II. Technology and Patent(s)-in-Suit Analysis

U.S. Patent No. 12,038,247 - Firearm Trigger Mechanism

  • Issued: July 16, 2024

The Invention Explained

  • Problem Addressed: The patent addresses the desire among some firearm users to increase the rate of semi-automatic fire, which is limited by the need to manually release and reset the trigger after each shot (Compl. ¶21; Compl. ¶22, Compl. ¶¶col. 1:20-54). Standard trigger mechanisms include a disconnector that prevents the hammer from following the bolt carrier, ensuring only one shot is fired per trigger pull Compl. ¶22
  • The Patented Solution: The invention is a trigger mechanism that provides multiple user-selectable modes, including a standard semi-automatic mode and a "forced reset" semi-automatic mode Compl. ¶24 In the forced reset mode, the rearward movement of the firearm's bolt carrier during the firing cycle interacts with a cam, which in turn "forces the trigger member to the set position" '247 Patent, abstract This mechanical reset allows the user to fire the next shot immediately once the action is in battery, without needing to manually release the trigger first Compl. ¶24 '247 Patent, col. 2:60-67
  • Technical Importance: The technology provides a mechanical method to significantly accelerate the potential rate of fire for a semi-automatic firearm, distinct from techniques like "bump firing."

Key Claims at a Glance

  • The complaint asserts independent claim 15 Compl. ¶45
  • The essential elements of claim 15 include:
    • A firearm trigger mechanism comprising a hammer, a trigger member, a disconnector, a cam, and a safety selector.
    • The mechanism is operable in a "standard semi-automatic" mode and a "forced reset semi-automatic" mode.
    • In standard mode, after firing, the disconnector catches the hammer, and the user "must manually release said trigger member" to reset the firearm for the next shot.
    • In forced reset mode, rearward bolt movement causes the cam to force the trigger member to the set position, while the safety selector "prevent[s] the disconnector hook from catching said hammer hook."
    • This allows the user to pull the trigger again to fire the firearm "without manually releasing said trigger member."
  • The complaint does not explicitly reserve the right to assert dependent claims for this patent.

U.S. Patent No. 12,031,784 - Adapted Forced Reset Trigger

  • Issued: July 9, 2024

The Invention Explained

  • Problem Addressed: The patent background explains that a forced reset trigger designed for one firearm platform (e.g., an AR-15) may be dimensionally incompatible with a related but different platform (e.g., an AR-10) '784 Patent, col. 1:21-44 Specifically, simply extending a locking member to interface with a differently-positioned bolt carrier could cause it to interfere with another part of the carrier as it cycles, rendering the device inoperable '784 Patent, col. 1:40-44
  • The Patented Solution: The invention provides a trigger locking member with an "upwardly extending deflectable portion that is separately movable relative to the body portion" '784 Patent, abstract '784 Patent, claim 1 This deflectable part is rigid enough to be actuated by the bolt carrier upon its return to battery, but it can hinge or fold out of the way to avoid interfering with the bolt carrier as it cycles to the rear '784 Patent, col. 2:1-10 '784 Patent, figs. 8-10
  • Technical Importance: This design allows a forced reset trigger mechanism to be adapted for use across multiple firearm platforms that share a common design heritage but have different critical dimensions.

Key Claims at a Glance

  • The complaint asserts independent claim 1 Compl. ¶60
  • The essential elements of claim 1 include:
    • An extended trigger member locking device for a forced reset trigger mechanism.
    • A locking member movable between a first (locked) position and a second (unlocked) position.
    • The locking member includes a "body portion" and an "upwardly extending deflectable portion."
    • This deflectable portion is "separately movable relative to the body portion between an extended position and a deflected position."
  • The complaint does not explicitly reserve the right to assert dependent claims for this patent.

U.S. Patent No. 12,529,538 - Safety Mechanism for Firearm

  • Issued: January 20, 2026
  • Technology Synopsis: The patent describes a safety mechanism for a firearm that uses a "cam selector" with multiple recesses, a lever, and a trigger Compl. ¶26 This combination allows the mechanism to operate in three distinct modes: a first standard mode, a second "active reset" mode where the cam rotates to move the trigger, and a third mode that prevents the trigger from being pulled '538 Patent, abstract
  • Asserted Claims: Independent claim 1 Compl. ¶75
  • Accused Features: The complaint alleges that the "Super Safety" product embodies this technology, specifically accusing it of being a dual-mode cam selector that allows for selection between safe, active reset, and passive reset modes Compl. ¶77 Compl. p. 53

U.S. Patent No. 12,578,159 - Firearm Trigger Mechanism

  • Issued: March 17, 2026
  • Technology Synopsis: This patent discloses a firearm trigger mechanism that can be selected to operate in either a standard semi-automatic mode or a "forced reset semi-automatic mode" Compl. ¶64 The mechanism uses a cam that is rotated by the cycling of the firearm's bolt to force the trigger member to reset, preventing the trigger from being pulled again until the action is in battery Compl. ¶24
  • Asserted Claims: Independent claim 1 Compl. ¶89
  • Accused Features: The complaint accuses both the "Super Safety" and "Kabuto" products of infringing by allegedly incorporating a mechanism that operates in both a standard semi-automatic and a forced reset semi-automatic mode Compl. ¶¶89; Compl. ¶91-92

