Shenzhen Kelaisiman Trading Co., Ltd. is a Chinese entity known primarily for its patent litigation activities in the United States. Its specific headquarters, founding year, employee count, or revenue figures are not publicly disclosed in verifiable sources. It is not listed as a public company, and its private ownership status, or whether it operates as a subsidiary, remains unconfirmed. Efforts to identify a dedicated corporate website or detailed product catalog for Shenzhen Kelaisiman Trading Co., Ltd. have not yielded conclusive results.
While a direct product portfolio is not publicly detailed, Shenzhen Kelaisiman Trading Co., Ltd. is the lead plaintiff in a patent infringement lawsuit targeting the consumer health technology sector. The patents asserted cover technology related to massage guns and smart goggles. The company's role as the leader of a group of seven Chinese consumer health technology companies in this litigation suggests its involvement, either directly or indirectly, with the manufacturing or intellectual property aspects of these types of products.
Shenzhen Kelaisiman Trading Co., Ltd. exhibits a plaintiff-side patent litigation posture, having appeared as a plaintiff in its sole tracked case and as a defendant in none. The company, along with other Chinese manufacturers, filed a patent infringement suit against Hyper Ice, Inc. and Hyperice IP Subco, LLC in the U.S. District Court for the Central District of California. This action asserts four U.S. patents (US12097161B2, US11938082B1, US12036174B1, and US11857482B1) covering massage gun technology and smart goggles.
The most prominent case involving Shenzhen Kelaisiman Trading Co., Ltd. is Shenzhen Kelaisiman Trading Co., Ltd. et al. v. Hyper Ice, Inc. et al. (Case No. 8:24-cv-01472), filed on July 3, 2024, in the U.S. District Court for the Central District of California. The case was subsequently stayed on July 25, 2025, pending the resolution of two Post-Grant Reviews (PGRs) by the U.S. Patent and Trademark Office concerning two of the asserted patents (US11857482 and US11938082). This procedural pause shifts the validity dispute to the USPTO, with the outcome of the PGRs potentially impacting the continuation of the district court litigation.
