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 This application 18/037,598 filed on 05/18/2023 is a national phase application under 35 U.S.C. § 371 that claims priority to International Application No. PCT/CN2021/131951 field on 11/19/2021, and claims priority of foreign application CN 202011302953.5 filed on 11/19/2020. A certified copy of foreign application CN 202011302953.5 filed on 11/19/2020 has been submitted of the record by Applicants on 05/18/2023. Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. No English translation of foreign application CN 202011302953.5 filed on 11/19/2020 has been provided. The priority date of claim set filed on 01/05/2026 is determined to be 11/19/2021, the filing date of PCT/CN2021/131951. Should applicant desire to obtain the benefit of foreign priority under 35 U.S.C. 119(a)- (d) prior to declaration of an interference, a certified English translation of the foreign application must be submitted in reply to this action. 37 CFR 41.154(b) and 41.202(e). Failure to provide a certified translation may result in no benefit being accorded for the non-English application. Restriction/Election Applicant’s election without traverse of Group I invention, claims 1-2, in the reply filed on 01/14/2026 is acknowledged. Regarding Species election (I) of siRNA, Applicants elected the sense strand has a nucleotide sequence of 5'- CUGAGUCUUGGAAGUGGAUCCUUTT-3' (SEQ ID NO.5), and the antisense strand has a nucleotide sequence of 5'- AAGGAUCCACUUCCAAGACUCAGTT-3' (SEQ ID NO.6); Regarding Species election (II) of siRNA modification, Applicants elected the 2'-O-ribose methylation Claims 1-11 are pending. Claims 3-11 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected invention, there being no allowable generic or linking claim.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 01/14/2026. Claims 1-2 are currently under examination. 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 1-2 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. Amended claim 1 filed on 01/14/2026 reads as follows: A small interfering RNA that inhibits the expression of target gene NOX1, consisting of a sense strand and an antisense strand reversely complementary thereto, wherein sequences of the sense strand and the antisense strand are (3) sequences of No. 3 small interfering RNA the sense strand has a nucleotide sequence of 5'- CUGAGUCUUGGAAGUGGAUCCUUTT-3' (SEQ ID NO.5), the antisense strand has a nucleotide sequence of 5'- AAGGAUCCACUUCCAAGACUCAGTT-3' (SEQ ID NO.6); wherein, the antisense strand is reversely complementary to a fragment of the target gene.” The limitation “(3) sequences of No. 3 small interfering RNA” along with limitations “the sense strand has a nucleotide sequence of 5'- CUGAGUCUUGGAAGUGGAUCCUUTT-3' (SEQ ID NO.5), the antisense strand has a nucleotide sequence of 5'- AAGGAUCCACUUCCAAGACUCAGTT-3'(SEQ ID NO.6)” is unclear regarding whether SEQ ID NO: 3 of instant application is encompassed by the limitation “sequences of No. 3”. Additionally, it is unclear whether “5'- CUGAGUCUUGGAAGUGGAUCCUUTT-3'” is SEQ ID NO. 5 (i.e. a DNA molecule with both nucleotide T and nucleotide U) and whether “5'- AAGGAUCCACUUCCAAGACUCAGTT-3'” is SEQ ID NO. 6 (i.e. a DNA molecule with both nucleotide T and nucleotide U). <210> SEQ ID NO 5 <211> LENGTH: 25 <212> TYPE: DNA <213> ORGANISM: Artificial Sequence <220> FEATURE: <223> OTHER INFORMATION: sense strand <400> SEQUENCE:5 cugagucuug gaaguggauc cuutt 25 <210> SEQ ID NO 6 <211> LENGTH: 25 <212> TYPE: DNA <213> ORGANISM: Artificial Sequence <220> FEATURE: <223> OTHER INFORMATION: antisense strand <400> SEQUENCE: 6 aaggauccac uuccaagacu cagtt 25 Claim 2 depends from claim 1. Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claims 1 and 2 are rejected under 35 U.S.C. 103 as being unpatentable over Goyal et al. (2004) (Goyal et al., Upregulation of NAD(P)H oxidase 1 in hypoxia activates hypoxia-inducible factor 1 via increase in reactive oxygen species, Free Radic. Biol. Med. 36 (10), 1279-1288 (2004)) in view of GenBank: AK313678.1 (2008), Juhasz et al. (US 2008/0039420 A1, which is the publication of US application No. 11/785, 419), Lisowiec-Wachnicka et al.

