Office Action

§102 §103 §112
DETAILED ACTION The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Claim Objections Claims 1-9 are objected to because of the following informalities: Each new element in the claims should be separated by a line indentation; see 37 CFR 1.75(i); Claim 3, line 3, “through a second connection piece respectively” should be --through a respective connection piece--; Similarly for claim 7. Appropriate correction is required. 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 1-9 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 recites the oblique support mechanisms comprise an oblique support rod, a bottom frame rod, a first connection pieces, and a rear support foot, however it is unclear whether the support mechanisms combined comprise these features (one of each), or each mechanism comprises these features (two of each). Claim 2 recites the limitation "both sides" in line 2. There is insufficient antecedent basis for this limitation in the claim. As seats have more than two sides, the reference to “both” is unclear. Similarly for claim 7, and the pivot of claim 6. Claim 7 recites the limitation "the seat cushion" in line 2. There is insufficient antecedent basis for this limitation in the claim. 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. Claim(s) 1 and 6-9 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Chen et al. (US 2019/0290007). Regarding independent claim 1: Chen discloses a folding swing chair comprising: a folding mechanism comprising: two uprights (21); two oblique support mechanisms, each comprising an oblique support rod (24), a bottom frame rod (242), a first connection piece (22) and a rear support foot (23 or base of rear 24); and a linkage mechanism comprising two linkage rods (1) configured to be crossed and hinged to each other (as seen in e.g. Fig 1; [0009]); wherein upper ends of the oblique rods and upper ends of the linkage rods are hinged to the respective connection pieces (Figs 1 and 3), lower ends of the linkage rods and first ends of the bottom rods are hinged to respective rear support feet (directly to 23, indirectly to rear base of 24), second ends of the bottom rods are hinged to oblique rods, and lower ends of the support rods are hinged to the linkage rods (Fig 1); wherein the oblique rods and bottom rods form a triangular structure (Fig 1) while the upright rods are tilted toward the front of the chair body (Fig 4); and the first connection pieces are slidably sleeved on the upright rods via combination through holes (Fig 2), the holes having two columnar holes with central axes intersecting (at eth very least, colinear, which intersect at all locations). Regarding claim 6: The discussion above regarding claim 1 is relied upon. Chen discloses the connection piece comprising an accommodation chamber (3), a control block (4), a spring ([0047]), and a lock pin (6), and the locking arrangement as depicted in Fig 2 and described in [0047] is generally identical to the arrangement depicted in applicant’s Fig 8. Regarding claim 7: The discussion above regarding claim 6 is relied upon. Chen discloses suspension straps (9) connected to the sides of the seat cushion (Fig 4), and the upright rods connected to and held against the straps through second connection pieces (91; [0051]). Regarding claim 8: The discussion above regarding claim 7 is relied upon. Chen discloses a third connection piece hingedly connecting the linkage rods and the upright rods (Figs 1 and 3). Regarding claim 9: The discussion above regarding claim 8 is relied upon. Chen discloses the lower ends of the oblique rods hinged to foot pads (Figs 1 and 4). 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. Claim(s) 2-5 is/are rejected under 35 U.S.C. 103 as being unpatentable over Chen et al. (‘007) in view of Frankel et al. (US 2019/0104850). Regarding claim 2: The discussion above regarding claim 1 is relied upon. Chen discloses a seat cushion supported by the upright rods (Fig 4), but does not disclose the seat supported by support rods fitting into the upright rods. Frankel teaches removable support rods (32) fitting into upright rods (31). It would have been obvious to a person having ordinary skill in the art at the time the invention was filed to have modified Chen to use removable support rods as taught by Frankel for the predictable advantage of decreasing the size, particularly the length, of the chair when in the collapsed (stowed) state for storage, and since it has been held that constructing a formerly integral structure in various elements involves only routine skill in the art. MPEP 2144.04. Regarding claims 3-5: The discussion above regarding claim 2 is relied upon. Chen discloses the structure in the same manner as above with regard to claims 7-9.
