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 . 37 C.F.R. § 1.114 A request for continued examination under 37 C.F.R. § 1.114, including the fee set forth in 37 C.F.R. § 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 C.F.R. § 1.114, and the fee set forth in 37 C.F.R. § 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 C.F.R. § 1.114. Status of the Claims Acknowledgement is hereby made of receipt and entry of the communication filed 18 February, 2026. Claims 1, 2, and 4-20 are pending in the instant application. Claims 11-20 stand withdrawn from further consideration by the Examiner, pursuant to 37 C.F.R. § 1.142(b), as being drawn to a non-elected invention. 35 U.S.C. § 112(a) The following is a quotation 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. Written Description The previous rejection of claims 1, 2, and 4-10 under 35 U.S.C. § 112(a), as failing to comply with the written description requirement, is hereby withdrawn in response to Applicant’s amendment and arguments. 35 U.S.C. § 112(b) The following is a quotation of 35 U.S.C. § 112(b): (b) CONCLUSION.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. Claims 1, 2, and 4-10 are 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. Two separate requirements are set forth under this statute: (1) the claims must set forth the subject matter that applicants regard as their invention; and (2) the claims must particularly point out and distinctly define the metes and bounds of the subject matter that will be protected by the patent grant. The claimed invention is directed toward an immunogenic composition comprising nucleic acids encoding an antigen of interest and IL-36 adjuvant. Immunogenicity is the ability of an antigen to induce an immune response (Pollard and Bijker, 2021). This recitation is vague and indefinite because the nucleic acids themselves would not necessarily be expected to be immunogenic. Amendment of the claim language to reference an immunizing composition comprising the nucleic acids of interest or a composition capable of inducing an immune response against an antigen comprising the nucleic acids of interest, would be acceptable. Correspondence Any inquiry concerning this communication should be directed to Jeffrey S. Parkin, Ph.D., whose telephone number is (571) 272-0908.
