OFFICE ACTION:
DETAILED ACTION
Status of the Application
1.	Claims 1 – 20 are pending and are under examination in this action.
2.	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 § 112(b)
3.	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.
4.	Claims 1 – 20 are rejected under 35 U.S.C. 112(b) as being incomplete for omitting essential elements, such omission amounting to a gap between the elements.  See MPEP § 2172.01.
Regarding claims 1 and 20, there are no recited elements that require any “infrared” or “touch” components.  Instead, Applicant has merely recited a “frame” that is labeled as being an “infrared touch frame”.  Based on Applicant’s specification, this particular frame is designed specifically to facilitate infrared touch detection.  However, this infrared touch detection is completely absent from claim 1, aside from the label of the “frame”.  Due to the omission of an infrared touch sensor, and arrangement within the “touch frame assembly”, claims 1 and 20 are indefinite for being incomplete due to the omission of essential elements.
Additionally, the entirety of Applicant’s disclosure is directed towards an infrared touch display.  However, there is no recitation in either of these claims of any display components or even any capability of displaying anything.
Regarding claims 2 – 20, these claims are rejected based on their dependence from claim 1.
5.	Claims 1 – 20 are 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 regards as the invention.
Regarding claim 1, the recitation of “a frame” in line 7 lacks proper antecedent basis.  This claim includes recitations of “a touch frame assembly”, “an infrared touch frame”, and “a frame body”.  It is not clear whether the recitation of “a frame” in line 7 is referring to one of these other “frame” recitations or is directed to another different “frame”.
Regarding claims 1 and 20, the recitations that the “glass cover plate controls an inward concave of the glass cover plate” are redundant and illogical.  It is not clear how a glass cover plate can control its own curvature.  These recitations imply that some force external to the glass cover plate is applying pressure to maintain the curvature of the glass cover plate.  However, the claim requires that the glass cover plate is doing this itself which is impossible.  Therefore, this recitation is indefinite.
For purposes of this Office Action, any element in the prior art that assists the glass cover plate in maintaining its curvature will read on this claim.
Regarding claims 2 – 19, these claims are rejected based on their dependence from claim 1.
Regarding claim 20, the recitation of “a frame” in line 9 lacks proper antecedent basis.  This claim includes recitations of “a touch frame assembly”, “an infrared touch frame”, and “a frame body”.  It is not clear whether the recitation of “a frame” in line 7 is referring to one of these other “frame” recitations or is directed to another different “frame”.
6.	Claims 1 – 20 are rejected under 35 U.S.C. 112(b) as being incomplete for omitting essential structural cooperative relationships of elements, such omission amounting to a gap between the necessary structural connections.  See MPEP § 2172.01.
Regarding claims 1 and 20, the recitation of the “glass cover plate” is incomplete as it fails to include any structural cooperative relationships relative to a display.  It is unclear whether the “glass cover plate” is a light guide of a display, an upper substrate of a display, a cover disposed over a display, or some other element.  This gap in Applicant’s disclosure and claims renders these claims indefinite as it is not clear as to what this “glass cover plate” actually refers.
Regarding claims 2 – 19, these claims are rejected based on their dependence from claim 1.
Examination Precluded
7.	Independent claims 1 and 20 have been rejected above under several grounds for being indefinite and incomplete.  Due to the abundance of issues under 35 USC 112 with regard to independent claims 1 and 20, the scope of these claims cannot be reasonably ascertained.
The numerous rejections to independent claims 1 and 20 under 35 USC 112(b) render Applicant's claims 1 – 20 as being unexaminable for prior art purposes.  Specifically, the incomplete nature of the claims and omitted subject matter renders the scope of Applicant’s claimed invention as indeterminable.
Attempting to apply art would require making assumptions as to what Applicant intended in the absence of support in the specification as originally filed.  In other words, the issues identified above with regard to 35 USC 112(b) render claims 1 – 20 with a scope so undefined that a prior art rejection cannot reasonably be formulated without adding key elements into the claims from the Examiner’s own knowledge.
Therefore, this application is unexaminable with regard to the application of prior art to claims 1 – 20.  The Examiner cannot determine the scope of these claims in any reasonable manner and thus no art will be applied to claims 1 – 20 in this Action.
Pertinent Prior Art
8.	The prior art made of record and not relied upon which is considered pertinent to applicant's disclosure includes: Eriksson et al. (U.S. Pub. 2016/0154533), Lee et al. (U.S. Pub. 2019/0179192), Kwon et al. (U.S. Pub. 2021/0103186), and Globerman (U.S. Pub. 2021/0263603).
Conclusion


NEXT OFFICE ACTION: DETAILED ACTION
Status of the Application
1.	Applicant’s Amendment to the Claims filed October 26, 2023 is received and entered.
2.	Claims 1 – 2, 4, 6 – 8, 10, 14 – 17, 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.	On pages 6 – 7 of the Response, Applicant argues that, due to the Amendments to the claims, the rejections under 35 USC 112(b) are moot.
The Office finds Applicant’s arguments unpersuasive for at least the following reasons.  Applicant’s entire arguments amount to nothing more than saying the rejections under 35 USC 112(b) should be withdrawn because they claims have been amended.  This is the extent of Applicant’s arguments as they are completely devoid of explanation.
There is no analysis as to why the amendments have addressed the underlying grounds of rejection.  There is no articulated reasoning as to why the claims are no longer incomplete, indefinite, or omitting essential structural cooperative relationships of elements.  In sum, Applicant’s arguments have said basically nothing other than “the amendments overcome the rejections”.  However, Applicant is incorrect in this assumption.
