Office Action

§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 . FINAL ACTION Priority Instant application 17/923,875 filed on 11/07/22 claims benefit as follow: CONTINUING DATA: PNG media_image1.png 30 331 media_image1.png Greyscale Status of the Application The amendment filled on 03/11/2026 have been entered. Claims 4, 6, 7-11, 13-17 and 21-23 are pending. Information Disclosure Statement The information disclosure statements (IDS) submitted on 05/19/2026, 10/15/2025, 10/07/2025, 09/04/2025, 01/17/2025, 11/13/2024, 11/12/2024, 11/06/2023, 05/26/2023 were in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statements are being considered by the examiner. Response to Arguments/Amendments The amendment filled on 03/11/2026 have been entered. Applicant’s amendment overcome all rejections of record; therefore, all rejections of record are withdrawn. However, Applicant’s amendment necessitated new grounds of rejection presented in this office action. Election/Restrictions Claims 11, 13-17 and 21-23 are withdrawn from further consideration pursuant to 37 CFR 1.142(b), as being drawn to a nonelected invention, there being no allowable generic or linking claim.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 10/13/2025. Regarding species election, Applicant elected without traverse Example 25 in the reply filed on 10/13/2025. PNG media_image2.png 175 696 media_image2.png Greyscale Species Election A careful review of the prior art has indicated that elected species is free of the prior art. A claim directed to the elected species in independent form would be free of the prior art. The examiner has moved onto alternative species recited in the instant claim 4, and subsequent examination is based on this species expansion. The expended species is instant example 3, recited in instant claim 4: PNG media_image3.png 106 614 media_image3.png Greyscale It should be noted that the above compound has been entered to STN on 24 Aug 1990: PNG media_image4.png 585 848 media_image4.png Greyscale Further, it should be noted that the above compound is also known as N-[3-( 4-Fluorophenyl)-propyl]-1-deoxynojirimycin (see EP-0350012-A2, Table 5). Claim Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claims 4, 6, 7, 8, 9 and 10 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by EP-0350012-A2, evidenced by STN (RN 128985-12-6, entered to STN 24 Aug 1990). EP-0350012-A2 discloses antiviral compositions comprising N-[3-( 4-Fluorophenyl)-propyl]-1-deoxynojirimycin (see Table 5 on page 8): As evidenced by STN, N-[3-( 4-Fluorophenyl)-propyl]-1-deoxynojirimycin has the following structure: PNG media_image5.png 826 786 media_image5.png Greyscale Regarding instant claims 6-9, it should be noted that the instant claims are directed to GBA2 inhibitors. However, chemical compound inherently possesses its properties. Since EP-0350012-A2 teaches the same structure as recited by the instant claims the properties recited in instant claims 6-9 are necessarily present (see also MPEP § 2112). Regarding instant claim 10, EP-0350012-A2 teaches pharmaceutical composition comprising the compound in a combination with a pharmaceutically acceptable carrier (see page 4, lines 15-18): PNG media_image6.png 73 669 media_image6.png Greyscale Since the teachings of EP-0350012-A2 meet all the limitations of instant claims, the instant claims are anticipated. Conclusion No claims are allowed. Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). 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.
