NPE / troll-pattern signals

  1. Shell-entity transfer — Not present. The only recorded assignment is from the individual inventor to Samsung Display Co Ltd, a large operating company.
  2. Known asserter in the chain — Not present. Samsung Display Co Ltd is an operating company, not a known NPE.
  3. Repeat correspondent across the chain — Not present. There is only one assignment recorded, with McDermott Will & Emery LLP as the correspondent. Without multiple assignments, recurrence cannot be determined.
  4. Cascading transfers — Not present. Only one assignment is recorded.
  5. Pre-litigation transfer — Not present. The only assignment (from inventor to Samsung Display) was recorded in February 2023. While litigation for the patent family was filed in 2025, the initial assignment is a standard inventor-to-company transfer, not indicative of pre-litigation transfer for assertion purposes by a new owner.
  6. Bankruptcy fire-sale — Not present. There is no indication of Samsung Display Co Ltd filing for bankruptcy.
  7. Privateering — Unclear. There is no public information in the patent details or search results to suggest a privateering arrangement.
  8. Defensive aggregator (anti-NPE) — Not present. The current owner is Samsung Display Co Ltd, an operating company, not a defensive aggregator.

Verdict

Operating-company assertion

This verdict is based on the single recorded assignment (Reel 060593/0187, recorded 2023-02-07) showing the patent transferred from the inventor to Samsung Display Co Ltd. Samsung Display Co Ltd is a large operating company that manufactures OLED displays. The litigation filed against this patent family appears to involve Samsung as the patent owner, defending its intellectual property as an operating company.
