Office Action

§102 §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 . Response to Arguments Applicant's arguments filed October 17th, 2025 have been fully considered but they are not persuasive. Applicant argues that the prior art does not teach the claims because Au discloses a second tilt sensor for a different antenna. However, the previous rejection did not rely upon this. As stated in the previous office action, Au, column 5, lines 14-15 states that each numbered mechanism can be made up of multiple sensors, and further, col. 5 lines 24-26 defines the different types of sensor mechanisms that can be used, therefore teaching the limitations of the claims. 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 (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 the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claims 1-5, 10-15, and 20 are rejected under 35 U.S.C. 102(a)(1)(a)(2) as being anticipated by Au (US 9502764 B2), herein referred to as Au. Regarding claim 1, Au discloses an antenna monitoring device configured to monitor an alignment of an antenna (column 2, lines 4-11, 22-26), the antenna monitoring device comprising: a first sensor (306) configured to measure an antenna (302) alignment parameter of the antenna using a first type of measurement mechanism (col. 5, lines 24-26); a second sensor (col. 5 lines 14-15, plurality of sensors) configured to measure the same antenna (302) alignment parameter of the same antenna using a second type of measurement mechanism (col. 5, lines 24-26); and a processor (310) configured to determine the antenna alignment parameter based on the measurements from the first and second sensors (col. 6, lines 37-50).

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. 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 6-9 and 16-19 are rejected under 35 U.S.C. 103 as being unpatentable over Au and further in view of Switzer et al. (US 9708903 B2), herein referred to as Switzer. Regarding claim 6, Au anticipates all limitations of base claim 1. Au does not disclose the processor being configured to determine the antenna alignment parameter by: using the antenna alignment parameter measured by the second sensor responsive to determining that the first sensor has exceeded its measurement range limitation. However, Switzer discloses a system in which a process is configured to determine a parameter by: using the alignment parameter measured by the second sensor (130) responsive to determining that the first sensor (105) has exceeded its measurement range limitation (col. 14, lines 27-42). While the system of Switzer is not an antenna, the actions of the processor in regard to checking sensor parameters does not rely on the underlying system of which the sensor is tracking. Therefore, it would have been obvious to one of ordinary skill in the art prior to the effective filing date to combine the teachings of the references and make the device of Au, the processor being configured to determine the antenna alignment parameter by: using the antenna alignment parameter measured by the second sensor responsive to determining that the first sensor has exceeded its measurement range limitation, as suggested by the teachings of Switzer, to ensure the sensor information is with the predetermined range (col. 14, lines 27-31). Regarding claim 7, Au anticipates all limitations of base claim 1. Au does not disclose the processor being configured to determine the antenna alignment parameter by: using the antenna alignment parameter measured by the second sensor to validate the antenna alignment parameter measured by the first sensor responsive to determining that the first sensor has exceeded its measurement range limitation. However, Switzer discloses a system in which the processor is configured to determine the alignment parameter by: using the alignment parameter measured by the second sensor (130) to validate the alignment parameter measured by the first sensor (105) responsive to determining that the first sensor has exceeded its measurement range limitation (col. 14, lines 27-42). While the system of Switzer is not an antenna, the actions of the processor in regard to checking sensor parameters does not rely on the underlying system of which the sensor is tracking. Therefore, it would have been obvious to one of ordinary skill in the art prior to the effective filing date to combine the teachings of the references and make the device of Au, the processor being configured to determine the antenna alignment parameter by: using the antenna alignment parameter measured by the second sensor to validate the antenna alignment parameter measured by the first sensor responsive to determining that the first sensor has exceeded its measurement range limitation, as suggested by the teachings of Switzer, to ensure the sensor information is with the predetermined range (col. 14, lines 27-31). Regarding claim 8, Au anticipates all limitations of base claim 1. Au does not disclose the processor being configured to determine the antenna alignment parameter by: using the antenna alignment parameter measured by the second sensor to error correct the antenna alignment parameter measured by the first sensor. However, Switzer discloses a system in which the processor is configured to determine the alignment parameter by: using the alignment parameter measured by the second sensor (130) to error correct the alignment parameter measured by the first sensor (105)(col. 14, lines 43-67). While the system of Switzer is not an antenna, the actions of the processor in regard to checking sensor parameters does not rely on the underlying system of which the sensor is tracking. Therefore, it would have been obvious to one of ordinary skill in the art prior to the effective filing date to combine the teachings of the references and make the device of Au, the processor being configured to determine the antenna alignment parameter by: using the antenna alignment parameter measured by the second sensor to error correct the antenna alignment parameter measured by the first sensor, as suggested by the teachings of Switzer, to ensure the sensor information is with the predetermined range (col. 14, lines 27-31). Regarding claim 9, Au anticipates all limitations of base claim 1. Au does not disclose the processor being configured to determine the antenna alignment parameter by: discarding the antenna alignment parameter measured by the first sensor; and using the antenna alignment parameter measured by the second sensor. However, Switzer discloses a system in which the processor is configured to determine the alignment parameter by: discarding the alignment parameter measured by the first sensor (105); and using the alignment parameter measured by the second sensor (130)(col. 14, lines 47-51). While the system of Switzer is not an antenna, the actions of the processor in regard to checking sensor parameters does not rely on the underlying system of which the sensor is tracking. Therefore, it would have been obvious to one of ordinary skill in the art prior to the effective filing date to combine the teachings of the references and make the device of Au, the processor being configured to determine the antenna alignment parameter by: discarding the antenna alignment parameter measured by the first sensor; and using the antenna alignment parameter measured by the second sensor, as suggested by the teachings of Switzer, to ensure the sensor information is with the predetermined range (col. 14, lines 27-31).
