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 .
In response to the restriction requirement, Applicant elected claims 1-2 for further examination. As a result, claims 3-5 are withdrawn from further prosecution.
Claim Rejections - 35 USC § 103
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) 1-2 is/are rejected under 35 U.S.C. 103 as being unpatentable over Nakayama (US 2020/0395996) in view of Rebenshtok et al. (WO 2019/215718).
Nakayama discloses an antenna-directivity adjustment system comprising a radio communication device equipped with an antenna (FIG. 1, element 2: Antenna), an antenna-directivity adjustment device (paragraph [0003]: Means for adjusting the direction of an antenna), and a notification device (Abstract: The outdoor apparatus 4 displays received power and the calculated propagation-path information),
wherein the antenna-directivity adjustment device comprises
a measurement information acquisition module configured to acquire angle information relating to a horizontal angle, a vertical angle, and a rotation angle of the antenna as well as received-signal levels of the antenna for receiving vertical polarization and horizontal polarization (FIG. 5: The received power detections 24-25 detect the received-signal levels of the vertically polarized waves and the horizontally polarized waves (paragraph [0046])),
a first information generator configured to generate first information representing the received-signal level for each angle (FIG. 5: The received power detections 24-25 detect the received-signal levels of the vertically polarized waves for the vertical angle and the horizontally polarized waves for the horizontal angle (paragraph [0046]),
a third information generator configured to calculate a cross-polarization discrimination (FIG. 5, elements 38-39: Cross-polarization discrimination calculation), and
wherein the notification device is configured to generate notification information visually expressing the generated information (FIG. 3: The apparatus 4 displays the first information RSL, the third information XPD).
Nakayama however is silent on measuring an interference level between the vertical polarization and the horizontal polarization with the antenna to generate second information representing the interference level for each angle, and wherein the third information generator configured to calculate a cross-polarization discrimination based on the first information and the second information so as to generate third information representing the cross-polarization discrimination for each angle.
Rebenshtok et al. teaches that the polarization discrimination in a wireless communication system is measured by a cross-polarization discrimination (XPD) (the third information), which is defined as the ratio of the received power of the co-polarization wave (the first information) to the received the cross-polarization wave (paragraph [0035]), wherein the cross-polarization wave is the interference between the orthogonal polarizations such as vertical horizontal (the second information).
Therefore, it would have been obvious for one having ordinary skill in the art at the time invention was made to modify Nakayama’s communication system to also obtain the interference level between the vertical and horizontal polarizations for further calculating the cross-polarization discrimination as taught by Rebenshtok et al. (paragraph [0035]).
