Office Action

§102 §112
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 . This is the first Office Action for the serial number 18/750,272, DETACHABLE AND MULTI-STRUCTURED FENCE CHAIR, filed on 6/21/24. 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 1-20 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. Claim 1, lines 2-3, “via connecting slots formed in a back side of the flip-over backrest frame body” is indefinite because the drawings in applicant’s invention show the connecting slots formed on side of the backrest frame body, not the back side of the backrest frame body. Claims 2-20 are rejected as depending on rejected claim 1. Claim Rejections - 35 USC § 102 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 (i.e., changing from AIA to pre-AIA ) 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. 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. Claim 1 is rejected under 35 U.S.C. 102(a1) as being anticipated by US Patent # 8,646,843 to Koch. Koch teaches a chair comprising a flip-over backrest frame body (30) for mounting a connecting members (70) via connecting slots (60) formed in a side of the flip-over backrest frame body and two armrest frame bodies (20) respectively connected to two sides of the flip-over backrest body via the connecting members. Allowable Subject Matter Claims 2-20 would be allowable if rewritten 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 and to include all of the limitations of the base claim and any intervening claims. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure: US Patent Application Publication # 2007/0132301 to Yu US Patent # 6,942,298 to Harrison US Patent # 8,646,843 to Koch US Patent # 5,890,767 to Chang US Patent Application Publication # 2022/0087429 to Gunawan US Patent Application Publication # 2025/0331640 to Ding et al.
