Office Action

§103 §112
DETAILED ACTION 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. Response to Arguments Applicant's arguments filed 02/18/2025 have been fully considered but they are not persuasive. With respect to the rejection under 35 U.S.C. 112(b), the Applicant purports that the term “signal probe” is not indefinite and should not be rejected under 35 U.S.C. 112(b). In support of their argument the Applicant further purports that the Examiner’s “conclusion is not supported by any evidence or any serious attempt to construe the meaning of the term, and further confuses breadth with indefiniteness,” citing the website Wikipedia for a definition of “test probe.” In response the Examiner points to the previously filled 112b rejection. As was set forth in the in the previously filled nonfinal rejection, the drawings filed 12/28/2023 make clear that the “signal probe” is a hardware component that couples the “cellular transceiver” circuitry to the “automotive radar sensor.” The existence of the claimed probe was not set forth as indefinite. Instead, the claimed use of probing an automotive radar signal sent from one or more automobiles using a signal probe was indicated as indefinite. One of ordinary skill in the art understands “a radar signal” as a radio-frequency (RF) electromagnetic wave transmitted from a radar antenna toward a target, which is then reflected back to the radar receiver. The claimed action of probing a signal suggests means for collecting the transient electromagnetic wave. Neither the specification or drawings clarify how a hardware component that couples the “cellular transceiver” circuitry to the “automotive radar sensor” may collect transient electromagnetic waves reflected back to the radar receiver from a target object. The aforementioned limitation is not simply broad, but is indefinite as it claims a contradiction that blurs the definition of the “signal probe.” The Examiner maintains the 112b rejection. With respect to the rejection under 35 U.S.C. 102 based on AGARDH and the rejection of dependent claims under 35 U.S.C 103, the Applicant states that the prior art does not disclose “an amplifier coupled to the signal probe” as recited by independent claims 19 and 33 and subject matter recited in dependent claims 20 and 26. With respect to claim(s) 19 and 33, Applicant’s arguments have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Further, Applicant’s arguments regarding claim 20 have been fully considered and are persuasive. The 35 U.S.C. 102 rejection of claim 20 has been withdrawn. With respect to the Applicants arguments regarding claim 26 and paragraph [0072] of AGARDH, the Applicant purports that “None of this has anything to do with a signal strength measurement result.” The Examiner respectfully disagrees. As corroborated in the applicants’ arguments on page 13 of their remarks, paragraph [0072] deals with triggering an uplink data transmission of a “buffer status report“ from a User Equipment(UE) to a base station. Paragraph [0072] clarifies, “a buffer status report indicating data which the terminal UE1 is desirous to transmit in the UL.” Paragraph [0041] clarifies that the “desirous” data may include the power level of the received radar signal. As AGARDH discloses initiating an uplink transmission upon gathering “desirous” data which may include “power level,” the Examiner maintains the rejection of claim 26. 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. Claim 19-36 are 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. Regarding claim 19 and similarly claim 33, it is not clear of what encompasses and is meant by the term “signal probe.” As claimed it is unclear what the “signal probe” explicitly is or how it could be configured to “probe an automotive radar signal sent from one or more automobiles.” As claimed the term is excessively broad in nature and the meets and bounds of the claimed limitation cannot be ascertained by one skilled in the art. A review of the specification sets forth the term ” signal probe.” Review of the specification reveals on Page 6 lines 21-22 “The signal probe 131 may be a high-pass filter or a duplexer with low-pass and high-pass filters,“ but the examiner can find no further clarification regarding “probe an automotive radar signal sent from one or more automobiles. “Figures 1-5 of the drawings filed 12/28/2023 reveal that the “signal probe” is a hardware component that couples the “cellular transceiver” circuitry to the “automotive radar sensor,” but additionally does not provide explicit definition of how the signal probe might be configured to “probe an automotive radar signal sent from one or more automobiles.” One of ordinary skill in the art understands “a radar signal” as a radio-frequency (RF) electromagnetic wave transmitted from a radar antenna toward a target, which is then reflected back to the radar receiver. The claimed action of probing a signal suggests means for collecting the transient electromagnetic wave. Neither the specification or drawings clarify how a hardware component that couples the “cellular transceiver” circuitry to the “automotive radar sensor” may collect transient electromagnetic waves reflected back to the radar receiver from a target object. It suggested applicant amend the claims to be consistent with the “signal probe” as disclosed by the specification and clearly disclose what the limitation “probe an automotive radar signal sent from one or more automobiles” means as it is not clear how the Applicant intends to limit the term based on review of the specification. For examination purposes the term “signal probe” as recited by claims 19 and 33 will be interpreted as a hardware component that couples the “cellular transceiver” circuitry to the “automotive radar sensor.” Claims 20-32 and 34-36 are also rejected based on their dependency of the defected parent claim(s). 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.
