Office Action

§112
DETAILED ACTION Claims 1-27 are pending. 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 . Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Information Disclosure Statement The information disclosure statements (IDSs) submitted on 04/24/2024 and 07/28/2025 are acknowledged. The submissions are in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. Nucleotide and/or Amino Acid Sequence Disclosures REQUIREMENTS FOR PATENT APPLICATIONS CONTAINING NUCLEOTIDE AND/OR AMINO ACID SEQUENCE DISCLOSURES Items 1) and 2) provide general guidance related to requirements for sequence disclosures. 37 CFR 1.821(c) requires that patent applications which contain disclosures of nucleotide and/or amino acid sequences that fall within the definitions of 37 CFR 1.821(a) must contain a "Sequence Listing," as a separate part of the disclosure, which presents the nucleotide and/or amino acid sequences and associated information using the symbols and format in accordance with the requirements of 37 CFR 1.821 - 1.825. This "Sequence Listing" part of the disclosure may be submitted: In accordance with 37 CFR 1.821(c)(1) via the USPTO patent electronic filing system (see Section I.1 of the Legal Framework for Patent Electronic System (https://www.uspto.gov/PatentLegalFramework), hereinafter "Legal Framework") as an ASCII text file, together with an incorporation-by-reference of the material in the ASCII text file in a separate paragraph of the specification as required by 37 CFR 1.823(b)(1) identifying: the name of the ASCII text file; ii) the date of creation; and iii) the size of the ASCII text file in bytes; In accordance with 37 CFR 1.821(c)(1) on read-only optical disc(s) as permitted by 37 CFR 1.52(e)(1)(ii), labeled according to 37 CFR 1.52(e)(5), with an incorporation-by-reference of the material in the ASCII text file according to 37 CFR 1.52(e)(8) and 37 CFR 1.823(b)(1) in a separate paragraph of the specification identifying: the name of the ASCII text file; the date of creation; and the size of the ASCII text file in bytes; In accordance with 37 CFR 1.821(c)(2) via the USPTO patent electronic filing system as a PDF file (not recommended); or In accordance with 37 CFR 1.821(c)(3) on physical sheets of paper (not recommended). When a “Sequence Listing” has been submitted as a PDF file as in 1(c) above (37 CFR 1.821(c)(2)) or on physical sheets of paper as in 1(d) above (37 CFR 1.821(c)(3)), 37 CFR 1.821(e)(1) requires a computer readable form (CRF) of the “Sequence Listing” in accordance with the requirements of 37 CFR 1.824. If the "Sequence Listing" required by 37 CFR 1.821(c) is filed via the USPTO patent electronic filing system as a PDF, then 37 CFR 1.821(e)(1)(ii) or 1.821(e)(2)(ii) requires submission of a statement that the "Sequence Listing" content of the PDF copy and the CRF copy (the ASCII text file copy) are identical. If the "Sequence Listing" required by 37 CFR 1.821(c) is filed on paper or read-only optical disc, then 37 CFR 1.821(e)(1)(ii) or 1.821(e)(2)(ii) requires submission of a statement that the "Sequence Listing" content of the paper or read-only optical disc copy and the CRF are identical. Specific deficiencies and the required response to this Office Action are as follows: Specific deficiency – Nucleotide and/or amino acid sequences appearing in the drawings (e.g., see Figures 4, 22, 28) are not identified by sequence identifiers in accordance with 37 CFR 1.821(d). Sequence identifiers for nucleotide and/or amino acid sequences must appear either in the drawings or in the Brief Description of the Drawings. Required response – Applicant must provide: Replacement and annotated drawings in accordance with 37 CFR 1.121(d) inserting the required sequence identifiers; AND/OR A substitute specification in compliance with 37 CFR 1.52, 1.121(b)(3) and 1.125 inserting the required sequence identifiers into the Brief Description of the Drawings, consisting of: A copy of the previously-submitted specification, with deletions shown with strikethrough or brackets and insertions shown with underlining (marked-up version); A copy of the amended specification without markings (clean version); and A statement that the substitute specification contains no new matter. Specific deficiency – Nucleotide and/or amino acid sequences appearing in the specification are not identified by sequence identifiers in accordance with 37 CFR 1.821(d). Required response – Applicant must provide: A substitute specification in compliance with 37 CFR 1.52, 1.121(b)(3) and 1.125 inserting the required sequence identifiers, consisting of: A copy of the previously-submitted specification, with deletions shown with strikethrough or brackets and insertions shown with underlining (marked-up version); A copy of the amended specification without markings (clean version); and A statement that the substitute specification contains no new matter. Specification The use of the term NUPACK, which is a trade name or a mark used in commerce, has been noted in this application. The term should be accompanied by the generic terminology; furthermore the term should be capitalized wherever it appears or, where appropriate, include a proper symbol indicating use in commerce such as ™, SM , or ® following the term. Although the use of trade names and marks used in commerce (i.e., trademarks, service marks, certification marks, and collective marks) are permissible in patent