Patent 10681103

Assignment history

Inventors, original assignee, and the chain of ownership recorded with the USPTO — including the correspondent attorney who recorded each assignment, since shell-LLC chains often share one repeat-player attorney even when the entity names look unrelated. 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. There is no recorded transfer from an operating company to a licensing-only LLC.
  2. Known asserter in the chain — not present. There are no recorded assignments, so no known asserters are in the chain.
  3. Repeat correspondent across the chain — not present. There are no recorded assignments to show a repeat correspondent.
  4. Cascading transfers — not present. No assignments are recorded.
  5. Pre-litigation transfer — unclear. While there's litigation mentioned in Google Patents, without assignment records, it's impossible to determine if a transfer occurred within 6 months prior to any litigation.
  6. Bankruptcy fire-sale — not present. No evidence of a bankruptcy fire-sale in the assignment records.
  7. Privateering — unclear. Without assignment records and further financial disclosures, it's not possible to determine if privateering has occurred.
  8. Defensive aggregator (anti-NPE) — not present. The patent has not been assigned to a defensive aggregator.

Verdict
