NPE / troll-pattern signals

1. Shell-entity transfer — unclear. While Skysong Innovations, LLC is a technology transfer arm of Arizona State University, it's not explicitly stated if they engage solely in licensing or if the patent relates to products in commerce. Their name does not explicitly contain "IP / Patents / Licensing / Holdings / Ventures".

2. Known asserter in the chain — not present. None of the named assignees (Arizona State University Downtown Phoenix campus, Arizona Board of Regents on Behalf of Arizona State University, Skysong Innovations, LLC) are listed as known NPEs in common directories or the provided text.

3. Repeat correspondent across the chain — not present. Only one correspondent is listed in the provided assignment records, MICHAEL BEST & FRIEDRICH LLP, for the initial assignment from inventors to the Board of Regents. No recurrence is evident.

4. Cascading transfers — not present. There are two assignments recorded, with a gap between them, not meeting the criteria of multiple consecutive assignments in <24 months.

5. Pre-litigation transfer — unclear. The patent has litigation associated with it (IPR2025-01399, US cases in Texas Western and Eastern District Courts), but the exact filing dates of these suits relative to the assignment to Skysong Innovations, LLC (2025-01-30) are not precisely enough specified in the provided text to definitively make this call.

6. Bankruptcy fire-sale — not present. No indication of bankruptcy for any entity in the chain.

7. Privateering — not present. No evidence provided to suggest an operating company transferred to an NPE for assertion against competitors.

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

Verdict

Insufficient data.
While the patent is actively involved in litigation, the provided information, especially the lack of complete USPTO assignment records (reel/frame for the most recent assignment) and definitive information on Skysong Innovations, LLC's productization or assertion model, prevents a confident classification as an NPE. The initial assignments are consistent with standard university technology transfer. To verify for certain, a direct search on the USPTO Assignment Center would be necessary for complete reel/frame and correspondent information for the Skysong Innovations, LLC assignment and further investigation into Skysong Innovations, LLC's business practices.