Claims 1 is directed to “A small interfering RNA that inhibits the expression of target gene NOX1, consisting of a sense strand and an antisense strand reversely complementary thereto, wherein sequences of the sense strand and the antisense strand are (3) sequences of No. 3 small interfering RNA, the sense strand has a nucleotide sequence of 5'- CUGAGUCUUGGAAGUGGAUCCUUTT-3'(SEQ ID NO. 5), the antisense strand has a nucleotide sequence of 5'- AAGGAUCCACUUCCAAGACUCAGTT-3'(SEQ ID NO. 6); wherein, the antisense strand is reversely complementary to a fragment of the target gene.” Claim 2 is directed to “The small interfering RNA according to claim 1, wherein the sense strand and the antisense strand are optionally modified with 2'-O-ribose modification on the first 21 nucleotides from the 5' end, and the 2'-O-ribose modification is 2'-O-ribose methylation modification”. Claim interpretations: Regarding claim 2, the optional 2'-O-ribose methylation modification encompass the absence of 2'-O-ribose methylation. Goyal et al. (2004) teaches “Upregulation of NAD(P)H oxidase 1 in hypoxia activates hypoxia-inducible factor 1 via increase in reactive oxygen species” (See Title). SEQ ID NO:5 (sense, nucleotides 1-23) and SEQ ID NO:6 (antisense, nucleotides 1-23) of instant application are nucleotide sequences 800-822 of Homo sapiens mRNA for nox1 NAD(P)H-oxidase subunit (NOX1 gene) (See alignments copied below with the Queries (Qy) being SEQID NO: 5 and SEQ ID NO: 6 of instant application).

(US 2008/0039420). The combined teachings of Goyal et al. (2004), GenBank: AK313678.1 (2008), and Juhasz et al. (US 2008/0039420 A1) do not explicitly teach addition of TT di-nucleotides that are added in 5'- CUGAGUCUUGGAAGUGGAUCCUUTT-3' (SEQ ID NO. 5) and in 5'- AAGGAUCCACUUCCAAGACUCAGTT-3' (SEQ ID NO. 6). Lisowiec-Wachnicka et al. (2019) teaches “Contribution of 3′ T and 3′TT overhangs to the thermodynamic stability of model siRNA duplexes” See Title). Lisowiec-Wachnicka et al. (2019) teaches that “Herein, we report comprehensive thermodynamic studies on 36 RNA/DNA duplexes designed as siRNA mimics to determine the energetic contribution of 3′T and 3′TT dangling ends. The thermodynamic effect induced by the presence of 3′T overhangs on the stability of RNA duplexes ranges from −0.28 to −0.92 kcal/mol and strongly depends on the type and orientation of the adjacent base pair. Further extension of the 3′-dangling end length, by a second T residue, results in additional stabilization of 0.14 to 0.21 kcal/mol. The results revealed that the thermodynamic contribution of 3′-dangling T and TT on RNA duplexes differs from the influence of 3′-dangling U and UU on RNA duplexes and 3′-dangling T and TT on DNA duplexes. This data suggests that using the contribution of 3′-dangling T values for RNA duplexes, instead of 3′-dangling T values for DNA duplexes or 3′- dangling U values for RNA duplexes, would improve the prediction of the stability of siRNA duplexes (See Abstract).” PNG media_image1.png 430 790 media_image1.png Greyscale Furthermore, Tafer (2014) teaches “Bioinformatics of siRNA design” (See Title), and “Sequence-Based siRNA Design” (See pages 479-484, Fig. 2 copied below). PNG media_image2.png 410 876 media_image2.png Greyscale Fig. 2 Top: Weblogo representation of the highest scoring siRNA target sequence for the algorithm from Reynolds, Hsieh, Takasaki, Dsir, Amarzguioui, Katoh, and iScore. The sequence asymmetry is clearly seen, as well as the presence of a T at position 10. Bottom: Heatmap representation of the sum of the normalized coefficients of the models from