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 . Election/Restrictions 2. Applicant’s election without traverse of Group 2, claims 8-19 in the reply filed on 4/14/2026 is acknowledged. Claims 11-14 and 17 are withdrawn from prosecution. Information Disclosure Statement 3. The information disclosure statement (IDS) submitted on 6/14/2023 was filed timely. The submission is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. Claim Rejections - 35 USC § 112 4. 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. 5. Claim 17 is rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. The term “including, but not limited to” that is an improper Markush group and should be corrected. Allowable Subject Matter 6. Claims 8-19 are allowed. 7. The following is an examiner’s statement of reasons for allowance: The prior art does not teach each and every element of the process of producing a biodegradable microcapsule with a liquid hydrophobic core and a shell where at least one polymer and a filler of a crystalline wax is formed by steps a) to e) having the required conditions. 8. Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee.
