Office Action

§102 §103 §112 §DP
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 . Drawings 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. Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/apply/applying-online/eterminal-disclaimer. Claim 1-18 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-7, 11-13 and 17-20 of copending Application No. 17/844,331. Although the claims at issue are not identical, they are not patentably distinct from each other because the instant and copending claims are drawn to overlapping subject matter. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. Claim Rejections - 35 USC § 112 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. Claims 3 and 15 are 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. Claim 3 recites the limitation wherein each of X1 to X6 is C or wherein at least one of X1 to X6 is N. This does not appear to limit the claim 1 from which it depends. Claim 15 recites specific ligand LB that are not within the scope of claim 1. Claim 1 requires that and at least one RE substituent comprises at least two aliphatic carbon atoms. Many of the structures recited in claim 15 do not meet this limitation. 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 § 102 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. Claims 1-5, 7-8, 10-11 and 13-15 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Xia (US 2015/0090981) (Xia). In reference to claims 1-5, 7-8, 10-11 and 13-15, Xia teaches a compound 8079 that is Ir(La)1(Lb)2 wherein La and Lb are the ligands LA242 and LB18 as shown below (Xia [0056] [0077] [0080] [0081]). PNG media_image1.png 308 430 media_image1.png Greyscale PNG media_image2.png 214 278 media_image2.png Greyscale For Claim 1: Reads on the claimed compound wherein m is 1, n is 2, two RB are isopropyl and the rest are hydrogen, R* is hydrogen, RA is hydrogen, RD is hydrogen, RC is a combination of alkyl and deuterium or hydrogen, E is pyridine and one of RE is an alkyl and the other are hydrogen, X1 is N and X2 to X10 are each C, and wherein condition 2 is true. For Claim 2: Reads on hydrogen, alkyl or deuterated alkyl. For Claim 3: Reads on one of X1 to X6 is N. For Claim 4: Reads on pyridine. For Claim 5: Reads on CR’R”. For Claim 7: Reads on wherein RB has 3 aliphatic carbon atoms and RE has three. For Claim 8: Reads on alkyl ortho. For Claim 10: Reads on the first structure. For Claim 11: Reads on the last structure. For Claim 13: Reads on the first structure. For Claim 14: Reads on row 2 column 5. For Claim 15: Reads on LB121. 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 6, 9 and 17-20 are rejected under 35 U.S.C. 103 as being unpatentable over Xia (US 2015/0090981) (Xia). In reference to claims 6 and 9, Xia teaches the compound as described above for claim 1. Xia further teaches that these materials can include additional substituents on the benzimidazole group (Xia [0056 to [0070]) including the claimed groups. Xia discloses the that encompasses the presently claimed compound, including wherein benzimidazole groups have additional substituents. Each of the disclosed substituents from the substituent groups of Xia are considered functionally equivalent and their selection would lead to obvious variants of the compound. 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 to provide the compound described above, which is both disclosed by Xia and encompassed within the scope of the present claims and thereby arrive at the claimed invention. In reference to claims 17-20, Xia teaches the compound as describe ed above for claim 1 and further teaches its use in an organic electroluminescent device or consumer product comprising an anode, cathode and organic layer comprising the compound and a host compound including the claimed materials (Xia [0026] [0085]). Given that Xia discloses the device structure that encompasses the presently claimed devices, including an organic electroluminescent device or consumer product comprising an anode, cathode and organic layer comprising the compound and a host compound including the claimed materials, it therefore would have been obvious to one of ordinary skill in the art before the effective filing date of the instant application, to use the device configuration, which is both disclosed by Xia and encompassed within the scope of the present claims and thereby arrive at the claimed invention.
