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

Manuel Ignacio Tijerino is the sole inventor. The patent does not specify his employer at the time of filing; however, the original and current assignee is listed as "Individual", suggesting he was self-employed or acting independently at the time of filing.

Original assignee

The original assignee is listed as "Individual" (Manuel Ignacio Tijerino). It is unclear from the patent text whether the inventor, as an individual, shipped a product embodying the claims directly. The patent describes a system to allow artists to upload media to a server and have it available on internet jukeboxes, implying a service rather than a physical product. His primary line of business, based on the patent, appears to be related to providing this media distribution and monetization platform for artists. His current status (operating, acquired, dissolved, in bankruptcy) is not determinable from the patent document itself.
