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 .
Priority
Benefit of earlier filing date of 02/25/2022 of provisional application No. 63/314,226 is acknowledged as required by 35 U.S.C. 119.
Applicant has not complied with one or more conditions for receiving the benefit of an earlier filing date as follows: Figs. 10-13 related to tabletop shifting assembly mechanism does not have support in provisional application No. 63/314,226 and therefore does not benefit from the earlier filing date.
Claim Objections
Claims 1 and 14 objected to because of the following informalities:
Claim 1, line 7 and claim 14, line 8 “the height” should read --a height--.
Claim 14, “wherein the table tilt assembly is configured to wherein the table tilt assembly comprises” should read --wherein --.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.
Claim 12 is 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 12 recites the limitation “the pivot further comprises a second pivot pin, and wherein the pivot pin defines the pivot axis”. There is insufficient antecedent basis for this limitation in the claim. It is not clear if applicant intended to claim --the first pivot pin and the second pivot pin define the pivot axis--.
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.
Claims 1-3, 14 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Kritzer (US 20220402735 A1) in view of Eisenhauer (US 5839966 A).
Regarding claim 1, Kritzer teaches (reproduced and annotated Figs. below) a lift table (mobile scissor lift 1), comprising: (a) a base member (base frame 16); (b) a tabletop assembly (lift platform assembly 180), wherein the tabletop assembly comprises a table base (lift deck 184) and an adjustable top (tilting or tilt table 182), wherein the adjustable top is configured to pivot about a pivot axis relative to the table base such that the adjustable top is configured to define a plurality of angles relative to the table base (par. 0057: “a limited angular range in a fore and aft or side to side direction or a combination thereof”; Figs. 10-13); (c) a lift assembly configured to adjust the height of the tabletop assembly relative to the base member between a lowered configuration (not shown) and a raised configuration (shown in Fig. 1); and (d) a table tilt assembly (side tilt adjustment assembly or side tilt assembly 204) configured to drive the pivoting of the adjustable top relative to the table base among the plurality of angles (par. 0059; Figs. 10-13), In device of Kritzer table tilt assembly is not a jack screw mechanism as claimed.

Kritzer in Par. 0059 teaches “It is foreseen that other configurations of tilt mechanisms could be employed to adjustably tilt the tilt table 182 relative to the lift deck 184”.
Eisenhauer teaches (reproduced and annotated Figs. above) a tabletop assembly comprises a table base and an adjustable top, wherein the adjustable top is configured to pivot about a pivot axis relative to the table base such that the adjustable top is configured to define a plurality of angles relative to the table base; and (d) a table tilt assembly (table tilt assembly comprises nuts 52, a leveling screw 60 and counterbore 70 in which enlarged portion of the jack screw 60 is housed inside) configured to drive the pivoting of the adjustable top relative to the table base between the plurality of angles (par. 12-15), wherein the table tilt assembly comprises: (i) first and second threaded nuts (nuts 52; Fig. 2 shows 22 jack screws and nuts) fixed against rotation relative to the table base (par. 12: “prongs 58 are embedded into the top plate 12 and thus prevent the nut 52 from rotating within the top plate”, and (ii) first and second jack screws (par. 13: leveling screw 60) threadably coupled with the threaded nut; wherein the table tilt assembly is configured to retain the adjustable top in each of the plurality of angles.
It would have been obvious to one having ordinary skill in the art before effective filing date of the claimed invention to replace tilt adjustment mechanism of Kritzer with screw tilting adjustment mechanism of Eisenhauer. Doing so would allow any desired angle adjustment with a basic hand tool by using a simpler lifting mechanism.
Regarding claim 20, Kritzer teaches (reproduced and annotated Figs. above) the lift assembly comprises a scissor lift.
Claims 1-3, 14 and 19 are rejected under 35 U.S.C. 103 as being unpatentable over Zhou (CN 108373130 A) in view of Eisenhauer.

It would have been obvious to one having ordinary skill in the art before effective filing date of the claimed invention to replace single pivot of Lei with two separate pivots of Zhou; because these two pivot systems were art-recognized equivalents and one of ordinary skill in the art would have found it obvious to substitute two pivots for one pivot; also there is an absence of criticality to the number of these pins and there is also an absence of unexpected results.
Allowable Subject Matter
Claims 5, 15 and 17 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.
Claims 16 and 18 are allowable due to dependency on allowable claims 15 and 17.