U.S. Patent No. 12,636,403 - Firearm Trigger Mechanism

  • Issued: May 26, 2026
  • Technology Synopsis: The patent describes a trigger device with the ability to be selected to operate in two distinct modes: a "standard disconnector semiautomatic mode" and a "forced reset semiautomatic mode" Compl. ¶27 The selection is made via a safety selector '403 Patent, abstract
  • Asserted Claims: Independent claims 38 and 54 Compl. ¶104
  • Accused Features: The "Super Safety" and "Kabuto" are alleged to infringe by having a safety selector that allows the user to move between a standard semi-automatic position and a forced reset semi-automatic position Compl. ¶¶106-108

III. The Accused Instrumentality

Product Identification

The accused instrumentalities are the "Super Safety" and "Kabuto" trigger systems Compl. ¶¶29-37

Functionality and Market Context

  • The complaint alleges that Defendants market and sell the "Super Safety" and "Kabuto" as upgrade kits for AR-pattern firearms Compl. ¶¶30-31 Compl. ¶34-35
  • The accused products are described as "active trigger system[s]" that "actively reset," allowing for faster follow-up shots Compl. p. 14 Compl. p. 15 Marketing materials cited in the complaint promote the products using the designation "FRT," which Plaintiffs claim is their trademark for "Forced Reset Trigger" Compl. ¶¶17 Compl. ¶40
  • The complaint alleges these kits include, at a minimum, cam and lever components, which, when installed with a standard AR-pattern hammer and disconnector, create the allegedly infringing trigger mechanisms (Compl. ¶31; Compl. ¶35). The complaint provides a screenshot of the "Tim Hoffman Super Safety" product page, which describes it as having a "quick reset" Compl. p. 7

IV. Analysis of Infringement Allegations

'247 Patent Infringement Allegations

Claim Element (from Independent Claim 15) Alleged Infringing Functionality Complaint Citation Patent Citation
A firearm trigger mechanism comprising: a hammer ... a trigger member ... a disconnector ... a cam ... and a safety selector... The Super Safety and Kabuto are alleged to be trigger mechanisms that, when installed, comprise these components. ¶47; ¶48 col. 2:21-36
whereupon in a standard semi-automatic mode, ... rearward movement of the bolt carrier causes rearward pivoting of said hammer such that said disconnector hook catches said hammer hook, In standard mode, the rearward movement of the bolt carrier is alleged to cause the hammer (red) to pivot rearward, where it is caught by the disconnector hook (orange). ¶47 col. 3:49-54
at which time a user must manually release said trigger member to free said hammer from said disconnector to permit said hammer and trigger member to pivot to said set positions so that the user can pull said trigger member to fire the firearm, The complaint alleges that the user must manually release the trigger (brown) to free the hammer (red) from the disconnector (orange), allowing the system to reset. A plaintiff-generated diagram illustrates this required user action. (Compl. p. 23). ¶47 col. 3:55-61
and whereupon in a forced reset semi-automatic mode, ... rearward movement of the bolt carrier causes rearward pivoting of said hammer such that said disconnector hook is prevented from catching said hammer hook, In forced reset mode, the cam is allegedly in a second position. Rearward movement of the bolt carrier pivots the hammer (red), but the disconnector hook (orange) is prevented from catching the hammer hook. ¶47 col. 4:1-10
and thereafter the bolt carrier moves forward into battery, at which time the user can pull said trigger member to fire the firearm. After the bolt carrier moves forward, the user can allegedly pull the trigger member (brown) to fire the firearm without first having to release it. ¶47 col. 4:11-14
  • Identified Points of Contention:
    • Scope Questions: Claim 15 requires two distinct and complete operational modes ("standard" and "forced reset"). A central question will be whether the accused products, as sold and installed, are in fact "operable" in both modes as claimed.
    • Technical Questions: The claim requires that in forced reset mode, the disconnector hook is "prevented from catching said hammer hook." The mechanism by which this prevention occurs in the accused products will be a key factual issue. The complaint's diagrams show the cam interacting with the trigger and selector, but the precise interaction that "prevents" the disconnector catch will be subject to scrutiny.

