DETAILED ACTION
The following Office action concerns Patent Application Number 17/296,659. Claims 2, 4-7, 11, 12, 14-16, 19-21, 23, 24 are pending in the application. Claims 4-7, 11, 12, 15, 16, 20, 23 have been withdrawn from consideration as being drawn to non-elected species.
The applicant’s amendment filed October 2, 2025 has been entered.
The previous grounds of rejection over Kurihara et al are withdrawn in light of the applicant’s amendment.
Claim Rejections - 35 USC §§ 102 and 103
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)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention.
(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.
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 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.
Claims 2, 14, 19, 21, 24 are rejected under 35 U.S.C. § 102 as being anticipated by, or, alternatively, under 35 U.S.C. § 103 as being obvious over Inoue et al (US 2014/0291645).
Inoue et al teaches a compound having the formula:

(par. 24). Substituent R1 includes hydrogen (par. 25). Substituent Ht includes the structure:

Greyscale
which is a thiophene ring structure (par. 27, formula Ht-1). Substituents R2-R5 include aryl groups having 6 to 13 carbon atoms (par. 25). The above compound satisfies claimed formulas (G3) and (t1).
The above compound is a host compound in a layer of an organic light emitting device (par. 40; abstract). The above compound is combined with a second compound (called a third substance in the reference) in a light-emitting layer (par. 178). The above compound and the second compound form an exciplex (par. 178, 180). The second compound is also a host material (par. 180). The second compound of the exciplex has a hole-transport property (par. 181). The compounds having hole-transport property include a carbazole compound (par. 145). Therefore, the second compound of the exciplex includes a carbazole compound. The compounds are mixed in a ratio of 1:9 to 9:1 (par. 181). The compounds may be mixed and applied by inkjet or spin coating or dip coating, which do not require evaporation (par. 182).
The limitation “wherein the premixed host material comprising a mixture...is put in one evaporation source” is a statement of the intended use of the composition. The composition of Inoue et al is capable of being put in one evaporation source because it contains all the components of the claimed composition.
In addition, since the two compounds form an exciplex, the second compound must be a host compound as that term is described in the instant application.
In the event that the above disclosure is not sufficiently specific to anticipate the above listed claims, the examiner submits that the selection of the instantly claimed compounds and resultant properties would have been obvious to a person of ordinary skill in the art since Inoue et al teaches a composition comprising each of the recited compounds.
Response to Arguments
The previous grounds of rejection over Kurihara et al have been withdrawn. New grounds of rejection are presented above.
Conclusion
The 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.
