Shenzhen City Sanhu Technology Co., Ltd.

Shenzhen City Sanhu Technology Co., Ltd. is a Chinese consumer products company headquartered in Shenzhen, China. The company's primary focus, as indicated by its patent assertion, appears to be in consumer accessories. Its ownership status and size (employee count or revenue) are not publicly disclosed.

The company's product involvement, based on its patent litigation, centers on a "hat holder product." Specifically, the patent US10413047B2 covers a hat holder device designed for portable hat carrying and storage technology.

Shenzhen City Sanhu Technology Co., Ltd. exhibits a patent assertion posture, having appeared as a plaintiff in its sole tracked patent litigation case and never as a defendant. This indicates that the company actively asserts its intellectual property rights. The single case was filed in the California Central District Court, though it was initially transferred from the Eastern District of New York.

The company's most notable tracked case is Shenzhen City Sanhu Technology Co., Ltd. v. Lindsay Albanese et al., filed on November 1, 2023. In this litigation, Shenzhen City Sanhu Technology Co., Ltd. accused Lindsay Albanese and Hats On, LLC (doing business as TopTote) of infringing US10413047B2, a patent related to a hat holder product. The plaintiff voluntarily dismissed the action without prejudice on June 6, 2024, leaving open the possibility of future proceedings.
