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 Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Information Disclosure Statement The information disclosure statements (IDS) have been considered by the examiner. Status of applications, Amendments, and/or Claims The Response filed 20 July 2026 has been entered in full. Claims 3-4, 6, 9-16, 19-23 are currently pending. Claims 1-2, 5, 7-8, 17-18 are canceled. Claims 3-4, 6, 9-10, 13-16, 19-20 have been currently amended. Claims 21-23 are new. Claims 10-13, 19-20, 23 are withdrawn from consideration. Therefore, claims 3-4, 6, 9, 14-16, 21-22 are subject of this Office Action. Withdrawn Objections and/or Rejections The 35 USC § 112 (b) rejection to claims 1-4, 6, 9 as set forth at pp. 3-4 of the previous Office action (mailed 21 April 2026) is withdrawn in view of Applicant’s cancellation and/or amendments to claims (mailed 20 July 2026). The 35 USC § 112 (a) rejection to claims 1-9, 14-16 as set forth at pp. 4-15 of the previous Office action (mailed 21 April 2026) is withdrawn in view of Applicant’s cancellation and/or amendments to claims (mailed 20 July 2026). New Claim Rejections - 35 USC § 112 Necessitated by Amendment 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. Claim 6 rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as failing to set forth 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 6 recites the limitation of "the isolated humanized antibody" binding to Siglec-15 or an antigen binding fragment thereof, according to claim 3. However, claim 3 is not directed to a humanized antibody therefore there is a lack of antecedent basis for the limitation "the isolated humanized antibody". Therefore, there is insufficient antecedent basis for this limitation in the claim. ***** New Allowable Subject Matter The antibody binding to Siglec-15 or an antigen binding fragment there of comprising SEQ ID NOs: 1, 3, 5, 81, 9, 10 of claim 3 was searched and no prior art was found. Therefore, the antibody of claim 3 is allowable. Claim 3 and dependent claims 4, 9, 14-16, 21-22 are allowable because no prior art was found for the antibody of claim 3, and dependent claims 4, 9, 14-16, 21-22. Also, the antibody of claim 6 comprising the SEQ ID NOs: 53, 82 were searched, and no prior art was found. The embodiments of claim 6 mentioned above would otherwise be allowable. Response to Amendments Applicants’ arguments as they pertain to the rejections have been fully considered. In view of applicant’s cancellation and/or amendments to claims (mailed 20 July 2026), the rejections to claims 3-4, 9, 14-16, have been withdrawn by the examiner. Furthermore, since the Siglec-15 antibody of claim 3 is free of art, claim 3 and dependent claims 4, 9, 14-16 and new claims 21-22 are allowed. However, a 112(b) rejection to claim 6 is necessary because there is a lack of antecedent basis for the claim recitation "the isolated humanized antibody (..) according to claim 3”, because it is apparent that Claim 3 is not directed to a humanized antibody. Therefore, claim 6 is rejected for lack of antecedent basis. Conclusion Claims 3-4, 9, 14-16, 21-22 are allowed. THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
