Office Action

§103
DETAILED ACTION 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 . Status of Claims This office action is in reply to the Response filed on October 10, 2025. No claims have been amended. No additional claims have been added. No further claims have been cancelled. Claim interpretation previously made under 35 USC 112(f) is maintained. The previous 35 U.S.C. 103 rejection has been withdrawn however a new rejection is presented herewith and is discussed in greater detail below. Claims 1-15 are currently pending and have been fully examined. 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 1-15 are rejected under 35 U.S.C. 103 as being unpatentable over Bendorf (2020/0384613) in view Blumenthal et al. (2019/0076994) and/or Wu (2015/0283681). In reference to claims 1 and 10, Bendorf discloses a tool having first (105) and second (110) handles and first (115) and second (120) jaws (Figure 1), the tool comprising: a first jaw pivot (145) pivotably coupling the second jaw to the first handle (Figure 1); a second jaw pivot (150) pivotably coupling the second jaw to the second handle (Figure 1); a center link (147) coupled to the first handle at a slideable pivot (i.e. between 185 and 175, Figure 1) and coupled to the second handle at a link pivot (227, Figure 3); and a release lever (187) rotatably coupled to the second handle and including an abutment (192, Figure 2) protruding substantially perpendicularly with respect to a longitudinal length of the release lever, and the abutment is adapted to interact with the center link (i.e. at 190) to cause the first and second jaws to release from a locked state (paragraph 16). Bendorf lacks specifically disclosing that, a first distance between the second jaw pivot and the link pivot is about 34% to about 70% of a second distance between the second jaw pivot and the first jaw pivot. However, Bendorf does disclose that, “While particular embodiments have been shown and described, it will be apparent to those skilled in the art that changes and modifications may be made without departing from the broader aspects of the inventors' contribution.” (paragraph 20). In addition, Blumenthal et al. teach that it is old and well known in the art at the time the invention was made to provide a similar wrench (Figure 1) where the dimensions of the tool can be altered (see paragraph 63 disclosing that, "Further modifications and alternative embodiments of various aspects of the invention will be apparent to those skilled in the art in view of this description…Although only a few embodiments have been described in detail in this disclosure, many modifications are possible (e.g., variations in sizes, dimensions, structures, shapes and proportions of the various elements, values of parameters, mounting arrangements, use of materials, colors, orientations, etc.) without materially departing from the novel teachings and advantages of the subject matter described herein."). Thus, as such the dimensions of the tool (i.e. including the first and second distances) are considered as being a result effective variable in that changing the dimensions also changes the grasping force (see paragraph 5) and/or the torque increasing jaw design (see paragraph 2). Furthermore, Wu also teaches that it is old and well known in the art at the time the invention was made to provide a similar wrench (Figure 1) having a first distance (L2) located between a second jaw pivot (C2) and a link pivot (C3) and a second distance (see figure below) located between the second jaw pivot and a first jaw pivot (C1). The distances being selected “so as to be effort-saving” (see paragraphs 3, 27 and 31). PNG media_image1.png 310 640 media_image1.png Greyscale Thus, in view of Blumenthal et al. and/or Wu, the first and second distances are considered as being a result effective variable because changing the first and second distances also changes the changes the grasping force (see paragraph 5 of Blumenthal et al.) and/or the torque increasing jaw design (see paragraph 2 of Blumenthal et al.) and/or the “effort-saving” (see paragraphs 3, 27 and 31 of Wu). Further, it appears that one of ordinary skill in the art would have had a reasonable expectation of success in modifying the Bendorf device to have; a first distance between the second jaw pivot and the link pivot is about 34% to about 70% of a second distance between the second jaw pivot and the first jaw pivot, as it involves only adjusting the dimensions of the first and second distances for the reasons previously discussed above. Therefore, it would have been obvious to one having ordinary skill in the art at the time of the invention to modify the device of Bendorf with the first distance between the second jaw pivot and the link pivot being about 34% to about 70% of a second distance between the second jaw pivot and the first jaw pivot, as a matter of routine optimization, since it has been held that “where the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation." In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955). In the instant case, the device of Bendorf would not operate differently with the claimed dimensions of the first and second distances indicated above and since the device is used for gripping an object (see paragraph 2 of Bendorf), the device would function appropriately having the claimed dimensions indicated above. Further, it appears that applicant places no criticality on the ranges claimed, indicating simply that the dimensions of the first and second distances are “about” the claimed ranges (see claim 1). In reference to claims 2 and 11, Bendorf lacks specifically disclosing that, the first distance is about 43.5% of the second distance However, Bendorf does disclose that, “While particular embodiments have been shown and described, it will be apparent to those skilled in the art that changes and modifications may be made without departing from the broader aspects of the inventors' contribution.” (paragraph 20). In addition, Blumenthal et al. teach that it is old and well known in the art at the time the invention was made to provide a similar wrench (Figure 1) where the dimensions of the tool can be altered (see paragraph 63 disclosing that, "Further modifications and alternative embodiments of various aspects of the invention will be apparent to those skilled in the art in view of this description…Although only a few embodiments have been described in detail in