Response to Arguments
Applicant’s arguments, filed 12/2/25, have been fully considered but are not persuasive.
Applicant argues that ‘First, the Office has not explained the proposed modification… For example, it is not clear whether the proposed modification involves replacing circular or band saws of the primary breakdown machine 124 of Barker2009 with saw blades or a set of upper and lower saw blade assemblies as taught by Kotesovec (e.g., upper and lower saw blade assembly A, Fig. 10), and replacing circular saw blades of gangsaw 128 with additional saw blades or another upper and lower saw blade assembly as taught by Kotesovec (e.g., upper and lower saw blade assembly B).’ (pages 8-9).
It is respectfully submitted that these issues were addressed in the last office action that states ‘One of ordinary skill in the art would have been motivated to do this modification, i.e. applying the 2 part cutting process as taught by Kotesovec, to the two cutting elements of Barker2009 (precut and saw module), to facilitate removing chips, particularly relatively long chips, as taught by Kotesovec [col. 3 lines 10-33, col. 6 lines 1-16]. In addition, it would be obvious to simply substitute the known circular saw of Kotesovec for any of the saws described by Barker2009, e.g. in the primary breakdown machine 124 (precut module), for the predictable result of a method for processing a workpiece that utilizes one or more circular saws’ (page 7). Applicant’s argument is there not persuasive.
Applicant argues that ‘Nor is it clear how the modified method/system could be further modified with the teachings of Hart - e.g., whether this would involve incorporating the vertical adjustment mechanism of Hart into the modified gang saw 128 to balance the cut depth between upper and lower saw blades - to achieve the claimed subject matter. Therefore, the Office has not provided a reasoned explanation as to why the invention as claimed would have been obvious to a person of ordinary skill’ (page 9).
It is respectfully submitted that Hart was merely cited for teaching that a desired depth of cut is associated with a first throughput speed through the saw module; and cutting the workpiece to thereby enable the saw module to cut the workpiece at an actual throughput speed that is equal to or greater than the first throughput speed’ (page 7 of the last office action) and no specific ‘adjustment mechanism’ was required to be attributed to Hart. Further, the broad claim recitations, e.g. merely cutting a workpiece at specific throughput speed, could be achieved with different types of saws, as would be understood by one having ordinary skill in the art. In addition, the rejection is based on the combined teachings of Barker2009, Kotesovec and Hart and "It is well-established that a determination of obviousness based on teachings from multiple references does not require an actual, physical substitution of elements." In re Mouttet, 686 F.3d 1322, 1332, 103 USPQ2d 1219, 1226 (Fed. Cir. 2012), see MPEP 2145 III, i.e. it is not necessary to physically combine each aspect of Barker2009, Kotesovec and Hart but ‘ Rather, the test is what the combined teachings of those references would have suggested to those of ordinary skill in the art.’ (MPEP 2145 III). Applicant’s argument is there not persuasive.
Applicant argues that ‘Assuming for the sake of argument that the proposed modification is to replace saws of the primary breakdown machine 124 and saws of the gangsaw 128 with the saw blades or upper and lower saw blade assemblies taught by Kotesovec, and to incorporate the vertical adjustment mechanism of Hart into the modified gangsaw 128, the proposed modification would not result in the subject matter of claim 21. The primary breakdown machine 124 and the gangsaw 128 would be cutting along different planes. (See e.g., Figs. 4-6 showing the primary breakdown machine cutting sideboards 406 from cant 428, forming flat faces along the cant; in Figs. 7-11, the flat faces are parallel or perpendicular to the cuts made by the gangsaw.) Thus, even if modified as suggested, the primary breakdown machine 124 and gangsaw 128 of Barker2009 would not cut along a "first portion" and a "remaining portion" of a "through-cut to be made longitudinally through the workpiece."’ (pages 9-10).
It is respectfully submitted that, as indicated above, it is not necessary to physically combine each and every aspect of Barker2009, Kotesovec and Hart but ‘Rather, the test is what the combined teachings of those references would have suggested to those of ordinary skill in the art.’ (MPEP 2145 III). Each of Barker2009, Kotesovec and Hart is only cited as teaching specific aspects of the claimed invention. Kotesovec is cited as teaching the first cut pattern defines a first portion of the through-cut; causing the precut module to cut only partially through the workpiece according to the first cut pattern; and causing the saw module to cut the workpiece along a remaining portion of the through-cut according to a second cut pattern to thereby sever a first piece from a remaining portion of the workpiece, wherein the remaining portion of the through-cut has a depth that is less than or equal to the desired depth of cut (page 6 of the last office action). Applicant’s argument is there not persuasive.
