Office Action

§112
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 . Status of Claims Claims 1-10 and 12-15 are currently pending as of the response and amendments filed on 3/6/26. Claim 11 was previously canceled. The amendments to the specification filed on 3/6/26 to correct typographical errors are acknowledged and accepted. The rejection of claims 1, 4, and 8 under 35 USC 112(b) is withdrawn in view of the amendments to claim 1. However, despite the amendments to claim 1, claim 6 remains rejected under 35 USC 112(b), as discussed below. Claims 1-10 and 12-15 were examined. Claims 1-5, 7-10, and 12-15 are allowed. Claim 6 is rejected. 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. Claim 6 is 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. Claim 6 depends indirectly from claim 1 and recites a number of compounds that lack antecedent basis from formula (I) in claim 1 (see below): 1-((1H-pyrazolo[3,4-b]pyridine-5-yl)methyl)-N-(3-fluoro-5-(trifluoromethyl)phenyl)indoline-6-carboxamide PNG media_image1.png 200 400 media_image1.png Greyscale . This compound lacks antecedent basis from amended claim 1, because while claim 1 allows R2 to include fluoro and CF3, only one group R2 is allowed. The other group attached to the phenyl ring, R3, doesn’t allow for fluoro or CF3. Claim 6 also recites N-(3-fluoro-5-(trifluoromethyl)phenyl)-1-(imidazo[1,2-a]pyrazin-3-ylmethyl)indoline-6-carboxamide: PNG media_image2.png 200 400 media_image2.png Greyscale . This compound lacks antecedent basis from amended claim 1, because while claim 1 allows R2 to include fluoro and CF3, only one group R2 is allowed. The other group attached to the phenyl ring, R3, doesn’t allow for fluoro or CF3. Claim 6 recites the compound N-(3-fluoro-5-(trifluoromethoxy)phenyl)-1-(imidazo[1,2-a]pyrazin-3-ylmethyl)indoline-6-carboxamide: PNG media_image3.png 200 400 media_image3.png Greyscale . This compound lacks antecedent basis from amended claim 1, because while claim 1 allows R2 to include fluoro and -OCF3, only one group R2 is allowed. The other group attached to the phenyl ring, R3, doesn’t allow for fluoro or -OCF3. Claim 6 also recites the compound N-(3-fluoro-5-(trifluoromethoxy)phenyl)-1-(imidazo[1,2-a]pyridine-3-ylmethyl)indoline-6-carboxamide: PNG media_image4.png 200 400 media_image4.png Greyscale . This compound lacks antecedent basis from amended claim 1, because while claim 1 allows R2 to include fluoro and -OCF3, only one group R2 is allowed. The other group attached to the phenyl ring, R3, doesn’t allow for fluoro or -OCF3. Claim 6 also recites the compound N-(3-fluoro-5-(trifluoromethyl)phenyl)-1-(imidazo[1,2-a]pyridine-3-ylmethyl)indoline-6-carboxamide: PNG media_image5.png 200 400 media_image5.png Greyscale . This compound lacks antecedent basis from amended claim 1, because while claim 1 allows R2 to include fluoro and CF3, only one group R2 is allowed. The other group attached to the phenyl ring, R3, doesn’t allow for fluoro or CF3. Claim 6 recites the compound 1-((1H-benzo[d]imidazole-5-yl)methyl)-N-(3-fluoro-5-(trifluoromethyl)phenyl)indoline-6-carboxamide: PNG media_image6.png 200 400 media_image6.png Greyscale . This compound lacks antecedent basis from amended claim 1, because while claim 1 allows R2 to include fluoro and CF3, only one group R2 is allowed. The other group attached to the phenyl ring, R3, doesn’t allow for fluoro or CF3. Information Disclosure Statement The IDS filed on 2/9/26 has been considered. 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).
