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 .
Response to Amendment
Applicant’s amendments, filed 7 March 2025, is acknowledged. Claims 1, 3-8 and 10 are amended. Claim 2 is cancelled.
Claims 1 and 3-10 are pending in the instant application.
Response to Arguments
Applicant’s arguments, filed 7 March 2025, with respect to the objections to the specification and drawings have been fully considered and are persuasive in light of the amendments.  The objections to the specification and drawings have been withdrawn. Examiner appreciates the clarification regarding the terms “simulate” versus “stimulate”.
Applicant’s arguments with respect to the objections to the claims 4, 5 and 10  and the 112 rejections of claims 1-10 have been fully considered and are persuasive in light of the amendments.  The objections and 112 rejections to the claims have been withdrawn.
Applicant's arguments regarding the 103 rejections of claims 1 and 10 have been fully considered but they are not persuasive in light of the amendments. Examiner was not able to apply prior to claims 2-9 in the first action due to the lack of clarity as recorded in the 112(b) rejections of the previous action. Applicant did not argue that the 103 rejections of claims 1 and 10 were improper or not obvious, but that the inclusion of the amended claim 2 limitations into claim 1 moved it beyond obviousness. With the 112(b) rejections clarified, examiner was able to apply art to the amended claim 1. While art was found obvious over amended claim 1 and 10, claims 3-9 were found non-obvious over prior art and would be allowable if amended into the independent claim.
Claim Objections
Claims 1, 3 and 4 objected to because of the following informalities:
Claim 1, lines 11-12, state “electrically; a storage” but should read –electrically; and a storage--.
Claim 3, lines 9-10, state “sleeve; a drive” but should read –sleeve; and a drive--.
Claim 4, lines 11-12, state “box; a set” but should read –box; and a set--.
Appropriate correction is required.
Claim Rejections - 35 USC § 103
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.
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.
Claim 1 is rejected under 35 U.S.C. 103 as being unpatentable over Ives (US4806881A) in view of Sanus (“CFR2115, CFR2127, CFR2136, CFR2144 Instruction Manual”, 2014) and Al-Samman (“Comparative Study of Indoor Propagation Model Below and Above 6 GHz for 5G Wireless Networks”, 2019) and further in view of Rockler.com (“Accuride 2109 75-lb. Drawer Slides”, 2022) and Jin (CN209374057U)
Regarding claim 1, under broadest reasonable interpretation, examiner is interpreting claim 1 as a common signal generator stored in a common electronics rack. Ives discloses a multifunctional electric wave generator for simulation of brain wave (Abstract, “for simulation of brain wave” is intended use, so any multifunctional electric wave generator would suffice.) comprising an electric wave generator body (Figure 1), comprising a signal receiver (Col 2, lines 9-14), a frequency controller (Col 3, lines 64-65), a power amplifier (Col 5, lines 15-16), a waveform converter (Col 2, lines 16-18), an output device (Figure 1, “Output channel”), and a digital signal processor (Figure 2, “70”); the signal receiver, frequency controller, power amplifier, waveform converter, output device, and the digital signal processor are interconnected electrically (Figures 1 and 2).
Ives does not disclose the common electronics rack. Sanus discloses a base (See annotated figure below); a protective box fixedly mounted on the top of the base (See annotated figure below); a support plate located inside the protective box (See annotated figure below); and a storage mechanism disposed on the protective box for storing the electric wave generator body (See annotated figure below. The door is considered the storage mechanism. “for storing the electric wave generator body” is considered intended use and as the rack can store an wave generator it meets the limitation).

Greyscale
Neither Ives nor Sanus teach the electric wave generator body consisting of a housing, wherein the signal receiver, frequency controller, power amplifier, waveform converter, output device, and the digital signal processor are all assembled inside the housing and the housing is placed on the support plate. Al-Samman teaches in figure 1 that the function generator has a housing with the function generator electronics in the housing and the housing is placed on the support plate of an electronics storage racks as part of a standard measurement equipment setup. It would have been obvious before the effective filing date of the claimed invention to one having ordinary skill in the art to modify the multifunctional electric wave generator as taught by Ives, with putting the multifunctional electric wave generator in a housing, with the housing stored in the common electronics rack on a support shelf disclosed by Sanus as taught by Al-Samman, since such a modification would allow the electronics to be stored in a damage safe space in manner that allows the electronics to be easier moved (wheels).
Neither Ives, Sanus nor Al-Samman disclose a limit plate is fixedly mounted on at least one side of the electric wave generator body, an L-shaped plate is fixedly mounted on a top of the support plate, the L-shaped plate is slidingly connected to the limit plate. Rockler.com discloses a mounting bracket (See annotated figure below), wherein the “L” shaped bracket would be mounted to the support plate and the limit plate is mounted to the generator body (See annotated figure below). It would have been obvious before the effective filing date of the claimed invention to one having ordinary skill in the art to modify the multifunctional electric wave generator as taught by Ives, Sanus and Al-Samman, with a limit plate that is fixedly mounted on at least one side of the electric wave generator body, an L-shaped plate is fixedly mounted on a top of the support plate, the L-shaped plate is slidingly connected to the limit plate as taught by Rockler.com, since such a modification would allow the generator body to be easily slid out of the electronics rack for maintenance. Sliding shelves for electronics racks so this would be an obvious alternative.
