Office Action

§103 §112
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 § 112(d) The following is a quotation of 35 U.S.C. 112(d): (d) REFERENCE IN DEPENDENT FORMS.—Subject to subsection (e), a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. The following is a quotation of pre-AIA 35 U.S.C. 112, fourth paragraph: Subject to the following paragraph [i.e., the fifth paragraph of pre-AIA 35 U.S.C. 112], a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. Claim 7 is rejected under 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, 4th paragraph, as being of improper dependent form for failing to further limit the subject matter of the claim upon which it depends, or for failing to include all the limitations of the claim upon which it depends. Many of the materials claimed in claim 7 are not within the scope of the amended claim 1 as they do not include an Ar1 or Ar2 represented by the following formulae: PNG media_image1.png 628 454 media_image1.png Greyscale Applicant may cancel the claim(s), amend the claim(s) to place the claim(s) in proper dependent form, rewrite the claim(s) in independent form, or present a sufficient showing that the dependent claim(s) complies with the statutory requirements. Claim Rejections - 35 USC § 103 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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claims 1-10 are rejected under 35 U.S.C. 103 as being unpatentable over Choi et al (KR 2018/0024306) (Choi) in view of Kwong et al (US 2010/0072887) (Kwong). In reference to claims 1-10, Choi teaches a compound of formula (D) as shown below for use in an organic electronic device in a hole transport layer (Choi [0016] [0017]) PNG media_image2.png 212 430 media_image2.png Greyscale for example, wherein in the formula (D), X is O, R7 is a group of A2, m is 0, each other R# is hydrogen, Ar2 is biphenyl and Ar3 is a heteroaryl group including a Se atom (Choi [0046] to [0060]). Choi discloses the compound of formula (D) that encompasses the presently claimed compound, including wherein in the formula (1), X is O, R7 is a group of A2, m is 0, each other R# is hydrogen, Ar2 is biphenyl and Ar3 is a heteroaryl group including a Se atom. Each of the disclosed substituents from the substituent groups of Choi are considered functionally equivalent and their selection would lead to obvious variants of the compound of formula (D). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the instant application, in the absence of unexpected results, to have selected these substituents among those disclosed for the compound of formula (D) to provide the compound described above, which is both disclosed by Choi and encompassed within the scope of the present claims and thereby arrive at the claimed invention. PNG media_image3.png 224 318 media_image3.png Greyscale Choi does not expressly teach that the heteroaryl group including a Se atom is a dibenzoselephene as instantly claimed, but teaches e.g. example compound 128 above and that Se atom is an alternative to O for the heteroaryl group. Furthermore, dibenzoselenophene is a well-known Se comprising heteroaryl group for use in such host materials. With respect to the difference, Kwong teaches, in analogous art, organoselenium compounds such as dibenzoselenophene compounds substituted with arylamine groups of the formula as shown below and further teaches that hosts containing dibenzoselenophene are excellent host and enhancement layer materials for OLEDs (Kwong p. 6; [0069] [0070]). PNG media_image4.png 146 324 media_image4.png Greyscale In light of the motivation of using dibenzoselenophene hosts as described above, it would therefore have been obvious to one of ordinary skill in the art before the effective filing date of the instant application to use the dibenzoselenophene as described by Kwong in order to provide an excellent host material and thereby arrive at the claimed invention. Response to Arguments Applicant’s arguments with respect to the claims 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.
