The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claim Interpretation
The following is a quotation of 35 U.S.C. 112(f):
(f) Element in Claim for a Combination. – An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof.
The following is a quotation of pre-AIA 35 U.S.C. 112, sixth paragraph:
An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof.
This application includes one or more claim limitations that do not use the word “means,” but are nonetheless being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, because the claim limitation(s) uses a generic placeholder that is coupled with functional language without reciting sufficient structure to perform the recited function and the generic placeholder is not preceded by a structural modifier. Such claim limitation(s) is/are: a scraper unit and a driving unit in claims 1 and 9, a motor overload protection unit in claims 4 and 9.
Because this/these claim limitation(s) is/are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, it/they is/are being interpreted to cover the corresponding structure described in the specification as performing the claimed function, and equivalents thereof.
If applicant does not intend to have this/these limitation(s) interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, applicant may: (1) amend the claim limitation(s) to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph (e.g., by reciting sufficient structure to perform the claimed function); or (2) present a sufficient showing that the claim limitation(s) recite(s) sufficient structure to perform the claimed function so as to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph.
Claims 1 and 9 recites:
“a scraper unit”. These limitations are interpreted under 35 USC 112(f) as scraper connector, two pneumatic slide tables, and a blade and equivalents thereof, to accomplish the claimed function (see at least [0028] of the specification of the instant application).
“ a driving unit”. These limitations are interpreted under 35 USC 112(f) as a mount, motor, rotating shafts, and sprockets and equivalents thereof, to accomplish the claimed function (see at least [0028] of the specification of the instant application).
Claims 4 and 9 recites “a motor overload protection unit”. These limitations are interpreted under 35 USC 112(f) as a rotating plate, trigger plate, vertically-arranged rod, and micro switches and equivalents thereof, to accomplish the claimed function (see at least [0028] of the specification of the instant application).
Claim Objections
Claims 4 and objected to because of the following informalities:
Claims 4-6, 9-10, and 15-18, recites "the frame" that should be "the machine frame".
Claim 4 recites “a motor" that should be "the motor".
Claim 7 and 10 recites “the rod" that should be “the vertically-arranged rod"
Appropriate correction is required.

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.
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
Claim 1 is rejected under 35 U.S.C. 102(a)(1) as being anticipated by Zhou (CN112452997A).
Regarding Claim 1, Zhou teaches A residue scraper (Fig. 1, [n0001]), comprising a machine frame (Ref. 32, Fig. 1), which is provided with a clamping unit (Ref. 39, fig. 1&2) for fastening a material holder (Ref. 39, Fig. 2);
a scraper unit (Ref. 46, 48-49, Fig. 1, [0034]) for cleaning residues on a to-be-cleaned surface of the material holder ([n0028]); and
a driving unit (Ref. 2, 410, 42, & 43, Fig. 1, [0034]) that drives the scraper unit to reciprocate along a long side direction (See annotated Fig. 1 below) of the material holder ([n0028]).

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 2 is rejected under 35 U.S.C. 103 as being unpatentable over Zhou as applied to claim 1 above, and further in view of Falk (2013/0081652).
Regarding Claim 2, Zhou teaches the limitations of claim 1, as described above, and further teaches wherein the machine frame is a rectangular frame (Fig. 1) a residue bucket (Ref. 5, Fig. 1, [0041]) is provided under the machine frame (Fig. 1), and the machine frame includes two long sides arranged in parallel and two short sides arranged in parallel (See annotated Fig. 1 below).
Zhou fails to explicitly teach a cover to protect the scraper unit, the driving unit, and the clamping unit. Falk teaches a cleaning apparatus and can be considered analogous art because it is reasonably pertinent to the problem faced by the inventor of moving a cleaning device laterally by a motor. Falk further teaches a cover to protect the entirety of the cleaning apparatus including a driving unit (Ref. 7, fig. 3) and a scraping unit (Ref. 11, Fig. 3). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date to modify the machine frame, as taught by Zhou, with a cover, as taught by Falk, to protect the moving components and contain any debris and fluid ([0031]).

