Office Action

§102 §103 §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 . Claim Objections Claim 1 is objected to because of the following informalities: Punctuation in Line 6. Replacing “fork group and” with “fork group, and” is suggested. Wording in Lines 9-10. Replacing “connected among lower portions” with “connected among a lower portion” is suggested. Punctuation in Line 10. Replacing “second support stand column and third” with “second support stand column, and third” is suggested. Punctuation in Line 15. Replacing “group and the second” with “group, and the second” is suggested. Punctuation in Line 17. Replacing “rear shear fork group and” with “rear shear fork group, and” is suggested. Punctuation in Line 29. Replacing “left and right” with “left, and right” is suggested. Punctuation in Line 31. Replacing “columns and” with “columns, and” is suggested. Punctuation in Line . Replacing “second bottom rod and” with “second bottom rod, and” is suggested. Claims 2-10 are objected to as being replete with punctuation and wording informalities that render the claims unclear, non-concise, and inexact. The informalities are too numerous to delineate. Claims 1-10 should be revised carefully to enable the intended interpretation. Examples of punctuation and wording objections are provided in the Objections to Claim 1, above. 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 1-10 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 term “bundle-shaped”. This term is not defined or described in the Drawings, Specification, or Claims, and is not a recognized term in the field of the claimed invention. Claims 1-10 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 limitations “end portions”, “two adjacent shear fork groups”, “each first and second stand column”. There is insufficient antecedent basis for these limitations in the claim. Claims 1-10 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. Claims 1-10 are replete with punctuation, wording, lack of antecedent basis issues that render the claims unclear and/or indefinite. The issues are too numerous to delineate. Claims 1-10 should be revised carefully to enable the intended interpretation. Examples of punctuation, wording, and lack of antecedent basis issues are provided in the rejections of Claim 1, under “Claim Rejections - 35 USC § 112”, above. 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. Claims 1 and 2 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Yang (US 20260159145 A1). [Note that prior art citations below are italicized and enclosed in brackets.] Regarding Claim 1, Yang teaches a bundle-shaped folded support frame, comprising a cart frame body, a wheel body assembly used for driving the cart frame body to move, and a pull handle assembly used for pushing and pulling the cart frame body [Yang Figs. 1-3], wherein the cart frame body comprises a front shear fork group, a rear shear fork group, a left shear fork group and a right shear fork group, and further comprises a first support stand column rotatably connected to end portions of the two adjacent shear fork groups, a second support stand column rotatably connected to the left shear fork group, a third support stand column rotatably connected to the right shear fork group, and an underframe structure connected among lower portions of each first support stand column, second support stand column and third support stand column [Yang Figs. 1 and 2]; the second support stand column and the third support stand column are arranged opposite to each other, the underframe structure comprises a first underframe assembly disposed between the lower portion of the first support stand column at two ends of the front shear fork group and the second support stand column and the third support stand column arranged opposite to each other, and a second underframe assembly disposed between the lower portion of the first support stand column at two ends of the rear shear fork group and the second support stand column and the third support stand column arranged opposite to each other [Yang Fig. 1]; and the first underframe assembly and the second underframe assembly are respectively provided with a first mounting member connected to the lower portion of each first support stand column, a second mounting member connected to the lower portion of the second support stand column, a third mounting member connected to the lower portion of the third support stand column, and a first connecting member, a first bottom rod of which two ends are rotatably connected to a lower side of the first connecting member and an upper side of the first mounting member respectively, a second bottom rod of which two ends are rotatably connected to the lower side of the first connecting member and an upper side of the second mounting member respectively, and a third bottom rod of which two ends are rotatably connected to the lower side of the first connecting member and an upper side of the third mounting member respectively, and when the cart frame body is driven to be folded, the front, rear, left and right shear fork groups deform to drive the first support stand columns, the second support stand columns and the third support stand columns to gather with each other, and the first bottom rod, the second bottom rod and the third bottom rod are gathered with each other to drive the first connecting member to move upwards [Yang Fig. 