Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claims 2-8, and 10-20 rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Claims 2,10 and 17 recites “detect a second radiofrequency signal outside the charging transmitter device” which is unclear.
Claim language “detect a second radiofrequency signal outside the charging transmitter device” and “wherein the detection circuit is further configured to detect the movement of the power receiver device based on the second radiofrequency signal detected by the antenna” the specification recites the following:
[0057] The detection circuit LPCD is configured to detect an amplitude and/or phase change in the radiofrequency signal RX1, RX2 sensed by the antenna ANT1 when the charging transmitter POL proceeds with charging of the power receiver LST.
[0058] The detection of an amplitude and/or phase change in the radiofrequency signal RX1, RX2 allows detecting a movement of the power receiver LST relative to the charging transmitter POL. When an amplitude and/or phase change is detected, then the detection circuit LPCD is configured to emit a detection signal SIGD.
[0059] Thus, the detection circuit LPCD is not only used to detect the presence of a power receiver LST at the beginning of the NFC communication but also to detect a movement of the power receiver POL relative to the charging transmitter LST.
[0060] More particularly, the detection circuit LPCD comprises a step-down converter IQ (also referred to as “In-Phase Quadrature (IQ) downconverter”) associated with low-pass filters so as to be able to convert a radiofrequency signal RX1, RX2 received from the antenna ANT1 into two continuous signals, respectively indicative of the amplitude and of the phase of the radiofrequency signal RX1, RX2. Alternatively, it is possible to provide for a detection circuit LPCD comprising an analog-to-digital converter to extract the amplitude and the phase of the radiofrequency signal RX1, RX2.
[0061] Afterwards, these continuous signals are compared with thresholds in order to detect amplitude and phase changes in the radiofrequency signal RX1, RX2 revealing the movement of a power receiver LST, notably in the electromagnetic field of the charging transmitter POL.
[0084]During charging, the method comprises a continuous control 31 of the amplitude and phase of the radiofrequency signal RX1, RX2 detected by the antenna ANT1 of the charging transmitter POL.
The specification does not state that there is a separate RF signal besides the transmitter signal that is producing the RX1 and RX2. Specifically, the specification does not state that signals RX1, RX2 are signals produced from outside the charging transmitter device or if they are the transmitters RF signal that is modulated/changed due to the movement of the power receiver device.
Examiner will interpret the “second radiofrequency signal” as an “radiofrequency signal sensed by the antenna when the charging transmitter proceeds with charging of the power receiver”.
Claim 3-8 and 11-16 and 18-20 are included in this rejection based on their dependence on claims 2,10 and 17.

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 6,8,14,16, and 20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Tramoni (US 20200382165) in view of Suzuki (US 20140191819).
