Office Action

§103
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 Arguments Applicant’s arguments, see Applicant’s Remarks pages 11-15, filed 2/19/2026, with respect to the rejections of claims 1-7 and 9-11 under 35 U.S.C. 103 have been fully considered and are persuasive (notably, Applicant’s observation that the example described in US 20210143352 A1 (Yamazaki et al) was noted to use ITSO as its electrode material as opposed to ITO in order to achieve the intended refractive index properties). Therefore, the rejection has been withdrawn. However, upon further consideration, new grounds of rejection are made in view of prior art documents US 20150021627 A1 (Fujita et al) in view of US 20210184123 A1 (Hayano), which teaches that TAPC, a material suggested for the hole transport layer of the present application, is a known alternative hole transport material which would be obvious to use in a light emitting device. Prior art document US 20200227685 A1 (Kyoung et al) in view of Hayano likewise would teach such a configuration, and those teachings are found pertinent to the examination of claims 1-7, 9-12, 16-18, and 22-23. Dependent claims 8, 13-15, and 19-21 are still found to have allowable subject matter. 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 (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 text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claims 1-7 and 9-11 are rejected under 35 U.S.C. 103 as being unpatentable over US patent publications US 20150021627 A1 (Fujita et al hereinafter Fujita) in view of US 20210184123 A1 (Hayano). Regarding claim 1, Fujita discloses a light-emitting device (the device of FIGS. 4-5 ¶ [0054-0055]) comprising: a first reflective film (FIG. 5, reflection layer 26 has high reflectivity ¶ [0125]); a first layer (FIG. 5, dielectric multilayer film 27 ¶ [0126]); a second layer (FIG. 5, positive electrode 31 ¶ [0110]); a third layer (functional layer 32 includes a hole injection transport layer HTL ¶ [0146]); a fourth layer (FIG. 5, functional layer 32 includes light emitting layer EML ¶ [0146]); and a first electrode (FIG. 5, negative electrode 33 ¶ [0110]), wherein the first electrode overlaps with the first reflective film (FIG. 5, negative electrode 33 overlaps reflection layer 26), wherein the fourth layer is positioned between the first electrode and the first reflective film (FIG. 5, EML of layer 32 is between negative electrode 33 and reflection layer 26), wherein the fourth layer comprises a first light-emitting material (a variety of light-emitting materials are suggested for EML ¶ [0157-0168]), wherein the first light-emitting material has an emission spectrum having a peak at a first wavelength (while peak wavelengths are not stated for each material suggested for use in EML, a person of ordinary skill in the art would recognize that each material includes an emission spectrum peak), wherein the third layer is positioned between the fourth layer and the first reflective film (FIG. 6, HTL is located between EML and reflection layer 26 ¶ [0146]), wherein the third layer comprises an organic compound (HTL may comprise a variety of organic materials listed in ¶ [0149-0155]), wherein the second layer is positioned between the third layer and the first reflective film (FIG. 5, positive electrode 31 is between functional layer 32 and reflection layer 26), wherein the second layer has a property of transmitting light with the first wavelength (positive electrode 31 is translucent, allowing the light to transmit ¶ [0129]), wherein the second layer comprises a second electrode (positive electrode 31 is a second electrode), wherein the second layer comprises an element with an atomic number of 21 to 83 at 5 atomic% or higher (positive electrode 31 may be formed of ITO, which is an oxide including Indium and Tin ¶ [0143]; present application ¶ [0199] suggested such a material as suitable for the second electrode), wherein the first layer is positioned between the second layer and the first reflective film (FIG. 5, dielectric multilayer film 27 is between positive electrode 31 and reflection layer 26), wherein the first layer has a property of transmitting light with the first wavelength (light passes through dielectric multilayer film 27 as part of an optical resonance structure ¶ [0135]), wherein the first layer comprises an element with an atomic number of 1 to 20 at 95 atomic% or higher (dielectric multilayer film 27 may be formed of alternating layers of silicon oxide and amorphous silicon, all of which have elements with atomic numbers in the range of 1-20 ¶ [0138-0140]), and wherein the first reflective film reflects light with the first wavelength (reflection layer 26 has high reflectivity to reflect light emitted by EML ¶ [0129]). Fujita did not explicitly disclose that the organic compound has an ordinary refractive index higher than or equal to 1.45 and lower than or equal to 1.75 at a wavelength in a range