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.

Assignment history

Inventors

Allen King (Employer at time of filing: Not explicitly stated in the patent text or available information. The patent lists the assignee as "Individual".)

Original assignee

The entity named on the issued patent is "Individual." This typically refers to the inventor, Allen King, directly holding the patent rights at the time of issuance. It is not determinable from the patent text whether "Individual" (Allen King) shipped a product embodying the claims. The primary line of business for an "Individual" holding a patent is not generally applicable in the same way as for a corporation. Their current status is assumed to be operating as an individual unless an assignment record indicates otherwise.

Assignment timeline

I have searched the USPTO Assignment Center for US patent 7490263. As of May 29, 2026, there are no recorded assignments for US Patent 7490263 on the USPTO Assignment Center. This indicates that the ownership of the patent remains with the original assignee, "Individual" (Allen King), as listed on the patent document.

Verdict

Insufficient data.
There are no recorded assignments for US Patent 7490263 on the USPTO Assignment Center, beyond the original issuance to the individual inventor, Allen King. Without any transfer records, it is not possible to assess NPE/troll patterns or any other ownership changes.
