Patent 11650968

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 initial assignment is from the inventors to Comet ML, Inc., which is an operating company.

  2. Known asserter in the chain — not present. Comet ML, Inc. is not a known NPE.

  3. Repeat correspondent across the chain — not present. Only one assignment is recorded, so no recurrence can be observed.

  4. Cascading transfers — not present. Only one assignment is recorded.

  5. Pre-litigation transfer — unclear. While the patent family has litigation (IPR2025-01063 was filed), there is only one recorded assignment which occurred before the patent issued and long before the reported litigation. Therefore, there's no evidence of a pre-litigation transfer in the assignment records themselves.

  6. Bankruptcy fire-sale — not present. There is no indication that Comet ML, Inc. has filed for bankruptcy.

  7. Privateering — not present. No evidence of transfer to an NPE for assertion on behalf of an operating company.

  8. Defensive aggregator (anti-NPE) — not present. The patent is owned by an operating company, not a defensive aggregator.

Verdict

Insufficient data. Only one assignment from the inventors to the original assignee is recorded in the USPTO Assignment Center (reel 056461/0815). While Google Patents mentions an IPR case (IPR2025-01063), the USPTO assignment records do not show any subsequent transfers to an NPE or any other entity that would indicate a change in ownership for assertion purposes.
