Patent 11935082

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 Carnegie Mellon University to Carnegie Mellon University (or inventors to CMU), an operating research institution, not a shell entity.
  2. Known asserter in the chain — Not present. Carnegie Mellon University is not identified as a known patent asserter (NPE).
  3. Repeat correspondent across the chain — Unclear. The firm ROTHWELL, FIGG, ERNST & MANBECK, P.C. appears once on reel 062085/0793. With only one record, there's no recurrence within this chain, and its presence alone does not signal an NPE pattern.
  4. Cascading transfers — Not present. Only one assignment is recorded.
  5. Pre-litigation transfer — Not present. No litigation has been identified for this patent.
  6. Bankruptcy fire-sale — Not present. Carnegie Mellon University is an active, operating institution.
  7. Privateering — Not present. There is no evidence to suggest privateering.
  8. Defensive aggregator (anti-NPE) — Not present. The patent is held by Carnegie Mellon University, which is not a defensive aggregator.

Verdict

Insufficient data.
Based on the single USPTO assignment record (Reel 062085/0793, recorded 2022-01-19) showing Carnegie Mellon University as both the assignor and assignee, there are no signals indicating NPE activity or a transfer away from the original operating institution. The patent appears to be held by its original assignee.
