OFFICE ACTION:
DETAILED ACTION
Status of the Application
1.	Applicant’s Amendment to the Claims filed June 4, 2024 are received and entered.
2.	Claims 1, 3 – 4, 7, 9, 15 – 16, and 20 are amended.  Claims 1 – 20 are pending and are under examination in this action.
3.	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 Arguments / Amendment
4.	The rejection of claims 15 under 35 USC 112(b) is WITHDRAWN in view of the Amendment.
5.	On page 8 of the Response, Applicant argues that “Eriksson merely discloses a curved display, not an inward concave surface of a first frame edge of the frame body”.
The Office finds Applicant’s argument unpersuasive for at least the following reasons.  As set forth in the embodiments of FIGS. 29 – 32 of Eriksson, frame 403 is illustrated as being curved in a manner similar to display 501.  As clearly illustrated in FIG. 31, the top and bottom edges of frame 403 have an inward concave surface.
Accordingly, Eriksson clearly teaches “an inward concave surface of a first frame edge of the frame body”.  For at least these reasons, Applicant’s argument is unpersuasive.
Claim Rejections - 35 USC § 112(b)
6.	The following is a quotation of 35 U.S.C. 112(b):
(b)  CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
7.	Claim 9 is rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention.
Regarding claim 9, the recitations in lines 2, 5, and 6 of “each of the two first frame edges” lacks sufficient antecedent basis.  It is unclear where the “two first frame edges” has come from since claims 1 and 3, from which claim 9 depend, only refer to a singular first frame edge.
Accordingly, this claim is indefinite as presently recited.  A clarifying amendment is required to overcome this rejection.
Claim Rejections - 35 USC § 103
8.	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.
9.	Claims 1 – 4, 6 – 11, and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Eriksson et al. (U.S. Pub. 2016/0154533).
Regarding claim 1, Eriksson teaches: a touch frame assembly (FIG. 20; paragraph [0075]; touch screen display having a frame), comprising:
a frame body (FIG. 25; paragraph [0081]; surrounding frame 403) comprising a first frame edge, and the first frame edge comprises an inward concave surface (FIGS. 29 – 32; surrounding frame 403 is illustrated as being curved in a manner similar to display 501.  As clearly illustrated in FIG. 31, the top and bottom edges of frame 403 have an inward concave surface.  Therefore, the top edge of frame 403 is interpreted as the “first frame edge”);
a Printed Circuit Board (PCB) assembly arranged in the frame body (FIGS. 24, 25; paragraph [0079]; PCB 502 is arranged in frame 403), wherein the PCB assembly comprises at least one of an infrared emission tube and at least one infrared receiving tube (FIGS. 24, 28; paragraph [0084], [0086]; PCB 502 includes emitters 103 and receivers 203 mounted thereon.  Each emitter 103 and receiver 203 have a lens 407 to facilitate the transmission of infrared light for touch detection.  The combination of infrared emitter 103 and lens 407 is interpreted as an “infrared emission tube”.  The combination of infrared receiver 203 and lens 407 is interpreted as an “infrared receiving tube”);
a touch screen, wherein the touch screen is configured to receive a touch by a user (FIG. 20; paragraph [0075]; display 501 is a touch screen that is therefore configured to receive a user’s touch), the at least one of the infrared emission tube is configured to emit an infrared ray to the infrared receiving tube, an infrared matrix is formed above the touch screen (FIGS. 29, 30; paragraphs [0090], [0091]; emitter 105 emits infrared light from top to bottom which is received by receivers 208 – 210.  Similarly, emitter 104 emits infrared light from left to right which is received by receivers 204 – 207.  Due to having emitters along a top and left surface, and receivers alone a bottom and right surface, an infrared matrix is formed above display 501), and in response to receiving the touch, a position of a contact point on the touch screen is determined (paragraphs [0053], [0054]; a position of a user’s contact point display 501 is determined in response to a user’s touch blocking the transmission of infrared light between emitters and receivers); and
a fixing structure (FIG. 25; paragraph [0079]; rear support 802 and floor 803 together form a “fixing structure”), wherein an inward concave of the touch screen is maintained by a curvature of the inward concave surface (FIGS. 23 – 24, 29 – 32; paragraphs [0079], [0088]; display 501 is a curved display having an inward concave which is inserted into frame 403.  In the embodiments of FIGS. 29 – 32, frame 403 is clearly illustrated as having an inward concave shape as well.  Since display 501 is inserted into frame 403, it is implied that the curved frame 403, and the edges / surfaces thereof, including the “first frame edge”, maintain the curvature of display 501.  This requires only a basic understanding of the main purpose of display frames such as frame 403, i.e., to secure a periphery of a display, such as display 501).
