Office Action

§102 §103
DETAILED ACTION The nonfinal rejection sent 9/8/2025 has been withdrawn and a new nonfinal rejection has been recited below. Response to Arguments Applicant's arguments filed 11/25/2025 have been fully considered but they are not persuasive. Regarding claim 1, applicant argues on pages 8-9 of the arguments that Yamashita does no disclose the limitation “a gas releasing channel is provided in the insulating layer to discharge gas located between the accommodation groove and the conductive layer to outside” because the openings in support member 90 of fig. 4 of Yamashita are not necessarily gas opening. However, fig. 4 of Yamashita the openings in support 90 inherently performs the function of allowing gas to pass through the support member 90, so it would read on the claim language “gas releasing channel”. Applicant also argues on page 10 that Yamashita does not disclose a space between the 90 and 60 and thus does not mention any bas between 90 and 60. However, the claim language “discharge gas located between the accommodation groove and the conductive layer to outside” describes a function limitation of the “gas releasing channel”. So, since an opening in the support member 90 inherently performs the function of allowing gas to pass from one side of the support member 90 to the other, any gas that was present on the inside would be able to be discharged to the outside. Thus, claim 1 remains rejected. Claims 4 and 6 are rejected for the reasons recited below. Similarly amended claim 16 is rejected for the same reasons as in claim 1. 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 1-4, 6, 8-13, and 16 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Yamashita et al. (US 2009/0039495) (“Yamashita”).

Patentability shall not be negated by the manner in which the invention was made. Claim 5 is rejected under 35 U.S.C. 103 as being unpatentable over Yamashita et al. (US 2009/0039495) (“Yamashita”). With regard to claim 5, Yamashita does not explicitly disclose that the predetermined distance is greater than or equal to 1 um. However, fig. 4 of Yamashita discloses that the height of the support member 90 may be about 5 um. The support member 90 is also formed spaced apart from the wirings 14. See par [0084] of Yamashita. Therefore, it would have been obvious to one of ordinary skill in the art to form the distance between the terminal portion and the support member of fig. 4 of Yamashita at a distance of about 1 um in order to make sure that the terminal portion and support member do not overlap and block any connections between electrode and terminals. See par [0084] of Yamashita. Allowable Subject Matter Claim 7 is objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
