NPE / troll-pattern signals
- Shell-entity transfer — Not present. The only recorded assignment is from the inventor, Mark S. Berta, Jr., to Sea Swivel Inc. Sea Swivel Inc is an operating company that manufactures and sells products embodying the claims.
- Known asserter in the chain — Not present. Sea Swivel Inc is not identified as a known NPE. The legal events on Google Patents indicate "Family has litigation," with a US case filed in Florida Southern District Court and a PTAB case, but this does not inherently classify Sea Swivel Inc as an NPE [cite: litigation on Google Patents].
- Repeat correspondent across the chain — Unclear. Without access to the correspondent information for the initial assignment, it is not possible to assess if a correspondent is a repeat player.
- Cascading transfers — Not present. Only one assignment from the inventor to Sea Swivel Inc is indicated.
- Pre-litigation transfer — Unclear. Google Patents indicates "Family has litigation" with a US case filed in Florida Southern District Court in 2025, but there is no recorded assignment transferring the patent away from the original operating company, Sea Swivel Inc, prior to these litigation events. This suggests Sea Swivel Inc itself is the asserting entity.
- Bankruptcy fire-sale — Not present. There is no indication of Sea Swivel Inc. undergoing bankruptcy.
- Privateering — Not present. No evidence suggests a transfer to an NPE asserting on behalf of Sea Swivel Inc.
- Defensive aggregator (anti-NPE) — Not present. The patent is not currently assigned to a known defensive aggregator.
Verdict
Operating-company assertion. The patent was initially assigned from the inventor, Mark S. Berta, Jr., to Sea Swivel Inc. on 2024-09-26. Sea Swivel Inc. is an active operating company that produces and sells products directly related to the patent's claims (trolling motor swivel mounts). While the patent family is involved in litigation, there is no evidence of a transfer to a shell entity or known NPE, suggesting Sea Swivel Inc. is asserting its own patent.
