Office Action

§102 §103
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 . Drawings The drawings are objected to under 37 CFR 1.83(a). The drawings must show every feature of the invention specified in the claims. Therefore, the “second elastic element” in claims 9 and 19 and the “third elastic element” in claims 10 and 20 must be shown or the feature(s) canceled from the claim(s). No new matter should be entered. Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance.

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. Claims 2-3, 8, 12-14 and 18 are rejected under 35 U.S.C. 103 as being unpatentable over Pang. Re. Cl. 2, Pang discloses: the second assembly comprises an insertion portion 17 and top cover shown in Fig. 3, Figs. 5) and a first clamping portion (16, Fig. 5) fixedly connected with the insertion portion (see Fig. 5); and wherein the first clamping portion is of a plate-shaped configuration (see Fig. 5), and a plate surface of the first clamping portion is perpendicular to the mating direction (see Fig. 2-6). Re. Cl. 3, Pang discloses: the first assembly comprises a receiving portion (13, Fig. 4) and a second clamping portion (25, Fig. 4) connected with the receiving portion; the receiving portion comprises a first through hole and a side wall surrounding the first through hole (see Fig. 4, open end of 13 where 17 enters); the insertion portion is configured to be inserted into the first through hole from one end of the receiving portion (see Fig. 2-6), so that the first assembly and the second assembly are mated with each other (see Fig. 2-6); the second clamping portion is of a plate-shaped configuration (see Fig. 4), and a plate surface of the second clamping portion is perpendicular to the mating direction (see Fig. 2-6); the clamping space is a space located between the first clamping portion and the second clamping portion (see Fig. 2-6). Re. Cl. 8, Pang discloses: the insertion portion comprises a base portion with a rectangular section (see 17, Fig. 3-5), and a sealing plate fixedly connected to an opening side of the base portion (see top cover shown in Fig. 3). Re. Cl. 12, Pang discloses: A supporting device (Fig. 2), comprising: a first assembly (4, Fig. 3), the first assembly being configured to be connected to a supported object (see Fig. 3, via 1); a second assembly (5, Fig. 3); the first assembly being telescopically movable with respect to the second assembly along a mating direction so as to form a changeable clamping space formed between the first assembly and the second assembly (see Fig. 3-11, with or against the force of the spring 8); the clamping space being configured to clamp a target object (see Fig. 11); and a limiting mechanism (8, 18, 14, 15, Fig. 4-6) configured to make the first assembly and the second assembly in a relatively fixed state so as to securely keep the target object (see Fig. 11, the parts listed above cooperate to hold the first and second assemblies in a relatively fixed state to clamp the object therebetween). Re. Cl. 13, Pang discloses: the second assembly comprises an insertion portion 17 and top cover shown in Fig. 3, Figs. 5) and a first clamping portion (16, Fig. 5) fixedly connected with the insertion portion (see Fig. 5); and wherein the first clamping portion is of a plate-shaped configuration (see Fig. 5), and a plate surface of the first clamping portion is perpendicular to the mating direction (see Fig. 2-6). Re. Cl. 14, Pang discloses: the first assembly comprises a receiving portion (13, Fig. 4) and a second clamping portion (25, Fig. 4) connected with the receiving portion; the receiving portion comprises a first through hole and a side wall surrounding the first through hole (see Fig. 4, open end of 13 where 17 enters); the insertion portion is configured to be inserted into the first through hole from one end of the receiving portion (see Fig. 2-6), so that the first assembly and the second assembly are mated with each other (see Fig. 2-6); the second clamping portion is of a plate-shaped configuration (see Fig. 4), and a plate surface of the second clamping portion is perpendicular to the mating direction (see Fig. 2-6); the clamping space is a space located between the first clamping portion and the second clamping portion (see Fig. 2-6). Re. Cl. 18, Pang discloses: the insertion portion comprises a base portion with a rectangular section (see 17, Fig. 3-5), and a sealing plate fixedly connected to an opening side of the base portion (see top cover shown in Fig. 3). Re. Cls. 2-3, 12-14 Pang discloses that the second assembly is partially inserted into the first assembly or the opposite of what is claimed by the Applicant. In other words, Pang discloses the insertion portion is on the second assembly and the receiving portion is on the first assembly. It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention with reasonable expectation of success to reverse parts (4) and (5) of Pang, since it has been held that a mere reversal of the essential working parts of a device involves only routine skill in the art. In re Einstein, 8 USPQ 167. Please note that in the instant application, Applicant has not disclosed any criticality for the claimed limitations. Claim 11 is rejected under 35 U.S.C. 103 as being unpatentable over Tseng in view of Chou US 2023/0211473 (hereinafter Chou). Re. Cl. 11, Tseng does not disclose an auxiliary supporting piece; wherein the auxiliary supporting piece is rotatably installed on a side wall end of the receiving portion that is fixedly connected with the second clamping portion; an accommodating groove is defined on a plate surface of the second clamping portion away from the receiving portion; the auxiliary supporting piece in a non-working state is accommodated in the accommodating groove. Chou discloses a supporting device (Fig. 1) which includes opposing first and second assemblies (2, 3, Fig. 1) which function to clamp an object between opposing clamping portions (see Fig. 9). Re. Cl. 11, Chou discloses an auxiliary supporting piece (5, Fig. 4); wherein the auxiliary supporting piece is rotatably installed on a side wall end of the receiving portion that is fixedly connected with the second clamping portion (see Fig. 1, fixed to 311); an accommodating groove (see Fig. 2, groove between 311s where 5 fits) is defined on a plate surface of the second clamping portion away from the receiving portion (see Fig. 2); the auxiliary supporting piece in a non-working state is accommodated in the accommodating groove (see Fig. 3 and 9). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the Tseng device to have the auxiliary supporting piece of Chou with reasonable expectation of success since Chou states that such a modification would enable clamping of objects having different configurations (Paragraph 0026, Lines 1-5). Allowable Subject Matter Claims 6, 9-10, 17 and 19-20 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including 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. Barron US 2015/0217908, Chen US 6679463, Cunningham US 2017/0143087, and Depay US 7219866 disclose other known supporting devices presented to the Applicant for their consideration.