Eriksson fails to explicitly disclose: the touch screen located on an inner side of the PCB assembly; and the fixing structure configured to fix the touch screen to the frame body.
However, Eriksson discloses that frame 403 is divided into an upper cavity in which display 501 is housed and a lower cavity in which PCB 502 and lenses 407 are housed (FIG. 25; paragraph [0079]).  Additionally, Eriksson discloses that mechanical stiffeners may be disposed around a perimeter of a top surface of display 501 (paragraph [0079]).
Additionally, please see MPEP §2144.04(VI)(C) which refers to case law that has held that a particular placement of a claimed element may be an obvious matter of design choice.
In light of the above, it would have been obvious to merely reverse the cavities in which the display 501, PCB 502, and lenses 407 are housed.  In this modification, display 501 would be disposed in the lower cavity between floor 803 and rear support 802 while PCB 502 and lenses 407 would be disposed in the upper cavity between floor 803 and the mechanical stiffeners (see FIG. 25; paragraph [0079]).
As modified, Eriksson teaches: the touch screen located on an inner side of the PCB assembly (FIG. 25; paragraph [0079]; when the elements disposed in upper and lower cavities are reversed, as set forth above, display 501 would be located on an inner side of  PCB 502); and
the fixing structure configured to fix the touch screen to the frame body (FIG. 25; paragraph [0079]; when the elements disposed in upper and lower cavities are reversed, as set forth above, the “fixing structure”, i.e., rear support 802 and floor 803 together, would fix display 501 within frame 403).
It would have been obvious to a person of ordinary skill in the art before the effective filing date of Applicant’s claimed invention to modify the explicit disclosure of Eriksson by merely rearranging the parts thereof to yield predictable results.  Such a modification requires nothing more than a mere rearrangement of parts and would have the added benefit of simplifying the design of frame 403 because it would no longer be required to reflect infrared light from emitters and to receivers.  Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of Applicant’s claimed invention to modify the explicit disclosure of Eriksson by merely rearranging the parts thereof to yield the aforementioned predictable results.
Eriksson fails to explicitly disclose: the touch screen is a touch screen glass cover plate.
However, the Examiner notes that it was well-known and conventional in the art before the effective filing date of Applicant’s claimed invention for a touch display assembly to include a glass cover layer on which a user applies a touch.  This glass cover layer is well-known to either be an upper substrate of the touch display assembly or a protective cover.
Accordingly, it would have been obvious to a person of ordinary skill in the art before the effective filing date of Applicant’s claimed invention to modify the explicit disclosure of Eriksson to include a glass cover layer as a top surface of the disclosed touch display assembly.  Such a modification of Eriksson requires nothing more than utilizing well-known and conventional teachings in the art to fill in the gaps of Eriksson as to the particular material on an outer surface of the disclosed touch display assembly.
