The following rejections are necessitated by amendment: Claim Rejections - 35 USC § 102 The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. Claims 1-2, 49, 51, 70, 78, 137-138, 141, and 144 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by CAS Registry File 76167-43-6 (entered into STN November 16th, 1984; hereinafter referred to as CAS Registry File 1). CAS Registry File 1 teaches a compound having the following structure: PNG media_image1.png 138 390 media_image1.png Greyscale This compound reads on a compound of Formula (I) as recited at instant Claim 1 when the variables are defined as follows: X is CR3, wherein R3 is hydrogen. Y and Z are each N. T is PNG media_image2.png 72 83 media_image2.png Greyscale , wherein m is 0. R1 and R2 are each hydrogen. R4 is unsubstituted alkyl, wherein alkyl is methyl. R6 and R7 are each hydrogen. s is 0. Regarding Claim 2, this compound reads on a compound of formula (I-gg). Claims 1, 51, 55, 70, 137-138, 141, and 144 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by WO2003/082855 (Machine translation provided; hereinafter referred to as WO ‘855). At Page 57, WO ‘855 teaches compounds of the formula: PNG media_image3.png 110 175 media_image3.png Greyscale At Page 57, entry 107, WO’855 defines R1 as PNG media_image4.png 52 153 media_image4.png Greyscale and R7a as PNG media_image5.png 50 99 media_image5.png Greyscale . For clarity, the full structure of this compound is: PNG media_image6.png 326 469 media_image6.png Greyscale This structure reads on a compound of formula (I) as recited at instant Claim 1 when the variables are defined as follows: X is CR3, wherein R3 is cyano. Y and Z are each N. T is PNG media_image2.png 72 83 media_image2.png Greyscale , wherein m is 0. R1 is N(RA)2, wherein one RA is hydrogen, and the other is unsubstituted alkyl, wherein alkyl is pentyl. R2 is hydrogen. R4 is unsubstituted alkyl, wherein alkyl is methyl. R6 and R7 are each hydrogen. s is 0. Claims 1-2, 45, 51, 78, 137-138, 141, and 144 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by CAS Registry File 1309115-40-9 (entered into STN June 13th, 2011; hereinafter referred to as CAS Registry File 2). CAS Registry File 2 teaches the following compound: PNG media_image7.png 221 478 media_image7.png Greyscale This compound reads on a compound of formula (I) as recited at instant Claim 1 when the variables are defined as follows: X and Y are each N. T is PNG media_image2.png 72 83 media_image2.png Greyscale , wherein m is 0. Z is CR3, wherein R3 is hydrogen. R1 is hydrogen. R2 is substituted alkyl, wherein alkyl is ethyl, substituted with N(Rbb)2, as specified at Page 27, Paragraph 0048 of the instant specification, wherein each Rbb is hydrogen, as specified at Page 28, Paragraph 0048 of the instant specification. R4 is unsubstituted alkyl, wherein alkyl is methyl. R6 and R7 are each hydrogen. s is 0. Regarding Claim 2, this compound reads on a compound of formula (I-a). Claims 1-2, 51, 78, 137-138, 141, and 144 are rejected under 35 U.S.C. 102(a)(1) as being anticipated CAS Registry File 2286943-74-4 (entered into STN March 15th, 2019; cited on Applicant’s Information Disclosure Statement filed January 14th, 2026; hereinafter referred to as CAS Registry File 3). CAS Registry File 3 teaches the following compound: PNG media_image8.png 241 446 media_image8.png Greyscale This compound reads on a compound of formula (I) as recited at Claim 1 when the variables are defined as follows: X and Z are each N. Y is CR3, wherein R3 is hydrogen. T is PNG media_image2.png 72 83 media_image2.png Greyscale , wherein m is 0. R1 is hydrogen. R2 is -N(RA)2, wherein each RA is hydrogen. R4 is unsubstituted alkyl, wherein alkyl is methyl. R6 and R7 are each hydrogen. s is 0. Regarding Claim 2, this compound reads on a compound of formula (I-f). Allowable Subject Matter Claims 80, 102, 105, 152, and 160 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Conclusion Claims 1-2, 45, 49, 51, 55, 70, 78, 137-138, 141, and 144 are rejected. Claims 80, 102, 105, 152, and 160 are objected to. No claim is 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).
