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 Election/Restrictions Applicant’s election without traverse of Group I, claims 1-16 and species: SEQ ID NOs: 54, 33, 41, 44, 52, 20, 59, 60, Fab fragment, Alzheimer’s disease, and a method of treating a neurodegenerative disease in a human in the reply filed 03/03/2026 is acknowledged. Claims 17-19 and 24 are withdrawn from consideration pursuant to 37 CFR 1.142(b) as being drawn to nonelected inventions and species, there being no allowable generic or linking claims. Election was made in the reply filed 03/03/2026. Claims 1, 6-16, and new claims 25-26 are now under consideration in the instant Office Action. Withdrawn Rejections Rejections of claims 1-16 under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter are hereby withdrawn in view of amendments to the claims. Rejections of claims 1-16 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or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement are hereby withdrawn in view of amendments to the claims. Rejections of claims 1-16 under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, because the specification, while being enabling for binding to amyloid beta with the antibodies of Table 1, does not reasonably provide enablement for an antibody comprising for all the potential CDRs identities that can arise from the substitutions and variable percent identities in the instant claims and bind to amyloid beta are hereby withdrawn in view of amendments to the claims. New Rejections 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 1, 6-16, and 26 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 applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Instant claims 1 and 26 recite a list of amino acids followed by a sequence identity number in parenthesis. It is unclear whether the sequence identifiers that follow consist of the same list of amino acids. To obviate this rejection, Applicant should strike out the list of amino acids and retain the sequence identifiers or remove the parenthesis and replace them with commas in its place at all instances. Dependent claims 6-16 are included in this rejection because they fail to remedy the issue of the claim from which they depend. Conclusion Claim 25 is objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
