Patent 11349200

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.

Verdict

Insufficient data (only the original assignment from inventors to the original assignee). The single recorded assignment is from the individual inventors to Fractus S.A., which is identified as the original assignee on the patent itself. This transfer is a standard procedural assignment from the inventors to their employer. Without further assignments, it's not possible to determine if the patent has been transferred to an NPE.
