NPE / troll-pattern signals

1. Shell-entity transfer — Present. The transfer on 2024-05-02 (Reel 062758/0104) from "Radian Memory Systems, Inc." to "RADIAN MEMORY SYSTEMS LLC" (a Texas LLC) appears to be a shell-entity transfer. The new Radian Memory Systems LLC is tied to Fortress Investment Group LLC, an entity known to be involved in patent assertion. The address listed for the assignee (c/o Fortress Investment Group, 1345 Avenue of the Americas, 46th Floor, New York, New York, 10105, US in related court documents, or 6275 West Plano Parkway, Suite 500, Plano, Texas, U.S.A. 75093 as principal place of business) aligns with a licensing-focused entity. Radian Memory Systems LLC is described as a plaintiff tied to Fortress Investment Group LLC, and has sued Samsung.
2. Known asserter in the chain — Present. The current assignee, RADIAN MEMORY SYSTEMS LLC, is tied to Fortress Investment Group LLC. Fortress Investment Group is widely recognized as a major player in patent assertion. Radian Memory Systems LLC is currently engaged in patent infringement litigation against Samsung.
3. Repeat correspondent across the chain — Not present. There is no recurrence of the same correspondent across the assignment chain for this patent. Shival Virmani, the correspondent for the 2024-05-02 assignment (Reel 062758/0104), is the Chief IP and Licensing Officer for Radian Memory Systems, and not explicitly a repeat correspondent from multiple links or known NPE assertion lists.
4. Cascading transfers — Not present. While there were two assignments from the individual inventors to Radian Memory Systems, LLC, recorded on the same date, and then a name change, the only actual transfer of ownership to a different entity (the one tied to Fortress) occurred over a year later. This does not represent cascading transfers in under 24 months through chained LLCs.
5. Pre-litigation transfer — Present. The assignment to RADIAN MEMORY SYSTEMS LLC was executed on 2024-05-02 and recorded on 2024-05-13 (Reel 062758/0104). Radian Memory Systems LLC filed a patent infringement lawsuit against Samsung on December 23, 2024. This transfer occurred approximately seven months before the litigation filing, falling within the pre-litigation transfer pattern.
6. Bankruptcy fire-sale — Not present. There is no indication of bankruptcy proceedings for the original assignee, Radian Memory Systems, Inc.
7. Privateering — Unclear. While Radian Memory Systems Inc. (the original operating company) transferred its patents to Radian Memory Systems LLC (the asserting entity tied to Fortress), and the asserting entity is suing Samsung, it is not explicitly stated whether this is occurring on behalf of Radian Memory Systems Inc. against a direct competitor. Some sources state that Radian Memory Systems was "cast out by the industry" suggesting they are no longer an operating entity, but this doesn't definitively confirm privateering for another operating company.
8. Defensive aggregator (anti-NPE) — Not present. The chain ends with Radian Memory Systems LLC, an entity involved in patent assertion, not a defensive aggregator.

Verdict

NPE — high confidence

This verdict is driven by several strong signals. The transfer on 2024-05-02 to "RADIAN MEMORY SYSTEMS LLC" (Reel 062758/0104) is a shell-entity transfer to an entity tied to Fortress Investment Group LLC, a known patent asserter. Furthermore, this assignment occurred approximately seven months prior to the filing of an infringement lawsuit against Samsung. These factors collectively indicate a high likelihood of NPE activity.
