    Chinese Intellectual Property Court Rules in Favor of Edwards Limited in Patent Infringement Case Against Grand Hitek.

    CHINA | 17 January 2025 | 3 min

    The Beijing Intellectual Property Court of China has ruled that Grand Hitek’s utilization of copy iXH stators (ZL200480012522.8) and low vacuum rotors (ZL201080051166.6) constituted an infringement of Edwards Limited’s patented technologies.

    The China National Intellectual Property Administration (CNIPA) upheld the validity of the rotor patent (ZL201080051166.6) during invalidation proceedings. A decision regarding the validity of the, now-expired, stator patent (ZL200480012522.8) is still pending. 

    The infringed rotor patent protects critical components of the iXH, which Edwards recommends be replaced with newly manufactured rotors in over 90% of service operations. This ruling serves as a significant reminder to Edwards pump owners considering using third party service providers that copy iXH rotors are unlikely to adhere to the same standards established by Edwards Limited and may similarly be found to infringe upon Edwards Patents (such as ZL201080051166.6).

    Grand Hitek still have the opportunity to appeal the decision, but Edwards are confident the original judgements will be upheld.

    Edwards Limited remains committed to upholding its intellectual property (IP) rights. We respect the valid IP of our competitors, and are dedicated to actively enforcing our own IP to protect our significant spend on continually developing innovative products for our customers and to ensure job security for our employees.