Applicant argues that ‘Barker2009 teaches that the primary breakdown machine 124 processes the log segments 204 to form cants (see paragraph [0075]). The primary breakdown machine must make through-cuts through the log segments to cut the log segments into cants (compare, e.g., Fig. 3 with Figs. 4-6). As such, operating the modified primary breakdown machine "to cut only partially through" the log or cant would be counterintuitive, as it would presumably result in the incomplete processing of the log segments into cants’ (page 10).
It is respectfully submitted that, as detailed in the last office action, the combination of Barker2009, Kotesovec and Hart would result in a through cut based on the teaching of Kotesovec that describe progressively deeper cuts resulting in a through cut [see Fig. 10 and the explanation in col. 2 lines 45-55, Figs. 1-3]. Applicant’s argument is there not persuasive.
Applicant argues that ‘However, even in combination, the cited references do not teach or suggest determining a "first cut pattern" - which is configured to be implanted by primary breakdown machine 124 (equated by the Office with the "precut module" - based on a "cut solution" for the "workpiece" and a "desired depth of cut" for gangsaw 128 (equated by the Office with the "saw module"). Even if the dashed horizontal lines shown in Fig. 10 of Kotesovek could be fairly equated with a "desired depth of cut" for saw assemblies A and B as asserted by the Office (this is not conceded), and the saw assembly(ies) of Fig. 10 were somehow incorporated into the gangsaw 128, there is simply no teaching or suggestion in the combined references of determining a cut pattern/or the primary breakdown machine based on both a "cut solution" for a workpiece and a "desired depth of cut" for the gangsaw 128’ (pages 10-11).
It is respectfully submitted Barker teaches a cutting pattern/solution because Barker shows a cross-sectional view of a sawn cant showing the optimized cutting pattern/solution [0030, Figs. 7-11] and Kotesovec shows various cutting patterns for saws [col. 3 lines 10-33, Figs. 7, 9-11; col. 5 lines 31-50, Fig. 10]. Note that the claims, including cutting patterns/solutions, are given their broadest reasonable interpretation in accord with MPEP 2111. Also note that neither primary breakdown machines nor gangsaws are specifically claimed. And, it is not necessary to physically combine each and every element of Barker2009, Kotesovec and Hart but ‘Rather, the test is what the combined teachings of those references would have suggested to those of ordinary skill in the art.’ (MPEP 2145 III). Applicant’s argument is there not persuasive.
Applicant’s argument that ‘Hart cannot remedy the deficiencies of Barker2009 and Kotesovek. Even if Hart's vertical adjustment device for a saw box were to be incorporated in some way into the modified gangsaw 128, Hart still cannot be said to teach or suggest determining a "first cut pattern" for the primary breakdown machine 124 based on both a "cut solution" for a workpiece and a "desired depth of cut" for the gangsaw 128’ (page 11) is moot because Hart is not cited as teaching these features.
Applicant’s comments on independent claim 31 and the respective dependent claims (page 11) are moot given the continued rejection of claim 21.
Applicant’s comments regarding Millwide and Barker2013 (page 11) are moot because neither Millwide nor Barker2013 is cited as teaching elements of independent claims 21 and 31.
For at least these reasons, the rejection of the claims is maintained.
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 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 of this title, 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 set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied 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.
Claims 21, 26, 30-31, 36 and 40 are rejected under 35 U.S.C. 103 as being unpatentable over Barker U.S. Patent Publication No. 20090255607 (hereinafter Barker2009) in view of Kotesovec et al. U.S. Patent No. 3347289 (hereinafter Kotesovec) and further in view of Hart U.S. Patent Publication No. 20060021677 (hereinafter Hart).