this disclosure, many modifications are possible (e.g., variations in sizes, dimensions, structures, shapes and proportions of the various elements, values of parameters, mounting arrangements, use of materials, colors, orientations, etc.) without materially departing from the novel teachings and advantages of the subject matter described herein."). Thus, as such the dimensions of the tool (i.e. including the first and second distances) are considered as being a result effective variable in that changing the dimensions also changes the grasping force (see paragraph 5) and/or the torque increasing jaw design (see paragraph 2). Furthermore, Wu also teaches that it is old and well known in the art at the time the invention was made to provide a similar wrench (Figure 1) having a first distance (L2) located between a second jaw pivot (C2) and a link pivot (C3) and a second distance (see figure above) located between the second jaw pivot and a first jaw pivot (C1). The distances being selected “so as to be effort-saving” (see paragraphs 3, 27 and 31). Thus, in view of Blumenthal et al. and/or Wu, the first and second distances are considered as being a result effective variable because changing the first and second distances also changes the changes the grasping force (see paragraph 5 of Blumenthal et al.) and/or the torque increasing jaw design (see paragraph 2 of Blumenthal et al.) and/or the “effort-saving” (see paragraphs 3, 27 and 31 of Wu). Further, it appears that one of ordinary skill in the art would have had a reasonable expectation of success in modifying the Bendorf device to have; the first distance being about 43.5% of the second distance, as it involves only adjusting the dimensions of the first distance for the reasons previously discussed above. Therefore, it would have been obvious to one having ordinary skill in the art at the time of the invention to modify the device of Bendorf with the first distance being about 43.5% of the second distance, as a matter of routine optimization, since it has been held that “where the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation." In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955). In the instant case, the device of Bendorf would not operate differently with the claimed dimension of the first distance indicated above and since the device is used for gripping an object (see paragraph 2 of Bendorf), the device would function appropriately having the claimed dimension. Further, it appears that applicant places no criticality on the range claimed, indicating simply that the dimensions of the first distance is about 43.5% of the second distance (see claim 2). In reference to claims 3, 4, 12 and 13, Bendorf lacks specifically disclosing that, the first distance is about 0.5 inches to about 1.0 inch; the first distance is about 0.637 inches. However, Bendorf does discloses that, “While particular embodiments have been shown and described, it will be apparent to those skilled in the art that changes and modifications may be made without departing from the broader aspects of the inventors' contribution.” (paragraph 20). In addition, Blumenthal et al. teach that it is old and well known in the art at the time the invention was made to provide a similar wrench (Figure 1) where the dimensions of the tool can be altered (see paragraph 63 disclosing that, "Further modifications and alternative embodiments of various aspects of the invention will be apparent to those skilled in the art in view of this description…Although only a few embodiments have been described in detail in this disclosure, many modifications are possible (e.g., variations in sizes, dimensions, structures, shapes and proportions of the various elements, values of parameters, mounting arrangements, use of materials, colors, orientations, etc.) without materially departing from the novel teachings and advantages of the subject matter described herein."). Thus, as such the dimensions of the tool (i.e. including the first and second distances) are considered as being a result effective variable in that changing the dimensions also changes the grasping force (see paragraph 5) and/or the torque increasing jaw design (see paragraph 2). Furthermore, Wu also teaches that it is old and well known in the art at the time the invention was made to provide a similar wrench (Figure 1) having a first distance (L2) located between a second jaw pivot (C2) and a link pivot (C3) and a second distance (see figure above) located between the second jaw pivot and a first jaw pivot (C1). The distances being selected “so as to be effort-saving” (see paragraphs 3, 27 and 31). Thus, in view of Blumenthal et al. and/or Wu, the first and second distances are considered as being a result effective variable because changing the first and second distances also changes the changes the grasping force (see paragraph 5 of Blumenthal et al.) and/or the torque increasing jaw design (see paragraph 2 of Blumenthal et al.) and/or the “effort-saving” (see paragraphs 3, 27 and 31 of Wu). Further, it appears that one of ordinary skill in the art would have had a reasonable expectation of success in modifying the Bendorf device to have; the first distance is about 0.5 inches to about 1.0 inch, the first distance is about 0.637 inches, as it involves only adjusting the dimensions of the first distance for the reasons previously discussed above. Therefore, it would have been obvious to one having ordinary skill in the art at the time of the invention to modify the device of Bendorf with the first distance is about 0.5 inches to about 1.0 inch or with the first distance is about 0.637 inches, as a matter of routine optimization, since it has been held that “where the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation." In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955). In the instant case, the device of Bendorf would not operate differently with the claimed dimension of the first distance indicated above and since the device is used for gripping an object (see paragraph 2 of Bendorf), the device would function appropriately having the claimed dimension. Further, it appears that applicant places no criticality on the range claimed, indicating simply that the dimensions of the first distance is about 0.5 inches or is about 0.637 inches, (see claims 3 and 4). In reference to claim 5, modified Bendorf obviously discloses that the first and second distances provide a clamping