There are many factors to be considered when determining whether there is sufficient evidence to support a determination that a disclosure does not satisfy the enablement requirement and whether any necessary experimentation is undue. These factors include, but are not limited to: (a) breadth of the claims; (b) nature of the invention; (c) state of the prior art; (d) level of one of ordinary skill in the art; (e) level of predictability in the art; (f) amount of direction provided by the inventor or joint inventor; (g) existence of working examples; and (h) quantity of experimentation needed to make or use the invention based on the content of the disclosure. {See Ex parte Forman 230 USPQ 546 (Bd. Pat. App. & Inter. 1986); and In re Wands, 8 USPQ2d 1400 (Fed. Cir. 1988)}.
The above factors, regarding the instant invention, are summarized as follows:

(a) Breadth of the claims - the breadth of the claims includes a method for selectively inhibiting ROS1 over TRK… said method comprising administering… a substituted macrocycle of the Formula (I), shown to the right, or a pharma-ceutical composition thereof;
(b) Nature of the invention - the nature of the invention is performance of a method for selectively inhibiting ROS1 over TRK… said method comprising administering… a substituted macrocycle of the Formula (I), shown to the right above, or a pharmaceutical composition thereof;
(c) State of the prior art - Nature Reviews: Drug Discovery offers a snapshot of the state of the drug development art. Herein, drug development is stated to follow the widely accepted Ehrlich model which includes: (1) development of a broad synthetic organic chemistry program; (2) subsequent testing of compounds in an appropriate laboratory model for the disease to be treated; and (3) screening of compounds with low toxicity in prospective clinical trials (Jordan, V. C. Nature Reviews: Drug Discovery, 2, 2003, 205). Moreover, WO 21/226208, as provided in the file and cited on the IDS, provides a synthesis of the substituted macrocycles of the Formula (I) administered within the instantly recited method for selectively inhibiting ROS1 over TRK {Tang, et al. WO 21/226208, 2021};
(d) Level of one of ordinary skill in the art - the artisans performing the inventor’s or joint inventor’s method for selectively inhibiting ROS1 over TRK… said method comprising administering… a substituted macrocycle of the Formula (I), wherein the 5-membered heteroarylene of X is not attached to the aromatic ring comprising Q and -CH2- on adjacent atoms, or a pharmaceutical composition thereof, would be a collaborative team of synthetic chemists and/or health practitioners, possessing commensurate degree level and/or skill in the art, as well as several years of professional experience;
(e) Level of predictability in the art - Synthetic organic chemistry is quite unpredictable (See In re Marzocchi and Horton 169 USPQ at 367 ¶3). Similarly, it is unclear based on the combination of the instant specification, and Tang, et al. in WO 21/226208, as provided in the file and cited on the IDS, whether the substituted macrocycles of the Formula (I) administered within the instantly recited method for selectively inhibiting ROS1 over TRK, wherein the 5-membered heteroarylene of X is not attached to the aromatic ring comprising Q and -CH2- on adjacent atoms, or a pharmaceutical composition thereof, are enabled. Moreover, the following excerpt is taken from Dörwald, which has relevance to the synthesis of substituted macrocycles of the Formula (I) administered within the instantly recited method for selectively inhibiting ROS1 over TRK, wherein the 5-membered heteroarylene of X is not attached to the aromatic ring comprising Q and -CH2- on adjacent atoms, or a pharmaceutical composition thereof (Dörwald, F. Zaragoza. Side Reactions in Organic Synthesis: A Guide to Successful Synthesis Design, Weinheim: WILEY-VCH Verlag GmbH & Co. KGaA, 2005, Preface):
Most non-chemists would probably be horrified if they were to learn how many attempted syntheses fail, and how inefficient research chemists are. The ratio of successful to unsuccessful chemical experiments in a normal research laboratory is far below unity, and synthetic research chemists, in the same way as most scientists, spend most of their time working out what went wrong, and why.
Despite the many pitfalls lurking in organic synthesis, most organic chemistry textbooks and research articles do give the impression that organic reactions just proceed smoothly and that the total synthesis of complex natural products, for instance, is maybe a labor-intensive but otherwise undemanding task. In fact, most syntheses of structurally complex natural products are the result of several years of hard work by a team of chemists, with almost every step requiring careful optimization. The final synthesis usually looks quite different from that originally planned, because of unexpected difficulties encountered in the initially chosen synthetic sequence. Only the seasoned practitioner who has experienced for himself the many failures and frustrations which the development (sometimes even the repetition) of a synthesis usually implies will be able to appraise such work.