Regarding claim 21, Barker2009 teaches a method of processing a workpiece to obtain a desired cut product, wherein the workpiece is a log or a cant and the desired cut product is a board [0075, Figs. 1-11 — log segments 204 may then be transported the rest of the way to the primary breakdown machine 124. The primary breakdown machine 124 processes the log segments 204 to produce cants and may include chip heads for removing slab wood as well as one or more saws (e.g., round saws or band saws) for sawing sideboards from the cants.], the method comprising:
determining a first cut pattern based at least on a cut solution for the workpiece, wherein the first cut pattern is configured to be implemented by a precut module with at least one cutting member located upstream of the saw module [0068-0078, Fig. 1 — the functionality of the primary breakdown computer optimizer may be incorporated into the computing device 116, and the log segment scan zone 106 may provide image data to the computing device 116 for the primary breakdown optimization; 0030, Figs. 7-11— cross-sectional view of a sawn cant showing the optimized cutting pattern/solution; 0075, Fig. 1 — The primary breakdown machine 124 (precut module upstream of gangsaw 128 (saw module)) processes the log segments 204 to produce cants and may include chip heads for removing slab wood as well as one or more saws (e.g., round saws or band saws) for sawing sideboards from the cants.; 0096, Fig. 1 — After processing at the primary breakdown machine 124, the cants 428 may be transported for further processing at a gangsaw 128 (saw module)],
wherein the cutting members are profiling heads or saws [0075 — The primary breakdown machine 124 processes the log segments 204 to produce cants and may include chip heads for removing slab wood as well as one or more saws (e.g., round saws or band saws) for sawing sideboards from the cants.],
the cut solution defines a through-cut to be made longitudinally through the workpiece and the first cut pattern defines a through-cut [0030, Figs. 7-11— cross-sectional view of a sawn cant showing the optimized longitudinal through cuts] and cut is associated with a first throughput speed through the saw module; to thereby enable the saw module to cut the workpiece at an actual throughput speed that is equal to or greater than the first throughput speed [0089 — the primary breakdown computer optimizer to adjust the speed at which log segments 204 are transported through the primary breakdown machine 124 (saw module) — the throughput speed through the first saw module is equal to the actual throughput speed].
But Barker2009 fails to clearly specify a first cut pattern based at least on a desired depth of cut for a saw module; a pair of cutting members are circular saw; and the first cut pattern defines a first portion of the through-cut and the desired depth of cut is associated with a first throughput speed through the saw module; causing the precut module to cut only partially through the workpiece according to the first cut pattern; and causing the saw module to cut the workpiece along a remaining portion of the through-cut according to a second cut pattern to thereby sever a first piece from a remaining portion of the workpiece, wherein the remaining portion of the through-cut has a depth that is less than or equal to the desired depth of cut.
However, Kotesovec teaches a first cut pattern based at least on a desired depth of cut for a saw module [col. 5 lines 31-50, Fig. 10 — a sawing apparatus may be provided, as in FIG. 10, which apparatus is operative to successively produce the saw kerfs of incrementally increasing depth during a single pass of the log or timber 1 through such sawing apparatus. More specifically, the apparatus illustrated in FIG. 10 includes three sets of upper and lower saw blade assemblies, as indicated generally at A, B and C, with each set of saw blade assemblies being adjustably mounted in the manner described above with respect to FIG. 9 so that the successively located saw blade assemblies at A, B and C can be adjusted to make successively increasing depths of cuts in the log or timber 1 during a single pass of the latter through the sawing apparatus — Desired depth of cut is marked (dashed horizontal lines) for saw blade assemblies A and B]; a pair of cutting members are circular saws [col. 3 lines 10-33, Figs. 7, 9-11 — rotary saw blade 12 and the other circular saw blades shown]; and the first cut pattern defines a first portion of the through-cut; causing the precut module to cut only partially through the workpiece according to the first cut pattern; and causing the saw module to cut the workpiece along a remaining portion of the through-cut according to a second cut pattern to thereby sever a first piece from a remaining portion of the workpiece, wherein the remaining portion of the through-cut has a depth that is less than or equal to the desired depth of cut [col. 5 lines 31-50, Fig. 10 — a sawing apparatus may be provided, as in FIG. 10, which apparatus is operative to successively produce the saw kerfs of incrementally increasing depth during a single pass of the log or timber 1 through such sawing apparatus. More specifically, the apparatus illustrated in FIG. 10 includes three sets of upper and lower saw blade assemblies, as indicated generally at A, B and C, with each set of saw blade assemblies being adjustably mounted in the manner described above with respect to FIG. 9 so that the successively located saw blade assemblies at A, B and C can be adjusted to make successively increasing depths of cuts in the log or timber 1 during a single pass of the latter through the sawing apparatus].
