Patent Analyst Summary: U.S. Patent No. 12,031,784

Date of Analysis: April 26, 2026

A review of U.S. Patent No. 12,031,784, titled "Adapted forced reset trigger," has been conducted based on information from the USPTO database. Additionally, a search of CAFC 2026 dockets for this patent number was performed.

Patent Details:

• Title: Adapted forced reset trigger
• Assignee: ABC IP, LLC
• Inventor: Lawrence DeMonico
• Filing Date: November 4, 2022
• Issue Date: July 9, 2024
• Abstract: In a forced reset trigger mechanism, an extended trigger member locking device is provided. This device has a locking member that can move between a first position, where it prevents the trigger member from being pulled, and a second position, where it allows the trigger member to move. The locking member is designed to be movably supported by a frame and features a generally upward extension that makes contact with a surface of a bolt carrier to be actuated. The locking member includes a body portion that is movably supported and an upward extension portion that can move separately from the body, between an extended and a deflected position.

Litigation Search:

A search for "12031784" in the CAFC 2026 dockets did not yield any direct results. However, district court records indicate that U.S. Patent No. 12,031,784 is the subject of litigation in a case styled ABC IP, LLC v. Hoffman, for which a notice of appeal was filed in March 2026. This suggests the patent may be part of a future or ongoing CAFC case. The patent is also mentioned in a complaint analysis for ABC IP LLC v. Mars Trigger LLC filed in March 2026.

Plain-Language Overview of Independent Claims:

The patent contains one independent claim.

• Claim 1: This claim describes an extended locking device for a forced reset trigger. The core of the invention is a locking member that can shift between a position that locks the trigger and a position that unlocks it. This movement is initiated when a part of the locking device, an upward extension, is pushed by the firearm's bolt carrier. A key feature of this locking member is its two-part construction: a main body that moves and an upwardly extending part that can also deflect or move on its own, relative to the main body. This allows it to be actuated by the bolt carrier moving forward, but to also fold or deflect out of the way as the bolt carrier moves backward.

As a patent attorney, based on the information available as of April 26, 2026, U.S. Patent No. 12,031,784 is involved in ongoing litigation. The patent, titled "Adapted forced reset trigger," is part of a broader legal conflict concerning firearm technology known as "forced reset triggers" (FRTs).

Analysis of Prior Art Cited in U.S. Patent No. 12,031,784

As a technical patent analyst, I have reviewed the prior art citations for U.S. Patent No. 12,031,784, titled "Adapted forced reset trigger." The '784 patent, assigned to ABC IP, LLC, describes a locking member for a forced reset trigger with a deflectable upper portion. This feature is intended to allow the trigger to function in firearms with different internal dimensions, such as the AR-10 platform, where a standard locking bar would be too short to be actuated or would interfere with the bolt carrier's movement.

The analysis below details the most relevant prior art cited during the patent's prosecution and its potential impact on the claims of the '784 patent under 35 U.S.C. § 102.

Key Cited References

The primary inventive concept of the '784 patent revolves around a two-piece, hinged, or otherwise deflectable locking member that interacts with the bolt carrier. The most relevant prior art teaches the fundamental concepts of forced reset triggers and various safety and locking mechanisms.

1. U.S. Patent No. 10,514,223 B1

• Full Citation: US 10,514,223 B1, "Firearm trigger mechanism," Inventor: Jeffrey Cooper Rounds, Assignee: Wolf Tactical LLC, Publication Date: December 24, 2019, Filing Date: September 27, 2018.
• Brief Description: This patent is foundational to the '784 patent and is explicitly incorporated by reference. It describes a forced reset trigger mechanism where the hammer, upon being reset by the bolt carrier, forces the trigger member back to its set position. It also discloses a locking bar that prevents the trigger from being pulled unless the bolt carrier is fully in battery.
• Potential Anticipation of Claims: This patent does not anticipate the core claims of the '784 patent. While it establishes the environment of a forced reset trigger with a locking member, the locking member described is a single, rigid component. The '784 patent's background section explicitly states that the design in the '223 patent is insufficient for certain firearm platforms like the AR-10 because a simple extension of the locking bar would lead to interference with the bolt carrier. Therefore, the '223 patent lacks the novel element of a "deflectable portion" that is "separately movable relative to the body portion" as claimed in independent claim 1 of the '784 patent.

