Office Action

§112
DETAILED CORRESPONDENCE 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 . Status of Application The remarks filed on 3/27/2026 are acknowledged. Claims 1-16 are pending. Response to Amendments/Arguments The remarks filed 3/27/2026 have been fully considered and are persuasive in overcoming the previous art rejections, which are hereby withdrawn. The claims are free of the art. However, upon further consideration and interpretation of the claims, examiner identifies that independent claim 1 drawn to a cancer therapeutic agent, does not explicitly require a cancer therapeutic agent as an ingredient, and is unclear. Therefore, examiner is making a 35 USC 112(b) rejection. Since the new grounds of rejection are not necessitated by amendment, this action is made NON-FINAL. 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. Claims 1-16 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 pre-AIA the applicant regards as the invention. Claim 1 is drawn to a cancer therapeutic agent; however, claim 1 does not positively recite a cancer therapeutic agent as a required ingredient in the cancer therapeutic agent gel particle, which makes the claim indefinite. Examiner requests that the presence of a cancer therapeutic agent be explicitly recited for clarity. Claims 2-16 are included in the rejection because they do not correct for the defect of the claim from which they depend. Appropriate correction is required. Conclusion No claims are allowed.
