NPE / troll-pattern signals

1. Shell-entity transfer — unclear. While there's a transfer between Data Health Partners Inc. and Parallax Behavioral Health, Inc. (and back), it's not clear from the provided data if Parallax Behavioral Health is a licensing-only shell entity. The names themselves don't strongly suggest a shell, and no product information or registered-agent addresses are available to confirm.
2. Known asserter in the chain — not present. None of the assignors or assignees (Data Health Partners Inc., Parallax Behavioral Health Inc., Melamed Shahla) are recognized as known NPEs based on the provided list or general knowledge without further investigation.
3. Repeat correspondent across the chain — present. Lindsey Crowder of 2147 E. REDONDO AVE., MESA, AZ 85204 appears as the correspondent for three assignments: Reel 059958/0641 (2021-12-29), Reel 060893/0885 (2022-08-11), and Reel 061324/0970 (2022-12-22). This recurrence indicates a consistent legal representative for Data Health Partners Inc. and Parallax Behavioral Health, Inc.
4. Cascading transfers — not present. While there are transfers within a relatively short period, they involve Data Health Partners Inc. and Parallax Behavioral Health, Inc., suggesting internal reassignments rather than a rapid succession through unrelated shell entities. The transfers are not between different, new LLCs.
5. Pre-litigation transfer — unclear. The "Family has litigation" section indicates a US case filed in Delaware District Court (case 1:23-cv-00160) and a first worldwide family litigation filed in 2014. The last assignment to Melamed Shahla was recorded on 2024-03-27. Without the exact filing date of the Delaware District Court case, it's impossible to confirm if the assignment to Melamed Shahla was within 6 months of litigation specific to this patent. Google Patents shows the litigation against this patent was filed March 2023, so the assignment to Melamed Shahla occurred after litigation had started.
6. Bankruptcy fire-sale — not present. There is no indication of any of the assignors or assignees filing for Chapter 7 or 11 bankruptcy. The last assignment to Melamed Shahla was court-ordered, but not explicitly stated to be from bankruptcy proceedings.
7. Privateering — not present. There is no evidence or indication of an operating company transferring the patent to an NPE to assert against competitors on its behalf.
8. Defensive aggregator (anti-NPE) — not present. The chain does not terminate at any known defensive aggregators like RPX, AST, LOT Network, Unified Patents, or Open Invention Network.

Verdict

Insufficient data. While there is a recurring correspondent (Lindsey Crowder) on multiple assignments (Reel 059958/0641, Reel 060893/0885, Reel 061324/0970), which is a weak signal, there is no strong indication of shell entities or known NPE involvement. The final assignment to Melamed Shahla was court-ordered for judgment enforcement, which is an unusual pattern for typical NPE activity. Further, there is not enough information to determine if Data Health Partners Inc. is an operating company or a pure licensing entity.
