OFFICE ACTION:
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 .
Continued Examination Under 37 CFR 1.114
A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection.  Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.  Applicant's submission filed on September 9, 2024 has been entered.
Response to Amendment
The amendment filed September 9, 2024 has been entered. Claims 1-6 and 8-16 remain pending in the application, and claims 7 and 17-18 were cancelled. Applicant’s amendments to the claims have overcome each and every 103 rejection previously set forth in the Final Office Action mailed July 17, 2024.
Claim Objections
Claim 2 and 8 are objected to because of the following informalities:
in claim 2, line 3: “the” should be inserted before “temporal segments”; and
in claim 8, line 2: “a duration” should be “their respective periodic duration”.  Appropriate correction is required.
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 5-6, 9-10, and 12-15 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.
Claim 5 recites “the anesthetized patient state” in lines 1-2 in which there is insufficient antecedent basis for this limitation in the claim.  Also, claim 5, lines 1-4 recite:
wherein the anesthetized patient state is a selection of any of insufficient anesthetic level, low anesthetic level, sufficient anesthetic level, normal breathing function, capable of sustaining breathing or in need of ventilator
It is not clear what relationship this recitation has with any of the recitations (of claim 1) that have come before it.  It appears that the recitation of claim 5 is wholly separate and distinct from all the recitations (of claim 1) that have come before it.
Claim 6 recites “value/s” in lines 2, 4, 5 (two occurrences), 6, and 7, but it is not clear if this recitation means there is a single value or a plurality of values.  Clarification is required.  Also, it is not clear if “the additional amplitude values” of claim 6, lines 5-6 is intended to mean that “additional amplitude value/s” of claim 6, lines 4-5 is intended to mean a plurality of values or not.  Clarification is required.
Claim 9 recites the duration (TPeriodic) is selected using a strongest periodic noise component of the noise signal (SNoise), which renders the claim indefinite. There is a plurality of durations (one for each temporal segment).  Are each of these durations based on a strongest periodic noise component of the noise signal or just one of them? This ambiguity renders claim 9 indefinite.
Claim 10 recites “processing circuitry being configured to perform the method according to claim 1” in line 6, which renders the claim indefinite.  Claim 1 recites a method that involves physical elements that cannot be performed by processing circuitry.  In particular, claim 1 recites
“generating a single stimuli signal (SStimuli) using the anesthetizing monitoring unit, wherein the single stimuli signal (SStimuli) comprises a single pulse and is configured to stimulate a motor nerve of a patient,
outputting the generated single stimuli signal (SStimuli) to stimulating electrodes on the patient using an output port of the anesthetizing monitoring unit,
receiving a single evoked electromyography, EMG, response signal (SResponse) from receiving electrodes on the patient at an input port of the anesthetizing monitoring unit…” in lines 4-11.
The features of the generation of the stimuli signal and the use of the electrodes are aspects that the processing circuitry of claim 10 cannot perform.  As such, the metes and bounds of the claim are not clear.
Claim 12 recites “A computer program is provided comprising computer-executable instructions for causing an anesthetizing monitoring unit, when the computer-executable instructions are executed on a processing unit comprised in the anesthetizing monitoring unit, to perform the method according claim 1” in lines 1-4, which renders the claim indefinite.  Claim 1 recites a method that involves physical elements that cannot be performed by processing unit.  In particular, claim 1 recites
“generating a single stimuli signal (Sstimuli) using the anesthetizing monitoring unit, wherein the single stimuli signal (SStimuli) comprises a single pulse and is configured to stimulate a motor nerve of a patient,
outputting the generated single stimuli signal (SStimuli) to stimulating electrodes on the patient using an output port of the anesthetizing monitoring unit,
receiving a single evoked electromyography, EMG, response signal (SResponse) from receiving electrodes on the patient at an input port of the anesthetizing monitoring unit…” in lines 4-11.
The features of the generation of the stimuli signal and the use of the electrodes are aspects that the processing unit of claim 12 cannot perform.  As such, the metes and bounds of the claim are not clear.
Claims 13-14 are rejected by virtue of its dependence from claim 12.
Claim 15 is rejected by virtue of its dependence from claim 6.
