I. Executive Summary and Procedural Information

  • Parties & Counsel:
  • Case Identification: 1:25-cv-00389, E.D. Tenn., 02/16/2026
  • Venue Allegations: Venue is alleged to be proper as Defendants reside in the district and/or have a regular and established place of business there.
  • Core Dispute: Plaintiffs allege that Defendants’ "Super Safety" firearm trigger systems, distributed as downloadable 3D-printable designs, infringe four patents related to forced reset trigger mechanisms.
  • Technical Context: The technology at issue involves forced reset triggers for semi-automatic firearms, which utilize the energy from the firing cycle to mechanically reset the trigger, potentially enabling a higher rate of fire than conventional trigger mechanisms.
  • Key Procedural History: The complaint details a prior dispute between the parties over a related patent (U.S. Patent No. 10,514,223), which resulted in a February 2022 settlement agreement. Plaintiffs allege that during these prior negotiations, Defendants were explicitly warned about Plaintiffs' broader patent portfolio. The complaint also notes that U.S. Patent No. 7,398,723 expired in September 2024, limiting infringement claims for that patent to past damages. A preliminary injunction was entered against the Defendants on February 11, 2026, just prior to the filing of this amended complaint.

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 background discusses the desire among some firearm users to increase the rate of semi-automatic fire and references prior art devices designed to achieve this, implying a need for an improved, more versatile mechanism (’247 Patent, col. 1:15-2:14).
  • The Patented Solution: The invention is a trigger mechanism featuring a three-position selector that allows the user to choose between "safe," "standard semi-automatic," and "forced reset semi-automatic" modes (’247 Patent, abstract). In the forced reset mode, the cycling of the firearm's bolt carrier actuates a cam that mechanically forces the trigger to its reset position, enabling rapid subsequent shots (’247 Patent, col. 2:15-3:10). In the standard semi-automatic mode, a disconnector functions conventionally, catching the hammer after a shot and requiring the user to manually release the trigger to reset it (’247 Patent, col. 2:55-3:4).
  • Technical Importance: The invention provides a single, "drop-in" trigger module that offers the user the flexibility of both a conventional semi-automatic trigger pull and an accelerated, forced-reset firing mode (Compl. ¶37).

Key Claims at a Glance

  • The complaint asserts independent Claim 15 (Compl. ¶65).
  • Essential elements of Claim 15 include:
    • A firearm trigger mechanism comprising a hammer, a trigger member, a disconnector, and a cam.
    • A "standard semi-automatic mode" wherein the cam is in a first position, and rearward movement of the bolt carrier causes the disconnector hook to catch the hammer hook, requiring a manual release of the trigger to fire again.
    • A "forced reset semi-automatic mode" wherein the cam is in a second position, and rearward movement of the bolt carrier causes the disconnector hook to be prevented from catching the hammer hook, allowing the user to fire again without a manual release.

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

  • Issued: July 9, 2024

The Invention Explained

  • Problem Addressed: The patent describes how forced reset trigger mechanisms are often designed for a specific firearm platform, such as the AR15 (’784 Patent, col. 1:15-20). Due to dimensional differences in other platforms like the AR10, a locking member tall enough to be actuated by the bolt carrier would then interfere with another part of that same carrier as it cycles rearward, rendering the device inoperable (’784 Patent, col. 1:36-44).
  • The Patented Solution: The patent discloses 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 component is rigid in one direction, allowing the bolt carrier's forward movement to actuate it and release the trigger, but it is designed to "give way (i.e., deflect or fold)" when contacted by the cycling bolt carrier from the opposite direction, thus avoiding interference (’784 Patent, col. 2:2-4; ’784 Patent, Fig. 7).
  • Technical Importance: This design allows a single forced reset trigger architecture to be adapted for use across multiple firearm platforms with varying internal geometries, broadening its market applicability (Compl. ¶43).

Key Claims at a Glance

  • The complaint asserts independent Claim 1 and dependent Claim 4 (Compl. ¶75; Compl. ¶78).
  • Essential elements of independent Claim 1 include:
    • An extended trigger member locking device for a forced reset trigger mechanism.
    • A locking member movable between a first position (locking the trigger) and a second position (not restricting the trigger).
    • The locking member has a movably supported body portion.
    • The locking member also has an "upwardly extending deflectable portion that is separately movable" relative to the body portion, capable of moving between an extended and a deflected position.

U.S. Patent No. 7,398,723 - Trigger Forward Displacement System and Method

  • Issued: July 15, 2008
  • Technology Synopsis: This patent addresses increasing the cyclic rate of a semi-automatic firearm (Compl. ¶36). The patented solution is a method where depressing the trigger activates a reciprocating mechanism (like a bolt carrier), which in turn causes a cam to rotate, pushing the trigger forward into a ready-to-fire position and holding it there until the firearm's action has closed (Compl. ¶42; ’723 Patent, abstract).
  • Asserted Claims: Claim 1 (Compl. ¶87).
  • Accused Features: The complaint alleges that the "Super Safety" device, when used as instructed, performs the patented method of using a cam actuated by the bolt carrier to forcibly reset the trigger (Compl. ¶90).