Chemists tend not to publish negative results, because these are, as opposed to positive results, never definite (and far too copious).
(f) Amount of direction provided by the inventor - the invention lacks direction with respect to making and/or using (performing) a method for selectively inhibiting ROS1 over TRK… said method comprising administering… a substituted macrocycle of the Formula (I), wherein the 5-membered heteroarylene of X is not attached to the aromatic ring comprising Q and -CH2- on adjacent atoms, or a pharmaceutical composition thereof;
(g) Existence of working examples - the inventor or joint inventor has provided sufficient guidance to make and/or use (perform) a method for selectively inhibiting ROS1 over TRK… said method comprising administering… a substituted macrocycle of the Formula (I), wherein the 5-membered heteroarylene of X is attached to the aromatic ring comprising Q and -CH2- on adjacent atoms, or a pharmaceutical composition thereof; however, the disclosure is insufficient to allow extrapolation of the limited examples to enable performing the instantly recited method for selectively inhibiting ROS1 over TRK… said method comprising administering… a substituted macrocycle of the Formula (I), wherein the 5-membered heteroarylene of X is not attached to the aromatic ring comprising Q and -CH2- on adjacent atoms, or a pharmaceutical composition thereof. The specification lacks working examples of performing a method for selectively inhibiting ROS1 over TRK… said method comprising administering… a substituted macrocycle of the Formula (I), wherein the 5-membered heteroarylene of X is not attached to the aromatic ring comprising Q and -CH2- on adjacent atoms, or a pharmaceutical composition thereof.
Within the specification, [A]t least one specific operative embodiment or example of the invention must be set forth. The example(s) and description should be of sufficient scope as to justify the scope of the claims. Markush claims must be provided with support in the disclosure for each member of the Markush group. Where the constitution and formula of a chemical compound is stated only as a probability or speculation, the disclosure is not sufficient to support claims identifying the compound by such composition or formula. See MPEP § 608.01(p) and MPEP § 2173.05.
(h) Quantity of experimentation needed to make or use the invention based on the content of the disclosure - predicting whether a recited compound, and/or a pharmaceutical composition thereof, is in fact one that produces a desired physiological effect at a therapeutic concentration and with useful kinetics, is filled with experimental uncertainty, and without proper guidance, would involve a substantial amount of experimentation (Jordan, V. C. Nature Reviews: Drug Discovery, 2, 2003, 205-213). Similarly, the specification, as originally filed, including any references incorporated therein, fails to provide the necessary support required by 35 U.S.C. § 112(a) to enable performing the instantly recited method for selectively inhibiting ROS1 over TRK… said method comprising administering… a substituted macrocycle of the Formula (I), wherein the 5-membered heteroarylene of X is not attached to the aromatic ring comprising Q and -CH2- on adjacent atoms, or a pharmaceutical composition thereof. Thus, it is unclear, based on the guidance provided by the specification, whether a substituted macrocycle of the Formula (I) administered within the instantly recited method for selectively inhibiting ROS1 over TRK, wherein the 5-membered heteroarylene of X is not attached to the aromatic ring comprising Q and -CH2- on adjacent atoms, or a pharmaceutical composition thereof, is either synthetically feasible or possesses utility as a therapeutic agent, useful in a method for selectively inhibiting ROS1 over TRK… said method comprising administering… a substituted macrocycle of the Formula (I), or a pharmaceutical composition thereof.
A conclusion of lack of enablement means that, based on the evidence regarding each of the above factors, the specification, at the time the invention was filed, would not have taught one skilled in the art how to make and/or use the full scope of the claimed invention without undue experimentation. {See In re Wright, 999 F.2d 1557, 1562, 27 USPQ2d 1510, 1513 (Fed. Cir. 1993)}.
The determination that undue experimentation would have been needed to make and use the claimed invention is not a single, simple factual determination. Rather, it is a conclusion reached by weighing all the above noted factual considerations. (See In re Wands, 858 F.2d at 737, 8 USPQ2d at 1404). These factual considerations are discussed comprehensively in MPEP § 2164.08 (scope or breadth of the claims), § 2164.05(a) (nature of the invention and state of the prior art), § 2164.05(b) (level of one of ordinary skill), § 2164.03 (level of predictability in the art and amount of direction provided by the inventor or joint inventor), § 2164.02 (the existence of working examples) and § 2164.06 (quantity of experimentation needed to make or use the invention based on the content of the disclosure).
