Office Action

§102
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 . Applicant’s election without traverse of Group I, claims 18-28 in the reply filed on 01/05/2026 is acknowledged. Claims 29-38 withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to nonelected inventions, there being no allowable generic or linking claim.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 01/05/2026. Claims 18-38 are pending. Claims 18-28 are being examined. Claims 29-38 are withdrawn from further consideration as being drawn to non-elected inventions. Allowable Subject Matter Claims 19-28 are 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. Claim Rejections - 35 USC § 102 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 (i.e., changing from AIA to pre-AIA ) 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. 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. Claim 18 is rejected under 35 U.S.C. 102(a)(1) as being anticipated by Shirley et al. (Shirley et al., “Metalation of 14H-Dibenso[a,h]-,7H-Dibenzo[c,h]-, and 14H-Dibenzo[a,c]phenothiazine with n-Butyllithium”, The Journal of Organic Chemistry, Vol. 27, No. 12, 1 December 1962, pages 4421-4424). Considering claim 18, Shirley teaches compounds with claimed formula (I) (Shirley, compounds III & XII).
