DETAILED ACTION
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 1-5, 8, 11-12, 17 and 20 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by JP2020/095936-A to Chisaka (see attached machine-generated English-language translation).
Regarding claim 1, Chisaka discloses an OLED having the configuration of anode/HIL/HTL/EML1/EML2/ETL/cathode, wherein EML1 or EML2 comprises a quantum dot QD-16 which is InP/ZnS QD surface-functionalized with compound g,

(see the table on page 45 of the original document). The QD is free of cadmium, the ligand is representative of the formula A1-Cy-A2, and claim 1 is therefore anticipated.
Claims 2-5, 8, 11-12, 17 and 20 are unpatentable for the same reason.
Claim Rejections - 35 USC § 103
Claim 6 is rejected under 35 U.S.C. 103 as being unpatentable over JP-2020095936-A to Chisaka.
The device of claim 1 is anticipated as explained above. Regarding claim 6, Chisaka teaches that the ligand can be of the general form of

wherein X1 is a group that includes a carboxyl group or a sulfanyl group. In fact, exemplified ligands include such compounds as

.
Therefore, it would have been obvious to a person of ordinary skill in the art at the time the instant invention was filed to modify the device by, say, replacing the ligand g above with this carboxyl-functional ligand and expect neither difficulty nor criticality. See MPEP § 2143(I)(B).
Allowable Subject Matter
Claims 7, 9, 13-16, 18 and 21-22 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
The following is a statement of reasons for the indication of allowable subject matter: The claimed device is not suggested by Chisaka, which represents the closest prior art of record.
Response to Arguments
Applicant’s arguments have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument.
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 nonprovisional extension fee (37 CFR 1.17(a)) 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 mailing date of this final action.
