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 Continued Examination Under 37 CFR 1.114 1. A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 8/7/2026 has been entered. Status of the Claims 2. Claims 1-31 are the original claims filed on 5/8/2020.

This Office Action contains new grounds for rejection. Examiner’s Comments 3. A bona fide effort was made to contact the agent of record for this application to negotiate an allowance. The agent of record, Wyan-Ching Lee (agent registration no. 65,813), is not identified on 9/14/2026 at any of the telephone numbers listed of record: 617-862-6805 (Response of 8/7/2026, p. 19) and 202-429-6492 (USPTO Attorneys of Record for customer no. 21069). The Examiner of record contacted an Amgen operator at 805-447-1000 where Wyan-Ching Lee is not listed in their correspondence. The Examiner of record contacted Steptoe LLP (customer no. 21069) operator at 202-429-3000 where Wyan-Ching Lee is not listed in their correspondence. Priority 4. USAN 16/869,793, filed 05/08/2020, and having 4 RCE-type filing therein, claims foreign priority to EP19208417.6, filed 11/11/2019. Information Disclosure Statement 5. As of 9/14/2026, a total of seven (7) IDS are filed for this application: 8/11/2020; 12/1/2021; 9/26/2022; 1/16/2025; 6/9/2025; 4/6/2026; and 8/7/2026. The corresponding initialed and dated 1449 form is considered and of record. Withdrawal of Rejections Claim Rejections - 35 USC § 112(b) 6. The rejection of Claims 1-3, 5-11, 17-18, 21 and 24-41 under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite is moot for the canceled claim(s) and withdrawn for the pending claims. Claim 1 is amended to clarify the administration step(s) for at least a first cycle comprising at least three individual administrations of the antibody construct each at a dose of 800 ug/day to 12 mg/day, wherein each of said at least three individual administrations takes place on a single, separate day. Accordingly, the dependent claims comport with generic claim 1. Double Patenting 7. The rejection of Claims 1-3, 5-11, 17-18, 21 and 24-39 (and 40-41) on the ground of nonstatutory double patenting as being unpatentable over claims 1-23 of U.S. Patent No. 11352433 or claims 1-19 of U.S. Patent No. 10301391 in view of Cong et al (PTO 892 form)) is moot for the canceled claim and withdrawn for the pending claims. Applicants comments and the prosecution record combined with the amendments to generic claim 1 to clarify the subject of the invention having relapsed and/or refractory multiple myeloma with the administration step(s) for at least a first cycle comprising at least three individual administrations of the antibody construct each at a dose of 800 ug/day to 12 mg/day, wherein each of said at least three individual administrations takes place on a single, separate day overcomes the rejection. Withdrawal of Objection Claim Objections 8. The objection to Claims 5 and 40-41 because of informalities is withdrawn. a) Claim 5(b) is amended to recite “or b) two dose steps[,] from a first dose to a second dose, and a second dose to a third dose, during the first cycle.” b) The objection is withdrawn for claim 40 in view of the explanation provided in the response. New Grounds for Rejection 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. 9. Claim 42 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. Claim 42 recites the limitation "the target dose". There is insufficient antecedent basis for this limitation in the claim. Amended Claim 5 recites “a second target dose” and “a third target dose.” Claim 42 is indefinite as to the target the dose in claim 5. Conclusion 10. Claims 1-3, 5-11, 17-18, 21, 24-41 and 43-44 are allowed. 11. Any inquiry concerning this communication or earlier communications from the examiner should be directed to LYNN A.
