NPE / troll-pattern signals

1. Shell-entity transfer — Not present. The only recorded transfer is from the individual inventors to Dental Monitoring SAS, an operating company.
2. Known asserter in the chain — Not present. Dental Monitoring SAS is an operating company and not listed as a known NPE.
3. Repeat correspondent across the chain — Not present. There is only one recorded assignment, so no recurrence can be observed.
4. Cascading transfers — Not present. Only a single assignment from inventors to the operating company is recorded.
5. Pre-litigation transfer — Unclear. While the patent is involved in litigation (CAFC cases 25-1752 and 24-2270), the only recorded assignment is from 2018-10-16, well before the litigation dates (2024 and 2025 filings), and is an initial inventor-to-company transfer.
6. Bankruptcy fire-sale — Not present. No evidence suggests Dental Monitoring SAS has filed for bankruptcy, and the recorded assignment is not indicative of such.
7. Privateering — Not present. No evidence of a transfer to an NPE on behalf of Dental Monitoring SAS.
8. Defensive aggregator (anti-NPE) — Not present. The patent remains with the original operating assignee.

Verdict

Insufficient data. The only recorded assignment is the initial transfer from the inventors to the original operating assignee, Dental Monitoring SAS (Reel 046648/0279, recorded 2018-10-16). There are no subsequent assignments that would indicate a change in ownership or a transfer to a non-practicing entity. Therefore, based solely on the assignment records, there is insufficient data to identify any NPE/troll patterns.