2. U.S. Patent No. 11,346,627 B1

• Full Citation: US 11,346,627 B1, "Forced reset semiautomatic trigger with sliding blocking bar," Inventor: Lawrence DeMonico, Assignee: ABC IP, LLC, Publication Date: May 31, 2022, Filing Date: February 8, 2022.
• Brief Description: This patent, also from the inventor of the '784 patent, describes a forced reset trigger that uses a sliding locking member instead of a pivoting one. This sliding bar is actuated by the bolt carrier to lock and unlock the trigger. The '784 patent itself mentions that its deflectable extension concept could be adapted to a sliding locking member like the one shown in the '627 patent.
• Potential Anticipation of Claims: This patent does not anticipate the claims of the '784 patent. The locking member in the '627 patent, while different from the '223 patent (sliding vs. pivoting), is still a unitary, non-deflecting component in the context of the upward extension. It does not teach or suggest the two-piece, deflectable/hinged construction that is the central innovation of the '784 patent's claims.

3. U.S. Patent No. 7,398,723 B1

• Full Citation: US 7,398,723 B1, "Trigger forward displacement system and method," Inventor: Brian A. Blakley, Publication Date: July 15, 2008, Filing Date: April 25, 2003.
• Brief Description: The Blakley patent discloses a system to increase the cyclic rate of a semi-automatic firearm by using the bolt carrier's movement to act on a pivoting cam, which in turn forces the trigger forward. This is a form of a forced reset mechanism.
• Potential Anticipation of Claims: This patent does not anticipate the claims of the '784 patent. While it deals with interaction between the bolt carrier and a trigger mechanism component to achieve a reset, it does not describe a locking member that prevents the trigger from being pulled. More specifically, it does not disclose a locking member with a body portion and a separately movable, upwardly extending deflectable portion as recited in claim 1 of the '784 patent.

4. U.S. Patent No. 9,151,557 B2

• Full Citation: US 9,151,557 B2, "Automatic sear assembly for a rifle," Assignee: Sig Sauer, Inc., Publication Date: October 6, 2015, Filing Date: May 17, 2013.
• Brief Description: This patent describes an automatic sear assembly for a rifle that includes a sear trip actuated by the bolt carrier. The sear trip has a feature (a spring-loaded pawl) that allows the bolt carrier to pass over it in one direction (rearward) but causes actuation when the bolt carrier moves forward into battery.
• Potential Anticipation of Claims: This patent presents a closer, though still distinct, concept. It teaches a one-way actuation mechanism involving the bolt carrier. However, this mechanism is part of an automatic sear for controlling the timing of a hammer in automatic fire, not a locking member for a semi-automatic forced reset trigger that prevents the trigger itself from moving. While it shows a component with a form of one-way deflection, its function and integration into the trigger mechanism are different from what is claimed in the '784 patent. It does not disclose a "locking member that is movable between a first position in which it locks a trigger member against pulling movement and a second position where it does not restrict movement," which is a key limitation of claim 1.

Conclusion

Based on the analysis of the cited prior art, none of the references appear to anticipate the claims of U.S. Patent No. 12,031,784 under 35 U.S.C. § 102. The key innovation recited in independent claim 1—a trigger locking member with a main body and a separately movable, deflectable upper portion designed to interact with the bolt carrier in two different ways depending on its direction of travel—is not taught by the cited art. The foundational '223 and '627 patents disclose forced reset triggers with unitary locking members, and the '784 patent's invention is presented as a solution to the specific dimensional problems their designs would face in certain firearms. Other references, like Blakley ('723) and Sig Sauer ('557), describe different mechanisms for interacting with a bolt carrier but do not disclose the specific claimed structure and function of the '784 patent's locking member.

Analysis of Obviousness for U.S. Patent No. 12,031,784 under 35 U.S.C. § 103

As a technical patent analyst, I have reviewed U.S. Patent No. 12,031,784 ('784 patent) and its cited prior art to assess the patentability of its claims under the obviousness standard of 35 U.S.C. § 103. The analysis focuses on whether a person having ordinary skill in the art (POSITA) would have been motivated to combine the teachings of existing prior art references to arrive at the claimed invention with a reasonable expectation of success.

The central innovation claimed in the '784 patent is a trigger locking member for a forced reset trigger mechanism that includes a main body and a separately movable, "upwardly extending deflectable portion." (Claim 1). This design solves a specific problem articulated in the patent's background section: adapting a forced reset trigger with a locking bar, like the one in U.S. Patent No. 10,514,223 ('223 patent), to firearm platforms with different internal geometries, such as the AR-10. In such platforms, a simple, rigid locking bar would be too short to be actuated by the bolt carrier or, if lengthened, would interfere with the bolt carrier's rearward travel.

