More particularly, the present invention relates to determining faults in heating, ventilation and air conditioning (HVAC) systems.” Paragraph 0002)

At step 202 the HVAC component is monitored by collecting data relevant to a series of periods of operation of the HVAC component, for example the data may be room temperature values and the HVAC component may be a boiler 140. The temperature values may be values recorded during times when the boiler 140 is turned on. They may also include values recorded before the boiler 140 has been turned on and after the boiler has been turned off.” Paragraph 0091)

The temperature values may be values recorded during times when the boiler 140 is turned on. They may also include values recorded before the boiler 140 has been turned on and after the boiler has been turned off.” Paragraph 0091)
determining a sample value for each of the sample intervals, each sample value representing a rate of change of the environmental parameter in the respective interval.

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.
Claims 6 and 14 are rejected under 35 U.S.C. 103 as being unpatentable over
U.S. Patent Application Publication No. 2019/0264936 (Bailey) in view of
U.S. Patent Application Publication No. 2020/0226697 (Han).
Claim 6:
Bailey does not explicitly describe a histogram and related processing as described below. However, Han teaches the histogram and related processing as described below.
The cited prior art describes the method of claim 1, further comprising:
for each of a plurality of bins, each bin being associated with a range of sample values, determining a number of the sample values that fall within the associated range to generate histogram data; (Han: see the histogram of energy cost versus temperature as illustrated in figure 4; “The insight preview window 411 may display information identifying the month, the billing amount for that month, and the average temperature for that month. The insight preview window 411 may be provided for display in an overlay at a position that overlaps a location on the energy histogram, or at a position adjacent to the selected data point of the energy histogram.” Paragraph 0071; “In other aspects, the billing advisor engine 250 may determine an energy load curve shape associated with the energy consumption data of an energy user. In this respect, the billing advisor engine 250 may identify respective sections of the energy load curve shape, and map the sections to respective types of loads (e.g., oven element, refrigerator, etc.) for identifying the source of energy consumption. In some examples, the energy load curve shape is a two-dimensional histogram identifying the amount of energy consumption (e.g., kilowatt hour(s)) over time (e.g., seconds, minute(s), hour(s), etc.).” paragraph 0041)
fitting a curve to the histogram data; and (Han: see the curve of temperature data to the energy data as illustrated in figure 4; “In other aspects, the billing advisor engine 250 may determine an energy load curve shape associated with the energy consumption data of an energy user. In this respect, the billing advisor engine 250 may identify respective sections of the energy load curve shape, and map the sections to respective types of loads (e.g., oven element, refrigerator, etc.) for identifying the source of energy consumption. In some examples, the energy load curve shape is a two-dimensional histogram identifying the amount of energy consumption (e.g., kilowatt hour(s)) over time (e.g., seconds, minute(s), hour(s), etc.).” paragraph 0041)
detecting a change in HVAC performance based on a change over time in at least one parameter of the curve. (Han: see the home diagnosis including heating and energy saving tips as illustrated in figure 5; “generating an interface comprising a plurality of insights that correspond to the one or more energy consumption factors, the plurality of insights identifying one or more explanations as to why the billing amount of the utility bill exceeded a cost expectation of the second user; mapping at least a portion of the utility bill to the interface; and providing the interface for display, the plurality of insights being displayed based on one or more interactions between the first user and the interface.” Paragraph 0004; “For example, the processor 236, using the disaggregation engine 248, performs disaggregation of HVAC energy usage based on heating coefficients and cooling coefficients.” Paragraph 0056; “The energy consumption analytics system 660 also may be in communication with a third party weather service, such as the National Weather Service (not shown). For example, the energy consumption analytics system 660 may receive corresponding outdoor temperatures from the third party weather service via the network 650 (e.g., e-mails, downloaded FTP files, and XML feeds). In this respect, the energy consumption analytics system 660 may use weather data from the third party weather service to determine a projected billing amount for a particular billing period, and identify any changes in the projected billing amount relative to a previous billing cycle due to weather patterns identified in the weather data. For example, forecasted weather conditions (e.g., the temperature, the humidity, the barometric pressure, precipitation, etc.) may indicate that an energy user's HVAC system is likely to be in greater use, thereby likely to cause an increase in the energy user's energy load curve. The energy consumption analytics system 660 may notify the energy user of insight information relating to a billing amount of an inquired utility bill through a follow-up communication (or an energy usage alert notification).” Paragraph 0080)
One of ordinary skill in the art would have recognized that applying the known technique of Bailey, namely, HVAC performance monitoring system, with the known techniques of Han, namely, energy usage analytics system for energy consumers, would have yielded predictable results and resulted in an improved system. Accordingly, applying the teachings of Bailey to analyze data to determine HVAC performance monitoring with the teachings of Han to analyze data to determine device energy usage would have been recognized by those of ordinary skill in the art as resulting in an improved HVAC monitoring system. In other words, the combination of references provides for analyzing various types of data using various analysis techniques for HVAC performance analysis based on the teachings of analyzing various types of data using various analysis techniques in Bailey and the teachings of using histograms to analyze data for energy monitoring in Han.
Claim 14:
Claim 14 is substantially similar to claim 6 and is rejected based on the same reasons and rationale.

