Patent 11740801

Assignment history

Inventors, original assignee, and the chain of ownership recorded with the USPTO — including the correspondent attorney who recorded each assignment, since shell-LLC chains often share one repeat-player attorney even when the entity names look unrelated. Surfaces NPE / patent-troll patterns: shell-entity transfers, known asserters in the chain, repeat correspondent fingerprints, pre-litigation assignments, and bankruptcy fire-sales.

NPE / troll-pattern signals

Shell-entity transfer — Not present. The transfers involve entities named "Radian Memory Systems, LLC" and "Radian Memory Systems, Inc.", which appear to be related operating entities rather than shell companies.
Known asserter in the chain — Not present. None of the assignees (Radian Memory Systems, LLC, Radian Memory Systems, Inc., RADIAN MEMORY SYSTEMS LLC) match known public NPE lists.
Repeat correspondent across the chain — Present. Scott W. Kelley of Radian Memory Systems, LLC is listed as the correspondent for all three recorded assignments (Reel 059952/0150, Reel 059952/0151, and Reel 063462/0130).
Cascading transfers — Not present. There are two transfers in 2022 and one in 2024, but they appear to be internal reorganizations/name changes within the same company rather than rapid, sequential transfers through unrelated entities.
Pre-litigation transfer — Unclear. The patent was published on August 29, 2023. The earliest identified litigation event is a US case filed in Texas Eastern District Court in 2024. The assignment on 2024-05-20 / recorded 2024-05-22 occurs before this 2024 litigation, which could be considered within 6 months depending on the exact filing date of the suit, but the nature of the transfer (Inc. to LLC of the same name) suggests internal re-organization rather than an assertion-enabling transfer.
Bankruptcy fire-sale — Not present. There is no indication of bankruptcy proceedings for Radian Memory Systems.
Privateering — Not present. No evidence in the assignment records or publicly available information suggests privateering activity.
Defensive aggregator (anti-NPE) — Not present. The chain does not terminate at any known defensive aggregators.

Verdict

Operating-company assertion. The assignment history shows transfers between "Radian Memory Systems, LLC" and "Radian Memory Systems, Inc." (Reel 059952/0151, Reel 063462/0130), which appear to be internal reorganizations of an operating company. Radian Memory Systems LLC is identified as the current assignee and engages in product development. Litigation is present (PTAB case IPR2025-01350 and a US case in Texas Eastern District Court), but without other NPE signals, it points to an operating company asserting its intellectual property.
