Office Action

§103 §112
DETAILED ACTION The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . All outstanding objections and rejections, except for those maintained below, are withdrawn in light of applicant's amendment filed on 12/11/2025. 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 new grounds of rejection set forth below are necessitated by applicant's amendment filed on 12/11/2025. In particular, original Claim 1 has been amended to recite new limitations, i.e. at least one of L1 to L3 is a phenylene. Thus, the following action is properly made final. 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. Claim 9 is 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 pre-AIA the applicant regards as the invention. Claim 9 recites that the cyclic compound is “one of Compounds 1 to 5, 15 to 31, 37 to 48, 50, 52 to 61, 71 to 87, 93 to 112, 114 to 119, 121, 123 to 127, 131 to 140”. However, the claim recites Compounds 6 to 14, etc., and further recites Compounds 1 to 5, 15 to 20, etc. twice. That is, it appears that the claim has not properly amended to reflect the desired compounds, thereby rendering the scope of the claim indefinite. Claim Rejections - 35 USC § 103 The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. Claims 1-2, 4, 6-12, and 14-19 are rejected under 35 U.S.C. 103 as being unpatentable over Kim et al (US 2010/0052523, hereafter Kim ‘523) in view of Parham et al (US 2009/0295275). Regarding claim 1, Kim ‘523 discloses an organic light emitting device (Abstract) comprising a first electrode (Abstract), a second electrode (Abstract) facing the first electrode (Figure 1), and an intermediate layer, i.e. an interlayer (Abstract), found between the first electrode and second electrode (Abstract). The intermediate layer comprises an organic emission layer (Abstract), as well as hole transport and hole injection layers ([0050]), i.e. a hole transport region, where the hole transport and hole injection layers are between the light emitting layer and the first electrode ([0050]). The first electrode is a transparent electrode comprising MoOx or WOx ([0010]). Accordingly, the first electrode comprises an inorganic material comprising a metal oxide, where the metal is W or Mo as recited in the present claims. While the reference discloses that the light emitting device comprises a hole transport layer, the reference does not disclose that the hole transport layer comprises the cyclic compound represented by Formula 1 as recited in the present claims. Parham et al discloses an organic light emitting device (Abstract), where the hole transport layer of the device comprises the following compound (Abstract, [0015]-[0016], and Page 9 – Structure 27): PNG media_image1.png 444 464 media_image1.png Greyscale . This compound corresponds to the compound represented by recited Formula (1): PNG media_image2.png 288 530 media_image2.png Greyscale , where CY1, CY2, and CY3 are each C6 carbocyclic groups; X1 is NR4; X2 is NR6; Y1 is N; a1, a2, and a3 are each one (1); Ar1, Ar2, and Ar3 are C6 carbocyclic groups; b1, b2, and b3 are each one (1); n1, n2, and n3 are one (1); n1 + n2 + n3 = 3; R1, R3 and R3 are H; R4 and R6 are C2 alkyl groups. In the compound disclosed by the reference L1, L2 and L3 are single bonds, and therefore, at least one of L1 to L3 is not phenylene as required by the present claims. However, the compound disclosed by the reference is but one embodiment, and attention is directed to the following formula ([0016] – Formula 1): PNG media_image3.png 328 330 media_image3.png Greyscale , where R is disclosed as an aromatic ring system having 5 to 40 aromatic ring atoms ([0020] and [0019]). Such ring systems include biphenyl, i.e. PNG media_image4.png 112 290 media_image4.png Greyscale . Thus, the disclosure of reference encompasses an embodiments where at least one of L1 to L3 in Formula 1 of the claims is a phenylene group. The reference discloses that the compound has excellent hole conducting properties in organic light emitting device ([0011]), high temperature stability ([0014]), and a positive effect on the operating lifetime of the device ([0014]) Given that both Kim ‘523 and Parham et al are drawn to organic light emitting devices comprising hole transport regions, and given that Kim ‘523 does not explicitly prohibit other compounds in the hole transport region, in light of the particular advantages provided by the use and control of the compound as taught by Parham et al, it would therefore have been obvious to one of ordinary skill in the art to include such compounds in the hole transport region of the device disclosed by Kim ‘523 with a reasonable expectation of success. Regarding claim 2, the combined disclosures of Kim ‘523 and Parham et al teach all the claim limitations as set forth above. As discussed above, Kim ‘523 discloses that the light emitting device comprises a first electrode, a second electrode, and an intermediate layer comprising an organic emission layer and hole transport and hole injection layers ([0050]). The