Office Action

§102 §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 DETAILED ACTION Responsive to claim-set of 5/17/2023 & election entered 6/17/2026 Claims pending 1-20 Claims withdrawn 1-13 & 17-19 Claims currently under consideration 14-16,20 Priority This application has a actual filing date of 05/17/2023 and is a 371 of PCT/US21/59643 11/17/2021 PCT/US21/59643 has PRO 63/114,627 11/17/2020 Election/Restrictions Applicant’s species election of group III in the current reply filed is acknowledged. Because applicant did not distinctly and specifically point out any supposed errors in the restriction requirement, the election has been treated as an election without traverse (MPEP § 818.03(a)). Claims 1-13 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected invention, there being no allowable generic or linking claim. Election was made without traverse in the current reply. Applicant’s species election of a nanobody inhibitor of R. gnavus interacting with T cell protein CD7 in the current reply filed is acknowledged. Because applicant did not distinctly and specifically point out any supposed errors in the restriction requirement, the election has been treated as an election without traverse (MPEP § 818.03(a)). Claims 17-19 stand withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected species, there being no allowable generic or linking claim. Election was made without traverse in the current reply. Applicant's elected species was not found in the prior art, so the search was expanded to the extent set forth below. The requirement is still deemed proper and is therefore made FINAL. Claim Rejections - 35 USC § 102 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)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claim(s) 14-16,20 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Jensen et al (US AppPub 20230218682 – PTO 892 4/17/2026) As in present claims 14,15,16 and 20, Jensen et al teach throughout the reference and especially document claims 12,19 and paragraphs 0020 and/or 0070: a method of treating or preventing acne valgaris (an inflammatory disease) in a subject in need thereof, the method comprising administering Cas protein (a chemical compound) for inhibiting the interaction of a host protein (e.g. CD55) and a microbial cell (e.g. E. coli or Fusobacterium) to the subject, wherein the host protein and microbial cell are interacting partners selected from the group consisting of host protein and microbial cell interacting partners in present table 1. Claim Rejections - 35 USC § 112 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. 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. Claims 14-16,20 are 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. Claims 14 and 15 is/are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being incomplete for omitting essential structural cooperative relationships of elements, such omission amounting to a gap between the necessary structural connections or alternatively, as being incomplete for omitting essential steps, such omission amounting to a gap between the steps. See MPEP § 2172.01. The omitted structural cooperative relationships or omitted steps which render the metes and bounds uncertain are as follows. Each of claims 14 and 15 refer to a host protein and microbial cell interacting partner as set forth in table 1. However, such citation to table 1 is ambiguous, in so far as, for example, page 22 of the present published application specifies Ruminococcus gnavus strain NWP325 with strain ID RG74 interacts with CD7, but it is not clear if the claims intend to encompass entire biological species of Ruminococcus gnavus just strain NWP325 or even identified as RG74. In the context of claims 14 and 15, other entries in table 1 are likewise ambiguous. Moreover claims 14 and 15 are deemed incomplete in so far as they refer to table 1, whereas in accordance with MPEP 2173.05(s), the courts have held where possible, claims are to be complete in themselves. Incorporation by reference to a specific table "is permitted only in exceptional circumstances where there is no practical way to define the invention in words and where it is more concise to incorporate by reference than duplicating a drawing or table into the claim. Incorporation by reference is a necessity doctrine, not for applicant’s convenience." Ex parte Fressola, 27 USPQ2d 1608, 1609 (Bd. Pat. App. & Inter. 1993). Here, it is not necessary to refer to table 1, since it is not impractical to define the host proteins and microbial cells in the claims themselves. In accordance with MPEP 2173.02: If the language of the claim is such that a person of ordinary skill in the art could not interpret the metes and bounds of the claim so as to understand how to avoid infringement, a rejection of the claim under 35 U.S.C. 112, second paragraph, would be appropriate. See Morton Int ’l, Inc. v. Cardinal Chem. Co., 5 F.3d 1464, 1470, 28 USPQ2d 1190, 1195 (Fed. Cir. 1993). In so far as the metes and bounds of the offending claim(s) may not be interpreted properly for the reasons above, all dependent claims therefrom claim 14 are rejected as being indefinite as well. 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.