'784 Patent Infringement Allegations

Claim Element (from Independent Claim 1) Alleged Infringing Functionality Complaint Citation Patent Citation
...an extended trigger member locking device, comprising: a locking member that is movable between a first position in which it locks a trigger against pulling movement and a second position where it does not restrict movement... The Super Safety is alleged to operate as a locking member with a first "Locked" position and a second "Unlocked" position. A plaintiff-generated rendering depicts the Super Safety in both positions. (Compl. p. 39). ¶62 col. 1:53-58
the locking member having a body portion that is movably supported and an upwardly extending deflectable portion... The Super Safety is alleged to have a body portion supported by the lower receiver and an upwardly extending "deflectable portion (lever arm)." ¶62 col. 2:1-4
...that is separately movable relative to the body portion between an extended position and a deflected position. The complaint alleges the Super Safety's lever arm has a "dovetail connection" designed to allow separate movement relative to the body portion between an extended and a deflected position. A diagram illustrates this alleged separate travel. Compl. p. 42 ¶62 col. 2:4-7
  • Identified Points of Contention:
    • Scope Questions: The claim requires a "deflectable portion that is separately movable." The dispute may center on whether the alleged "dovetail connection" in the Super Safety Compl. p. 41 and the multi-part construction of the Kabuto meet this limitation. A court will have to determine if this language covers a two-piece component with designed play, or if it requires a single, flexible component.
    • Technical Questions: The complaint includes a quote from a "Super Safety Guide" stating, "The dovetail joint does not immediately transfer torque from the lever to the cam. The lever pivots in the cam until the void is filled" Compl. p. 42 This statement raises the question of whether this "pivoting in a void" is functionally equivalent to the claimed "deflected position" of a "deflectable portion."

V. Key Claim Terms for Construction

  • Term ('247 Patent, Claim 15): "forces said trigger member towards said set position"

    • Context and Importance: This term is the functional core of the "forced reset" concept. The infringement analysis will depend on whether the accused devices' action on the trigger constitutes "forcing" it to the "set position," as opposed to merely biasing it or partially resetting it.
    • Intrinsic Evidence for Interpretation:
      • Evidence for a Broader Interpretation: The general description in the summary of the invention states the cam lobe "forces the trigger member to the set position" without specifying the degree or completeness of the force, which may support an interpretation that any mechanical action pushing the trigger toward reset meets the limitation '247 Patent, col. 2:60-62
      • Evidence for a Narrower Interpretation: The detailed description of the operation explains that the cam's action "forces the hammer and trigger member to their set positions wherein the sear engages the sear catch" '247 Patent, col. 9:52-55 This language suggests that "forces" implies a complete action that results in the full re-engagement of the sear, potentially leading to a narrower construction.
  • Term ('784 Patent, Claim 1): "upwardly extending deflectable portion that is separately movable"

    • Context and Importance: This term defines the central novel feature alleged to solve the problem of adapting a forced reset trigger to different firearm geometries. Practitioners may focus on this term because the infringement allegation against the Super Safety relies on its "dovetail connection" Compl. p. 41, which may or may not be considered "deflectable" and "separately movable" in the context of the patent.
    • Intrinsic Evidence for Interpretation:
      • Evidence for a Broader Interpretation: The patent's claims use the general terms "deflectable" and "separately movable," which could be argued to encompass any two-piece design with relative motion, including the alleged dovetail joint of the accused product. The summary of the invention states the invention "provides a deflectable extension... that is actuated by forward movement of the bolt carrier, but deflects or folds to avoid interfering" '784 Patent, col. 1:45-49, using broad functional language.
      • Evidence for a Narrower Interpretation: The specification explicitly illustrates an alternative embodiment with a "hinging movement" where an extension "is pivotable in one direction" on a pivot pin '784 Patent, col. 4:38-44 '784 Patent, figs. 8-10 A defendant may argue that "deflectable" and "separately movable" should be construed in light of this more specific hinged embodiment, potentially narrowing the claim scope to exclude a sliding or pivoting-within-a-void mechanism.

VI. Other Allegations

  • Indirect Infringement: The complaint alleges both induced and contributory infringement. Inducement is based on allegations that Defendants encourage and instruct customers on how to install and use the accused products to infringe Compl. ¶49 Compl. ¶64 Contributory infringement is based on allegations that the components of the Super Safety and Kabuto are "specially designed and adapted" for use in an infringing manner and are "not suitable for substantial noninfringing use" Compl. ¶51 Compl. ¶66
  • Willful Infringement: The complaint alleges that Defendants "have known or should have known" that their actions constituted infringement and that they "could not reasonably or subjectively believe that their actions do not constitute infringement" or that the patents are invalid Compl. ¶52 Compl. ¶67 This is asserted as the basis for willful infringement.

VII. Analyst's Conclusion: Key Questions for the Case

  • A core issue will be one of definitional scope: can the term "separately movable... deflectable portion" from the '784 Patent, which is described in the context of a hinged or folding extension, be construed to cover the accused products' alleged "dovetail joint" and multi-part constructions?
  • A key evidentiary question will be one of operational equivalence: do the accused "Super Safety" and "Kabuto" devices perform the specific, multi-step sequence of functions required by claim 15 of the '247 Patent, particularly regarding the allegation that a safety selector "prevents" the disconnector from catching the hammer in forced reset mode, or is there a fundamental mismatch in their method of operation?
  • A central validity question for the court will likely be one of obviousness: given the prior art in forced reset triggers cited in the patents themselves, are the specific multi-mode selection mechanisms and adaptable locking members claimed in the patents-in-suit non-obvious improvements, or are they obvious combinations of known elements to a person skilled in firearm mechanism design?
