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.
Claim(s) 1, 8, 11, and 12 is/are rejected under 35 U.S.C. 103 as being unpatentable over Alshamrani et al (US20200019167) in view of Xie et al (US20120154594).
Regarding claim 1, Alshamrani teaches a method of inspecting a blade of a wind turbine (para. [0034], Specifically, targets of the inspection include, for example, an office building, a residential building, a school, a hospital, a facility, a factory, or any special purpose structure such as a bridge, a wind turbine, an electrical tower, an oil/gas rig, and the like), the method comprising:
detecting a defect in a first area on one of an interior surface or an exterior surface of a wind turbine blade (claim 1, receive inspection data collected by the drone during the visual inspection of the exterior of the building, extract a location where damage and/or an environmental anomaly is suspected from the inspection data collected by the drone);
determining a second area on the other of the interior surface or the exterior surface corresponding to the first area (claim 1, send the location where damage and/or an environmental anomaly is suspected to the robot to carry out an exterior inspection at the location where damage and/or an environmental anomaly is suspected or an interior inspection at a corresponding interior location of the building); and
displaying an image comprising the first area and the second area (para. [0050], The user interface 202 also receives results of data processing from the data processing module 206 and presents the results to a user; para. [0059], At step S318, the data collected by the robot 103 for exterior inspection or the data collected by the robot 103 for indoor inspection are received via the network 105 and sent to the data processing module 206 of the inspection operation controller 101. At step 322, a result of the data analysis process is output to a user via the user interface 202. The results are interpreted to include the location where damage exists, which would be the first and second areas), wherein:
the second area is correlated to the first area based on an exterior signal produced by an analysis of the exterior surface of the wind turbine blade and an interior signal produced by an analysis of the interior surface of the wind turbine blade (claim 1, receive inspection data collected by the drone during the visual inspection of the exterior of the building, extract a location where damage and/or an environmental anomaly is suspected from the inspection data collected by the drone, send the location where damage and/or an environmental anomaly is suspected to the robot to carry out an exterior inspection at the location where damage and/or an environmental anomaly is suspected or an interior inspection at a corresponding interior location of the building, receive inspection data collected by the robot during the exterior and/or interior inspection. It would be obvious to perform analysis to determine the damage location and generate a corresponding signal).
Alshamrani fails to teach wherein the first area and the second area are displayed side-by-side or overlaid on one another in the image.
However Xie teaches wherein a first area and a second area are displayed side-by-side or overlaid on one another in the image (para. [0044]-[0045]).
Therefore taking the combined teachings of Alshamrani and Xie as a whole, it would have been obvious to one of ordinary skill in the art at the time the invention was filed to incorporate the steps of Xie into the method of Alshamrani. The motivation to combine Xie and Alshamrani would be to allow defects in a device under inspection to be more readily identified (para. [0044] of Xie).
Regarding claim 8, Alshamrani teaches a system for inspecting a structure (para. [0034], Specifically, targets of the inspection include, for example, an office building, a residential building, a school, a hospital, a facility, a factory, or any special purpose structure such as a bridge, a wind turbine, an electrical tower, an oil/gas rig, and the like), the system comprising:
an external sensing device comprising an external sensor configured to analyze an exterior of the structure (claim 1, receive inspection data collected by the drone during the visual inspection of the exterior of the building, extract a location where damage and/or an environmental anomaly is suspected from the inspection data collected by the drone) and produce an external data signal (claim 1, send an exterior inspection objective to the drone to instruct the drone to carry out a visual inspection of the exterior of the building and/or inspect an exterior environment of the building);
an internal sensing device comprising an internal sensor configured to analyze an interior of the structure (claim 1, send the location where damage and/or an environmental anomaly is suspected to the robot to carry out an exterior inspection at the location where damage and/or an environmental anomaly is suspected or an interior inspection at a corresponding interior location of the building) and produce an internal data signal (claim 1, receive inspection data collected by the robot during the exterior and/or interior inspection); and
a display configured to display an image (para. [0050], The user interface 202 also receives results of data processing from the data processing module 206 and presents the results to a user; para. [0059], At step S318, the data collected by the robot 103 for exterior inspection or the data collected by the robot 103 for indoor inspection are received via the network 105 and sent to the data processing module 206 of the inspection operation controller 101. At step 322, a result of the data analysis process is output to a user via the user interface 202. The results are interpreted to include the location where damage exists, which would be the first and second areas), wherein
the second area being correlated to the first area based at least in part on the internal data signal (claim 1, receive inspection data collected by the drone during the visual inspection of the exterior of the building, extract a location where damage and/or an environmental anomaly is suspected from the inspection data collected by the drone, send the location where damage and/or an environmental anomaly is suspected to the robot to carry out an exterior inspection at the location where damage and/or an environmental anomaly is suspected or an interior inspection at a corresponding interior location of the building, receive inspection data collected by the robot during the exterior and/or interior inspection. It would be obvious to perform analysis to determine the damage location and generate a corresponding signal).
Alshamrani fails to teach wherein the image comprises a first area of the structure generated from the external data signal and a second area of the structure generated from the internal data signal.
However Xie teaches an image comprising a first area and a second area (para. [0044]-[0045]). It would be obvious to apply the first and second areas obtained by Alshamrani to the image of Xie.
Therefore taking the combined teachings of Alshamrani and Xie as a whole, it would have been obvious to one of ordinary skill in the art at the time the invention was filed to incorporate the steps of Xie into the method of Alshamrani.

[0070], Here the diameter of the blade root end, known to be 6.2 feet, is defined).
Therefore taking the combined teachings of Alshamrani and Xie with Newman as a whole, it would have been obvious to one of ordinary skill in the art at the time the invention was filed to incorporate the steps of Newman into the method of Alshamrani and Xie.

[0057], thereby provides a method of positioning the pig at any desired target position within the pipeline. It would be obvious to apply the steps to the interior of the wind turbine blade of Alshamrani).
