Office Action

§112
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 . Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 06/17/2026 has been entered. Response to Amendment The Applciant’s amendment filed on 06/17/2026 has bee fully considered and made of record. As such, the rejection of claim 26 under 112(a) and (b), as outlined in the Office action mailed on 03/17/2026 have been withdrawn. Claim Rejections - 35 USC § 112 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. Claims 13, 17, 19-20 and 23-26 are 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 term “substantially” in multiple lines of claim 13 is a relative term which renders the claim indefinite. The term “substantially” is not defined by the claim, the specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably apprised of the scope of the invention. The instant specification defines a general guidelines for the phrase “substantially” on page 21 (lines 10-13). However, this definition does not provide any clarity to one of ordinary skill in the art for modification of non-numerical concept (i.e., planar mating surfaces). Allowable Subject Matter Claim 13, 17, 19-20, and 23-26 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action. Response to Arguments Applicant’s arguments, see pages 2-8, filed 05/18 and 06/17/2026, with respect to the rejection(s) of claim(s) 13, 17, 19-20 and 23-26 under Van Houten, Word, Denmead, Rodgers and Rooney have been fully considered and are persuasive. Therefore, the rejection has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made in view of 112(b) of claim 13. In addition, previously withdrawn claims 18, 21-22, 27 and 31-42 would remain withdrawn. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
