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 . A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 4/6/26 has been entered. 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. Claims 1-12, 17-19, 30-37 are rejected under 35 U.S.C. 103 as being unpatentable over the Applicant provided prior art US Patent 9,347,904 to Schaefer in view US Patent 5,836,087 to Wilson.

Doing so, would result in the sensor segment of Schaefer being connected to each other following the method taught by Wilson. The support rod of Schaefer being threaded to each other with the male/female connector are the data connectors. Both inventions of Schaefer and Wilson having an interconnectable rod assembly with a rod section, a circuit housing, and telescoping section, Wilson teaches a method which allows an easier maintenance. Once the invention of Wilson is integrated with the invention of Schaefer, the heigh the multiple segment would be adjustable since each section is connected via thread. Therefore, they are disconnectable. In Reference to Claim 32 Schaefer discloses the sensor cable segments each include: a housing (Fig. 17, 272); the housing having an elongated shape extending from an upper end to a lower end; a sensor circuit (Fig. 8, 84); the sensor circuit positioned in the housing; the sensor circuit having one or more sensors (Fig. 8, 87, 86); a support cable (Fig. 17, 210); the support cable extending from an upper end to a lower end; the lower end of the support cable configured to operably connect to the upper end of the housing (As showed in Fig. 210); the upper end of the support cable configured to operably connect to the lower end of the housing of a higher one of the plurality of sensor cable segments in the multi-segment sensor cable; a data cable (Fig. 89, 75) extending from an upper end to a lower end; the upper end of the data cable having an electrical connector configured to communicatively connect to the lower electrical connector of the sensor circuit of the higher one or the plurality of sensor cable segments; wherein during operation, the sensor circuit is configured to communicate a first set of data gathered from the one or more sensors of the sensor circuit via the data cable (Since Schaefer discloses the senor and data cable, the collecting of data is a function of the recited structure); wherein when a lower one of the plurality multiple sensor cable segments in the multi-segment sensor cable is communicatively connected to the lower electrical connector of the sensor circuit, wherein the sensor circuit is configured to receive a second set of data from the lower sensor cable segment and communicate the second set of data via the data cable. (As showed in Fig. 16, there are multiple sensor sections, obviously, each set of sensor will collect info at different locations) Schaefer does not teach connectors. Wilson teaches the sensor circuit having an upper electrical connector and a lower electrical connector (As showed in Fig. 2, the female connectors at threaded end 34 and 32); the lower end of the data cable having an electrical connector (Fig. 2, the female connector at the threaded end 34 and 32) configured to communicatively connect to the upper electrical connector of the sensor circuit; It would have been obvious to one with ordinary skill in the art before the effective filing date of the claimed invention to incorporate teachings from Wilson into the invention of Schaefer. Doing so, would result in the sensor segment of Schaefer being connected to each other following the method taught by Wilson. The support rod of Schaefer being threaded to each other with the male/female connector are the data connectors. Both inventions of Schaefer and Wilson having an interconnectable rod assembly with a rod section, a circuit housing, and telescoping section, Wilson teaches a method which allows an easier maintenance. In Reference to Claims 33 and 34 Schaefer discloses a modular sensor cable system for a grain bin, comprising: a plurality of discrete sensor cable segments (Fig. 16, 204); wherein the plurality of discrete sensor cable segments each include: a housing (Fig. 17, 272); a sensor circuit (Fig. 8,84); wherein the sensor circuit has one or more sensors (Fig. 8, 84/87); wherein the sensor circuit is positioned in the housing; and a data cable (Fig. 17, 212); a support cable (Fig. 17, 210); wherein the plurality of sensor cable segments are configured to operably connect together in series to form a multi-segment sensor cable (As showed in Fig. 16) Schaefer does not teach discrete segments. Wilson teaches wherein the housings of the plurality of discrete sensor cable segments (Fig. 2, as showed, the sensor segment 14) are operably connected to the support cable (as showed in Fig. 2, the support connector 34 and 32 are integrated with the cable connector); wherein the data cables of the plurality of discrete sensor cable segments (As showed in Fig. 2, the sensor cable are discrete and linked via connectors) have electrical connectors positioned at respective ends of the data cables and configured to connect with electrical connectors of the sensor circuits to thereby communicatively connect the sensor circuits of the plurality of discrete sensor cable segments together in series;; wherein the multi-segment sensor cable extends from an upper end to a lower end. the support cable is formed of a plurality of discrete support cable segments (As showed in Fig. 2, the support cable can be connected with thread connectors) connected together in series. It would have been obvious to one with ordinary skill in the art before the effective filing date of the claimed invention to incorporate teachings from Wilson into the invention of Schaefer. Doing so, would result in the sensor segment of Schaefer being connected to each other following the method taught by Wilson. The support rod of Schaefer being threaded to each other with the male/female connector are the data connectors. Both inventions of Schaefer and Wilson having an interconnectable rod assembly with a rod section, a circuit housing, and telescoping section, Wilson teaches a method which allows an easier maintenance. In Reference to Claim 35 Schaefer discloses the support cable is single continuous cable. (Fig. 7, 82) In Reference to Claim 36 Schaefer discloses a modular sensor cable system for a grain bin, comprising: a support cable (Fig. 17, 210); a plurality sensor cable segment (Fig. 17, 212) wherein the plurality of discreate sensor cable segments are operably connected to the support cable (As showed in Fig. 17); wherein the plurality of