NPE / troll-pattern signals

  1. Shell-entity transfer — Present. The patent was assigned to "Telcom Ventures, LLC" (Reel 047644/0488, executed 2019-01-18 / recorded 2019-01-18). The name "Ventures" is a common suffix for patent licensing entities. Information available through Google Search indicates Telcom Ventures LLC is a patent assertion entity, not a product-shipping company.
  2. Known asserter in the chain — Present. Telcom Ventures LLC is identified by Unified Patents as a patent assertion entity and is actively litigating this patent, as indicated by multiple district court and PTAB cases listed in the Google Patents record (e.g., Texas Eastern District Court case 2:24-cv-00691, California Northern District Court case 5:25-cv-05041, Florida Southern District Court case 1:24-cv-23837, IPR2025-01421, IPR2025-01235, IPR2025-00974).
  3. Repeat correspondent across the chain — Not present. Only one assignment is recorded, so no recurrence can be observed within this specific patent's chain. The correspondent for the initial assignment was David D. Kalish of Patent Law Group (Reel 047644/0488).
  4. Cascading transfers — Not present. Only a single assignment from inventors to the assignee is recorded.
  5. Pre-litigation transfer — Unclear. The assignment from inventors to Telcom Ventures LLC was recorded in 2019-01-18, and the patent issued in 2020-06-02. Litigation against this patent family began in 2024 (e.g., 2:24-cv-00691 in Texas Eastern District Court). This gap of several years between assignment/issuance and litigation does not fit the typical "pre-litigation transfer" pattern of within 6 months.
  6. Bankruptcy fire-sale — Not present. There is no indication of the inventors or Telcom Ventures LLC having undergone bankruptcy proceedings related to this assignment.
  7. Privateering — Unclear. While Telcom Ventures LLC is an NPE, there is no public information readily available to suggest they are asserting this patent on behalf of an operating company against its competitors.
  8. Defensive aggregator (anti-NPE) — Not present. The patent is held by Telcom Ventures LLC, which is an assertion entity, not a defensive aggregator.

Verdict

NPE — high confidence

The verdict is high confidence NPE due to two strong signals: the assignment to "Telcom Ventures, LLC," a known patent assertion entity (Reel 047644/0488, executed 2019-01-18 / recorded 2019-01-18), and the active litigation of this patent by Telcom Ventures LLC in multiple district courts and PTAB proceedings, as noted in the Google Patents record. Telcom Ventures LLC's business model is centered on patent licensing and assertion, not product sales.
