Office Action

§103
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 The present application claims priority to the application, IN2022/11038517, with the effective filing date of 5 July 2022. The Examiner notes Applicant’s remarks confirming that the priority application, IN2022/11038517, is a certified copy. Claim Status This Office Action is in response to Applicant’s Amendment filed, 5 May 2026. Claims 11-15 were previously canceled and claims 3, 8, and 16-25 were previously withdrawn. Claims 1-2, 4-7, and 9-10 are pending. Information Disclosure Statement The Information Disclosure Statement filed on 5 May 2026 and the references cited therein have been considered, unless indicated otherwise. The reference, Miloh (AASLD abstract), wherein a copy was provided but is illegible, is lined through. Rejections New/Maintained Claim Rejections – 35 U.S.C. § 103 1. (Maintained) Claims 1-2, 4-7, and 9-10 were rejected under 35 U.S.C. 103 as being unpatentable over Jung (U.S. Patent No. 9,890,129, issued 13 Feb 2019; of record, see PTO-892 mailed 5 Feb 2026) in view of Surur (Arch. Pharm. Chem. Life Sci., 2019, 352(e1800248), 1-11; of record, see PTO-892 mailed 5 Feb 2026). Applicant's arguments filed 5 May 2026 have been fully considered but they are not persuasive. Applicant argues that neither Jung nor Surur, taken alone or together, provides teachings or suggestions for making the specific modifications to the cited compound of Jung. Applicant further argues a person of ordinary skill in the art would not have been motivated to modify the cited compound of Jung in the manner of the present invention and especially not with a reasonable expectation of success. Additionally, Applicant argues that the Office solely based the rejection on alleged structural similarity of bioisostere equivalents of nitrogen and sulfur. In response to Applicant's arguments against the references individually, one cannot show nonobviousness by attacking references individually where the rejections are based on combinations of references. See In re Keller, 642 F.2d 413, 208 USPQ 871 (CCPA 1981); In re Merck & Co., 800 F.2d 1091, 231 USPQ 375 (Fed. Cir. 1986). In response to Applicant’s argument that there is no teaching, suggestion, or motivation to combine Jung and Surur, the Examiner recognizes that obviousness may be established by combining or modifying the teachings of the prior art to produce the claimed invention where there is some teaching, suggestion, or motivation to do so found either in the references themselves or in the knowledge generally available to one of ordinary skill in the art. See In re Fine, 837 F.2d 1071, 5 USPQ2d 1596 (Fed. Cir. 1988), In re Jones, 958 F.2d 347, 21 USPQ2d 1941 (Fed. Cir. 1992), and KSR International Co. v. Teleflex, Inc., 550 U.S. 398, 82 USPQ2d 1385 (2007). In this case, one of ordinary skill in the art would have been motivated to make such a selection, with a reasonable expectation of success, because: -Jung teaches compounds and compositions of aminoalkylbenzothiazepine derivatives, -Jung teaches 2-(((3,3-dibutyl-7-methylthio-1,1-dioxido-5-phenyl-2,3,4,5- tetrahydrobenzo[b][1,4]thiazepine-8-yl)methyl)amino)acetic acid, which has structure: PNG media_image1.png 160 235 media_image1.png Greyscale , -Jung teaches R6 (R2 in the instant application) is C1-C6 alkyl, which significantly overlaps with the instant application (C1-C4 alkyl), -Surur teaches sulfides can take part in attractive non-bonding interactions, which maintain the active conformation of the molecule, due to the low-lying C-S σ* orbital on sulfur, -Surur teaches C-S σ* orbital allows for the phenomenon known as σ-holes, which possess a positive electrostatic potential and can interact with electron donating nitrogen or oxygen atoms, and sulfur can donate electrons into the σ-holes of various halogens, -Surur teaches sulfur-aromatic interactions are common in proteins and have significant impact on recognition and binding of pharmaceuticals, -Surur