NPE / troll-pattern signals

  1. Shell-entity transfer — Not present. The transfers involve Centripetal Networks, Inc. and Centripetal Networks, LLC, which are the same operating company.
  2. Known asserter in the chain — Not present. Centripetal Networks LLC is not on common NPE lists.
  3. Repeat correspondent across the chain — Present. BLANK ROME LLP appears as the correspondent for both the initial assignment from the inventors (2019-07-22 / Reel 005230/0173) and the Change of Name (2023-01-20 / Reel 005952/0979).
  4. Cascading transfers — Not present. There are only two recorded events: one from the inventors to the initial company and a subsequent change of name for that same company. These are not cascading transfers.
  5. Pre-litigation transfer — Unclear. While there is litigation associated with this patent family, the specific date of the first suit relative to the assignment records is not provided in a way that allows for a definitive determination here. However, the existing transfers are internal/foundational rather than indicative of external assertion preparation.
  6. Bankruptcy fire-sale — Not present. There is no indication of bankruptcy proceedings for Centripetal Networks.
  7. Privateering — Not present. No evidence suggests that Centripetal Networks LLC is transferring patents for assertion on its behalf.
  8. Defensive aggregator (anti-NPE) — Not present. The chain does not terminate at a known defensive aggregator.

Verdict

Operating-company assertion

The assignment records show an initial transfer from the inventors to Centripetal Networks, Inc. and a subsequent change of name to Centripetal Networks, LLC (Reel 005230/0173, 2019-07-22; Reel 005952/0979, 2023-01-20). Centripetal Networks is known as an operating company that develops and sells cybersecurity products. The detected litigation in the family suggests an assertion strategy by an operating company.