Regarding claim 2, Eriksson teaches: wherein the inward concave surface cooperating with the touch screen glass cover plate (FIGS. 29, 30, 32; paragraphs [0079], [0088], [0090]; as set forth above with regard to claim 1, the “first frame edge” of frame 403 has an inward concave surface that maintains the shape of the curved display 501), a part of a surface of the touch screen glass cover plate is attached to the inward concave surface (FIG. 25; paragraph [0079]; as modified above with regard to claim 1, a rear surface of display 501 would be attached to the inward concave surface of the “first frame edge” on an inner side of the top edge of the frame 403), and when the fixing structure fixes the touch screen glass cover plate to the frame body, the touch screen glass cover plate is kept in an inward concave state (FIG. 25; paragraph [0079]; as modified above with regard to claim 1, the placement of display 501 being held in place by the “fixing structure” of rear support 802 and floor 803 would have the effect of supporting, and therefore “keeping” or “maintaining” the inward concave state of display 501, as illustrated).
Regarding claim 3, Eriksson teaches: wherein the inward concave surface is an arc-shaped concave surface (FIGS. 29, 30, 32; paragraph [0079]; the inward concave surface of rear support 802 would match the arc-shape of display 501), wherein the frame body further comprises a second frame edge, and the first frame edge is longer than the second frame edge (FIGS. 29 – 32; as set forth above with regard to claim 1, a top surface of the top edge of frame 403 is interpreted as the “first frame edge”.  With regard to this claim, a top surface of the left edge of frame 403 is interpreted as the “second frame edge”.  As clearly illustrated, the “first frame edge” is longer than the “second frame edge”).
Regarding claim 4, Eriksson teaches: wherein the arc-shaped concave surface has a symmetrical structure (FIGS. 29, 30, 32; paragraphs [0079], [0089]; the inward concave surface of the “first frame edge” would match the arc-shape of display 501 which is symmetrical by having a curved cross-section in the left-to-right direction and a straight cross-section in the top-to-bottom direction), and
wherein a highest point of the arc-shaped concave surface is arranged corresponding to both ends of a first cover plate edge of the touch screen glass cover plate, and a lowest point of the arc-shaped concave surface is arranged corresponding to a midpoint of the first cover plate edge of the touch screen glass cover plate (FIGS. 29, 32; paragraph [0089]; the inward concave surface of rear support 802 would match the arc-shape of display 501 which has a highest point at the left and right ends and a lowest point at a midpoint of the long edges of display 501); or
the highest point of the arc-shaped concave surface is arranged corresponding to both ends of the first frame edge of the frame body, and the lowest point of the arc-shaped concave surface is arranged corresponding to a midpoint of the first frame edge of the frame body (This element is recited in the alternative and is therefore a non-required element of this claim).
Regarding claim 6, Eriksson teaches: wherein an outer contour of the touch screen glass cover plate is rectangular (FIG. 20; paragraphs [0043], [0075]; the outer contour of display 501 is rectangular).
Regarding claim 7, Eriksson teaches: wherein a first cover plate edge of the touch screen glass cover plate is attached to the inward concave surface (FIG. 25; paragraph [0079]; as modified above with regard to claim 1, both the long and short edges of display 501 would be attached to the “inward concave surface”, including that of the “first frame edge”, of frame 403 set forth above with regard to claim 1).
Regarding claim 8, Eriksson teaches: wherein the fixing structure comprises a fixing piece, one end of the fixing piece is pressed on the touch screen glass cover plate, the other end of the fixing piece is fixed on the frame body, so as to keep the touch screen glass cover plate fixed on the frame body (FIG. 25; paragraph [0079]; “fixing structure” includes rear support 802 and floor 803 [fixing piece].  As modified above with regard to claim 1, floor 803 [fixing piece] would include a first end pressed on a surface of display 501 and a second end attached to frame 403.  This would have the effect of keeping display 501 fixed relative to frame 403); or
wherein the fixing structure comprises an adhesive, and the touch screen glass cover plate is adhered to the inward concave surface through the adhesive (This element is recited in the alternative and is therefore a non-required element of this claim).
Regarding claim 9, Eriksson teaches: wherein the frame body comprises a curved frame body in each of the two first frame edges and is recessed inward so as to form the inward concave surface, and a thickness of the frame body is kept consistent (FIGS. 29, 30, 32; paragraph [0089]; frame 403, including the top and bottom [two first frame] edges is curved to match the curvature of display 501.  Based on the totality of the disclosure, including the illustrations, it is suggested that the frame 403 has a consistent thickness around each side of display 501); or
wherein a thickness of a middle portion of each of the two first frame edges of the frame body is greater than that of both ends of each of the two first frame edges of the frame body, so as to form the inward concave surface (This element is recited in the alternative and is therefore a non-required element of this claim).
