Office Action

§102 §103 §112
DETAILED ACTION This is the first Office action on the merits based on the 18/682,503 application filed on 02/09/2024 and applicant’s preliminary amendments filed 02/09/2024. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . The effective filing date of the present application is 08/12/2021. In applicant’s preliminary amendments filed 02/09/2024, claim 10 was amended. Claims 1-21, as filed on 02/09/2024, are currently pending and considered below. Priority Receipt is acknowledged of certified copies of papers submitted under 35 U.S.C. 119(a)-(d), which papers have been placed of record in the file. Information Disclosure Statement The information disclosure statements (IDS) submitted on 02/09/2024 and 01/07/2025 were in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statements are being considered by the examiner. Drawings The drawings are objected to because poor quality, line weight, and overall drawing sizes used in the illustrations of Figures 1-13 render details in the drawings unclear. No new matter should be entered. Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Specification The abstract of the disclosure is objected to because of undue length. See below. A corrected abstract of the disclosure is required and must be presented on a separate sheet, apart from any other text. See MPEP § 608.01(b). Applicant is reminded of the proper language and format for an abstract of the disclosure. The abstract should be in narrative form and generally limited to a single paragraph on a separate sheet within the range of 50 to 150 words in length. The abstract should describe the disclosure sufficiently to assist readers in deciding whether there is a need for consulting the full patent text for details. The language should be clear and concise and should not repeat information given in the title. It should avoid using phrases which can be implied, such as, “The disclosure concerns,” “The disclosure defined by this invention,” “The disclosure describes,” etc. In addition, the form and legal phraseology often used in patent claims, such as “means” and “said,” should be avoided. Claim Objections Claims 1, 10, 11, 16, and 21 are objected to because of the following informalities: In claim 1, line 2, “a rotatable power output member; and” should be --- a power output member being rotatable; and ---.

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 4, 8, 12, 13, and 16 are rejected under 35 U.S.C. 103 as being unpatentable over Sherin (US 2018/0214731) in view of Rea (US 9,320,936). Regarding claim 4, Sherin discloses the invention as substantially claimed, see above, but fails to disclose: wherein clamping teeth are formed on an inner peripheral side of the transmission toothed disc, clamping grooves are correspondingly formed on an outer peripheral side of the rotating shaft, and the clamping teeth are correspondingly matched with the clamping grooves so that the transmission toothed disc and the rotating shaft can keep rotating synchronously. Rea teaches an analogous exercise device (Figures 1-4) wherein clamping teeth (the serrated splines 63; Figure 8; column 6, line 16, through column 7, line 17) are formed on an inner peripheral side (the inwardly facing surface of the concentric through-hole 62; Figure 8; column 6, lines 16-46) of a transmission disc (the resistance pack 48; Figure 8; column 6, line 16, through column 7, line 17), clamping grooves (the engagement pattern 42 which can be a mating engagement pattern to combine with the serrated splines 63; Figures 1, 2, 4, and 5; column 6, line 36, through column 7, line 17) are correspondingly formed on an outer peripheral side of a rotating shaft (the outer peripheral surface of the rod portion 40 of the key(s) 30; Figures 1-4; column 6, line 36, through column 7, line 17), and the clamping teeth are correspondingly matched with the clamping grooves so that the transmission disc and the rotating shaft can keep rotating synchronously (“More particularly, as will be seen from FIG. 5, a first key 30A according to the invention could have a spool spline 45A for locking in relation to the respective spool 16 or 22 and then a spline pattern 42A with just a single spline portion for locking only the first resistance pack 48 to rotate with the key 30A and the spool 16 or 22.”; column 6, lines 61-66; Figures 1-4 and 8). It would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to modify Sherin’s invention to include clamping teeth formed on an inner peripheral side of the transmission toothed disc and clamping grooves correspondingly formed on an outer peripheral side of the rotating shaft, as taught by Rea, in order to ensure that the transmission toothed disc is locked to rotate with the rotating shaft (Rea: Figures 1-4 and 8; column 6, line 16, through column 7, line 17). Regarding claim 8, Sherin discloses the invention as substantially claimed, see above, but fails to disclose: wherein clamping teeth are formed on an inner