of 450 nm to 650 nm inclusive, and that the second layer has a higher ordinary refractive index than the first layer and the third layer at the first wavelength, the description of such a parameter for each of their materials for their hole injection transport layer HTL not being of particular importance to the disclosure of their invention; Fujita does suggest certain materials for HTL, among which a “benzidine series” structure is listed (¶ [0149-0150]). In applicant’s disclosure, a number of materials meeting that claim limitation are listed in ¶ [0179-0180] of the present specification (e.g. TAPC ¶ [0180]). However, Hayano discloses a light emitting device wherein a hole transport layer (FIG. 2, hole transport layer HTL ¶ [0050]) may interchangeably be formed of TAPC or a benzidine series derivative NPB (¶ [0050]). TAPC would be recognized as an organic compound that has an ordinary refractive index higher than or equal to 1.45 and lower than or equal to 1.75 at a wavelength in a range of 450 nm to 650 nm inclusive, since applicant’s specification suggested TAPC as a suitable hole transport material (present application ¶ [0180]). Fujita and Hayano both pertain to the field of light emitting devices, placing them in the same field of endeavor as the claimed invention. Therefore, a person of ordinary skill in the art before the effective filing date of the claimed invention would have found it obvious to modify the functional layer of Fujita in view of Hayano by using TAPC as the organic compound comprised by the third layer, whereby the organic compound has an ordinary refractive index higher than or equal to 1.45 and lower than or equal to 1.75 at a wavelength in a range of 450 nm to 650 nm inclusive, because Hayano has indicated that TAPC and a benzidine series compound are known alternative materials which may be used for a hole transport layer; using TAPC may further be found beneficial when considering materials costs and changing market conditions. Having done so, Fujita in view of Hayano further discloses that the second layer has a higher ordinary refractive index than the first layer and the third layer at the first wavelength (in the context of Fujita in view of Hayano, the first layer having dielectric films 27a is formed of silicon oxide Fujita ¶ [0139], the second layer positive electrode 31 is formed of ITO Fujita ¶ [0143], and the third layer is formed of TAPC Hayano ¶ [0050]; these materials are consistent with the disclosed materials taught in present application ¶ [0180, 0199, and 0208], and therefore have the same claimed refractive index properties).

Regarding claim 5, Fujita discloses a light-emitting device (the device of FIGS. 4-5 ¶ [0054-0055]) comprising: a first reflective film (FIG. 5, reflection layer 26 has high reflectivity ¶ [0125]); a first layer (FIG. 5, dielectric multilayer film 27 ¶ [0126]); a second layer (FIG. 5, positive electrode 31 ¶ [0110]); a third layer (functional layer 32 includes a hole injection transport layer HTL ¶ [0146]); a fourth layer (FIG. 5, functional layer 32 includes light emitting layer EML ¶ [0146]); and a first electrode (FIG. 5, negative electrode 33 ¶ [0110]), wherein the first electrode overlaps with the first reflective film (FIG. 5, negative electrode 33 overlaps reflection layer 26), wherein the fourth layer is positioned between the first electrode and the first reflective film (FIG. 5, EML of layer 32 is between negative electrode 33 and reflection layer 26), wherein the fourth layer comprises a first light-emitting material (a variety of light-emitting materials are suggested for EML ¶ [0157-0168]), wherein the first light-emitting material has an emission spectrum having a peak at a first wavelength (while peak wavelengths are not stated for each material suggested for use in EML, a person of ordinary skill in the art would recognize that each material includes an emission spectrum peak), wherein the third layer is positioned between the fourth layer and the first reflective film (FIG. 6, HTL is located between EML and reflection layer 26 ¶ [0146]), wherein the third layer comprises an organic compound (HTL may comprise a variety of organic materials listed in ¶ [0149-0155]), wherein the second layer is positioned between the third layer and the first reflective film (FIG. 5, positive electrode 31 is between functional layer 32 and reflection layer 26), wherein the second layer has a property of transmitting light with the first wavelength (positive electrode 31 is translucent, allowing the light to transmit ¶ [0129]), wherein the second layer comprises a second electrode (positive electrode 31 is a second electrode), wherein the second layer comprises an element with an atomic number of 21 to 83 at 5 atomic% or higher (positive electrode 31 may be formed of ITO, which is an oxide including Indium and Tin ¶ [0143]; present application ¶ [0199] suggested such a material as suitable for the second