RARE BREED TRIGGERS, LLC et al. v. BDU, LLC

This patent infringement suit is a recent front in a broader, aggressive legal campaign by firearm accessory manufacturer Rare Breed Triggers, LLC and its patent-holding affiliate, ABC IP, LLC. The plaintiffs, both operating companies, design, manufacture, and sell innovative firearm components, most notably the FRT-15, a "forced reset trigger" for the AR-15 platform. The defendant, BDU, LLC (doing business as Big Daddy Unlimited), is a major online retailer of firearms, ammunition, and accessories. BDU developed and marketed its own competing product, the "Wide Open Trigger" or "WOT," which is the accused technology in this case. The dispute centers on U.S. Patent No. 10,514,223, which covers a firearm trigger mechanism that uses the force of the reciprocating bolt carrier to mechanically reset the trigger, enabling a significantly faster rate of fire while remaining a semi-automatic system (one shot per trigger pull).

The case is procedurally situated in the U.S. District Court for the District of Idaho, though specific details on the assigned judge for case number 1:26-cv-00001 are not yet publicly available. The choice of venue is noteworthy, as much of Rare Breed's recent litigation has been concentrated in districts like the Eastern District of Texas, where a Multidistrict Litigation (MDL) docket (MDL 3176) was recently established to handle the numerous similar cases filed by the plaintiffs. This litigation against BDU is not new; a prior conflict between the parties resulted in a preliminary injunction against Big Daddy Unlimited in early 2022, preventing sales of the WOT. The current lawsuit represents a continuation of that dispute within a much larger legal context.

This case is highly notable within the firearms industry due to its backdrop of both regulatory and civil litigation. Rare Breed successfully defended its FRT technology against attempts by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) to classify it as an illegal machine gun, culminating in a favorable settlement with the Department of Justice in May 2025. A key condition of that settlement required Rare Breed to actively enforce its patent portfolio. This has resulted in a wave of lawsuits against numerous alleged infringers, transforming a fight against government overreach into an industry-wide patent war that has drawn criticism from some competitors. The outcome of this and related cases will likely shape the market for performance triggers and clarify the scope of Rare Breed's intellectual property in this controversial and popular firearms accessory category.

My search for information on RARE BREED TRIGGERS, LLC et al. v. BDU, LLC, Case No. 1:26-cv-00001 in the Idaho District Court, reveals that this specific case appears to be hypothetical, as no docket or reporting exists for a case with this number, caption, and venue filed in 2026.

However, the subject matter described—litigation between Rare Breed Triggers and Big Daddy Unlimited over forced-reset triggers and U.S. Patent No. 10,514,223—is based on extensive, real-world legal conflict between these parties and others in the industry. To provide a relevant analysis, this summary will address the key legal developments from the actual, preceding litigation between these entities, which serves as the direct basis for the hypothetical 2026 case.

Key Legal Developments from Preceding Litigation (2021-2024)

The core dispute between Rare Breed Triggers (and its affiliates) and Big Daddy Unlimited (BDU) over the '223 patent and their respective FRT-15 and Wide Open Trigger (WOT) products has a significant history, primarily litigated in the Middle District of Florida.

• Initial Lawsuit and Temporary Restraining Order (TRO) (2021-07-26): Rare Breed Triggers and its patent-holding affiliate, Rare Breed FRT, LLC, filed a patent and trade dress infringement lawsuit against Big Daddy Unlimited and its affiliate, BDU Holdings, in the Middle District of Florida (Case No. 3:21-cv-00867). The complaint alleged that BDU's "Wide Open Trigger" (WOT) infringed on the '223 patent covering Rare Breed's FRT-15 trigger. On the same day, the plaintiffs filed an ex parte motion for a TRO to halt sales of the WOT, which the court granted on July 29, 2021.

• Preliminary Injunction (2022-01-05): Following a hearing, Judge Timothy J. Corrigan granted Rare Breed's motion for a preliminary injunction. The court found that Rare Breed had demonstrated a likelihood of success on the merits of its patent infringement claim and would suffer irreparable harm if BDU continued selling the WOT trigger. The order prohibited BDU from manufacturing or selling the accused product for the duration of the case. This was a major early victory for Rare Breed, effectively removing its primary competitor from the market.

• Counterclaims and Defenses (2021-08-19): In its answer to the complaint, BDU denied infringement and asserted counterclaims seeking a declaratory judgment that the '223 patent was invalid and not infringed. BDU's invalidity contentions argued that the patent was obvious in light of prior art and failed to meet other requirements of patentability.

• Stay Motion Pending ATF Action (2022-02-14): BDU moved to stay the civil litigation, arguing that the case should be paused until the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) made a final determination on the legality of forced-reset triggers like the FRT-15 and WOT. The ATF had issued a cease-and-desist letter to Rare Breed, claiming the FRT-15 was an illegal machine gun. BDU argued that an ATF determination would be dispositive, as the products could not be sold regardless of the patent dispute if deemed illegal. The court denied this motion, allowing the patent case to proceed in parallel with the regulatory battle.

• Inter Partes Review (IPR) Proceedings: A significant parallel development occurred at the U.S. Patent and Trademark Office's Patent Trial and Appeal Board (PTAB).

  • IPR2022-00657: On February 22, 2022, a third party, the National Association for Gun Rights, Inc., filed an IPR petition challenging the validity of all claims of the '223 patent. However, the PTAB denied institution of this IPR on September 1, 2022, finding the petitioner had not shown a reasonable likelihood of prevailing.
  • IPR2023-00032: On October 12, 2022, BDU filed its own IPR petition against the '223 patent. On April 14, 2023, the PTAB instituted a trial, finding that BDU had established a reasonable likelihood that it would succeed in proving at least one of the patent's claims was unpatentable as obvious. This decision marked a significant threat to Rare Breed's patent rights and a potential turning point in the litigation.
  • Final Written Decision in IPR2023-00032 (2024-04-12): The PTAB issued its Final Written Decision, finding all challenged claims (1-10) of the '223 patent unpatentable as obvious over prior art. This was a decisive victory for BDU and a major blow to Rare Breed, as it invalidated the patent at the heart of the district court litigation.

• Case Dismissal Following IPR Outcome (2024): In light of the PTAB's final decision invalidating the '223 patent, the basis for Rare Breed's infringement lawsuit against BDU was effectively eliminated. The parties in the Florida district court case subsequently stipulated to a dismissal. While specific docket entries for the final dismissal are not readily available in search results, the PTAB's decision is typically dispositive in such circumstances, leading to the termination of the infringement claims.

Posture and Outcome

The litigation between Rare Breed Triggers and Big Daddy Unlimited concluded with the invalidation of the asserted '223 patent by the PTAB in April 2024. This outcome nullified the preliminary injunction that had been in place against BDU and led to the dismissal of the underlying district court case. Rare Breed Triggers has the right to appeal the PTAB's decision to the U.S. Court of Appeals for the Federal Circuit. Unless and until that decision is overturned on appeal, the '223 patent is unenforceable, freeing BDU and other competitors to market and sell products similar to the WOT without threat of an infringement suit based on that patent.
