Litigation summary

As a patent attorney on April 26, 2026, a review of litigation records reveals that US Patent No. 7,398,723 ('723 patent) has been involved in litigation. The patent is currently assigned to ABC IP, LLC, which, along with Rare Breed Triggers, Inc., has been actively asserting its patent portfolio.

A significant portion of the litigation involving ABC IP, LLC and Rare Breed Triggers has been centralized into a multidistrict litigation (MDL) proceeding to streamline discovery and pretrial motions.

Known Litigation Involving US Patent No. 7,398,723:

1. ABC IP, LLC et al v. Hoffman et al

• Plaintiffs: ABC IP, LLC and Rare Breed Triggers, Inc.
• Defendants: Timothy Hoffman and Hoffman Tactical, LLC
• Jurisdiction: U.S. District Court for the Eastern District of Tennessee
• Case Number: 1:25-cv-00389
• Filing Date: December 22, 2025
• Status/Outcome: As of February 2026, the case is active. The court granted a preliminary injunction in favor of the plaintiffs on February 11, 2026. An amended complaint was filed by the plaintiffs on February 16, 2026, which includes allegations of infringement of the '723 patent. The complaint notes that claims related to the '723 patent, which expired in September 2024, are for past damages.

Multidistrict Litigation (MDL No. 3176):

Numerous patent infringement cases filed by ABC IP, LLC and Rare Breed Triggers, Inc. against various defendants have been centralized into an MDL docket titled In re: Rare Breed Triggers Patent Litigation. This was done to consolidate the management of cases involving common questions of fact related to patents for "forced reset triggers" (FRTs). The cases were transferred to the U.S. District Court for the Eastern District of Texas.

While the initial order for centralization focused on several patents, cases involving a range of accused products and asserted patents from the plaintiffs' portfolio are being managed under this MDL. It is likely that other cases asserting the '723 patent are included or will be transferred into this MDL.

For example, cases such as ABC IP, LLC et al. v. 80Mills LLC et al. (originally filed in the Northern District of Ohio) and ABC IP, LLC et al v. Harrison Gunworks LLC et al. (originally from the District of Idaho) have been transferred into this MDL. These cases involve plaintiffs ABC IP, LLC and Rare Breed Triggers, Inc. suing various entities for patent infringement related to their trigger mechanisms.
