Coolpad, a global leader in smartphone manufacturing and integrated wireless data solutions, has announced that its unit has sued three group firms of Xiaomi for several patent Infringements. Coolpad said in a statement that its subsidiary, Yulong Computer Telecommunication Scientific (Shenzhen) Co. Limited has filed a lawsuit against Xiaomi Telecom Technology Co, Xiaomi Technology Co and Xiaomi Factory Co, 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," Coolpad's global chief patent officer Nancy Zhang told a press conference on Friday. Coolpad has alleged that Xiaomi violated its patented multi-SIM card design and other technology related to user interface. It demanded that Xiaomi compensate it for losses due to the alleged infringement.

“On 12th January this year, Yulong Computer Communication Technology (Shenzhen) Co., Ltd., submitted a lawsuit request to Shenzhen Intermediate People’s Court and was accepted on January 25, 2018. “The Global Chief Intellectual Property Officer of Coolpad Group, Nancy Zhang, said, ”Since 2014, Coolpad has repeatedly sent warning letters to Xiaomi, stating that the mobile phone it sold was suspected of infringing on Coolpad’s patent rights and proposed friendly negotiation, but did not receive a response. In desperation, Coolpad could only seek redress through legal channels."

Coolpad Group CEO Mr. Jiang Chao 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, “It’s very important to safe gaurd your inventions and make sure no one use them for any commercial purpose without permission. As we already have 13,000+ patent applications globally and out of them 2000 has been already authorized, we are looking forward do whatever it needs to make sure they are not infringed. We have 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. We are still working in a very cooperative manner to workout best possible solutions to resolve this case with Xioami. ”

Coolpad hopes that Xiaomi will stop patent infringement and actively cooperate with Coolpad to promote industrial progress. Litigation is a legal remedy for resolving intellectual property disputes. Coolpad is looking forward to working with Xiaomi to find a better solution, strengthen intellectual property protection and create a good business environment.
