Patent 10741071

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.

Inventors

Sean O'Sullivan. Employer at the time of filing: Carma Technology Ltd.

Original assignee

Carma Technology Ltd. It is unclear from the provided patent text whether Carma Technology Ltd. shipped a product embodying the claims. The primary line of business, as described in the patent, is focused on systems and methods for proxy communication in a shared transport system, which matches individuals with transport capacity. Its current status is "Active" according to Google Patents.

Assignment timeline

  • The Google Patents legal events section indicates an assignment to CARMA TECHNOLOGY LTD on 2020-01-08. This appears to be a re-assignment to the original assignee, possibly from the inventor. However, without direct access to the USPTO Assignment Search portal, the reel/frame and correspondent details for this event cannot be fully confirmed.
  • No other assignment records are explicitly listed in the provided Google Patents text. Without access to the USPTO Assignment Search portal, a complete chronological list of every recorded assignment, including reel/frame, conveyance type, assignor, assignee, correspondent, and context, cannot be generated with certainty beyond what's indicated.

NPE / troll-pattern signals

  1. Shell-entity transfer — unclear. The provided information doesn't explicitly state transfers to entities with names like "IP / Patents / Licensing / Holdings / Ventures," nor does it detail product lines or corporate addresses beyond the assignee's name.
  2. Known asserter in the chain — not present. The current assignee, Carma Technology Ltd, is not identified as a known asserter in the provided text or common NPE lists.
  3. Repeat correspondent across the chain — unclear. Without access to the USPTO Assignment Search portal, correspondent information cannot be determined.
  4. Cascading transfers — not present. Only one assignment event is mentioned, which is a re-assignment to the original assignee.
  5. Pre-litigation transfer — unclear. While the patent is currently involved in litigation (a US case filed in Texas Eastern District Court and a PTAB case IPR2026-00309), the provided assignment timeline doesn't show any transfers specifically within 6 months prior to the stated litigation dates that would suggest a pre-litigation transfer. The most recent assignment listed is to Carma Technology Ltd on 2020-01-08, and the earliest litigation mentioned is a US case filed in Texas Eastern District Court, without a specific filing date provided in the immediate context, but the PTAB case IPR2026-00309 is pending in 2026.
  6. Bankruptcy fire-sale — not present. No indication of bankruptcy proceedings for Carma Technology Ltd is provided.
  7. Privateering — unclear. There is no information to suggest an operating company transferred the patent to an NPE for assertion against competitors.
  8. Defensive aggregator (anti-NPE) — not present. The chain does not terminate at a known defensive aggregator.

Verdict

Insufficient data. The primary source for assignment records (USPTO Patent Assignment Search) was not directly accessed. The provided Google Patents data indicates an "Assigned to CARMA TECHNOLOGY LTD" event on 2020-01-08, which appears to be a re-assignment to the original assignee. Without access to the full assignment records, including reel/frame numbers and correspondent information, it is not possible to conclusively identify any NPE or patent-troll patterns.
