CM HK Limited

CM HK Limited is a Hong Kong-based entity involved in patent assertion, often associated with CyWee Group Ltd. While the exact founding year and specific operational details beyond patent licensing are not publicly available, CM HK Limited appears to operate as a non-practicing entity (NPE). It is not to be confused with China Mobile Hong Kong Company Limited (CMHK), a large telecommunications operator and a wholly-owned subsidiary of China Mobile Limited.

CM HK Limited primarily asserts a patent portfolio related to motion-sensing technology for smartphones. The patents involved in litigation with Samsung include U.S. Patent Nos. 10,852,846, 11,698,687, 10,275,038, and 10,817,072.

The company's patent-litigation posture is that of an NPE asserting its portfolio. CM HK Limited has been a plaintiff in one tracked case and a defendant in one tracked case. The plaintiff case, CM HK Limited v. Samsung Electronics Co., Ltd. et al., was filed in the U.S. District Court for the Eastern District of Texas, a venue known for patent plaintiff activity. The defendant case, Samsung Electronics Co., Ltd. v. CM HK Limited, is an action before the USPTO Patent Trial and Appeal Board, typically a defensive maneuver against patent assertions.

Notably, CM HK Limited, along with CyWee Group Ltd., has engaged in patent disputes with Samsung Electronics Co., Ltd., concerning motion-sensing technology in mobile devices. Samsung previously filed a declaratory judgment of non-infringement against CM HK Limited and CyWee regarding several patents. Unified Patents characterizes CM HK Ltd. and CyWee Group Ltd. as a "NPE (Small Company)" in their litigation tracking.
