Patent 9979826

Assignment history

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 — unclear. The initial assignment is from individuals (the inventors) to Cedarwood Ventures, Inc.. Without further information on Cedarwood Ventures, Inc.'s operations, products, or corporate structure, it's not possible to definitively determine if it's a shell entity.
  2. Known asserter in the chain — not present. Cedarwood Ventures, Inc. is not a commonly listed known NPE.
  3. Repeat correspondent across the chain — unclear. The provided information for the assignment on reel 071457/0512 does not specify a correspondent name or firm.
  4. Cascading transfers — not present. Only one assignment is recorded, from the individual inventors to Cedarwood Ventures, Inc., on 2025-06-19.
  5. Pre-litigation transfer — unclear. The patent family has litigation filed in the Texas Western District Court in 2026. The assignment to Cedarwood Ventures, Inc. was on 2025-06-19. This is within 6 months of the 2026 litigation filing, which could suggest a pre-litigation transfer; however, the exact date of the first suit is not specified, only the year.
  6. Bankruptcy fire-sale — not present. There is no indication of bankruptcy proceedings for the original inventors or Cedarwood Ventures Inc.
  7. Privateering — not present. There is no information to suggest privateering.
  8. Defensive aggregator (anti-NPE) — not present. The patent is not assigned to a defensive aggregator.

Verdict

NPE — moderate confidence

The assignment from individual inventors to Cedarwood Ventures, Inc. occurred on 2025-06-19 (Reel 071457/0512), which is within a year before litigation related to the patent family began in the Texas Western District Court in 2026. This proximity in dates between the assignment and the initiation of litigation suggests a potential pre-litigation transfer to an entity that may be engaged in patent assertion. Further investigation into Cedarwood Ventures, Inc. would be needed to confirm its operating status and business model.
