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 .
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 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.
Response to Arguments
Applicant's arguments filed 06 March 2026 have been fully considered but they are not persuasive.
Applicant argues Kitada fails to explicitly disclose wherein the portion of the protective layer extending to the first surface and the second surface extends continuously without an opening on the first surface and the second surface. The examiner disagrees with applicant. Fig. 1-2 of Kitada clearly show the portion (4a) of glass layer without openings therein. Furthermore, [0060] discloses “This is because the glass layer extensions 4a ensure the protection of the ceramic body 1 near the outer edges of the baked external electrodes 3 in the formation of Ni plated external electrodes 5 and Sn plated external electrodes 6 as will be described later in this case”, and it is noted that for the glass layer 4a to provide the protection disclosed said layer would be continuous. All claims stand rejected.
Claim Rejections - 35 USC § 103
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.
Claim(s) 1, 3-11, 13-14, 16-18, & 21 is/are rejected under 35 U.S.C. 103 as being unpatentable over Cha et al. (US 2020/0066452) in view of Kitada et al. (US 2016/0090661).
