II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 10,683,716 - "Water Transfer Monitoring System And Method Of Use" (Issued June 16, 2020)
The Invention Explained
- Problem Addressed: The patent describes the manual supervision of temporary water transfer systems for oil and gas operations as inefficient, unsafe, and impractical for detecting problems like leaks or equipment malfunctions in a timely manner (Compl. ¶7; ’716 Patent, col. 2:1-5). These temporary systems often use "lay flat" hoses that are vulnerable to damage over long distances (Compl. ¶7; ’716 Patent, col. 1:55-61).
- The Patented Solution: The invention provides a method using self-contained, portable "skids" equipped with a plurality of sensors to monitor key parameters (e.g., flow rate, pressure, fuel level) at pump locations along the water line. These skids are designed to be easily installed and to transmit the collected data to a remote monitoring service, which can then alert an operator to abnormal conditions (’716 Patent, Abstract; col. 3:4-14).
- Technical Importance: This approach sought to replace frequent, manual inspections with automated, continuous remote surveillance, thereby reducing downtime, water loss, and operational risk in high-volume fracking operations (’716 Patent, col. 2:1-5).
Key Claims at a Glance
- The complaint asserts independent method claim 8 and reserves the right to assert others (Compl. ¶57).
- Claim 8 requires the steps of:
- Providing a self-contained and portable skid with a plurality of sensors.
- Installing the skid along a water transfer line by connecting its sensors to equipment.
- Taking a plurality of readings from the sensors.
- Transferring the readings to a remote data monitoring system.
- Installing a second self-contained and portable skid at a second location.
- Transmitting a second plurality of readings from the second skid to the remote system.
- Providing notifications to an operator regarding the readings.
U.S. Patent No. 11,725,648 - "Water Transfer Monitoring System And Method Of Use" (Issued August 15, 2023)
The Invention Explained
- Problem Addressed: The '648 patent addresses the same challenges as its parent '716 patent: the inefficiency and unreliability of manually supervising temporary water transfer systems in the field (Compl. ¶7; ’648 Patent, col. 2:1-5).
- The Patented Solution: This patent claims a system with a more modular architecture. It describes a configuration where sensor-gathering functions and control/communication functions are separated into distinct physical units: a "meter skid" and a "control panel skid" (’648 Patent, col. 7:3-10, FIG. 9). This allows for different deployment configurations where, for instance, a simple sensor package can be placed separately from the more complex control unit containing the battery, solar panel, and transceiver.
- Technical Importance: This modular design could offer greater deployment flexibility and potentially reduce the cost or complexity at each monitoring point by separating the core sensing equipment from the control and communications hardware (’648 Patent, col. 7:7-10).
Key Claims at a Glance
- The complaint asserts independent system claim 1 (Compl. ¶74).
- Claim 1 requires a system comprising:
- A remote computer.
- A water reservoir remote from a worksite, connected by a water transfer line.
- A first skid at a first location with one or more skid sensors.
- A control panel skid with a controller (to implement commands) and a transceiver (to communicate with the remote computer).
- A second skid at a second location.
- Data from the skids is transmitted to a remote data service for operator monitoring.
III. The Accused Instrumentality
Product Identification
- The "Accused Equipment" consists of Defendant’s water transfer automation systems, sold under the "Trojan" and "Sable Automation Solutions" brand names (Compl. ¶17). This includes portable "automation stands" (skids), associated sensors, and an "online platform" with software and mobile applications for remote monitoring and control (Compl. ¶¶ 18, 38).
Functionality and Market Context
- The Accused Equipment is alleged to use portable stands, placed at pump sites along a water transfer line, to monitor operational data such as engine speed and pump pressures (Compl. ¶¶ 18, 25). This information is transmitted to a central platform where it can be viewed on a smartphone or computer, enabling remote oversight and automated alerts (Compl. ¶¶ 26, 37). The complaint provides a screenshot of the accused mobile application, which displays data for a "PIT PUMP," "BOOSTER 1," and "BOOSTER 2" pump, suggesting a multi-point monitoring capability (Compl. ¶25, p. 10). The Defendant is alleged to market these systems as providing "seamless automation" (Compl. ¶23).