Based on a preponderance of the evidence presented herein, the conclusion that the inventor or joint inventor is insufficiently enabled for making and/or using (performing) a method for selectively inhibiting ROS1 over TRK… said method comprising administering… a substituted macrocycle of the Formula (I), wherein the 5-membered heteroarylene of X is not attached to the aromatic ring comprising Q and -CH2- on adjacent atoms, or a pharmaceutical composition thereof, is clearly justified.
The examiner suggests amending the claims, particularly as stated in the section above entitled Claim Objections, to overcome this rejection.
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 43-45, 51 and 52 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 43 recites the limitation, The method of claim 42, wherein the cancer is…, in line 1 of the claim. There is insufficient antecedent basis, in claim 42, for this limitation, with respect to the method for selectively inhibiting ROS1 over TRK. According to claim 42, the cancer is recited as a solid tumor, with respect to the method for selectively inhibiting ROS1 over TRK.
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 49 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 claim 49 recites the limitation, The method of claim 46, wherein the ROS1 positive cancer has a G2032R mutation, in lines 1-2 of the claim. There is insufficient antecedent basis, in claim 46, for this limitation, with respect to the method for selectively inhibiting ROS1 over TRK. According to claim 46, a ROS1 positive cancer is not recited, with respect to the method for selectively inhibiting ROS1 over TRK.
The examiner suggests amending the claim, 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)}.

Consequently, claims 26, 29 and 31-57 are rejected on the ground of nonstatutory obviousness-type double patenting as being unpatentable over at least claims 1-6, 9 and 21 of US Patent No. 11,542,278. Although the conflicting claims are not identical, they are not patentably distinct from each other because claim 1 in US 11,542,278 recites substituted macrocycles of the Formula (I), shown to the left above, where Q = CH; R1 = -CH3; X is shown to the right above, wherein, at C-3, R2 = -halo and at N3, R2 = -CH2-C3-4 cycloalkyl; Y is shown to the left, wherein R3 = -C1-4 alkyl; R4 = -F; and Z = -CR5, wherein R5 = -H, respectively, which are administered within the instantly recited method for selectively inhibiting ROS1 over TRK… comprising administering… a substituted macrocycle of the Formula (I), shown to the right above, where Q = CH; R1 = -CH3; X = -5-membered heteroarylene, substituted with 0, 1, or 2 R2 substituents; R2 = -halo and R2 = -CH2-C3-4 cycloalkyl; Y = -5- or 6-membered heteroarylene, substituted with 0, 1, or 2 R3 substituents; R3 = -C1-4 alkyl; R4 = -F; and Z = -CR5, wherein R5 = -H, respectively.
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 [A] claim to a method of using a composition is not patentably distinct from an earlier claim to the identical composition in a patent disclosing the identical use. {See Sun Pharmaceuticals Industries Ltd. v. Eli Lilly and Co., 611 F.3d 1381, 95 USPQ2d 1797 (Fed. Cir. 2010); Pfizer, Inc. v. Teva Pharmaceuticals USA, Inc., 518 F.3d 1353, 1363, 86 USPQ2d 1001 (Fed. Cir. 2008); and Geneva

At least claims 26, 29, 31-49 and 53 are further rejected on the ground of nonstatutory obviousness-type double patenting as being unpatentable over at least claims 1-5, 18 and 31 of US Patent No. 11,667,649. Although the conflicting claims are not identical, they are not patentably distinct from each other because claim 1 in US 11,667,649 recites substituted macrocycles of the Formula (I), shown to the left above, where Q = CH; R1 = -CH3; X = -pyrazolylene, substituted with 0, 1, or 2 R2 substituents; R2 = -halo and R2 = -C3-4 cycloalkylmethyl; Y = -pyrazolylene, substituted with 0, 1, or 2 R3 substituents; R3 = -C1-4 alkyl; R4 = -F; and Z = -CR5, wherein R5 = -H, respectively, which are administered within the instantly recited method for selectively inhibiting ROS1 over TRK… comprising administering… a substituted macrocycle of the Formula (I), shown to the right below, where Q = CH; R1 = -CH3; X = -5-membered heteroarylene, substituted with 0, 1, or 2 R2 substituents; R2 = -halo and R2 = -CH2-C3-4 cycloalkyl; Y = -5- or 6-membered heteroarylene, substituted with 0, 1, or 2 R3 substituents; R3 = -C1-4 alkyl; R4 = -F; and Z = -CR5, wherein R5 = -H, respectively.
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.