for each of a plurality of bins, each bin being associated with a range of sample values, determining a number of the sample values that fall within the associated range to generate histogram data;
fitting a curve to the histogram data; and
detecting a change in HVAC performance based on a change over time in at least one parameter of the curve.
Claims 7, 15, and 18 are rejected under 35 U.S.C. 103 as being unpatentable over

U.S. Patent Application Publication No. 2020/0240662 (Picardi).
Claim 7:
Bailey does not explicitly describe audio data as described below. However, Picardi teaches the audio data as described below.
The cited prior art describes the method of claim 1,
wherein monitoring the HVAC system comprises collecting audio data, and (Picardi: see the collection of audio data as described in paragraph 0029; “audio data from microphones listening to the sounds produced by the HVAC system” paragraph 0029)
wherein the detection of a sample interval during which the HVAC system is active is based at least in part on the audio data. (Picardi: “The security system 160 can also train the machine-learning algorithm to detect and identify HVAC systems that have transitioned from an issue status to a healthy status. This indication produced by the machine-learning algorithm can indicate when HVAC service was performed in a monitored property. For example, the security system 160 can use data over a period of time that shows an HVAC system transitioning between an issue status and a healthy status. The data can include thermostat data over a period, such as 5 hours, outdoor temperature data over the period of time, and raw sensor data monitoring the HVAC system 146. The raw sensor data can be media data (e.g., video and photos) from one or more cameras that monitor the HVAC system, audio data from microphones listening to the sounds produced by the HVAC system, thermal imaging data from thermal sensors that monitor the HVAC system, data from the alarm panel 122 that show issues with the HVAC system 146, motion data from motion sensors surrounding the HVAC system 146, and lock sensor data from doors containing the HVAC system 146. Other sensor data can be provided from the monitored property. Additionally, the security system 160 can use data from house products to train the machine-learning algorithm. For example, the security system 160 can use data from outdoor temperature sensors, outdoor barometers, temperatures of various products in the monitored property 102, and data from a client device of the owner of the monitored property 102. The security system can also add the timestamp data to this transitioning training data to predict likelihoods that the system has transitioned from an issue state to a healthy state to predict likelihoods of transitions at particular times of the day. The training can be further based on HVAC systems at other monitored properties that have similar components. The training can include how long it takes for an HVAC system to transition to a health state after an issue has been detected.” Paragraph 0029) (Bailey: see the record analysis 520 as illustrated in figure 5 and as described in paragraphs 0128, 0129; “At step 520 the record is analysed to compute a set of parameters relating to the HVAC device (e.g. relating to its operation and/or performance) and/or relating to the premises which the HVAC device controls (e.g. relating to the environmental response of the monitored space), for that operational period.” Paragraph 0128; “Change in value of measured environmental characteristic over length of time for which the HVAC component is on (for example, rate of change of room temperature or other characteristic over activation period, such as rate at which the premises heats up when the boiler is on (e.g. measured in degrees change per hour))” paragraph 0129; “At step 204 the data collected in step 202 is analysed to identify patterns indicative of normal operation of the HVAC component, for example over a series of heating periods it may be possible to model normal operation of the house, such as a pattern showing how long it takes to increase the room temperature by a certain amount.” Paragraph 0092)
One of ordinary skill in the art would have recognized that applying the known technique of Bailey, namely, HVAC performance monitoring system, with the known techniques of Picardi, namely, a HVAC service performance system, would have yielded predictable results and resulted in an improved system. Accordingly, applying the teachings of Bailey to analyze data to determine HVAC performance monitoring with the teachings of Picardi to analyze data to monitor a HVAC system would have been recognized by those of ordinary skill in the art as resulting in an improved HVAC monitoring system. In other words, the combination of references provides for analyzing various types of data using various analysis techniques for HVAC performance analysis based on the teachings of analyzing various types of data using various analysis techniques in Bailey and the teachings of analyzing various types of data in Picardi.

