Assignment timeline

No assignment records were found for US patent 12370153 at the USPTO Patent Assignment Search website (https://assignmentcenter.uspto.gov/) as of 2026-05-29.

However, Google Patents lists one assignment event:

• 2024-07-12 / recorded N/A (Google Patents does not provide recording date or reel/frame for this specific event)
  • Conveyance: Assignment of Assignor's Interest
  • Assignor: DUSCI, SERGIO
  • Assignee: InfoRLife SA
  • Correspondent: Not specified in Google Patents event data.
  • Context: Transfer from individual inventor to the company that filed the patent application. This is a common practice where the inventor assigns their rights to their employer or the entity sponsoring the research.

Given the absence of records on the USPTO Assignment Center, any subsequent transfers of ownership are not publicly recorded with the USPTO. The Google Patents entry for "2024-07-12: Assigned to InfoRLife SA" likely refers to the initial assignment from the inventor to the assignee, which may or may not be formally recorded in the public assignment database by reel/frame, or may be recorded with the application as part of the initial filing. Without a reel/frame, it cannot be confirmed via the USPTO Assignment Center.

Verdict

Insufficient data.
The USPTO Assignment Center shows no recorded assignments for US12370153. While Google Patents indicates an initial assignment from the inventor to Inforlife SA, this is a standard practice and does not signal NPE activity. Without a chain of recorded assignments, there is insufficient data to identify any NPE or patent-troll patterns. Verification can be performed by searching the USPTO Assignment Center for US12370153 (https://assignmentcenter.uspto.gov/patent/index.html?pno=US12370153).
