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, 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 2, 6-7, 14-17, and 19-20 are rejected under 35 U.S.C. 103 as being unpatentable over US 20180361200 A1 (Walker). Regarding Claim 2, Walker discloses the invention as substantially claimed, see above. Walker does not disclose wherein the arm member is a telescoping arm member operable to extend along a longitudinal axis thereof, the arm member further comprising a tube coupling member operable to secure the arm member at a desired length. Walker in a second embodiment teaches an analogous arm exercise device comprising: an interfacing member (pedal 5605) attached toward a second end (distal end) of an arm member (crank 5602) and configured to interface with the body of a user (pedal 5605 is configured to be engaged with a user’s foot); wherein the arm member is a telescoping arm member operable to extend along a longitudinal axis thereof (“Pedal extension 5603, optionally telescopes into and out of crank 5602” Paragraph 234), the arm member further comprising a tube (pedal extension 5603) coupling member operable to secure the arm member at a desired length (lockable by pedal extension lock 5604). PNG media_image5.png 307 459 media_image5.png Greyscale It would have been obvious for one skilled in the art at the time of filing to modify the arm to be telescoping with a tube securable at a desired length as taught by Walker in the second embodiment in order to provide adjustability for user’s of different sizes. Regarding Claim 6, Walker further discloses the exercise device of claim 1 wherein: the vertical extension member comprises: one track channel extending vertically along the vertical extension member (channel between the posts 36); and a plurality of apertures (see Figures 1-4 wherein the posts 36 have a plurality of holes along their lengths); and the vertical sliding member comprises: one attaching member (housing 51) configured to slidably attach the vertical sliding member to the vertical extension members such that the vertical sliding member may translate along the one track channel (housing 51 is configured to slide along post 36 and within the channel to selectable locations along the post 36); PNG media_image6.png 397 383 media_image6.png Greyscale Figure 8 a position retaining member (cam release lock 34) configured to be selectively retain the vertical sliding member at a vertical position along the vertical extension member (cam lock 34 is configured to hold housing 51 at a selectable height along post 36).

PNG media_image5.png 307 459 media_image5.png Greyscale It would have been obvious for one skilled in the art at the time of filing to modify the arm to be telescoping with a tube securable at a desired length as taught by Walker in the second embodiment in order to provide adjustability for users of different sizes. Regarding Claim 15, Walker as modified further discloses the exercise device of claim 14 wherein the angle selection structure comprises: an aperture (the plate that pin 46 passes through has an aperture such that the handle is on one side of the plate and the pin passes through the opposite side into the pin plate 48) configured to align with the recesses of the plurality of recesses (see Figure 2 wherein the apertures align such that the pin 46 passes through both apertures when aligned); and an angle selection structure retaining member (pin 46) configured to pass through the aperture and into the recesses of the plurality of recesses (pin 46 is configured to pass through the aperture and respective hole 50 when the hole and apertures are aligned and pin passes therethrough). Regarding Claim 16, Walker further discloses the exercise device of claim 14 wherein: the vertical extension member comprises: one track channel extending vertically along the vertical extension member (channel between the posts 36); and a plurality of apertures (see Figures 1-4 wherein the posts 36 have a plurality of holes along their lengths); and the vertical sliding member comprises: one attaching member (housing 51) configured to slidably attach the vertical sliding member to the vertical extension members such that the vertical sliding member may translate along the one track channel (housing 51 is configured to slide along post 36 and within the channel to selectable locations along the post 36); PNG media_image6.png 397 383 media_image6.png Greyscale Figure 8 a position retaining member (cam release lock 34) configured to be selectively retain the vertical sliding member at a vertical position along the vertical extension member (cam lock 34 is configured to hold housing 51 at a selectable height along post 36). Walker does not disclose a position retaining member configured to be selectively positionable within the plurality of apertures to selectively retain the vertical sliding member at a vertical position along the vertical extension member. Walker in a second embodiment teaches an analogous exercise device comprising: A vertical extension member (extension arm 4905) comprises: a plurality of apertures (selector holes 4904); and the vertical sliding member comprises: one or more attaching members (extension arm sleeve 4901) configured to slidably attach the vertical sliding member to the vertical extension members (see Figure 49); PNG media_image7.png 341 233 media_image7.png Greyscale Figure 49 and a position retaining member (extension lock 4902) configured to be selectively positionable within the plurality of apertures to selectively retain the vertical sliding member at a vertical position along the vertical extension member (extension lock 4902 is configured to selectively engage holes 4904 to select the height of sleeve 2901 relative to post 4905). It would have been obvious for one skilled in the art at the time of filing to modify the position retaining member to be an extension lock engagable with the apertures along the vertical member, as taught by Walker in the second embodiment, in order to provide physical locking and prevent slippage of the locking mechanism. Regarding Claim 17, Walker discloses the invention as substantially claimed, see above. Walker does not disclose a housing; and at least one resistance member positioned at least partially within the housing and configured to resist rotation about the second axis in at least one direction. Walker in a second different embodiment teaches an analogous exercise device comprising: a housing (resistance apparatus 1200 cover, Figure 16); and at least one resistance member (weight stack shown in Figure 16 within the apparatus 1200 cover) positioned at least partially within the housing (see Figure 16) and configured to resist rotation about the second axis in at least one direction (said weight stack is configured to resist motion). PNG media_image8.png 534 493 media_image8.png Greyscale Figure 16 It would have been obvious for one skilled in the art at the time of filing to modify the frame to include a housing partially surrounding the resistance member as taught by Walker in the second embodiment in order to prevent unintended interaction with the weight stack while in use. Regarding Claim 19, Walker further discloses the exercise device of claim 14 wherein the interfacing member comprises: an attachment section (hole 110 with pin 107) configured to attach to the arm member (pin 107 passes through hole 110 and locks the attachment 100 to the arm 32); a body section (attachment 100 with holes 104); PNG media_image4.png 489 476 media_image4.png Greyscale Figure 14 and one or more interfacing devices (finger handle 1100, Figure 14; “preferable free spinning finger cradle attachment 1100 is attached to elbow cradle attachment 100” Paragraph 185) carried by the body section and configured to interface with the body of the user (finger handle 1100 is configured to interface with the user’s fingers).

Allowable Subject Matter Claims 8-9, 12, 18 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. The following is a statement of reasons for the indication of allowable subject matter: Regarding claims 8 and 18 the prior art of record US 20180361200 A1 (Walker) fails to teach or render obvious the exercise device in combination with all of the elements and structural and functional relationships as claimed and further including: rotation of the arm member about the second axis causes the housing to rotate about the second axis The prior art of record teaches the housing as attached to the frame covering the weight stack, which are not considered equivalent to applicant’s invention as it does not move. It would not have been obvious for one skilled in the art at the time of filing to modify the housing to be attached to the arm such that it rotates as it would not be covering the resistance mechanism, nor would it be obvious to modify the housing to rotated with the arm without breaking the functionality of the device. Regarding claim 12 the prior art of record US 20180361200 A1 (Walker) fails to teach or render obvious the exercise device in combination with all of the elements and structural and functional relationships as claimed and further including: wherein the vertical extension member further comprises an attachment structure configured to rotatably attach the vertical extension member to the base such that the vertical extension member is rotatable about a third axis relative to the base. The prior art of record teaches vertical posts 36 bolted down into a framelike structure intended to stay stationary and prevent unintended motion of the weight stack and cables, which is not equivalent to applicant’s invention. It would not have been obvious for one skilled in the art at the time of filing to modify the vertical posts to rotate relative to the base without breaking the functionality of the device and without improper hindsight.