Regarding claim 10, Eriksson teaches: wherein the frame body is provided with a first step supporting the touch screen glass cover plate, a part of the surface of the touch screen glass cover plate is abutted against a step surface of the first step, and an end of the touch screen glass cover plate is supported by the first step (FIG. 25; paragraph [0079]; as modified above with regard to claim 1, display 501 is disposed in a lower cavity of frame 403 between rear support 802 and floor 803.  The lower cavity of frame 403 is interpreted as a “first step” which supports display 501.  As modified above with regard to claim 1, a side of display 501 would be abutted against, and therefore supported by, the “first step”).
Regarding claim 11, Eriksson teaches: wherein the frame body comprises a first mounting groove, and the PCB assembly is arranged in the first mounting groove (FIG. 25; paragraph [0079]; as modified above with regard to claim 1, PCB 502 is disposed in the upper cavity [first mounting groove] of frame 403 between floor 803 and mechanical stiffeners).
Regarding claim 20, Eriksson teaches: a device (FIG. 20; paragraph [0075]; touch screen display).
Eriksson fails to explicitly disclose: the device is an interactive white board that comprises a backlight module arranged on an inner side of a touch frame assembly.
However, the Examiner notes that it was well-known and conventional in the art before the effective filing date of Applicant’s claimed invention for an infrared touch display assembly to be utilized as an interactive white board.
Additionally, the Examiner notes that it was well-known and conventional in the art before the effective filing date of Applicant’s claimed invention for a display assembly to include a backlight module.
When these well-known and conventional teachings are applied to Eriksson, the device would be an interactive white board that includes a backlight module as part of display 501 of Eriksson, which would therefore be disposed on an inner side of the “touch frame assembly” rejected above with regard to claim 1.
Accordingly, it would have been obvious to a person of ordinary skill in the art before the effective filing date of Applicant’s claimed invention to modify the explicit disclosure of Eriksson such that the device as a whole is used as an interactive white board and the display therefore includes a backlight.  Such a modification of Eriksson requires nothing more than utilizing well-known and conventional teachings in the art to fill in the gaps of Eriksson as to the particular usage of the disclosed device and the particular mechanism for illuminating the display thereof.
The remainder of this claim is identical to the subject matter rejected above with regard to claim 1.  Accordingly, the remainder of this claim is rejected for at least the same reasons set forth above with regard to claim 1.  A duplication of the above rejection is not included in this Office Action for the purpose of brevity.
10.	Claim 5 is rejected under 35 U.S.C. 103 as being unpatentable over, as applied to claim 3 above, in view of Chi et al. (U.S. Pub. 2015/0324045).
Regarding claim 5, Eriksson fails to explicitly disclose: wherein a height difference between a highest point of the arc-shaped concave surface and a lowest point of the arc-shaped concave surface is H, and the H is between 0.5 mm and 5 mm.
However, Chi teaches: wherein a height difference between a highest point of the arc-shaped concave surface and a lowest point of the arc-shaped concave surface is H, and the H is between 0.5 mm and 5 mm (FIG. 1B; paragraphs [0028], [0029], [0036]; a protrusion height H, which is a difference between the highest point and lowest point of a convex or concave curved surface 112 which is a touch surface of a curved touch display device, may be between 2 – 10 mm).
Additionally, please see MPEP §2144.05(I) which refers to case law that has held that where claimed ranges “overlap or lie inside ranges disclosed by the prior art”, a prima facie case of obviousness exists.  See In re Wertheim, 541 F.2d 257, 191 USPQ 90 (CCPA 1976).
