OFFICE ACTION:
DETAILED ACTION
Notice of Pre-AIA  or AIA  Status
1.	The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Information Disclosure Statement
2.	The information disclosure statement (IDS) submitted on 07/13/22 has been considered by the examiner.
Priority
3.	Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55.
Specification
4.	The disclosure is objected to because of the following informalities: on the first line of paragraph [0009], the word subject should be changed to either --object-- or
--objective--, and also on this line, --to provide-- should be inserted after the word is. On the first line of paragraph [0023], the word --its-- should be inserted after at. On the penultimate line of paragraph [0028], the word In should be changed to --IN--. On line 8 of paragraph [0030], it appears that +V should be changed to -- +12V--, the reason being that figure 4 of the instant drawings shows that +12 V is supplied to the second transistor T2.
Appropriate correction is required.
Drawings
5.	The drawings are objected to because figures 1-3 of the instant drawings need to be provided with prior art labels.  Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance.

Claims 1-4 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Nakahara et al, U.S. Patent No. 5,229,818.
As to claim 1, Nakahara et al discloses, in figure 4,
a device (the combination of the voltage doubler constituted by capacitors C4 and C5, diodes D2 and D3, and resistor R4, together with comparator 16) for processing a pilot control signal (the pilot control signal is just intended use because it is not an integral component of the claimed device but rather the signal that is received by the claimed device, and therefore all of the recitations regarding the pilot control signal are similarly just intended use and as such cannot be relied upon to distinguish over Nakahara et al) having at least two modes: a continuous mode in which the pilot control signal comprises a continuous signal or an alternating mode in which the pilot control signal comprises an alternating PWM signal (as noted above, all of the recitations in claim 1 regarding the pilot control signal are just intended use and as such cannot be relied upon to distinguish over Nakahara et al) and capable of generating a binary detection signal (note that the output of comparator 16 is a binary detection signal), the state of which is an indication of the mode, the device comprising a voltage doubler and a comparator (as noted above, the voltage doubler and comparator can be read on the combination of the voltage doubler constituted by capacitors C4 and C5, diodes D2 and D3, and resistor R4, together with comparator 16).

Allowable Subject Matter
8.	Claims 6 and 7 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.

