Office Action

§112
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 . Election/Restrictions Applicants elected the following compound without traverse in the reply filed on 2 March 2026: PNG media_image1.png 312 253 media_image1.png Greyscale . However, the aforementioned compound is not within the scope of the compound of the present formula I. The Examiner spoke with applicant’s representative, i.e., Lindsay N. Kandow, on 24 March 2026, and confirmed that applicants elect the following compound without traverse: PNG media_image2.png 250 217 media_image2.png Greyscale wherein each of the substituents R10, R20, R30, and R40 therein is hydrogen. 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 1-20 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 is rejected as being vague and indefinite when it recites “wherein RA, RB, RC, and RD each independently represent mono to the maximum amount of substitution, or no substitution” (emphasis added); the scope of the protection sought by “no substitution” is not clear, particularly in light of the substituent definitions which follow that phrase. Claim 1 fails to particularly point out and distinctly claim the substituents RA, RB, RC, and RD in the claimed compound of formula I. Claim 19 is also rejected as being vague and indefinite when it recites “wherein RA, RB, RC, and RD each independently represent mono to the maximum amount of substitution, or no substitution” (emphasis added), as it fails to particularly point out and distinctly claim the substituents RA, RB, RC, and RD in the compound of formula I contained in the organic layer of the claimed organic light emitting device. Similarly, claim 20 is rejected as being vague and indefinite when it recites “wherein RA, RB, RC, and RD each independently represent mono to the maximum amount of substitution, or no substitution” (emphasis added), as it fails to particularly point out and distinctly claim the substituents RA, RB, RC, and RD in the compound of formula I contained in the organic layer of the organic light emitting device contained in the claimed consumer product. Claims 2 and 3 are rejected as being vague and indefinite when they each recite “wherein exactly one of L1-L4 is a one atom linker” (emphasis added); the scope of the protection sought by and antecedent basis of “one atom linker” is not clear. Claims 2 and 3 each fail to particularly point out and distinctly claim the substituents L1 - L4 in the claimed compound of formula I, i.e., that at least one of the substituents L1 - L4 is O, S, or Se. Claim 2 is rejected as being vague and indefinite when it recites “at least one of Rings A-D is a 5-membered ring and no two adjacent rings selected from Rings A-D are both a pyrrole or both a triazole” (emphasis added); the scope of the protection sought by and antecedent basis of “no two adjacent rings selected from Rings A-D” is not clear. Claim 2 fails to particularly point out and distinctly claim the rings A through D in the claimed compound of formula I. Claim 6 is rejected as being vague and indefinite when it recites “wherein L1 and L2 are both one atom linkers” (emphasis added); the scope of the protection sought by and antecedent basis of “one atom linker” is not clear. Claim 6 fails to particularly point out and distinctly claim the substituents L1 and L2 in the claimed compound of formula I, i.e., that at least one of the substituents L1 and L2 are each O, S, or Se. Claim 15 is rejected as being vague and indefinite when it recites “wherein at least one of T1-T12 is selected from the group consisting of N, B, O, S, and Se; wherein at least two of T1″-T3″ are selected from the group consisting of N, NR, BR, BRR′, SiRR′, CRR′, O, S, Se, PR, SO, SO2, and P(O)R; wherein at least two of T4″-T6″ are selected from the group consisting of N, NR, BR, BRR′, SiRR′, CRR′, O, S, Se, PR, SO, SO2, and P(O)R; wherein at least two of T7″-T9″ are selected from the group consisting of N, NR, BR, BRR′, SiRR′, CRR′, O, S, Se, PR, SO, SO2, and P(O)R; wherein at least one of T1′″-T3′″ is selected from the group consisting of N, NR, BR, BRR′, SiRR′, CRR′, O, S, Se, PR, SO, SO2, and P(O)R” (emphasis added); the scope of the protection sought is not clear. A broad range or limitation together with a narrow range or limitation that falls within the broad range or limitation (in the same claim) may be considered indefinite if the resulting claim does not clearly set forth the metes and bounds of the patent protection desired. See MPEP § 2173.05(c). In the present instance, claim 15 recites the broad recitation “wherein T1-T12, T1′-T14′, T1″-T9″, and T1′″-T3′″ are each independently selected from