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

  • Issued: January 26, 2026
  • Technology Synopsis: The patent discloses a safety mechanism providing three selectable modes of operation: safe, standard semi-automatic (passive reset), and forced reset (active reset) (Compl. ¶46). The invention centers on a "cam selector" with a longitudinal slot for a lever and two distinct recesses on its bottom side that interact with a "first trigger tail portion" to enable the different functions (’538 Patent, abstract).
  • Asserted Claims: Claim 1 (Compl. ¶159).
  • Accused Features: The "Super Safety" is accused of being a multi-mode safety mechanism that includes a cam selector with recesses and a trigger with a tail portion that operate together to provide safe, passive reset, and active reset modes, embodying the technology claimed in the patent (Compl. ¶¶47, 161).

III. The Accused Instrumentality

Product Identification

  • The accused products are the "Super Safety" devices and designs, including versions for AR-15 and LR-308 pattern firearms (Compl. ¶21; Compl. ¶49; Compl. ¶¶28, 47).

Functionality and Market Context

  • The "Super Safety" is described as a 3D-printable "active trigger system" that replaces the standard safety selector on an AR-15 style firearm (Compl. ¶49, p.14 screenshot). It allegedly provides the user with the ability to switch between a safe position, a standard semi-automatic mode (referred to as "disconnector mode"), and a forced reset semi-automatic mode (Compl. ¶¶53-54). The complaint alleges that Defendants distribute the designs for these devices as free downloadable files (e.g., 3D print, STEP, and SolidWorks files) via websites, and that Defendants have also sold and imported physical versions (Compl. ¶¶49, 50, 66). The complaint includes a screenshot from a YouTube video titled "Introducing the Super Safety," which premiered on July 21, 2023, as evidence of the product's launch (Compl. ¶88, p. 39).

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 having a sear catch and a hook...a trigger member having a sear...said disconnector having a hook...and a cam having a cam lobe... The Super Safety is installed with a standard hammer, trigger, and disconnector, and the Super Safety itself functions as the claimed cam. ¶67, pp. 19-24 col. 7:45-8:6
whereupon in a standard semi-automatic mode, said cam is in said first position, In standard mode, the Super Safety cam is in its first position. ¶67, p. 25 col. 8:36-39
rearward movement of the bolt carrier causes rearward pivoting of said hammer such that said disconnector hook catches said hammer hook, Rearward bolt carrier movement causes the hammer to pivot and be caught by the disconnector hook. ¶67, p. 25 col. 8:40-44
at which time a user must manually release said trigger member to free said hammer from said disconnector...so that the user can pull said trigger member to fire the firearm, The user must manually release the trigger to free the hammer from the disconnector before the firearm can be fired again. ¶67, p. 26 col. 8:44-50
whereupon in a forced reset semi-automatic mode, Said cam is in said second position, In forced reset mode, the Super Safety cam is in its second position. ¶67, p. 27 col. 8:51-57
rearward movement of the bolt carrier causes rearward pivoting of said hammer such that said disconnector hook is prevented from catching said hammer hook, Rearward bolt carrier movement pivots the hammer, but the Super Safety cam prevents the disconnector hook from engaging the hammer hook. The complaint includes a plaintiff-generated rendering illustrating the relative positions of the parts in the forced reset mode (Compl. ¶67, p. 27). ¶67, p. 27 col. 8:58-62
at which time the user can pull said trigger member to fire the firearm. After the trigger is forcibly reset by the cam, the user can immediately pull the trigger again to fire. ¶67, p. 28 col. 8:62-65
  • Identified Points of Contention:
    • Technical Question: The complaint's infringement theory relies heavily on its own color-coded diagrams to illustrate the internal mechanics (Compl. ¶67, p. 20). A central question for the court will be whether these renderings accurately depict the actual physical operation of the accused "Super Safety" when installed, and whether that operation meets every claim limitation.
    • Scope Question: The claim requires that in the forced reset mode, the disconnector hook is "prevented from catching said hammer hook." The precise mechanism by which this "prevention" occurs in the accused device will be a key factual issue. The analysis will focus on whether the accused device's method of disabling the disconnector falls within the scope of the claim as interpreted in light of the patent's specification.

