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 transferpresent.

    • 2018-07-25 (executed) / recorded 2018-07-25 — Reel 044234/0073: Voicebox Technologies Corporation assigned to VB ASSETS, LLC. VB Assets, LLC has a name suffix "Assets" and is a common type of shell entity used in patent assertion. While the initial entity VoiceBox Technologies Corporation was an operating company, the transfer to VB Assets, LLC suggests a shift in focus.
  2. Known asserter in the chainunclear. While VB Assets, LLC is the current assignee and a potential shell entity, it does not directly match the provided list of high-frequency plaintiffs. Further investigation beyond the scope of this request would be needed to confirm if VB Assets, LLC is a known asserter.

  3. Repeat correspondent across the chainpresent.

  4. Cascading transfersnot present. While there are multiple assignments, they are interspersed with security interest filings and releases, and don't represent rapid, consecutive transfers through chained LLCs that are characteristic of cascading transfers.

  5. Pre-litigation transferunclear. The summary mentions "Family has litigation" with US cases filed in Texas Eastern District Court and Delaware District Court in 2025 and 2026, but the exact filing dates of these suits are not provided. The latest assignment to VB Assets, LLC was a corrective assignment in 2020-09-22, and a security interest was granted in 2025-04-08. Without the precise litigation filing dates, it is unclear if any assignments occurred within 6 months prior to the first infringement suit naming this patent.

  6. Bankruptcy fire-salenot present. There is no indication in the assignment records or the patent summary that VoiceBox Technologies Corp or any subsequent assignee underwent a bankruptcy fire-sale.

  7. Privateeringunclear. While Nuance Communications, Inc. (an operating company) was briefly an assignee in 2020-01-22, the patent was subsequently transferred back to VB ASSETS, LLC via a corrective assignment in 2020-09-22. This could potentially indicate a privateering arrangement where VB ASSETS, LLC asserts on behalf of Nuance, but this cannot be confirmed without further external information.

  8. Defensive aggregator (anti-NPE)not present. The chain does not terminate at any known defensive aggregators.

Verdict

NPE — moderate confidence

The transfer to VB Assets, LLC (a likely shell entity based on its name and role in the chain) combined with the recurrence of specific correspondents across multiple assignments in the chain (Reel 043232/0761, Reel 043743/0979, Reel 044234/0073, Reel 048997/0122, Reel 045717/0861, Reel 046039/0753) strongly suggest an NPE pattern. The history also includes multiple security interest grants and releases, which are common in patent monetization strategies.
