NPE / troll-pattern signals

  1. Shell-entity transfer — present. The assignment from JVCKENWOOD CORPORATION to SOUNDCLEAR TECHNOLOGIES LLC (Reel 059905/0053, recorded 2023-09-22) strongly suggests a shell entity transfer. "SOUNDCLEAR TECHNOLOGIES LLC" has a name suffix suggesting a non-operating entity, and there is no public record of Soundclear Technologies LLC shipping products embodying the claims. Furthermore, Unified Patents lists Soundclear Technologies LLC as an NPE.

  2. Known asserter in the chain — present. Soundclear Technologies LLC, the current assignee, is identified as a high-frequency plaintiff by Unified Patents.

  3. Repeat correspondent across the chain — not present. The correspondent for the first assignment was BROWDY AND NEIMARK, PLLC, and for the second assignment was NATH, LAWRENCE S. Neither attorney/firm appears multiple times in this chain for this specific patent.

  4. Cascading transfers — not present. There are only two assignments recorded, with a gap of over 10 years between the first and second, which does not indicate cascading transfers.

  5. Pre-litigation transfer — present. The patent was assigned to Soundclear Technologies LLC on 2023-09-21. Unified Patents reports litigation against Soundclear Technologies LLC filed in the Virginia Eastern District Court with cases filed in 2024 (e.g., 1:24-cv-00729, 2:24-cv-00321, 1:24-cv-00728), which is within 6 months of the assignment date.

  6. Bankruptcy fire-sale — not present. JVCKenwood Corp. is an active, operating company and there is no indication of bankruptcy in the assignment records or other readily available information.

  7. Privateering — unclear. While the patent was transferred from an operating company (JVCKenwood Corp.) to an NPE (Soundclear Technologies LLC), there is no specific information in the provided data (e.g., SEC filings or specific news coverage) to confirm that JVCKenwood Corp. is directing Soundclear Technologies LLC to assert on its behalf against competitors.

  8. Defensive aggregator (anti-NPE) — not present. The current assignee, Soundclear Technologies LLC, is an NPE, not a defensive aggregator.

Verdict

NPE — high confidence

This verdict is based on multiple strong signals: the transfer to Soundclear Technologies LLC (Reel 059905/0053, recorded 2023-09-22), which is a known NPE as identified by Unified Patents, and the subsequent pre-litigation transfer, as evidenced by district court cases filed in 2024 within six months of the assignment.
