  2. Known asserter in the chain — Not present. Utherverse Digital Inc. is not identified as a known NPE.
  3. Repeat correspondent across the chain — Insufficient data. There is only one assignment recorded, so no pattern of recurrence can be established.
  4. Cascading transfers — Not present. Only a single assignment from inventors to the initial assignee is recorded.
  5. Pre-litigation transfer — Not present. No litigation has been identified for this patent.
  6. Bankruptcy fire-sale — Not present. There is no indication of bankruptcy for Utherverse Digital Inc.
  7. Privateering — Not present. No evidence suggests a privateering arrangement.

Verdict

Insufficient data. The only recorded assignment is from the individual inventors to Utherverse Digital Inc. (Reel 044598/0836). This single assignment does not provide enough information to identify any NPE or patent-troll patterns, as there are no subsequent transfers to analyze.