discreate sensor cable segments each include a sensor circuit (Fig. 8, 84); wherein the sensor circuit has one or more sensors (Fig. 8, 87, 86); wherein the plurality of discreate sensor cable segments each include a data cable (Fig. 8, 75) Schaefer does not teach discreated sensor cable segment. Wilson teaches a plurality of discreate sensor cable segments (Wilson teaches the support section with sensor segment (Fig. 2, 14) is a discrete section with connectors at both sides); the data cable extending a length between a first end and a second end (Fig. 2, female connectors are both ends for date cable connector 62 and 64); the data cable having a first electrical connector (Fig. 2, respective female connector for 62) at the first end and a second electrical connector (Fig. Fig. 2, the respective female connector for 64) at the second end; wherein the second electrical connector of the data cable is configured to communicatively connect to the sensor circuit of the sensor cable segment; wherein the first electrical connector of the data cable is configured to communicatively connect to the sensor circuit of another one of the plurality of discreate sensor cable segments; wherein the first electrical connector and second electrical connector are configured to be disconnected (As showed in Fig. 2, the connector can be disconnected from each end) from sensor circuits to which they are connected. the support cable is formed of a plurality of discrete cable segments (As showed in Fig. 2, the support cable has thread connector at both ends (Fig. 2, 34 and 32)). It would have been obvious to one with ordinary skill in the art before the effective filing date of the claimed invention to incorporate teachings from Wilson into the invention of Schaefer. Doing so, would result in the sensor segment of Schaefer being connected to each other following the method taught by Wilson. The support rod of Schaefer being threaded to each other with the male/female connector are the data connectors. Both inventions of Schaefer and Wilson having an interconnectable rod assembly with a rod section, a circuit housing, and telescoping section, Wilson teaches a method which allows an easier maintenance. Claim 13 is rejected under 35 U.S.C. 103 as being unpatentable over the combination of Schaefer and Wilson as applied to claim 1 above, and further in view of US Patent 4,4,247,989 to Steffen. In Reference to Claim 13 Schaefer discloses sensors comprising the temperature sensor and the humidity sensor. Schaefer does not teach an optical sensor. Steffen teaches an optical sensor (Fig. 1, 32) It would have been obvious to one with ordinary skill in the art at the time of the invention, to incorporate teachings from Steffen into the combination of Schaefer and Wilson as applied to Claim 13. Doing so, would result in an optical sensor being integrated into the system of Schaefer. Both inventions of Schaefer and Steffen are in the same field of endeavor, Steffen teaches a method of detecting instability in grains, for detecting levels of preservation and/or deterioration of grain. So the monitoring of the storage has been improved. Claim 14 is rejected under 35 U.S.C. 103 as being unpatentable over the combination of Schaefer and Wilson as applied to claim 1 above, and further in view of US Patent Publication 2016/0178448 to Melia. In Reference to Claim 14 Schaefer discloses the monitoring system have temperature and moisture sensors. Schaefer does not teach other types of sensors. Mella teaches the monitoring system can have various combinations of different sensors and measuring principles can be used. It would have been obvious to one with ordinary skill in the art at the time of the invention, to incorporate teachings from Mella into the combination of Schaefer and Wilson as applied to Claim 14. Doing so, would result in different kinds of sensor combination being used in the system of Schaefer. Both inventions of Schaefer and Mella are in the same field of endeavor, Mella provides a method of monitoring the grain storage condition with predictable result of success. Claim 15 is rejected under 35 U.S.C. 103 as being unpatentable over the combination of Schaefer and Wilson as applied to Claim 1 in view of US Patent 4,102,194 to Eng. In Reference to Claim 15 Schaefer discloses the plurality cable segment. Schaefer does not teach the hanger bracket assembly. Eng teaches a hanger bracket assembly (Fig. 1, 16, since the plurality of cable segments 22-28 are connected to the element 16, the Office considered that the element 16 is the bracket. BIR is given to the "bracket". The Office considers that "bracket" by its function. If the Applicant considers that the bracket has special structure, it must be recited) configured to operably connect a top-most sensor cable segment of the plurality of sensor cable segments in the multi-segment sensor cable to an elevated structure of the grain bin; wherein the hanger bracket assembly is configured to connect with and suspend the top-most sensor cable segment at a plurality of different heights. (As showed in Fig. 2) Claim 16 is rejected under 35 U.S.C. 103 as being unpatentable over the combination of Schaefer and Wilson as applied to Claim 1 in view of US Patent Publication 2018/0372406 to Leafloor. In Reference to Claims 16 Schaefer discloses the upper end and the lower end of the each housing. Schaefer does not teach the tie down. Leafloor teaches a tie down configured to operably connect to the lower end of the housing of a bottom-most sensor cable segment of the plurality of sensor cable segments in the multi-segment sensor cable; wherein the tie down is configured to connect the lower end of the multi-segment sensor cable to an elevated structure of the grain bin with a floor of the grain bin using a line. (As showed in Fig. 7) It would have been obvious to one with ordinary skill in the art at the time of the invention, to incorporate teachings from Leafloor into the combination of Schaefer and Wilson as applied to Claim 1. Doing so, would result in the tie down structure of Leafloor being integrated into the design of Schaefer. Both inventions of Schaefer and Leafloor are in the same field of end, Leafloor teaches a method of securing the segment cable with a predictable result of success. Allowable Subject Matter Claims 20-29 are allowed. Response to Arguments Applicant's arguments filed 4/6/26 have been fully considered but they are not persuasive. Starting on Page 14, the Applicant argues the 102 and 103 claim rejections. The argument is true. However, the argument is based on the amended claims.