teaches sulfides feature longer bonds and narrow central bond angle, -Surur teaches sulfides undergo rapid oxidative metabolism, which can be of paramount importance if the aftermath of long-lasting activity outweighs the short-term benefits, and -Surur teaches that sulfides are prodrugs for sulfoxides and improve water solubility (page 6, column 1, paragraph 2). As such, an artisan having ordinary skill in the art would have been motivated to combine the selected teachings from Jung and Surur to arrive at a compound of Formula (I): PNG media_image2.png 142 181 media_image2.png Greyscale , specifically the compound: 2-(((3-butyl-3-ethyl-7-(methylthio)-1,1-dioxido-5-phenyl-2,3,4,5-tetrahydro-1,5-benzothiazepin-8- yl)methyl)thio)acetic acid, which has structure: PNG media_image3.png 141 257 media_image3.png Greyscale . Additionally, Applicant makes the assertion that the Examiner relied on the argument that nitrogen and sulfur are bioisostere equivalents. However, the Examiner notes that this is not one of the bases of the rejection and further does not dispute that nitrogen and sulfur are not bioisostere equivalents. Thus, the rejection of claims 1-2, 4-7, and 9-10 as being unpatentable over Jung in view of Surur is maintained. Claim Rejections – Nonstatutory Double Patenting 2. (Maintained) Claims 1-2, 4-7, and 9-10 were rejected on the ground of nonstatutory double patenting over claims 1-9 of U.S. Patent No. 10,975,045 in view of Jung (U.S. Patent No. 9,890,129, issued 13 Feb 2019; of record, see PTO-892 mailed 5 Feb 2026) and Surur (Arch. Pharm. Chem. Life Sci., 2019, 352(e1800248), 1-11; of record, see PTO-892 mailed 5 Feb 2026). Applicant's arguments filed 5 May 2026 have been fully considered but they are not persuasive. Applicant argues that there is no overlap of scope between the instant claims and the reference claims. Additionally, Applicant argues that the Office does not articulate motivation to modify or reasonable expectation of success. In response to Applicant's arguments against the references individually, one cannot show nonobviousness by attacking references individually where the rejections are based on combinations of references. See In re Keller, 642 F.2d 413, 208 USPQ 871 (CCPA 1981); In re Merck & Co., 800 F.2d 1091, 231 USPQ 375 (Fed. Cir. 1986).

Teleflex, Inc., 550 U.S. 398, 82 USPQ2d 1385 (2007). In this case, one of ordinary skill in the art would have been motivated to make such a selection, with a reasonable expectation of success, because: -‘045 teaches a compound of Formula (I): PNG media_image4.png 154 190 media_image4.png Greyscale , -Jung teaches compounds and compositions of aminoalkylbenzothiazepine derivatives, -Jung teaches 2-(((3,3-dibutyl-7-methylthio-1,1-dioxido-5-phenyl-2,3,4,5- tetrahydrobenzo[b][1,4]thiazepine-8-yl)methyl)amino)acetic acid, which has structure: PNG media_image1.png 160 235 media_image1.png Greyscale , -Jung teaches R6 (R2 in the instant application) is C1-C6 alkyl, which significantly overlaps with the instant application (C1-C4 alkyl), -Surur teaches sulfides can take part in attractive non-bonding interactions, which maintain the active conformation of the molecule, due to the low-lying C-S σ* orbital on sulfur, -Surur teaches C-S σ* orbital allows for the phenomenon known as σ-holes, which possess a positive electrostatic potential and can interact with electron donating nitrogen or oxygen atoms, and sulfur can donate electrons into the σ-holes of various halogens, -Surur teaches sulfur-aromatic interactions are common in proteins and have significant impact on recognition and binding of pharmaceuticals, -Surur teaches sulfides feature longer bonds and narrow central bond angle, -Surur teaches sulfides undergo rapid oxidative metabolism, which can be of paramount importance if the aftermath of long-lasting activity outweighs the short-term benefits, and -Surur teaches that sulfides are prodrugs for sulfoxides and improve water solubility (page 6, column 1, paragraph 2).

