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 1-7, 9-11 and 13-15 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Abe (US 2009/0229310).
Regarding claim 1, Abe teaches a knitting tool (fig. 1, needle 10) comprising:

wherein the shank has, at every point along its length, a cross-section surface which extends orthogonally with respect to the longitudinal direction and along lateral and elevational directions (fig. 2 shows a set of cross section views of the needle 10 along lines 2a, 2b and 2c of fig. 1),
wherein each of the cross-sectional surfaces has a centroid, through which an imaginary center-of-gravity line runs that interconnects centroids of all the cross-sectional surfaces along the longitudinal direction (as the cross sections are rectangles, the imaginary center-of-gravity line is the middle line between the top surface and the bottom surface along the longitudinal direction of the needle),
wherein the shank has at least one functional portion (fig. 1, functional portion including float sections 22 and bridge 18) in which the imaginary center-of-gravity line has a varying height (fig. 1), and in which a height dimension of the cross sectional surface in the elevational direction is smaller at every point along a length of the at least one functional portion than a height of the shank within the at least one functional portion, wherein the height of the shank within the at least one functional portion is a distance, in the elevational direction, between a lowest point of the shank in the elevational direction and a highest point of the shank in the elevational direction within the at least one functional portion (annotated fig. 1 below), and
wherein the at least one functional portion has a length which is more than 20% of a length of the knitting tool (para. [0039], because the floating sections have longitudinal length L4 is between 10-60%, then the floating sections and bridge sections have a length which is more than 20% of the needle 10),
wherein the at least one functional portion has subsections (annotated fig. 1 below) in which an absolute value of a gradient of the imaginary center-of-gravity line is between 0 and ∞ (because the annotated subsections has an inclination between 0 and 90 degree with respect to the longitudinal direction, therefore, the slope of the subsections is between 0 and ∞).

Regarding claim 15, Abe teaches a knitting device (fig. 2 shows tool for circular knitting) comprising at least one needle slot (fig. 2, groove 19), which is configured to receive and, during operation, to guide a knitting tool (fig. 2, para. [0003], needle 10 is inserted into groove 19) and at least one knitting tool according claim 1.
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.
Claim 8 is rejected under 35 U.S.C. 103 as being unpatentable over Abe (US 2009/0229310), as applied to claim 7 above, and further in view of Fukuhara (US 4625527).
Regarding claim 8, Abe teaches the shank comprises lateral surfaces facing the lateral direction (fig. 2).
Abe does not teach at least one of the lateral surfaces is raised laterally relative to a majority of the least one functional portion at the position of at least one of the at least two local maxima.
However, in the same field of endeavor, Fukuhara teaches at least one of the lateral surfaces is raised laterally relative to a majority of the least one functional portion at the position of at least one of the at least two local maxima (fig. 4, at the local maxima 6, lateral surfaces are raised laterally relative to groove 10 as shown in fig. 3; column 3, lines 61-63, groove 10 comprises a majority of the functional portion at the position of the local maxima as the ratio of the width h of groove 10 to the width i of the needle shank is 0.5).
It would have been obvious to one of the ordinary skill in the art before the effective filing date of the invention to modify the lateral surfaces of Abe raised laterally relative to a majority of the least one functional portion at the position of at least one of the at least two local maxima as taught by Fukuhara for the benefit of reducing the weight of a knitting needle and thereby improving the shock absorbing of the shank of the needle (Fukuhara, column 1, lines 64-66).
Claim 12 is rejected under 35 U.S.C. 103 as being unpatentable over Abe (US 2009/0229310), as applied to claim 11 above, and further in view of Kopal (US 3875767).
Regarding claim 12, Abe does not teach an absolute value of the local gradient maximum of the top surface and/or an absolute value of the local gradient minimum of the bottom surface is between 0.57 and 2.75.
However, in the same field of endeavor, Kopal teaches an absolute value of the local gradient maximum of the top surface and/or an absolute value of the local gradient minimum of the bottom surface is between 0.57 and 2.75 (fig. 5, column 4, lines 7-10, the angle alpha formed by slanted portion 25 and by the back edge 26 is 50 degree or the absolute value of the gradient is tan (50 degree), which is equal 1.19).