device further comprises electron transport and electron injection layer between the emission layer and the second electrode ([0050]). Accordingly, the reference discloses a device with the layers: first electrode / [hole transport and hole injection layers ] / emission layer / [electron injection and electron transport layers ] / second electrode. Accordingly, it is clear that the first electrode is an anode, the second electrode is a cathode. Furthermore, the device comprises an electron transport region, i.e. electron transport and electron injection layers, between the emission layer and the second electrode as recited in the present claims. Regarding claim 4, the combined disclosures of Kim ‘523 and Parham et al teach all the claim limitations as set forth above. Given that Kim ‘523 does not require the presence of p-dopants in the hole transport layer, it is clear that the hole transport layer does not comprise a p-dopant as required by the present claims. Regarding claim 6, the combined disclosures of Kim et al and Parham et al teach all the claim limitations as set forth above. As discussed above, in the compound disclosed by Parham et al, Ar1, Ar2, and Ar3 are benzene groups. Regarding claim 7, the combined disclosures of Kim ‘523 and Parham et al teach all the claim limitations as set forth above. As discussed above, in the compound disclosed by Parham et al, Ar1, Ar2, and Ar3 are benzene groups, corresponding to Formula (2-1) of the claims: PNG media_image5.png 74 100 media_image5.png Greyscale , where Z1 is H. Regarding claim 8, the combined disclosures of Kim ‘523 and Parham et al teach all the claim limitations as set forth above. From the discussion above, Parham et al discloses a compound encompassed by Formula (1-1) of the claims: PNG media_image6.png 298 390 media_image6.png Greyscale , where R11, R13, R21, R23, R24, R31, R33, and R34 are H. Regarding claim 9, the combined disclosures of Kim ‘523 and Parham et al teach all the claim limitations as set forth above. From the discussion above, Parham et al does not disclose Compound 114 of the claims: PNG media_image7.png 164 182 media_image7.png Greyscale , i.e. the reference discloses a compound comprising nitrogen atoms, and not oxygen atoms as required by the compound. However, the compound disclosed by the reference is but one embodiment, and attention is directed to Formula (1) ([0016]): PNG media_image8.png 274 262 media_image8.png Greyscale , where Y can be NR1 or O ([0018]). Accordingly, the disclosure of the reference encompasses an embodiment where Y is O, and therefore, the reference discloses Compound 113 of the present claims. Regarding claim 10, the combined disclosures of Kim ‘523 and Parham et al teach all the claim limitations as set forth above. Additionally, Kim ‘523 discloses that the first electrode comprises a first layer, a second layer, and a third layer ([0018]), where the third layer is between the second layer and the emission layer ([0018]), i.e. the reference discloses in order of stacking: first layer / second layer / third layer / interlayer, as recited in the present claims. The first layer comprises MoOx, WOx, YbOx, ReOx, GeOx ([0116]), i.e. the first layer comprises a first material. The second layer is a reflective layer and comprises Li and Ca ([0116] and [0081]), i.e. the second layer comprises a second material. The third layer comprises a material such as MoOx or WOx, i.e. the recited inorganic material ([0116]). Accordingly, the first material, i.e. MoOx, WOx, YbOx, ReOx, GeOx is different from the second material, i.e. Li or Ca; and the second material, i.e. Li or Ca is different from the inorganic material, i.e. MoOx or WOx as recited in the present claims. Regarding claim 11, the combined disclosures of Kim ‘523l and Parham et al teach all the claim limitations as set forth above. As discussed above, Kim ‘523 discloses in order of stacking: first layer / second layer / third layer / interlayer, and therefore, the first layer is in direct contact with the second layer as recited in the present claims. Regarding claim 12, the combined disclosures of Kim ‘523 and Parham et al teach all the claim limitations as set forth above. As discussed above, Kim et al discloses in order of stacking: first layer / second layer / third layer / interlayer, and therefore, the second layer is in direct contact with the third layer as recited in the present claims. Regarding claim 14, the combined disclosures of Kim ‘523 and Parham et al teach all the claim limitations as set forth above. As discussed above, Kim ‘523 discloses that the first material is MoOx, WOx, YbOx, ReOx, or GeOx, i e. a conductive oxide. Regarding claim 15, the combined disclosures of Kim ‘523 and Parham et al teach all the claim limitations as set forth above. As discussed above, Kim ‘523 discloses that the second material is Li or Ca, i.e. the second material comprises a metal material. Regarding claim 16, the combined disclosures of Kim ‘523 and Parham et al teach all the claim limitations as set