Office Action

§112
Detailed Office Action 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 . Continued Examination Under 37 CFR 1.114 2. 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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 01 April 2026 has been entered. Claim Rejections - 35 USC § 112 3. 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. 4. Claims 1-3, 5-16, and 18-21 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. Regarding the amendment to condition (1) within lines 6 and 7 of claim 1, the examiner has reviewed the specification, as originally filed, and has not found support for the scope of the amendment. While there is support for claiming that at least a diol-derived structure having 10 carbon atoms is present within the structure of the polycarbonate diol, there is insufficient support for extending this limitation to the polyol component. As the amendment is drafted, the position is taken that this limitation is not limited to the polycarbonate diol component. It is regretted that this issue was not raised during the interview of 04 February 2026. Withdrawal of Prior Art Rejections 5. The prior art rejections set forth within the Office action of 05 November 2025 have been withdrawn in view of applicants’ amendment. Conclusion 6. Any inquiry concerning this communication or earlier communications from the examiner should be directed to Rabon A Sergent whose telephone number is (571)272-1079. The examiner can normally be reached on Monday through Friday from 9:00 AM until 5:00 PM, ET.
