DETAILED ACTION
Status of Claims
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claims 1-20 are pending.
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.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claims 1-20 are rejected under 35 U.S.C. 103 as being unpatentable over Uchikubo et al. (US 6480762 B1, 2002-11-12) (hereinafter “Uchikubo”) in view of Litichever et al. (US 20190385057 A1, 2019-12-19) (hereinafter “Litichever”).
Regarding claims 1-20, Uchikubo teaches a method of detecting whether an external wire is connected to an input terminal on an external medical system, the method comprising: monitoring a signal associated with the input terminal, the input terminal located on an exterior panel of the external medical system and configured for receiving an external wire. See, e.g., 16:45-21:55; Figs. 17-26 and associated text.
Uchikubo does not expressly teach using spectral techniques.
Litichever teaches frequency-domain and time-domain techniques applicable to determining network configurations (e.g., devices interconnected by cables). See, e.g., [0270], [0274], [0288], [0291], [0398]-[0400], [0427]. See also, e.g., [0363], [0369].
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to incorporate the teachings of Litichever with the invention taught by Uchikubo such that the invention further comprises analyzing spectral content of the monitored signal; and detecting whether the external wire is connected to the input terminal based on the spectral content of the monitored signal (as recited in claim 1); wherein the signal associated with the input terminal is a time-domain signal, and the method further comprises: converting the time-domain signal to a frequency-domain signal using a fast Fourier transform (FFT) (e.g., Litichever at [0270], [0274], [0288], [0291], [0398]-[0400], [0427]) (as recited in claim 2); wherein detecting whether the external wire is connected to the input terminal is based on spectral content derived from the FFT (e.g., Litichever at [0270], [0274], [0288], [0291], [0398]-[0400], [0427]) (as recited in claim 3); wherein the external wire is determined to be connected if a measured amplitude of the frequency-domain signal is above a predetermined amplitude threshold (e.g., Litichever at [0270], [0274], [0288], [0291], [0398]-[0400], [0427]) (as recited in claim 4); wherein the external wire is determined to not be connected if a measured amplitude of the frequency-domain signal is less than a predetermined amplitude threshold (e.g., Litichever at [0270], [0274], [0288], [0291], [0398]-[0400], [0427]) (as recited in claim 5); wherein the external wire is housed within a cable containing additional wires (e.g., Litichever at [0009], [0217]-[0220]) (as recited in claim 6); wherein the external wire is connected to a device configured to receive electrical power from the external medical system (e.g., Litichever at [0009], [0217]-[0220]) (as recited in claim 7); wherein the external wire is included as part of a catheter (e.g., Uchikubo at Fig. 28) (as recited in claim 8); a method of operating an electrical system configured to provide power to one or more external components, the method comprising: monitoring a signal associated with an input terminal on an amplifier system of the electrical system, wherein the input terminal is configured for connection to an external wire (e.g., Uchikubo at 16:45-21:55; Figs. 17-26 and associated text); analyzing spectral content of the monitored signal; determining whether the external wire is connected to the input terminal based on the spectral content of the monitored signal (e.g., Litichever at [0270], [0274], [0288], [0291], [0398]-[0400], [0427]); and performing at least one of: generating a notification relaying whether the external wire is connected; and implementing safety protocols, if the external wire is connected (e.g., Uchikubo at 18:56-61, 19-50-56; Fig. 33-36 and associated text) (as recited in claim 9); further comprising: prior to analyzing spectral content, converting the monitored signal to a digital signal and processing the digital signal through FFT (e.g., Litichever at [0270], [0274], [0288], [0291], [0398]-[0400], [0427]) (as recited in claim 10); wherein the external wire is determined to be connected if a measured amplitude is above a predetermined amplitude threshold (e.g., Litichever at [0270], [0274], [0288], [0291], [0398]-[0400], [0427]) (as recited in claim 11); wherein the external wire is determined to not be connected if a measured amplitude is less than a predetermined amplitude threshold (e.g., Litichever at [0270], [0274], [0288], [0291], [0398]-[0400], [0427]) (as recited in claim 12); wherein implementing safety protocols comprises prohibiting electrical power from being delivered from a signal generator of the electrical system (e.g., Uchikubo at 18:56-61, 19-50-56; Fig. 33-36 and associated text) (as recited in claim 13); wherein generating a notification that the external wire is connected comprises providing at least one of a visual output and an audio output (e.g., Uchikubo at 18:56-61, 19-50-56; Fig. 33-36 and associated text) (as recited in claim 14); a system configured to provide electrical power to one or more external components, the system comprising: one or more input terminals formed on an exterior panel of the system, the one or more input terminals configured to receive an external wire (e.g., Uchikubo at 16:45-21:55; Figs. 17-26 and associated text); a data collection system configured to monitor and collect analog signals associated with the one or more input terminals, wherein the analog signals undergo digital signal processing in the data collection system to provide spectral content for the one or more input terminals; and a cable detection module configured to detect whether the external wire is connected to the one or more input terminals based on the spectral content (e.g., Litichever at [0270], [0274], [0288], [0291], [0398]-[0400], [0427]) (as recited in claim 15); further comprising a safety module configured to allow or prohibit power delivery to the one or more external components, based on whether the cable detection module detects the external wire (e.g., Uchikubo at 18:56-61, 19-50-56;
