HQDTech USA LLC

HQDTech USA LLC is a privately held company that operates as a distributor of electronic cigarettes and vaping products in the United States. While its contact address is in the Miami, Florida area, its parent company is Shenzhen Hanqingda Technology Co., Ltd., a China-based manufacturer founded in 2014. Publicly available information on the specific revenue and employee count for the US entity is not available, though its global parent is a large enterprise with what it describes as thousands of employees. In 2020, the U.S. Food and Drug Administration (FDA) issued a warning letter to the company for offering products for sale in the U.S. without the required marketing authorization.

The company distributes disposable electronic nicotine delivery systems (ENDS), commonly known as vapes. HQDTech USA is described as a major U.S. distributor for the "HQD" brand of these products. Its product lines include a wide variety of flavored, disposable vaping devices such as the HQD Cuvie, Cuvie Plus, Cuvie Bar, and Rosy models, which are designed for one-time use. These products are sold online and through wholesale channels.

Based on its litigation history, HQDTech USA LLC is an operating company that has defended itself against patent infringement claims. The company has been a defendant in one tracked case and has not been a plaintiff, a posture typical of a product company being targeted for its technology rather than an entity asserting patents. The lawsuit was filed in the Southern District of Florida, where the company is located.

The single tracked case is VPR Brands, LP v. HQDTech USA LLC et al., filed in May 2021. The lawsuit alleged that HQD's auto-draw, button-less vape products infringed on a VPR Brands patent covering e-cigarette technology that uses an electric airflow sensor. In December 2021, VPR Brands announced the case had been settled, with HQDTech USA and a co-defendant agreeing to pay a sum greater than $275,000 to resolve the infringement claims.