1]. Regarding Claim 2, Yang teaches the support frame according to claim 1, wherein the first connecting member is provided with four first connecting portions used for connecting the two first bottom rods, the second bottom rod, and the third bottom rod respectively, each first connecting portion comprises two first connecting side plates arranged opposite to each other in a longitudinal direction and a first connecting top plate connected between upper portions of the two first connecting side plates, the two first connecting side plates and the first connecting top plate surround to form a first connecting groove used for arranging an end portion of the bottom rod, and the first connecting side plates are rotatably connected to the bottom rod through a first connecting shaft [Yang Fig. 1]. Claim Rejections - 35 USC § 103 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 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. Claim 4 is rejected under 35 U.S.C. 103 as being unpatentable over Yang (US 20260159145 A1). [Note that prior art citations below are italicized and enclosed in brackets.] Regarding Claim 4, Yang teaches the support frame according to claim 2 wherein the first connecting member comprises a first connecting strip and a second connecting strip arranged perpendicular to each other in a crossed manner, a lower opening portion is arranged in the middle of the first connecting strip, an upper opening portion is arranged in the middle of the second connecting strip, the lower opening connecting portion is matched with the upper opening connecting portion in a buckled manner, after matching, a top surface of the first connecting strip and a top surface of the second connecting strip are located on the same plane and a bearing support surface used for abutting against the bottom of a cloth cover structure is formed, and the first connecting portions are formed at two ends of the first connecting strip and the second connecting strip respectively [Yang Fig. 1]. It is acknowledged that Yang’s first connecting member is comprised of one part and not comprised of a first connecting strip and a second connecting strip. It would however have been obvious to a person having ordinary skill in the art at the time of the claimed invention, to modify the one-part first connecting member of Yang to consist of two parts, as a matter of obvious design choice. It should be further noted that it has been held that constructing a formerly integral structure in various elements involves only routine skill in the art. Nerwin v. Erlichman, 168 USPQ 177 (BPAI 1969). Claim 10 is rejected under 35 U.S.C. 103 as being unpatentable over Yang (US 20260159145 A1) in view of Wu (CN 221794648 U). [Note that prior art citations below are italicized and enclosed in brackets.] Regarding Claim 10, Yang teaches a support frame but does not teach a cloth cover structure or quick-release buckles. Wu teaches a folding cart, comprising the support frame according to claim 1 and a cloth cover structure mounted in the cart frame body, a third connecting structure is fixedly connected to an upper portion of the first support stand column, and a fourth connecting structure is slidably connected to a lower portion of the first support stand column, upper portions of two ends of the front, rear, left, and right shear fork groups are rotatably connected to the third connecting structures arranged correspondingly, respectively, and lower portions of two ends of the front, rear, left, and right shear fork groups are rotatably connected to the fourth connecting structures arranged correspondingly, respectively; and a first mounting buckle arranged corresponding to the third connecting structure is arranged on the cloth cover structure, a first quick-release buckle detachably connected to the first mounting buckle is arranged on an inner side of the third connecting structure, and a second quick-release buckle used for connecting an accessory is arranged on an outer side of the third connecting structure [Wu Fig. 1; Wu Abstract: “The utility model claims a trolley, relating to the technical field of foldable trolley. The utility model comprises a side wall component, a cloth bag component, a bottom frame component and a quick-release buckle...four ends of the cloth bag component are provided with quick-release inserting buckles, the cloth bag component is connected with the upright post assembling component through the quick-release inserting buckles.”]. It would have been obvious for a person having ordinary skill in the art, before the effective filing date of the claimed invention, to have modified the support frame of Yang to include, with a reasonable expectation of success, a cloth cover structure and quick-release buckles in view of Wu. A person having ordinary skill in the art would have been motivated to combine Yang and Wu because this would have achieved the desirable result of enabling the cloth bag to be detached from the frame in order to be cleaned, as recognized by Wu [Wu Paragraph 0005: “detached for cleaning”]. Allowable Subject Matter Claim 3 is 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. [Note that prior art citations below are italicized and enclosed in brackets.] Regarding Claim 3, Yang teaches a support frame comprising a first connecting portion but does not teach a connecting groove, limiting plates, or abutting surfaces.
