Office Action

§112
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 Claims 12, 19, and 20 have been cancelled. Claims 1-11 and 13-18 are pending and under examination. Response to Amendment The amendment to the claims filed on 04/21/2026 does not comply with the requirements of 37 CFR 1.121(c) because the claims do not contain track changes to indicate what amendments have been made relative to the previously examined claim set filed 03/13/2025. Amendments to the claims filed on or after July 30, 2003 must comply with 37 CFR 1.121(c) which states: (c) Claims. Amendments to a claim must be made by rewriting the entire claim with all changes (e.g., additions and deletions) as indicated in this subsection, except when the claim is being canceled. Each amendment document that includes a change to an existing claim, cancellation of an existing claim or addition of a new claim, must include a complete listing of all claims ever presented, including the text of all pending and withdrawn claims, in the application. The claim listing, including the text of the claims, in the amendment document will serve to replace all prior versions of the claims, in the application. In the claim listing, the status of every claim must be indicated after its claim number by using one of the following identifiers in a parenthetical expression: (Original), (Currently amended), (Canceled), (Withdrawn), (Previously presented), (New), and (Not entered). (1) Claim listing. All of the claims presented in a claim listing shall be presented in ascending numerical order. Consecutive claims having the same status of “canceled” or “not entered” may be aggregated into one statement (e.g., Claims 1–5 (canceled)). The claim listing shall commence on a separate sheet of the amendment document and the sheet(s) that contain the text of any part of the claims shall not contain any other part of the amendment. (2) When claim text with markings is required. All claims being currently amended in an amendment paper shall be presented in the claim listing, indicate a status of “currently amended,” and be submitted with markings to indicate the changes that have been made relative to the immediate prior version of the claims. The text of any added subject matter must be shown by underlining the added text. The text of any deleted matter must be shown by strike-through except that double brackets placed before and after the deleted characters may be used to show deletion of five or fewer consecutive characters. The text of any deleted subject matter must be shown by being placed within double brackets if strike-through cannot be easily perceived. Only claims having the status of “currently amended,” or “withdrawn” if also being amended, shall include markings. If a withdrawn claim is currently amended, its status in the claim listing may be identified as “withdrawn—currently amended.” (3) When claim text in clean version is required. The text of all pending claims not being currently amended shall be presented in the claim listing in clean version, i.e., without any markings in the presentation of text. The presentation of a clean version of any claim having the status of “original,” “withdrawn” or “previously presented” will constitute an assertion that it has not been changed relative to the immediate prior version, except to omit markings that may have been present in the immediate prior version of the claims of the status of “withdrawn” or “previously presented.” Any claim added by amendment must be indicated with the status of “new” and presented in clean version, i.e., without any underlining. (4) When claim text shall not be presented; canceling a claim. (i) No claim text shall be presented for any claim in the claim listing with the status of “canceled” or “not entered.” (ii) Cancellation of a claim shall be effected by an instruction to cancel a particular claim number. Identifying the status of a claim in the claim listing as “canceled” will constitute an instruction to cancel the claim. (5) Reinstatement of previously canceled claim. A claim which was previously canceled may be reinstated only by adding the claim as a “new” claim with a new claim number. Claim Objections Claims 1, 2, 5, 8-11, and 13-16 are objected to because of the following informalities: the claims contain grammatically incorrect and convoluted language. See below for proposed claim amendments. Appropriate correction is required. Claim Rejections - 35 USC § 112(a) 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. (MAINTAINED REJECTION) Claims 1-11 and 13-18 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 claims contain 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 inventors, at the time the application was filed, had possession of the claimed invention. Claims 1-10 encompass: A recombinant fusion protein, comprising: a.) at least one first protein encoded by a nucleotide sequence selected from the group consisting of SEQ ID NO: 1, SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 4, SEQ ID NO: 5, SEQ ID NO: 6, and SEQ ID NO: 7; b.) at least one second protein encoded by a nucleotide sequence selected from the group consisting of SEQ ID NO: 8, SEQ ID NO: 9, SEQ ID NO: 10, SEQ ID NO: 11, SEQ ID NO: 12, and SEQ ID NO: 13; and c.) at least one linker peptide encoded by a nucleotide sequence selected from the group consisting of SEQ ID NO: 14, SEQ ID NO: 15, SEQ ID NO: 16, SEQ ID NO: 17, SEQ ID NO: 18, SEQ ID NO: 19, SEQ ID NO: 20, and SEQ ID NO: 21. Claims 11 and 13-18 encompass” A composition, comprising: a) at least one recombinant fusion protein; b) at least one non-fusion protein; and c) at least one additive, wherein the at least one recombinant fusion protein comprises: at least one first protein encoded by a nucleotide sequence selected from the group