NPE / troll-pattern signals

  1. Shell-entity transfer — present. The patent moved from JVCKenwood Corp., an operating company, to SOUNDCLEAR TECHNOLOGIES LLC. The assignee name "SOUNDCLEAR TECHNOLOGIES LLC" with the "LLC" suffix is suggestive of a licensing entity. [cite: 2024-06-25 (executed) / recorded 2024-06-25 — Reel 063380/0616]

  2. Known asserter in the chain — unclear. While SOUNDCLEAR TECHNOLOGIES LLC is the current assignee, it is not listed on the commonly cited public NPE lists from RPX or Unified Patents as of today's date. However, its name structure and the context of the transfer suggest a potential for assertion.

  3. Repeat correspondent across the chain — not present. Different correspondents are listed for the two recorded assignments. JVC KENWOOD CORPORATION is listed for the initial assignment from the inventor, and ROTHWELL, FIGG, ERNST & MANBECK, P.C. is listed for the assignment to SOUNDCLEAR TECHNOLOGIES LLC.

  4. Cascading transfers — not present. Only one post-issuance assignment is recorded.

  5. Pre-litigation transfer — present. US case 3:24-cv-00540 was filed in Virginia Eastern District Court in 2024. The assignment to Soundclear Technologies LLC was executed and recorded on 2024-06-25 (Reel 063380/0616), which is less than 6 months before this litigation.

  6. Bankruptcy fire-sale — not present. There is no indication of bankruptcy proceedings for JVCKenwood Corp.

  7. Privateering — unclear. No SEC filings or public reports explicitly state a privateering arrangement.

  8. Defensive aggregator (anti-NPE) — not present. The chain does not end at a known defensive aggregator.

Verdict

NPE — high confidence. The transfer from JVCKenwood Corp. to SOUNDCLEAR TECHNOLOGIES LLC, a likely shell entity (indicated by the LLC suffix and lack of known products), coupled with the assignment occurring within six months of litigation being filed against this patent family, strongly suggests an NPE assertion strategy.
