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 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.
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.
Claim(s) 16-32 are rejected under 35 U.S.C. 103 as being unpatentable over Duan et al. (CN 110407859 A1).
Regarding claims 16-32, Duan et al. teach an organic molecule ( abstract, claims and examples & paragraphs [0002-0050 & 0111-0178]) and its use, and an organic electroluminescent device (OLED) comprising the compound [0176] having a high color purity and high luminous efficiency while achieving emission of green and even yellow light under electroluminescent conditions specifically discloses compound C-189 in [0034]

Further regards to claims 16-23, Organic molecule such as C-189 of Duan et al. do not specifically disclose at least one pair of adjacent groups RI and RII, RII and RIII, RIII and RIV, RV and RVI, RVI and RVII, RVII and RVIII, RIX and RX, RX and RXI, RXI and RXII, RXII and RXIII, RXIV and RXV, RXV and RXVI, RXVI and RXVII and RXVII and RXVIII of claim 1 form an aromatic ring system fused to the benzene ring a, b, c or d and optionally substituted with one or more substituents R5, the adjacent groups at the corresponding positions as instantly claimed and which is optionally substituted with one or more substitutent R5 as instantly claimed. However, Duan et al. recognize in paragraphs [0006-0025] that R21, R22, R23, R24, R25, R26, R27, R28, R29 and R30 are each independently selected from hydrogen, deuterium or a substituted or unsubstituted one of the following groups: a C6-C48 monocyclic or fused ring aromatic hydrocarbon, a C3-C48 monocyclic or fused ring heteroaromatic hydrocarbon, a C6-C30 arylamino, a C3-C30 heteroarylamino, a C1-C36 alkyl, a C1-C6 alkoxy, and R21 to R30 are not simultaneously hydrogen, and two adjacent radicals of R21 to R30may be bonded to each other to form a substituted or unsubstituted one of the following groups: a C1-C10 cycloalkane, a C6-C30 arene, or a C5-C30 heteroarene; R40 is selected from one of a substituted C6-C48 monocyclic arene, a substituted C6-C48 fused ring arene, a substituted or unsubstituted C3-C48 nitrogen-containing monocyclic heteroarene, a substituted or unsubstituted C3 C48 nitrogen-containing fused ring heteroarene; X1 and X2 are each independently NR selected from substituted or unsubstituted one of the following groups: C1-C10 alkyl, C6-C30 monocyclic aromatic hydrocarbon; where substituents are present in the above groups, the substituent groups are independently selected from one of C1-C10 alkyl or cycloalkyl, C2-C10 alkenyl, C1-C6 alkoxy or thioalkoxy groups, C6-C30 monocyclic or fused ring arene groups, C3-C30 monocyclic or fused ring heteroarene groups; See paragraphs [0020-0024]. In formulae (1) to (5) as described above, R40 is represented by the following formula (a): In formula (a): Y1 to Y5 are each independently selected from N, C, CH or CR ', and at least one of them is N; wherein R 'is selected from one of hydrogen, C1-C20 alkyl or alkoxy, C3-C20 cycloalkyl, C6 C30 monocyclic or fused ring aromatic hydrocarbon group, C3-C30 monocyclic or fused ring heteroaromatic hydrocarbon group; R40 is selected from one of fluorobenzene, benzonitrile, diphenylketone, diphenylsulfone, substituted or unsubstituted pyridine, substituted or unsubstituted diazine, substituted or unsubstituted triazine.
Namely, Duan et al. gives the technical implication of substituent selection, Duan et al. gives the technical insight that two adjacent groups in R21 to R30 can be bonded to each other to form a substituted or unsubstituted C6-C30 aromatic hydrocarbon, and R40 can be selected from the above groups, when the person of ordinary skilled in the art faces the technical problem of how to provide more organic luminescent compounds, it would be obvious to one ordinary skilled in the art and is motivated to adopt directly that the substituents of the Summary section of Duan et al. are applied to Duan et al., and the selection of substituent groups close to the nature of the art for modification or replacement, as well as the alteration of the site, on the basis of keeping the structure of the main ring affecting the activity of the compound unchanged, is within the knowledge of ordinary skill in the art.
Further regard to claims 17-23, it would have been obvious to a person of ordinary skilled in the art to be motivated to select compounds of the corresponding substituents and structures for the same reasons as stated above and the disclosure cited in Duan et al. Furthermore, it is within the knowledge of ordinary skill in the art to select the number and positions at which adjacent groups form aromatic rings.
Further regards to claims 24-29 and 31, Duan et al. teach an optoelectronic device comprising a composition comprising organic molecule as a luminescent emitter ( light emitting layer ; Example 1 and [0036). Duane et al. teach the host is a host material for a wide band gap of an organic light-emitting layer, C-67 is a dye and doping concentration is 3 wt.%; (See paragraph [0036]) An organic electroluminescent device comprising a substrate, and an anode layer, a plurality of light-emitting functional layers, and a cathode layer sequentially formed on the substrate; wherein the light-emitting functional layer comprises a hole injection layer, a hole transport layer, a light-emitting layer, and an electron transport layer, the hole injection layer is formed on the anode layer, the hole transport layer is formed on the hole injection layer, the cathode layer is formed on the electron transport layer, with a light-emitting layer between the hole transport layer and the electron transport layer; among these, preferably, the light-emitting layer comprises the compound of the general formula according to the present invention according to any one of the above-mentioned formulae (1) to (4) as instantly claimed. Therefore, it can be seen that the compound of Duan et al. is used as light-emitting layer dopant meeting the limitation of instant claim 1.
Further regards to claims 30 and 32, Duan et al. teach a method for producing an optoelectronic device, the method comprising deposition the organic molecule by a vacuum evaporation method from a solution [0124].
Claim(s) 16-32 are rejected under 35 U.S.C. 103 as being unpatentable over Guo et al. (WO 2020/022751 A1; cited as thereafter Kim et al. ).
Regarding claims 16-32. Kim et al. teach ( see abstract, claims, examples 1-21, comparative examples , experimental examples 1, table 1 and [0015-0112, 0119 & 0524-0527] ) an organic electroluminescent element (OLED) capable of improving efficiency, color properties, lifetime of the element, specifically ([0119]).
The difference between the organic molecule of Kim et al. and the instant claims is RA in the respective radical species as instantly claimed. Nonetheless, Kim et al. teach ( see [0015-0112]) an electromechanical electroluminescent element, the light-emitting layer comprising a compound represented by the following Chemical Formula 1
