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
2. The election without traverse filed 12/11/2025 in response to the Office Action of 10/22/2025 is acknowledged and has been entered.
Applicant has elected Group I, claims 1-11, drawn to an immunogen comprising:
an immunogenic fragment of a Plasmodium HAP2 paralog (HAP2p) protein; and
an immunogenic carrier operatively coupled to the peptide.
3. Claims 1-11, 13, 19, 22-27 and 29 are pending in the application. Claims 13, 19, 22-27 and 29 have been withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to nonelected inventions, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on 12/11/2025.
Claims 1-11 are currently under prosecution.
Priority
5. Applicant’s claim under 35 U.S.C. §§ 119(e) and/or 365(c) for benefit of the earlier filing date of applications, is acknowledged.
Claim Rejections - 35 USC § 112
6. 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.
7. 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.
8. Claim 1 is 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 recites the limitation "the peptide" in line 3. There is insufficient antecedent basis for this limitation in the claim.
Claim Rejections - 35 USC § 112
9. 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.
10. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), first paragraph:
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.
11. Claims 3-9 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 pre-AIA the inventor(s), at the time the application was filed, had possession of the claimed invention.
This is a “written description” rejection.
The considerations that are made in determining whether a claimed invention is supported by an adequate written description are outlined by the published Guidelines for Examination of Patent Applications Under the 35 U.S.C. 112, para. 1, ``Written Description'' Requirement (Federal Register; Vol. 66, No. 4, January 5, 2001; The 2015 Written Description Workshop materials; hereinafter “Guidelines”).
These guidelines state that rejection of a claim for lack of written description, where the claim recites the language of an original claim should be rare. Nevertheless, these guidelines further state, “the issue of a lack of written description may arise even for an original claim when an aspect of the claimed invention has not been described with sufficient particularity such that one skilled in the art would recognize that the applicant has possession of the claimed invention” (Id. at 1105). The “Guidelines” continue:
The claimed invention as a whole may not be adequately described if the claims require an essential or critical feature which is not adequately described in the specification and which is not conventional in the art or known to one of ordinary skill in the art. This problem may arise where an invention is described solely in terms of a method of its making coupled with its function and there is no described or art-recognized correlation or relationship between the structure of the invention and its function. A lack of adequate written description issue also arises if the knowledge and level of skill in the art would not permit one skilled in the art to immediately envisage the product claimed from the disclosed process.
With further regard to the proposition that, as original claims, the claims themselves provide in haec verba support sufficient to satisfy the written description requirement, the Federal Circuit has explained that in ipsis verbis support for the claims in the specification does not per se establish compliance with the written description requirement:
Even if a claim is supported by the specification, the language of the specification, to the extent possible, must describe the claimed invention so that one skilled in the art can recognize what is claimed. The appearance of mere indistinct words in a specification or a claim, even an original claim, does not necessarily satisfy that requirement. The disclosure must allow one skilled in the art to visualize or recognize the identity of the subject matter purportedly described. Eli Lilly, 119 F.3d at 1568, 43 USPQ2d at 1406.
Regents of the University of California v. Eli Lilly & Co., 119 F.3d 1559, 43 USPQ2d 1398 (Fed. Cir. 1997). See also: University of Rochester v. G.D. Searle & Co., 69 USPQ2d 1886 1892 (CA FC 2004).
Thus, an original claim may provide written description for itself, but it must still be an adequate written description, which establishes that the inventor was in possession of the invention.
The claims 3-8 are herein drawn to a peptide comprising a sequence with at least 80%, 85%, 90%, or 95% sequence identity to SEQ ID NOs: 2-4.
Thus, the claim is drawn to a genus of peptides that has at least 80%, 85%, 90%, or 95% sequence identity to SEQ ID NOs: 2-4.
The claim 9 is drawn to a sequence corresponding to SEQ ID NO: 4, it includes any fragment of SEQ ID NO: 4.
Although the specification teaches SEQ ID NOs: 2-4 (see [0102-0104] of published application); however, the specification does not teach that a peptide at least 80%, 85%, 90%, or 95% identical to SEQ ID NOs: 2-4, or a fragment of SEQ ID NO: 4 would have or retain the activity or function of SEQ ID NOs: 2-4.
Given the fact that the claims are drawn to a genus of peptides that has at least 80%, 85%, 90%, or 95% identical to SEQ ID NOs: 2-4, which have no particular function or activity, there is no correlation between any one particularly identifying structural feature and any one particularly identifying functional feature. Consequently, it is submitted that the skilled artisan could not immediately envision, recognize or distinguish at least a substantial number of the genus of peptides that has at least 80%, 85%, 90%, or 95% identical to SEQ ID NOs: 2-4 to which the claim is directed.
Although the specification teaches SEQ ID NOs: 2-4, SEQ ID NOs: 2-4 are not reasonably representative of the genus of peptides that has at least 80%, 85%, 90%, or 95% identical to SEQ ID NOs: 2-4. This is largely because each peptide that has at least 80%, 85%, 90%, or 95% identical to SEQ ID NOs: 2-4 has substantially varying structure and need not have any particular function or activity.
Guidelines states, “[p]ossession may be shown in a variety of ways including description of an actual reduction to practice, or by showing the invention was ‘ready for patenting’ such as by disclosure of drawings or structural chemical formulas that show that the invention was complete, or by describing distinguishing identifying characteristics sufficient to show that the applicant was in possession of the claimed invention” (Id. at 1104). “Guidelines” further states, “[f]or inventions in an unpredictable art, adequate written description of a genus which embraces widely variant species cannot be achieved by disclosing only one species within the genus” (Id. at 1106); accordingly, it follows that an adequate written description of a genus cannot be achieved in the absence of a disclosure of at least one species within the genus. Moreover, because the claims encompass a genus of peptides that has at least 80%, 85%, 90%, or 95% identical to SEQ ID NOs: 2-4, which vary both structurally and functionally, an adequate written description of the claimed invention must include sufficient description of at least a representative number of species by actual reduction to practice, reduction to drawings, or by disclosure of relevant, identifying characteristics sufficient to show that Applicant was in possession of the claimed genus. In this instance, factual evidence of an actual reduction to practice has not been disclosed by Applicant in the specification; Applicant has not shown the invention was “ready for patenting” by disclosure of drawings or structural chemical formulas that show that the invention was complete; and Applicant has not described distinguishing identifying characteristics sufficient to show that Applicant was in possession of the claimed invention at the time the application was filed.
Thus, it is submitted that the instant claims, and the disclosure describing the claimed subject matter, fails to satisfy the written description requirement set forth under 35 U.S.C. § 112, first paragraph.
12. In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
Claim Rejections - 35 USC § 102
13. The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention.
14. Claims 1-2 and 10-11 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Angrisano et al. (Cell Reports, December 5, 2017, Vol. 21, pp 2868-2878, IDS).
Claims 1-2 and 10-11 are herein drawn to an immunogen comprising:
an immunogenic fragment of a Plasmodium HAP2 paralog (HAP2p) protein; and
an immunogenic carrier operatively coupled to the peptide.
Angrisano et al. teach that Plasmodium falciparum (Pf) peptide regions of HAP2 were produced and C-terminally fused to carrier protein, KLH (keyhole limpet hemocyanin); see entire document, e.g., first paragraph of left col. on page 2876, last paragraph of left col. on page 2870.
For claim 11, Angrisano et al. teach that Pf-HAP2-KLH peptide was mixed with TiterMax Gold Adjuvant; see paragraph 3 of left col. on page 2876.
