middle and bottom of page 8 of their remarks. Applicant also cites other portions of the secondary reference, Domansky, which continues on the top and middle of page 9 of their remarks. Further, applicant continues to argue the combination of Chang and Domanksy on the bottom of page 9 and the top of page 10 of their remarks section. Applicant only cites the additional reference of Boutelle, but does not present any arguments to this reference as applicant asserts the reference does not make up for the deficiencies of Chang and Domansky. In response, it is not uncommon for microfluidic devices such as that of the claimed invention to include pneumatic actuated valves. The latter is very well known in the art and is therefore not novel. Independent claim 1 of the instant application recites “one or more moveable walls provided by the gas pressure source…”. Domanksy teaches a system has been constructed that recapitulate the features of a capillary bed through normal human tissue (col. 3, lines 24-25) and Domansky teaches the valves and pumps of all bioreactors in the array are actuated via common pneumatic control channels (col. 4, lines 22-24; col. 7, lines 62-65), also discussed in the rejection. Domanksky also teaches at least one actuator may be embedded in the substrate (para. [0003]) and Domanksy teaches the at least one actuator may be fixed to a substrate , and the nanochannel may be formed at least in part in the substrate (para. [0007]). Additionally, pertaining to applicant’s argument regarding mechanical actuator may provide Angstrom level precision control when activated (para. [0030] of Domansky is not found persuasive because it is clearly noted at the beginning of paragraph [0030], the latter pertains to a different embodiment that was also not relied upon in the present rejection nor the previously mailed rejection. Also, the combination of the references does teach pressurized air (i.e. gas) in the Domanksy reference (col. 7, lines 21-22). As discussed above in the rejection, valves and pumps of all bioreactors in the array are actuated via common pneumatic control channels, which read on the instant limitation of one or more moveable walls. Chang’s device teaches an actuator embedded in the substrate and a nanochannel formed in the substrate and Domansky teaches valves which are actuated via common pneumatic control channels, also discussed above. For the reasons discussed above, claims 1-18 stand rejected. Conclusion THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
