Applicant’s arguments, see pages 9-10 of applicant’s remarks, filed 12/22/201, with respect to rejections under 35 U.S.C. § 102 have been fully considered and are persuasive. The 35 U.S.C. § 102 rejections of claims 1-4 and 15-18 has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made under 35 U.S.C. § 103 in view of the references as presented in the current office action.
Applicant responds
(a) Rejections under 35 U.S.C. § 102
Because of the foregoing discussion, inter alia, Applicant respectfully contends that Li at least fails to anticipate the claimed features under 35 U.S.C. § 102 because of the absence from Li of Applicant's claimed "receiving a TCPFL actuator, wherein the TCPm actuator is fabricated from a plurality of TCPm muscles coated with a synthesized polyvinyl alcohol (PVA) solution" similarly recited in independent claims 1, 8, and 15. Accordingly, Applicant respectfully requests that the rejection be withdrawn.
(Page: 11)
With respect to (a) above, Examiner appreciates the interpretative description given by Applicant in response.
Applicant’s amendments to claims 1, 8 and 15 have overcome the 35 U.S.C. § 102 rejections of claims 1-4 and 15-18; however, all claims 1-20 are rejected under 35 U.S.C. § 103 in view of the references as presented in the current office action in response to the amendments.
Applicant's arguments filed 05/06/2026 have been fully considered but they are not persuasive.
Applicant responds
(b) Rejections under 35 U.S.C. § 102:
Applicant respectfully submits that Li at least fails to anticipate Applicant's claimed "receiving a TCPFL actuator, wherein the TCPFL actuator is fabricated from a plurality of TCPFL muscles."
As seen above, Li appears to describe artificial muscles fabricated from twisted polymer fibers. See Li f[0027]. Li further appears to describe suitable polymer materials for such polymer fiber muscles, including fibers commonly used for fishing lines. See Li f[0134]. However, these disclosures describe the structure and materials of individual artificial muscles, not an actuator fabricated from a plurality of TCPFL muscles as claimed.
Li does not disclose that such a device includes a plurality of artificial muscles forming a single actuator, nor does Li describe an actuator fabricated from multiple TCPFL muscles. Accordingly, Li fails to disclose the claimed "receiving a TCPFL actuator, wherein the TCPFL actuator is fabricated from a plurality of TCPFL muscles."
(Pages: 7-9)
With respect to (b) above, Examiner appreciates the interpretative description given by Applicant in response.
The limitation, receiving a TCPFL actuator, wherein the TCPFL actuator is fabricated from a plurality of TCPFL muscles is broad.
In broadest reasonable interpretation, receiving a TCPFL actuator means receiving the TCPFL actuator from any place in any manner for any use.
In broadest reasonable interpretation, TCPFL actuator is fabricated from a plurality of TCPFL muscles describes plurality of TCPFL muscles with actuation ability, because claim doesn’t provide any specific detail about how exactly this TCPFL actuator is fabricated from the TCPFL muscles and what the exact structure of this TCPFL actuator.
As described above, combination of the Li and Custer disclose all the elements of claims 1 and 15, and combination of the Li, Custer and BROWNE disclose all the elements of claim 8.
Applicant’s arguments are fully considered, but for the above described reasons, they are not persuasive; therefore, claims 1-20 are rejected under 35 USC §103 in view of the references as set forth in this office action.
(c) Rejections under 35 U.S.C. § 103:
Additionally, regarding claim 6
However, the cited portions of Custer do not disclose, either individually or collectively, the claimed synthesis of a PVA solution or the specific process steps recited in claim 6. Custer discloses that a fibrous material "may be coated or impregnated with curative"
Custer neither discloses mesoporous carbon nor any NiAg alloy or metal mesh powder, and instead lists these materials as independent alternatives rather than as a specific combined composition.
yet none of the cited portions of Custer disclose the formation of a solution from which a supernatant would be removed, nor any precipitation or separation step.
Custer does not disclose synthesizing a PVA solution using the recited steps, and the rejection is based on an improper reconstruction of the claimed process using Applicant's disclosure as a template. Accordingly, Custer fails to teach the limitations of claim 6, and the rejection should be withdrawn.
(Page: 10)
With respect to (c) above, Examiner appreciates the interpretative description given by Applicant in response.
The claimed limitation is broad, and in broadest reasonable interpretation describes creating a PVA solution by mixing mesoporous C, and NiAg metal mesh powder with (polyvinyl alcohol) PVA and water and then removing supernatant. There are no specific steps with detailed chemical reactions other than just mixing these elements and then removing supernatant.
Custer describes mixture of fillers Ni Ag and conducting grades of carbons and PVA solution. As described in the current office action, Examiner noted that, Custer teaches, creating a mixture (combination) and combining it with the element (fibrous material). Examiner further notes that one of the ordinary skilled in the art will understand that, the supernatant that is liquid lying above solid residue after chemical combination/reaction can be removed and disposed off before obtaining the solid residue after precipitation (coating/combining).
Applicant’s arguments are fully considered, but for the above described reasons, they are not persuasive; therefore, claims 1-20 are rejected under 35 USC §103 in view of the references as set forth in this office action.
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 (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.

Ridley et al. (US20180291535A1) - Coiled actuator system and method:
¶24: coiled actuators (“artificial muscles”) can be produced through a twist insertion process. For example, a fiber can be twisted to the point of coiling. In another example, a fiber can be twisted nearly to the point of coiling and then wrapped around a mandrel or fiber or yarn core. Although various examples discussed herein refer to a fiber, it should be clear that various embodiments can comprise any suitable elongated element, including a fiber, filament, ribbon, yarn, line, or the like. Additionally, as used herein, a ‘fiber’ can encompass any such elongated elements, including a yarn comprising one or more fibers or other elements, a fiber comprising a single elongated element, or the like.

Hulway (US20150197173A1) - Electro-active polymer actuators for vehicle seating applications:
¶3: vehicle seat includes a seat base and a seat back, each having a spring structure and a cushion. Planar electro-active polymer actuators each have a first side coupled with the spring structure and an opposing second side positioned distal from the spring structure and in direct communication with the cushion. Each of the actuators is disposed in a first state. A control for the actuators is in communication with the actuators and is configured to deliver a predetermined electrical input to one or more of the actuators. The predetermined electrical input is configured to deform at least one of the actuators to a second state. The deformation of each actuator from the first state to the second state directly operates the cushion between a plurality of comfort positions.
