The pharmaceutical composition according to claim 40, wherein the pharmaceutically acceptable medium disperses the crystal form according to claim 1. Appropriate correction is required. See MPEP § 2173.02. Claim 11 is objected to because of the following informalities: for clarity, precision and to avoid issues under 35 U.S.C. § 112(b) and/or 35 U.S.C. § 112(d), the existing recitation should be replaced with the following recitation(s): 11. The pharmaceutical composition according to claim 9, wherein the pharmaceutical composition is formulated as a solution. 42. The pharmaceutical composition according to claim 11, wherein the solution comprises a pharmaceutically acceptable solvent. 43. The pharmaceutical composition according to claim 42, wherein the pharmaceutically acceptable solvent dissolves the crystal form according to claim 1. Appropriate correction is required. See MPEP § 2173.02. Claim Rejections - 35 U.S.C. § 112(b) The following is a quotation of the second paragraph of 35 U.S.C. § 112: (b) CONCLUSION. The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or joint inventor regards as the invention. Claims 1, 3, 5 and 9-11 are rejected under 35 U.S.C. § 112(b) as being indefinite for failing to set forth the subject matter which the inventor or joint inventor regards as the invention. The inventor or joint inventor should note that claim 1 recites the physicochemical property, A solid form of a pharmaceutically acceptable slat of a compound… of formula (I), in lines 1-6 of the claim. Similarly, the inventor or joint inventor should further note that the aforementioned physicochemical property renders the instant invention ambiguous, vague, incoherent, opaque and/or otherwise unclear to the examiner and fails to meet the statutory requirements of 35 U.S.C. § 112(b), since the limitation merely states a physicochemical property (i.e. solid form) without providing any clarity regarding how the physicochemical property is imparted. Likewise, the inventor or joint inventor should further note that the instantly recited solid form physicochemical property does not appear to emanate from and/or does not appear to be an inherent or salient property of the instantly recited pharmaceutically acceptable salts of (S)-(2-(6-(2-ethyl-5-fluoro-4-hydroxyphenyl)-1H-indazol-3-yl)-4,6-dihydropyrrolo[3,4-d]imidazol-5(1H)-yl)(3-hydroxypyrrolidin-1-yl)methanone of the formula (I). Next, the inventor or joint inventor should further note that the examiner is uncertain whether the instantly recited pharmaceutically acceptable salts of (S)-(2-(6-(2-ethyl-5-fluoro-4-hydroxyphenyl)-1H-indazol-3-yl)-4,6-dihydropyrrolo[3,4-d]imidazol-5(1H)-yl)(3-hydroxy-pyrrolidin-1-yl)methanone of the formula (I) require an additional unrecited component to be admixed therewith, such as a stabilizer, bulking agent, solvent, or buffer, to impart the solid form physicochemical property. Consequently, the inventor or joint inventor should further note that since the instantly recited pharmaceutically acceptable salts of (S)-(2-(6-(2-ethyl-5-fluoro-4-hydroxyphenyl)-1H-indazol-3-yl)-4,6-dihydropyrrolo[3,4-d]imidazol-5(1H)-yl)(3-hydroxypyrrolidin-1-yl)methanone of the formula (I) incorporate the aforementioned ambiguous, vague, incoherent, opaque and/or otherwise unclear solid form physicochemical property, the instantly recited pharmaceutically acceptable salts of (S)-(2-(6-(2-ethyl-5-fluoro-4-hydroxyphenyl)-1H-indazol-3-yl)-4,6-dihydro-pyrrolo[3,4-d]imidazol-5(1H)-yl)(3-hydroxypyrrolidin-1-yl)methanone of the formula (I) are rendered indefinite under 35 U.S.C. § 112(b), since one of ordinary skill in the art may not reasonably determine the metes and bounds of the instantly recited pharmaceutically acceptable salts of (S)-(2-(6-(2-ethyl-5-fluoro-4-hydroxyphenyl)-1H-indazol-3-yl)-4,6-dihydropyrrolo[3,4-d]imidazol-5(1H)-yl)(3-hydroxypyrrolidin-1-yl)methanone of the formula (I) due to an inability to establish the metes and bounds encompassed by the solid form physicochemical property. Then, the inventor or joint inventor should further note that [A] claim which omits matter disclosed to be essential to the invention, as described in the specification or in other statements of record, may also be rejected under 35 U.S.C. § 112(a), as not enabling. {See In re Mayhew, 527 F.2d 1229, 188 USPQ 356 (CCPA 1976); and MPEP § 2164.08(c)}. Moreover, the inventor or joint inventor should further note that [C]laims which depend from indefinite claims are also indefinite. {See Ex parte Cordova, 10 USPQ 2d 1949, 1952 (PTO Bd. App. 1989)}. The examiner suggests amending the claims, particularly as stated in the section above entitled Claim Objections, to overcome this rejection. Claim 5 is further rejected under 35 U.S.C. § 112(b) as being indefinite for failing to set forth the subject matter which the inventor or joint inventor regards as the invention. The inventor or joint inventor should note that a broad limitation together with a narrow limitation that falls within the broad limitation (in the same claim) is considered indefinite, since the resulting claim does not clearly set forth the metes and bounds of the patent protection desired. See MPEP § 2173.05(c), MPEP § 2173.05(h), and/or Eli Lilly & Co. v. Teva Parenteral Meds., 845 F.3d 1357, 1371, 121 USPQ2d 1277, 1287 (Fed. Cir. 2017). Similarly, the inventor or joint inventor should further note that claim 5 recites the broad limitation, benzenesulfonate, citrate, fumarate, hydrochloride, maleate, methanesulfonate, mucinate, phosphate, L-tartrate, and p-tolunesulfonate, respectively, and the claim also recites maleate, methanesulfonate, and phosphate, respectively, which is the narrower statement of the limitation. Likewise, the inventor or joint inventor should further note the explanation given by the Board of Patent Appeals and Interferences in Ex parte Wu, 10 USPQ2d 2031, 2033 (Bd. Pat. App. & Inter. 1989), pertaining to where broad language is followed by such as and then narrow language. The Board stated that this can render a claim indefinite by raising a question or doubt as to whether the feature introduced by such language is (a) merely exemplary of the remainder of the claim, and consequently, not required, or (b) a required feature of the claim. Moreover, the inventor or joint inventor should further note the explanation given by the Board of Patent Appeals and Interferences in the decisions of Ex parte Steigewald, 131 USPQ 74 (Bd. App. 1961); Ex parte Hall, 83 USPQ 38 (Bd. App. 1948); and Ex parte Hasche, 86 USPQ 481 (Bd. App. 1949). The examiner suggests amending the claim, particularly as stated in the section above entitled Claim Objections, to overcome this rejection. Claim 6 is rejected under 35 U.S.C. § 112(b) as being indefinite for failing to set forth the subject matter which the inventor or joint inventor regards as the invention. The inventor or joint inventor should note that a broad limitation together with a narrow limitation that falls within the broad limitation (in the same claim) is considered indefinite, since the resulting claim does not clearly set forth the metes and bounds of the patent protection desired. See MPEP § 2173.05(c), MPEP § 2173.05(h), and/or Eli Lilly & Co. v. Teva Parenteral Meds., 845 F.3d 1357, 1371, 121 USPQ2d 1277, 1287 (Fed. Cir. 2017). Similarly, the inventor or joint inventor should further note that claim 6 recites the broad limitation, benzenesulfonate, citrate, fumarate, hydrochloride, maleate, methanesulfonate, mucinate, phosphate, L-tartrate, and p-tolunesulfonate, respectively, and the claim also recites maleate, methanesulfonate, and phosphate, respectively, which is the narrower statement of the limitation. Likewise, the inventor or joint inventor should further note the explanation given by the Board of Patent Appeals and Interferences in Ex parte Wu, 10 USPQ2d 2031, 2033 (Bd. Pat. App. & Inter. 