In the event the determination of the status of the application as subject to AIA is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for a 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.
Claim Rejections - 35 USC § 112
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.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claims 1-10 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Claim 1 recites the limitations “the light extraction member being spaced apart from the second light emitting surface” & “the light extraction member being configured to extract light from the second light emitting surface” in lines 12-14. There is insufficient antecedent basis for the limitation “the second light emitting surface” in the claim. Line 3 of Claim 1 establishes “a plurality of second light emitting surfaces” and does not establish “a second light emitting surface.” It is unclear as to which of the plurality of second light emitting surfaces is being limited by the claim language.
Claims 2-3 are rejected as being dependent on Claim 1.
Claim 4 recites the limitation “the peripheral edge of the light inhibiting layer” in line 3. There is insufficient antecedent basis for this limitation in the claim.
Claim 5 recites the limitation “the light inhibiting layer is coplanar with the light transmitting layer on a side away from the wavelength conversion member” in lines 4-6. The limitation “a side away from the wavelength conversion member” is broad and it is unclear as to which element the side is supposed to pertain to. Additionally it is unclear which portions of the layers are supposed to be coplanar or if both the light transmitting layer and the light inhibiting layer are supposed to be on the same plane.
Claim 6 recites the limitation “the expansion sheet” in lines 7-10. There is insufficient antecedent basis for this limitation in the claim. Line 3 of Claim 6 establishes “two expansion sheets” and does not establish “an expansion sheet.” It is unclear as to which of the two expansion sheets is being limited by the claim language.
Claim 6 recites the limitation “the front surfaces” in line 5. There is insufficient antecedent basis for this limitation in the claim.
Claim 7 recites the limitation “the expansion sheet” in lines 2 & 4. There is insufficient antecedent basis for this limitation in the claim. Line 3 of Claim 6, on which Claim 7 depends, establishes “two expansion sheets” and does not establish “an expansion sheet.” It is unclear as to which of the two expansion sheets is being limited by the claim language.
Claim 7 recites the limitation “the front surface” in line 4. There is insufficient antecedent basis for this limitation in the claim.
Claim 8 recites the limitation “a transparent sealing member is filled between the second light emitting surface” in lines 1-2. There is insufficient antecedent basis for the limitation “the second light emitting surface” in the claim. Line 3 of Claim 1, on which Claim 8 depends, establishes “a plurality of second light emitting surfaces” and does not establish “a second light emitting surface.” It is unclear as to which of the plurality of second light emitting surfaces is being limited by the claim language.
Claim 9 recites the limitation “wherein sealing member is filled between the second light emitting surface” in lines 1-2. There is insufficient antecedent basis for the limitation “the second light emitting surface” in the claim. Line 3 of Claim 1, on which Claim 9 depends, establishes “a plurality of second light emitting surfaces” and does not establish “a second light emitting surface.” It is unclear as to which of the plurality of second light emitting surfaces is being limited by the claim language.
Claim 9 recites the limitation “seals the transparent layer” in line 9. There is insufficient antecedent basis for this limitation in the claim. Line 6 of Claim 9 establishes “transparent layers” and does not establish “a transparent layer.” It is unclear as to which of the transparent layers is being limited by the claim language.
Claim 9 recites the limitation “the transparent sealing member” in line 8. There is insufficient basis for this limitation in the claim. Applicant established “a transparent sealing member” in Claim 8, however Claim 9 does not depend on Claim 8.
Claim 10 recites the limitation “wherein the light emitting device” in line 6. There is insufficient antecedent basis for this limitation in the claim. Line 3 of Claim 10 establishes “a plurality of light emitting devices” and does not establish “a light emitting device.” It is unclear if applicant intends to establish a new light emitting device or to further limit each of the plurality of light emitting devices.
Claim Rejections - 35 USC § 103
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.
Claims 1, 2, 3, 4, 6, 7 are rejected under 35 U.S.C. 103 as being unpatentable over Emura (US 20220099879) in view of Yeh (US 20210313493).
Regarding Claim 1, Emura (see, e.g., figs. 1a-b) shows a light emitting device, comprising:

and two electrical connection members 32 (see, e.g., para.0024) being provided on the electrical connection surface;
a wavelength conversion member 50 (see, e.g., para.0028) stacked on the first light emitting surface, the wavelength conversion member comprising

In addition, Yeh (see, e.g., para.0120) states the configuration of the light extraction member 40 in direct contact with the sidewall 32 of the wavelength conversion member 30 would effectively avoid or reduce the possibility of deterioration of the wavelength conversion member caused by temperature, humidity, and/or a sulfur-containing gas environment.
The configuration of the light extraction member and the light transmitting layer of Yeh is incorporated into the device of Emura.

Regarding Claim 10, Emura, in view of Yeh, shows the light emitting device according to claim 1
Emura, in view of Yeh, however, fails to show a display device, comprising:
a substrate,
a plurality of light emitting devices arranged on the substrate,
a reflective cover surrounding at least one of the light emitting devices,
and a diffusion sheet
and a light-enhancing sheet that are stacked on the plurality of the light emitting devices, wherein the light emitting device comprises

the diffusion sheet 31 abuts against the reflective cover 22 (direct physical contact between 31 and topmost portions of 22),
and the light-enhancing sheet 33 is stacked on a side of the diffusion sheet 31 away from the reflective cover (top side of 31 not in contact with 22).
Li K, however, fails to show
