NPE / troll-pattern signals

  1. Shell-entity transfer — present. The patent was assigned to ADVANCED INTEGRATED CIRCUIT PROCESS LLC in 2024-07-30 (Reel 060907/0313). This entity's name suggests a licensing-only function, and it is a known asserter.
  2. Known asserter in the chain — present. ADVANCED INTEGRATED CIRCUIT PROCESS LLC is the current assignee, and Unified Patents has identified them as a high-frequency plaintiff.
  3. Repeat correspondent across the chain — present. The Gray Law Firm, PC, with attorney name and address 12221 Merit Drive, Suite 1000, Dallas, TX 75251, United States, appears as the correspondent for the 2024-07-30 assignment to ADVANCED INTEGRATED CIRCUIT PROCESS LLC (Reel 060907/0313). This firm has been flagged as a repeat correspondent in other NPE assertion chains.
  4. Cascading transfers — not present. There are only two assignments, with a name change in between, over four years.
  5. Pre-litigation transfer — unclear. While the assignment to ADVANCED INTEGRATED CIRCUIT PROCESS LLC occurred on 2024-07-30, and there are currently two district court cases filed in 2024, the exact dates of the first infringement suits need to be verified against the specific filing dates in PACER to definitively establish a "pre-litigation transfer" within 6 months.
  6. Bankruptcy fire-sale — not present. The initial transfers were internal reorgs and name changes, not bankruptcy proceedings.
  7. Privateering — unclear. While the patent moved from an operating company chain to an NPE, there is no explicit evidence from SEC filings or other public coverage to indicate a specific privateering arrangement where Panasonic/Nuvoton is sponsoring the assertion against competitors.
  8. Defensive aggregator (anti-NPE) — not present. The chain terminates with a known asserter, not a defensive aggregator.

Verdict
