Coolpad has announced that its subsidiary, Yulong Computer Telecommunication Scientific (Shenzhen) has filed a lawsuit against Xiaomi Telecom Technology, Xiaomi Technology and Xiaomi Factory in a court in Jiangsu province for using its patents without authorization.
Yulong demanded that the Xiaomi companies should immediately stop production or offering for sale and current sale of some of the smartphone models, including the Xiaomi 6, Xiaomi Max2, Xiaomi Note3, Xiaomi 5X, Redmi Note4X and Mi MIX2.
Yulong had filed a similar legal case against Xiaomi in a Shenzhen court in January 2018 as well. The patents involved in this lawsuit are systematic interactions or UI type patents. They all involve basic communication, display and interactive functions of mobile phones, and are difficult to circumvented or replaced.
“It is because the IP (intellectual property) protection environment in China has improved, Coolpad launched the lawsuit in January this year,” said Coolpad’s global chief patent officer Nancy Zhang.
Coolpad has alleged that Xiaomi violated its patented multi-SIM card design and other technology related to user interface.
Jiang Chao, CEO, Coolpad said, “If cumulative achievements of thousands of R&D engineers’ working from day to night for 25 years, are arbitrarily plagiarized and not pursued, we should reflect on our tolerance and this will ultimately harm innovation in the entire nation and the future generations.”
Syed Tajuddin, CEO, Coolpad India said, “We already have 13,000+ patent applications globally and out of them 2,000 has been already authorized, we are looking forward do whatever it needs to make sure they are not infringed. We have been very cooperative right from start in the cases but it didn’t worked and we have to file law suites to legally stop from competing brands to use the technology that has been patented after relentless hard work from our R&D teams.”
