Office Action

§102
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 . 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. (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. Claims 1-10 are rejected under 35 U.S.C. 102(a)(1) and 35 U.S.C. 102(a)(2) as being anticipated by U.S. Patent Pub. 2020/0408604 (“Ohta”). Claim 1 Ohta discloses an electromagnetic wave detection element comprising: an electromagnetic wave detection portion (membrane 8); a conductive layer that is electrically connected to the electromagnetic wave detection portion (conductive layer 6); a conductive pillar having an end surface that is electrically connected to the conductive layer (conductive pillar 5), wherein the end surface includes an inner region that is in contact with the conductive layer (inner region 10b) and an outer region that is positioned outside the inner region (outer region 10a); and a dielectric layer that is positioned between at least a part of the outer region and the conductive layer (dielectric layer 13). Claim 2 Ohta discloses the electromagnetic wave detection element according to claim 1, wherein the inner region of the end surface has a concave portion that is recessed from at least a part of the outer region, and the conductive layer is provided along the concave portion (Fig. 10, paragraph [0088]). Claim 3 Ohta discloses the electromagnetic wave detection element according to claim 1, wherein the conductive layer has a linear portion that has a first end that is connected to the electromagnetic wave detection portion and that linearly extends from the first end, wherein as seen in a direction that is parallel to a long axis of the conductive pillar, the dielectric layer is positioned between the inner region and the first end in a path along the linear portion (Fig. 10, paragraph [0088]). Claim 4 Ohta discloses the electromagnetic wave detection element according to claim 3, wherein the dielectric layer is provided between a portion of the outer region that is positioned around an entire circumference of the outer region and the conductive layer (Fig. 10). Claim 5 Ohta discloses the electromagnetic wave detection element according to claim 3, wherein the conductive layer has a second end that is positioned opposite to the first end, and the second end is in contact with the outer region (Fig. 10). Claim 6 Ohta discloses the electromagnetic wave detection element according to claim 1, wherein in a projection image onto a projection plane that includes the outer region, the projection image being obtained by projecting the conductive layer in a direction parallel to a long axis of the conductive pillar, the conductive layer has a peripheral region that is in contact with an outer circumference of the outer region around an entire circumference of the outer region (paragraph [0059]). Claim 7 Ohta discloses the electromagnetic wave detection element according to claim 1, wherein the electromagnetic wave detection portion includes a temperature detection element and an electromagnetic wave absorbing body that covers at least a part of the temperature detection element (infrared sensor 1). Claim 8 Ohta discloses the electromagnetic wave detection element according to claim 1, further comprising a side dielectric layer that faces a side of the conductive pillar and that is integrated with the dielectric layer (Fig. 10, pillar 13 extends down with a side face). Claim 9 Ohta discloses an electromagnetic wave sensor comprising the electromagnetic wave detection element according to claim 1 (paragraph [0058]). Claim 10 Ohta discloses an electromagnetic wave sensor comprising more than one of the electromagnetic wave detection element according to claim 1, wherein the electromagnetic wave detection elements are arranged in an array (Figs. 2 and 3, arrayed).
