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 are rejected under 35 U.S.C. 103 as being unpatentable over Kritzer (US 20220402735 A1) in view of Eisenhauer (US 5839966 A) and Carr (US 20190376539 A1).

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 (hereinafter modified lift table of Kritzer). Doing so would allow any desired angle adjustment with a basic hand tool by using a simpler lifting mechanism.

Allowable Subject Matter
Claims 14-16 and 18-20 are allowed.
The following is an examiner’s statement of reasons for allowance:
Claim 14 is allowed for disclosing “the adjustable top comprises a first receptacle that houses a portion of the first jack screw”. These limitations with other claimed limitations in a whole, make the instant invention neither anticipated nor rendered obvious by the best prior art in record.
The closest prior art to the claimed invention of claim 14 are Kritzer, Zhou and Eisenhauer.
Kritzer teaches (reproduced and annotated Figs. above) a lift table, 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), and wherein the adjustable top is configured to receive and support a fuel unit (par. 4-6: battery pack or battery of an electric vehicle) while defining each angle of the plurality of angles relative to the table base; (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 to (d) a table tilt assembly (side tilt adjustment assembly or side tilt assembly 204) configured to drive the pivoting of the adjustable top relative the table base about the pivot axis among the plurality of angles (par. 0059; Figs. 10-13), (par. 4-6: battery pack or battery of an electric vehicle).In device of Kritzer table tilt assembly is not jack screw mechanism. 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”.
Zhou teaches (reproduced and annotated Figs. above) a lift table, comprising: (a) a base member (1); (b) a tabletop assembly, wherein the 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; (c) a lift assembly configured to adjust the height of the tabletop assembly relative to the base member between a lowered configuration and a raised configuration; and (d) a table tilt assembly (assembly connecting the table base 2 and adjustable top 6) configured to drive the pivoting of the adjustable top relative to the table base about the pivot axis among the plurality of angles, Lift table of Zhou is used in “car maintenance industry” and therefore is capable of intended use of lifting and tilting a fuel unit.In device of Zhou, table tilt assembly is hydraulic jack and not jack screw mechanism.
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.
However Kritzer and Eisenhauer alone or in combination of Eisenhauer do not teach the claimed receptacle.
Claims 15-16 and 18-20 are allowed due to dependency on allowed claim 14.
Claim 5 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.
Response to Arguments
Applicant’s arguments with respect to amended claims 1 and 10 have been considered but are moot because the arguments do not apply to the combination of references being used in the current rejection as necessitate by amendments.
Conclusion
Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action.
