Office Action

§102
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 . Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claims 1-20 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Sim et al. (KR 10-2021-0050474 A) (refer to translation as provided). Regarding claim 1 and 13, Sim discloses a light emitting element comprising: a first electrode (anode 2, fig. 1); a second electrode (cathode 4, fig. 1) on the first electrode (2); and at least one functional layer (organic material layer 3 that includes multi-layered structure) which is between the first electrode (2) and the second electrode (4) and comprises an amine compound represented by the following formula 1: PNG media_image1.png 182 268 media_image1.png Greyscale Which reads on instant claimed formula 1. Sim further discloses examples of the compound that represented by the disclosed formula 1. For example, Sim discloses the compound can be represented by the following formula: PNG media_image2.png 136 160 media_image2.png Greyscale (page 5) Which reads on instant claimed formula 1 which R1 being an aryl group forming a ring with adjacent group, R2 being hydrogen, R3 being an aryl group, a being 1, L1-L3 each being a direct bond. Regarding claim 2, Sim further discloses that at least one functional layer (3) comprises an emission layer (light emitting layer 8), a hole transport region (5 and/or 6) between the first electrode (2) and the emission layer (8), and an electron transport region (10 and/or 11) between the emission layer (8) and the second electrode (4), and the hole transport region (5 and/or 6) comprises the amine compound. Regarding claim 3, Sim further discloses that the hole transport region (5 and 6) comprises at least one of a hole injection layer (5), a hole transport layer (6), or an electron blocking layer (7), and at least one of the hole transport layer or the electron blocking layer comprises the amine compound. Regarding claims 4 and 14, Sim discloses the compound can be represented by the following formula: PNG media_image2.png 136 160 media_image2.png Greyscale (page 5) which reads on instant claimed formula 1 which R1 being an aryl group forming a ring with adjacent group and R2 being hydrogen. Regarding claims 5 and 15, Sim further discloses that the compound is represented by the following formula: PNG media_image2.png 136 160 media_image2.png Greyscale (page 5) in which claimed R3 is represted by claimed PNG media_image3.png 100 80 media_image3.png Greyscale with R3a being a hydrogen. Regarding claims 6-8 and 16-17, Sim further discloses that the compound is represented by the following formula: PNG media_image2.png 136 160 media_image2.png Greyscale (page 5) Which implies that the L1-L3 being direct bond. Thus all the limitations of instant claims 6-8 are optional. Regarding claim 9-10 and 18-19, Sim further discloses that the compound is represented by following formula: PNG media_image4.png 195 160 media_image4.png Greyscale (page 7) Which reds on instant claimed formula 4-3, which X1 or X2 being O or S. Regarding claim 12 and 20, Sim further discloses that the compound is represented by following formula: PNG media_image4.png 195 160 media_image4.png Greyscale (page 7) Which reds on instant claimed compound D81.