Barker2009 and Kotesovec are analogous art because they are from the same field of endeavor. They relate to lumber processing systems.
Therefore at the time the invention was made, it would have been obvious to a person of ordinary skill in the art to modify the above method for processing a workpiece, as taught by Barker2009, by incorporating the above limitations, as taught by Kotesovec.
One of ordinary skill in the art would have been motivated to do this modification, i.e. applying the 2 part cutting process as taught by Kotesovec, to the two cutting elements of Barker2009 (precut and saw module), to facilitate removing chips, particularly relatively long chips, as taught by Kotesovec [col. 3 lines 10-33, col. 6 lines 1-16]. In addition, it would be obvious to simply substitute the known circular saw of Kotesovec for any of the saws described by Barker2009, e.g. in the primary breakdown machine 124 (precut module), for the predictable result of a method for processing a workpiece that utilizes one or more circular saws.
But the combination of Barker2009 and Kotesovec fails to clearly specify the desired depth of cut is associated with a first throughput speed through the saw module.
However, Hart teaches the desired depth of cut is associated with a first throughput speed through the saw module; and cutting the workpiece to thereby enable the saw module to cut the workpiece at an actual throughput speed that is equal to or greater than the first throughput speed [0026-0027 — the feed speed to process an 8 inch cant may be in the order of 33% faster when saw box 5 is vertically adjusted to equalize the depth of cut between bottom arbor saw 10a and top arbor saw 15a… if the thickness of the cant is 10 inches, saw box 5 may be adjusted vertically downwards by 1 inch such that bottom arbor saw 10a would process the bottom 5 inches of the cant (as opposed to 6 inches if saw box 5 is not vertically adjusted), top arbor saw 15a would process the top 5 inches of the cant (as opposed to 4 inches if saw box 5 is not vertically adjusted), and the feed speed would be 20% faster if saw box 5 is vertically adjusted. Because of the uneven distribution of horsepower usage between bottom arbor saw 10a and top arbor saw 15a, the efficiency of the feed speed is compromised if saw box 5 is in a position such that the depth of cut of bottom arbor saw 10a is disproportionate to the depth of cut of top arbor saw 15a. By equally sharing the depth of cut required to process work piece 20 between top arbor saw 15a and bottom arbor saw 10a, the horsepower required to process work piece 20 is also equally distributed between bottom arbor saw 10a and top arbor 15, thereby increasing the feed speed; 0009-0012 — The object of the present invention is to provide a double arbor gang saw adapted to distribute the usage of horsepower connected to the bottom arbor saws and the top arbor saws such that the feed speed may be increased to achieve greater throughput].
Barker2009, Kotesovec and Hart are analogous art because they are from the same field of endeavor. They relate to lumber processing systems.
Therefore at the time the invention was made, it would have been obvious to a person of ordinary skill in the art to modify the above method for processing a workpiece, as taught by the combination of Barker2009 and Kotesovec, by incorporating the above limitations, as taught by Hart.
One of ordinary skill in the art would have been motivated to do this modification to take account of the depth of the cut in order to obtain an optimal feed/throughput speed, as suggested by Hart [0009-0012, 0026-0027].
Regarding claim 26, the combination of Barker2009, Kotesovec and Hart teaches all the limitations of the base claims as outlined above.
Further, Kotesovec teaches the precut module has a pair of circular saws [col. 3 lines 10-33, Figs. 7, 9-11 — rotary saw blades 12 and the other circular saw blades shown], the first portion of the through-cut has a first section along one side of the workpiece and another section along an opposite side of the workpiece, and the remaining portion of the through-cut is between said sections [col. 5 lines 31-50, Fig. 10 — a sawing apparatus may be provided, as in FIG. 10, which apparatus is operative to successively produce the saw kerfs of incrementally increasing depth during a single pass of the log or timber 1 through such sawing apparatus. More specifically, the apparatus illustrated in FIG. 10 includes three sets of upper and lower saw blade assemblies, as indicated generally at A, B and C, with each set of saw blade assemblies being adjustably mounted in the manner described above with respect to FIG. 9 so that the successively located saw blade assemblies at A, B and C can be adjusted to make successively increasing depths of cuts in the log or timber 1 during a single pass of the latter through the sawing apparatus — Upper and lower saw blade assemblies A leave a remaining portion of the through-cut between the upper and lower cuts to be cut by the other rotary saws].
