ABC IP LLC v. 80Mills LLC — Case Transferred into Rare Breed Triggers MDL
ABC IP LLC filed a patent infringement action against 80Mills LLC in the Northern District of Ohio, asserting two patents covering the 'Super Safety' (3 Position) trigger mechanism. After 301 days, Judge Calabrese ordered the case transferred to the Eastern District of Texas for coordinated pretrial proceedings as part of MDL No. 3176 — now styled In re: Rare Breed Triggers Patent Litigation.
From N.D. Ohio to E.D. Texas: A Trigger Patent Case Enters MDL Consolidation
ABC IP LLC filed this patent infringement action against 80Mills LLC on June 17, 2025 in the United States District Court for the Northern District of Ohio, before Judge J. Philip Calabrese. The suit asserts two patents — US12031784B1 and US12038247B2 — directed to the 'Super Safety' (3 Position) trigger mechanism product. ABC IP LLC was represented by Fish & Richardson LLP and Wood, Herron & Evans, while 80Mills LLC was represented by Emerson Thomson & Bennett LLC.
The recorded basis of termination is 'Case Transferred.' The docket order directs that this action, along with others listed on Schedule A, be transferred to the Eastern District of Texas and, with the consent of that court, assigned to the Honorable Amos L. Mazzant III for coordinated or consolidated pretrial proceedings. The order simultaneously renames the multidistrict litigation MDL No. 3176 as In re: Rare Breed Triggers Patent Litigation.
The transfer to MDL consolidation suggests that ABC IP LLC's trigger mechanism patent assertions span multiple defendants and jurisdictions — a litigation posture consistent with a coordinated enforcement campaign. The merits of the infringement claims and any defenses raised by 80Mills LLC remain unresolved in the public record at this stage; those issues will be addressed through the MDL pretrial process in E.D. Texas.

US12031784B1 & US12038247B2 — 'Super Safety' 3-Position Trigger Mechanism
Any company designing, manufacturing, or distributing multi-position trigger safety mechanisms or aftermarket trigger assemblies should treat US12031784B1 and US12038247B2 as active enforcement risks. ABC IP LLC has demonstrated willingness to assert both patents against multiple defendants concurrently, as evidenced by MDL consolidation. R&D teams developing 3-position or adjustable trigger safety products should conduct FTO analysis before product launch or next manufacturing run.
Official order — verbatim text
The transfer order resolves no merits questions — it is a purely procedural redistribution of the case to a centralised MDL forum. Judge Calabrese's direction that the action join MDL No. 3176, renamed In re: Rare Breed Triggers Patent Litigation and assigned to Judge Mazzant in E.D. Texas, indicates this is one of multiple related infringement actions that the federal MDL panel determined share common questions of fact sufficient to warrant coordination.

Ohio action transferred to the Eastern District of Texas, assigned to Judge Mazzant. The case does not end — it continues as part of MDL No. 3176, now renamed In re: Rare Breed Triggers Patent Litigation. No merits ruling has been issued.

Forward-looking patent intelligence on ABC IP LLC's enforcement portfolio, filing trends in trigger safety technology, and white-space opportunities near US12031784B1 and US12038247B2.
ABC IP LLC's trigger mechanism patent filing activity
ABC IP LLC is asserting at least two issued patents — US12031784B1 and US12038247B2 — in a multi-defendant MDL campaign. Mapping ABC IP LLC's full portfolio and continuation filing activity will reveal whether additional trigger mechanism patents are pending that could extend enforcement reach beyond the current MDL defendants.
Portfolio monitoringFiling trends in 3-position trigger safety mechanisms
The 'Super Safety' 3-position trigger design sits at the intersection of trigger group engineering and safety mechanism innovation. Tracking recent patent filings in this subclass — including multi-position sears, adjustable trigger assemblies, and integrated safety selectors — reveals where competitors are building defensive or offensive IP positions around the ABC IP LLC patents.
Filing trend analysis80Mills LLC and MDL co-defendants: competitive IP landscape
80Mills LLC and the other Schedule A defendants in MDL 3176 likely share overlapping product designs. Analyzing whether any MDL defendants hold their own trigger mechanism patents — or have filed for patent protection — surfaces potential cross-licensing dynamics and indicates which parties have defensive IP assets to deploy in consolidated proceedings.
Competitive IP postureDesign-around space adjacent to US12031784B1 claims
With MDL claim construction pending, the exact boundaries of US12031784B1 and US12038247B2 remain to be defined. Now is the optimal window for R&D teams to identify unclaimed structural variations in trigger safety geometry, material combinations, or actuation sequences that may fall outside the patents' ultimate claim scope — before a binding construction narrows or expands the risk landscape.

ABC v 80Mills — key questions answered
MDL No. 3176, renamed In re: Rare Breed Triggers Patent Litigation by Judge Calabrese's transfer order, is a multidistrict litigation consolidating related patent infringement actions — including ABC IP LLC v. 80Mills LLC — before Judge Amos L. Mazzant III in the Eastern District of Texas for coordinated or consolidated pretrial proceedings.
The complaint asserts two patents: US12031784B1 (underlying application US18/052606) and US12038247B2 (underlying application US18/325225). Both relate to the 'Super Safety' (3 Position) trigger mechanism product. The specific claim language and technical disclosures are not detailed in the available case record.
The case was transferred pursuant to Judge Calabrese's order directing that actions listed on Schedule A — including this N.D. Ohio case — be moved to the Eastern District of Texas for coordinated or consolidated pretrial proceedings as part of MDL 3176. This suggests multiple related infringement actions involving the same patents were filed across different districts.
80Mills LLC's defense continues — the transfer is procedural and does not resolve the merits of the infringement claims or any defenses. The case now proceeds before Judge Mazzant in E.D. Texas alongside other Schedule A defendants. The specific procedural schedule and any rulings on defenses are not disclosed in the available public record at this stage.
Yes. Claim construction rulings issued by Judge Mazzant in MDL 3176 will define the enforceable scope of US12031784B1 and US12038247B2 and will apply across all consolidated defendants. Those rulings could set precedent affecting any company that manufactures, distributes, or sells multi-position trigger safety products in the U.S. market.
