Claim/Specification Objections
4. The disclosure is objected to because of the following informalities:
Claims 1-25, The term "phase transition material layer" is unclear. Usually, a substance can undergo some phase transition, and the mode of the phase transition and the state and properties of each phase before and after the transition vary depending on the substance, and thus, it is unclear what type of material that causes the phase transition of the "phase transition material layer" recited in the claims is made of. In addition, Applicant’s pub. No. 2025/0327704, paragraph [0091] discloses “The material of phase-transition material layer 6 is desirably a material that undergoes a phase transition and changes its resistance for the electromagnetic wave (temperature) of the detection wavelength”. It is unclear that the "phase transition material layer" includes a material other than the desired configuration, and if it includes a material other than the desired configuration, it is unclear what kind of material such a phase transition material layer is made of. Therefore, the term "phase transition material layer" is unclear.
Further, the claims/specification do not specify/explain the structural/functional relations of the thermoelectric material layer and the phase transition material layer. In the other words, how can the thermoelectric material layer convert the input electrical energy into thermal energy? and how can it output? How can the input thermal energy being converted into electrical energy? and can it output? What kind of phase transition does the phase transition material layer cause?
Therefore, the invention according to the current claims/specification is unclear.
Appropriate correction is required.

Patentability shall not be negated by the manner in which the invention was made.
6. Claim(s) 1, 9-10, 12, 15, 20-21, 24-25, is/are rejected under 35 U.S.C. 103 as being unpatentable over Kabasawa et al. (Pub. No. 2016/0155927) in view of Sarwat et al. (U.S. Pub. No. 2020/0209059). Hereafter “Kabasawa” and “Sarwat”.
Regarding Claim(s) 1, Kabasawa discloses an electromagnetic wave detector (Abstract; Figure 1) comprising:
a heat-absorbing layer including a thermoelectric material layer ([0301], the detecting portion 101B may include a heat absorbing layer (not shown), and heat can be more efficiently transmitted to the thermoelectric conversion layer 123B via a heat absorbing layer);
an insulating film disposed on part of the heat-absorbing layer ([0120]; [0126], lines 4-6; [0301], the detecting portion 101B may include a heat absorbing layer (not shown), and heat absorbing layer can also function as an insulating protection film for the detecting portion 101B; Figure 6, insulating film 247, 232, 257; Figure 28, insulating film 114B);

Regarding Claim(s) 12, Kabasawa and Sarwat disclose the claimed invention except for the two-dimensional material layer is electrically connected to the heat- absorbing layer with the connecting conductor in between. Kabasawa discloses the two-dimensional material layer is electrically connected to the heat- absorbing layer with the connecting conductor in between (figure 28, the supporting portion 102B is not different from two-dimensional material layer which is electrically connected to thermoelectric layer 123B; wherein, thermoelectric layer is a portion of the heat- absorbing layer. Therefore, the two-dimensional material layer 102B is electrically connected to the heat- absorbing layer; [0301]).