Neither Ives, Sanus, Al-Samman nor Rockler.com disclose a screwing rod is threadedly mounted on a top of the limit plate, and the screwing rod is threadedly connected to the L-shaped plate. Jin discloses an electronics rack (Abstract) wherein the sliding drawers are mounted with screw thread rods through the limit and drawer slider (Figures 1-3). It would have been obvious before the effective filing date of the claimed invention to one having ordinary skill in the art to modify the multifunctional electric wave generator as taught by Ives, Sanus, Al-Samman and Rockler.com, with a screwing rod is threadedly mounted on a top of the limit plate, and the screwing rod is threadedly connected to the L-shaped plate as taught by Rockler.com, since such a modification would allow prevent the generator body from sliding out of the rack unexpectedly or in the case of moving the hardware rack.
Claim 10 is rejected under 35 U.S.C. 103 as being unpatentable over Ives (US4806881A), Sanus (“CFR2115, CFR2127, CFR2136, CFR2144 Instruction Manual”, 2014), Al-Samman (“Comparative Study of Indoor Propagation Model Below and Above 6 GHz for 5G Wireless Networks”, 2019), Rockler.com (“Accuride 2109 75-lb. Drawer Slides”, 2022) and Jin (CN209374057U) as applied to claim 1, in view of Leger (“How to Use a Function Generator”, 2013).
Regarding claim 10, the multifunctional electric wave generator of claim 1 was previously disclosed by Ives, Sanus, Al-Samman, Rockler.com and Jin. Ives, Sanus and Al-Samman do not explicitly disclose a control method. Leger discloses a control method (“How to Use a Function Generator” Title) of a multifunctional electric wave generator (“Function Generator) for simulation of brain wave (“for simulation of brain wave” is intended use, so any multifunctional electric wave generator would suffice) according to claim 1, comprising the following steps: Step one: Ensuring a power supply is stable (“Power on the generator” in order to power it on, a user would have to make sure it’s plugged in, thereby ensuring the power supply is stable), connecting power and ground lines correctly (“This entails connecting the ground and signal leads to your oscilloscope to check the controls.”), activating the electric wave generator and allowing it to warm up to improve frequency stability (“You use a function generator by powering it on”); Step two: Selecting or setting a modulation mode as needed (“Then you adjust the function generator until you get the appropriate signal”), wherein the modulation modes are selected from the group of amplitude modulation (“amplitude control”), frequency modulation (“frequency control”), choosing appropriate filters to filter out clutter or noise from an output signal, then or adjusting parameters, wherein the parameters are selected from the group of waveform type (“pick the shape of the output”, frequency, amplitude (“amplitude control”), through a microprocessor to ensure stable DC power supply to an internal circuit of the electric wave generator body (“Its direct current (DC) offset control changes the signal’s average voltage with regard to the ground”); Step three: Selecting a desired waveform type through a waveform converter (“pick the shape of the output”, wherein the waveform type is selected from the group of sine wave, square wave, and triangle wave (Paragraph 3 and 4), setting a desired range of signal output frequency range by a frequency controller (Paragraph 6), adjusting a fine-tuning knob or a keyboard to input a precise frequency (Paragraph 6), adjusting an output power of the power amplifier as needed to ensure sufficient signal strength (Paragraph 5), and monitoring waveform, frequency, amplitude, and other parameters of the output signal in real-time through a display device (“Then you adjust the function generator until you get the appropriate signal and attach the function generator’s ground and signal leads to the device under test’s input and ground terminals.” A user would have to monitor the parameters in order to adjust the generator), utilizing a digital signal processor to further process and optimize the output signal (“Then you adjust the function generator until you get the appropriate signal and attach the function generator’s ground and signal leads to the device under test’s input and ground terminals.” As disclosed by Ives, the function generator contains a digital signal processor, so adjusting the parameters would be utilizing the processor and a user would not adjust a signal to be less optimal.) As Leger is describing commonly known steps for using a wave generator it would have been obvious before the effective filing date of the claimed invention to one having ordinary skill in the art to modify the multifunctional electric wave generator as taught by Ives, Sanus, Al-Samman, Rockler.com and Jin with steps of using a wave generator as taught by Leger, since such a modification would be using the wave generator in manner that is commonly known in the art and within the normal functions of the wave generator.
Allowable Subject Matter
Claims 3-9 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.
The following is a statement of reasons for the indication of allowable subject matter:  The art cited in the current office action is the closest prior art. The instant application of claim 1 teaches a multifunctional electric wave generator with a base, a protective box mounted on the base, a support plate inside the protective box, a storage mechanism disposed on the protective box, a limit plate mounted to the multifunctional electric wave generator wherein the limit plate is slidingly connected to an “L” shaped plate which is mounted to the support plate and a screwing rod threadedly connect to the limit plate and support plate.
Claim 3 discloses the storage mechanism comprising a connecting box fixedly mounted on upright posts of the base; a threaded rod rotatably mounted at a top of the connecting box; a threaded sleeve set on the threaded rod; a connecting plate fixedly mounted on at least one side of the support plate, one side of the connecting plate extending outside of the protective box, the connecting plate being securely connected to the threaded sleeve; a drive mechanism provided on the connecting box for driving the threaded rod.
The prior art cited teaches the limitations of claim 1, but does not teach the limitations of claim 3. The embodiment taught by the prior art that is obvious over claim 1, would not have been obvious to modify or change in a manner similar to the limitations of claim 3. There is no prior art that teaches the limitations of claims 1 and 3, either singularly or in combination.
Claims 4-9 depend on claim 3.
