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 — unclear. The original assignee, AKW Analytics Inc., and the subsequent assignees (the inventors) do not immediately suggest shell entities based on their names. Without further information on their business activities or addresses, this signal remains unclear.
- Known asserter in the chain — not present. None of the named assignees (AKW Analytics Inc., or the individual inventors) appear on common NPE lists.
- Repeat correspondent across the chain — present. The correspondent "BROWDY AND NEIMARK, P.L.L.C." appears on both the 2017-01-18 (Reel 040187/0038) and 2020-03-27 (Reel 049397/0885) assignments.
- Cascading transfers — not present. There are only two assignments recorded, which does not constitute cascading transfers.
- Pre-litigation transfer — unclear. No litigation has been identified for this patent, so this signal cannot be assessed.
- Bankruptcy fire-sale — not present. There is no indication of bankruptcy proceedings for AKW Analytics Inc.
- Privateering — unclear. There is no public information to suggest a privateering arrangement.
- Defensive aggregator (anti-NPE) — not present. The patent has not been assigned to any known defensive aggregators.
Verdict
Insufficient data (only the original assignment and a reassignment to inventors).
The recorded assignment history shows a transfer from the initial assignee (AKW Analytics Inc.) back to the inventors. While the same correspondent handled both recordings, there is no other evidence to suggest an NPE pattern, such as transfers to known assertion entities, cascading transfers, or shell company indicators. Further information about the inventors' current activities or any product commercialization would be needed for a more definitive assessment.
