Patent 11086361

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 inventor to Lepton Computing LLC, which is also the original assignee. There is no evidence of a transfer from an operating company to a shell entity.
  2. Known asserter in the chain — not present. Lepton Computing LLC is not explicitly listed as a known NPE on common public lists based on the provided information.
  3. Repeat correspondent across the chain — not present. Only one assignment is recorded, and thus there is no recurrence to observe. The correspondent is Stephen E. Delaporte, the inventor.
  4. Cascading transfers — not present. Only one assignment is recorded.
  5. Pre-litigation transfer — unclear. While there is litigation, the provided information does not contain enough detail about the specific timing of the litigation relative to any assignments beyond the initial one. The current litigation case was filed in 2026, and the only assignment record is from 2021. [cite: "US case filed in Texas Eastern District Court litigation https://portal.unifiedpatents.com/litigation/Texas%20Eastern%20District%20Court/case/2%3A26-cv-00338"]
  6. Bankruptcy fire-sale — not present. There is no indication of bankruptcy in the assignment records or legal status.
  7. Privateering — not present. There is no information to suggest this.
  8. Defensive aggregator (anti-NPE) — not present. The patent is not currently assigned to a defensive aggregator.

Verdict

Insufficient data. The only recorded assignment is from the inventor, Stephen E. Delaporte, to the original assignee, Lepton Computing LLC, recorded on 2021-03-18 (Reel 056477/0687). There are no subsequent assignments recorded that would indicate a transfer to a known NPE or other patterns. While litigation is ongoing, without a chain of assignments, it's not possible to determine if the assertion is by an NPE based solely on the provided assignment records.
