Here's a concise summary of US patent US11346627:

Patent Number: US11346627
Title: Forced reset semiautomatic trigger with sliding blocking bar
Assignee: ABC IP LLC
Inventors: Lawrence Demonico
Filing Date: 2022-02-08
Issue Date: 2022-05-31
Abstract: Provided is a trigger mechanism for a firearm having a receiver with a fire control mechanism pocket and a bolt carrier that reciprocates to pivotally displace a hammer when cycled. It includes a hammer having a sear notch and mounted in the fire control mechanism pocket to pivot on a transverse axis between set and released positions. A trigger member has a sear and is mounted in the fire control mechanism pocket to pivot on a transverse axis between set and released positions. The trigger member has a first surface positioned to be forcibly contacted by the hammer when the hammer is displaced by cycling of the bolt carrier, the contact causing at least in part the trigger member to be forced to the set position. A locking bar is slideably mounted in a support frame and spring biased toward a first position in which the locking bar mechanically blocks the trigger member from moving to the released position, and is movable against the spring bias to a second position when contacted by the bolt carrier reaching a substantially in-battery position, allowing the trigger member to be moved by an external force to the released position.

Plain-language overview of independent claims:

• Independent Claim 1: This claim describes a trigger mechanism for a firearm with a receiver pocket and a reciprocating bolt carrier that moves a hammer. The mechanism includes a hammer with a sear notch, pivoting on a transverse axis. It also includes a trigger member with a sear, also pivoting on a transverse axis. A key feature is that the trigger member has a surface that the hammer forcibly contacts when the bolt carrier cycles, which helps reset the trigger. The invention introduces a locking bar that slides within a support frame. This locking bar is spring-biased to a "first position" where it prevents the trigger from being pulled. However, when the bolt carrier returns to a fully forward ("in-battery") position, it contacts the locking bar, moving it against its spring bias to a "second position," which then allows the trigger to be pulled to fire the weapon.
• Independent Claim 6: This claim is similar to Claim 1 but specifically describes the trigger mechanism as being contained within a housing. It includes the same elements: a hammer with a sear notch pivoting in the housing, a trigger member with a sear also pivoting in the housing, and the trigger member having a surface contacted by the hammer during bolt carrier cycling to force the trigger to reset. The distinguishing feature here is that the locking bar is slidably mounted in the housing and is spring-biased to block the trigger until the bolt carrier reaches a substantially in-battery position, at which point it is moved to allow the trigger to be pulled.
