Without further details on the nature of these specific lawsuits (e.g., against competitors or non-competitors), it is unclear if this patent is involved in "privateering" actions. However, the patent itself has not been transferred to a third party.
  8. Defensive aggregator (anti-NPE) — Not present. The patent is currently owned by Credo Technology Group Ltd and has not been acquired by a defensive aggregator.

Verdict

Operating-company assertion. The patent US11012252 remains assigned to its original operating company, Credo Technology Group Ltd, and no subsequent assignments are recorded with the USPTO Assignment Center (search results: "No matching records were found for the query." on 2026-05-21). The litigation noted in the patent summary suggests assertion activity, which, given the continued ownership by an operating company, points to operating-company assertion.
