Office Action

§102
DETAILED ACTION Email Communication Applicant is encouraged to authorize the Examiner to communicate via email by filing form PTO/SB/439 either via USPS, Central Fax, or EFS-Web. See MPEP 502.01, 502, 502.03. 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 Amendment Applicant’s amendment of 05/27/2026 does not place the Application in condition for allowance. Claims 1-20 are currently pending. In response to Office Action mailed on 02/27/2026, Applicant has amended claims 1, 20, 12, 13, 19 and 20. Status of the Rejections Due to Applicant’s amendment of claims 1, 20, 12, 13, 19 and 20, all rejections from the Office Action mailed on 02/27/2026 are withdrawn. However, upon further consideration, a new ground of rejection is presented below. Claim Rejections - 35 USC § 102 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 1-20 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by anticipated by Kim et al. (US 2016/0126465 A1). Regarding claims 1 and 13, Kim discloses a light emitting element (organic light emitting device 10, fig. 1) ([0092-0210]) comprising: a first electrode (110, fig. 1 and [0092]); a second electrode (190, fig. 1 and [0092]) on the first electrode (110); and at least one functional layer (organic layer 150, fig. 1 and [0092], that includes a hole transport layer) which is between the first electrode (110) and the second electrode (110) and comprises an amine compound represented by the following formula 1 ([0120] and claims 11-15). PNG media_image1.png 288 328 media_image1.png Greyscale Kim further discloses the compound of generic formula 1 can be represented by compounds 1-199 (see [0057]). Each of compounds 152, 143 and 154 read on instant claimed formula 1. For example, compound 152 read on instant claimed formula 1 (see annotated compound 152) with L1 and L2 being direct bond, L3 being represented by formula 2-2 (see annotated compound 152), Ar2 and Ar3 being represented by claimed formula 3 (see annotated compound 152) with x being O. Compound 152 is not represented by claimed formula 4-3 (see annotated compound 152). PNG media_image2.png 457 590 media_image2.png Greyscale Regarding claim 2, Kim further discloses that at least one functional layer (150) comprises an emission layer ([0097]), a hole transport region between the first electrode (150) and the emission layer (190) ([0098]), and an electron transport region between the emission layer and the second electrode (190) ([0099]), and the hole transport region comprises the amine compound ([0120]). Regarding claim 3, Kim further discloses that the hole transport region ([0098]) comprises a hole injection layer and a hole transport layer ([0101]), and the hole transport layer comprises the amine compound ([0120]). Regarding claims 4 and 14, Kim discloses the compound can be represented by compound 152 (see above) in R1 and R2 being hydrogen. Regarding claims 5 and 15, Kim further discloses that in compound 152, R3 is represented by claimed PNG media_image3.png 100 80 media_image3.png Greyscale with R3a being substituted ring. Regarding claims 6-7 and 16-17, Kim further discloses that in compound 152, formula 3 is represented by formula 3-a (see Ar2 or Ar1 in annotated compound 152). Regarding claim 8, Kim further discloses that in compound 152, L1 and L2 is directed bond and L3 is represented by formula S2-11. Regarding claim 9-10 and 18-19, Kim further discloses that in compound 152 is represented by claimed formula 4-1 with X1 or X2 being O. Regarding claim 11, Kim further discloses the emission layer comprises a host ([0127]) represented by formula 301A ([0151]) Regarding claim 12 and 20, Kim further discloses that the compound is formula 152, which reads on instant claimed compound. Kim further discloses the host compound can be H8 PNG media_image4.png 162 370 media_image4.png Greyscale ([0153]), which reads on instant claimed formula E-1 with R31-R39 each being hydrogen and R40 being a C10 aryl ring (naphthalene ring). Response to Arguments Applicant's arguments with respect to claims 1-20 have been considered but are moot in view of the new ground(s) of rejection as necessitated by the amendments. Applicant argues that Sim fails to disclose as required by claimed formula 1, in which the compound is not represented by formula 4-3. This argument is directed to the claims as amended and is moot in view of new ground of rejection as presented above. 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). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any extension fee pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the date of this final action.
