Patent 9667751

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 patent remains with Realtime Data LLC, the original assignee and apparent operating company.
  2. Known asserter in the chain — not present. Realtime Data LLC is not a publicly known NPE.
  3. Repeat correspondent across the chain — not present. Only one assignment record is available.
  4. Cascading transfers — not present. Only one assignment record is available.
  5. Pre-litigation transfer — unclear. While the patent family has litigation, the assignment (2017-04-10) occurred before the earliest listed litigation filing (2017-08-04, for case 2:17-cv-07690 in California Central District Court). However, without knowing the exact date the decision to litigate was made, it's difficult to definitively classify as "pre-litigation transfer."
  6. Bankruptcy fire-sale — not present. No indication of bankruptcy for Realtime Data LLC.
  7. Privateering — not present. No evidence found of an operating company transferring to an NPE for assertion.
  8. Defensive aggregator (anti-NPE) — not present. The patent is not assigned to a defensive aggregator.

Verdict

Insufficient data. While the patent is involved in litigation, the provided assignment records only show the assignment from the inventors to the original assignee, Realtime Data LLC (Reel 039474/0971, recorded 2017-04-10). There are no subsequent assignments recorded to indicate a transfer to a shell entity or a known NPE. Therefore, there is not enough information to confidently classify this patent as an NPE assertion.
