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 .
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.
Claims 1-7,9,10,11,12,16,17,18,22,23,27 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by CN 109717592 (hereafter CN 592, cited by applicant).
With regard to claims 1,4,22 CN 592 discloses a hair care appliance (see fig. 1) for applying heat to a user's hair, the appliance comprising: an airflow passage (see inner passage) extending from an airflow inlet to an airflow outlet; an air mover 7 for moving airflow along the airflow passage from the airflow inlet to the airflow outlet; a heater arranged to heat air in the airflow passage, the heater comprising a heating element 13,14,15; and a thermal barrier 4 at least partly surrounding the heater (surrounds heating elements 13,14,15, see fig. 1), the thermal barrier comprising an inner wall 3 proximal to the heater, an outer wall 2 distal from the heater, and a sealed evacuated space defined between the inner and outer walls. See fig. 1 and the last paragraph of page 2 of the English translation.

With regard to claim 12, note that the mounting portion is an internal mounting portion (can be considered “internal” because it is attached to the inner wall, see above) and the thermal barrier further comprises an external mounting portion (see above annotated figure) directly opposite the internal mounting portion across the sealed evacuated space, the external mounting portion mounting the thermal barrier within a housing of the appliance.
With regard to claim 16, note that the inner and outer walls of the thermal barrier 4 are concentrically arranged. See figure 1.
With regard to claim 17, note that the outer wall of the thermal barrier 4 defines an external wall of the appliance. See figure 1.
With regard to claim 18, note that the outer wall 2 is thicker than the inner wall 3. See fig. 1.
Claims 22,27,28 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by JP H01214626A (hereafter referred to as JP 626).
With regard to claim 22, JP626 discloses a thermal barrier for an appliance, the thermal barrier comprising: concentrically arranged inner 3 and outer 8 tubular walls; a passage 2 defined by the inner tubular wall and extending through the thermal barrier between opposing openings thereof; a sealed evacuated space (see below) defined between the inner 3 and outer 8 tubular walls; and a mounting portion 4 for (capable of) mounting a heater across the passage, the mounting portion 4 in the form of a recess or protrusion formed in the inner tubular wall. See annotated figure below:

With regard to claim 27, note that the mounting portion is an internal mounting portion and the thermal barrier further comprises an external mounting portion directly opposite the internal mounting portion across the sealed evacuated space.
With regard to claim 28, note that when the internal mounting portion is a protrusion, the external mounting portion is a recess. See above annotated figure.
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 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.
Claim 23 is rejected under 35 U.S.C. 103 as being unpatentable over JP 626 in view of CN 592
With regard to claim 23, JP 626 does not disclose a bend along a length of the thermal barrier such that the opposing openings of the thermal barrier are angled with respect to each other, that passage extending along a curved path.
CN 592 discloses a device having a similar vacuum thermal barrier, the thermal barrier having a bend along a length such that opposing openings are angled with respect to each other, such that a passage therein extends along a curved path. See figure 1 and annotated figure above.
It would have been obvious to one skilled in the art to incorporate a bend along the length of the thermal barrier device of JP 626, as taught by CN 592, if one wished to incorporate the thermal barrier of JP 626 with a device that requires a non-linear path.
Claim 13 is rejected under 35 U.S.C. 103 as being unpatentable over CN 592 in view of JP 2002199923A (hereafter JP 923).
With regard to claim 13, CN 592 does not disclose when the internal mounting portion is a recess, the external mounting portion is a protrusion; and when the internal mounting portion is a protrusion, the external mounting portion is a recess (note: this claim only requires one of these scenarios for the claim to be met).
JP 923 discloses a device where an inner member is held within an outer member.

Note that the device uses an internal mounting portion comprising a recess (see above) and an external mounting portion comprising a protrusion 27.
It would have been obvious to one skilled in the art to utilize a recess and protrusion to mount the thermal barrier within the housing of the appliance of CN 592, in view of the teaching of JP 923 that such an arrangement can be used to mount an inner tubular member within an outer tubular member.
Claim 19 is rejected under 35 U.S.C. 103 as being unpatentable over CN 592 in view of Conrad et al 20210307473.
With regard to claim 19, CN 592 does not disclose wherein an inner surface of the inner wall comprises an electrically insulative coating.
Conrad et al discloses a hair dryer which incorporates a coating (layer) of electrically insulative material 418. See paragraph 934 and fig. 97.
It would have been obvious to one skilled in the art to include an electrically insulative coating on the inner wall of the device of CN 592, in view of the teaching of Conrad et al that it is known to provide an electrically insulative coating on a wall facing a heating element in a hair dryer.
