InterDigital Files Patent Infringement Actions Against Xiaomi in India


Actions Brought Subsequent to Years of Negotiation

WILMINGTON, Del., July 30, 2020 (GLOBE NEWSWIRE) — InterDigital, Inc. (NASDAQ: IDCC), a mobile and video technology research and development company, has filed two patent infringement actions in India against Xiaomi. One complaint involves infringement of five of InterDigital’s cellular 3G and 4G Indian patents and the other complaint involves infringement of three of InterDigital’s H.265/HEVC Indian patents. The claims were filed after years of negotiations and after InterDigital has made clear that it is willing to resolve the terms of a FRAND license through binding arbitration. 

The patents asserted in the cellular action draw from InterDigital’s significant contributions over the years to 3G and 4G LTE cellular standards, reflected in the company’s portfolio of more than 32,000 patents and applications worldwide. InterDigital has invested more than two decades of R&D effort in developing 3G, 4G and 5G technologies and is consistently recognized among the top innovators and owners of patents relevant to cellular wireless technologies. The patents asserted in the H.265/HEVC action reflect the world-class R&D of the company’s Research and Innovation Unit in video coding technologies, which was integrated into InterDigital’s research team after being acquired from Technicolor in 2019. 

“Wireless and video standards play the important role of eliminating barriers to entry, enabling new companies – like Xiaomi – to enter the market and have success despite having made no investment in previous wireless research activities. Advanced research drives key wireless and video standards, and fair licenses with companies that make use of those technologies enable companies like InterDigital to reinvest in still more research, benefiting all users and the industry at large. We’re hopeful that this record of research and licensing success, coupled with this claim in the Delhi High Court, will result in a fair license, and that Xiaomi will join Samsung, Apple, Huawei and many others as customers of InterDigital,” said William J. Merritt, President and CEO.

The claims were filed by InterDigital in the Delhi High Court, in New Delhi, India. In the proceedings, InterDigital is seeking compensatory and punitive damages for Xiaomi’s infringement of the asserted patents. The company is further seeking, among other remedies, injunctive relief to prevent further infringement of the litigated patents in India, unless Xiaomi elects to take a license on terms determined to be FRAND by the court.

The Indian patents asserted in the cellular action are:

  • No. 262910 – Relates to an enhancement to 3G known as High Speed Uplink Packet Access (HSUPA). The patented invention increases efficiency of bandwidth usage during HSUPA transmission by ensuring that mobile phones utilize resources allocated to them for HSUPA transmission in an efficient manner.
  • No. 295912 – Enhances utilization of cellular resources for applications (such as VoIP) which require persistent allocations of uplink resources. In particular, it enables minimization of the overhead signaling needed to modify allocations during periods of inactivity or when the persistent allocations are insufficient.
  • No. 298719 – Supports the use of multiple antennae transmissions in 4G (LTE by enabling the use of flexible levels of error protection for reporting by the handset, increasing the reliability of the signaling.
  • No. 313036 – Allows mobile phone users quick and efficient access to 4G (LTE) networks. One of the main technological challenges of developing LTE networks was efficient bandwidth usage for various traffic types such as VoIP, FTP and HTTP. This patent relates to inventions for quickly and efficiently requesting shared uplink resources — for example, reducing lag when requesting a webpage on a smartphone on LTE networks.
  • No. 320182 – Reduces power consumption by selectively switching the mobile phone’s LTE modem into a sleep mode. The patent enables switching between the sleep and awake modes based on rules within the mobile phone thereby minimizing signaling from the base station.

 The Indian patents asserted in the H.265/HEVC action are:

  • Nos. 242248 / 299448 – The patented inventions, which stem from a common patent application, provide an enhanced video decoder, which avoids the need for storing and transmitting certain overhead data associated with the encoded pictures. For video streaming, the inventions reduce the network resources required to deliver videos while reducing the memory needed to store videos within mobile phones.
  • No. 308108 – Enhances picture quality for a decoded video by providing a series of filters, including an adaptive filter, for reducing noise which is generated during the encoding process. This invention results in visibly clearer video images.
