Office Action

§102 §112
DETAILED ACTION 1. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . 2. This Non-Final office action is in response to application 18/155,422, application filed on 01/17/2023. Claims 1-15 are currently pending in this application. Priority 3. Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Information Disclosure Statement 4. The information disclosure statement (IDS) submitted on 01/17/2023 and 09/16/2025, respectively, is/are in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. Claim Rejections - 35 USC § 112 5. The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. 6. Claim 10 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. The rejection is as follows: Claim 10 recites the limitation "wherein the recess is configured ….", on line 5. There is insufficient antecedent basis for this limitation in the claim. Correction is required. Claim Rejections - 35 USC § 102 7. 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. 8. Claim(s) 1-15 is/are rejected under 35 U.S.C. 102(a)(1) and 102(a)(2) as being anticipated by McClelland (US PG Pub No. 2015/0318638). 9.
