Assignment history

Surfaces NPE / patent-troll patterns: shell-entity transfers, known asserters in the chain, repeat correspondent fingerprints, pre-litigation assignments, and bankruptcy fire-sales.

  5. Pre-litigation transfer — unclear. While the patent has litigation associated with it (IPR2025-01191 and a US case in California Central District Court), there are no recorded assignments shortly before these litigation dates.
  6. Bankruptcy fire-sale — not present. There is no indication of Nine Stars Group (U.S.A) Inc. being in bankruptcy.

Verdict

Insufficient data. There is only one recorded assignment for US10822165, which is an initial transfer from the inventors to an operating company (Nine Stars Group (U.S.A) Inc.) prior to issuance. This does not provide sufficient evidence to indicate an NPE pattern.