Therefore at the time the invention was made, it would have been obvious to a person of ordinary skill in the art to modify the above method for processing a workpiece, as taught by the combination of Barker2009, Kotesovec and Hart, by incorporating the above limitations, as taught by Kotesovec.
One of ordinary skill in the art would have been motivated to do this modification to facilitate removing chips, particularly relatively long chips, as taught by Kotesovec [col. 3 lines 10-33, col. 6 lines 1-16]. In addition, it would be obvious to simply substitute the known circular saw of Kotesovec for the saw of Barker2009 for the predictable result of a method for processing a workpiece that utilizes a circular saw.
Regarding claim 30, the combination of Barker2009, Kotesovec and Hart teaches all the limitations of the base claims as outlined above.
Further, Kotesovec teaches determining the first cut pattern includes comparing a total depth of the through-cut to the desired depth of cut, and wherein the first portion of the through-cut is equal to or greater than a difference between the total depth and the desired depth of cut [col. 5 lines 31-50, Fig. 10 — a sawing apparatus may be provided, as in FIG. 10, which apparatus is operative to successively produce the saw kerfs of incrementally increasing depth during a single pass of the log or timber 1 through such sawing apparatus. More specifically, the apparatus illustrated in FIG. 10 includes three sets of upper and lower saw blade assemblies, as indicated generally at A, B and C, with each set of saw blade assemblies being adjustably mounted in the manner described above with respect to FIG. 9 so that the successively located saw blade assemblies at A, B and C can be adjusted to make successively increasing depths of cuts in the log or timber 1 during a single pass of the latter through the sawing apparatus — The various cuts are equal to a difference between the total depth and the desired depth of the other cuts.].
Therefore at the time the invention was made, it would have been obvious to a person of ordinary skill in the art to modify the above method for processing a workpiece, as taught by the combination of Barker2009, Kotesovec and Hart, by incorporating the above limitations, as taught by Kotesovec.
One of ordinary skill in the art would have been motivated to do this modification to facilitate removing chips, particularly relatively long chips, as taught by Kotesovec [col. 3 lines 10-33, col. 6 lines 1-16].
Regarding claim 31, Barker2009 teaches a system for processing a workpiece to obtain a desired cut product, wherein the desired cut product is a log or a cant and the desired cut product is a board [0048, Fig. 1 — a schematic view of an example sawmill 100 incorporating a system 102; 0075, Figs. 1-11 — log segments 204 may then be transported the rest of the way to the primary breakdown machine 124. The primary breakdown machine 124 processes the log segments 204 to produce cants and may include chip heads for removing slab wood as well as one or more saws (e.g., round saws or band saws) for sawing sideboards from the cants.], the system comprising:
a precut module having at least one cutting member, wherein the cutting members are profiling heads or saws [0075, Fig. 1 — The primary breakdown machine 124 (precut module upstream of gangsaw 128 (saw module)) processes the log segments 204 to produce cants and may include chip heads for removing slab wood as well as one or more saws (e.g., round saws or band saws) for sawing sideboards from the cants.; 0096, Fig. 1 — After processing at the primary breakdown machine 124, the cants 428 may be transported for further processing at a gangsaw 128 (saw module)];
a saw module downstream of the precut module [0075, Fig. 1 — The primary breakdown machine 124 (precut module upstream of gangsaw 128 (saw module)) processes the log segments 204 to produce cants and may include chip heads for removing slab wood as well as one or more saws (e.g., round saws or band saws) for sawing sideboards from the cants.; 0096, Fig. 1 — After processing at the primary breakdown machine 124, the cants 428 may be transported for further processing at a gangsaw 128 (saw module)]; and
an optimizer operatively coupled with the precut module, the optimizer programmed with instructions operable, upon execution by one or more computer processors of the optimizer, [0068-0078, Fig. 1 — the functionality of the primary breakdown computer optimizer may be incorporated into the computing device 116, and the log segment scan zone 106 may provide image data to the computing device 116 for the primary breakdown optimization; 0030, Figs. 7-11— cross-sectional view of a sawn cant showing the optimized cutting pattern/solution; 0124-0127 — computer system configurations, including handheld devices, multiprocessor systems, microprocessor-based… processing unit 1906],
wherein the cut solution defines a through-cut to be made longitudinally through the workpiece, and the first cut pattern defines a through-cut [0030, Figs. 7-11— cross-sectional view of a sawn cant showing the optimized longitudinal through cuts] and a cut is associated with a first throughput speed through the saw module; to thereby enable the saw module to cut the workpiece at an actual throughput speed that is equal to or greater than the first throughput speed [0089 — the primary breakdown computer optimizer to adjust the speed at which log segments 204 are transported through the primary breakdown machine 124 (saw module) — the throughput speed through the first saw module is equal to the actual throughput speed].
