NPE / troll-pattern signals

  1. Shell-entity transfer — present. The patent was assigned from IPWIRELESS, INC. to INTELLECTUAL VENTURES HOLDING 81 LLC, and then to INTELLECTUAL VENTURES II LLC. Intellectual Ventures II LLC is a known patent assertion entity.
  2. Known asserter in the chain — present. Intellectual Ventures Holding 81 LLC and Intellectual Ventures II LLC are both known patent assertion entities (NPEs).
  3. Repeat correspondent across the chain — not present. The correspondent Ryan K. Ehrler is listed for both assignments on 2024-03-28, but does not recur with other entities or across a longer chain for this patent.
  4. Cascading transfers — present. Two consecutive assignments occurred on the same day, 2024-03-28, from IPWIRELESS, INC. to INTELLECTUAL VENTURES HOLDING 81 LLC, and immediately following to INTELLECTUAL VENTURES II LLC.
  5. Pre-litigation transfer — present. The patent was assigned to Intellectual Ventures II LLC on 2024-03-28. According to Google Patents, district court cases were filed in Texas Western District Court on 2024-03-28 and 2024-03-28.
  6. Bankruptcy fire-sale — unclear. There is no information in the provided patent text or Google Patents regarding a bankruptcy of the original assignee or assignors in the chain.
  7. Privateering — unclear. There is no information in the provided patent text or Google Patents to suggest privateering.
  8. Defensive aggregator (anti-NPE) — not present. The chain ends with Intellectual Ventures II LLC, which is a known NPE, not a defensive aggregator.

Verdict

NPE — high confidence
The presence of a known patent assertion entity (Intellectual Ventures II LLC) as the current assignee, coupled with cascading transfers (two assignments on the same day) and pre-litigation transfers (assignments on the same day as infringement suits were filed) strongly indicates an NPE assertion pattern.