force between the first and second jaws that is about 25 times greater than an input force to push the first and second handles together to clamp the first and second jaws, because all of the structural limitations of the claims have been met and thus the first and second distances would obviously provide the same clamping force. In reference to claim 6, Bendorf discloses further comprising an adjustment screw mechanism (165) having a head (170) on a first end and a contact point (i.e. lower end of end of 175, in Figure 1) on a second end and threads (180) extending at least partially therebetween (paragraph 15), the adjustment screw mechanism being threadably inserted into the first handle for adjusting a gap between the first and second jaws (paragraph 15). In reference to claim 7, Bendorf discloses that the adjustment screw mechanism is adapted to be rotated clockwise to reduce the gap, and is adapted to be rotated counterclockwise to increase the gap (paragraph 15). In reference to claim 8, Bendorf discloses that the center link includes a face (i.e. formed as the face/portion of 185 that is engaged with the contact point/lower end of end of 175) and wherein a point of contact of the adjustment screw mechanism abuts the face during an adjustment operation in which the gap is adjusted (Figures 2 and 3). In reference to claim 9, Bendorf discloses that the release lever (187) includes an extension (i.e. 202) extending from an end (i.e. upper end in Figure 1) of the release lever (Figures 1 and 2), and wherein the center link (147) includes a protrusion (190, paragraph 16) protruding from the center link towards the second handle (Figures 1 and 2), wherein the abutment abuts the protrusion when the first and second jaws are in the locked state (Figure 2) and is spaced from the protrusion when the first and second jaws are in an open state (Figure 3 and paragraphs 16-18). In reference to claim 14, Bendorf discloses further comprising an adjustment screw mechanism (1650 having a head (170) on a first end and a contact point (i.e. lower end of end of 175, in Figure 1) on a second end and threads (180) extending at least partially therebetween (paragraph 15), the adjustment screw mechanism is threadably inserted into the first handle (paragraph 15), wherein a first line (see various examples the first line in the second figure below) extending through the second jaw pivot and the link pivot and a second line (see figures below) extending through the link pivot and the contact point are disposed apart by an angle of 171 to 172 degrees, because a plurality of first lines can be provided (see second figure below), and at least one of these first lines would obviously provide an angle of 171 to 172 degrees between the first line and the second line, depending on the particular angle that the first line extends between the second jaw pivot and the link pivot. Note, the examiner has included a dotted line in the first figure below showing an angle of 180 degrees for reference.

Bendorf lacks specifically disclosing that, the first distance is about 0.5 inches to about 1.0 inch. However, Bendorf does discloses that, “While particular embodiments have been shown and described, it will be apparent to those skilled in the art that changes and modifications may be made without departing from the broader aspects of the inventors' contribution.” (paragraph 20). In addition, Blumenthal et al. teach that it is old and well known in the art at the time the invention was made to provide a similar wrench (Figure 1) where the dimensions of the tool can be altered (see paragraph 63 disclosing that, "Further modifications and alternative embodiments of various aspects of the invention will be apparent to those skilled in the art in view of this description…Although only a few embodiments have been described in detail in this disclosure, many modifications are possible (e.g., variations in sizes, dimensions, structures, shapes and proportions of the various elements, values of parameters, mounting arrangements, use of materials, colors, orientations, etc.) without materially departing from the novel teachings and advantages of the subject matter described herein."). Thus, as such the dimensions of the tool (i.e. including the first and second distances) are considered as being a result effective variable in that changing the dimensions also changes the grasping force (see paragraph 5) and/or the torque increasing jaw design (see paragraph 2). Furthermore, Wu also teaches that it is old and well known in the art at the time the invention was made to provide a similar wrench (Figure 1) having a first distance (L2) located between a second jaw pivot (C2) and a link pivot (C3) and a second distance (see figure above) located between the second jaw pivot and a first jaw pivot (C1). The distances being selected “so as to be effort-saving” (see paragraphs 3, 27 and 31). Thus, in view of Blumenthal et al. and/or Wu, the first and second distances are considered as being a result effective variable because changing the first and second distances also changes the changes the grasping force (see paragraph 5 of Blumenthal et al.) and/or the torque increasing jaw design (see paragraph 2 of Blumenthal et al.) and/or the “effort-saving” (see paragraphs 3, 27 and 31 of Wu). Further, it appears that one of ordinary skill in the art would have had a reasonable expectation of success in modifying the Bendorf device to have; the first distance is about 0.5 inches to about 1.0 inch, as it involves only adjusting the dimensions of the first distance for the reasons previously discussed above.

In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955). In the instant case, the device of Bendorf would not operate differently with the claimed dimension of the first distance indicated above and since the device is used for gripping an object (see paragraph 2 of Bendorf), the device would function appropriately having the claimed dimension. Further, it appears that applicant places no criticality on the range claimed, indicating simply that the dimensions of the first distance is about 0.5 inches (see claims 3, 4 and 15). Response to Arguments Applicant’s arguments with respect to claims have been considered but are moot because the new ground of rejection does not rely on any reference as previously applied in the prior rejection of record for any teaching or matter as specifically challenged in the argument.
