DETAILED ACTION The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claim(s) 1-18 are rejected under 35 U.S.C. 102(a1). Claim(s) 19-20 are rejected under 35 U.S.C. 103. 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) 1-18 are rejected under 35 U.S.C. 102(a1) as being anticipated by WO 2024/028482 to Jourdainne et al. (provided by applicant). In regards to claims 1-18, Jourdainne discloses and shows in Figures 1-7, an attachment (100) for an optical analysis system (21) that emits an excitation light toward a sample (120) (Figure 1) (pg. 6, par. 1-2), the attachment including: a reflective surface (121) positioned to reflect light from the sample toward a probe of the optical analysis system (Figures 3a-b, 5) (pg. 3, par. 1-2;

pg. 4, par. 1, 3; pg. 8, par. 1; wherein the probe end is disposed with a bioreactor, such that a fluid or material (applicant’s vessel) may flow through a plurality of openings in the cap, and allow the presence of molecules (applicant’s sample) to be detected); [claim 18] further comprising computer readable instructions stored in a memory and a processor, by executing the computer readable instructions in the processor, the optical analysis system is configured to generate a spectrum of the light directed to the light analyzer (pg. 1, par. 2-3; wherein Raman spectroscopy is performed and displayed) (Figures 6a-b). Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claim(s) 19 is rejected under 35 U.S.C. 103 as being unpatentable over Jourdainne, in view of US Publication 2023/0236128 to Churchwell et al. In regards to claim 19, Jourdainne discloses and shows the Raman spectroscopy system: [claim 19] wherein the sample is in a bioreactor and further comprising computer readable instructions stored in a memory and a processor, by executing the computer readable instructions in the processor, the optical analysis system is configured to measure the backscattered light and the frontscattered light at a first time point and at a later, second, time point and determine the presence of molecules based on the measurement at the first time point and the second time point (Figures 1, 3a-b, 5, 7a-c) (pg. 1, par. 1-3; pg. 3, par. 1-2; pg. 4, par. 1, 3; pg. 8, par. 1; wherein the probe end is disposed with a bioreactor, such that a fluid or material (applicant’s vessel) may flow through a plurality of openings in the cap, and allow the presence of molecules to be detected). Jourdainne differs from the limitations in that it is silent to the system and method for determining a cell density. However, Churchwell teaches and shows a Raman spectroscopy system, wherein Raman spectroscopy is utilized for a variety of molecular measurements, including determining cell density (par. 4). Therefore, it would have been obvious to one of ordinary skill in the art at the time of the effective filing date of the invention, to modify Jourdainne to include the cell density measurements discussed above for the advantage of rapidly and accurately performing a complete sample analysis, with a reasonable expectation of success. Claim(s) 20 is rejected under 35 U.S.C. 103 as being unpatentable over Jourdainne. In regards to claim 20, Jourdainne discloses and shows the Raman spectroscopy system: wherein the reflective cap (121) may enhance the received signal by a factor of 2 to 100 (pg. 3, par. 1), which may lead to better measurement consistency and controlled tolerances (pg. 13, par. 1); and wherein the cap may be removed to “clean or replace” (pg. 9, par. 1). Jourdainne differs from the limitations in that it is silent to the Raman spectroscopy system further comprising: determining a status of the reflective surface by comparing the measurements at the first time point and the second time point. However, one of ordinary skill in the art would recognize a drop or significant change in the intensity of the obtained spectral measurments, as an indication that the reflective surface needs to be cleaned or replaced. Further, the degradation of optical components is well-known to those of ordinary skill in the art. Therefore, it would have been obvious to one of ordinary skill in the art at the time of the effective filing date of the invention, to modify Jourdainne to include determining a status of the reflective mirror as discussed above for the advantages of maintaining an enhanced spectral signal, and determining if an optical element needs to be cleaned or replaced, with a reasonable expectation of success.