Thus, the rejection of claims 1-2, 4-7, and 9-10 on the ground of nonstatutory double patenting over claims 1-9 of U.S. Patent No. 10,975,045 in view of Jung and Surur is maintained. 3. (Maintained) Claims 1-2, 4-7, and 9-10 were rejected on the ground of nonstatutory double patenting over claims 1-2, 4-7, and 10 of U.S. Patent No. 10,941,127 in view of Jung (U.S. Patent No. 9,890,129, issued 13 Feb 2019; of record, see PTO-892 mailed 5 Feb 2026) and Surur (Arch. Pharm. Chem. Life Sci., 2019, 352(e1800248), 1-11; of record, see PTO-892 mailed 5 Feb 2026). Applicant's arguments filed 5 May 2026 have been fully considered but they are not persuasive.

Applicant argues that there is no overlap of scope between the instant claims and the reference claims. Additionally, Applicant argues that the Office does not articulate motivation to modify or reasonable expectation of success. In response to Applicant's arguments against the references individually, one cannot show nonobviousness by attacking references individually where the rejections are based on combinations of references. See In re Keller, 642 F.2d 413, 208 USPQ 871 (CCPA 1981); In re Merck & Co., 800 F.2d 1091, 231 USPQ 375 (Fed. Cir. 1986). In response to Applicant’s argument that there is no teaching, suggestion, or motivation to combine Jung and Surur, the Examiner recognizes that obviousness may be established by combining or modifying the teachings of the prior art to produce the claimed invention where there is some teaching, suggestion, or motivation to do so found either in the references themselves or in the knowledge generally available to one of ordinary skill in the art. See In re Fine, 837 F.2d 1071, 5 USPQ2d 1596 (Fed. Cir. 1988), In re Jones, 958 F.2d 347, 21 USPQ2d 1941 (Fed. Cir. 1992), and KSR International Co. v. Teleflex, Inc., 550 U.S. 398, 82 USPQ2d 1385 (2007). In this case, one of ordinary skill in the art would have been motivated to make such a selection, with a reasonable expectation of success, because: -‘185 teaches a compound of Formula (I): PNG media_image9.png 123 195 media_image9.png Greyscale , -Jung teaches compounds and compositions of aminoalkylbenzothiazepine derivatives, -Jung teaches 2-(((3,3-dibutyl-7-methylthio-1,1-dioxido-5-phenyl-2,3,4,5- tetrahydrobenzo[b][1,4]thiazepine-8-yl)methyl)amino)acetic acid, which has structure: PNG media_image1.png 160 235 media_image1.png Greyscale , -Jung teaches R6 (R2 in the instant application) is C1-C6 alkyl, which significantly overlaps with the instant application (C1-C4 alkyl), -Surur teaches sulfides can take part in attractive non-bonding interactions, which maintain the active conformation of the molecule, due to the low-lying C-S σ* orbital on sulfur, -Surur teaches C-S σ* orbital allows for the phenomenon known as σ-holes, which possess a positive electrostatic potential and can interact with electron donating nitrogen or oxygen atoms, and sulfur can donate electrons into the σ-holes of various halogens, -Surur teaches sulfur-aromatic interactions are common in proteins and have significant impact on recognition and binding of pharmaceuticals, -Surur teaches sulfides feature longer bonds and narrow central bond angle, -Surur teaches sulfides undergo rapid oxidative metabolism, which can be of paramount importance if the aftermath of long-lasting activity outweighs the short-term benefits, and -Surur teaches that sulfides are prodrugs for sulfoxides and improve water solubility (page 6, column 1, paragraph 2). As such, an artisan having ordinary skill in the art would have been motivated to combine the selected teachings from Jung and Surur to arrive at a compound of Formula (I): PNG media_image2.png 142 181 media_image2.png Greyscale , specifically the compound: 2-(((3-butyl-3-ethyl-7-(methylthio)-1,1-dioxido-5-phenyl-2,3,4,5-tetrahydro-1,5-benzothiazepin-8- yl)methyl)thio)acetic acid, which has structure: PNG media_image3.png 141 257 media_image3.png Greyscale . Thus, the rejection of claims 1-2, 4-7, and 9-10 on the ground of nonstatutory double patenting over claims 1-2, 4-7, and 10 of U.S. Application No. 18/164,185 (issued as U.S. Patent No. 12,187,690) in view of Jung and Surur is maintained. Conclusion No claim is allowed. THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
