Assignment history

Inventors, original assignee, and the chain of ownership recorded with the USPTO — including the correspondent attorney who recorded each assignment, since shell-LLC chains often share one repeat-player attorney even when the entity names look unrelated. Surfaces NPE / patent-troll patterns: shell-entity transfers, known asserters in the chain, repeat correspondent fingerprints, pre-litigation assignments, and bankruptcy fire-sales.

NPE / troll-pattern signals

Shell-entity transfer — present. The assignment from PANASONIC INTELLECTUAL PROPERTY CORPORATION OF AMERICA to PANELTOUCH TECHNOLOGIES LLC on 2024-04-27 (recorded 2024-05-02, Reel 060249/0569) suggests a shell entity transfer. Paneltouch Technologies LLC's name with "Technologies LLC" and the lack of readily apparent product offerings are indicative.
Known asserter in the chain — present. The Google Patents page for US11126025 indicates "Family has litigation" with a PTAB case IPR2025-01267 and a US case filed in Texas Eastern District Court (2:25-cv-00245). Unified Patents' PTAB data lists "Unified Patents PTAB Data" as the petitioner for IPR2025-01267, suggesting an assertion by Paneltouch Technologies LLC or an related entity.
Repeat correspondent across the chain — present. B. Noel Kivlin of Panasonic Corporation of North America is listed as the correspondent for both the 2020-04-10 assignment (Reel 051936/0401) and the 2023-08-31 assignment (Reel 058864/0055). This indicates an internal consistency within the Panasonic corporate structure for those transfers.
Cascading transfers — not present. The transfers occurred over several years (2020, 2023, 2024), not in quick succession within 24 months.
Pre-litigation transfer — unclear. The assignment to Paneltouch Technologies LLC was executed on 2024-04-27 and recorded on 2024-05-02 (Reel 060249/0569). The US case in Texas Eastern District Court (2:25-cv-00245) was filed in 2025. This transfer occurred within 12 months of the litigation filing, which could be considered a pre-litigation transfer, but not within the stricter 6-month definition often used.
Bankruptcy fire-sale — not present. There is no indication of Panasonic Liquid Crystal Display Co Ltd. or Panasonic Intellectual Property Corporation of America undergoing bankruptcy proceedings.
Privateering — unclear. While Panasonic transferred the patent to Paneltouch Technologies LLC, without further information from SEC filings or other reports, it's not possible to definitively state this is a privateering arrangement.
Defensive aggregator (anti-NPE) — not present. The chain ends with Paneltouch Technologies LLC, which appears to be an asserting entity rather than a defensive aggregator.

Verdict

NPE — high confidence. The transfer to Paneltouch Technologies LLC (Reel 060249/0569), a entity whose name suggests a licensing focus, combined with the presence of active litigation related to this patent family in the Texas Eastern District Court (case 2:25-cv-00245) strongly indicates an NPE assertion strategy.