It would have been obvious to a person of ordinary skill in the art before the effective filing date of Applicant’s claimed invention to combine the known teachings of Eriksson and Chi to yield predictable results.  More specifically, the teachings of a concave touch display, as taught by Eriksson, are known.  Additionally, the teachings of a concave touch display having a curvature height difference of between 2 – 10 mm, as taught by Chi, are known as well.  The combination of the known teachings of Eriksson and Chi would yield the predictable result of a concave touch display having a curvature height difference of between 2 – 10 mm.  In other words, it would have been obvious to merely utilize the particular parameters regarding the degree of curvature and resulting height difference, as taught by Chi, to make the disclosed device of Eriksson.  Such a combination merely requires applying a known height difference caused by curvature of one concave touch display, as taught by Chi, to another concave touch display of Eriksson to fill in the gaps in the disclosure thereof.  Therefore, it  would have been obvious to a person of ordinary skill in the art before the effective filing date of Applicant’s claimed invention to combine the known teachings of Eriksson and Chi to yield the aforementioned predictable results.
11.	Claim 12 is rejected under 35 U.S.C. 103 as being unpatentable over Eriksson, as applied to claim 11 above, in view of Yaakoby et al. (U.S. Pub. 2009/0322696).
Regarding claim 12, Eriksson teaches: wherein a wall of the first mounting groove is provided with a slot and a second step (FIG. 25; paragraph [0079]; as modified above with regard to claim 1, PCB 502 is disposed in the upper cavity [first mounting groove] of frame 403 between floor 803 and mechanical stiffeners.  The portion of “upper cavity” that corresponds to an interior surface of frame 403 and the mechanical stiffeners is interpreted as a “slot”.  The portion of “upper cavity” that corresponds to floor 803 is interpreted as a “second step”).
Eriksson fails to explicitly disclose: one end of the PCB assembly is clamped with the slot, and the other end of the PCB assembly is bonded with a step surface of the second step.
However, Yaakoby discloses that a PCB may be fixed / attached to another element using clamps or adhesives (paragraphs [0065], [0100]).
The combination of Eriksson and Yaakoby teaches: one end of the PCB assembly is clamped with the slot (the “slot” may secure the end of the PCB that is closest to or against an interior surface of frame 403 [Eriksson] using a clamp [Yaakoby]), and the other end of the PCB assembly is bonded with a step surface of the second step (the “second step” may secure the end of the PCB that is farthest from an interior surface of frame 403 [Eriksson] using an adhesive [Yaakoby] which would bond the “second step” to PCB 502).
It would have been obvious to a person of ordinary skill in the art before the effective filing date of Applicant’s claimed invention to combine the known teachings of Eriksson and Yaakoby to yield predictable results.  More specifically, the teachings of a concave touch display having a PCB assembly disposed in an upper cavity having a slot and a second step, as taught by Eriksson, are known.  Additionally, the teachings of a PCB that is fixed / attached to another element using clamps or adhesives, as taught by Yaakoby, are known as well.  The combination of the known teachings of Eriksson and Yaakoby would yield the predictable result of a concave touch display having a PCB assembly disposed in an upper cavity having a slot that is clamped to a first end of the PCB assembly and a second step that is bonded to a second end of the PCB assembly via an adhesive.  In other words, it would have been obvious to merely utilize well-known and conventional means of clamps and an adhesive, as taught by Yaakoby, for securing the PCB assembly within the upper cavity of Eriksson.  Such a combination merely requires applying known techniques of securing a PCB, as disclosed by Yaakoby, to the particular PCB assembly of Eriksson in its position as rendered obvious above with regard to claim 1.  Therefore, it  would have been obvious to a person of ordinary skill in the art before the effective filing date of Applicant’s claimed invention to combine the known teachings of Eriksson and Yaakoby to yield the aforementioned predictable results.
12.	Claim 13 is rejected under 35 U.S.C. 103 as being unpatentable over Eriksson, as applied to claim 11 above, in view of Huang (U.S. Pub. 2022/0113832).
Regarding claim 13, Eriksson fails to explicitly disclose: wherein the touch frame assembly further comprises a filter bar.