18. (Original) The system of claim 17, wherein the additional parameter is at least one of audio data and voltage transient data.

U.S. Patent Application Publication No. 2010/0010679 (Kassel).
Claim 8:
Bailey does not explicitly describe electrical transient data as described below. However, Kassel teaches the electrical transient data as described below.
The cited prior art describes the method of claim 1,
wherein monitoring the HVAC system comprises collecting electrical transient data, and (Kassel: see the current flow as illustrated in figure 3 and as described in paragraphs 0008, 0124; see the data collected including current flow events, power events, current, and voltage as described in paragraphs 0008-0021)
wherein the detection of a sample interval during which the HVAC system is active is based at least in part on the electrical transient data. (Kassel: “Order, Ranking and Sequence Logic--as the previous blocks inputs change state, they are filtered for specific characteristics such as passing a threshold level, meeting a combinational-logic condition occurring in a particular sequence or exceeding some time duration previously established through settings made during initial configuration. Based on the configuration choices, values or options turned on or off sets up the criteria for which specific input(s) will be used to trigger an output event. Further, a weighting factor may be assigned to any selected inputs that will further influence the amount of change necessary to promulgate an output change. So based on such factors as repetition rate, duration or interval of said input's change, an outputs activity such as start-time, on duration, tie to another output or even ignoring action can be tailored. Ranking of which inputs will be the primary influence and which the tertiary, is orchestrated through a dynamic status ranking calculation using input activity placed through a programmable highpass fast averaging filter.” Paragraph 0125) (Bailey: see the record analysis 520 as illustrated in figure 5 and as described in paragraphs 0128, 0129; “At step 520 the record is analysed to compute a set of parameters relating to the HVAC device (e.g. relating to its operation and/or performance) and/or relating to the premises which the HVAC device controls (e.g. relating to the environmental response of the monitored space), for that operational period.” Paragraph 0128; “Change in value of measured environmental characteristic over length of time for which the HVAC component is on (for example, rate of change of room temperature or other characteristic over activation period, such as rate at which the premises heats up when the boiler is on (e.g. measured in degrees change per hour))” paragraph 0129; “At step 204 the data collected in step 202 is analysed to identify patterns indicative of normal operation of the HVAC component, for example over a series of heating periods it may be possible to model normal operation of the house, such as a pattern showing how long it takes to increase the room temperature by a certain amount.” Paragraph 0092)
One of ordinary skill in the art would have recognized that applying the known technique of Bailey, namely, HVAC performance monitoring system, with the known techniques of Kassel, namely, a HVAC monitoring system, would have yielded predictable results and resulted in an improved system. Accordingly, applying the teachings of Bailey to analyze data to determine HVAC performance monitoring with the teachings of Kassel to analyze data to monitor a HVAC system would have been recognized by those of ordinary skill in the art as resulting in an improved HVAC monitoring system. In other words, the combination of references provides for analyzing various types of data using various analysis techniques for HVAC performance analysis based on the teachings of analyzing various types of data using various analysis techniques in Bailey and the teachings of analyzing various types of data to monitor a HVAC system in Kassel.
