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.
Claims 1-13 are rejected under 35 U.S.C. 103 as being unpatentable over McClure (US 20160154108 A1) in view of Kroeger et al (US 2019/0391276 A1).

Regarding Claim 9, McClure discloses in a case where a distance between the moving object and the one base station is less than a predetermined distance, the second positioning of the moving object based on the correction information corresponding to the one base station becomes possible [0043-0044],
and, in a case where the distance between the moving object and the one base station is equal to or more than the predetermined distance, the second positioning of the moving object based on the correction information corresponding to the one base station becomes impossible [0033, 0038-0039 for lost signals].

McClure fails to explicitly teach and the first correction information including latitude and longitude indicating the position of the first base station and time information is used regardless of an actual location of the moving object.
Kroeger has a method comprises receiving an approximate location of a rover platform based on satellite signals for a Global Navigation Satellite System (abstract) and teaches and the first correction information including latitude and longitude indicating the position of the first base station and time information is used regardless of an actual location of the moving object [0052, and 0075 for using differential corrections with longitude and latitude].
It would have been obvious to a person of ordinary skill in the art before the effective filling date of the applicant’s invention for modifying the work vehicle position techniques, as disclosed by McClure, further including the correction calculations as taught by Kroeger for the purpose to produce differential corrections for that location (Kroeger, 0075).

transmitting positioning information corresponding to the calculated position of the moving object to a base station server that selects one base station from among a plurality of base stations on the basis of the calculated position of the moving object [0015 for master and secondary base stations for moving object (rover)];
acquiring, from the base station server, correction information generated based on a satellite signal received by the one base station from the satellite [0015-0016];
and performing second positioning for calculating the position of the moving object on the basis of the correction information, wherein when the second positioning of the moving object based on first correction information corresponding to a first base station that is the one base station becomes possible [0015-0017 for using new correction signals from secondary base station],
the same positioning information as the positioning information obtained immediately before the second positioning of the moving object based on the first correction information becomes possible is transmitted to the base station server [0016-0018].
McClure fails to explicitly teach and the first correction information including latitude and longitude indicating the position of the first base station and time information is used regardless of an actual location of the moving object.
Kroeger has a method comprises receiving an approximate location of a rover platform based on satellite signals for a Global Navigation Satellite System (abstract) and teaches and the first correction information including latitude and longitude indicating the position of the first base station and time information is used regardless of an actual location of the moving object [0052, and 0075 for using differential corrections with longitude and latitude].
It would have been obvious to a person of ordinary skill in the art before the effective filling date of the applicant’s invention for modifying the work vehicle position techniques, as disclosed by McClure, further including the correction calculations as taught by Kroeger for the purpose to produce differential corrections for that location (Kroeger, 0075).
Response to Arguments
Applicant's arguments fail to comply with 37 CFR 1.111(b) because they amount to a
general allegation that the claims define a patentable invention without specifically pointing out how the language of the claims patentably distinguishes them from the references.
On page 3, first paragraph of applicant’s arguments, applicant states that the art does does not each base station correction using latitude/longitude. The examiner respectfully disagrees: McClure teaches a hysteresis effect to maintain the rover in contact with the base station (receiving position correction data from base station [McClure, 0041]. Kroeger strengthens the correction by using differential corrections values form the DGPSR stations and the locations of reference station that are conveyed to the rover with DCM, therefore the rover receives correction information for fixed virtual reference station locations and can interpolate the data [Kroeger, 0049].
On page 3, third paragraph of applicant’s arguments, applicant states that the Kroeger does not each base station correction using latitude/longitude. The examiner respectfully disagrees: Kroeger solves the well-know problem of differential correction instability by maintaining fixed reference station positions independent of rover movement [Kroeger, 0036-0037] which directly applies the same principles of receiving corrections for a fixed first position rather than continuously updating based on rover location to any GNSS correction system including a physical base station network like the applicant’s.
On page 3, last paragraph of applicant’s arguments, applicant states argues that the combination of McClure and Kroeger is not obvious. The examiner respectfully disagrees: both references address the identical problem of instability caused by frequent position-based updates in GNSS correction systems. Kroeger teaches that maintaining fixed reference station position improves accuracy and eliminates constant updates [Kroeger, 0003, 0037] enhance McClure’s hysteresis-based system for keeping corrections tied to the current base station [McClure, 0041].
