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 . Elected Species PNG media_image1.png 322 681 media_image1.png Greyscale A search of the prior art did not show the elected species. Under MPEP 803.02, The search was expanded again to find an examinable species. Examinable Species The examinable species is represented by an Compound 1 (page 6): PNG media_image2.png 324 378 media_image2.png Greyscale Compound 84678 reads on claims 1-2, 4, 7-8, 18, 20-21, 25-27, 32-33. Claims 3, 5, 9, 13, 23, 28, 31 are withdrawn from further consideration as not reading on the examinable species. 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 1-2, 4, 7-8, 18, 20-21, 25-27and 32-33 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 applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 1 recites: wherein each X¹ to X¹⁰ are independently selected from the group consisting of carbon and nitrogen, except that in Formula D, one of the following is true: 1) X⁹ is C; or 2) X⁹ is N and at least one of X¹ to X⁸ or X¹⁰;. X⁹ is C; or 2, is infinite as the metes and bound of “2” is undefined rendering claim 1 indefinite. As a result, claim 1 and all claims treat in this office action requiring the limitation of claim 1 are indefinite. 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. Claim(s) 1-2, 4, 7-8, 18, 20-21, 25-27and 32-33 are rejected under 35 U.S.C. 102 (a)(1) as being anticipated over Beers (US 2014/0225069 A1) A1). Regarding Claims 1-2, 4, 7-8, 21, 26-27, 32-33, Brooks teaches an iridium complex Compound 84678 (page 6): PNG media_image2.png 324 378 media_image2.png Greyscale -- Compound 84678 reads on applicant (LA)h(LB)y(LC)z, h = 1; y = 2; z= 0; LA = Formula C= X1-X13 = CH; Ra = phenyl; Rb = alkyl; Rc = H; LB = X1-X8 = CH; Ra and Rb = H; M = Ir (per claims 1-2, 4, 7-8, 21, 26-27, 32-33). Regarding Claims 18, 20, 25, Beers teaches an OLED may include a substrate 110, an anode 115, a hole injection layer 120, a hole transport layer 125, an electron blocking layer 130, an emissive layer 135, a hole blocking layer 140, an electron transport layer 145, an electron injection layer 150, a protective layer 155, a cathode 160, and a barrier layer 170 (paragraph 29). The emissive layer contain Compound I (paragraph 65) (per claims 18, 25). The host material for the emissive layer includes PNG media_image3.png 1 2 media_image3.png Greyscale PNG media_image4.png 196 354 media_image4.png Greyscale (per claim 20). Response to Amendment The applicant’s arguments with respect to the pending claims have been considered but are moot in view of the new grounds of rejection necessitated by the applicant’s amendment. 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).