Reynolds, Hsieh, Takasaki, Dsir, Amarzguioui, Katoh, and iScore for each nucleotide and position along the siRNA target sequence. Dark squares represent preferred nucleotide/position combination while light ones stand for unfavorable nucleotide/position. Here also the sequence asymmetry is clearly seen, with A/T being highly preferred at the target 3_ end, while G/C being overrepresented at the target 5’ end. It would have been prima facie obvious for a skilled artisan to incorporate the disclosure of “Contribution of 3′ T and 3′ TT overhangs to the thermodynamic stability of model siRNA duplexes” taught by Lisowiec-Wachnicka et al. (2019) and “Sequence-Based siRNA Design” taught by Tafer (2014) into the combined teachings of modulating gene expression of the NOX1 gene in lung pathology (Goyal et al.) and colon cancer cells (Juhasz et al.) in light of known cDNA, mRNA, and protein sequences of human NOX1 taught by Goyal et al. (2004) and GenBank: AK313678.1 (2008), along with the teachings of Juhasz et al. (US 2008/0039420 A1) regarding “compositions and methods for gene-specific inhibition of gene expression by short interfering ribonucleic acid (siRNA) effector molecules” to arrive at instant claims 1 and 2 because cDNA, mRNA, and protein sequences of human NOX1 are clearly known to a skilled artisan, and siRNA design and application of siRNA in inhibition of gene inhibition are well established in the field of siRNA medicated inhibition of gene expression. A skilled artisan would be motivated to combine the teachings Lisowiec-Wachnicka et al. (2019) and “Sequence-Based siRNA Design” taught by Tafer (2014) into the combined teachings of Goyal et al. (2004), GenBank: AK313678.1 (2008), and Juhasz et al. (US 2008) with reasonable expectation of success because (i) the three references Lisowiec-Wachnicka et al. (2019), Tafer (2014), and Juhasz et al. (2008) are analogous arts in the same field of endeavor pertaining to compositions for gene-specific inhibition of gene expression by short interfering ribonucleic acid (siRNA) effector molecules, (ii) the teachings of SEQ ID NO. 7 by Juhasz et al. (2008), which includes addition of TT dinucleotide at 3’ end, correspond to SEQ ID NO: 1 (sense) and SEQ ID NO: 2 (antisense) of instant application, and (iii) cDNA, mRNA, and protein sequences of human NOX1 taught by Goyal et al. (2004) and GenBank: AK313678.1 (2008). Claim 2 is rejected under 35 U.S.C. 103 as being unpatentable over Goyal et al. (2004) (Goyal et al., Upregulation of NAD(P)H oxidase 1 in hypoxia activates hypoxia-inducible factor 1 via increase in reactive oxygen species, Free Radic. Biol. Med. 36 (10), 1279-1288 (2004)) in view of GenBank: AK313678.1 (2008), Juhasz et al. (US 2008/0039420 A1, which is the publication of US application No. 11/785, 419), Lisowiec-Wachnicka et al. (2019) (Lisowiec-Wachnicka et al., Contribution of 3′ T and 3′TT overhangs to the thermodynamic stability of model siRNA duplexes, Biophys Chem., 2019 Mar:246:35-39. doi: 10.1016/j.bpc.2018.12.006. Epub 2019 Jan 7.), and Tafer (2014) (Tafer, Bioinformatics of siRNA design, Methods Mol Biol. 2014;1097:477-90. doi: 10.1007/978-1-62703-709-9_22) as applied to claim 1 above, and further in view of Yokata et al. (US 2010/0234282 A1). Claim 2 is directed to “The small interfering RNA according to claim 1, wherein the sense strand and the antisense strand are optionally modified with 2'-O-ribose modification on the first 21 nucleotides from the 5' end, and the 2'-O-ribose modification is 2'-O-ribose methylation modification”. Claim interpretations: Regarding claim 