The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA
DETAILED ACTION
Specification
The amendment filed 02/23/2025 is objected to under 35 U.S.C. 132(a) because it introduces new matter into the disclosure. 35 U.S.C. 132(a) states that no amendment shall introduce new matter into the disclosure of the invention. The added material which is not supported by the original disclosure is as follows:
The phrase wherein “a part of the second metal line 131 overlapping the overlapping part 113 is disposed in the groove 1111”, because a part of the second metal line 131 overlapping the overlapping part 113 is not disposed in the groove 1111, but is rather disposed above the groove 1111, as clearly depicted in figure 5.
Applicant is required to cancel the new matter in the reply to this Office Action.
Claim Rejections - 35 USC § 112
The following is a quotation of the first paragraph of 35 U.S.C. 112(a):
(a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention.
The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112:
The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention.
Claims 9-13, 17, 23-24, 26-32 and 37-38 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention.
There is no support in the specification as filed for the claimed limitation of “a groove is provided in the gate line”, as recited in claim 9.
There is no support in the specification as filed for the claimed limitation of “a part of the second metal line overlapping the overlapping part is disposed in the groove, as recited in claim 26, because a part of the second metal line 131 overlapping the overlapping part 113 is not disposed in the groove 1111, but is rather disposed above the groove 1111, as clearly depicted in figure 5.
There is no support in the specification as filed for the claimed limitation of “a recessed portion aligned with the groove”, as recited in claim 37.
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 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 of this title, 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.
Claims 9-13, 17, 23-24, 32 and 37 are rejected under 35 U.S.C. 103 as being unpatentable over Kim et al. (2004/0109118).

Regarding claims 23 and 24, it would have been obvious to a person of ordinary skill in the art, before the effective filling date of the claimed invention, to form a width of the overlapping part is greater than a width of the planarization part along an extension direction of the second metal line and wherein a length of the overlapping part along an extension direction of the first metal line is greater than a width of the second metal line, in prior art’s device, in order to obtain the advantages of the disclosed display panel by building the structure, respectively.

Response to Arguments
Applicant’s arguments with respect to the claim(s) have been considered but are moot because of the new ground of rejection.
The statement recited in the previous office action wherein “It is noted that a limitation wherein the groove comprises a bottom surface and a slopped inner sidewall connected to the bottom surface would overcome the rejection over Kim et al. (2007/0002193) and Kim et al. (2004/0109118)”, referred to the rejection over the embodiment of figure 4 in Kim et al. (2004/0109118), and not to the embodiment of figures 1-3 in the prior art of Kim et al. (2004/0109118), which is used in the current rejection.
