NPE / troll-pattern signals

  1. Shell-entity transfer — not present. The patent was assigned directly from the inventor to Bulletproof Property Management LLC. There is no transfer from an operating company to a shell entity in the provided records.

  2. Known asserter in the chain — not present. Bulletproof Property Management LLC does not appear on public NPE lists from the provided context.

  3. Repeat correspondent across the chain — not present. There is only one assignment recorded, and no specific correspondent information is provided beyond the assignee name itself.

  4. Cascading transfers — not present. Only one assignment is recorded.

  5. Pre-litigation transfer — unclear. While the Google Patents record indicates "Family has litigation" and specifies a "US case filed in Texas Western District Court" on 1:25-cv-00665 and a "PTAB case IPR2026-00204 filed (Pending)", the exact filing dates of these cases relative to the assignment date (October 27, 2024) are not precise enough to confirm a pre-litigation transfer within a 6-month window without further investigation into the complaint filing date. The Google Patents information states the PTAB case IPR2026-00204 is "filed (Pending)" and the US case in Texas Western District Court is listed as "1:25-cv-00665" which implies a 2025 filing year.

  6. Bankruptcy fire-sale — not present. No indication of bankruptcy for the assignor or assignee.

  7. Privateering — not present. No evidence of an operating company transferring to an NPE to assert on its behalf.

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

Verdict

Insufficient data. The only recorded assignment is from the inventor to Bulletproof Property Management LLC. Without information on Bulletproof Property Management LLC's business activities or further assignment records, it is not possible to confidently determine if this entity is an NPE or an operating company. While there is litigation associated with the patent family, the current assignment record does not provide sufficient information to establish an NPE pattern.
