The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
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 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.
Claims 26, 28, 29 and 31-34 are rejected under 35 U.S.C. 103 as being unpatentable over U.S. Patent 5,495,769 issued to Broden et al. (“Broden”) in view of U.S. Patent 9,234,776 issued to Strei (“Strei”), U.S. Patent Application Publication 2018/0106648 by Eastoe et al. (“Eastoe”), U.S. Patent 6,267,010 issued to Hatanaka et al. (“Hatanaka”), JP 2015-038841 by Hirose (“Hirose”), U.S. Patent 8,033,175 issued to Sundet et al. (“Sundet”), U.S. Patent 7,441,461 issued to Muth et al. (“Muth”) and CN 205898203 by Jiang et al. (“Jiang”).
As for claim 26, Broden discloses a multivariable transmitter for measuring multiple process fluid variables (Fig. 1), the multivariable transmitter comprising:
a process fluid conduit (4), the process fluid conduit having first and second process fluid penetrations (implicitly provided to sense differential pressure; col. 3,lines 13-15),
a first pressure sensor (52) operably coupled to the first process fluid penetration;
a temperature probe (8, 10) having a temperature sensor (Broden: 8) therein, the temperature sensor (8) being coupled to the measurement circuitry (Broden: 57, 58-64, 72, 80) to provide an indication of process fluid temperature;
a housing (14, 16);
measurement circuitry (57, 58-64, 72, 80) operably coupled to the first pressure sensor (52) disposed within the housing (col. 3, lines 59-61 and col. 4, lines 41-43).
Broden does not explicitly disclose that the process fluid conduit and the housing is constructed from a material suitable for exposure to saltwater.
However, Strei discloses a material suitable (col. 2, line 64 - col. 3, line 9) for exposure to saltwater.
It would have been obvious for one having ordinary skill in the art before the effective filing date of the present application to modify the process fluid conduit and housing of Broden to be constructed of the material as disclosed by Strei in order ensure that the conduit and housing will not corrode or degrade in salt water (Strei: col. 2, lines 61-64).
Broden as modified by Strei does not disclose that the process fluid conduit has a second pressure sensor operably coupled to the second process fluid penetration. Broden discloses that line pressure (via first pressure sensor 52) and differential pressure are measured, and that the differential pressure may be measured using a venturi tube (Broden: col. 3, lines 13-20), but Broden does not specifically disclose a second pressure sensor arranged to perform these measurements in conjunction with a first pressure sensor.
However, Eastoe discloses a second pressure sensor (22, 52) operably coupled to a second process fluid penetration (12), along with a first pressure sensor (21, 51) operably coupled to a first process fluid penetration (11). Eastoe discloses that the first and second pressure sensors are used to measure line pressure and differential pressure (paragraphs [0058] and [0059]), and that the differential pressure is measured using a venturi tube (paragraph [0046]).
Because Broden and Eastoe both disclose structures for measuring line pressure and differential pressure with a venturi tube, it would have been obvious for one having ordinary skill in the art before the effective filing date of the present application to substitute the first and second pressure sensors and venturi tube of Eastoe for the differential pressure sensor and line pressure sensor of Broden to achieve the predictable result of providing structures that measure line pressure and differential pressure.
Broden as modified by Strei and Eastoe discloses a subsea (Strei: col. 2, line 64 - col. 3, line 9) multivariable transmitter for measuring multiple process fluid variables (Broden: Fig. 1), the multivariable transmitter comprising:
a subsea (Strei: col. 2, line 64 - col. 3, line 9) process fluid conduit (Broden: 4 and Eastoe: 101) constructed from a material (Strei: col. 2, line 64 - col. 3, line 9) suitable for exposure to saltwater, the process fluid conduit (Eastoe: 101) having a first internal diameter proximate the first process fluid penetration (Eastoe: at 11; see Fig. 1) and a second internal diameter proximate the second process fluid penetration (Eastoe: at 12; see Fig. 1), wherein the first and second internal diameters are different (Eastoe: see Fig. 1);
a first pressure sensor (Eastoe: 21, 51) operably coupled to a first process fluid penetration (Eastoe: 11) via a first remote seal (Eastoe: paragraph [0056]);
a second pressure sensor (Eastoe: 22, 52) operably coupled to a second process fluid penetration (Eastoe: 12);
a housing (Broden: 16) suitable for exposure to saltwater (Strei: col. 2, line 64 -col. 3, line 9);
measurement circuitry (Broden: 57, 58-64, 72, 80 and Eastoe: 50) operably coupled to the first pressure sensor (Broden: 52 and Eastoe: 21, 51) and the second pressure sensor (Eastoe: 22, 52); and
a temperature probe (Broden: 8, 10) mounted to the subsea process conduit (Broden: see Fig. 1), the temperature probe being spaced form the first and second process fluid penetrations (Broden: see Fig. 1 and Eastoe: see Fig. 1), the temperature probe having a temperature sensor (Broden: 8) therein, the temperature sensor (Broden: 8) being coupled to the measurement circuitry (Broden: 57, 58-64, 72, 80) to provide an indication of process fluid temperature.