However, Huang teaches: wherein the touch frame assembly further comprises a filter bar (FIG. 2; paragraph [0043]; infrared filter strips 214 filter light waves outside the infrared band emitted by the infrared emitting tubes of infrared touch module 204 to reduce the interference of other electromagnetic spectrum bands to the infrared touch module 204).
It would have been obvious to a person of ordinary skill in the art before the effective filing date of Applicant’s claimed invention to combine the known teachings of Eriksson and Huang to yield predictable results.  More specifically, the teachings of a touch display assembly having infrared emitters and receivers for detecting touch input, as taught by Eriksson, are known.  Additionally, the teachings of a touch display assembly having infrared filter strips that reduce interference of infrared emitters and receivers for detecting touch input, as taught by Huang, are known as well.  The combination of the known teachings of Eriksson and Huang would yield the predictable result of a touch display assembly having infrared filter strips that reduce interference of infrared emitters and receivers for detecting touch input.  In other words, it would have been obvious to merely incorporate the infrared filter strips of Huang into the device of Eriksson to improve performance of the infrared touch detection by reducing interference.  Therefore, it  would have been obvious to a person of ordinary skill in the art before the effective filing date of Applicant’s claimed invention to combine the known teachings of Eriksson and Huang to yield the aforementioned predictable results.
Neither Eriksson nor Huang explicitly disclose: the filter bar is mounted on a notch of the first mounting groove.
However, the Examiner notes that it was well-known and conventional in the art before the effective filing date of Applicant’s claimed invention for elements to be secured using a notch-type structure.
Accordingly, it would have been obvious to a person of ordinary skill in the art before the effective filing date of Applicant’s claimed invention to modify the combination of Eriksson and Huang such that the filter bar is secured in the touch frame assembly using a well-known notch-type structure.  Such a modification of the combination of Eriksson and Huang requires nothing more than utilizing well-known and conventional teachings in the art as to how the filter bar, as taught by Huang, would be physically incorporated and secured to Eriksson’s disclosed touch display assembly.
13.	Claims 14 – 15 and 17 – 19 are rejected under 35 U.S.C. 103 as being unpatentable over Eriksson, as applied to claim 11 above, in view of Lee et al. (U.S. Pub. 2017/0192596).
Regarding claim 14, Eriksson fails to explicitly disclose: wherein one or more support pad is provided between the touch screen glass cover plate and the frame body, and the one or more support pad generates a force that causes the touch screen glass cover plate to be recessed inward, so that the touch screen glass cover plate is recessed inward.
However, Lee discloses a module supporting member 250 that is disposed between a display 100 and a housing plate 510 (FIGS. 1, 19; paragraphs [0164], [0165]).
The combination of Eriksson and Lee teaches: wherein one or more support pad is provided between the touch screen glass cover plate and the frame body, and the one or more support pad generates a force that causes the touch screen glass cover plate to be recessed inward, so that the touch screen glass cover plate is recessed inward (Eriksson; FIGS. 25, 29, 30, 32; paragraph [0079]; when the elements disposed in upper and lower cavities are reversed, as set forth above, display 501 would be disposed between rear support 802 and floor 803 of frame 403.  Lee; FIGS. 1, 19; paragraphs [0164] – [0167]; a module supporting member 250 may optionally be disposed along the entirety of the long sides of the device between a display 100 and a housing plate 510.  Module supporting member 250 may be a double-sided adhesive foam pad which would attach display module 100 to housing plate 510 and provide elastic restoring force to display module 100 which allows display module 100 to curve inward as described.  When these teachings are combined, Eriksson would be modified to include the module supporting member 250 between display 501 and floor 803 along the long sides thereof [top and bottom].  Module supporting member 250 would therefore have the effect of further supporting the inward recess of display 501).