Claim 3 is rejected under 35 U.S.C. 103 as being unpatentable over Zhou as modified as applied to claim 2 above, and further in view of Gorman (2008/0295265) and Lou (CN114248121A).
Regarding Claim 3, Zhou as modified teaches the limitations of claim 2, as described above, and further teaches wherein the scraper unit includes two skid rails (Ref. 46, Fig. 5), slide tables (Ref. 48, Fig. 6) arranged on the skid rails (46, Fig. 6), and a scraper (Ref. 49, Fig. 5) and arranged between two slide tables (Fig. 5-6), and the scraper includes a scraper connector (Fig. 6 annotated below) connecting to the two slide tables (48, Fig. 5-6) and blades (49, [n0039]) arranged on the scraper connector (Fig. 6) and located in parallel with two later faces of the short sides (Fig. 5-6).
Zhou as modified fails to explicitly teach the skid rails arranged on the two long sides respectively and a scraper located in parallel with the short sides. Gorman teaches a residue scraper and can be considered analogous art because it is within the same field of endeavor. Gorman further teaches the scraper (Fig. 1CC) having two skid rails (See annotated Fig. 1C below) arranged on the two long sides (Fig. 1c) respectively and a scraper (Ref. 29, Fig. 1C) located in parallel with the short sides (Fig. 1C), and the scraper include a scraper connector connecting to the two slide tables (Ref. 25, Fig. 1C) and blades (Ref. 9, Fig. 1C) arranged on the scraper connector and located in parallel with two later faces of the short sides (Fig. 1C). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date to modify the skid rails, as taught by Zhou as modified, to run along the two long sides with the scraper parallel to the short sides, as taught by Gorman, since such a modification would yield the predictable result of scraping off material from a substrate.
Zhou as modified further fails to explicitly teach pneumatic slide tables on the skid rails. Lou teaches a machine that is used to transfer linear movement of a head and can be considered analogous art because it is reasonably pertinent to the problem faced by the inventor to apply linear movement of a device. Lou teaches pneumatic slide tables (3072, Fig. 13) arranged on the skid rails (Fig. 14) to apply linear movement of a device (Fig. 13). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date to modify the slides, as taught by Zhou as modified, with the pneumatic slide tables, as taught by Lou, since such a modification would produce the predictable result of sliding on skid rails.

