NPE / troll-pattern signals

  1. Shell-entity transfer — not present. The sole assignee, LG Electronics Inc., is a well-known operating company.
  2. Known asserter in the chain — not present. The sole assignee, LG Electronics Inc., is not on common NPE lists.
  3. Repeat correspondent across the chain — not present. There is only one assignment record, and no recurring correspondent.
  4. Cascading transfers — not present. There is only one assignment record.
  5. Pre-litigation transfer — unclear. While there is litigation associated with this patent family (mentioned on Google Patents), the assignment record (2018-05-02) predates the patent grant (2019-05-28) and the first recorded litigation event (2025-07-29 PTAB case IPR2025-01099) by a significant margin. Without details on when the "first worldwide family litigation" was filed (not specifically dated in the provided text), it's hard to definitively say.
  6. Bankruptcy fire-sale — not present. There is no indication of LG Electronics Inc. being in bankruptcy.
  7. Privateering — not present. There is no evidence to suggest this.
  8. Defensive aggregator (anti-NPE) — not present. The patent is owned by LG Electronics Inc.

Verdict

Insufficient data. While the patent is currently owned by an operating company (LG Electronics Inc.) which suggests operating-company assertion if litigation occurs, there is only one assignment record in the USPTO Assignment Center, which is from the inventors to the original assignee. This single assignment is typical for initial patent ownership and does not provide enough information to identify NPE or patent-troll patterns.