’784 Patent Infringement Allegations

Claim Element (from Independent Claim 1) Alleged Infringing Functionality Complaint Citation Patent Citation
In a forced rest trigger mechanism, an extended trigger member locking device, comprising: The Super Safety is alleged to be an extended trigger member locking device for use in a forced reset trigger mechanism. ¶77, p. 31 col. 5:11-14
a locking member that is movable between a first position in which it locks a trigger...and a second position where it does not restrict movement of the trigger... The Super Safety operates as a locking member, moving between a first "Locked" position and a second "Unlocked" position. ¶77, p. 32 col. 5:15-19
the locking member configured to be movably supported by a frame and including a generally upward extension portion configured to make actuating contact with a surface of a bolt carrier, The Super Safety is pivotally supported by the firearm's lower receiver (frame) and has an upward extending lever arm that contacts the bolt carrier. ¶77, p. 33 col. 5:20-25
the locking member having a body portion that is movably supported, The Super Safety has a body portion that is movably supported by the lower receiver. ¶77, p. 34 col. 5:28-29
and an upwardly extending deflectable portion that is separately movable relative to the body portion between an extended position and a deflected position. The Super Safety has an upwardly extending lever arm (deflectable portion) connected to its body via a "dovetail joint," which is alleged to allow separate movement relative to the body portion. The complaint provides a visual overlay to illustrate this separate travel (Compl. ¶77, p. 35). ¶77, pp. 34-36 col. 5:30-34
  • Identified Points of Contention:
    • Scope Question: A core legal and technical question will be whether the accused device's "dovetail joint" connection meets the claim limitation of a "deflectable portion that is separately movable." The analysis may turn on whether "deflectable" can be construed to cover the pivoting motion within a joint, as alleged, or if it is limited to the elastic bending of a material or movement about a more traditional hinge as depicted in the patent's figures.
    • Technical Question: The complaint quotes a "Super Safety Guide" stating that the "dovetail joint does not immediately transfer torque" and allows the lever to pivot until a void is filled (Compl. ¶77, p. 36). The functional significance of this described operation will be scrutinized to determine if it is technically equivalent to the "deflecting" or "folding" action described in the patent to avoid bolt carrier interference.

V. Key Claim Terms for Construction

For the ’247 Patent:

  • The Term: "prevented from catching" (from Claim 15)
  • Context and Importance: This phrase defines the key operational difference between the standard and forced reset modes. The infringement analysis will depend on whether the accused device's mechanism for disabling the disconnector falls within the scope of this term. Practitioners may focus on this term because it is functional language whose boundaries will be debated.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The claim language itself is broad, not specifying how the prevention must occur. The specification states that a "narrow semi-circular portion 116 permits the trigger blade 54 to be pulled but prevents the disconnector 60 from pivoting" ('247 Patent, col. 8:55-60), which could be interpreted as one example of a broader principle of prevention.
    • Evidence for a Narrower Interpretation: The specific embodiment in the patent illustrates this prevention via direct physical obstruction by a portion of the safety selector (’247 Patent, Fig. 6A-6B). A defendant may argue that the term should be limited to this disclosed mechanism of direct physical blocking.

For the ’784 Patent:

  • The Term: "upwardly extending deflectable portion that is separately movable" (from Claim 1)
  • Context and Importance: This term captures the core innovation for adapting the device to different firearm platforms. The case may turn on whether the accused device's dovetail joint meets this definition.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The summary of the invention describes the goal as providing a "deflectable extension" that "deflects or folds" to avoid interference ('784 Patent, col. 2:50-54). The specification also uses the phrase "give way (i.e., deflect or fold)" when describing the function, suggesting the term could encompass multiple types of non-rigid movement, including pivoting within a joint (’784 Patent, col. 2:2-3).
    • Evidence for a Narrower Interpretation: The detailed description and figures primarily show an extension that pivots on a distinct transverse pin (’784 Patent, Fig. 2-4; ’784 Patent, col. 3:40-44). A defendant could argue the term should be limited to a component that either elastically bends or pivots on a dedicated hinge, not one that merely exhibits rotational play within a keyed joint.

VI. Other Allegations

  • Indirect Infringement: The complaint alleges both induced and contributory infringement. Inducement is based on Defendants providing downloadable 3D printer files, development packs, and instructions that allegedly direct users to assemble and use the "Super Safety" in an infringing manner (Compl. ¶52; Compl. ¶69; Compl. ¶81). Contributory infringement is alleged on the basis that the accused devices are a material part of the inventions, are especially made for an infringing use, and are not staple articles of commerce (Compl. ¶66; Compl. ¶76).
  • Willful Infringement: The complaint makes extensive allegations to support willfulness. It points to a 2022 settlement agreement over a related patent, during which Defendants were allegedly warned about Plaintiffs' patent portfolio (Compl. ¶¶25-26). It further alleges that Defendant Hoffman made statements about designing "around" the patents, admitted infringement in private conversations, and pursued a deliberate strategy to "overwhelm the market" with infringing designs to make enforcement "difficult, if not impossible" (Compl. ¶26; Compl. ¶29; Compl. ¶32).

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

  • A central issue will be one of definitional scope: can the term "deflectable portion that is separately movable" from the ’784 Patent, which the specification illustrates with distinct hinges and pivots, be construed to cover the alleged "dovetail joint" of the accused device, or does that design represent a non-infringing mechanical alternative?
  • A second key issue will be one of intent: given the extensive history alleged in the complaint—including prior disputes, a settlement agreement, and alleged admissions by the Defendant—the court will have to weigh whether the alleged infringement was not only known but part of a deliberate strategy to undermine Plaintiffs' patent rights, a finding that could support a claim for enhanced damages.
  • A crucial evidentiary question will be one of operational accuracy: will discovery confirm that the plaintiff-generated diagrams used throughout the complaint accurately depict the mechanical interactions within the accused "Super Safety" device, and does that real-world operation satisfy every limitation of the asserted claims, particularly the functional requirement of "preventing" the disconnector as required by the ’247 Patent?