It would have been obvious to a person of ordinary skill in the art before the effective filing date of Applicant’s claimed invention to combine the known teachings of Eriksson and Lee to yield predictable results.  More specifically, the teachings of a touch display assembly having a display disposed between a rear support and a floor of a frame, as taught by Eriksson as modified above with regard to claim 1, are known.  Additionally, the teachings of a display assembly that includes an adhesive foam pad that secures a display to a housing, as taught by Lee, are known as well.  The combination of the known teachings of Eriksson and Lee would yield the predictable result of a touch display assembly having a display disposed between a rear support and a floor of a frame and an adhesive foam pad disposed between the display and the floor of the frame along the long sides thereof [top and bottom].  Such a combination would result in the inward recess of display 501 being further supported by the adhesive foam pad in addition to the support provided by the curved frame.  In other words, it would have been obvious to include the adhesive foam pad of Lee in conjunction with the curved frame of Eriksson to improve and increase the support of the curvature of the display 501.  Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of Applicant’s claimed invention to combine the known teachings of Eriksson and Lee to yield the aforementioned predictable results.
Regarding claim 15, Eriksson teaches: wherein an outer contour of the touch screen glass cover plate is rectangular (FIG. 20; paragraphs [0043], [0075]; the outer contour of display 501 is rectangular).
Eriksson fails to explicitly disclose: wherein when the number of the one or more support pad is two, each of the two support pads is arranged at a midpoint of each of two first cover plate edges of the touch screen glass cover plate; and when the number of the one or more support pad is more than two, the support pads are evenly arranged along the two first cover plate edges of the touch screen glass cover plate at intervals.
However, Lee teaches: wherein when the number of the one or more support pad is two, each of the two support pads is arranged at a midpoint of each of two first cover plate edges of the touch screen glass cover plate (FIGS. 1, 19; paragraph [0164]; there is a module supporting member 250 disposed on both a left and right side [i.e., two module support members 250] along the midpoint of the long [cover plate] edges of the display device); and
when the number of the one or more support pad is more than two, the support pads are evenly arranged along the two first cover plate edges of the touch screen glass cover plate at intervals (This recitation is interpreted as being an optional element recited in the alternative because only one of this element and the previous element can exist in the touch frame assembly at a time).
It would have been obvious to a person of ordinary skill in the art before the effective filing date of Applicant’s claimed invention to combine the known teachings of Eriksson and Lee to yield predictable results for at least the reasons set forth above with regard to claim 14.
Regarding claim 17, Eriksson teaches: wherein the fixing structure comprises a fixing piece, one end of the fixing piece is pressed on the touch screen glass cover plate, the other end of the fixing piece is fixed on the frame body, so as to keep the touch screen glass cover plate fixed on the frame body (FIG. 25; paragraph [0079]; “fixing structure” includes rear support 802 and floor 803 [fixing piece].  As modified above with regard to claim 1, floor 803 [fixing piece] would include a first end pressed on a surface of display 501 and a second end attached to frame 403.  This would have the effect of keeping display 501 fixed relative to frame 403).
Regarding claim 18, Eriksson fails to explicitly disclose: wherein the support pad is adhered to the frame body.
However, Lee teaches: wherein the support pad is adhered to the frame body (FIG. 19; paragraph [0167]; module supporting member 250 may be a double-sided adhesive foam pad which would attach display module 100 to housing plate 510.  Accordingly, module supporting member 250 is adhered to housing plate 510).
It would have been obvious to a person of ordinary skill in the art before the effective filing date of Applicant’s claimed invention to combine the known teachings of Eriksson and Lee to yield predictable results for at least the reasons set forth above with regard to claim 14.
Regarding claim 19, Eriksson fails to explicitly disclose: wherein a material of the support pad is plastic or foam (FIG. 19; paragraph [0167]; module supporting member 250 may be a double-sided adhesive foam pad).
However, Lee teaches: wherein a material of the support pad is plastic or foam.
It would have been obvious to a person of ordinary skill in the art before the effective filing date of Applicant’s claimed invention to combine the known teachings of Eriksson and Lee to yield predictable results for at least the reasons set forth above with regard to claim 14.
Allowable Subject Matter
14.	Claim 16 is objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