1989), pertaining to where broad language is followed by such as and then narrow language. The Board stated that this can render a claim indefinite by raising a question or doubt as to whether the feature introduced by such language is (a) merely exemplary of the remainder of the claim, and consequently, not required, or (b) a required feature of the claim. Moreover, the inventor or joint inventor should further note the explanation given by the Board of Patent Appeals and Interferences in the decisions of Ex parte Steigewald, 131 USPQ 74 (Bd. App. 1961); Ex parte Hall, 83 USPQ 38 (Bd. App. 1948); and Ex parte Hasche, 86 USPQ 481 (Bd. App. 1949). The examiner suggests amending the claim, particularly as stated in the section above entitled Claim Objections, to overcome this rejection. Claim 7 is rejected under 35 U.S.C. § 112(b) as being indefinite for failing to set forth the subject matter which the inventor or joint inventor regards as the invention. The inventor or joint inventor should note that a broad limitation together with a narrow limitation that falls within the broad limitation (in the same claim) is considered indefinite, since the resulting claim does not clearly set forth the metes and bounds of the patent protection desired. See MPEP § 2173.05(c), MPEP § 2173.05(h), and/or Eli Lilly & Co. v. Teva Parenteral Meds., 845 F.3d 1357, 1371, 121 USPQ2d 1277, 1287 (Fed. Cir. 2017). Similarly, the inventor or joint inventor should further note that claim 7 recites the broad limitation, …having a powder X-ray diffraction pattern (XRPD) having one or more characteristic peaks at a diffraction angle (2q) selected from…, and the claim also recites …preferably having a powder X-ray diffraction pattern (XRPD) having one or more characteristic peaks at a diffraction angle (2q) selected from…, which is the narrower statement of the limitation. Likewise, the inventor or joint inventor should further note the explanation given by the Board of Patent Appeals and Interferences in Ex parte Wu, 10 USPQ2d 2031, 2033 (Bd. Pat. App. & Inter. 1989), pertaining to where broad language is followed by such as and then narrow language. The Board stated that this can render a claim indefinite by raising a question or doubt as to whether the feature introduced by such language is (a) merely exemplary of the remainder of the claim, and consequently, not required, or (b) a required feature of the claim. Moreover, the inventor or joint inventor should further note the explanation given by the Board of Patent Appeals and Interferences in the decisions of Ex parte Steigewald, 131 USPQ 74 (Bd. App. 1961); Ex parte Hall, 83 USPQ 38 (Bd. App. 1948); and Ex parte Hasche, 86 USPQ 481 (Bd. App. 1949). The examiner suggests amending the claims, particularly as stated in the section above entitled Claim Objections, to overcome this rejection. Claims 10 and 11 are further rejected under 35 U.S.C. § 112(b) as being indefinite for failing to set forth the subject matter which the inventor or joint inventor regards as the invention. The inventor or joint inventor should note that claim 10 recites the limitation, The pharmaceutical composition according to claim 9, which is in the form of a dispersion comprising a pharmaceutically acceptable dispersing medium and the solid form of the compound according to claim 1 dispersed in the dispersing medium, in lines 1-3 of the claim. There is insufficient antecedent basis, in claim 9, for this limitation, with respect to the pharmaceutical composition comprising a solid form of a pharmaceutically acceptable salt of (S)-(2-(6-(2-ethyl-5-fluoro-4-hydroxyphenyl)-1H-indazol-3-yl)-4,6-dihydropyrrolo[3,4-d]imidazol-5(1H)-yl)(3-hydroxy-pyrrolidin-1-yl)methanone of the formula (I). According to claim 1, a solid form is recited instead