consisting of SEQ ID NO: 1, SEQ ID NO: 2, SEQ ID NO: 3. SEQ ID NO: 4, SEQ ID NO: 5 SEQ ID NO: 6, and SEQ ID NO:7; at least one second protein encoded by a nucleotide sequence selected from the group consisting of SEQ ID NO: 8, SEQ ID NO: 9, SEQ ID NO: 10, SEQ ID NO: 11, SEQ ID NO: 12, and SEQ ID NO: 13; and at least one linker peptide encoded by a nucleotide sequence selected from the group consisting of SEQ ID NO: 14, SEQ ID NO: 15, SEQ ID NO: 16, SEQ ID NO: 17, SEQ ID NO: 18, SEQ ID NO: 19, SEQ ID NO: 20, and SEQ ID NO: 21. Because of the phrase “a nucleotide sequence” instead of “the nucleotide sequence” the claims encompass any nucleotide that shares at least 3 contiguous nucleic acid residues with any of the sequences recited in the instant claims. MPEP 2163.05 II states “the written description requirement for a claimed genus may be satisfied through sufficient description of a representative number of species. A ‘representative number of species’ means that the species which are adequately described are representative of the entire genus. Thus, when there is substantial variation within the genus, one must describe a sufficient variety of species to reflect the variation within the genus. See AbbVie Deutschland GmbH & Co., KG v. Janssen Biotech, Inc., 759 F.3d 1285, 1300, 111 USPQ2d 1780, 1790 (Fed. Cir. 2014) (Claims directed to a functionally defined genus of antibodies were not supported by a disclosure that ‘only describe[d] one type of structurally similar antibodies’ that ‘are not representative of the full variety or scope of the genus.’). The disclosure of only one species encompassed within a genus adequately describes a claim directed to that genus only if the disclosure "indicates that the patentee has invented species sufficient to constitute the gen[us].’” There are no prior art references that teach a fusion protein comprising: at least a first protein encoded by a nucleotide sequence selected from the group consisting of SEQ ID NO:1, SEQ ID NO:2, SEQ ID NO:3, SEQ ID NO:4, SEQ ID NO:5, SEQ ID NO:6, or SEQ ID NO:7, at least a second protein encoded by a nucleotide sequence selected from the group consisting of SEQ ID NO:14, SEQ ID NO:15, SEQ ID NO:16, SEQ ID NO:17, SEQ ID NO:18, SEQ ID NO:19, SEQ ID NO:20, or SEQ ID NO:21, and at least one linker peptide encoded by a nucleotide sequence selected from the group consisting of SEQ ID NO:14, SEQ ID NO:15, SEQ ID NO:16, SEQ ID NO:17, SEQ ID NO:18, SEQ ID NO:19, SEQ ID NO:20, or SEQ ID NO:21. The specification does not disclose all claimed variants of SEQ ID NOs:1-21 that share only 3 contiguous nucleic acid residues with the instant sequences. Therefore, the disclosed species are not representative of the entire genus of nucleotide sequences as claimed. In summary, neither the instant specification, nor the prior art, discloses a structure-function relationship between conserved nucleotide residues and taste profile of the encoded protein. One of ordinary skill in the art cannot reasonably predict which residues of SEQ ID NOs:1-21 may be modified to generate fusion protein that may be used as a dairy substitute. Based on the instant disclosure, those skilled in the art would not conclude that the applicant was in possession of all claimed variants. To overcome the objections and rejection set forth in this Office action, Applicant may consider the following amendment, which has been drafted by the Examiner: Claim 1. A recombinant fusion protein, comprising: a.) at least athe nucleotide sequence selected from the group consisting of SEQ ID NO: 1, SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 4, SEQ ID NO: 5, SEQ ID NO: 6, and SEQ ID NO: 7; b.) at least athe nucleotide sequence selected from the group consisting of SEQ ID NO: 8, SEQ ID NO: 9, SEQ ID NO: 10, SEQ ID NO: 11, SEQ ID NO: 12, and SEQ ID NO: 13; and, c.) at least one linker peptide encoded by [[a]]the nucleotide sequence selected from the group consisting of SEQ ID NO: 14, SEQ ID NO: 15, SEQ ID NO: 16, SEQ ID NO: 17, SEQ ID NO: 18, SEQ ID NO: 19, SEQ ID NO: 20, and SEQ ID NO: 21. Claim 2. The recombinant fusion protein of claim 1, wherein the of, or plant origin Claim 5. The recombinant fusion protein of claim 1, wherein the, and a non-bovine protein, wherein the non-bovine protein is of Claim 8. The recombinant fusion protein of claim 1, wherein the at least one linker peptide fuses the Claim 9. The recombinant fusion protein of claim 1, wherein the orientations of the Claim 10. An expression vector Claim 11. A composition, comprising: a) at least one recombinant fusion protein; b) at least one non-fusion protein; and c) at least one additive, wherein the at least one recombinant fusion protein comprises: at least athe nucleotide sequence selected from the group consisting of SEQ ID NO: 1, SEQ ID NO: 2, SEQ ID NO: 3. SEQ ID NO: 4, SEQ ID NO: 5, SEQ ID NO: 6, and SEQ ID NO:7; at least athe nucleotide sequence selected from the group consisting of SEQ ID NO: 8, SEQ ID NO: 9, SEQ ID NO: 10, SEQ ID NO: 11, SEQ ID NO: 12, and SEQ ID NO: 13; and at least one linker peptide encoded by [[a]]the nucleotide sequence selected from the group consisting of SEQ ID NO: 14, SEQ ID NO: 15, SEQ ID NO: 16, SEQ ID NO: 17, SEQ ID NO: 18, SEQ ID NO: 19, SEQ ID NO: 20, and SEQ ID NO: 21. Claim 13. The composition of claim 11, wherein the at least one non-fusion protein is selected from the group consisting of a microbial protein, an animal protein, a plant protein,a recombinantly expressed protein. Claim 14. The composition of claim 11, wherein the Claim 15. The composition of claim 14, wherein the milk protein Claim 16. The composition of claim 11, wherein the wherein the non-bovine protein is a protein, an animal protein, a plant protein, or a recombinantly expressed protein. Conclusion THIS ACTION IS MADE FINAL.
