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 . Election/Restrictions Claims 17-18 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected Group II, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on 12/8/25. 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. Claims 1-16 and 19-22 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Esquivel-Upshaw et al. (US 2021/0003528 and fully incorporated US 2020/0333286).

Regarding claim 8, the biosensor cartridge of claim 6, wherein the upper housing and the lower housing are fused and integrated and accommodate the sensor chip and the circuit board (fused is a process that is not given any structure weight in claims directed to a device. The prior art provides an adhesive layer 1512 between upper housing 1515 and lower housing 1509). Regarding claim 9, the biosensor cartridge of claim 1, wherein the circuit board further includes: a first surface (1509) on which the connection terminal is formed; and a reinforcing member (adhesive layer 1512 or structure 1515) that entirely covers a second surface of the circuit board, the second surface of the circuit board being opposite to the first surface. Regarding claim 10, the biosensor cartridge of claim 4, wherein the housing includes an upper surface, wherein the accommodating portion (sample opening of fig. 13) of the housing is recessed from the upper surface of the housing, has an inclined surface (90 degree inclined surface), has a diameter that gradually decreases away from the upper surface (See fig. 13 sample opening), and accommodates the analysis specimen for being introduced into the sensor area of the sensor chip, and wherein the biosensor cartridge further includes a sealing part (adhesive layer 1512; para 55) sealing between an end of the inclined surface and the sensor area (see fig. 13). Regarding claim 11, the biosensor cartridge of claim 10, wherein the sealing part includes a sealing opening having a larger diameter than a diameter of the end of the inclined surface (see fig. 15, channel is included in the adhesive layer which is larger diameter than the inclined surface opening for the sample as seen in fig. 15), and wherein the sealing opening is aligned with the accommodating portion and the sensor chip so that the sealing opening exposes the sensor area (see fig. 15).

Regarding claim 19, Esquivel-Upshaw discloses a biosensor cartridge comprising: a housing including: an upper surface (1515; fig. 13, 15) having an accommodating portion in the form of an inclined recessed hole (vertical recessed hole in the upper surface 1515 being at 90 degrees to the lower surface), and a lower surface (1509); a circuit board (see fig. 15, 16) including: a plurality of connection pads (area which contacts the sample and reactant), and a connection terminal (portion that connects to external diagnostic device) configured to be electrically connectable to an external diagnostic device (see fig. 4-5; the external diagnostic device is not positively stated in the instant claim); and a sensor chip (portion of cartridge that houses reactant) including a reactant (anti-sars-Cov-2 Antibody, para 53) in electrical contact with the plurality of connection pads of the circuit board (the sensor chip is in contact with the circuit board to transmit the signal/reaction to the connection terminal and then to the external diagnostic device), the sensor chip includes a reactant (anti-sars-Cov-2 Antibody, para 53) and the sensor chip being configured to: detect a target material from an analysis specimen, and transmit an electrical signal to the connection terminal of the circuit board, the electrical signal being generated by a reaction of the reactant with the analysis specimen (this limitation does not further structurally limit the instant claim because the target material in a specimen is not positively recited as part of the biosensor cartridge. Esquivel-Upshaw is structurally capable of performing the above function due to the same structures being recited in claim 19). Regarding claim 20, the biosensor cartridge of claim 19, further comprising a plurality of connecting members (the length of contacts between the circuit board and the sensor chip area having the reactant) disposed between the circuit board and the sensor chip, wherein the sensor chip includes a plurality of pads, and wherein the plurality of pads are in electrical contact with the plurality of connection pads of the circuit board via the plurality of connecting members (see fig. 8-16).

Regarding claim 22, the biosensor cartridge of claim 21, wherein each of the plurality of connecting members further includes a bending portion extending from the second surface and towards the first surface, and wherein the bending portion causes the second surface to be elastically deformable (the substrate is made of plastic is structurally capable of being bent. There is not structure that makes a bending portion in the instant claim like slats or cuts that would reduce mechanical stiffness).
