Title: Trigger mechanism
Patent number: US 9,146,067 B2
Application number: US 13/919,085
Inventor: Michael A. Stakes
Original assignee: Individual (listed as such at filing). The record also lists "Tac-Con Distribution, LLC," "Dark Flame Innovations LLC," and "Abc Ip Inc" as assignees/current assignees, with "Rare Breed Triggers, Inc." shown under a license entry dated 2026-04-14.
Key dates: Priority date and filing date 2013-06-17; publication of US 20140366418 A1 on 2014-12-18; patent granted/publication 2015-09-29. Legal status is listed as "Active - Reinstated," with an adjusted expiration of 2034-03-26. PCT priority to PCT/US2014/011430 is noted.
Purpose / plain-language scope: The subject matter is a trigger mechanism. The excerpt's "prior art keywords" — trigger, hammer, disconnector, reset lever, nose — indicate the mechanism involves a hammer, a disconnector, and a reset lever acting on a nose feature. No abstract, summary, or claim text appears in the supplied excerpt, so the exact claimed structure, the field of use, and the specific operation cannot be described from this source alone.
Family/related filings referenced in the record: US 20140366418 A1, WO 2014204520 A1, US 14/700,074 (US 9267751 B2), and US 14/867,334 (US 9518793 B1).

What the excerpt does not establish: The full text of any claim, the abstract, a detailed description, or any drawing content is absent, so the invention's precise scope and operation cannot be verified from the supplied material. No prior-art references are identified. The listed assignees are expressly stated by the source to be unverified, and the legal-status and priority-date entries are labeled assumptions rather than legal conclusions. Litigation, ownership transfers, and validity are not analyzed here.

Assignment history
Inventors, original assignee, and the chain of ownership recorded with the USPTO — including the correspondent attorney who recorded each assignment, since shell-LLC chains often share one repeat-player attorney even when the entity names look unrelated. Surfaces NPE / patent-troll patterns: shell-entity transfers, known asserters in the chain, repeat correspondent fingerprints, pre-litigation assignments, and bankruptcy fire-sales.
Prior art
Earlier patents, publications, and products that may anticipate or render the claims unpatentable.
Obviousness
Combinations of prior art that suggest the claimed invention would have been obvious under 35 U.S.C. § 103.
Extensions
Patent term adjustments, term extensions, continuations, divisionals, family members, and expiration dates.
Derivative works
Defensive disclosure: derivative variations of each claim designed to render future incremental improvements obvious or non-novel.
