Patent 11017668

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

  1. Shell-entity transfer — not present. There is no evidence of a transfer from an operating assignee to a licensing-only LLC.
  2. Known asserter in the chain — not present. No known NPEs are listed as assignees.
  3. Repeat correspondent across the chain — not present. With no assignment records, there is no correspondent information to analyze for recurrence.
  4. Cascading transfers — not present. There are no recorded assignments.
  5. Pre-litigation transfer — unclear. While litigation is noted in Google Patents ("PTAB case IPR2026-00308 filed (Pending)" and "US case filed in Texas Eastern District Court 2:25-cv-00029"), the patent shows no recorded assignments to assess a pre-litigation transfer.
  6. Bankruptcy fire-sale — not present. No indication of bankruptcy proceedings for Carma Technology Ltd.
  7. Privateering — not present. No evidence in the public record suggests a privateering arrangement.
  8. Defensive aggregator (anti-NPE) — not present. The patent is currently assigned to Carma Technology Ltd.

Verdict

Insufficient data. There are no post-issuance assignment records for US11017668 in the USPTO Assignment Center (https://assignmentcenter.uspto.gov/patent/index.html). The "Assigned to Carma Technology Limited" event listed in Google Patents on 2020-08-03 likely refers to the initial assignment from the inventor to the company upon application filing, not a subsequent transfer indicative of NPE activity.
