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 .
Response to Arguments
Applicant's arguments filed 08/06/2026 have been fully considered but they are not persuasive. Applicant’s arguments, see pages 5-10, filed 08/06/2026 with respect to the rejection(s) of claim 1 under U.S.C. 103 have been fully considered and are persuasive. Therefore, the rejection has been withdrawn. A new ground(s) of rejection is necessitated by the amendment. The deficiencies of Efthimion in view of Dionigi are now met by Efthimion in view of Hartman. Applicant’s arguments with respect to claims 1 have been considered but are moot because the arguments do not apply to how the references are being used in the current rejection.
In response to applicant’s argument that there is no teaching, suggestion, or motivation to combine the references, the examiner recognizes that obviousness may be established by combining or modifying the teachings of the prior art to produce the claimed invention where there is some teaching, suggestion, or motivation to do so found either in the references themselves or in the knowledge generally available to one of ordinary skill in the art. See In re Fine, 837 F.2d 1071, 5 USPQ2d 1596 (Fed. Cir. 1988), In re Jones, 958 F.2d 347, 21 USPQ2d 1941 (Fed. Cir. 1992), and KSR International Co. v. Teleflex, Inc., 550 U.S. 398, 82 USPQ2d 1385 (2007). In this case,
Claim 1, Efthimion discloses an apparatus for gas identification (fig. 1a, 1b, measures metals in gas streams, col. 5, ln. 20-65), comprising: a plurality of re-entrant microwave cavities (fig. 1a,1b, resonant-high-intensity reentrant microwave cavity, col. 5, ln. 20-65), wherein each re-entrant microwave cavity (fig. 1a,1b, reentrant cavity 12, col. 5, ln. 20-65), comprises: a tubular body (see fig. 1a,1b) having an exterior wall, a top portion, and a bottom portion (see fig. 1a,1b); an inner conductor (fig. 1a,1b, coaxial center conductor 14, col. 5, ln. 20-23) positioned within the tubular body; a measurement conduit (fig. 1a, 1b, circular quartz tube 42, col. 5, ln. 51-54) positioned within the inner conductor and extending from the bottom portion to the top portion of the tubular body (see fig. 1a,1b); wherein the cavity entry is in connection with a first end of the measurement conduit (42) and formed to receive one or more gases from below the tubular body (fig. 1a,1b, gas stream 50 enters the cavity 12 through the quartz tube 42, col. 5, ln. 58-60); wherein the cavity exit is in connection with a second end of the measurement conduit (42) and formed to release the one or more gases (fig. 1a, 1b, flows into the plasma region. The gas then exits the cavity through a small hole on the opposite side wall, col. 3, ln. 4-9) from the tubular body (fig. 1a,1b, gas stream 50 then exits the cavity 12 through a small hole 46 in the bottom of the cavity 12, col. 5, ln. 62-63); and a high frequency connector attached with the exterior wall and configured to connect to a microwave source (fig. 1a, 1b, coaxial cable feed from the generator 34 microwave power to flow into the cavity 12, col. 5, ln. 41-56).
Efthimion does not disclose a low-loss dielectric filling material between the exterior wall and the inner conductor, wherein the low-loss dielectric filling material is Teflon, Rexolite®, or a crystal material; cavity exit is in connection with a second end of the measurement conduit and formed to release the one or more flowing produced gases; re-entrant microwave cavities positioned to be substantially aligned with a flow of produced gases from a well; a cavity entry formed proximate the bottom portion and a cavity exit formed proximate the top portion; formed to release the one or more flowing produced gases; wherein the microwave source is at least one vector network analyzer connected with a switch system configured to send a radio frequency signal at a specific time to one or more specific re-entrant microwave cavities of the plurality of re-entrant microwave cavities.
Hartman discloses a low-loss dielectric filling material (fig. 1A, 1B, Dielectric shell 36 is preferably formed by a high-Q dielectric such as polytetrafluoroethylene (PTFE, Teflon), col. 3, ln. 30-35) between the exterior wall and the inner conductor (fig. 1A, 1B, conductive shells 30, 32, col. 3, ln. 30-35), wherein the low-loss dielectric filling material is Teflon, Rexolite®, or a crystal material (fig. 1A, 1B, polytetrafluoroethylene (PTFE, Teflon), col. 3, ln. 30-35).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to provide resonator an outer cylindrical shell, and an inner shell space between the inner and outer shells may be filled by a dielectric, as taught in Hartman in modifying the apparatus of Efthimion. The motivation would be to allows high Q-factors, wide tuning ranges for given cavity sizes, and relatively homogeneous transverse magnetic fields (see Hartman: col. 2, ln. 15-20).
Parker discloses cavity exit (see fig. 1, pipe 70, par. [0045]) is in connection with a second end of the measurement conduit (see fig. 1, body 20 par. [0045]) and formed to release the one or more flowing produced gases (clm. 23); re-entrant microwave cavities (fig. 1, cavity resonator 10, par. [0045]) positioned to be substantially aligned with a flow of produced gases from a well (par. [0042]-[0046]) (clm. 1); a cavity entry cavities (see fig. 1, pipe 60, par. [0045]) formed proximate the bottom portion and a cavity exit (see fig. 1, pipe 70, par. [0045]) formed proximate the top portion; formed to release the one or more flowing produced gases (clm. 23).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to provide cavity having a fluid entrance and a fluid exit forming a fluid flow path through the cavity, as taught in Parker in modifying the apparatus of Efthimion. The motivation would be to detect properties of a flowing fluid (see Parker: par. [0001]).
Regarding "produced gases from a well" it has been held that a recitation with respect to the manner in which a claimed apparatus is intended to be employed does not differentiate the claimed apparatus from a prior art apparatus satisfying the claimed structural limitations. Ex parte Masham,2 USPQ2d 1647 (1987). Therefore, specifying that the re-entrant microwave cavity is intended to be used in the measurement of produced gases from a well does not differentiate the claimed apparatus from a prior art apparatus satisfying the claimed structural limitations.
Zhou discloses wherein the microwave source is at least one vector network analyzer (fig. 2, vector network analyzer 212, Specific implementation methods, 1st par.) connected with a switch system (fig. 2, 214 multi-channel switch matrix, Specific implementation methods, 1st par.) configured to send a radio frequency signal at a specific time to one or more specific re-entrant microwave cavities of the plurality of re-entrant microwave cavities (fig. 2, real-time controller also controls high-speed switching of the on or off states of switches in the multi-channel switch matrix and the multi-probe switch matrix, abs., Specific implementation methods, 7th par.).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to provide system comprising a real- time controller connected with a vector network analyzer, a multi-channel switch matrix, multiple probe switch matrix, as taught in Zhou in modifying the apparatus of Efthimion, Hartman and Parker. The motivation would be to reduce the testing time of an antenna test system (see Zhou: summary of the invention: 2nd par).
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.
Claim 1-4 and 6-20 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 applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Claim 1 contains the trademark/trade names Teflon and Rexolite®. Where a trademark or trade names Teflon and Rexolite®, which are subject to change by time, is used in a claim as a limitation to identify or describe a particular material or product, the claim does not comply with the requirements of 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph. See Ex parte Simpson, 218 USPQ 1020 (Bd. App. 1982). The claim scope is uncertain since the trademark or trade name cannot be used properly to identify any particular material or product. A trademark or trade name is used to identify a source of goods, and not the goods themselves. Thus, a trademark or trade name does not identify or describe the goods associated with the trademark or trade name. In the present case, the trademark/trade name is used to identify/describe a connector providing connection interface and, accordingly, the identification/description renders the claim to be indefinite.