Claim Re
j
ections Under 35 USC 102
Claims 1-4 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Nakahara et al, U.S. Patent No. 5,229,818. Claims 1-3 and 5 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Jinno et al, U.S. Patent Application Publication No. 2002/0008629.
Applicant respectfully traverses these rejections for the reasons set forth below.
Applicant's invention, as recited in claim 1, includes features not disclosed or suggested by the cited prior art, namely:
A device for processin
g
a pilot control signal
the device comprising:
a voltage doubler; and a comparator,
the
pilot control signal having at least two modes:
a continuous mode in
which the pilot control signal comprises
a continuous si
g
nal or an
alternatin
q
mode in which the pilot control si
g
nal comprises an alternating
PWM signal,
and
the comparator outputs a binary detection signal based on an input of the
pilot control signal to the voltage doubler,
a state of the binary detection
signal being an indication of the mode of the pilot control signal.
(Emphasis Added)
The comparator outputs a binary detection signal based on the pilot control signal that has at least two modes. A first mode of the pilot control signal is a continuous signal, and a second mode of the pilot control signal is an alternating PWM signal. The state of the binary detection signal is an indication of the mode of the pilot control signal.
Nakahara and Jinno are each relied upon as disclosing a voltage doubler and a comparator without more.
The Office gives no patentable weight to the pilot control signal as allegedly intended use. Applicant respectfully disagrees. The Pilot Control Signal goes to the essence of the invention.
"If the claim preamble, when read in the context of the entire claim, recites limitations of the claim, or, if the claim preamble is 'necessary to give life, meaning, and vitality' to the claim, then the claim preamble should be construed as if in the balance of the claim." Pitney Bowes, Inc. v. Hewlett-Packard Co., 182 F.3d 1298, 1305, 51 USPQ2d 1161, 1165-66 (Fed. Cir. 1999)." MPEP 2111.02
The preamble of claim 1 provided antecedent basis for the body of the claim which
distinguishes the claim from the cited prior art and gives 'life, meaning, and vitality" to claim 1.
See also, In re Janinski, 107 USPQ2d 2082, cited in the USPTO training materials of May 2015.
Accordingly, the pilot control signal is not merely intended use and should be accorded patentable weight in the context of claim 1.
Nakahara is directed to an image forming apparatus. In Nakahara, the output of an AC oscillation circuit 12, used for charging voltage generation to charging roller 5, is provided to the voltage doubler (asserted as C4, C5, D2, D3, and R4)/comparator 16. According to Nakahara, the output of comparator 16 is used to maintain the level of the charging AC voltage to be supplied to the drum. There is no disclosure or suggestion that the input to the voltage doubler
is anything other that the AC signal generated by oscillator 12. In other words, there is no continuous signal mode, only an oscillating (alternating) mode. Further there is no disclosure or suggestion that the input to the asserted voltage doubler is anything other than an AC signal. Finally, there is not disclosure or suggestion that the AC signal generated by oscillator 12 is a PWM signal.
Because Nakahara fails to disclose of each and every feature of claim 1, claim 1 is not subject to rejection as anticipated by Nakahara. Withdrawal of the rejection and allowance of claim 1 are respectfully requested.
Claims 2-4 depend on claim 1 and are likewise not subject to rejection as anticipated by Nakahara. Withdrawal of the rejection and allowance of claims 2-4 are respectfully requested.
Jinno is directed to a traffic signal monitor. The Office relies on Fig. 46 for applicant's
claimed voltage doubler and comparator. According to Jinno, however, the alleged comparator is a NOT circuit. Also, according to Jinno,
[0288] With the operation of the NOT circuit,
when the AC input signal IN
is input,
a rectified output signal is input to the base of the transistor Q3
41 via the zener diode D3 43 and the resistor R34 1 so that the transistor Q 341 comes on.
When the input signal IN is not applied,
the transistor Q
341 goes off so that the collector output voltage PI of the transistor Q
becomes a high level. (Emphasis Added)
In other words, there is only one mode for the input signal, that of an AC signal. The absence of the input signal is not equivalent to a continuous mode of the input signal. Further, there is not disclosure or suggestion that the AC signal input to the voltage doubler is a PWM signal.
Because Jinno fails to disclose of each and every feature of claim 1, claim 1 is not
subject to rejection as anticipated by Jinno. Withdrawal of the rejection and allowance of claim
1 are respectfully requested.
Claims 2, 3, and 5 depend on claim 1 and are likewise not subject to rejection as
anticipated by Nakahara. Withdrawal of the rejection and allowance of claims 2, 3, and 5 are respectfully requested.
Allowable claims 6 and 7 are rewritten into independent form.
In view of the amendments and remarks set forth above, applicant submits that this application is in condition for allowance which action is respectfully requested.
The Director is hereby authorized to charge any fees that may be due, and to credit any overpayment to Deposit Account No. 02-4800.
Respectfully submitted, BUCHANAN INGERSOLL & ROONEY PC

NEXT OFFICE ACTION: DETAILED ACTION
Response to Amendment
1.	Applicant's amendment filed on 01/23/25 has been received and entered in the case. Claims 6 and 7 are allowable over all of the prior art of record for the reasons indicated in the previous office action. However, because no arguments have been set forth by applicant against the previously applied prior art rejections based on Nakahara et al and Jinno et al, claims 1-5 remain rejected based on these two references, for the reasons set forth in the previous office action.
Claim Objections
2.	Claim 1 is objected to because of the following informalities:
On the first line of claim 1, a comma should be inserted after the word signal. Also in claim 1, the word --and-- should be inserted at the end of line 3, and note that the word and at the beginning of line 4 should be deleted.