Broden as modified by Strei and Eastoe does not disclose that the temperature probe is mounted to the first remote seal.
However, Hatanaka discloses a temperature probe (20) that is mounted to a first remote seal (12).
It would have been obvious for one having ordinary skill in the art before the effective filing date of the present application to modify the temperature probe of Broden, Strei and Eastoe to be mounted to a first remote seal as disclosed by Hatanaka in order to simplify the process of attaching sensors to the conduit (Hatanaka: Abstract).
Although Broden as modified by Strei, Eastoe and Hatanaka discloses that the temperature probe (Broden: 8, 10 and Hatanaka: 20) has cabling (Broden: 10 and Hatanaka: 23), Broden as modified by Strei, Eastoe and Hatanaka does not disclose that the temperature probe has an outer surface constructed from metal suitable for exposure to the saltwater.
However, Hirose discloses cabling (1E; Fig. 4) that has an outer surface (20E) constructed from metal suitable for exposure to the saltwater (Embodiment 5).
It would have been obvious for one having ordinary skill in the art before the effective filing date of the present application to modify the cabling of the temperature probe of Broden, Strei, Eastoe and Hatanaka to have an outer surface constructed from metal as disclosed by Hirose in order to protect the cabling when it is used underwater (Hirose: Abstract and Embodiment 5).
Broden as modified by Strei, Eastoe, Hatanaka and Hirose does not explicitly disclose that the multivariable transmitter is configured to provide an indication of line pressure, differential pressure, and temperature.
However, Sundet discloses a multivariable transmitter (10) that is configured to provide an indication of line pressure, differential pressure, and temperature (see step 416).
It would have been obvious for one having ordinary skill in the art before the effective filing date of the present application to modify the multivariable transmitter of Broden, Strei, Eastoe, Hatanaka and Hirose to provide an indication of line pressure, differential pressure, and temperature as disclosed by Sundet in order to allow a user to monitor the line pressure, differential pressure, and temperature of the process fluid.
Broden as modified by Strei, Eastoe, Hatanaka, Hirose and Sundet does not disclose that the outer surface of the temperature probe is welded to the housing.
However, Muth discloses that an outer surface of a temperature probe is welded to a housing (col. 2, lines 6-9).
It would have been obvious for one having ordinary skill in the art before the effective filing date of the present application to modify the outer surface of the temperature probe of Broden, Strei, Eastoe, Hatanaka, Hirose and Sundet to be welded as disclosed by Muth in order to provide a connection that is explosion-protected (Muth: col. 2, lines 6-9).
Broden as modified by Strei, Eastoe, Hatanaka, Hirose, Sundet and Muth does not disclose that the temperature probe is mounted within a blind hole of the subsea process conduit.
However, Jiang discloses a temperature probe (9) that is mounted within a blind hole (10) of a process conduit (1).
It would have been obvious for one having ordinary skill in the art before the effective filing date of the present application to modify the temperature probe of Broden, Strei, Eastoe, Hatanaka, Hirose and Sundet and Muth to be mounted in a blind hole as disclosed by Jiang in order to ensure better heat conduction and a better heat measurement (Jiang: see the paragraph beginning “As shown in Fig. 1 …”).
As for claim 28, Broden as modified by Strei, Eastoe, Hatanaka, Hirose, Sundet, Muth and Jiang discloses that the second pressure sensor is operably coupled to the second process fluid penetration via a second remote seal (Eastoe: paragraph [0056]).

As for claim 31, Broden as modified by Strei, Eastoe, Hatanaka, Hirose, Sundet, Muth and Jiang discloses the multivariable transmitter of claim 26 (see the rejection of claim 26 above).
Broden as modified by Strei, Eastoe, Hatanaka, Hirose, Sundet, Muth and Jiang does not disclose a third pressure transmitter as recited.
