Office Action

§112
DETAILED ACTION Notice of Pre-AIA or AIA Status 1. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . 2. This action is in response to papers filed 7/27/2026. 3. Applicant’s election without traverse of Group I and antiPD1 or antigen binding fragment thereof in the reply filed on 11/18/2024 is acknowledged. 4. Claims 22-23, 25, 28-35, 38-39, 41-44 are pending. Claims 1-21,24,26-27,36-37,40 have been cancelled. 5. Claims 23, 25 and 41 are withdrawn as being drawn to a nonelected species or invention. 6. The following rejections for claims 22, 28-35,38-39,42-44 are newly applied as necessitated by amendment. 7. This action is FINAL. Withdrawn Rejections The 35 USC 112a and 35 USC 112b rejections made in the previous office action are withdrawn based upon amendments to the claims. Drawings 8. The drawings are objected to because figures 4A comprise wording that is too small to be legible Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Claim Rejections - 35 USC § 112 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. 9. Claims 22, 28-35,38-39,42-44 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. The claims are drawn to administering to the individual “not having an amplification of …wherein an amplification of GAL, TESMIN, CPT1A…”. Therefore this recitation includes “amplification” of one or any combination of the genes listed in the claims. This term is not defined in the specification. The reply asserts that the support for the amendments is provided in paragraph 125, Figures 4A and 4B and Example 5. Paragraph 125 appears to be towards administration of PD- antibody wherein “individual not having an amplification of chromosome 11q13”. However, this recitation of amplification does not provide support for any the genes individually or in combination associating with treatment. Example 5 provides CCND1 and FGF3 amplification (para 215). The specification asserts that these patients without amplification had longer survival, but this recitation does not provide a description of any of the genes or any combination of the genes. Further in figures 4A and 4B, none of these population types disclose all the genes are amplified and therefore the specification has not provided support for this recitation. 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. 11. Claims 22, 28-35,38-39,42-44 are 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. Claims 22, 28-35,38-39,42-44 are indefinite over the phrase “amplification”. Amplification is a relative term which renders the claim indefinite. The term “amplification” is not defined by the claim, the specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably apprised of the scope of the invention. In particular are there is no comprises step it is not clear which would be considered “amplified”. Furthermore it is not clear what is intended to be amplified. It is not clear if the claim is intending to encompass deletions, rearrangements, translocations, mRNA expression, or protein expression using the term “amplification”. Conclusion 19. No claims are allowed. 20. 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).
