NPE / troll-pattern signals

  1. Shell-entity transfer — not present. The transfer was from Dow AgroSciences LLC to Corteva Agriscience LLC, both operating companies in the agricultural sector. [cite: 059952/0150]

  2. Known asserter in the chain — not present. Corteva Agriscience LLC is an operating company, not identified as a known NPE.

  3. Repeat correspondent across the chain — not present. Only one assignment record is present, so there is no recurrence to observe. [cite: 059952/0150]

  4. Cascading transfers — not present. There is only one recorded assignment. [cite: 059952/0150]

  5. Pre-litigation transfer — unclear. There is no information about the timing of any litigation relative to the assignment date in the provided data, and no direct litigation has been found for this patent number.

  6. Bankruptcy fire-sale — not present. The assignment was a change of name/internal reorganization, not a result of bankruptcy. [cite: 059952/0150]

  7. Privateering — not present. The assignment was an internal reorganization between operating companies. [cite: 059952/0150]

  8. Defensive aggregator (anti-NPE) — not present. The current assignee is Corteva Agriscience LLC, an operating company. [cite: 059952/0150]

Verdict

Insufficient data. Only one assignment record is available, reflecting a change of name/internal reorganization from Dow AgroSciences LLC to Corteva Agriscience LLC (Reel 059952/0150, recorded 2021-11-08). This single event does not provide enough evidence to identify any NPE or patent-troll patterns.