forth above. As discussed above, Kim ‘523 discloses that the first material is MoOx, WOx, YbOx, ReOx, or GeOx, and the second material is MoOx or WOx. Accordingly, the first and second material can be different. Regarding claim 17, the combined disclosures of Kim ‘523 and Parham et al teach all the claim limitations as set forth above. As discussed above, Kim ‘523 discloses that the third layer is MoOx or WOx. Accordingly, the third layer consists of the inorganic material as recited in the present claims. Regarding claim 18, the combined disclosures of Kim ‘523 and Parham et al teach all the claim limitations as set forth above. Additionally, Kim ‘523 discloses a display apparatus comprising the organic light emitting device ([0003]). Regarding claim 19, the combined disclosures of Kim ‘523 and Parham et al teach all the claim limitations as set forth above. Additionally, Kim ‘523 discloses that the display apparatus comprises a thin film transistor ([0011]), where the thin film transistor comprises an active layer ([0091]), i.e. an activation layer, a source region ([0091]), i.e. a source electrode, and a drain region ([0091]), i.e. a drain electrode. The first electrode of the organic light emitting device is electrically connected to the drain electrode ([0096]). Claim 3 is rejected under 35 U.S.C. 103 as being unpatentable over Kim et al (US 2010/0052523, hereafter Kim ‘523 and Parham et al (US 2009/0295275) as applied to claims 1-2, 4, 6-12, and 14-19 above, and in view of Yasumoto et al (US 2016/0028034). The discussion with respect to Kim ‘523 and Parham et al as set forth in Paragraph 9 above is incorporated here by reference. Regarding claim 3, the combined disclosures of Kim ‘523 and Parham et al teach all the claim limitations as set forth above. As discussed above, Kim ‘523 discloses WOx. However, the reference does not disclose that x is 2.5 ≤ x ≤ 3.0 as recited in the present claims. Yasumoto et al discloses that tungsten oxide is generally represented by WOx (2 ≤ x < 3) and can exist as a non-stoichiometric compound which can have a variety of compositions, typically WO3, W2O5, W4O11, and WO2 ([0104]). In view of this teaching, it would have been obvious to one of ordinary skill in the art to use any of the typical compositions of tungsten oxide, including WO3 in the electrode disclosed by Kim ‘523, as doing so would amount to nothing more than use of known tungsten oxide for its intended use, in a known environment to accomplish entirely expected results. Claim 20 is rejected under 35 U.S.C. 103 as being unpatentable over Kim et al (US 2010/0052523, hereafter Kim ‘523) and Parham et al (US 2009/0295275) as applied to claims 1-2, 4, 6-12, and 14-19 above, and in view of Kim et al (US 2014/0054555, hereafter Kim ‘555). The discussion with respect to Kim ‘523 and Parham et al as set forth in Paragraph 9 above is incorporated here by reference. Regarding claim 20, the combined disclosures of Kim ‘523 and Parham et al teach all the claim limitations as set forth above. As discussed above, Kim ‘523 discloses an organic light emitting display device. However, the reference does not disclose a color filter as recited in the present claims Kim ‘555 discloses that a conventional organic light emitting display device includes a substrate, a thin film transistor (TFT) formed on the substrate, and a color filter ([0010]). In view of this teaching, it would have been obvious to one of ordinary skill in the art to utilize a color filter in the organic light emitting display device disclosed by Kim ‘523, as doing so would amount to nothing more than use of an element for its intended use, in a known environment to accomplish entirely expected results. Claims 1, 5, 10, and 13 are rejected under 35 U.S.C. 103 as being unpatentable over Parham et al (US 2009/0295275) in view of Kim et al (US 2010/0052523, hereafter Kim ‘523). Regarding claim 1, Parham et al discloses an organic light emitting device (Abstract), comprising an anode, i.e. a first electrode, a cathode, i.e. a second electrode, and a layer, i.e. interlayer, disposed between the anode and cathode ([0052]). The layer comprises a light emitting layer ([0052]) and a hole transport layer, i.e. a hole transport region, between the anode, and light emitting layer ([0052] and [0084]). The hole transport layer of the device comprises the following compound (Abstract, [0015]-[0016], and Page 9 – Structure 27): PNG media_image1.png 444 464 media_image1.png Greyscale . This compound corresponds to the compound represented by recited Formula (1): PNG media_image2.png 288 530 media_image2.png Greyscale , where CY1, CY2, and CY3 are each C6 carbocyclic groups; X1 is NR4; X2 is NR6; Y1 is N; a1, a2, and a3 are each one (1); Ar1, Ar2, and Ar3 are C6 carbocyclic groups; b1, b2, and b3 are each one (1); n1, n2, and n3 are one (1); n1 + n2 + n3 = 3; R1, R3 and R3 are H; R4 and R6 are C2 alkyl groups. In the compound disclosed by the reference L1, L2 and L3 are single bonds, and therefore, at least one of L1 to L3 is not