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 — unclear. Furcifer Inc. appears in the assignment chain, receiving the patent from the inventors. While the name doesn't explicitly suggest "IP/Patents/Holdings", further information on its business and address is needed to confirm if it acts as a shell entity. The re-assignment back to Lannray Optoelectronics Zhenjiang Co Ltd could indicate a temporary holding or a change in strategy.

  2. Known asserter in the chain — not present. Neither Furcifer Inc. nor Lannray Optoelectronics Zhenjiang Co Ltd are identified as known NPEs in standard directories.

  3. Repeat correspondent across the chain — unclear. The provided text from Google Patents does not include correspondent information for the assignments, making it impossible to assess this signal.

  4. Cascading transfers — not present. There are two transfers in total, spanning over 5 years between the initial transfer from inventors to Furcifer and the subsequent transfer back to Lannray. This does not suggest rapid, consecutive transfers characteristic of cascading.

  5. Pre-litigation transfer — unclear. No litigation is currently identified for US12502870 as of April 26, 2026. Therefore, a pre-litigation transfer cannot be confirmed.

  6. Bankruptcy fire-sale — not present. There is no information in the provided text to suggest that any of the assignors filed for bankruptcy.

  7. Privateering — unclear. There's no public information in the provided text to suggest privateering activities.

  8. Defensive aggregator (anti-NPE) — not present. The chain does not terminate at a known defensive aggregator.

Verdict

Insufficient data. While there was an assignment from the inventors to Furcifer Inc. and then back to Lannray Optoelectronics Zhenjiang Co Ltd, the lack of information regarding the business activities of Furcifer Inc. and the absence of correspondent details for the assignments make it impossible to confidently identify any NPE patterns. The initial transfer to Furcifer Inc. was executed in 2018-11-12 and recorded in 2024-03-18, followed by a re-assignment to Lannray Optoelectronics (Zhenjiang) Co. Ltd. executed on 2024-09-23 and recorded on 2024-09-24.