Based on the cited art, a strong argument for obviousness can be constructed by combining the foundational forced reset trigger mechanism of the '223 patent with the one-way actuation mechanism taught by U.S. Patent No. 9,151,557 ('557 patent).

Primary Combination of References for Obviousness

A combination of U.S. Patent No. 10,514,223 ('223 patent) and U.S. Patent No. 9,151,557 ('557 patent) would render the claims of the '784 patent obvious.

• U.S. Patent No. 10,514,223 (Rounds): This patent, which is incorporated by reference into the '784 patent, teaches the foundational elements of the claimed invention. It discloses a forced reset trigger mechanism that includes a "locking member (bar) 12 [that] locks the trigger member 14 and prevents it from being pulled any time the bolt carrier assembly 16 is not in the substantially in-battery position." (Description of '784 patent, referencing the '223 patent). The '223 patent thus provides the starting point: a semi-automatic forced reset trigger with a pivoting locking member actuated by the bolt carrier. The only missing element is the "upwardly extending deflectable portion that is separately movable relative to the body portion" (Claim 1).

• U.S. Patent No. 9,151,557 (Sig Sauer): This patent addresses a similar problem of bolt carrier interaction within a firearm. It discloses an automatic sear assembly with a spring-loaded pawl, which is a one-way actuation mechanism. This pawl is designed to be actuated by the bolt carrier moving in one direction (forward) but pivots out of the way to allow the bolt carrier to pass over it when moving in the opposite direction (rearward). This is functionally analogous to the "deflectable portion" of the '784 patent's locking member. While the '557 patent applies this concept to an automatic sear, the principle of a hinged, spring-loaded component that allows for one-way actuation by a reciprocating bolt carrier is clearly taught.

Motivation to Combine

A person of ordinary skill in the art (POSITA), such as a firearm designer or engineer, would have been motivated to combine the teachings of the '223 and '557 patents to solve the known problem of adapting the forced reset trigger to different firearm platforms.

1. Known Problem: The '784 patent itself establishes the problem to be solved. A POSITA attempting to install the trigger from the '223 patent into an AR-10 or similar firearm would immediately encounter the issue described: the standard locking bar is too short. The most straightforward solution would be to extend the locking bar upwards.

2. Predictable Failure: Upon extending the rigid locking bar of the '223 patent, the POSITA would find that this modification creates a new problem—mechanical interference with the bolt carrier during its rearward cycle, leading to a malfunction. This is a predictable outcome based on the known geometry of the components.

3. Search for a Solution: Faced with this interference problem, the POSITA would look for known mechanical solutions for one-way actuation by a reciprocating part. The mechanism in the '557 patent provides a direct and well-understood solution to this exact type of problem. It teaches the use of a hinged, spring-biased element (a pawl) that engages a component (the bolt carrier) in one direction of travel and deflects to allow passage in the other.

4. Simple Application: The motivation to combine would be high because applying the one-way hinge concept from the '557 patent's sear trip to the '223 patent's locking bar is a straightforward mechanical adaptation. The POSITA would be motivated to replace the now-problematic rigid upper portion of the extended locking bar with a hinged, deflectable equivalent, as taught by the '557 patent. This combination would be expected to allow the locking bar to be tall enough to be actuated by the bolt carrier moving into battery, while also folding out of the way during the bolt carrier's rearward travel, thus resolving the interference issue with a reasonable expectation of success.

Conclusion on Obviousness

The independent claim of the '784 patent recites a locking member with a body and a separately movable, deflectable upper portion. The '223 patent teaches all elements of this claim except for the deflectable portion. The '557 patent teaches the missing element—a hinged, one-way actuation mechanism designed for interaction with a bolt carrier.

A POSITA, starting with the forced reset trigger in the '223 patent and seeking to adapt it for use in an AR-10, would be directly motivated to lengthen the locking bar. This would predictably create an interference problem, which would, in turn, motivate the POSITA to incorporate a known one-way actuation mechanism, such as the one disclosed in the '557 patent. This combination of known elements from the prior art to solve a known problem renders the claims of U.S. Patent No. 12,031,784 obvious under 35 U.S.C. § 103.

