Office Action

§101 §102
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 . DETAILED ACTION This Non-Final Office Action is responsive to the communication received 11/24/2025. Election/Restrictions Applicant’s election without traverse in the Reply filed on 11/24/2025 of Group I, Claim(s) 1-7 is acknowledged. Applicant has elected without traverse in the Reply filed on 11/24/2025 the following species: A. the spike protein amino acid sequence is histidine at position 675 (SEQ ID 3) (claim 7). The Restriction/Election Requirements are deemed proper and are made FINAL. Claims 1-7 and 12-24 are pending. Claims 12-24 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected invention, there being no allowable generic or linking claim. Election was made without traverse in the Reply filed on 11/24/2025. Claims 1-7 are under examination in this Office Action. Claim Rejections - 35 USC § 101 35 U.S.C. 101 reads as follows: Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title. Claims 1-7 are rejected under 35 U.S.C. 101 because the claimed invention is directed to nonstatutory subject matter. The claim(s) does/do not fall within at least one of the four categories of patent eligible subject matter because the claimed invention is directed to a judicial exception, an abstract idea, without significantly more. Claims 2-7 depend directly or indirectly from claim 1. The claims 1 and 2 limitations directed to an abstract idea involving mental processes are a method of identifying compounds useful in treating or preventing infection by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the method comprising: screening at least one candidate compound for an ability to inhibit cleavage of a SARS-CoV-2 spike protein by a human protease at one or more target site; further comprising: determining, for the at least one candidate compound, a level of inhibition of host cell peptide cleavage. The claim(s) does/do not include additional elements that are sufficient to amount to significantly more than the judicial exception because the claim does not recite any additional elements. 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 1-7 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Meng et al. (02/16/2020) bioRxiv doi 10.1101/2020.02.08.926006 pages 1 to 36 cited in the 9/21/2022 IDS (hereinafter referred to as "Meng"). With regards to claims 1-7, Meng teaches: a) as in claims 1-7, a method of identifying compounds useful in treating or preventing infection by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the method comprising: screening at least one candidate compound for an ability to inhibit cleavage of a SARS-CoV-2 spike protein by a human protease at one or more target site; further comprising: determining, for the at least one candidate compound, a level of inhibition of host cell peptide cleavage; wherein the one or more target site is threonine at position 768 and glycine at position 769 of SEQ ID 1; wherein the at least one candidate compound includes a plurality of compounds; wherein screening includes screening the plurality of compounds in an assay; wherein the ability to inhibit cleavage includes binding of the at least one candidate compound with the human protease; further comprising: determining whether the spike protein amino acid sequence includes one or more mutation from a wildtype sequence (SEQ ID 1), the one or more mutation being histidine at position 675 (SEQ ID 3) (see entire document especially pages 6 to 14). Thus, Meng anticipates the present claims. Conclusion No claim is allowed.
