Touch feedback technology company Immersion Corp said it filed a complaint in the US District Court for the Northern District of California against Fitbit, Inc. alleging infringement of three Immersion US patents.
Immersion said it also filed complaints against Fitbit and its Shanghai-based distributor in China, Runtong International Trade Co., Ltd. in the Shanghai Intellectual Property Court, alleging infringement of three Immersion Chinese patents.
The complaints allege that certain Fitbit wearable devices including the Fitbit Flex, Fitbit Flex 2, Fitbit Alta, Fitbit Alta HR, Fitbit Charge, Fitbit Charge 2, Fitbit Charge HR, Fitbit Blaze, and Fitbit Surge infringe Immersion patents “covering haptic feedback devices, systems and methods.”
Immersion CEO Victor Viegas said: “Since 1993, Immersion has been a leading innovator in the field of haptic technology, leveraging our culture of innovation and market-leading haptic know-how.
“Our valuable patents in the U.S. and China help us protect our longstanding investment in research and development in this exciting field.
“We are disappointed that Fitbit rejected our numerous attempts to negotiate a reasonable license for Fitbit’s products, but it is imperative that we protect our intellectual property both within the U.S. and through the distribution chain in China.”
Immersion said the complaints seek orders requiring Fitbit and its Chinese distributor Runtong “to immediately and permanently stop manufacturing, using, selling, offering for sale, or importing infringing Fitbit devices in both the U.S. and China; as well as damages to compensate Immersion for the harm the infringement has inflicted.”
