Office Action

§102 §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 . Applicant’s election without traverse of Group I claims 1-11 in the reply filed on 5/4/26 is acknowledged. 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. Applicant must provide a proper abstract with the next response. 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 1-11 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. When “x” of claim is zero or one, a “polymer” does not result. The electron acceptor group RA must be a divalent entity according to claim 1’s formula (I). However, the depicted structures of claims 2 and 3 are not divalent entities. These are complete stand alone compounds. The electron donor group RB must be a monovalent entity according to claim 1’s formula (I). However, the depicted structures of claims 4 and 5 are not monovalent entities. These are complete stand alone compounds. 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. Claims 1-11 rejected under 35 U.S.C. 102(a)(1) as being anticipated by Pu 2021/0087463. Pu exemplifies (#7) produces PPV-PEGL polymer. This PPV-PEGL is both fluorescent and degradable (paragraph 252) which meets applicant’s “depolymerizable and luminescent”. Applicant’s claims require no particular structure when “x” is zero. The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. CN111471036 discloses a diamine monomer for making polymers that has applicant’s >carbazole - RA- RB . However, the reference’s dianhydrides to be reacted with this diamine do not provide the specific RC units required by applicant. The Liu article in Nature Materials teaches similar polymers to applicant, but lack the second RC in applicant’s repeating unit as shown by: PNG media_image1.png 250 803 media_image1.png Greyscale Applicant requires adjacent -RC- when “x” is two or more as shown by: PNG media_image2.png 195 650 media_image2.png Greyscale Additionally, the Liu article does not suggest the RE (eg ester, amide or imide) of applicant’s claims. Any inquiry concerning this communication or earlier communications from the examiner should be directed to DAVID J BUTTNER whose telephone number is (571)272-1084. The examiner can normally be reached M-F 9-3pm. Examiner interviews are available via telephone, in-person, and video conferencing using a USPTO supplied web-based collaboration tool. To schedule an interview, applicant is encouraged to use the USPTO Automated Interview Request (AIR) at http://www.uspto.gov/interviewpractice.
