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

Shell-entity transfer — Unclear. The initial assignment was from the inventors to Furcifer Inc., which was an operating startup. The subsequent transfer was to Lannray Optoelectronics Zhenjiang Co Ltd (Reel 067353/0192). While the assignee's name suggests an operating company in the optoelectronics sector (Zhenjiang being a Chinese city), the provided data does not offer direct evidence of this entity shipping products embodying the claims of US 10,539,851. Therefore, it is not definitively clear if this transfer is to a licensing-only shell entity.
Known asserter in the chain — Not present. Neither Furcifer Inc. nor Lannray Optoelectronics Zhenjiang Co Ltd are identified on common public NPE lists.
Repeat correspondent across the chain — Unclear. Correspondent information, including attorney name, firm, and address, is not provided in the source patent text or Google Patents legal events for either recorded assignment.
Cascading transfers — Not present. Only one post-initial assignment is recorded (Reel 067353/0192), which does not constitute multiple consecutive assignments within a short timeframe.
Pre-litigation transfer — Not present. No litigation involving US Patent 10,539,851 has been identified as of May 19, 2026, meaning there is no pre-litigation transfer signal.
Bankruptcy fire-sale — Not present. There is no information in the provided data suggesting that Furcifer Inc. filed for bankruptcy.
Privateering — Unclear. There is no available information to indicate that this transfer represents a privateering arrangement where Furcifer Inc. is secretly funding assertion by Lannray Optoelectronics Zhenjiang Co Ltd.
Defensive aggregator (anti-NPE) — Not present. Lannray Optoelectronics Zhenjiang Co Ltd is not a recognized defensive aggregator like RPX, AST, LOT Network, or Unified Patents.

Verdict

Insufficient data. While the original assignee, Furcifer Inc., was an operating company in the electrochromic film sector, the patent was subsequently assigned to Lannray Optoelectronics Zhenjiang Co Ltd (Reel 067353/0192). The name of the current assignee suggests an operating company, but without explicit confirmation of their product shipments embodying the claims, or the presence of other typical NPE pattern signals (such as recurring correspondents or known NPE entities in the chain), a definitive determination regarding an NPE assertion or operating-company assertion cannot be made.
