II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 11,274,520 - "Apparatus, System and Process for Regulating a Control Mechanism of a Well," issued March 15, 2022
The Invention Explained
- Problem Addressed: The patent describes the risks inherent in complex, multi-well oil and gas operations, where miscommunication or mistakes can lead to the unsafe actuation of wellhead valves. Such accidents can cause expensive downtime (e.g., closing a valve on a downhole tool) or create dangerous conditions, such as the release of high-pressure fluids (Compl. ¶24; ’520 Patent, col. 3:1-31).
- The Patented Solution: The invention provides a system for regulating a wellhead control mechanism, either indirectly (e.g., through a physical interlock) or directly (e.g., via a remote controller circuit). The system is designed to assess whether it is safe to actuate a valve and can use a "handshake protocol" to verify safety before allowing a locked-out mechanism to be actuated (’520 Patent, col. 2:31-56, col. 2:50-56). The abstract describes an apparatus with a moveable body that can physically interfere with a valve actuator to prevent its operation, thereby locking the valve in a specific position (’520 Patent, Abstract).
- Technical Importance: This technology aims to replace or supplement human-centric safety protocols with an automated or semi-automated system that integrates real-time operational data to prevent catastrophic errors on a busy well pad (Compl. ¶¶ 25, 27).
Key Claims at a Glance
- The complaint asserts independent claims 1 and 11 (Compl. ¶62).
- Independent Claim 1 recites a valve assembly comprising:
- a valve body for housing a valve;
- an actuator positioned remotely from the valve body and operatively coupled to the valve for controlling its position; and
- a controlled actuator configured to receive commands for moving the actuator.
 
- Independent Claim 11 recites a system for controlling the orientation of a valve, comprising:
- a valve assembly (including a valve body, a remote actuator, and a controlled actuator); and
- a controller configured to send commands to the controlled actuator.
 
- The complaint reserves the right to assert additional claims (Compl. ¶62).
U.S. Patent No. 11,608,708 - "Apparatus, System and Process for Regulating a Control Mechanism of a Well," issued March 21, 2023
The Invention Explained
- Problem Addressed: Similar to the ’520 Patent, this patent addresses the operational dangers on well pads with multiple wells and service companies. It seeks to prevent accidents caused by unsafe valve actuation, such as closing a valve at the wrong time or under unsafe pressure conditions (’708 Patent, col. 3:1-35).
- The Patented Solution: The invention is a process for regulating a wellhead control mechanism. The core of the patented process involves "locking out" a control mechanism to prevent its actuation and then performing a "handshake protocol" to determine if it is safe to release the lock and actuate the mechanism (’708 Patent, col. 2:50-56). This protocol involves communication and confirmation steps to eliminate miscommunication among personnel before enabling a potentially hazardous operation (’708 Patent, Abstract; Compl. ¶¶ 25-27).
- Technical Importance: The process provides a clear technical improvement over prior safety procedures by creating a verifiable, multi-step confirmation loop before allowing a critical valve operation to proceed (Compl. ¶26).
Key Claims at a Glance
- The complaint asserts independent claims 1 and 24 (Compl. ¶79).
- Independent Claim 1 recites a process for regulating a wellhead control mechanism, comprising the steps of:
- locking out the wellhead control mechanism so that it cannot actuate; and
- performing a handshake protocol to determine if the locked-out wellhead control mechanism can be released and then actuated.
 
- Independent Claim 24 recites a process for regulating a wellhead control mechanism, comprising:
- locking out the wellhead control mechanism; and
- performing a handshake protocol where an initiator signal is sent by a first user to a controller circuit, and the controller circuit sends a confirmatory signal back to the first user when the mechanism can be unlocked safely.
 
