Patent 11539663

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 — Unclear.

    • Fractal Industries Inc. and QOMPLX Inc. both appear to be operating companies with products and services in cybersecurity and risk analytics.
    • QPX, LLC's primary business appears to be supply chain solutions and sourcing consulting, which seems unrelated to the patent's subject matter. However, QPX LLC quickly changed its name to QOMPLX LLC, suggesting it may have been an interim entity or part of a corporate restructuring. There is also an unrelated entity called AdvisorShares Q Dynamic Growth ETF with the ticker QPX. RPX Insight also refers to "QOMPLX LLC (f/k/a QPX LLC)" having filed its first litigation, indicating that QPX LLC was indeed a predecessor to the current QOMPLX LLC (the patent owner).

  2. Known asserter in the chain — Not present. None of the assignees (Fractal Industries Inc., QOMPLX Inc., QPX LLC) match known public NPE lists. RPX Insight does note that "QOMPLX LLC (f/k/a QPX LLC) has filed its first litigation" using scooped-up QOMPLX patent assets, suggesting they have recently become an asserter.

  3. Repeat correspondent across the chain — Present.

  4. Cascading transfers — Unclear. While there are multiple transfers, they are separated by several years or are internal name/address changes. The transfer from QOMPLX, INC. to QPX, LLC (2023-08-23, Reel 064674/0408) followed by a corrective assignment (2023-09-20, Reel 064887/0932) and then a name change to QOMPLX LLC (2023-09-27, Reel 065011/0212) occurred within a short timeframe, which could be seen as cascading transfers. However, it seems to be an internal restructuring of the "QOMPLX" entity rather than transfers to unrelated shell entities.

  5. Pre-litigation transfer — Present. The transfer from QOMPLX, INC. to QPX, LLC was executed on 2023-08-23 and recorded on the same date (Reel 064674/0408). RPX Insight states that QOMPLX LLC (f/k/a QPX LLC) filed its first litigation in the Western District of Texas (case 1:25-cv-01383) and the Eastern District of Texas (case 2:25-cv-00913) in 2025. This is more than 6 months after the transfer, therefore this signal is not present for this particular patent, even if it is mentioned that the first litigation was filed in 2025.

  6. Bankruptcy fire-sale — Not present. There is no information suggesting that Qomplx Inc. or Fractal Industries Inc. filed for bankruptcy.

  7. Privateering — Unclear. There is no explicit evidence from the provided records or search results to indicate privateering activity.

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

Verdict

NPE — moderate confidence. While the assignees appear to be operating companies, the rapid sequence of transfer to QPX LLC, a corrective assignment, and then a name change to QOMPLX LLC (the current asserter as noted by RPX) within a month in 2023 (Reel 064674/0408, 064887/0932, 065011/0212) suggests a structured preparation for assertion. Additionally, the recurrence of specific legal correspondents (Thomas J Knox and Anthony D. Duluc) across multiple assignments in the chain is a common characteristic of entities involved in patent assertion. RPX Insight explicitly states that "QOMPLX LLC (f/k/a QPX LLC) has filed its first litigation," indicating their recent shift into an asserting role.
