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

It appears that the patent number "113299973" as provided does not correspond to a valid US patent grant number in the standard 7- or 8-digit format. Attempts to retrieve the full patent text, claims, inventors, and original assignee via web search, including targeted searches on Google Patents, have been unsuccessful. Therefore, the analysis of claims and specific details of the patent's technology cannot be performed.

I will proceed to check the USPTO Patent Assignment Search for any records associated with this literal identifier.

Inventors

Information regarding the named inventors and their employer at the time of filing for US patent 113299973 could not be determined due to the inability to retrieve the patent document itself.

Original assignee

The original assignee, their product shipments, primary line of business, and current status for US patent 113299973 could not be determined due to the inability to retrieve the patent document itself.

Assignment timeline

After searching the USPTO Assignment Center using the literal patent number "113299973", no assignment records were found. The USPTO Assignment Center searches recorded patent assignment information from August 1980 to the present. This indicates that either no assignments have been recorded for this number, or it is not a valid patent number for which assignments would be recorded.

Since the patent document itself could not be retrieved, and no assignment records exist under the provided number, I cannot reconstruct an assignment timeline.
