A review of US Patent 11,346,627 reveals the following details regarding the invention and its legal status.

Title: Forced reset semiautomatic trigger with sliding blocking bar

Assignee: ABC IP, LLC

Inventor: Lawrence DeMonico

Filing Date: February 8, 2022

Issue Date: May 31, 2022

Abstract: The patent details a trigger mechanism for a firearm equipped with a reciprocating bolt carrier that displaces a hammer during its cycle. The mechanism includes a hammer and a trigger member, both pivoting on transverse axes. As the bolt carrier cycles, it forces the hammer to contact the trigger member, causing the trigger to reset to its set position. A key innovation is a slideably mounted locking bar, which is spring-biased to mechanically block the trigger from moving. This block is removed only when the bolt carrier returns to its in-battery position, at which point it contacts the locking bar and moves it, allowing the trigger to be operated.

Plain-Language Overview of Independent Claims

US Patent 11,346,627 has two independent claims, which define the core scope of the invention:

Independent Claim 1: This claim outlines the fundamental trigger mechanism. It describes a system where the cycling of the firearm's bolt carrier causes the hammer to pivot, which in turn forcibly resets the trigger. A crucial element is a sliding "locking bar" that is spring-loaded to prevent the trigger from being pulled. Only when the bolt carrier is fully forward (in battery) does it push this locking bar out of the way, permitting the trigger to be pulled and the firearm to be discharged. This ensures that a subsequent shot cannot be fired until the action is properly closed.

Independent Claim 6: This claim is structurally similar to the first, but specifies that the hammer, trigger member, and sliding locking bar are all mounted within a self-contained housing. This describes a "drop-in" trigger module that can be manufactured and installed as a single unit into the fire control mechanism pocket of a firearm receiver, rather than as individual components.

A search of the U.S. Court of Appeals for the Federal Circuit (CAFC) 2026 dockets for cases involving patent 11,346,627 was conducted, and no responsive records were found. This indicates that, as of today's date, there is no public record of appellate litigation concerning this patent in the specified period.