Claim 15 recites “the threshold values” in lines 1-2, but it is not clear if this recitation is the same as, related to, or different from “a set of predetermined amplitude value/s thresholds” of claim 1, lines 5.  If they are the same, consistent terminology should be used.  If they are different, their relationship should be made clear.  Also, if they are different, there is insufficient antecedent basis for this limitation in the claim.
The following is a quotation of 35 U.S.C. 112(d):
(d) REFERENCE IN DEPENDENT FORMS.—Subject to subsection (e), a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers.
The following is a quotation of pre-AIA  35 U.S.C. 112, fourth paragraph:
Subject to the following paragraph [i.e., the fifth paragraph of pre-AIA  35 U.S.C. 112], a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers.
Claims 10 and 12-14 are rejected under 35 U.S.C. 112(d) or pre-AIA  35 U.S.C. 112, 4th paragraph, as being of improper dependent form for failing to further limit the subject matter of the claim upon which it depends, or for failing to include all the limitations of the claim upon which it depends.
Claim 10 recites “processing circuitry being configured to perform the method according to claim 1” in line 6.  According to one interpretation, the recitation of claim 10 is not including the physical elements of claim 1 that cannot be performed by processing circuitry.  In particular, claim 1 recites
“generating a single stimuli signal (Sstimuli) using the anesthetizing monitoring unit, wherein the single stimuli signal (SStimuli) comprises a single pulse and is configured to stimulate a motor nerve of a patient,
outputting the generated single stimuli signal (SStimuli) to stimulating electrodes on the patient using an output port of the anesthetizing monitoring unit,
receiving a single evoked electromyography, EMG, response signal (SResponse) from receiving electrodes on the patient at an input port of the anesthetizing monitoring unit…” in lines 4-11
The features of the generation of the stimuli signal and the use of the electrodes are aspects that the processing circuitry of claim 10 cannot perform.  According to one interpretation, all the features of claim 1 are not incorporated into claim 10, which is improper.
Claim 12 recites “A computer program is provided comprising computer-executable instructions for causing an anesthetizing monitoring unit, when the computer-executable instructions are executed on a processing unit comprised in the anesthetizing monitoring unit, to perform the method according claim 1” in lines 1-4, which renders the claim indefinite.  Claim 1 recites a method that involves physical elements that cannot be performed by processing unit.  In particular, claim 1 recites
“generating a single stimuli signal (Sstimuli) using the anesthetizing monitoring unit, wherein the single stimuli signal (SStimuli) comprises a single pulse and is configured to stimulate a motor nerve of a patient,
outputting the generated single stimuli signal (SStimuli) to stimulating electrodes on the patient using an output port of the anesthetizing monitoring unit,
receiving a single evoked electromyography, EMG, response signal (SResponse) from receiving electrodes on the patient at an input port of the anesthetizing monitoring unit…” in lines 4-11.
The features of the generation of the stimuli signal and the use of the electrodes are aspects that the processing unit of claim 12 cannot perform.  According to one interpretation, all the features of claim 1 are not incorporated into claim 12, which is improper.
Claims 13-14 are rejected by virtue of its dependence from claim 12.
Allowable Subject Matter
Claims 1-4, 8, 11, and 16 are allowed though claims 2 and 8 are objected to.
Claims 5-6, 9-10, and 12-15 would be allowable if rewritten to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action.
The following is an examiner’s statement of reasons for allowance: The amendments filed September 9, 2024 include amended claim limitations to independent claim 1. The amended claim limitations recite “the temporal segments each have a periodic duration (TPeriodic) matching the frequency of the electric power grid” in combination with the recitation of “the temporal segments of the noise signal (SNoise) are detected during a time interval (TNoise) not overlapping with a stimuli signal interval (TStimulus) of the single stimuli signal (Sstimuli) and not overlapping with the duration of the response signal (TResponse)”. This is not taught by the Kurtz reference (US 20170245776) or the Bray reference (US 20180256097), as relied upon in the Final Office Action dated July 17, 2024, or any other reference found during a further prior art search.
Claims 2-6 and 8-16 contain allowable subject matter at least based on their dependence on claim 1.
Conclusion

APPLICANT REBUTTAL: Remarks
The various parts of the Office Action (and other matters, if any) are discussed below under appropriate headings.
Allowable Subject Matter
