NPE / troll-pattern signals

1. Shell-entity transfer — Not present. The transfers observed are between different legal forms of the same operating company, Radian Memory Systems. There is no indication of a transfer to a licensing-only LLC.
2. Known asserter in the chain — Not present. Radian Memory Systems LLC is not on the provided list of known NPEs or commonly identified as such by RPX or Unified Patents in my training data.
3. Repeat correspondent across the chain — Present. The correspondent "LAW OFFICE OF ROBERT LERCARIA, 15127 SKYVIEW WAY, SAN JOSE, CALIFORNIA 95139" appears for all three recorded assignments: Reel 057053/0002, Reel 057053/0003, and Reel 063674/0971. This indicates consistency in legal representation for Radian Memory Systems.
4. Cascading transfers — Not present. While there are two assignments on the same day in 2021, they represent an initial inventor assignment and an immediate corporate name change, not a series of transfers through different entities. The subsequent transfer in 2024 is also a corporate name change.
5. Pre-litigation transfer — Unclear. The litigation filed in Texas Eastern District Court (2:24-cv-01073) began in 2024. The most recent assignment (Radian Memory Systems, Inc. to RADIAN MEMORY SYSTEMS LLC) was executed and recorded on 2024-05-20 (Reel 063674/0971). Without a precise filing date for the Texas case, it's unclear if this assignment falls within 6 months prior to the suit. The patent itself does not provide the exact filing date of the Texas lawsuit, only that it was filed in 2024.
6. Bankruptcy fire-sale — Not present. There is no information to suggest Radian Memory Systems underwent bankruptcy proceedings.
7. Privateering — Not present. No evidence from the assignment records or the patent text suggests privateering.
8. Defensive aggregator (anti-NPE) — Not present. The current assignee is Radian Memory Systems LLC, an operating company, not a defensive aggregator.

Verdict

Operating-company assertion
The assignment chain primarily reflects internal corporate reorganizations (name changes between LLC and Inc. forms of Radian Memory Systems) as evidenced by Reel 057053/0003 and Reel 063674/0971. The initial assignment on Reel 057053/0002 is from the inventors to Radian Memory Systems, LLC, which is typical for an operating company. While there is ongoing litigation, the patent remains with the operating company, Radian Memory Systems LLC.