Defensive Disclosure Document for U.S. Patent No. 12,031,784

Publication Date: April 27, 2026
Subject: Derivative Embodiments and Obvious Variations of a Locking Member with a Separately Movable, Deflectable Portion for Forced Reset Trigger Mechanisms.
Reference Patent: U.S. Patent No. 12,031,784 B1 ("the '784 patent")

This document discloses a series of derivative inventions and technical variations based on the core principles described in the '784 patent. The purpose of this disclosure is to place these variations into the public domain, thereby establishing prior art against future patent applications claiming these or similar concepts. The core concept of the reference patent is a trigger locking member comprising a main body and an upwardly extending, separately movable deflectable portion for one-way actuation by a reciprocating bolt carrier.

Derivations Based on Independent Claim 1

Core Claim 1: A locking member for a forced reset trigger movable between a locked and unlocked position, actuated by a bolt carrier, and having a main body and an upwardly extending deflectable portion that is separately movable relative to the body.

Axis 1: Material & Component Substitution

1. Magnetically-Repelled Deflectable Member

• Enabling Description: The hinged, upwardly extending deflectable portion and its corresponding mechanical spring (e.g., torsion spring 28) are replaced with a non-contact magnetic system. The deflectable portion is fabricated from a ferrous material or embedded with a permanent magnet (e.g., Neodymium N52). The main body of the locking member houses a second, opposing permanent magnet. The poles are oriented to create a repelling force, which biases the deflectable portion toward its extended, upright position. Upon contact with the rearward-traveling bolt carrier, the deflectable portion pivots against this magnetic repulsion, then snaps back to the extended position once the carrier has passed. This eliminates mechanical wear associated with a spring and pivot pin.

2. Shape-Memory Alloy (SMA) Deflectable Member

• Enabling Description: The entire upwardly extending portion is fabricated from a shape-memory alloy, such as Nickel Titanium (Nitinol). The "memory" state of the alloy is set to the upright, extended position. The deflectable portion is engineered to be in its malleable, martensitic phase at the firearm's standard operating temperature. Contact from the bolt carrier deforms the member into the deflected position. The slight temperature increase from the friction of the carrier's passage, combined with the material's superelastic properties, causes an immediate phase transformation back to the rigid, austenitic state, returning the member to its upright "memory" position. This creates a solid-state "hinge" with no moving parts.

3. Laminated Composite Deflectable Member with Integral Leaf Spring

• Enabling Description: The deflectable portion is not a separate, hinged component but is monolithically integrated with the main body. The entire locking member is fabricated from a laminated composite, such as layers of carbon fiber and a high-impact polymer (e.g., PEEK). The upwardly extending portion is designed with a localized reduction in thickness or a specific fiber orientation (e.g., 0/90 layup in the body, +/- 45 layup at the flex point) to create an integral leaf spring. This section is rigid enough to transfer force when pushed forward by the bolt carrier but flexible enough to bend rearward when contacted from the front, then snap back to its original position.

Axis 2: Operational Parameter Expansion

4. Cryogenic/High-Temperature Operation

• Enabling Description: For operation in extreme temperature environments (-70°C to +300°C), the locking member and its components are fabricated from materials with low thermal expansion and high durability across this range. The body and deflectable portion are machined from a cobalt-chrome alloy (e.g., Stellite 6) or a precipitation-hardened stainless steel (e.g., 17-4 PH in H900 condition). The pivot pin is replaced by a ceramic pin (e.g., silicon nitride), and the torsion spring is fabricated from Inconel 718 to prevent loss of temper at high temperatures and brittle fracture at cryogenic temperatures.

5. Nanoscale Mechanical Latching System

• Enabling Description: The invention is scaled down for use in micro-electro-mechanical systems (MEMS). The locking member is a silicon cantilever etched from a substrate, measuring micrometers in length. The "deflectable portion" is a nano-etched flexible tip. The "bolt carrier" is a reciprocating actuator on the MEMS device. Actuation is achieved through electrostatic force. When the actuator moves forward, it pushes the entire cantilever (locking member) to unlock a micro-gear. When the actuator retracts, it brushes past the flexible tip, which deflects without moving the main cantilever body. This enables one-way mechanical logic gates in MEMS devices.

6. Aerospace: One-Way Latch for Deployable Solar Arrays

• Enabling Description: The mechanism is adapted as a one-way retention latch for deployable structures on satellites, such as solar panels or antennas. A reciprocating deployment boom acts as the "bolt carrier." During deployment, the boom pushes forward against the locking member's deflectable portion, causing the entire member to pivot and release the panel from its stowed position. Should the boom need to be retracted for testing or to clear a jam, it can move rearward past the locking member, which will deflect out of the way without re-latching the panel. This prevents accidental stowing during a partial retraction.

