Patent 12250452

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

  • Ishay Sivan: No employer explicitly stated in the patent document at the time of filing. The original assignee is Snapaid Ltd.

Original assignee

The original assignee named on the issued patent US12250452 is Snapaid Ltd.

Based on the provided patent text, it is unclear whether Snapaid Ltd. shipped a product embodying the claims. The patent generally describes a "device image acquisition system" such as a "smartphone," suggesting the technology could be integrated into consumer electronics. However, there's no direct evidence of Snapaid Ltd. itself manufacturing or selling such devices.

Their primary line of business, as inferred from the patent, appears to be related to image processing and analysis, specifically real-time assessment of picture quality for camera systems.

The current status of Snapaid Ltd. is "Active" according to the legal status information on Google Patents.

Assignment timeline

To reconstruct the full assignment record for US patent 12250452, I need to access the USPTO Assignment Center. Since I cannot directly interact with web forms or conduct live searches on the USPTO Assignment Center, I must rely on the provided Google Patents information and what is explicitly stated in the patent text.

The Google Patents page for US12250452 mentions:

  • 2023-04-26: Application filed by Snapaid Ltd.
  • 2023-04-26: Assigned to SNAPAID LTD. ASSIGNMENT OF ASSIGNORS INTEREST (SEE DOCUMENT FOR DETAILS). Assignors: SIVAN, ISHAY, MR.

Based on this information, the initial assignment is from the inventor to the original assignee. Without direct access to the USPTO Assignment Center to search by patent number, I cannot retrieve the full, detailed assignment chain including reel/frame numbers, correspondent information, and conveyance types for any subsequent transfers.

Therefore, the assignment timeline is limited to what is explicitly available:

  • 2023-04-26 (executed) / recorded 2023-04-26 (assumed, as this is the filing date and assignment date) — Reel Not Available/Not Available
    • Conveyance: Assignment of Assignor's Interest
    • Assignor: Ishay Sivan
    • Assignee: Snapaid Ltd.
    • Correspondent: Not available in the provided text.
    • Context: Original assignment from inventor to founding company.

If the USPTO Assignment Center has no further records for this patent beyond what is indicated on Google Patents, then Snapaid Ltd. remains the current owner.

NPE / troll-pattern signals

  1. Shell-entity transfer — Unclear. The only recorded transfer is from the inventor to Snapaid Ltd. Without further information about Snapaid Ltd.'s operations or subsequent transfers, it's unclear if this patent was transferred to a shell entity.
  2. Known asserter in the chain — Not present. The only listed assignee is Snapaid Ltd., which is not a known asserter on public NPE lists.
  3. Repeat correspondent across the chain — Unclear. Correspondent information is not available in the provided data.
  4. Cascading transfers — Not present. Only one assignment is explicitly mentioned.
  5. Pre-litigation transfer — Unclear. While there is litigation mentioned in the previous section (US case filed in Texas Eastern District Court, PTAB case), the specific filing dates for those cases are in 2025. The only recorded assignment is from 2023, which is more than 6 months prior. Without exact dates for the litigation filings and any further assignments, it's unclear.
  6. Bankruptcy fire-sale — Not present. No information suggests Snapaid Ltd. has filed for bankruptcy.
  7. Privateering — Unclear. No information suggests privateering.
  8. Defensive aggregator (anti-NPE) — Not present. The chain does not terminate at a defensive aggregator.

Verdict

Insufficient data. Only the initial assignment from the inventor to the original assignee (Snapaid Ltd.) is explicitly available. Without access to the USPTO Assignment Center records for US12250452, it's impossible to determine if any subsequent transfers occurred, what their nature was, or to identify correspondent details that might indicate NPE activity. The available information does not provide sufficient evidence to confidently classify this patent's ownership chain as an NPE, operating-company assertion, or defensive.

For verification, one would need to search the USPTO Assignment Center directly for patent number 12250452 at https://assignmentcenter.uspto.gov/.
