Office Action

§103
CTNF 18/028,844 CTNF 93601 DETAILED ACTION Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. Drawings 06-22 AIA The drawings are objected to because the numbering of views is incorrect. According to 37 C.F.R. 1.84(u) “View numbers must be preceded by the abbreviation “FIG.”". Currently, the view numbers are preceded by the word "FIGURE" . Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Claim Rejections - 35 USC § 103 07-20-aia AIA 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. 07-23-aia AIA 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. 07-20-02-aia AIA 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. 07-21-aia AIA Claim s 1-11 are rejected under 35 U.S.C. 103 as being unpatentable over Kim et al (US 2016/03518167) (Kim) . In reference to claims 1-5 , Kim teaches compounds of the formula 1 as shown below (Kim [0050] PNG media_image1.png 266 428 media_image1.png Greyscale PNG media_image2.png 182 424 media_image2.png Greyscale PNG media_image3.png 40 372 media_image3.png Greyscale PNG media_image4.png 92 378 media_image4.png Greyscale PNG media_image5.png 84 384 media_image5.png Greyscale for example, wherein in the formula 1, R 11 to R 18 are each deuterium (Kim [0051]), R 19 is a group of formula 1E and R 20 is a group of formula 1A as shown above (Kim [0051] [0054]), wherein in the formula 1A, a101 is 1 (Kim [0102]), L101 is formula 3-1 as shown above (Kim [0091]), X 11 and X 12 are each O (Kim [0073]), and A 11 , A 12 and A 13 are each benzene (Kim [0081]; as in compound H122, Kim p 63) and in the formula 1E a102 is 0 (Kim [0102]), R 108 is formula 5-1 (Kim [0137]) . Kim discloses the compound of formula 1 that encompasses the presently claimed compounds, including wherein in the formula 1, R 11 to R 18 are each deuterium, R 19 is a group of formula 1E and R 20 is a group of formula 1A as shown above, wherein in the formula 1A, a101 is 1, L 101 is formula 3-1 as shown above, X 11 and X 12 are each O, and A 11 , A 12 and A 13 are each benzene and in the formula 1E a102 is 0, R 108 is formula 5-1. Each of the disclosed substituents from the substituent groups of Kim are considered functionally equivalent and their selection would lead to obvious variants of the compound of formula 1. 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 1 to provide the compound described above, which is both disclosed by Kim and encompassed within the scope of the present claims and thereby arrive at the claimed invention. For Claim 1: Reads on formula 1 wherein a1 is 8, each of R1 to R8 is hydrogen, L1 is an unsubstituted arylene group and Ar1 is an unsubstituted aryl. For Claim 2: Reads on formula 1-2. For Claim 3: Reads on formula 1-3. For Claim 4: Reads on L1 is phenylene and Ar1 is phenyl. For Claim 5: Reads on the second compound. In reference to claims 6-11 , Kim teaches the device as described above and further teaches that it is used in an organic light emitting device comprising a first electrode, a second electrode and an organic layer between them and wherein the organic layer includes the compound as a host compound and a fluorescent dopant of formula 2, which is an arylamine-based compound and that this configuration leads to improved thermal stability, lower driving voltage and higher efficiency (Kim abstract). While Kim does not exemplify this material in this configuration of a device, it would have been obvious to the ordinarily skilled artisan to have selected a known device configuration from those taught by Kim to use the compound of Kim with the anticipation of proving a device with improved stability, lower driving voltage and higher efficiency. With respect to claim 7 and 8, while the ‘organic layer’ of Kim is not given the same name as those claimed, the name of the layer does not change its position relative to other layers as claimed nor its composition and the organic layer of Kim meets all structural and compositional requirements for the claimed layers.
