NPE / troll-pattern signals

  1. Shell-entity transfer — not present. The assignees, though showing minor name variations, consistently refer to "Radian Memory Systems", which is an operating company.
  2. Known asserter in the chain — not present. None of the listed assignees match known NPE lists.
  3. Repeat correspondent across the chain — not present. No correspondent information is available for the internal reassignments listed in Google Patents, and no assignments are recorded at the USPTO Assignment Center.
  4. Cascading transfers — not present. The listed reassignments are spaced out over several months and appear to be internal organizational changes rather than rapid transfers between distinct entities.
  5. Pre-litigation transfer — unclear. While litigation is noted, the provided information does not detail the exact timing of the first infringement suit in relation to any assignments.
  6. Bankruptcy fire-sale — not present. There is no indication of bankruptcy filings for Radian Memory Systems LLC.
  7. Privateering — not present. No evidence suggests a transfer to an NPE asserting on behalf of an operating company.
  8. Defensive aggregator (anti-NPE) — not present. The patent is currently held by Radian Memory Systems LLC, not a defensive aggregator.

Verdict

Insufficient data. While Google Patents indicates some reassignments, these appear to be internal corporate name changes or reorganizations within Radian Memory Systems, LLC, rather than transfers to third-party entities. Without recorded assignments at the USPTO Assignment Center, it is not possible to determine if the patent has been transferred to an NPE or is being asserted by an operating company.
