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 5-6, 12-13, and 19-20 are rejected under 35 U.S.C. 103 as being unpatentable over Faragher et al (US 2019/0011569 A1) in view of He (US 2013/0321048 A1).
Regarding Claim 5, 12, and 19, Faragher discloses the environmental parameter comprises [0038 for using sensors (monitoring) receiver’s environment (barometric and geomagnetic bearings)].
Faragher fails to explicitly teach at least one of a temperature of the environment in which the receiver is operating or a rate of change of the temperature of the environment in which the receiver is operating, and the operating parameter comprises a turning on or off of a component associated with the receiver.
He has a communication system comprises a crystal oscillator configured to output a reference clock (abstract) and teaches at least one of a temperature of the environment in which the receiver is operating or a rate of change of the temperature of the environment in which the receiver is operating, and the operating parameter comprises a turning on or off of a component associated with the receiver [0161-0164 for using temperature compensating algorithms].
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 frequency oscillating techniques, as disclosed by Faragher, further including the temperature calculations as taught by He for calculating frequency errors due to temperature drift during operation of the GPS module [He, 0162].
Regarding Claim 6, 13, and 20, Faragher teaches using a machine learning model [0177, 0208]. However, Faragher fails to explicitly teach a frequency error related to the predicted frequency related parameter is determined using at least one of a machine learning model trained to determine a frequency error based on a change in at least one monitored parameter affecting the frequency of the local frequency source or a stored look up table that associates a frequency error with a change in at least one monitored parameter affecting the frequency of the local frequency source.
He has a communication system comprises a crystal oscillator configured to output a reference clock (abstract) and teaches a frequency error related to the predicted frequency related parameter is determined using at least one of a machine learning model trained to determine a frequency error based on a change in at least one monitored parameter affecting the frequency of the local frequency source or a stored look up table that associates a frequency error with a change in at least one monitored parameter affecting the frequency of the local frequency source [0140-0142 for using learning algorithm with temperature compensation and frequency].
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 frequency oscillating techniques, as disclosed by Faragher, further including the temperature calculations as taught by He for calibrating the crystal resonator's frequency deviation versus temperature characteristic [He, 0142].
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
Sastrawan et al (US 2016/0013795 A1) has a method for controlling an oscillator based on a measurement of a frequency reference.
