Office Action

§101 §102 §103
DETAILED ACTION Notice of 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 . Claims 1-20 are pending and are rejected. Information Disclosure Statement The information disclosure statements (IDSs) filled on 11/21/2023 is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statements are being considered by the examiner. Drawings Drawings filled on 11/21/2023 are acceptable for the examination purpose. Claim Rejections - 35 USC § 101 35 U.S.C. 101 reads as follows: Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title. Claim 8: Claims 8 is rejected under 35 U.S.C. 101 because the claimed invention is directed to non-statutory subject matter. The claim does not fall within at least one of the four categories of patent eligible subject matter, because the subject matter of claim are directed to transitory form of computer-readable storage medium. Non-limiting examples of claims that are not directed to any of the statutory categories include: Transitory forms of signal transmission (often referred to as "signals per se"), such as a propagating electrical or electromagnetic signal or carrier wave; Claim recites “A computer program product residing on a computer readable storage medium” such that the subject matter of claim are directed to transitory form of computer-readable storage medium. A transitory, propagating signal does not fall within any statutory category. Mentor Graphics Corp. v. EVE-USA, Inc., 851 F.3d 1275, 1294, 112 USPQ2d 1120, 1133 (Fed. Cir. 2017); Nuijten, 500 F.3d at 1356-1357, 84 USPQ2d at 1501-03. The specification ¶63 states that computer program product residing on the computer readable storage medium and the computer readable medium may be a computer readable signal medium or a computer readable storage medium,… a computer-readable storage medium may be, for example, but is not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, device, or any suitable combination of the foregoing. Combinations of any of the above should also be included within the scope of computer-readable storage media. Therefore, the computer readable storage medium is not patentable since the limitation does not fall under one of the statutory categories such that process, machine, manufacture or composition of matter. Also, computer-readable storage media can be construed to encompass an unpatentable medium such as data and programs electrically, magnetically, optically, mechanically or by chemical action. Therefore, the claim is not a statutory subject matter and is rejected under 35 U.S. C. § 101 as not being tangible. Therefore, claim 8 does not fall within at least one of the four categories of patent eligible subject matter. For the same reasons as described above for claim 8, dependent claims 9-14 also do not fall within at least one of the four categories of patent eligible subject matter. Claim Objections Claims 6, 13 and 19: Claims 6, 13 and 19 are objected to because of the following informalities: These claims recite the abbreviation PVA but doesn’t recite the full term. The specification ¶25 describes it as poly vinyl alcohol, and thus for the examination purpose, this term PVA is construed as poly vinyl alcohol for all these claims. Appropriate correction is required. Claims 6, 13 and 19: Claims 6, 13 and 19 are objected to because of the following informalities: These claims simply states, synthesizing PVA solution by mixing water and adding mesoporous C, and NiAg and then removing supernatant from the solution that are mere mixing and combining chemicals and removing liquid after chemical reaction and doesn’t further recite what is done with this PVA solution. Therefore, it isn’t clear what is done with this solution. Applicant’s specification ¶5 describes, coating the TCPFL with the PVA solution; therefore, for the examination purpose, it is construed that, the claims include additional limitation of coating the TCPFL with the PVA solution. Appropriate correction is required. Claim Rejections - 35 USC § 102 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. The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.

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. 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 filling 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 for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: Determining the scope and contents of the prior art. Ascertaining the differences between the prior art and the claims at issue. Resolving the level of ordinary skill in the pertinent art. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claim(s) 5 and 8-12 is/are rejected under 35 U.S.C. 103 as being unpatentable over Li and further in view of Browne et al. (US20050218710A1) [hereinafter BROWNE]. Regarding claim 5: Li discloses, The method of claim 1, and Li further discloses, the vehicular component [¶163: Both torsional and tensile actuation of hybrid twist-spun yarns and twist inserted fibers can be deployed for actuating smart surfaces on local and larger scales. For instance, tensile actuation can reversibly retract…thereby changing surface roughness.

