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 . DETAILED ACTION Claim Status Claims 1-11 are pending. Claims 2-7 and 9-11 have been amended. Claims 1-11 are being examined in this application. Claim Rejections - 35 USC § 112 The rejection of claim 11 under 35 USC 112(a) is withdrawn in view of the amendments to the claims. The rejection of claims 2 and 5 under 35 USC 112(b) is withdrawn in view of the amendments to the claims. The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—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 or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 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. This rejection has been modified. Claims 9-10 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, because the specification, while being enabling for the treatment of hepatic fibrosis, does not reasonably provide enablement for the treatment of every organ fibrosis. The specification does not enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to use the invention commensurate in scope with these claims. The MPEP states: “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) The breadth of the claims; (B) The nature of the invention; (C) The state of the prior art; (D) The level of one of ordinary skill; (E) The level of predictability in the art; (F) The amount of direction provided by the inventor; (G) The existence of working examples; and (H) The quantity of experimentation needed to make or use the invention based on the content of the disclosure.” (A) The breadth of the claims; and (B) The nature of the invention; The instant invention pertains to a method of treating organ fibrosis; wherein the method comprises administering the peptide compound of claim 1 to a subject. (C) The state of the prior art; Generally, the state of the art with respect to the treatment of fibrosis teaches that fibrosis is untreatable, and further teaches that so far, no drugs to stop or reverse fibrosis have won approval in the United States (see Leslie, Science Now, May 2012). (D) The level of one of ordinary skill; The skill of those skilled in the art is high. (E) The level of predictability in the art; The skilled artisan would view that the treatment of each and every organ fibrosis is highly unpredictable. (F) The amount of direction provided by the inventor; and (G) The existence of working examples; and (H) The quantity of experimentation needed to make or use the invention based on the content of the disclosure. The specification provides experimental results which illustrate that hepatic fibrosis can be treated with the claimed peptide compounds. However, the specification fails to provide scientific data and working embodiments with respect to showing the treatment of any other organ fibrosis. Note that lack of a working example, is a critical factor to be considered, especially in a case involving an unpredictable and undeveloped art. See MPEP 2164. The MPEP (2164.02) states that " The specification need not contain an example if the invention is otherwise disclosed in such manner that one skilled in the art will be able to practice it without an undue amount of experimentation. In re Borkowski, 422 F.2d 904, 908, 164 USPQ 642, 645 (CCPA 1970).” The MPEP further states that PNG media_image1.png 18 19 media_image1.png Greyscale “Lack of a working example, however, is a factor to be considered, especially in a case involving an unpredictable and undeveloped art.” Considering the state of the art as discussed above and the high unpredictability and the lack of guidance provided in the specification, one of ordinary skill in the art would be burdened with undue experimentation to make and use the invention as claimed. Response to Arguments Applicant’s arguments filed on 1/16/2026 have been fully considered but they are not persuasive. Applicant argues that the deletion of the terms “preventing” and “fibrotic conditions accompanying organ disease” overcome the examiner’s rejection. Applicant’s arguments are not persuasive because, as discussed above, the specification fails to provide scientific data and working embodiments with respect to showing the treatment of any organ fibrosis other than hepatic fibrosis. Furthermore, the Examiner submits the reference of Panos et al. (Panos et al., Am J Med. 1990 Apr;88(4):396-404), which teaches that patients with idiopathic pulmonary fibrosis (IPF) inevitably experience declines in functional status that are most frequently due to progressive pulmonary fibrosis. However, the cause of the clinical deterioration is often uncertain, and disease progression is difficult to distinguish from disease-associated complications or adverse effects of therapy (see abstract). Thus, if the cause is uncertain and the disease progression is difficult to distinguish, a method of treatment is also uncertain. Furthermore, considering the different etiologies of various organ fibrosis, and the lack of guidance provided in the specification, one of ordinary skill in the art would be burdened with undue experimentation to make and use the invention as claimed. For the reasons stated above the rejection is maintained. Allowable Subject Matter Claims 1-8 are allowed. Claim 11 is 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 THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