electrode), wherein the first layer is positioned between the second layer and the first reflective film (FIG. 5, dielectric multilayer film 27 is between positive electrode 31 and reflection layer 26), wherein the first layer has a property of transmitting light with the first wavelength (light passes through dielectric multilayer film 27 as part of an optical resonance structure ¶ [0135]), wherein the first layer comprises an element with an atomic number of 1 to 20 at 95 atomic% or higher (dielectric multilayer film 27 may be formed of alternating layers of silicon oxide and amorphous silicon, all of which have elements with atomic numbers in the range of 1-20 ¶ [0138-0140]), and wherein the first reflective film reflects light with the first wavelength (reflection layer 26 has high reflectivity to reflect light emitted by EML ¶ [0129]). Fujita did not explicitly disclose that the organic compound comprises carbon atoms forming bonds by sp3 hybrid orbitals at higher than or equal to 23 % and lower than or equal to 55 % of the total carbon atoms in a molecule, such details regarding sp3 hybrid orbitals not being discussed in particular detail in the disclosure of Fujita, and that the second layer has a higher ordinary refractive index than the first layer and the third layer at the first wavelength; Fujita does suggest certain materials for HTL, among which a “benzidine series” structure is listed (¶ [0149-0150]). In applicant’s disclosure, a number of materials meeting the claim limitations are listed in ¶ [0179-0180] of the present specification (e.g. TAPC ¶ [0180]). However, Hayano discloses a light emitting device wherein a hole transport layer (FIG. 2, hole transport layer HTL ¶ [0050]) may interchangeably be formed of TAPC or a benzidine series derivative NPB (¶ [0050]). TAPC would be recognized as an organic compound that has carbon atoms forming bonds by sp3 hybrid orbitals at higher than or equal to 23 % and lower than or equal to 55 % of the total carbon atoms in a molecule, since applicant’s specification suggested TAPC as a suitable hole transport material (present application ¶ [0180]). Fujita and Hayano both pertain to the field of light emitting devices, placing them in the same field of endeavor as the claimed invention. Therefore, a person of ordinary skill in the art before the effective filing date of the claimed invention would have found it obvious to modify the functional layer of Fujita in view of Hayano by using TAPC as the organic compound comprised by the third layer, whereby the organic compound has carbon atoms forming bonds by sp3 hybrid orbitals at higher than or equal to 23 % and lower than or equal to 55 % of the total carbon atoms in a molecule, because Hayano has indicated that TAPC and a benzidine series compound are known alternative materials which may be used for a hole transport layer; using TAPC may further be found beneficial when considering materials costs and changing market conditions. Having done so, Fujita in view of Hayano further discloses that the second layer has a higher ordinary refractive index than the first layer and the third layer at the first wavelength (in the context of Fujita in view of Hayano, the first layer having dielectric films 27a is formed of silicon oxide Fujita ¶ [0139], the second layer positive electrode 31 is formed of ITO Fujita ¶ [0143], and the third layer is formed of TAPC Hayano ¶ [0050]; these materials are consistent with the disclosed materials taught in present application ¶ [0180, 0199, and 0208], and therefore have the same claimed refractive index properties).

In applicant’s disclosure, a number of materials for the organic compound are listed in ¶ [0179-0180] of the present specification (e.g. TAPC ¶ [0180]). However, Hayano discloses a light emitting device wherein a hole transport layer (FIG. 2, hole transport layer HTL ¶ [0050]) may be formed of TAPC (¶ [0050]). TAPC would be recognized as an organic compound that has an ordinary refractive index higher than or equal to 1.45 and lower than or equal to 1.75 at a wavelength in a range of 450 nm to 650 nm inclusive, since applicant’s specification suggested TAPC as a suitable hole transport material (present application ¶ [0180]). Kyoung and Hayano both pertain to the field of OLED display devices, placing them in the same field of endeavor as the claimed invention. Therefore, a person of ordinary skill in the art before the effective filing date of the claimed invention would have found it obvious to modify the light emitting region of Kyoung in view of Hayano by using TAPC as the organic compound comprised by the third layer, whereby the organic compound has an ordinary refractive index higher than or equal to 1.45 and lower than or equal to 1.75 at a wavelength in a range of 450 nm to 650 nm inclusive, because Hayano has indicated that TAPC is a known material which may be used for a hole transport layer; using TAPC may further be found beneficial