applications, the proprietary nature of the marks should be respected and every effort made to prevent their use in any manner which might adversely affect their validity as commercial marks. The disclosure is also objected to because it contains an embedded hyperlink and/or other form of browser-executable code. Applicant is required to delete the embedded hyperlink and/or other form of browser-executable code; references to websites should be limited to the top-level domain name without any prefix such as http:// or other browser-executable code. See MPEP § 608.01. Claim Objections Claims 5-26 are objected to under 37 CFR 1.75(c) as being in improper form because a multiple dependent claim should refer to other claims in the alternative only, and cannot depend from any other multiple dependent claim. See MPEP § 608.01(n). Accordingly, the claims have not been further treated on the merits. Claim 15 is objected to because of the following informalities: there is a gap of several spaces between the last character of the claim (i.e., after “31”) and the period that ends the sentence. Appropriate correction is required. 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 1-27 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. 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 1 recites the broad recitation “between 150 and 800 nucleotides”, and the claim also recites “preferably between 200 and 600 nucleotides” which is the narrower statement of the range/limitation. Claim 1 also recites the broad recitation “between 7 and 100 nucleotides”, and the claim also recites “preferably between 10 and 50 nucleotides” which is the narrower statement of the range/limitation. Claim 1 also recites the broad recitation “at least 2 nucleotides”, and the claim also recites “preferably 3 nucleotides or more” which is the narrower statement of the range/limitation. Claim 1 also recites the broad recitation “at least 5 nucleotides”, and the claim also recites “preferably 10 nucleotides or more” which is the narrower statement of the range/limitation. Claims 2-26 are included as they are dependent claims. Additionally, claims 3-4 recite the broad recitation “at least 2 nucleotides”, and the claim also recites “preferably 3 nucleotides or more” which is the narrower statement of the range/limitation. Claim 12 recites the broad recitation “Coronavirus”, and the claim also recites “preferably from (SARS-CoV-2)” which is the narrower statement of the range/limitation. Claim 22 recites the broad recitation “comprises”, and the claim also recites “preferably, consists of” which is the narrower statement of the range/limitation. Claim 26 recites the broad recitation “SARS and/or MERS”, and the claim also recites “preferably SARS-CoV-2” which is the narrower statement of the range/limitation. Claims 26 and 27 include the phrase "such as", which renders the claims indefinite because it is unclear whether the limitations following the phrase are part of the claimed invention. See MPEP § 2173.05(d). Claim 27 also recites the broad recitation “at least 2 nucleotides”, and the claim also recites “preferably 3 nucleotides or more” which is the narrower statement of the range/limitation. Claim 27 also recites the broad recitation “at least 5 nucleotides”, and the claim also recites “preferably 10 nucleotides or more” which is the narrower statement of the range/limitation. Claim 27 also recites the broad recitation “between 7 and 100 nucleotides”, and the claim also recites “preferably between 10 and 50 nucleotides” which is the narrower statement of the range/limitation. Claim 27 also recites the broad recitation “between 150 and 800 nucleotides”, and the claim also recites “preferably between 200 and 600 nucleotides” 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. Additionally, claim 27 is indefinite because it contains the trademark/trade name NUPACK. Where a trademark or trade name is used in a claim as a limitation to identify or describe a particular material or product, the claim does not comply with the requirements of 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph. See Ex parte Simpson, 218 USPQ 1020 (Bd. App. 1982). The claim scope is uncertain since the trademark or trade name cannot be used properly to identify any particular material or product. A trademark or trade name is used to identify a source of goods, and not the goods themselves. Thus, a trademark or trade name does not identify or describe the goods associated with the trademark or trade name. In the present case, the trademark/trade name is used to identify/describe an RNA folding tool and, accordingly, the identification/description is indefinite. Additionally, claim 27 is indefinite because it includes Roman numerals “iii.” and “iv.” without first reciting Roman numerals “i.”, “ii.”, and “iii.”, and also including letters “d)”, “e)’, and “f)” without first reciting letters “a)”, “b)”, and “c)”, thus rendering the claim indefinite as it is unclear if the claim is missing parts “i.”, “ii.”, “iii.”, “a)”, “b)”, and “c)”. Appropriate correction is required. Relevant Prior Art The prior art does not teach the claimed artificial circular RNA. WO 2013/162350 (of record, IDS citation) is considered the closest prior art as it teaches artificial circular RNAs that inhibit viral replication by acting as triple helix forming oligonucleotides (TFOs) that target genomic sequences of single stranded RNA viruses.
