NPE / troll-pattern signals

1. Shell-entity transfer — not present. The sole recorded assignee, Gudeng Precision Industrial Co Ltd, is an operating company that manufactures products embodying the claims.
2. Known asserter in the chain — not present. Gudeng Precision Industrial Co Ltd is not identified on common NPE lists.

5. Pre-litigation transfer — not present. The patent was issued on July 1, 2025, and no litigation has been filed as of April 30, 2026. There are no transfers within 6 months prior to any litigation.

Verdict

Insufficient data. The only recorded assignment is the initial transfer from the inventors to the operating company, Gudeng Precision Industrial Co Ltd, on August 8, 2022 (Reel 059908/0747). There are no subsequent assignments that would provide signals for NPE/troll patterns, such as transfers to shell entities, cascading transfers, or known asserters in the chain. Therefore, based solely on the assignment records, it is not possible to determine if this patent is involved in NPE assertion patterns. The patent remains with its original operating assignee.
