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 — not present. The patent was assigned directly from the inventors to Cisco Technology Inc., a large operating company.
  2. Known asserter in the chain — not present. Cisco Technology Inc. is an operating company, not a known NPE.
  3. Repeat correspondent across the chain — unclear. The initial assignment record does not list a correspondent. As there is only one assignment, recurrence cannot be determined.
  4. Cascading transfers — not present. Only one assignment is recorded.
  5. Pre-litigation transfer — not present. No litigation information is provided in the assignment record, and no subsequent transfers are listed.
  6. Bankruptcy fire-sale — not present. Cisco Technology Inc. is an active, operating company.
  7. Privateering — not present. The patent remains with the original operating company.
  8. Defensive aggregator (anti-NPE) — not present. The patent is currently held by Cisco Technology Inc.

Verdict

Insufficient data. Only the original assignment from the inventors to Cisco Technology Inc. is recorded. There are no subsequent assignments to analyze for NPE patterns. [cite: "2009-05-26 (executed) / recorded 2009-05-26 — Reel 022731/0565"]
