Patent 11806120

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.

Original assignee

The original assignee, as listed on the issued patent, is Beijing Shunyuan Kaihua Technology Co Ltd.

Beijing Shunyuan Kaihua Technology Co Ltd ("Shun Yuan") is a wholly-owned foreign enterprise incorporated with limited liability in the People's Republic of China and a subsidiary of Zepp Health Corporation (formerly Huami Corporation). Zepp Health Corporation is a global sports and wellness technology company primarily engaged in developing, manufacturing, and selling smart health wearable products under brands like Amazfit and Zepp Aura. Given this, Beijing Shunyuan Kaihua Technology Co Ltd likely ships products embodying the claims, or is a critical part of the supply chain for such products. The company is currently operating as a subsidiary of Zepp Health Corporation, which is a publicly traded entity (NYSE: ZEPP).

Assignment timeline

A search of the USPTO Patent Assignment Search database for US patent 11,806,120 reveals no recorded assignments for this patent. This indicates that the ownership has remained with the original assignee, Beijing Shunyuan Kaihua Technology Co Ltd, since the patent was granted. It is possible that the assignment from the inventors to Beijing Shunyuan Kaihua Technology Co Ltd occurred prior to the filing of the application (or its parent application) and was therefore recorded at the application level rather than as a post-issuance assignment, or it was never separately recorded for this particular continuation patent.

Verdict

Insufficient data.
While the current assignee, Beijing Shunyuan Kaihua Technology Co Ltd, is part of an operating company (Zepp Health Corporation) that manufactures relevant products, the absence of any assignment records for this specific patent (US11806120) in the USPTO Assignment Center means there is insufficient information to fully analyze the ownership chain or definitively identify NPE/troll patterns. The original assignment from the inventors to the assignee likely occurred at the time of the initial application filing and is not explicitly available for this continuation patent.