- The complaint reserves the right to assert additional claims (Compl. ¶79).
III. The Accused Instrumentality
Product Identification
Defendant’s Freedom Series Completion System ("FSCS"), which includes the FS Valve, the FS iControl software, and the FS Control Center (Compl. ¶¶ 33, 36-37).
Functionality and Market Context
The FSCS is described as a "remotely operated completion system" featuring an "integrated multi-chamber hydraulic valve" (Compl. ¶33). The complaint alleges the system is "fully automated and IoT-enabled," allowing for remote monitoring and control of wellhead operations from outside the hazardous "redzone" (Compl. ¶¶ 35, 37). A screenshot from a promotional video shows the "FS Control Center" with "REMOTE SOFTWARE" controlling an "FS Valve" and "FS Latch" on a wellhead (Compl. ¶34). Another visual shows the "FS iControl" software dashboard, which displays real-time status and pressure readings for various valves, providing an interface for monitoring and control (Compl. ¶36). A diagram from another video explicitly states the "FS Control Center remotely closes FS Valve" (Compl. ¶38). The complaint alleges these products are direct competitors to Plaintiff's systems and have resulted in lost sales for Plaintiff (Compl. ¶¶ 40-41).
IV. Analysis of Infringement Allegations
’520 Patent Infringement Allegations
| Claim Element (from Independent Claim 11) | Alleged Infringing Functionality | Complaint Citation | Patent Citation | 
| a valve assembly, the valve assembly comprising: (i) a valve body... (ii) an actuator... positioned remotely from the valve body... (iii) a controlled actuator that is configured to receive commands for moving the actuator | The FSCS includes the FS Valve (valve body and actuator) and the FS Control Center, which is positioned remotely and acts as a controlled actuator (Compl. ¶38). A diagram shows the "FS Control Center remotely closes FS Valve" (Compl. ¶38). | ¶¶33, 35, 38 | col. 38:8-20 | 
| a controller that is configured to send commands to the controlled actuator | The FS iControl software package and FS Control Center function as a controller, allowing for "off-site monitoring and control" and sending commands to the FSCS to perform actions like closing the FS Valve (Compl. ¶¶ 36-38). | ¶¶36-38 | col. 38:50-53 | 
Identified Points of Contention
- Scope Questions: A central question may be whether the combination of Defendant's FS Control Center and FS iControl software meets the definition of a "controller" that sends "commands" to a "controlled actuator" as those terms are understood in the patent. The analysis will depend on whether Defendant's remote operation is merely a switch activation or if it involves the specific command-and-control logic described in the patent.
- Technical Questions: What is the precise mechanism of the "FS Control Center"? The complaint alleges it "remotely closes" the valve, but the technical means by which it does so will be critical to determining if it functions as the claimed "controlled actuator."
’708 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation | 
| locking out the wellhead control mechanism so that it cannot actuate | The complaint alleges that Plaintiff's technology, which it claims Defendant used, involves enabling a "'locked out' well control mechanism from being actuated" to ensure safety (Compl. ¶27). The infringement allegation rests on the theory that Defendant's system performs this function. | ¶¶26-27 | col. 2:50-52 | 
| performing a handshake protocol to determine if the locked out wellhead control mechanism can be released and then actuated | The complaint alleges that in an April 2023 article, Defendant "discloses the use of a digital handshake which 'is tied to each person authorized to use the system'" (Compl. ¶52). Plaintiff alleges this functionality was derived from its trade secrets and performs the claimed protocol (Compl. ¶¶ 25, 54). | ¶¶25, 52, 54 | col. 2:52-56 | 
Identified Points of Contention
- Scope Questions: The case may turn on the definition of "handshake protocol." Does a user-authorization feature, as allegedly described in Defendant's article, constitute the safety-verification and multi-party confirmation protocol described in the patent's specification?
- Technical Questions: What is the specific functionality of Defendant's alleged "digital handshake"? The complaint's allegation is based on a marketing publication, and the actual implementation in the FSCS will be subject to discovery and technical examination. The question for the court will be whether this feature performs the steps of the claimed process.
V. Key Claim Terms for Construction
For the ’708 Patent
- The Term: "handshake protocol"
- Context and Importance: This term is the core of the asserted process claims and is highlighted in the complaint as a "novel technological solution" that Plaintiff alleges Defendant misappropriated (Compl. ¶25). The interpretation of this term will be dispositive for the infringement analysis of the ’708 Patent. Practitioners may focus on this term because its definition will determine whether Defendant’s user-authorization feature falls within the claim scope.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The claims themselves define the protocol's purpose generally as being "to determine if the locked out wellhead control mechanism can be released and then actuated" (’708 Patent, cl. 1). This functional language could support an interpretation covering any electronic-based confirmation process for unlocking a device.
- Evidence for a Narrower Interpretation: The specification provides more specific examples, such as a process involving an "initiator signal," "confirmatory signals," and "commands" for verification (Compl. ¶¶ 26-27, citing the patent application). One embodiment describes an "authority loop" requiring approval from multiple distinct parties (e.g., wireline operator, frac operator, oil company representative) before an action is approved (’708 Patent, Fig. 21). This could support a narrower construction requiring a multi-user, interactive confirmation process, not just a single-user authorization.
 
VI. Other Allegations
- Indirect Infringement: The complaint alleges that Defendant induces infringement by "instructing, directing, training, and/or requiring" customers and users of the FSCS to operate it in an infringing manner, including through advertising and distributing guidelines and instructions (Compl. ¶¶ 71, 73, 88, 90).
- Willful Infringement: The complaint alleges that Defendant had pre-suit knowledge of the asserted patents. The basis for this allegation includes the parties' prior collaboration in June 2020, patent marking on Plaintiff's products, and Defendant's own filing of a patent lawsuit in May 2023, which Plaintiff argues demonstrates Defendant's awareness of the patent landscape in this specific technical field (Compl. ¶¶ 65-67, 82-84).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of definitional scope: Can the term "handshake protocol," which the patent specification links to a multi-user safety verification process, be construed to cover the "digital handshake" allegedly used in Defendant's system, which the complaint connects to user authorization?
- A central evidentiary question will be one of causation and copying: The complaint intertwines patent infringement with trade secret misappropriation, alleging that Defendant's accused functionality was developed using confidential information from Plaintiff. While not a formal element of patent infringement, the evidence of the parties' prior collaboration will likely influence the narrative and context of the infringement analysis, particularly concerning the "handshake protocol" feature.
- A key technical question will be one of functional operation: Does the accused FSCS, particularly its FS iControl software and FS Control Center, actually perform the specific steps of "locking out" a control mechanism and executing a safety verification protocol as claimed, or is there a fundamental mismatch between the system's remote-control features and the patented processes?
