Patent 12125496

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.

I am unable to perform live searches on the USPTO Patent Assignment Search database at assignmentcenter.uspto.gov or assignment.uspto.gov/patent/index.html. Therefore, I cannot reconstruct the full assignment record for US patent 12125496 to identify any NPE/patent-troll patterns.

My previous search for "US12125496B1" on Google Patents also indicated that the patent number could not be found, which suggests there might be an issue with the patent number provided or its indexing in public databases at the time of that prior check. However, based on the full patent text provided in the prompt, which is authoritative, I can extract some information.

Since I cannot access the USPTO assignment database, I can only provide information based on the provided patent text.

NPE / troll-pattern signals

Due to my inability to access the USPTO Assignment Center and the lack of comprehensive assignment records in the provided patent text, I cannot confidently assess most of these signals.

  1. Shell-entity transfer — Unclear. Without USPTO assignment records, I cannot determine if there have been transfers to shell entities. The Google Patents entry only shows an assignment from inventors to Sanas.ai Inc.. Sanas Ai Inc. appears to be an operating company based on its description of products and services.
  2. Known asserter in the chain — Not present. The only assignee identified is Sanas Ai Inc., which is not a known NPE from public lists.
  3. Repeat correspondent across the chain — Unclear. I cannot determine this without access to USPTO assignment records which list the correspondent of record.
  4. Cascading transfers — Not present. Only one assignment event is noted, from inventors to the company.
  5. Pre-litigation transfer — Unclear. While there is litigation noted, I cannot determine if any assignment was made within 6 months of the first suit without access to the full litigation timeline and assignment records.
  6. Bankruptcy fire-sale — Not present. The legal status of Sanas Ai Inc. is "Active", and there is no indication of bankruptcy.
  7. Privateering — Unclear. There is no information in the provided patent text or search results to suggest privateering.
  8. Defensive aggregator (anti-NPE) — Not present. The patent is currently assigned to Sanas Ai Inc., not a defensive aggregator.

Verdict

Insufficient data.

The verdict is "Insufficient data" because I could not access the USPTO Assignment Center to retrieve the full assignment history, including reel/frame numbers and correspondent information. The available information from Google Patents only indicates a single assignment from the inventors to the original assignee, Sanas.ai Inc. on 2024-07-11. This limited data prevents a comprehensive analysis of NPE/troll patterns.
