NPE / troll-pattern signals

  1. Shell-entity transferpresent. The patent was transferred from JVCKenwood Corporation, an operating company, to Advanced Coding Technologies LLC. The assignee's name (ending in "LLC" and including "Technologies") is indicative of a licensing-only entity, and Advanced Coding Technologies LLC is listed as an asserter by Unified Patents. (Reel 052445/0569, executed 2022-03-24 / recorded 2022-04-14)

  2. Known asserter in the chainpresent. Advanced Coding Technologies LLC is identified by Unified Patents as a patent assertion entity (NPE). (Reel 052445/0569, executed 2022-03-24 / recorded 2022-04-14)

  3. Repeat correspondent across the chainpresent. John M. Wynne, JOHN M. WYNNE, ATTORNEY AT LAW, served as the correspondent for the transfer to Advanced Coding Technologies LLC. Although he does not recur within this patent's specific assignment chain, public records and NPE databases associate him with numerous patent assertion entities, indicating a pattern of representing such entities. (Reel 052445/0569, correspondent John M. Wynne, JOHN M. WYNNE, ATTORNEY AT LAW)

  4. Cascading transfersnot present. There are only two distinct assignments (excluding the inventor assignment to the original assignee), not multiple consecutive transfers through chained LLCs.

  5. Pre-litigation transferpresent. The assignment from JVCKenwood Corporation to Advanced Coding Technologies LLC was executed on 2022-03-24 and recorded on 2022-04-14 (Reel 052445/0569). Google Patents indicates that litigation (case 2:22-cv-00501 in the Texas Eastern District Court) involving this patent was filed in 2022, which is concurrent with or immediately following the patent transfer, suggesting the transfer was arranged to enable assertion.

  6. Bankruptcy fire-salenot present. The assignor, JVCKenwood Corporation, is an active operating company and no bankruptcy proceedings were indicated.

  7. Privateeringunclear. While the patent moved from an operating company to an NPE, there is no publicly available information in the provided sources to confirm that Advanced Coding Technologies LLC is asserting this patent on behalf of JVCKenwood or its competitors.

  8. Defensive aggregator (anti-NPE)not present. The chain terminates with Advanced Coding Technologies LLC, an identified asserter, not a defensive aggregator like RPX or Unified Patents.

Verdict

NPE — high confidence
This verdict is supported by the transfer of the patent from an operating company (JVCKenwood Corp) to Advanced Coding Technologies LLC, which is a known patent assertion entity (Reel 052445/0569). Furthermore, this transfer occurred concurrently with or just prior to the first recorded litigation involving the patent in 2022, a strong indicator of an assertion-driven transfer (Reel 052445/0569).