However, Eastoe discloses a third pressure sensor (31) coupled to a third process fluid penetration (at 13) in a process fluid conduit, the third process fluid penetration being disposed opposite one of the first (at 11) and second process fluid penetrations (see Fig. 1). Easton discloses that third (31) and fourth pressure (32) sensors, and an additional temperature sensor (33) are provided to provide redundancy (Easton: paragraph [0023]).
It would have been obvious for one having ordinary skill in the art before the effective filing date of the present application to further modify the multivariable transmitter of Broden, Strei, Eastoe, Hatanaka, Hirose, Sundet, Muth and Jiang to include a third pressure sensor along with a fourth pressure sensor and an additional temperature sensor as disclosed by Easton, in order to provide redundancy (Easton: paragraph [0023]).
As for claim 32, Broden as modified by Strei, Eastoe, Hatanaka, Hirose, Sundet, Muth and Jiang discloses a fourth pressure sensor (Eastoe: 32) coupled to a fourth process fluid penetration (Eastoe: at 14), the fourth process fluid penetration being disposed opposite the other (Eastoe: at 12) of the first and second process fluid penetrations (Eastoe: see Fig. 1).

However, Hashemian discloses an RTD element that is a dual element type RTD (see Fig. 2).
It would have been obvious for one having ordinary skill in the art before the effective filing date of the present application to modify the RTD element of Broden, Strei, Eastoe, Hatanaka, Hirose, Sundet and Muth to be a dual element type as disclosed by Hashemian in order to maintain diversity while increasing redundancy in measuring an environment’s temperature (Hashemian: col. 4, line 11-15).
Claims 36, 39 and 44 are rejected under 35 U.S.C. 103 as being unpatentable over U.S. Patent 5,495,769 issued to Broden et al. (“Broden”) in view of U.S. Patent 9,234,776 issued to Strei (“Strei”), U.S. Patent Application Publication 2018/0106648 by Eastoe et al. (“Eastoe”), JP 2015-038841 by Hirose (“Hirose”), U.S. Patent 4,407,065 issued to Gray (“Gray”), CN 205898203 by Jiang et al. (“Jiang”) and U.S. Patent 7,441,461 issued to Muth et al. (“Muth”).

Broden does not explicitly disclose that the process fluid conduit is constructed from a material suitable for exposure to saltwater.
However, Strei discloses a material suitable (col. 2, line 64 - col. 3, line 9) for exposure to saltwater.
It would have been obvious for one having ordinary skill in the art before the effective filing date of the present application to modify the process fluid conduit of Broden to be constructed of the material as disclosed by Strei in order ensure that the conduit will not corrode or degrade in salt water (Strei: col. 2, lines 61-64).
Broden as modified by Strei does not disclose that the process fluid conduit has a second pressure sensor operably coupled to the second process fluid penetration. Broden discloses that line pressure (via first pressure sensor 52) and differential pressure are measured, and that the differential pressure may be measured using a venturi tube (Broden: col. 3, lines 13-20), but Broden does not specifically disclose a second pressure sensor arranged to perform these measurements in conjunction with a first pressure sensor.
However, Eastoe discloses a second pressure sensor (22, 52) operably coupled to a second process fluid penetration (12), along with a first pressure sensor (21, 51) operably coupled to a first process fluid penetration (11). Eastoe discloses that the first and second pressure sensors are used to measure line pressure and differential pressure (paragraphs [0058] and [0059]), and that the differential pressure is measured using a venturi tube (paragraph [0046]).
Because Broden and Eastoe both disclose structures for measuring line pressure and differential pressure with a venturi tube, it would have been obvious for one having ordinary skill in the art before the effective filing date of the present application to substitute the first and second pressure sensors and venturi tube of Eastoe for the differential pressure sensor and line pressure sensor of Broden to achieve the predictable result of providing structures that measure line pressure and differential pressure.
Broden as modified by Strei and Eastoe discloses a process fluid conduit (Broden: 4 and Eastoe: 101) constructed from a material (Strei: col. 2, line 64 - col. 3, line 9) suitable for exposure to saltwater, the process fluid conduit (Eastoe: 101) having a first internal diameter proximate the first process fluid penetration (Eastoe: at 11; see Fig. 1) and a second internal diameter proximate the second process fluid penetration (Eastoe: at 12; see Fig. 1), wherein the first and second internal diameters are different (Eastoe: see Fig. 1);

Conclusion
Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