It would have been obvious to one of the ordinary skill in the art before the effective filing date of the invention to modify the local gradient maximum of the top surface and/or a local gradient minimum of the bottom surface of Abe with the absolute value as suggested by Kopal so that the shank obtains a certain resiliency, which is capable of reducing the acceleration upon impact of the butt on a cam track face (Kopal, column 4, lines 10-12).
Claim 16 is rejected under 35 U.S.C. 103 as being unpatentable over Abe (US 2009/0229310), as applied to claim 15 above, and further in view of Su (US 7117692).
Regarding claim 16, Abe does not clearly teach a length of the at least one needle slot in the longitudinal direction of the knitting tool, a reach of the at least one functional portion in the longitudinal direction of the knitting tool, a magnitude of a stroke of a knitting movement of the knitting tool during knitting are mutually coordinated such that at least 80% of the reach of the at least one functional portion of the knitting tool, in the longitudinal direction remains within the at least one needle slot during knitting.
However, in the same field of endeavor, Su teaches a length of the at least one needle slot in the longitudinal direction of the knitting tool, a reach of the at least one functional portion in the longitudinal direction of the knitting tool (fig. 3A shows the needle 10 reaching for yarn 30, the needle 10 is in the needle slot of the guide plate 50), a magnitude of a stroke (annotated fig. 3A below) of a knitting movement of the knitting tool during knitting are mutually coordinated such that at least 80% of the reach of the at least one functional portion of the knitting tool, in the longitudinal direction remains within the at least one needle slot during knitting (annotated fig. 3A below, 100% of the annotated functional portion remains within the needle slot of the guide plate 50).
It would have been obvious to one of the ordinary skill in the art before the effective filing date of the invention to combine Abe with the teaching of Su that at least 80% of the reach of the at least one functional portion of the knitting tool, in the longitudinal direction remains within the at least one needle slot during knitting for the benefit of providing protection of the needle shank and keeping the functional portion out of the way of yarn knitting area.

Claim 17 is rejected under 35 U.S.C. 103 as being unpatentable over Abe (US 2009/0229310) and Su (US 7117692), as applied to claim 16 above, and further in view of Haug (US 2012/0006064).
Regarding claim 17, the modified structure Abe-Su does not teach an upper edge of the at least one needle slot is spaced in the elevational direction by a maximum of 0.5 mm from a highest point of a top surface of the shank facing a positive elevational direction of the knitting tool.
However, Abe teaches in fig. 2, the sinking length L2 of the floating section is 10% of the distance L from the bottom face to the upper face of the groove 19 (para. [0038]); and the floating sections 22 extend at a middle height that is lower than the bridge 18 (the highest point of a top surface of the shank)(para. [0037]). Then Abe teaches an upper edge of the needle slot is spaced in elevational direction less than 10% of the needle slot depth from a highest point of a top surface of the shank facing a positive elevational direction of the knitting tool.
In the same field of endeavor, Haug teaches needle slot depth is 3.7mm (para. [0004]).
It would have been obvious to one of the ordinary skill in the art before the effective filing date of the invention to combine the modified structure Abe-Su with the needle slot depth as taught by Haug because the knitting cylinder with guide channels and latch-type needles are known in the art (Haug, para. [0002], [0003], [0004]).
Then the modified structure Abe-Su-Haug teaches an upper edge of the at least one needle slot is spaced in the elevational direction by less than 0.37 mm (which is less than 0.5 mm) from a highest point of a top surface of the shank facing a positive elevational direction of the knitting tool.
Claim 18 is rejected under 35 U.S.C. 103 as being unpatentable over Abe (US 2009/0229310), Su (US 7117692) and Haug (US 2012/0006064),  as applied to claim 17 above, and further in view of Izumi (US 5327748).
Regarding claim 18, the modified structure Abe-Su-Haug teaches the knitting tool comprises a butt (Abe, fig. 1, butt 15), which is raised in a positive elevational direction relative to the at least one functional portion.
The modified structure Abe-Su-Haug does not teach the butt engages in a cam curve recess of the knitting device, and a highest point, in the positive elevational direction, of the top surface of the shank is spaced apart from the cam curve recess in the longitudinal direction.
