Claim Rejections - 35 USC § 112
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.
The following is a quotation of 35 U.S.C. 112(d):
(d) REFERENCE IN DEPENDENT FORMS.—Subject to subsection (e), a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers.
The following is a quotation of pre-AIA 35 U.S.C. 112, fourth paragraph:
Subject to the following paragraph [i.e., the fifth paragraph of pre-AIA 35 U.S.C. 112], a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers.
Claim(s) 10-16 are 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 pre-AIA the applicant regards as the invention. Claim(s) 10-16 claim both a device and the method. A single claim which claims both an apparatus and the method steps of using the apparatus is indefinite. Ex parte Lyell, 17 USPQ2d 1548 (Bd. Pat. App. & Inter. 1990). Such a claim is directed to neither a “process” nor a “machine,” but rather embraces or overlaps two different statutory classes of invention (MPEP § 2173.05(p)). Applicant may cancel the claim(s), amend the claim(s) to place the claim(s) in proper dependent form, rewrite the claim(s) in independent form, or present a sufficient showing that the dependent claim(s) complies with the statutory requirements.
Claim(s) 10-16 are rejected under 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, 4th paragraph, as being of improper dependent form for failing to further limit the subject matter of the claim upon which it depends, or for failing to include all the limitations of the claim upon which it depends. Claim(s) 10-16 are for a device that depend on a method claim 1. This constitutes an improper dependent claim. “if claim 1 recites a method of making a specified product, a claim to the product set forth in claim 1 would not be a proper dependent claim if the product can be made by a method other than that recited in the base method claim, and thus, does not include the limitations of the base claim” (MPEP 608.01(n)(III)). Applicant may cancel the claim(s), amend the claim(s) to place the claim(s) in proper dependent form, rewrite the claim(s) in independent form, or present a sufficient showing that the dependent claim(s) complies with the statutory requirements.
Appropriate correction is required.
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 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.

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 of this title, 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) 8 are rejected under 35 U.S.C. 103 as being unpatentable over Wang in view of Facer et al. (US 20030072549).
Regarding claim 8, Wang teaches in figure(s) 1-11 Method as claimed in claims 6,
Wang does not teach explicitly wherein calculating the dielectric parameters comprises the step of calculating a sample impedance assuming a reflection coefficient F at the sample interferences equivalent to the actual reflection scattering parameters.
However, Facer teaches in figure(s) 1-8 wherein calculating the dielectric parameters comprises the step of calculating a sample impedance assuming a reflection coefficient F at the sample interferences equivalent to the actual reflection scattering parameters (para. 14 - network analyzer that determines the sample impedance from transmission and reflectance parameters across the gap in the inner conductor in the frequency range of e.g., 45 MHz to 40 GHz).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Wang by having wherein calculating the dielectric parameters comprises the step of calculating a sample impedance assuming a reflection coefficient F at the sample interferences equivalent to the actual reflection scattering parameters as taught by Facer in order to provide derived measurements based on Scattering and dielectric parameters as evidenced by "A coplanar waveguide for use in dielectric spectroscopy of biological solution…the waveguide is coupled to a network or impedance analyzer by means of appropriate connectors and the response of the biological solution to the input signals is recorded…Microwave data at frequencies above 45 MHz are phase sensitive transmission and reflectance coefficients, also known as "S-parameters," that may be obtained using a Hewlett-Packard 8510C vector network analyzer, for example. The S-parameters can then be used to derive impedance data." (abstract, para. 43).

However, Ghasr teaches in figure(s) 1-9 wherein the sample holder (3) comprises a perimeter flange (10) (106; fig. 1) for connection to the transmission lines (5).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Wang by having wherein the sample holder (3) comprises a perimeter flange (10) for connection to the transmission lines (5) as taught by Ghasr in order to provide " an edge of flange 106, is more prominent for a conductor-backed dielectric sheet or layered composites because the combination of the flange and the conductor backing of the sample creates a parallel plate transmission line guiding the electromagnetic wave to the edges of the flange" (para. 42).
Claim(s) 15 are rejected under 35 U.S.C. 103 as being unpatentable over Wang in view of Obeng et al. (US 20220136967).
Regarding claim 15, Wang teaches in figure(s) 1-11 System as claimed in claim 14,

However, Seyama teaches in figure(s) 1-7 wherein the cavity (8) has an axial length ranging from 2 to 5 mm (para. 34 - h=2 mm and w=3 mm; figs. 1,4).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Wang by having wherein the cavity (8) has an axial length ranging from 2 to 5 mm as taught by Seyama in order to provide a matter of design choice as evidenced by "A dielectric spectrometer includes an apparatus main body including a dielectric and in which a flow channel is formed and a probe including a high frequency line."
