2. Known asserter in the chain — not present. Neither "Radian Memory Systems, LLC" nor "Radian Memory Systems, Inc." appear on public NPE lists such as those maintained by RPX or Unified Patents.
3. Repeat correspondent across the chain — present. Brenton C. Smith of Morrison & Foerster LLP is listed as the correspondent for both recorded assignments (Reel 062921/0130 and Reel 068994/0936).
4. Cascading transfers — not present. Only two assignments are recorded for this patent, spanning a period of nearly three years, which does not indicate multiple consecutive transfers in a short timeframe.
5. Pre-litigation transfer — not present. The assignment from Radian Memory Systems, Inc. to Radian Memory Systems LLC was executed on 2024-05-20 (Reel 068994/0936).

8. Defensive aggregator (anti-NPE) — not present. The current assignee is Radian Memory Systems LLC, which is an operating company, not a defensive aggregator.

Verdict

Operating-company assertion. The patent is currently held by Radian Memory Systems LLC, an operating company that develops and sells storage products. The recorded assignments (Reel 062921/0130, Reel 068994/0936) reflect initial inventor assignment and subsequent internal corporate reorganizations between related entities (Radian Memory Systems, LLC and Radian Memory Systems, Inc.). Radian Memory Systems LLC is actively asserting the patent, as evidenced by litigation filed in the Texas Eastern District Court.