However, in the same field of endeavor, Izumi teaches the butt (fig. 1, butt 1) engages in a cam curve recess (fig. 1, guide track 3) of the knitting device, and a highest point, in the positive elevational direction, of the top surface of the shank is spaced apart from the cam curve recess in the longitudinal direction (annotated fig. 1 below).
It would have been obvious to one of the ordinary skill in the art before the effective filing date of the invention to combine the modified structure Abe-Su-Haug with the teaching of Izumi that the butt engages in a cam curve recess of the knitting device, and a highest point, in the positive elevational direction, of the top surface of the shank is spaced apart from the cam curve recess in the longitudinal direction for the benefit of providing undulating path which the needle butt must follow as the butt is moved relative to the cam in a direction transverse to the longitudinal axis of the needle. Thus, the undulating sides of the cam track engage the needle butt and cause the knitting needle to move in a reciprocating fashion (Izumi, column 1, lines 24-30).

Claims 1-18 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 subsections have no portion that has a gradient of 0”. It is unclear how the subsections can have no portion that has a gradient of 0 because the subsections are not a line/lines. For the purpose of applying art, the limitation is interpreted that the subsections have no portion in which a gradient of the imaginary center-of-gravity line is 0.
Any remaining claims are rejected as depending from a rejected base claim.
In the art rejections below the claims have been treated as best understood by the examiner.
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 1-7, 9-11 and 13-15 are rejected to the degree of definiteness under 35 U.S.C. 102(a)(1) as being anticipated by Abe (US 2009/0229310).
Regarding claim 1, Abe teaches a knitting tool (fig. 1, needle 10) comprising:
a shank (fig. 1, shank 17), which extends essentially in a longitudinal direction in which the knitting tool is moved during knitting,
wherein the shank has, at every point along its length, a cross-sectional surface which extends orthogonally with respect to the longitudinal direction and along lateral and elevational directions (fig. 2 shows a set of cross section views of the needle 10 along lines 2a, 2b and 2c of fig. 1),
wherein each of the cross-sectional surfaces has a centroid, through which an imaginary center-of-gravity line runs that interconnects centroids of all the cross-sectional surfaces along the longitudinal direction (as the cross sections are rectangles, the imaginary center-of-gravity line is the middle line between the top surface and the bottom surface along the longitudinal direction of the needle),
wherein the shank has at least one functional portion (figs. 1, functional portion including float sections 22 and bridge 18) in which the imaginary center-of-gravity line has a varying height (fig. 1), and in which a height dimension of the cross-sectional surface in the elevational direction is smaller at every point a length of the at least one functional portion than a height of the shank within the at least one functional portion, wherein the height of the shank within the at least one functional portion is a distance, in the elevational direction, between a lowest point of the shank in the elevational direction and a highest point of the shank in the elevational direction with the at least one functional portion (annotated fig. 1 below), and
wherein the at least one functional portion has a length which is more than 20% of a length of the knitting tool (para. [0039], because the floating sections have longitudinal length L4 is between 10-60%, then the floating sections and bridge sections have a length which is more than 20% of the needle 10),
wherein the at least one functional portion has subsections (annotated fig. 1 below) in which an absolute value of a gradient of the imaginary center-of-gravity line is between 0 and ∞ (because the annotated subsections has an inclination between 0 and 90 degree with respect to the longitudinal direction, therefore, the slope of the subsections is between 0 and ∞);
wherein the subsections have no portion that has a gradient of 0 (annotated fig. 1 below, because the annotated subsections are angled subsections with respect to the horizontal line, the subsections have no portion that has a gradient of 0).

[0003], needle 10 is inserted into groove 19) and at least one knitting tool according claim 1.
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.
Claim 8 is rejected under 35 U.S.C. 103 as being unpatentable over Abe (US 2009/0229310), as applied to claim 7 above, and further in view of Fukuhara (US 4625527).
Regarding claim 8, Abe teaches the shank comprises lateral surfaces facing the lateral direction (fig. 2).
Abe does not teach at least one of the lateral surfaces is raised laterally relative to a majority of the least one functional portion at the position of at least one of the at least two local maxima.
