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 — not present. The initial assignment is from the inventors to Samsung Display Co Ltd, a known operating company.
Known asserter in the chain — not present. Samsung Display Co Ltd is not a known NPE.
Repeat correspondent across the chain — not present. Only one assignment is recorded, so no recurrence can be observed within this specific patent's chain. The correspondent, MCDANIEL & MARX, LLP, appears on the single recorded assignment (Reel 039434/0130).
Cascading transfers — not present. Only one assignment is recorded.
Pre-litigation transfer — unclear. The patent was issued in January 2020. Litigation was filed in 2025 (IPR2025-01476 and a US case in Texas Eastern District Court). There is a significant gap between the initial assignment (2017) and the litigation events, so no pre-litigation transfer is evident from the USPTO assignment records.
Bankruptcy fire-sale — not present. Samsung Display Co Ltd is an active operating company.
Privateering — not present. No evidence of privateering based on the assignment records.
Defensive aggregator (anti-NPE) — not present. The patent remains with Samsung Display Co Ltd.

Verdict

Insufficient data. Only one assignment, from the inventors to Samsung Display Co Ltd, is recorded for US10541279 (Reel 039434/0130). This is a standard initial assignment in patent prosecution. There is no evidence in the USPTO assignment records to suggest any NPE activity or transfer to a known NPE. The legal events on Google Patents indicate ongoing litigation, but the assignment records do not show transfers associated with these events.
