NPE / troll-pattern signals

1. Shell-entity transfer — not present. The transfers involve the original inventors assigning to the operating company (Theragun, Inc./Therabody, Inc.) and a security interest granted by the operating company. There is no indication of transfer to a licensing-only LLC.
2. Known asserter in the chain — not present. None of the assignees (Theragun, Inc., Therabody, Inc., JPMorgan Chase Bank, N.A.) are publicly known NPEs.
3. Repeat correspondent across the chain — present. Michael J. Fegin of Fakhimi & Fegin LLP is listed as the correspondent for both the assignment from the inventors to Theragun, Inc. (Reel 006509/0074) and the subsequent change of name from Theragun, Inc. to Therabody, Inc. (Reel 006509/0075).
4. Cascading transfers — not present. The transfers are separated by a reasonable time frame and reflect inventor assignment, a corporate name change, and a security interest, not multiple quick transfers between shell entities.
5. Pre-litigation transfer — unclear. While the patent notes "Family has litigation" filed on 2019-11-06, this patent (US12396919) was filed in 2024 and issued in 2025, and no specific litigation for this patent number was found. The assignments occurred after the stated "First worldwide family litigation filed" date, but there is no direct evidence linking these assignments to specific litigation for this patent.
6. Bankruptcy fire-sale — not present. There is no indication that Therabody Inc. has filed for bankruptcy or that the patents were sold in such proceedings.
7. Privateering — not present. The patent remains with the original operating company, Therabody Inc.
8. Defensive aggregator (anti-NPE) — not present. The chain does not terminate at any known defensive aggregators.

Verdict

Insufficient data. The assignment records show the transfer from inventors to the operating company (Theragun/Therabody Inc.) and a subsequent security interest granted by Therabody Inc. to JPMorgan Chase Bank, N.A.. While a repeat correspondent appears for the initial transfers, there are no other strong signals like shell-entity transfers or known asserters in the chain, nor is there clear evidence of pre-litigation transfer specific to this patent, to confidently label it as an NPE asset.
