Defendant
1 case as defendant.
CyWee Group, Ltd., often referred to by its operating brand CyweeMotion, is a technology company with its founding team originating from Taiwan's Industrial Technology Research Institute in 2003. The Taiwan company was founded in 2014, and its headquarters were transferred to Shenzhen in 2021 to better approach target markets. CyweeMotion maintains professional technology teams in both Taiwan and Shenzhen. The company is privately held and has received funding from entities such as CMB International and Realtek Semiconductor.
CyweeMotion specializes in AI motion-sensing algorithms and advanced sensor fusion technology. Their solutions are integrated into over 150 million consumer electronics devices. Key product lines and service offerings include 9-axis sensor fusion algorithms for smartphones, health and activity monitoring for smart wearables, 3D head tracking for spatial audio in hearables, and 6DoF (six degrees of freedom) and SLAM (simultaneous localization and mapping) solutions for AR/VR and IoT applications. The company's clients include major brands such as Xiaomi, Honor, Nothing, Edifier, Baseus, OPPO, and Keep.
Based on the provided authoritative case data, CyWee Group, Ltd. has been involved in one tracked U.S. patent litigation as a defendant. This case, Samsung Electronics Co., Ltd. et al. v. CM HK, Ltd. et al., was filed in the U.S. District Court for the Northern District of California on September 18, 2024. However, external analysis consistently characterizes CyWee Group, Ltd. as a patent assertion entity (PAE) or patent holding and licensing entity that has actively asserted patents as a plaintiff in numerous litigations.
External records indicate that CyWee Group, Ltd. has previously asserted patents covering 3D pointing device motion compensation and motion sensing technology, including U.S. Patents US8441438B2 and US8552978B2. These patents were subject to inter partes review (IPR) proceedings by third parties, with the U.S. Patent and Trademark Office finding the asserted claims unpatentable. These invalidity rulings were subsequently affirmed by the U.S. Court of Appeals for the Federal Circuit in cases such as CyWee Group Ltd. v. Google LLC (2023) and CyWee Group Ltd. v. ZTE (USA), Inc. (2024), effectively ending CyWee's enforcement campaigns on these particular assets.
In this action, Samsung seeks a declaratory judgment of non-infringement of the '846 patent. A motion to dismiss for lack of personal jurisdiction was granted, but the court is allowing Samsung to conduct jurisdictional discovery.