peripheral side of the independent output wheel, clamping grooves are correspondingly formed on an outer peripheral side of the rotating shaft, and the clamping teeth are correspondingly matched with the clamping grooves so that the independent output wheel and the rotating shaft can keep rotating synchronously. Rea teaches an analogous exercise device (Figures 1-4) wherein clamping teeth (the serrated splines 63; Figure 8; column 6, line 16, through column 7, line 17) are formed on an inner peripheral side (the inwardly facing surface of the concentric through-hole 62; Figure 8; column 6, lines 16-46) of an independent output wheel (the resistance pack 48; Figure 8; column 6, line 16, through column 7, line 17), clamping grooves (the engagement pattern 42 which can be a mating engagement pattern to combine with the serrated splines 63; Figures 1, 2, 4, and 5; column 6, line 36, through column 7, line 17) are correspondingly formed on an outer peripheral side of a rotating shaft (the outer peripheral surface of the rod portion 40 of the key(s) 30; Figures 1-4; column 6, line 36, through column 7, line 17), and the clamping teeth are correspondingly matched with the clamping grooves so that the independent output wheel and the rotating shaft can keep rotating synchronously (“More particularly, as will be seen from FIG. 5, a first key 30A according to the invention could have a spool spline 45A for locking in relation to the respective spool 16 or 22 and then a spline pattern 42A with just a single spline portion for locking only the first resistance pack 48 to rotate with the key 30A and the spool 16 or 22.”; column 6, lines 61-66; Figures 1-4 and 8). It would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to modify Sherin’s invention to include clamping teeth formed on an inner peripheral side of the independent output wheel and clamping grooves correspondingly formed on an outer peripheral side of the rotating shaft, as taught by Rea, in order to ensure that the independent output wheel is locked to rotate with the rotating shaft (Rea: Figures 1-4 and 8; column 6, line 16, through column 7, line 17). Regarding claim 12, Sherin discloses the invention as substantially claimed, see above, and further discloses wherein the power output member of the independent constant torque force generator is an independent output wheel (the second storage drum 114A; Figures 1-3 and 7). However, Sherin fails to disclose: clamping teeth are formed on an inner peripheral side of the independent output wheel, clamping grooves are correspondingly formed on an outer peripheral side of the rotating shaft, and the clamping teeth are correspondingly matched with the clamping grooves so that the independent output wheel and the rotating shaft can keep rotating synchronously. Rea teaches an analogous exercise device (Figures 1-4) wherein clamping teeth (the serrated splines 63; Figure 8; column 6, line 16, through column 7, line 17) are formed on an inner peripheral side (the inwardly facing surface of the concentric through-hole 62; Figure 8; column 6, lines 16-46) of an independent output wheel (the resistance pack 48; Figure 8; column 6, line 16, through column 7, line 17), clamping grooves (the engagement pattern 42 which can be a mating engagement pattern to combine with the serrated splines 63; Figures 1, 2, 4, and 5; column 6, line 36, through column 7, line 17) are correspondingly formed on an outer peripheral side of a rotating shaft (the outer peripheral surface of the rod portion 40 of the key(s) 30; Figures 1-4; column 6, line 36, through column 7, line 17), and the clamping teeth are correspondingly matched with the clamping grooves so that the independent output wheel and the rotating shaft can keep rotating synchronously (“More particularly, as will be seen from FIG. 5, a first key 30A according to the invention could have a spool spline 45A for locking in relation to the respective spool 16 or 22 and then a spline pattern 42A with just a single spline portion for locking only the first resistance pack 48 to rotate with the key 30A and the spool 16 or 22.”; column 6, lines 61-66; Figures 1-4 and 8). It would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to modify Sherin’s invention to include clamping teeth formed on an inner peripheral side of the independent output wheel and clamping grooves correspondingly formed on an outer peripheral side of the rotating shaft, as taught by Rea, in order to ensure that the independent output wheel is locked to rotate with the rotating shaft (Rea: Figures 1-4 and 8; column 6, line 16, through column 7, line 17). Regarding claim 13, Sherin in view of Rea teaches the invention as substantially claimed, see above, and further teaches wherein the clamping teeth are provided on an inner peripheral side of the reel, and are correspondingly matched with the clamping grooves of the rotating shaft, so that the reel can drive the rotating shaft to rotate synchronously (“More particularly, as