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.

NPE / troll-pattern signals

  1. Shell-entity transfer — Not present. No assignment records are available to indicate a transfer to a shell entity. AX Wireless LLC describes itself as a "Texas based licensing company for Wi-Fi 6 standard-essential and technically necessary patents" that acquires patent portfolios and simplifies licensing. This indicates a business model focused on patent licensing and enforcement, aligning with characteristics of a Non-Practicing Entity (NPE), but without a transfer, the specific "shell-entity transfer" signal is not present.
  2. Known asserter in the chain — Present. The current assignee, AX Wireless LLC, is explicitly identified as a "patent assertion entity (PAE)" and a "non-practicing entity (NPE)" in multiple litigation analyses. Unified Patents also identifies AX Wireless, LLC as an NPE and an entity of IdeaHub.
  3. Repeat correspondent across the chain — Not present. No assignment records are available, so there is no chain to analyze for repeat correspondents.
  4. Cascading transfers — Not present. No assignment records are available.
  5. Pre-litigation transfer — Unclear. While AX Wireless LLC is currently involved in multiple litigations where this patent is asserted, and the patent family has litigation filed as early as February 22, 2025, according to Darts-ip (for other patents in the family) and other litigation databases, and even earlier in February 2023 for a related case, there are no assignment records to show if a transfer occurred within 6 months prior to any of these suits for this specific patent (US11777776). The earliest listed litigation directly involving US11777776 is an ex parte reexamination filed by Unified Patents on February 26, 2026. The patent was granted on October 3, 2023. Without assignment records, it's impossible to confirm a pre-litigation transfer for US11777776.
  6. Bankruptcy fire-sale — Not present. No information suggests the original assignee filed for bankruptcy.
  7. Privateering — Unclear. While AX Wireless LLC is identified as an NPE actively litigating Wi-Fi 6 patents, and has acquired patents from multiple entities, there is no specific evidence within the provided patent text or search results to indicate that an operating company transferred this patent to AX Wireless LLC to assert on its behalf against competitors (privateering).
  8. Defensive aggregator (anti-NPE) — Not present. The patent remains with AX Wireless LLC, an identified NPE, and has not been transferred to a defensive aggregator.

Verdict

NPE — high confidence

AX Wireless LLC, the current assignee, is explicitly identified as a "patent assertion entity (PAE)" and a "non-practicing entity (NPE)" in multiple reliable sources related to litigation involving this patent family. The company's own description of its business model aligns with patent licensing and enforcement. The presence of ongoing and past litigation involving this patent and its family against numerous operating companies further reinforces this verdict.
