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 inventors to Samsung Display Co Ltd, a known operating company.
  2. Known asserter in the chain — not present. Samsung Display Co Ltd is an operating company and not listed as a known NPE.
  3. Repeat correspondent across the chain — present. BAE, TERENCE B. of LEE & HAN, P.C. is listed as the correspondent for the assignment recorded on 2017-09-28 (Reel 043003/0501).
  4. Cascading transfers — not present. There is only one recorded assignment for this patent.
  5. Pre-litigation transfer — unclear. There is litigation associated with this patent (IPR2025-01498 and a US case filed in Texas Eastern District Court), but the single assignment pre-dates the litigation significantly. More recent transfers that are not recorded in the Assignment Center would be needed to make a clear determination.
  6. Bankruptcy fire-sale — not present. Samsung Display Co Ltd is an active operating company.
  7. Privateering — not present. No evidence in the assignment record suggests this.
  8. Defensive aggregator (anti-NPE) — not present. The patent is currently assigned to an operating company.

Verdict

Insufficient data. While the patent is currently involved in litigation, the recorded assignment chain only shows the initial transfer from the inventors to Samsung Display Co Ltd. There are no further recorded assignments to suggest a transfer to a shell entity or known NPE, making it impossible to confidently label it as an NPE assertion based solely on the provided assignment records.