But Barker2009 fails to clearly specify a first cut pattern based at least on desired depth of cut for a saw module; a pair of cutting members are circular saws; and the first cut pattern defines a first portion of the through-cut and the desired depth of cut is associated with a first throughput speed through the saw module; causing the precut module to cut only partially through the workpiece according to the first cut pattern; and causing the saw module to cut the workpiece along a remaining portion of the through-cut according to a second cut pattern to thereby sever a first piece from a remaining portion of the workpiece, wherein the remaining portion of the through-cut has a depth that is less than or equal to the desired depth of cut.
However, Kotesovec teaches a first cut pattern based at least on a cut solution for the workpiece and a desired depth of cut for a saw module [col. 5 lines 31-50, Fig. 10 — a sawing apparatus may be provided, as in FIG. 10, which apparatus is operative to successively produce the saw kerfs of incrementally increasing depth during a single pass of the log or timber 1 through such sawing apparatus. More specifically, the apparatus illustrated in FIG. 10 includes three sets of upper and lower saw blade assemblies, as indicated generally at A, B and C, with each set of saw blade assemblies being adjustably mounted in the manner described above with respect to FIG. 9 so that the successively located saw blade assemblies at A, B and C can be adjusted to make successively increasing depths of cuts in the log or timber 1 during a single pass of the latter through the sawing apparatus — Desired depth of cut is marked (dashed horizontal lines) for saw blade assemblies A and B]; a pair of cutting members are circular saws [col. 3 lines 10-33, Figs. 7, 9-11 — rotary saw blade 12 and the other circular saw blades shown]; and the first cut pattern defines a first portion of the through-cut; causing the precut module to cut only partially through the workpiece according to the first cut pattern; and causing the saw module to cut the workpiece along a remaining portion of the through-cut according to a second cut pattern to thereby sever a first piece from a remaining portion of the workpiece, wherein the remaining portion of the through-cut has a depth that is less than or equal to the desired depth of cut [col. 5 lines 31-50, Fig. 10 — a sawing apparatus may be provided, as in FIG. 10, which apparatus is operative to successively produce the saw kerfs of incrementally increasing depth during a single pass of the log or timber 1 through such sawing apparatus.

Barker2009 and Kotesovec are analogous art because they are from the same field of endeavor. They relate to lumber processing systems.
Therefore at the time the invention was made, it would have been obvious to a person of ordinary skill in the art to modify the above system for processing a workpiece, as taught by Barker2009, by incorporating the above limitations, as taught by Kotesovec.

But the combination of Barker2009 and Kotesovec fails to clearly specify the desired depth of cut is associated with a first throughput speed through the saw module.
However, Hart teaches the desired depth of cut is associated with a first throughput speed through the saw module; and cutting the workpiece to thereby enable the saw module to cut the workpiece at an actual throughput speed that is equal to or greater than the first throughput speed [0026-0027 — the feed speed to process an 8 inch cant may be in the order of 33% faster when saw box 5 is vertically adjusted to equalize the depth of cut between bottom arbor saw 10a and top arbor saw 15a… if the thickness of the cant is 10 inches, saw box 5 may be adjusted vertically downwards by 1 inch such that bottom arbor saw 10a would process the bottom 5 inches of the cant (as opposed to 6 inches if saw box 5 is not vertically adjusted), top arbor saw 15a would process the top 5 inches of the cant (as opposed to 4 inches if saw box 5 is not vertically adjusted), and the feed speed would be 20% faster if saw box 5 is vertically adjusted.