will be seen from FIG. 5, a first key 30A according to the invention could have a spool spline 45A for locking in relation to the respective spool 16 or 22 and then a spline pattern 42A with just a single spline portion for locking only the first resistance pack 48 to rotate with the key 30A and the spool 16 or 22.”; column 6, lines 61-66; Figures 1-4 and 8). Regarding claim 16, Sherin discloses the invention as substantially claimed, see above, but fails to disclose: wherein clamping teeth are formed on an inner peripheral side of the transmission toothed disc, clamping grooves are correspondingly formed on an outer peripheral side of the rotating shaft, and the clamping teeth are correspondingly matched with the clamping grooves so that the transmission toothed disc and the rotating shaft can keep rotating synchronously. Rea teaches an analogous exercise device (Figures 1-4) wherein clamping teeth (the serrated splines 63; Figure 8; column 6, line 16, through column 7, line 17) are formed on an inner peripheral side (the inwardly facing surface of the concentric through-hole 62; Figure 8; column 6, lines 16-46) of a transmission disc (the resistance pack 48; Figure 8; column 6, line 16, through column 7, line 17), clamping grooves (the engagement pattern 42 which can be a mating engagement pattern to combine with the serrated splines 63; Figures 1, 2, 4, and 5; column 6, line 36, through column 7, line 17) are correspondingly formed on an outer peripheral side of a rotating shaft (the outer peripheral surface of the rod portion 40 of the key(s) 30; Figures 1-4; column 6, line 36, through column 7, line 17), and the clamping teeth are correspondingly matched with the clamping grooves so that the transmission disc and the rotating shaft can keep rotating synchronously (“More particularly, as will be seen from FIG. 5, a first key 30A according to the invention could have a spool spline 45A for locking in relation to the respective spool 16 or 22 and then a spline pattern 42A with just a single spline portion for locking only the first resistance pack 48 to rotate with the key 30A and the spool 16 or 22.”; column 6, lines 61-66; Figures 1-4 and 8). It would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to modify Sherin’s invention to include clamping teeth formed on an inner peripheral side of the transmission toothed disc and clamping grooves correspondingly formed on an outer peripheral side of the rotating shaft, as taught by Rea, in order to ensure that the transmission toothed disc is locked to rotate with the rotating shaft (Rea: Figures 1-4 and 8; column 6, line 16, through column 7, line 17). Claim 19 is rejected under 35 U.S.C. 103 as being unpatentable over Sherin (US 2018/0214731) in view of Herring (WO 2021034671 A1). Regarding claim 19, Sherin discloses the invention as substantially claimed, see above, and further discloses wherein the rotating shaft is fixed to a bracket (the housing 104; Figure 1). However, Sherin is silent as to: a suction cup is provided on the bracket. Herring teaches an analogous exercise device (the cable training device 100; Figures 1A-3B) wherein a suction cup is provided on a bracket (“In select embodiments, modular mount 130 may be a commercial-grade suction cup, which can be appropriate for relatively smooth surfaces. In embodiments in which the modular mount 130 is a suction cup mount, the modular mount 130 may have a 6” diameter, a holding capacity of at least 210 pounds, a manual pump to remove pressure between the mounting surface and the suction cup, and/or a colored indication band to signal whether additional suction is needed to properly secure the suction cup to the mounting surface.”; page 7, lines 2-8; Figures 1A and 1B). It would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to modify the bracket of Sherin’s invention to include a suction cup, as taught by Herring, in order to facilitate attachment of the real-time constant-force tension device to relatively smooth surfaces while also providing a holding capacity of the real-time constant-force tension device of at least 210 pounds (Herring: page 7, lines 2-8). Allowable Subject Matter Claims 5, 6, 17, 18, and 21 would be allowable if rewritten to overcome the rejections under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action and to include 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: The prior art of record (Sherin (US 2018/0214731); Rea (US 9,320,936); Herring (WO 2021034671 A1); Wang (CN 212593705 U); Hoecht (US 2005/0181915); Colosky, Jr. (US 2002/0025891)), alone or in combination, fails to teach or render obvious a constant torque force generator in combination with all of the elements and structural and functional relationships as claimed and further including: an insert piece that can be cut in radially is arranged on a radial outer side of each transmission toothed disc, and one end of the insert piece facing the transmission toothed disc is an insert blade with a slope (claim 5).
