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 .
Response to Amendment
The Amendment filed on 4/22/2026 has been entered. Claim 2 was canceled. Claims 1 and 3-15 remain pending in the application. Applicant’s amendments to the Claims have overcome each and every 112(b) rejections.
Response to Arguments
Applicant's arguments filed on 4/22/2026 have been fully considered but they are not persuasive.
Applicant asserts that both Yoneda (U.S. Pre-Grant Publication No. 2015/0340182) and Deenen (U.S. Pre-Grant Publication No. 2013/0168379) fails to teach the claimed limitation “wherein the conductive element is spaced from the substrate such that heat transfer between the substrate and the conductive element occurs through conduction at the ends of the conductive elements or by convection through the medium surrounding the conductive element.”
The Examiner respectfully disagrees. The broadest reasonable interpretation of the abovementioned claim limitation is:
there is a space between the substrate and the conductive element; AND
there is thermal conduction between the substrate and ends of the conductive element; OR
there is thermal convection between the substrate and the conductive element via fluid surrounding the conductive element.
For Yoneda, it is clearly shown in figure 5 that Yoneda’s conductive element 108 is spaced by electrodes 104 and 106, and because the electrodes 104 and 106 are both in contact with the ends of the conductive element 108 and substrate 102, the conductive element 108 is in thermal conduction to substrate 102 at its ends via electrodes 104 and 106. Furthermore, the surrounding air within the enclosure shown in figure 5 would attribute thermal convection to the conductive element 108.

For Deenen, thermal fuse 105 (conductive element) is in electrical connection with resistive track 6, which is directly on plate 20 (substrate) (paragraph [0075]). Applicant’s Remark’s page 8 admits this is true. A thermal fuse is inherently a conductor that extends between two ends wherein the conductor melts when it causes excessive heat in the electrical circuitry. Therefore, inherently, the two ends of Deenen’s thermal fuse 105 is also in heat transfer via conduction with the substrate 20. It should be noted that Deenen’s thermal fuse 105 is spaced from substrate 20 at least by insulator 107 shown in figure 6a. Furthermore, Deenen teaches the main housing 104 incorporates housing 106 which is the housing for fuse 105 (paragraph [0064]). Main housing is directly above the flow through heater sub assembly 115 having the substrate 20 (paragraph [0060], [0061]; figure 6a). There will be inherently atmospheric air within the main housing which surround thermal fuse 105 to establish heat transfer from the substrate and the fuse via convection.
For these reasons, both Yoneda and Deenen teach wherein the conductive element is spaced from the substrate such that heat transfer between the substrate and the conductive element occurs through conduction at the ends of the conductive elements or by convection through the medium surrounding the conductive element.
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(s) 1, 3, 4, 9-11 and 15 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Yoneda (U.S. Pre-Grant Publication No. 2015/0340182).
As per claim 1, Yonedia discloses a heating plate, comprising: a substrate (102; figure 5) with a first face (lower surface shown; figure 5) intended for being in contact with a thermal fluid to be heated (this limitation only deals with intended use and the manner of operating the device does not differentiate apparatus claim from the prior art; see MPEP 2114), and a second face opposite the first face (upper surface shown; figures 5); a resistive element (121) arranged on the substrate (102; figures 5, 6) intended for generating heat in order to heat the thermal fluid; a power supply input port (104a; figure 2A) and an output port (121) to provide a power supply to the resistive element (as shown; figure 2A); a conductive element extending between a first end and a second end, the conductive element being made of a meltable material with a preestablished melting temperature (meltable conductor 108 having one end in contact with electrode 104 and opposing end in contact with electrode 106; figure 5); and wherein the first end of the conductive element is electrically connected to the resistive element and the second end of the conductive element is connected to a power supply input port or output port (one end of meltable conductor 108 is connected to resistor 121 and another end of meltable conductor 108 is connected to terminal 104a; figure 2A), such that the conductive element permits two states: a first operative state establishing electrical continuity between the first end and the second end (as shown; figure 2A); and a second cutoff state wherein the conductive element has been melted because it reached the melting temperature or a temperature higher than the melting temperature, giving rise to the severing of the conductive element, preventing the passage of current (as shown; figure 2B); wherein the conductive element is spaced from the substrate (conductor 108 is shown to be spaced from substrate 102 via electrodes 104 and 106; figure 5) such that heat transfer between the substrate and the conductive element occurs through conduction at the ends of the conductive element (see annotated figure 5 below) or by convection through the medium surrounding the conductive element (inherently, the surrounding air within the enclosure shown in figure 5 would attribute thermal convection to the conductive element 108).

As per claim 10, Yoneda discloses a heating plate according to claim 1, and further discloses wherein the conductive element has releasable fixing means which allow the replacement thereof when the conductive element has reached the second cutoff state (conductor 108 has a low melting point and therefore allows to remove conductor 108 by melting; paragraph [0047]).
