Office Action

§102 §103 §112
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 Continued Examination Under 37 CFR 1.114 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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 3-17-2026 has been entered. The amendment filed on 3-24-2026 is acknowledged. Claims 1-4, 6 and 38-40 have been amended. Claims 41-42 have been added. Claims 1-6, 9-27 and 29-42 are pending. Claims 10-27 and 30-37 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected invention, there being no allowable generic or linking claim. Claims 1-6, 29 and 38-42 are currently under examination. Claim Rejections Withdrawn The rejection of claim 6 under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being, rendered vague and indefinite by the phrase "such as" is withdrawn in light of the amendment thereto. The rejection of claim 38 under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being rendered vague and indefinite by the use of the phrase “…the sequence identity is at least 75%..” is withdrawn in light of the amendment thereto. The rejection of claim 39 under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being rendered vague and indefinite by the use of the phrase “…the sequence identity is at least 80%..” is withdrawn in light of the amendment thereto. The rejection of claim 40 under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being rendered vague and indefinite by the use of the phrase “…the sequence identity is at least 90%.” is withdrawn in light of the amendment thereto. The rejection of claims 1-5, 29 and 38-40 under 35 U.S.C. 102(a)(1) as being anticipated by Rubenfield et al. (U.S. Patent 6,551,795 – IDS filed on 7-9-2024) is withdrawn in light of the amendment thereto. The rejection of claims 1-6, 29 and 38-40 under 35 U.S.C. 103 as being unpatentable over Rubenfield et al. (U.S. Patent 6,551,795 – IDS filed on 7-9-2024) is withdrawn in light of the amendment thereto. New Grounds of Rejection 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. Claim 42 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 applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Said claim is rendered vague and indefinite by the use of the phrase “…the amino acid sequence comprises at least one residue in SEQ ID NO:29…”. It is unclear which sequence recited in claim 1 said phrase is referring to. Consequently, it is impossible to determine the metes and bounds of the claimed invention. Conclusion No claim is allowed.
