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 . Election/Restrictions Claims 1-13 withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected groups, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on 08/14/2026. Applicant’s election without traverse of Group III in the reply filed on 08/14/2026 is acknowledged. 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)(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(s) 14-21 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by DeHennis (USPN 20150182115-Cited by the Applicant). Regarding claim 14, DeHennis discloses a method for detecting glucose in a patient comprising: administering an indicator compound to the patient, the indicator compound ([0039], [0042], [0069]) comprising: a luminescent protein domain ([0039], [0042], [0069]); and a glucose binding protein domain ([0039], [0042], [0069]); wherein the indicator compound is configured to bind glucose via the glucose binding protein domain; wherein the indicator compound is configured to undergo a conformational change from a first conformation to a second conformation when glucose is bound by the glucose binding protein domain ([0039], [0042], [0069]); wherein, when in the second conformation, the indicator compound is configured to receive an excitation wavelength and to emit a luminescent signal ([0039], [0042], [0069]); wherein a contiguous 100 amino acid portion of the glucose binding protein domain shares 80% to 100% identity, homology, or similarity to a contiguous 100 amino acid portion of one of SEQ ID NOs: 2, 15, 122-221, or 824-1746 ([0039], [0042], [0069]). Regarding claim 15, quantifying a glucose level in the patient based on a change in luminescence of the indicator compound ([0039], [0042], [0069]). Regarding claim 16, the indicator compound is administered to the patient using a cell ([0039], [0042], [0069]). Regarding claim 17, the cell is autologous to the patient ([0039], [0042], [0069]). Regarding claim 18, the cell comprises DNA having a region that encodes the indicator compound ([0039], [0042], [0069]). Regarding claim 19, the cell is part of a skin graft received by the patient ([0039], [0042], [0069]). Regarding claim 20, the cell is a keratinocyte, melanocyte, Langerhans cell, Merkel cell, immune cell, macrophage, epithelial cell, or red blood cell ([0039], [0042], [0069]). Regarding claim 21, illuminating the indicator compound with light having a first maximum wavelength and detecting an emission of light at a second maximum wavelength ([0039], [0042], [0069]).
