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 . Claim Objections Claims 7 and 23 are objected to because of the following informalities: some of the subscript designations, as well as single bond vs double bonds are not clearly distinguishable. Appropriate correction is required. Abstract Applicant is reminded of the proper content of an abstract of the disclosure. In chemical patent abstracts for compounds or compositions, the general nature of the compound or composition should be given as well as its use, e.g., “The compounds are of the class of alkyl benzene sulfonyl ureas, useful as oral anti-diabetics.” Exemplification of a species could be illustrative of members of the class. For processes, the type of reaction, reagents and process conditions should be stated, generally illustrated by a single example unless variations are necessary. The abstract of the disclosure is objected to because the abstract does not reflect the inventive compound of formula 1 containing a group of the present formula 2, characterized in that said group of the present formula 2 comprises at least one substituted or unsubstituted cycloalkyl group having 5 to 30 carbon atoms. A corrected abstract of the disclosure is required and must be presented on a separate sheet, apart from any other text. See MPEP § 608.01(b). 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 1-23 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. Claims 1 and 17 are rejected as being vague and indefinite when they each recite formula 2 PNG media_image1.png 354 617 media_image1.png Greyscale (emphasis added); the scope of the protection sought by “*” is not clear. Claims 1 and 17 are rejected as being vague and indefinite when they each recite “when R14 to R19 are a crosslinked cycloalkyl group, each of a plurality of rings in the crosslinked cycloalkyl group has 5 to 10 ring-forming carbon atoms” (emphasis added); the scope of the protection sought is not clear, as there appears to be insufficient antecedent basis in the claims for R14 to R19 being a crosslinked cycloalkyl group. Claims 1 and 17 each fail to particularly point out and distinctly claim the polycyclic compound of formula 1. Claims 1 and 17 are rejected as being vague and indefinite when they each recite “Formula 1 comprises a structure in which one or more hydrogens are substituted with deuterium” (emphasis added); the scope of the protection sought is not clear. The antecedent basis for the “one or more hydrogens” is not clear since each of the substituents Ra to Rd , R1 to R12, L, Re to Ri , and R13 to R20 therein Formula I may be and/or contain hydrogen. Claims 1 and 17 each fail to particularly point out and distinctly claim the polycyclic compound of formula 1. Claims 2 and 18 are rejected as being vague and indefinite when they each recite the formulae 2-1a and 2-1b PNG media_image2.png 352 670 media_image2.png Greyscale PNG media_image3.png 456 659 media_image3.png Greyscale (emphasis added); the scope of the protection sought by “*” is not clear. Claims 3 and 19 are rejected as being vague and indefinite when they each recite the formulae 2-2a, and 2-2c through 2-2g: PNG media_image4.png 433 675 media_image4.png Greyscale PNG media_image5.png 410 671 media_image5.png Greyscale PNG media_image6.png 415 682 media_image6.png Greyscale PNG media_image7.png 405 682 media_image7.png Greyscale PNG media_image8.png 446 671 media_image8.png Greyscale PNG media_image9.png 448 653 media_image9.png Greyscale (emphasis added); the scope of the protection sought by “*” is not clear. Claims 3 and 19 are rejected as being vague and indefinite when they each recite the formula 2-2d: PNG media_image10.png 426 693 media_image10.png Greyscale (emphasis added); the scope of the protection sought is not clear as there is neither antecedent basis for, or a definition for the substituent P20 therein formula 2-2d. Claims 3 and 19 each fail to particularly point out and distinctly claim the group of formula 2 contained in the polycyclic compound of formula 1. Claims 4 and 20 are rejected as being vague and indefinite when they each recite the formulae 2-3a through 2-3e: PNG media_image11.png 314 603 media_image11.png Greyscale PNG media_image12.png 309 601 media_image12.png Greyscale PNG media_image13.png 354 579 media_image13.png Greyscale PNG media_image14.png 294 640 media_image14.png Greyscale PNG media_image15.png 306 614 media_image15.png Greyscale (emphasis added); the scope of the protection sought by “*” is not clear. Claims 4 and 20 are rejected as being vague and indefinite when they each recite “Formulas 2-3a to 2-3e each comprise a structure in which one or more hydrogens are substituted with deuterium” (emphasis added); the scope of the protection sought is not clear. The antecedent basis for the “one or more hydrogens” is not clear since each of the substituents L, Re to Ri , R13 to R16 , and R18 to R20 therein Formula I may be and/or contain hydrogen. Claims 4 and 20 each fail to particularly point out and distinctly claim the group of formula 2 contained in the polycyclic compound of formula 1. Claims 5 and 21 are rejected as being vague and indefinite when they each recite “wherein at least one selected from among R14 to R19 is represented by any one selected from among Formulas A1 to A5” (emphasis added); the scope of the protection sought by “any one (blank) selected from among” is not clear. Claims 5 and 21 each fail to particularly point out and distinctly claim the group of formula 2 contained in the polycyclic compound of formula 1, i.e., wherein at least one of the substituents R14 to R19 is represented one of Formulae A1 to A5. Claims 5 and 21 are rejected as being vague and indefinite when they each recite the groups represented by A1 through A5: PNG media_image16.png 225 803 media_image16.png Greyscale (emphasis added); the scope of the protection sought by “ PNG media_image17.png 49 52 media_image17.png Greyscale ” is not clear. Claim 8 is rejected as being vague and indefinite when it recites “wherein the at least one functional layer further comprise at least one selected from among a second compound represented by Formula HT and a third compound represented by Formula ET” (emphasis added); the scope of the protection sought by “any one (blank) selected from among” is not clear. Claim 8 fails to particularly point out and distinctly claim the contents of the functional layer contained in the claimed light emitting element, i.e., wherein said functional further comprises a compound represented by Formula HT and or a compound represented by Formula ET. Claim 10 is rejected as being vague and indefinite when it recites “the first compound; and at least one selected from among the second compound and the third compound” (emphasis added); the scope of the protection sought by “at least one (blank) selected from among” is not clear. Claim 10 fails to particularly point out and distinctly claim the contents of the emission layer contained in the claimed light emitting element. Claim 11 is rejected as being vague and indefinite when it recites “wherein the emission layer is to emit delayed fluorescence” (emphasis added); the scope of the protection sought by “is to emit” is not clear. Claim 11 fails to particularly point out and distinctly claim the contents of the emission layer contained in the claimed light emitting element. Claim 12 is rejected as being vague and indefinite when it recites “wherein the emission layer is to emit blue light” (emphasis added); the scope of the protection sought by “is to emit” is not clear. Claim 12 fails to particularly point out and distinctly claim the contents of the emission layer contained in the claimed light emitting element. Prior Art The following prior art made of record and not relied upon is considered pertinent to applicant’s disclosure: U.S. Patent Application Publication No. 2024/0268231, which is the pre-grant publication corresponding to the present application; Chinese Patent No. CN 121108165 A, which is pertinent to applicant’s polycyclic compound of the present formula 1 containing a group of the present formula 2, characterized in that said group of the present formula 2 comprises at least one substituted or unsubstituted cycloalkyl group having 5 to 30 carbon atoms; and Chinese Patent No. CN 114478592, which is pertinent to applicant’s polycyclic compound of the present formula 1 characterized by containing a group of the present formula 2, but which is missing the at least one substituted or unsubstituted cycloalkyl group having 5 to 30 carbon atoms on the group of the present formula 2.
