Office Action

§112
DETAILED ACTION 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 . 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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 08/05/2026 has been entered. Claims 1, 5, 12, 16, 19, 26, and 31 have been amended. Claims 1, 3-5, 8, 10, 12-14, 16, 18, 19, 22, 24, 26, 27, 28, 30 and 31 are pending are pending and under consideration. The rejection of claims 1, 3-5, 8, 10, 12-14, 16, 18, 22, 24, 26, 27, 28, 30 and 31 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or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention is withdrawn in light of applicant’s amendments. The rejection of claims 1, 3-5, 8, 10, 12-14, 16, 18, 22, 24, 26, 27, 28, 30 and 31 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112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement is withdrawn in light of applicant’s amendment deleting “reduced fragmentation” from claims 1, 16 and 31. 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 24 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. Claim 24, drawn to a composition of claim 16, is vague and indefinite in the recitation of the alternative embodiment of the TABi are autologous, allogenic or xenogenic. The descriptions of autologous, allogenic or xenogenic are relative terms which have no meaning when applied to an isolated composition. The terms autologous, allogenic or xenogenic can be used in reference to a host receiving the TABi in a method claim. Claims 4 and 30 are vague and indefinite in the recitation of “depending on the CTL proliferation measured” which is subjective. Section 2171 of the M.P.E.P. states: Two separate requirements are set forth in 35 U.S.C. 112(b) and pre-AIA 35 U.S.C. 112, second paragraph, namely that: (A) the claims must set forth the subject matter that the inventor or a joint inventor regards as the invention; and (B) the claims must particularly point out and distinctly define the metes and bounds of the subject matter to be protected by the patent grant. The first requirement is a subjective one because it is dependent on what the inventor or a joint inventor for a patent regards as his or her invention. Note that although pre-AIA 35 U.S.C. 112, second paragraph, uses the phrase "which applicant regards as his invention," pre-AIA 37 CFR 1.41(a) provides that a patent is applied for in the name or names of the actual inventor or inventors. The second requirement is an objective one because it is not dependent on the views of the inventor or any particular individual, but is evaluated in the context of whether the claim is definite — i.e., whether the scope of the claim is clear to a hypothetical person possessing the ordinary level of skill in the pertinent art In the instant case, it is unclear what applicant intends as a threshold for the in vitro CTL proliferation deemed sufficient to administer the TABi to the subject. Claims 4, 24 and 30 are rejected. Claims 1, 3, 5, 8, 10, 12-14, 16, 18, 19, 22, 26, 27, 28, and 31 are allowed.