2, the optional 2'-O-ribose methylation modification encompass the presence of 2'-O-ribose methylation. The teachings of Goyal et al. (2004), GenBank: AK313678.1 (2008), Juhasz et al. (US 2008/0039420), Lisowiec-Wachnicka et al. (2019) and Tafer (2014) have been documented above in the rejection of claim 1. The combined teachings of Goyal et al. (2004), GenBank: AK313678.1 (2008), Juhasz et al. (US 2008/0039420), Lisowiec-Wachnicka et al. (2019) and Tafer (2014) do not explicitly teach the optional 2'-O-ribose methylation modification of nucleotide Yokata et al. (US 2010/0234282 A1) teaches “System for delivering nucleic acid for suppressing target gene expression (See Title); and “The object of present invention is to provide a system that can deliver in vivo nucleic acids such as an siRNA for suppressing a target gene expression in vivo more safely and efficiently, and to provide an expression-suppressing agent and a pharmaceutical composition utilizing the system. An introduction substance into chylomiclon, particularly nucleic acids to which an alpha-tocopherol is bound for suppressing a target gene expression, can be delivered more safely and efficiently into hepatic cells in vivo by administering the nucleic aids under the condition where the production of chylomicron is induced in the body. Alternatively, alpha-tocopherol-bound nucleic acids are mixed with extracted chylomiclon, and then they are administered. Consequently, a target gene expression is suppressed, thereby a disease caused by an elevated expression of the target gene can be treated more safely and efficiently (See Abstract). Yokata et al. (US 2010/0234282 A1) further teaches “Subsequently, these nucleotide sequences were modified for an improved stability to in vivo RNases. More specifically, the nucleotides of nucleotide numbers 2, 5, 11, 15, 21, 24, and 25 of the siRNA sense strand (SEQ ID NO: 1) and the nucleotides of nucleotide numbers of 1, 2, 5, 12, 14, 21, 24, 25, and 26 of the antisense strand (SEQ ID NO: 2) were subjected to 2’-O ribose methylation; the skeletal bond of the nucleotide of nucleotide number 26 of the sense strand (SEQ ID NO: 1) was subjected to thiophosphorylation; and further, the nucleotides of nucleotide numbers 3, 4, 6, 27, and 28 of the antisense strand (SEQ ID NO: 2) were subjected to 2'-ribose methylation as well as thiophosphorylation of their skeletal bond” (See [0094]). It would have been prima facie obvious for a skilled artisan to incorporate the disclosure of “2’-O ribose methylation” to various positions of the nucleotides of siRNA molecules taught by Yokata et al. (US 2010/0234282 A1) into the combined teachings of Goyal et al. (2004), GenBank: AK313678.1 (2008), Juhasz et al. (US 2008/0039420), Lisowiec-Wachnicka et al. (2019) and Tafer (2014) to “provide a system that can deliver in vivo nucleic acids such as an siRNA for suppressing a target gene expression in vivo more safely and efficiently”. A skilled artisan would be motivated to combine the teachings of Yokata et al. (US 2010/0234282 A1) with the collective teachings of Goyal et al. (2004), GenBank: AK313678.1 (2008), Juhasz et al. (US 2008/0039420), Lisowiec-Wachnicka et al. (2019) and Tafer (2014) with reasonable expectation of success because (i) the three references Lisowiec-Wachnicka et al. (2019), Tafer (2014), and Juhasz et al. (2008) are analogous arts in the same field of endeavor pertaining to compositions for gene-specific inhibition of gene expression by short interfering ribonucleic acid (siRNA) effector molecules, (ii) the teachings of SEQ ID NO. 7 by Juhasz et al.
