Office Action

§103
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 . Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Claims status: all claims are the same as presented last. Response to Arguments Applicant's arguments filed 08/06/2026 have been fully considered but they are not persuasive. Applicant argues in pg.6 of the remarks that Houck et al. do not teach “the reflective element be arranged on at least a part of one or both the lid element and the frame element”. Although, Houck et al. being the secondary reference and was not relied upon to teach the argued limitation. Houck et al. teach: element 118 of fig.3B is reflective (para. [0030]), element 120 of fig.1 is reflective (para. [0033]), element 122 of fig.1 is reflective (para. [0034]), element 116 of fig.1 is reflective (para. [0034]), element 308 of fig.3B is reflective (para. [0048]). These different elements of Houck et al. formed the interior walls of the sample cell; the interior walls of the cell of Houck et al. are reflective. Both Raczkowski et al. and Houck et al. use reflective interior walls. Modifying the apparatus of Raczkowski et al. with teachings of Houck et al. would have been obvious to one of ordinary skill in the art. Regarding the Drennen, III reference, applicant argues in pg.7 of the remarks that Drennen, III does not teach the claimed arrangement. Drennen, III was not used to teach the claimed arranged, but using the claimed material is known. Drennen, III is directed to a spectrometer of analyzing a sample in a cell, wherein the interior walls of the cell are coated with gold or aluminum. The combination of Raczkowski et al., Houck et al. and Drennen, III are not deficient in the rejection of claim 1. In response to applicant's argument made in pg.8 of remarks that it would not be obvious to combine the teachings of Raczkowski et al., Houck et al. and Drennen, III, the test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference; nor is it that the claimed invention must be expressly suggested in any one or all of the references. Rather, the test is what the combined teachings of the references would have suggested to those of ordinary skill in the art. See In re Keller, 642 F.2d 413, 208 USPQ 871 (CCPA 1981). Therefore, the rejection is maintained and made final. Claim Rejections - 35 USC § 103 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 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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claims 1-3, 5-6 are rejected under 35 U.S.C. 103 as being unpatentable over Raczkowski et al. (US 2022/0244104 A1; pub. Aug. 4, 2022) in view of Houck et al. (US 2021/0063241 A1; pub. Mar. 4, 2021) and further in view of Drennen, III (US 5,214,277; pub. May 25, 1993).