7. Agricultural Tech: Gate Latch for Automated Herding Systems

• Enabling Description: The mechanism is used as a gate latch in an automated livestock sorting facility. An automated pusher arm (the "bolt carrier") guides an animal toward a gate. The arm pushes the locking member to unlatch the gate, allowing the animal to pass through. Once the animal is through, the arm retracts. As it retracts, its lower edge contacts the deflectable portion of the locking member, which folds away, allowing the arm to pass without re-engaging the gate's lock. The gate can then be closed by a separate spring mechanism, ready for the next animal.

8. Consumer Electronics: Battery Ejection Latch

• Enabling Description: A miniaturized version of the mechanism is used as a battery ejection latch in a ruggedized device. A sliding ejector button ("bolt carrier") is pressed. Its forward motion engages the rigid aspect of the locking member, causing it to pivot and release the battery. When the user releases the button, a spring retracts it. During retraction, the button slides over the deflectable portion of the latch, which moves out of the way without re-locking the battery, ensuring a clean ejection cycle with a single press.

Axis 4: Integration with Emerging Tech

9. IoT-Monitored Locking Member with Predictive Maintenance

• Enabling Description: The pivot pin of the deflectable portion is replaced with a smart pin containing a piezoelectric strain gauge. The main body of the locking member houses a microcontroller and a low-power LoRaWAN transmitter. Each time the deflectable portion is actuated by the bolt carrier, the strain gauge registers the impact and pivot. The microcontroller counts these actuations as "cycles." This data is transmitted periodically to a central monitoring system. An AI model uses the cycle count and the force profile of the impacts to predict mechanical fatigue and schedule preventative maintenance before the component fails.

10. Blockchain-Verified Component Lifecycle Tracking

• Enabling Description: The locking member is serialized with a physically unclonable function (PUF) or a QR code etched at the time of manufacture. Its material composition, manufacturing date, and initial QC tests are recorded as the genesis block on a private blockchain. Each significant event in its lifecycle—installation into a trigger assembly (recorded by the manufacturer), transfer to a distributor, and cycle counts from an integrated IoT sensor—is recorded as a new, immutable transaction on the blockchain. This provides a cryptographically secure audit trail, preventing counterfeiting and verifying the component's history and use intensity for warranty and safety analysis.

Axis 5: The "Inverse" or Failure Mode

11. Fail-Safe Locking Member with Shear Pin

• Enabling Description: The deflectable portion is attached to the main body not with a permanent pivot pin, but with a calibrated shear pin made from a softer material (e.g., brass or a specific polymer). Under normal operation, the pin serves as a standard pivot. However, if the bolt carrier moves with excessive force or becomes jammed against the deflectable portion (a failure condition), the shear pin is designed to fracture. Upon fracturing, the deflectable portion either falls away or swings freely, preventing the transfer of catastrophic force to the main locking member or trigger housing. This prioritizes the integrity of the larger assembly by sacrificing a small, easily replaceable component.

Combination Prior Art Scenarios

1. Combination with IEEE 802.15.4 for Wireless Mesh Network Monitoring

• Disclosure: The locking member, equipped with an integrated cycle counter and strain sensor as described in derivative #9, uses an IEEE 802.15.4-compliant radio transceiver instead of LoRaWAN. This allows multiple locking members within a facility (e.g., an armory or manufacturing plant) to form a low-power, self-healing mesh network. Data regarding cycle count, operational stress, and device status is relayed from one unit to another until it reaches a central gateway. This is more robust than a star network topology in environments with significant RF interference.

2. Combination with an Open-Source RISC-V Microcontroller Core

• Disclosure: The onboard microcontroller for processing sensor data and managing wireless communication (as in derivative #9) is based on an open-source RISC-V instruction set architecture (ISA). Specifically, a low-power core like the PULPino or VexRiscv is used. This decouples the smart-component's functionality from proprietary silicon, allowing for greater customization, security auditing, and a more resilient supply chain for the electronic components of the safety-critical device.

3. Combination with STEP (ISO 10303) for Digital Twin Modeling

• Disclosure: The CAD model of the locking member and its deflectable portion is exported using the ISO 10303 standard (STEP protocol, specifically AP242 for managed model-based 3D engineering). This open-standard file is used as the basis for a "digital twin" of the physical component. Real-time data on cycle count and material stress, gathered via IoT sensors, is fed into a physics-based simulation model derived from the STEP file. This allows for a continuously updated digital twin that accurately reflects the physical state and remaining service life of the component, enabling advanced fleet management and predictive failure analysis based on an open data standard.
