Patent 11031677

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. The only recorded assignment is from the inventors back to Fractus SA, an operating company.
  2. Known asserter in the chain — Not present. Fractus SA is an operating company.
  3. Repeat correspondent across the chain — Not present. There is only one assignment record for this patent in the USPTO assignment database, so recurrence cannot be observed in this chain.
  4. Cascading transfers — Not present. Only one assignment is recorded.
  5. Pre-litigation transfer — Unclear. While Google Patents indicates litigation, the single assignment in the USPTO assignment record (2023-06-27) is not within 6 months of the original filing date (2020-03-27) or issue date (2021-06-08). However, the priority date of the earliest related litigation (Unified Patents case filed 2024-07-24, District Court case filed 2024-07-24) is more than 6 months after the assignment.
  6. Bankruptcy fire-sale — Not present. No evidence of bankruptcy.
  7. Privateering — Not present. No evidence of privateering.
  8. Defensive aggregator (anti-NPE) — Not present. The patent remains with Fractus SA.

Verdict

Insufficient data. The single assignment recorded on reel 055928/0879 is a reassignment from the inventors to the original assignee, Fractus S.A. This does not provide sufficient information to identify an NPE or operating company assertion pattern, other than Fractus S.A. is actively managing its patent ownership. The Google Patents information indicates litigation, but the assignment records do not show a transfer to a known NPE.
