Office Action

§102 §112
DETAILED ACTION The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . All outstanding objections and rejections, except for those maintained below, are withdrawn in light of applicant's amendment filed on 1/28/202. The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior office action. The new grounds of rejection set forth below are necessitated by applicant's amendment filed on 1/28/202. In particular, original Claim 42 has been amended to recite limitations not previously presented. Thus, the following action is properly made final. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 42-45 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor, or for pre-AIA the applicant regards as the invention. Claim 42 recites the limitation “a compound of one of the following structural formulae H-1 to H-8, H-10 to H-16, H-18 to H-32 an H34 to H-130 which renders the scope of the claim indefinite given that claim 42 has been amended deleting formulas H-1 to H-8, H-10 to H-16, H-18 to H-32. Furthermore, it is unclear if Applicants’ intention is to strike through certain formulas, e.g. Formulas H-34 to H-36, H-40, H-43 to H-45 on Page 10 of the claims, or if Applicants’ intention is to strike through all the compounds recited on Page 10, thereby, further rendering the scope of the claim indefinite. 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 42-45 are rejected under 35 U.S.C. 102(a1) as being anticipated by Pflumm et al (US 2012/0326141). Regarding claim 42, Pflumm et al discloses the following compound (Page 10): PNG media_image1.png 118 320 media_image1.png Greyscale , identical to H-4 recited in the present claims. Regarding claim 43, Pflumm et al teaches all the claim limitations as set forth above. Additionally, the reference discloses an organic light emitting device comprising the disclosed compound (Abstract, [0008], and [0071]). Regarding claim 44, Pflumm et al teaches all the claim limitations as set forth above. Additionally, the reference discloses that the compound (disclosed as HTM-1 – [0071]) is present in the hole transport layer of the device ([0008]). Regarding claim 45, Pflumm et al teaches all the claim limitations as set forth above. Additionally, the reference discloses that the compound (disclosed as HTM-1 – [0071]) is present in the hole transport layer of the device ([0008]). In light of the above, it is clear that Pflumm et al anticipates the presently recited claims. Allowable Subject Matter Claims 23-28, 30, 32, and 34-41 are allowable over the “closest” prior art for the reasons set forth below. Pflumm et al discloses an organic light emitting device, i.e. an electronic device, where the hole transport layer comprises a mixture of two (2) hole transporting materials (HTM), i.e. HTM-1 and HTM-2. HTM-1 is a triarylamine compound ([0041]-[0042]) with the formula ([0042] – Formula 1): PNG media_image2.png 118 133 media_image2.png Greyscale , where Ar1, on each occurrence is a monovalent aromatic ring system having 5 to 60 aromatic ring atoms ([0043]). Such ring systems are exemplified as 9,9’-spirobifluorene ([0063]), i.e. PNG media_image3.png 174 195 media_image3.png Greyscale and benzene ([0064]). Compound HTM-2 corresponds to formulas such as. PNG media_image4.png 120 190 media_image4.png Greyscale , PNG media_image5.png 108 224 media_image5.png Greyscale . However, claim 23 has been amended deleting the groups N(R3)2 and NR3. Thus, the compounds encompassed by the present claims can only have a single amine group, while the HMT-2 compounds disclosed by the reference possess two (2) amine groups. Accordingly, the reference discloses compounds outside the scope of the present claims, and the reference does not disclose or suggest the combination of compounds in the hole transport layer as required by claims 23. Response to Arguments Applicant's arguments filed 1/28/2026 have been fully considered but are moot in light of the new grounds of rejection set forth above. In light of the amendments to the claims, the claim objections and 35 U.S.C. 112 (b) rejections set forth in the previous Office Action are withdrawn. Furthermore, in light of the amendments to claim 1, the 35 U.S.C. 103 rejections of claims 23-28, 30, 32, and 34-41 over Pflumm et al and the 35 U.S.C. 102 rejections of the claims over Cho et al, as set forth in the previous Office Action are withdrawn. 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.