However, in the same field of endeavor, Fukuhara teaches at least one of the lateral surfaces is raised laterally relative to a majority of the least one functional portion at the position of at least one of the at least two local maxima (fig. 4, at the local maxima 6, lateral surfaces are raised laterally relative to groove 10 as shown in fig. 3; column 3, lines 61-63, groove 10 comprises a majority of the functional portion at the position of the local maxima as the ratio of the width h of groove 10 to the width i of the needle shank is 0.5).
It would have been obvious to one of the ordinary skill in the art before the effective filing date of the invention to modify the lateral surfaces of Abe raised laterally relative to a majority of the least one functional portion at the position of at least one of the at least two local maxima as taught by Fukuhara for the benefit of reducing the weight of a knitting needle and thereby improving the shock absorbing of the shank of the needle (Fukuhara, column 1, lines 64-66).
Claim 12 is rejected under 35 U.S.C. 103 as being unpatentable over Abe (US 2009/0229310), as applied to claim 11 above, and further in view of Kopal (US 3875767).
Regarding claim 12, Abe does not teach an absolute value of the local gradient maximum of the top surface and/or an absolute value of the local gradient minimum of the bottom surface is between 0.57 and 2.75.
However, in the same field of endeavor, Kopal teaches an absolute value of the local gradient maximum of the top surface and/or an absolute value of the local gradient minimum of the bottom surface is between 0.57 and 2.75 (fig. 5, column 4, lines 7-10, the angle alpha formed by slanted portion 25 and by the back edge 26 is 50 degree or the absolute value of the gradient is tan (50 degree), which is equal 1.19).
It would have been obvious to one of the ordinary skill in the art before the effective filing date of the invention to modify the local gradient maximum of the top surface and/or a local gradient minimum of the bottom surface of Abe with the absolute value as suggested by Kopal so that the shank obtains a certain resiliency, which is capable of reducing the acceleration upon impact of the butt on a cam track face (Kopal, column 4, lines 10-12).
Claim 16 is rejected under 35 U.S.C. 103 as being unpatentable over Abe (US 2009/0229310), as applied to claim 15 above, and further in view of Su (US 7117692).
Regarding claim 16, Abe does not clearly teach a length of the at least one needle slot in the longitudinal direction of the knitting tool, a reach of the at least one functional portion in the longitudinal direction of the knitting tool, a magnitude of a stroke of a knitting movement of the knitting tool during knitting are mutually coordinated such that at least 80% of the reach of the at least one functional portion of the knitting tool, in the longitudinal direction remains within the at least one needle slot during knitting.
However, in the same field of endeavor, Su teaches a length of the at least one needle slot in the longitudinal direction of the knitting tool, a reach of the at least one functional portion in the longitudinal direction of the knitting tool (fig. 3A shows the needle 10 reaching for yarn 30, the needle 10 is in the needle slot of the guide plate 50), a magnitude of a stroke (annotated fig. 3A below) of a knitting movement of the knitting tool during knitting are mutually coordinated such that at least 80% of the reach of the at least one functional portion of the knitting tool, in the longitudinal direction remains within the at least one needle slot during knitting (annotated fig. 3A below, 100% of the annotated functional portion remains within the needle slot of the guide plate 50).
It would have been obvious to one of the ordinary skill in the art before the effective filing date of the invention to combine Abe with the teaching of Su that at least 80% of the reach of the at least one functional portion of the knitting tool, in the longitudinal direction remains within the at least one needle slot during knitting for the benefit of providing protection of the needle shank and keeping the functional portion out of the way of yarn knitting area.

Claim 17 is rejected under 35 U.S.C. 103 as being unpatentable over Abe (US 2009/0229310) and Su (US 7117692), as applied to claim 16 above, and further in view of Haug (US 2012/0006064).
Regarding claim 17, the modified structure Abe-Su does not teach an upper edge of the at least one needle slot is spaced in the elevational direction by a maximum of 0.5 mm from a highest point of a top surface of the shank facing a positive elevational direction of the knitting tool.
However, Abe teaches in fig. 2, the sinking length L2 of the floating section is 10% of the distance L from the bottom face to the upper face of the groove 19 (para. [0038]); and the floating sections 22 extend at a middle height that is lower than the bridge 18 (the highest point of a top surface of the shank)(para. [0037]). Then Abe teaches an upper edge of the needle slot is spaced in elevational direction less than 10% of the needle slot depth from a highest point of a top surface of the shank facing a positive elevational direction of the knitting tool.