While Applicant has added “an infrared emission tube” or “an infrared receiving tube” to independent claims 1 and 20, there is still no connection between these tubes and “touch”, as implicitly required by the recitation of “an infrared touch frame”.
Without a recitation as to the operational connections between these features, it is unclear how a “touch” is supposed to be applied or detected.
Additionally, it is still unclear what the “glass cover plate” actually is.  It remains unclear whether the “glass cover plate” is a light guide of a display, an upper substrate of a display, a cover disposed over a display, or some other element.  Merely adding the words “touch screen” to the “glass cover plate” fails to provide any insight as to what this element actually represents.
Without a specific recitation, supported by the specification as originally filed, as to what is meant by the “touch screen glass cover plate”, it is unclear what art to apply to these claims.
Since Applicant’s amendments have only partially addressed the rejections under 35 USC 112(b), several of the previous rejections are MAINTAINED.
Claim Rejections - 35 USC § 112(b)
5.	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.
6.	Claims 1 – 20 are rejected under 35 U.S.C. 112(b) as being incomplete for omitting essential elements, such omission amounting to a gap between the elements.  See MPEP § 2172.01.
Regarding claims 1 and 20, while Applicant recites an “infrared touch frame” and “a touch screen glass cover plate”, there is no operational connection between these two elements.  Instead, these elements are recited independently of one another and their only connection is related to the positioning of a PCB assembly.
Based on Applicant’s specification, the “infrared touch frame” is designed specifically to facilitate infrared touch detection.  However, this infrared touch detection is completely absent from claim 1, aside from the label of the “frame”.  As recited, it is unclear whether the “touch screen glass cover plate” is even capable of being utilized for infrared touch detection, as implied.
Due to the omission of an operational connection between the “touch frame” and the “glass cover plate”, claims 1 and 20 are indefinite for being incomplete due to the omission of essential elements.
Regarding claims 1 and 20, the claims are completely missing any requirement of any display components even though the entirety of Applicant’s disclosure is directed towards an infrared touch display.  While the “touch screen glass cover plate” references some sort of display, this element in and of itself is insufficient to fill in this particular gap.
Specifically, it is unclear whether the “glass cover plate” is a light guide of a display, an upper substrate of a display, a cover disposed over a display, or some other element.
This gap in Applicant’s disclosure and claims renders these claims indefinite as it is not clear as to what this “touch screen glass cover plate” actually refers.  Without understanding what this element actually is, no prior art can be applied to the claims.
Regarding claims 2 – 19, these claims are rejected based on their dependence from claim 1.
7.	Claims 1 – 20 are 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 regards as the invention.
Regarding claims 1 and 20, the recitations that “an inward concave of the touch screen glass cover plate is controlled through a curvature of the frame body or the fixing structure” is indefinite for at least the following reasons.
The phrase “is controlled” implies some ability to change or modify the recited “curvature” which, as recited, would require the curvature of the frame body or the fixing structure to change.  Such a recitation is indefinite because it is illogical and not supported by the specification as originally filed.
Additionally, this recitation appears to contradict Applicant’s specification as originally filed which merely implies that the curvature of the touch screen glass cover plate is merely maintained by the curvature of the frame body and/or the particular positioning of the fixing structure.
Regarding claims 2 – 19, these claims are rejected based on their dependence from claim 1.
6.	Claims 1 – 20 are rejected under 35 U.S.C. 112(b) as being incomplete for omitting essential structural cooperative relationships of elements, such omission amounting to a gap between the necessary structural connections.  See MPEP § 2172.01.
Regarding claims 1 and 20, the recitation of the “touch screen glass cover plate” is incomplete as it fails to include any structural cooperative relationships relative to a display.  It is unclear whether the “touch screen glass cover plate” is a light guide of a display, an upper substrate of a display, a cover disposed over a display, or some other element.  This gap in Applicant’s disclosure and claims renders these claims indefinite as it is not clear as to what this “touch screen glass cover plate” actually refers.
Regarding claims 2 – 19, these claims are rejected based on their dependence from claim 1.
Drawings
9.	The drawings are objected to under 37 CFR 1.83(a).  The drawings must show every feature of the invention specified in the claims.  Therefore, the “infrared emission tube” and “infrared receiving tube” must be shown or the feature(s) canceled from the claim(s).  No new matter should be entered.
Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance.
Examination Precluded
10.	Independent claims 1 and 20 have been rejected above under several grounds for being indefinite and incomplete.  Due to the abundance of issues under 35 USC 112 with regard to independent claims 1 and 20, the scope of these claims cannot be reasonably ascertained.
The numerous rejections to independent claims 1 and 20 under 35 USC 112(b) render Applicant's claims 1 – 20 as being unexaminable for prior art purposes.  Specifically, the incomplete nature of the claims and omitted subject matter renders the scope of Applicant’s claimed invention as indeterminable.
Attempting to apply art would require making assumptions as to what Applicant intended in the absence of support in the specification as originally filed.  In other words, the issues identified above with regard to 35 USC 112(b) render claims 1 – 20 with a scope so undefined that a prior art rejection cannot reasonably be formulated without adding key elements into the claims from the Examiner’s own knowledge.
Therefore, this application is unexaminable with regard to the application of prior art to claims 1 – 20.  The Examiner cannot determine the scope of these claims in any reasonable manner and thus no art will be applied to claims 1 – 20 in this Action.
Pertinent Prior Art
10.	The prior art made of record and not relied upon which is considered pertinent to applicant's disclosure includes: Eriksson et al. (U.S. Pub. 2016/0154533), Lee et al. (U.S. Pub. 2019/0179192), Kwon et al. (U.S. Pub. 2021/0103186), and Globerman (U.S. Pub. 2021/0263603).