of a compound, with respect to the solid form of a pharmaceutically acceptable salt of (S)-(2-(6-(2-ethyl-5-fluoro-4-hydroxyphenyl)-1H-indazol-3-yl)-4,6-dihydropyrrolo[3,4-d]imidazol-5(1H)-yl)(3-hydroxypyrrolidin-1-yl)methanone of the formula (I). Moreover, the inventor or joint inventor should further note that [C]laims which depend from indefinite claims are also indefinite. {See Ex parte Cordova, 10 USPQ 2d 1949, 1952 (PTO Bd. App. 1989)}. The examiner suggests amending the claims, particularly as stated in the section above entitled Claim Objections, to overcome this rejection. Claim Rejections - Obviousness-type Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute), so as to prevent the unjustified or improper timewise extension of the right to exclude granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory obviousness-type double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined invention claim is not patentably distinct from the reference claims because the examined invention claim is either anticipated by, or would have been obvious over, the reference claims. {See In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); and In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969)}. US Patent No. 11,629,148 PNG media_image1.png 200 400 media_image1.png Greyscale PNG media_image4.png 200 400 media_image4.png Greyscale Consequently, at least claims 1, 3, 5 and 9-11 are rejected on the ground of nonstatutory obviousness-type double patenting as being unpatentable over at least claim 11 of US Patent No. 11,629,148. Although the conflicting claims are not identical, they are not patentably distinct from each other because claim 11 in US 11,629,148 recites (S)-(2-(6-(2-ethyl-5-fluoro-4-hydroxyphenyl)-1H-indazol-3-yl)-4,6-dihydro-pyrrolo[3,4-d]imidazol-5(1H)-yl)(3-hydroxypyrrolidin-1-yl)-methanone, shown to the left, or a pharmaceutically acceptable salt thereof, which provides overlapping subject matter with respect to the instantly recited solid form of a pharmaceutically acceptable salt of (S)-(2-(6-(2-ethyl-5-fluoro-4-hydroxyphenyl)-1H-indazol-3-yl)-4,6-dihydropyrrolo[3,4-d]-imidazol-5(1H)-yl)(3-hydroxypyrrolidin-1-yl)methanone of the formula (I), shown to the right. The inventor or joint inventor should note that [T]he discovery of a previously unappreciated property of a prior art compound, or of a scientific explanation for the prior art’s functioning, does not render the old compound patentably new to the discoverer. {See Atlas Powder Co. v. Ireco Inc., 190 F.3d 1342, 1347, 51 USPQ2d 1943, 1947 (Fed. Cir. 1999)}. Similarly, the inventor or joint inventor should further note that [T]he claiming of a new use, new function or unknown property which is inherently present in the prior art does not necessarily make the claim patentable. {See In re Best, 562 F.2d 1252, 1254, 195 USPQ 430, 433 (CCPA 1977); and In re Crish, 393 F.3d 1253, 1258, 73 USPQ2d 1364, 1368 (Fed. Cir. 2004)}. Likewise, the inventor or joint inventor should note that [W]hen the claim recites using an old compound and the use is directed to a result or property of that compound, then the claim is anticipated. {See In re May, 574 F.2d 1082, 1090, 197 USPQ 601, 607 (CCPA 1978); and In re Tomlinson, 363 F.2d 928, 150 USPQ 623 (CCPA 1966)}. Next, the inventor or joint inventor should further note that [P]roducts of identical chemical composition may not have mutually exclusive properties. A chemical composition and its properties are inseparable. Therefore, if the prior art teaches the identical chemical structure, the properties the inventor or joint inventor discloses and/or claims are necessarily present. {See In re Spada, 911 F.2d 705, 709, 15 USPQ2d 1655, 1658 (Fed. Cir. 1990)}. Moreover, the inventor or joint inventor should further note that [I]t is obvious to add a carrier or solvent to an unpatentable compound. {See Ex parte Douros and