In the same field of endeavor, Haug teaches needle slot depth is 3.7mm (para. [0004]).
It would have been obvious to one of the ordinary skill in the art before the effective filing date of the invention to combine the modified structure Abe-Su with the needle slot depth as taught by Haug because the knitting cylinder with guide channels and latch-type needles are known in the art (Haug, para. [0002], [0003], [0004]).
Then the modified structure Abe-Su-Haug teaches an upper edge of the at least one needle slot is spaced in the elevational direction by less than 0.37 mm (which is less than 0.5 mm) from a highest point of a top surface of the shank facing a positive elevational direction of the knitting tool.
Claim 18 is rejected under 35 U.S.C. 103 as being unpatentable over Abe (US 2009/0229310), Su (US 7117692) and Haug (US 2012/0006064), as applied to claim 17 above, and further in view of Izumi (US 5327748).
Regarding claim 18, the modified structure Abe-Su-Haug teaches the knitting tool comprises a butt (Abe, fig. 1, butt 15), which is raised in a positive elevational direction relative to the at least one functional portion.
The modified structure Abe-Su-Haug does not teach the butt engages in a cam curve recess of the knitting device, and a highest point, in the positive elevational direction, of the top surface of the shank is spaced apart from the cam curve recess in the longitudinal direction.
However, in the same field of endeavor, Izumi teaches the butt (fig. 1, butt 1) engages in a cam curve recess (fig. 1, guide track 3) of the knitting device, and a highest point, in the positive elevational direction, of the top surface of the shank is spaced apart from the cam curve recess in the longitudinal direction (annotated fig. 1 below).
It would have been obvious to one of the ordinary skill in the art before the effective filing date of the invention to combine the modified structure Abe-Su-Haug with the teaching of Izumi that the butt engages in a cam curve recess of the knitting device, and a highest point, in the positive elevational direction, of the top surface of the shank is spaced apart from the cam curve recess in the longitudinal direction for the benefit of providing undulating path which the needle butt must follow as the butt is moved relative to the cam in a direction transverse to the longitudinal axis of the needle. Thus, the undulating sides of the cam track engage the needle butt and cause the knitting needle to move in a reciprocating fashion (Izumi, column 1, lines 24-30).

Response to Arguments
Applicant' s arguments, dated 04/11/2024, with respect to the rejections of claims under 35 U.S.C 102 have been fully considered but they are not persuasive.
The Applicant argues that Abe fails to teach a knitting tool having a functional portion having a length which is more than 20% of a length of the knitting tool, wherein the functional portion has subsections in which an absolute value of a gradient of the imaginary center-of-gravity line is between 0 and ∞ and wherein the subsections have no portion that has a gradient of 0 (remarks, page 8, last para.).
In response, Abe teaches a functional portion which comprises float sections and a bridge, while the floating sections have longitudinal length L4 is between 10-60% of the knitting tool (para. [0039]), then the floating sections and bridge sections have a length which is more than 20% of the needle 10.
Further, claim 1 recites the at least one functional portion has subsections in which an absolute value of a gradient of the imaginary center-of-gravity line is between 0 and ∞ and wherein the subsections have no portion that has a gradient of 0. Therefore, Abe does teach the subsections as claimed (see the annotated angled subsections in the annotated Abe fig. 1 above).
The Applicant argues that Abe fails to teach at least one triangular and/or at least one wavelike recess.
In response, “wave” is defined as (1a) a moving ridge or swell on the surface of a liquid; (2c) an undulating line or streak or a pattern formed by such lines (www. merriam-webster.com/dictionary/wave). Therefore, Abe does teach at least one wavelike recess (see fig. 1 above).
The Applicant argues that the combination of Abe and Su does not teach claim 16 (page 10).
In response, claim 16 recites “a magnitude of a stroke of a knitting movement of the knitting tool during knitting...”, claim 16 does not recite “maximum magnitude of a stroke” as the Applicant argues.
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.  In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any extension fee pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action.  In no event, however, will the statutory period for reply expire later than SIX MONTHS from the date of this final action.