N, NR, BR, BRR′, SiRR′, CR, C═X, CRR′, O, S, Se, PR, SO, SO2, and P(O)R”, and the claim also recites “wherein at least one of T1-T12 is selected from the group consisting of N, B, O, S, and Se; wherein at least two of T1″-T3″ are selected from the group consisting of N, NR, BR, BRR′, SiRR′, CRR′, O, S, Se, PR, SO, SO2, and P(O)R; wherein at least two of T4″-T6″ are selected from the group consisting of N, NR, BR, BRR′, SiRR′, CRR′, O, S, Se, PR, SO, SO2, and P(O)R; wherein at least two of T7″-T9″ are selected from the group consisting of N, NR, BR, BRR′, SiRR′, CRR′, O, S, Se, PR, SO, SO2, and P(O)R; wherein at least one of T1′″-T3′″ is selected from the group consisting of N, NR, BR, BRR′, SiRR′, CRR′, O, S, Se, PR, SO, SO2, and P(O)R” which is the narrower statement of the range/limitation. The claim(s) are considered indefinite because there is a question or doubt as to whether the feature introduced by such narrower language is (a) merely exemplary of the remainder of the claim, and therefore not required, or (b) a required feature of the claims. Claim 15 fails to particularly point out and distinctly claim the substituents T1-T12, T1′-T14′, T1″-T9″, and T1′″-T3′″ in the claimed compound of formula I. Claim 17 is rejected as being vague and indefinite when it recites the following (simply a representative example of the recitation in the claim) PNG media_image3.png 520 938 media_image3.png Greyscale ; the scope of the protection sought by these columns is not clear. Claim 17 fails to particularly point out and distinctly claim the compound of formula I. Rejoinder The species elected 24 March 2026 is allowable. Pursuant to the procedures set forth in MPEP § 821.04(a), the election of species requirement as set forth in the Office action mailed on 2 January 2026 is hereby withdrawn and all species are hereby rejoined and fully examined for patentability under 37 CFR 1.104. In view of the withdrawal of the election of species requirement, applicant(s) are advised that if any claim presented in a divisional application is anticipated by, or includes all the limitations of, a claim that is allowable in the present application, such claim may be subject to provisional statutory and/or nonstatutory double patenting rejections over the claims of the instant application. Once the election of species requirement is withdrawn, the provisions of 35 U.S.C. 121 are no longer applicable. See In re Ziegler, 443 F.2d 1211, 1215, 170 USPQ 129, 131-32 (CCPA 1971). See also MPEP § 804.01. Allowable Subject Matter Claims limited to a compound represented by any one of the following formulae would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action: PNG media_image4.png 277 228 media_image4.png Greyscale PNG media_image5.png 280 190 media_image5.png Greyscale PNG media_image6.png 286 250 media_image6.png Greyscale PNG media_image7.png 310 252 media_image7.png Greyscale PNG media_image8.png 317 313 media_image8.png Greyscale PNG media_image9.png 305 231 media_image9.png Greyscale PNG media_image10.png 317 229 media_image10.png Greyscale PNG media_image11.png 323 259 media_image11.png Greyscale PNG media_image12.png 314 274 media_image12.png Greyscale PNG media_image13.png 228 360 media_image13.png Greyscale PNG media_image14.png 247 287 media_image14.png Greyscale PNG media_image15.png 263 216 media_image15.png Greyscale PNG media_image16.png 261 229 media_image16.png Greyscale PNG media_image17.png 257 215 media_image17.png Greyscale PNG media_image18.png 246 248 media_image18.png Greyscale PNG media_image19.png 253 239 media_image19.png Greyscale PNG media_image20.png 252 269 media_image20.png Greyscale PNG media_image21.png 220 243 media_image21.png Greyscale PNG media_image22.png 296 273 media_image22.png Greyscale PNG media_image23.png 304 259 media_image23.png Greyscale PNG media_image24.png 224 283 media_image24.png Greyscale PNG media_image25.png 233 280 media_image25.png Greyscale PNG media_image26.png 228 281 media_image26.png Greyscale PNG media_image27.png 223 286 media_image27.png Greyscale PNG media_image28.png 223 248 media_image28.png Greyscale PNG media_image29.png 220 222 media_image29.png Greyscale PNG media_image30.png 219 201 media_image30.png Greyscale PNG media_image31.png 253 260 media_image31.png Greyscale PNG media_image32.png 275 350 media_image32.png Greyscale PNG media_image33.png 286 229 media_image33.png Greyscale PNG media_image34.png 296 225 media_image34.png Greyscale PNG media_image35.png 305 217 media_image35.png Greyscale PNG media_image36.png 301 220 media_image36.png Greyscale PNG media_image37.png 228 353 media_image37.png Greyscale or PNG media_image38.png 236 357 media_image38.png Greyscale .