Vanderweff, 163 USPQ 667, (BPAI 1968)}. US Patent No. 12,180,215 PNG media_image4.png 200 400 media_image4.png Greyscale At least claims 1, 3, 5 and 9-11 are further rejected on the ground of nonstatutory obviousness-type double patenting as being unpatentable over at least claim 18 of US Patent No. 12,180,215. Although the conflicting claims are not identical, they are not patentably distinct from each other because claim 18 in US 12,180,215 recites (S)-(2-(6-(2-ethyl-5-fluoro-4-hydroxyphenyl)-1H-indazol-3-yl)-4,6-dihydro-pyrrolo[3,4-d]imidazol-5(1H)-yl)(3-hydroxypyrrolidin-1-yl)-methanone, shown to the left, or a pharmaceutically acceptable salt thereof, which provides overlapping subject matter with respect to the instantly recited solid form of a pharmaceutically acceptable salt of (S)-(2-(6-(2-ethyl-5-fluoro-4-hydroxyphenyl)-1H-indazol-3-yl)-4,6-dihydropyrrolo[3,4-d]imidazol-5(1H)-yl)(3-hydroxypyrrolidin-1-yl)methanone of the formula (I), shown to the right below. PNG media_image1.png 200 400 media_image1.png Greyscale The inventor or joint inventor should note that [T]he discovery of a previously unappreciated property of a prior art compound, or of a scientific explanation for the prior art’s functioning, does not render the old compound patentably new to the discoverer. {See Atlas Powder Co. v. Ireco Inc., 190 F.3d 1342, 1347, 51 USPQ2d 1943, 1947 (Fed. Cir. 1999)}. Similarly, the inventor or joint inventor should further note that [T]he claiming of a new use, new function or unknown property which is inherently present in the prior art does not necessarily make the claim patentable. {See In re Best, 562 F.2d 1252, 1254, 195 USPQ 430, 433 (CCPA 1977); and In re Crish, 393 F.3d 1253, 1258, 73 USPQ2d 1364, 1368 (Fed. Cir. 2004)}. Likewise, the inventor or joint inventor should note that [W]hen the claim recites using an old compound and the use is directed to a result or property of that compound, then the claim is anticipated. {See In re May, 574 F.2d 1082, 1090, 197 USPQ 601, 607 (CCPA 1978); and In re Tomlinson, 363 F.2d 928, 150 USPQ 623 (CCPA 1966)}.

A chemical composition and its properties are inseparable. Therefore, if the prior art teaches the identical chemical structure, the properties the inventor or joint inventor discloses and/or claims are necessarily present. {See In re Spada, 911 F.2d 705, 709, 15 USPQ2d 1655, 1658 (Fed.

Then, the inventor or joint inventor should further note that [I]t is obvious to add a carrier or solvent to an unpatentable compound. {See Ex parte Douros and Vanderweff, 163 USPQ 667, (BPAI 1968)}. Moreover, the inventor or joint inventor should further note that a timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 37 CFR 1.321(d) may be used to overcome an actual or provisional rejection based on a nonstatutory double patenting ground, provided the conflicting invention or patent either is shown to be commonly owned with this invention, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. Furthermore, the inventor or joint inventor should also note that the USPTO internet Web site contains terminal disclaimer forms which may be used, and the inventor or joint inventor is encouraged to visit http://www.uspto.gov/forms/, where (i) the filing date of the invention will determine what form should be used, and (ii) a web-based eTerminal Disclaimer may be filled out completely online using web-screens, respectively. Also, the inventor or joint inventor should further note that an eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. Finally, for more information about eTerminal Disclaimers, the inventor or joint inventor should refer to http://www.uspto.gov/patents/process/file/efs/guidance/eTD-info-I.jsp. The examiner suggests amending the claims, particularly as stated in the section above entitled Claim Objections, to overcome this rejection. Allowable Subject Matter No claims are allowed.