Examiner notes that, Li teaches the use of TCPFL actuators for various components of vehicles including various surfaces (could be seat)], but doesn’t explicitly disclose, and BROWNE discloses, wherein the vehicular component includes a seat. [¶6: A seat assembly includes a seat fabric, wherein at least a portion of the seat fabric comprises a yarn comprising a shape memory polymer adapted to undergo a change in a modulus of elasticity at a thermal transition temperature;… ¶21: The shape memory polymer may be heated by any suitable means. For example, for elevated temperatures, heat may be supplied using hot gas (e.g., air), steam, hot liquid, or electrical current]. Therefore, it would have been obvious to one of ordinary skill in the art before the filling date of the claimed invention to have combined the technique of using the TCPFL actuators for various components of vehicles including various surfaces (could be seat) by taking advantage of the TCPFL extension and retraction properties in response to thermal changes and use these TCPFL actuators for the surface of a vehicle component such as a seat in order to providing a vehicle seat that is less expensive, quieter, more lightweight, and/or less interfering than existing seat assemblies with techniques that allows to avoid discomfort or sore spots by adjusting the shape of the seat assembly to the shape of the seat user taught by BROWNE with the method taught by Li as discussed above in order to have reasonable expectation of success such as to providing a vehicle seat that is less expensive, quieter, more lightweight, and/or less interfering than existing seat assemblies with techniques that allows to avoid discomfort or sore spots by adjusting the shape of the seat assembly to the shape of the seat user [BROWNE, ¶25: avoid discomfort or sore spots, the shape of the seat assembly 20 can be adjusted to the shape of the seat user….¶36: the seat assembly can be less expensive, quieter, more lightweight, and/or less interfering than existing seat assemblies.].

The controller 14 is operable to selectively apply the activation signal (i.e., heat) to at least a portion of the SMP to effect the change in the modulus of elasticity, which enables the seat fabric 10 to undergo a change in its compliance and/or shape. In one embodiment, the change in compliance and/or shape is reversible. Examiner notes that, BROWNE discloses, controller that includes cpu and storage medium, memory etc.]. Therefore, it would have been obvious to one of ordinary skill in the art before the filling date of the claimed invention to have combined the computer program product residing on a computer readable storage medium having a plurality of instructions stored thereon which, when executed across one or more processors, causes at least a portion of the one or more processors to perform operations for using a twisted and coiled polymer fishing line in order to providing a vehicle seat that is less expensive, quieter, more lightweight, and/or less interfering than existing seat assemblies with techniques that allows to avoid discomfort or sore spots by adjusting the shape of the seat assembly to the shape of the seat user taught by BROWNE with the system taught by Li as discussed above in order to have reasonable expectation of success such as to providing a vehicle seat that is less expensive, quieter, more lightweight, and/or less interfering than existing seat assemblies with techniques that allows to avoid discomfort or sore spots by adjusting the shape of the seat assembly to the shape of the seat user [BROWNE, ¶25: avoid discomfort or sore spots, the shape of the seat assembly 20 can be adjusted to the shape of the seat user….¶36: the seat assembly can be less expensive, quieter, more lightweight, and/or less interfering than existing seat assemblies.].

Claim(s) 6 and 19 is/are rejected under 35 U.S.C. 103 as being unpatentable over Li and further in view of Custer et al. (US20100189988A1) [hereinafter Custer]. Regarding claim 6: Li discloses, The method of claim 1, but doesn’t explicitly disclose, and Custer discloses, further comprising synthesizing a PVA solution, wherein synthesizing the PVA solution includes: dissolving an amount of PVA in water to create a solution; adding mesoporous C, and NiAg metal mesh powder to the solution; and removing supernatant from the solution.

Metal-coated fillers may also be used, for example nickel coated carbon particles and silver coated copper particles. Examiner notes the claim objections as set forth in this office action, and it is construed that the mixture claimed is used for coating. Examiner notes that, Custer teaches of 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)].

Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure is listed in the PTO-892 Notice of Reference Cited document. 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. Sluis et al. (US20240336129A1) - Twisted coiled actuator kinematic system for automotive aero devices: ¶17: soft actuator preferably twisted coiled polymer (TCP) units which are arranged in a kinematic mechanism system that allows the TCP to act as a load generation unit for pre-loading a spring to engage in a trigger-latch mechanism also utilizing a TCP to release the trigger-latch element for each cycle of the overall system. 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.