- Identified Points of Contention:
- Scope Questions: Does the term "first skid" and the separate term "control panel skid" require two physically distinct and separable units? The patent specification describes them as separate (’648 Patent, col. 7:6-9), while the complaint's visual evidence of the accused product appears to show a single, integrated "automation stand" (Compl. ¶19, p. 7).
- Technical Questions: What evidence shows that the Defendant’s singular "automation stand" contains the distinct functional modules corresponding to the claimed "first skid" (with sensors) and the "control panel skid" (with controller and transceiver) in a manner that satisfies the claim limitations?
V. Key Claim Terms for Construction
Term: "self-contained and portable skid" ('716 Patent, Claim 8)
- Context and Importance: This term defines the fundamental physical unit of the patented method. Its scope will determine the range of physical monitoring devices that could be used in an infringing manner.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The specification describes the skid functionally as being "pre-fabricated," "pre-wired," and "pre-programmed" for "minimal onsite installation and removal time" (’716 Patent, col. 3:17-20). This could support a broad definition covering any portable unit that accomplishes these functions.
- Evidence for a Narrower Interpretation: The patent figures depict specific physical arrangements of components on a frame (e.g., ’716 Patent, FIG. 4). A party could argue the term is implicitly limited to a single, integrated unit that packages the sensors and control equipment together as shown in the preferred embodiments.
Term: "first skid" and "control panel skid" ('648 Patent, Claim 1)
- Context and Importance: The construction of these terms is central to the infringement analysis for the '648 patent. The claim separately lists these two types of skids, suggesting they are distinct entities. Practitioners may focus on this term because the infringement allegation appears to read on an integrated product, while the patent seems to describe a modular, physically separate system.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: A plaintiff may argue that even within a single physical housing, the sensor package and the control/communication package are functionally distinct and therefore meet the definition of a "first skid" and a "control panel skid" respectively.
- Evidence for a Narrower Interpretation: The specification explicitly states that in an alternative embodiment, "the necessary components...are not all contained on a single, self contained skid, but rather on a control panel skid 903 and a meter skid 905" (’648 Patent, col. 7:6-9). This language provides strong support for an interpretation requiring physical separability, which could present a challenge to the infringement allegation if the accused "automation stand" is a single, indivisible unit.
VI. Other Allegations
- Indirect Infringement: The complaint alleges inducement of infringement, stating that Defendant instructs and encourages customers to use the Accused Equipment in an infringing manner through its software, mobile app, installation services, and other instructions (Compl. ¶¶ 60-62, 77-79). It also alleges contributory infringement on the basis that the Accused Equipment is especially made for infringing use and is not a staple article of commerce with substantial non-infringing uses (Compl. ¶¶ 63, 80).
- Willful Infringement: Willfulness is alleged based on Defendant’s purported knowledge of the patents. The complaint claims Defendant had knowledge of the '716 patent since at least May 18, 2023, upon receipt of a cease-and-desist letter, and of the '648 patent since at least November 7, 2023 (Compl. ¶¶ 45-46, 68, 85).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue for the '648 patent will be one of architectural scope: can the claim language requiring a distinct "control panel skid" and a "first skid" be construed to read on the Defendant’s allegedly integrated "automation stand"? Or does the patent’s explicit description of these as separate components limit the claim to a physically modular architecture that the accused product may not possess?
- For the '716 method patent, a key evidentiary question will be one of induced infringement: does the evidence show that Defendant’s instructions, marketing, and the functionality of its "online platform" affirmatively direct or require customers to deploy multiple skids and operate the system in a manner that performs the complete sequence of steps recited in method claim 8?
- A central factual dispute will likely concern the technical operation of the accused system. Discovery will be needed to determine if the single "automation stand" functions as a single integrated unit or contains distinct, separable modules that could map onto the claims of the '648 patent, potentially resolving the key question of architectural scope.
