Office Action

§112
DETAILED ACTION Claims 1, 4-10, 12, 22-26, 31-33 are pending in the instant application. Applicant's election with traverse of group (III) in the reply filed on 05/22/2026 is acknowledged. The applicant’s traverse is on two grounds as followed: Applicant respectfully submits that unity is present between the compounds of general formula (I) of claim 1 (groups I-IV), because those compounds (1) have a common property or activity, and (2) a common structure is present, and/or all alternatives belong to a recognized class of chemical compounds in the art to which the invention pertains. Applicant’s argument is not persuasive for the following reasons: The common core is PNG media_image1.png 68 124 media_image1.png Greyscale , which X is C in class 546 and X is N in class 544. Therefore, has different class and different search. The search is extremely burden because groups I-VIII are in different classes and subclasses. Different searches need for different classes (546, 544, 514). Also, each class has different subclasses, i.e. class 546 product, has 563 subclasses. The search for each core structure is extremely burdensome. 2. This case is a 371, therefore, its lack of unity is under US rules of 35 USC 121 and 372 due to this, instant application contains the following inventions or groups of inventions. The instant application is 371 and 35 USC 121. due to the reference, it is been shown to form a single general inventive concept under PCT Rule 13.1. The requirement is still deemed proper and is therefore made FINAL. Claims 1, 4-10, 12, 22-26, 31 in part of compounds of formula (I), wherein X is N, A is PNG media_image2.png 98 82 media_image2.png Greyscale are examined. Claims 32-33 and the remaining subject matter of claims 1, 4-10, 12, 22-26, 31 are withdrawn per 37 CFR 1.142(b). 2. Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims 22-23, 25 are rejected under 35 U.S.C. 112, first paragraph, because the specification, while being enabling for inhibition of GABAA α5, does not reasonably provide enablement for treating a disease related to the GABAA α5 receptor using the compound in claim 1. The specification does not enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and/or use the invention commensurate in scope with these claims. 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 1) the breadth of the claims, 2) the nature of the invention, 3) the state of the prior art, 4) the level of one of ordinary skill, 5) the level of predictability in the art, 6) the amount of direction provided by the inventor, 7) the existence of working examples, and 8) the quantity of experimentation needed to make or use the invention based on the content of the disclosure. In re Wands, 858 F.2d 731, 737, 8 USPQ2d 1400, 1404 (Fed. Cir. 1988). 1) The breadth of the claims. 2) The nature of the invention, 3) The state of the prior art, 4) The level of one of ordinary skill, 5) The level of predictability in the art, 6) The amount of direction provided by the inventor, 7) The existence of working examples, 8) The quantity of experimentation needed to make or use the invention based on the content of the disclosure. The nature of the invention: The instant invention is drawn to method for treating a disease related to the GABAA α5 receptor using the compound in claim 1. The state of the prior art: The state of the prior art: As indicated by the prior art, there is not any association between GABAA α5 inhibitors and treating a disease related to the GABAA α5 receptor. There is no guidance in the prior art that GABAA α5 inhibitor could be useful to treat a disease related to the GABAA α5 receptor. The predictability in the art: At present using GABAA α5 to treat a disease related to the GABAA α5 receptor is purely speculative. It is noted that the pharmaceutical art is unpredictable, requiring each embodiment to be individually assessed for physiological activity. In re Fisher, 427 F. 2d 833, 166 USPQ 18 (CCPA 1970) indicates that the more unpredictable an area is, the more specific enablement is necessary in order to satisfy the statute. They have not shown a nexus to treat diseases but have provided only reports in vitro which, absent a correlation to treat of diseases, are not sufficient to enable the invention. The level of the skill in the art: The level of skill in the art is high. Amount of guidance/working examples: Applicant provides no examples of the test compounds to inhibit GABAA α5. However, there is no guidance for using a therapeutically effective amount of a compound of Formula (I) to treat a disease related to GABAA α5 receptor. The breadth of the claims: The claims encompass a method for treating a disease related to GABAA α5 receptor. The quantity of experimentation needed: Since the guidance and teaching provided by the specification is insufficient for treating diseases associated with therapeutically effective amount of a compound of formula (I) is efficacious, one of ordinary skill in the art, even with high level of skill, is unable to use the instant compounds as claimed without undue experimentation. Taking all of the above into consideration, it is not seen where the instant claims 22-23, 25, for treating diseases associated with therapeutically effective amount of a compound of Formula (I) is efficacious, have been enabled by the instant specification. 3. Claims 22-25 Are rejected under 35 U.S.C. 112, first paragraph, because the specification, does not reasonably provide enablement for preventing a disease related to GABAA α5 receptor. The specification does not enable any person skilled in the art to which, or with which it is most nearly connected, to make and/or use the invention commensurate in scope with these claims. Applicants are not enabled for preventing any of these diseases. The only established prophylactics are vaccines not the compounds such as present here. In addition, it is presumed that “prevention” of the claimed diseases would require a method of identifying those individuals who will develop the claimed diseases before they exhibit symptoms. There is no evidence of record that would guide the skilled clinician to identify those who have the potential of becoming afflicted. “The factors to be considered [in making an enablement rejection] have been summarized as the quantity of experimentation necessary, the amount of direction or guidance presented, the presence or absence of working examples, the nature of the invention, the state of the prior art, the relative skill of those in that art, the predictability or unpredictability of the art, and the breadth of the claims”, In re Rainer, 146 USPQ 218 (1965); In re Colianni, 195 USPQ 150, Ex parte Formal, 230 USPQ 546. 1) As discussed above, preventing diseases requires identifying those patients who will acquire the disease before occurs. This would require extensive and potentially opened ended clinical research on healthy subjects. 2) The passage spanning line 31, page 39 to line 32, page 40 lists the diseases Applicant intend to treat. 3) There is no working example of such a preventive procedure in man or animal in the specification. 4) The claims rejected are drawn to medical treatment and are therefore physiological in nature. 5) The state of the art is that no general procedure is art-recognized for determining which patients generally will become afflicted before the fact. 6) The artisan using Applicants invention would be a Board Certified physician who specialized to treat diseases with an MD degree and several years of experience. Despite intensive efforts, pharmaceutical science has been unable to find a way of getting a compound to be effective for the prevention of disorder diseases generally. Under such circumstances, it is proper for the PTO to require evidence that such an unprecedented feat has actually been accomplished, In re Ferens, 163 USPQ 609. No such evidence has been presented in this case. The failure of skilled scientists to achieve a goal is substantial evidence that achieving such a goal is beyond the skill of practitioners in that art, Genentech vs. Novo Nordisk, 42 USPQ2nd 1001, 1006. This establishes that it is not reasonable to any agent to be able to prevent disorders generally. That is, the skill is so low that no compound effective generally against disorders has ever been found let alone one that can prevent such conditions. 7) It is well established that “the scope of enablement varies inversely with the degree of unpredictability of the factors involved", and physiological activity is generally considered to be an unpredictable factor. See In re Fisher, 427 F.2d 833, 839, 166 USPQ 18, 24 (CCPA 1970). 8) The claims broadly read on all patients, not just those undergoing therapy for the claimed diseases and on the multitude of compounds embraced by Formula (I). The Examiner suggests deletion of the word “prevention”. 4. Closest Art Subject Matter Closest art is Szabo et al., WO 2021191838, which includes the exemplified compound: PNG media_image3.png 310 758 media_image3.png Greyscale , which has different substitute in R2 position. Therefore, the claims are free of prior art. 5.