phenylene as required by the present claims. However, the compound disclosed by the reference is but one embodiment, and attention is directed to the following formula ([0016] – Formula 1): PNG media_image3.png 328 330 media_image3.png Greyscale , where R is disclosed as an aromatic ring system having 5 to 40 aromatic ring atoms ([0020] and [0019]). Such ring systems include biphenyl, i.e. PNG media_image4.png 112 290 media_image4.png Greyscale . Thus, the disclosure of reference encompasses an embodiments where at least one of L1 to L3 in Formula 1 of the claims is a phenylene group. The reference teaches all the claim limitations as set forth above; however, the reference does not disclose that the first electrode comprises an inorganic material comprises a metal oxide as recited in the present claims. Kim ‘523 discloses an organic light emitting device (Abstract) comprising a first electrode (Abstract), a second electrode (Abstract), an intermediate layer, i.e. interlayer, (Abstract) formed been the first electrode and second electrode formed on the intermediate layer (Abstract). The first electrode is a transparent electrode comprising MoOx or WOx ([0010]). Accordingly, the first electrode comprises an inorganic material, where the inorganic material comprises a metal oxide, where the metal is W or Mo as recited in the present claims. The transparent electrode comprising MoOx or WOx has improved performance, as well as a switching effect and driving voltage superior to a conventional organic light emitting device (Abstract and [0055]). Given that both Parham et al and Kim ‘523 drawn to organic light emitting devices comprising electrode and given that Kim ‘523 does not explicitly prohibit other compounds for the first electrode, in light of the particular advantages provided by the use and control of MoOx or WOx as taught by Kim ‘523, it would therefore have been obvious to one of ordinary skill in the art to utilize such compounds in the first electrode disclosed by Parham et al with a reasonable expectation of success. Regarding claim 5, the combined disclosures of Parham et al and Kim ‘523 teach all the claim limitations as set forth above. Additionally, it is noted that Parham et al discloses an organic light emitting device where a hole injection layer is not required ([0084] and Table 2). Accordingly, the first electrode is necessarily in direct contact with the hole transport layer as recited in the present claims. Regarding claim 10, the combined disclosures of Parham et al and Kim ‘523 teach all the claim limitations as set forth above. Additionally, Kim ‘523 discloses that the first electrode comprises a first layer, a second layer, and a third layer ([0018]), where the third layer is between the second layer and the emission layer ([0018]), i.e. the reference discloses in order of stacking: first layer / second layer / third layer, as recited in the present claims. The first layer comprises MoOx, WOx, YbOx, ReOx, GeOx ([0116]), i.e. the first layer comprises a first material. The second layer is a reflective layer and comprises Li and Ca ([0116] and [0081]), i.e. the second layer comprises a second material. The third layer comprises a material such as MoOx or WOx, i.e. the recited inorganic material ([0116]). Accordingly, the first material, i.e. MoOx, WOx, YbOx, ReOx, GeOx is different from the second material, i.e. Li or Ca; and the second material, i.e. Li or Ca is different from the inorganic material, i.e. MoOx or WOx as recited in the present claims. Regarding claim 13, the combined disclosures of Parham et al and Kim ‘523 teach all the claim limitations as set forth above. Additionally, it is noted that Parham et al discloses an organic light emitting device where a hole injection layer is not required ([0084] and Table 2). Accordingly, combined disclosures of Parham et al and Kim ‘523 disclose an organic light emitting device where the third layer is necessarily in direct contact with the hole transport layer as recited in the present claims. Response to Arguments Applicant's arguments filed 12/11/2025 have been fully considered but they are not persuasive. In light of the amendments to the claims, the claim objections set forth in the previous Office Action are withdrawn. Applicants argue that the combination of Kim’523 and Parham fail to disclose the compound as recited in claim 1 as amended. However, as discussed in the rejections above, Parham discloses the following compound: PNG media_image1.png 444 464 media_image1.png Greyscale . as well as the following general formula ([0016] – Formula 1): PNG media_image3.png 328 330 media_image3.png Greyscale , where R is disclosed as an aromatic ring system having 5 to 40 aromatic ring atoms ([0020] and [0019]). Such ring systems include biphenyl, i.e. PNG media_image4.png 112 290 media_image4.png Greyscale . Thus, the disclosure of reference encompasses an embodiments where at least one of L1 to L3 in Formula 1 of the claims is a phenylene group. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