Claims 4 and 7-8 are rejected under 35 U.S.C. 103 as being unpatentable over Zhou as modified as applied to claim 2 above, and further in view of Gorman (2008/0295265) and Sheng (CN105173539A).
Regarding claim 4, Zhou as modified teaches the limitations of claim 2, as described above, and given the teaching of the rearrangement of skid rails along the long sides, Zhou further teaches wherein the driving unit includes rotating shaft (Ref. 410, Fig. 5), sprockets (Ref. 42, Fig. 5) arranged parallel with the short sides (Fig. 1&5), the sprockets mount on two ends of the long sides via bearing pedestals (Fig. 5), and the sprockets (42) are arranged at two ends of the rotating shaft (Fig. 5), and ring-shaped chains (Ref. 43, Fig. 5) are used to connect the sprockets ([n0031]), the scraper unit (4) is fastened to the ring-shaped chains (fig. 6), a motor (Ref. 2, Fig. 1) is suspended on one of the rotating shafts (Fig. 1).
Zhou as modified fails to explicitly teach two rotating shafts arranged parallel. Gorman teaches a residue scraper and can be considered analogous art because it is within the same field of endeavor. Gorman further teaches two rotating shafts (Fig. 1C&3) arranged in parallel (Fig. 3). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date to modify the sprockets, as taught by Zhou as modified, to have rotating shafts between the sprockets wherein two rotating shafts are arranged in parallel, as taught by Gorman, by duplication of parts and since such a modification would yield the predictable result of transferring movement of a motor to move a scraper along skid rails.
Zhou as modified further fails to explicitly teach the frame is provided with a motor overload protection unit. Sheng can be considered analogous art because it is reasonably pertinent to the problem faced by the inventor to use a motor to drive a device. Sheng further teaches a motor overload protection unit (Ref. 17, Fig. 2, [0050]). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date to modify the frame, as taught by Zhou, with a motor overload protection unit, as taught by Sheng, to prevent motor overloads and preventing component damage or accidents ([0004]).
Regarding claim 7, Zhou as modified teaches the limitations of claim 4, as described above, and Sheng further teaches wherein the motor overload protection unit (17)includes a rotating plate (Ref. 312, Fig. 3) fastened to the motor ([0049]) and a trigger plate (Ref. 316, Fig. 3) fastened to the frame (Fig. 3), the rotating plate is arranged perpendicular to the rotating shafts (318), the trigger plate is provided with a vertically-arranged rod (Ref. 312, Fig. 3, examiner notes the rod is has a dimension in a vertical direction and is vertically arranged), position limiting blocks (Ref. 310&306, Fig. 3) are arranged at both ends of the rod ([0042], Fig. 3) a connecting block (Ref. 307, Fig. 3) is provided on the rotating plate (Fig. 3), the connecting block is located between two position limiting blocks (Fig. 3), the connecting block is provided with a through hole for the rod to pass through (fig. 3, [0050]), springs (Ref. 309, Fig. 3) sleeved on the rod (fig. 3) are arranged between the position limiting blocks (310) and the connecting block (307, Fig. 3), the trigger plate is provided with two micro switches (Ref. 315, Fig. 3), the rotating plate (312) is provided with a check disc (Ref. 312, Fig. 3 right end of the rotating plate) for triggering the micro switches ([0055]), and the micro switches are electrically connected to the motor ([0021&0055]).
Regarding claim 8, Zhou as modified teaches the limitations of claim 4, as described above, and Sheng further teaches proximity switch (ref. 315, Fig. 3, [0055]) located at margin positions (Fig. 3) and are electrically connected to the motor to prevent over expenditure of the motor. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date to modify each long side of the frame, as taught by Zhou as modified, with the proximity sensor, as taught by Sheng, located at two margin positions to prevent motor overloads and preventing component damage or accidents ([0004]).
Claims 5-6 are rejected under 35 U.S.C. 103 as being unpatentable over Zhou as modified as applied to claim 2 above, and further in view of Jin (2014/0167342).
Regarding claim 5, Zhou as modified teaches the limitations of claim 2, as described above, and Zhou further teaches wherein the clamping unit includes clamps (Ref. 39, Fig. 2) arranged on two long sides (Ref. 39, Fig. 2 both long sides) and one short side of the frame (Fig. 1-2, Ref. 39, right side), and a position limiting plate (Ref. 39, Fig. 1-2, left side) arranged on the other short side (Fig. 2) and clamps face the inside of the frame (Fig. 2).
Zhou as modified fails to explicitly teach clamping cylinders and pistons of the clamping cylinders face the inside of the frame, and the pistons of the clamping cylinders are connected to L-shaped splints for snapping into the material holder. Jin can be considered analogous art because it is reasonably pertinent to the problem faced by the inventor to hold a substrate. Jin further teaches clamping cylinders (Ref. 371, Fig. 3) and pistons of the clamping cylinders (Ref. 371, Fig. 3) face the inside of the frame (Fig. 3), and the pistons of the clamping cylinders are connected to L-shaped splints (Ref. 373, Fig. 3) for snapping into the material holder (Ref. 311, Fig. 3). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date to replace the clamps, as taught by Zhou as modified, with the clamping cylinders attached to L-shaped brackets, as taught by Jin, since such a modification would yield the predictable result of holding a substate ([0059&0067]).
Regarding claim 6, Zhou as modified teaches the limitations of claim 5, as described above, and given the teachings of Zhou as modified having the clamping cylinders in place of the clamps, Zhou as modified further teaches wherein the clamping cylinders (Ref. 317, Fig. 3, Jin) on the long sides (Fig. 2, long sides, Zhou) are connected to the frame via L-shaped supports (Ref. 373, Fig. 3, Jin), and the L-shaped supports includes horizontal plates (Fig. 3 annotated below, Jin) on which the clamping cylinder are placed (Fig. 3), and vertical plates (Fig. 3 annotated below, Jin) connecting to the frame (Fig. 3).

Zhou as modified fails to explicitly teach two rotating shafts arranged parallel. Gorman teaches a residue scraper and can be considered analogous art because it is within the same field of endeavor. Gorman further teaches two rotating shafts (Fig. 1C&3) arranged in parallel (Fig. 3). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date to modify the sprockets, as taught by Zhou as modified, to have rotating shafts between the sprockets wherein two rotating shafts are arranged in parallel, as taught by Gorman, by duplication of parts and since such a modification would yield the predictable result of transferring movement of a motor to move a scraper along skid rails.
Zhou as modified further fails to explicitly teach the frame is provided with a motor overload protection unit. Sheng can be considered analogous art because it is reasonably pertinent to the problem faced by the inventor to use a motor to drive a device. Sheng further teaches a motor overload protection unit (Ref. 17, Fig. 2, [0050]). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date to modify the frame, as taught by Zhou, with a motor overload protection unit, as taught by Sheng, to prevent motor overloads and preventing component damage or accidents ([0004]).