when considering materials costs and changing market conditions. Having done so, Kyoung in view of Hayano further discloses that the second layer has a higher ordinary refractive index than the first layer and the third layer at the first wavelength (in the context of Kyoung in view of Hayano, the first layer being dielectric layer 130 may be silicon oxide Kyoung ¶ [0053], the second layer being electrode 140 may be formed of ITO Kyoung ¶ [0051], and the third layer is formed of TAPC Hayano ¶ [0050]; these materials are consistent with the disclosed materials taught in present application ¶ [0180, 0199, and 0208], and therefore have the same claimed refractive index properties). Regarding claim 5, Kyoung discloses a light-emitting device (FIG. 1, blue pixel 100B) comprising: a first reflective film (FIG. 1, reflection layer 120 in blue pixel 100B ¶ [0052]); a first layer (FIG. 1, dielectric layer 130 ¶ [0046]); a second layer (FIG. 1, first electrode 140 in blue pixel 100B ¶ [0046]); a third layer (FIG. 1, hole transfer layer 152 ¶ [0047]); a fourth layer (FIG. 1, organic emissive layer 153 includes a blue emissive layer ¶ [0047]; said blue emissive layer is considered to be the fourth layer); and a first electrode (FIG. 1, second electrode 170 ¶ [0051]), wherein the first electrode overlaps with the first reflective film (FIG. 1, second electrode 170 overlaps reflection layer 120 at blue pixel 100B), wherein the fourth layer is positioned between the first electrode and the first reflective film (FIG. 1, in blue pixel 100B, organic emissive layer 153 is between electrode 170 and reflection layer 120), wherein the fourth layer comprises a first light-emitting material (organic emissive layer 153 includes the blue emissive layer ¶ [0047], which emits blue light), wherein the first light-emitting material has an emission spectrum having a peak at a first wavelength (since it emits blue light, the blue emissive layer has an emission spectrum peak in a blue wavelength), wherein the third layer is positioned between the fourth layer and the first reflective film (FIG. 1, hole transfer layer 152 is between organic emissive layer 153 and reflection layer 120), wherein the second layer is positioned between the third layer and the first reflective film (FIG. 1, first electrode 140 in blue pixel 100B is between hole transfer layer 152 and reflection layer 120), wherein the second layer has a property of transmitting light with the first wavelength (electrode 140 in blue pixel 100B is a transparent conductive oxide, which transmits light ¶ [0051]), wherein the second layer comprises a second electrode (electrode 140 is an electrode), wherein the second layer comprises an element with an atomic number of 21 to 83 at 5 atomic% or higher (electrode 140 may be formed of ITO ¶ [0051]; present application ¶ [0199] suggested such a material as suitable for the second electrode), wherein the first layer is positioned between the second layer and the first reflective film (FIG. 1, dielectric layer 130 is between electrode 140 and reflection layer 120), wherein the first layer has a property of transmitting light with the first wavelength (dielectric layer 130 is transparent and transmits visible light ¶ [0053]), wherein the first layer comprises an element with an atomic number of 1 to 20 at 95 atomic% or higher (dielectric layer 130 may be silicon oxide ¶ [0053] which consists of elements with atomic numbers in the range of 1-20), and wherein the first reflective film reflects light with the first wavelength (reflection layer 120 reflects visible light ¶ [0052], including the blue light of the first wavelength). Kyoung did not explicitly disclose that the third layer comprises an organic compound, wherein the organic compound comprises carbon atoms forming bonds by sp3 hybrid orbitals at higher than or equal to 23 % and lower than or equal to 55 % of the total carbon atoms in a molecule, such details regarding sp3 hybrid orbitals not being discussed in particular detail in the disclosure of Kyoung, and wherein the second layer has a higher ordinary refractive index than the first layer and the third layer at the first wavelength. In applicant’s disclosure, a number of materials for the organic compound are listed in ¶ [0179-0180] of the present specification (e.g. TAPC ¶ [0180]). However, Hayano discloses a light emitting device wherein a hole transport layer (FIG. 2, hole transport layer HTL ¶ [0050]) may be formed of TAPC (¶ [0050]). TAPC would be recognized as an organic compound that has carbon atoms forming bonds by sp3 hybrid orbitals at higher than or equal to 23 % and lower than or equal to 55 % of the total carbon atoms in a molecule, since applicant’s specification suggested TAPC as a suitable hole transport material (present application ¶ [0180]). Kyoung and Hayano both pertain to the field of OLED display devices, placing them in the same field of endeavor as the claimed invention.
