Connected fitness remains a hot issue in terms of intellectual property rights. Dish Network Corp. and its Sling TV division are suing Peloton Interactive, Lululemon Athletica and Icon Health & Fitness for allegedly infringing five patents for technology that improves the quality of video content on the internet through multi-bitrate and adaptive-rate content streaming. In the lawsuits, which were filed on April 13 in federal courts in East Texas and Delaware, Dish says that all three fitness companies used its patented technology, developed by Move Networks, which “allows Internet users to stream content from across the world in real time at the highest possible quality.” Dish acquired Move Networks in 2010. The patents that are cited in the suits involve ways of improving online video quality especially when fast-forwarding, rewinding and browsing on multiple streams without interruption. Sling uses the technology in an offering for live TV channels streamed over the internet for a monthly subscription fee. According to Dish, the Sling TV software can “replicate the streaming-while-exercising experience.” Dish wants the courts to block further unauthorized use of the technology by the three fitness companies in the distribution of live and on-demand video content on their platforms, including Lululemon’s recently acquired Mirror. The plaintiff is also seeking damages from sales of streaming services that it says infringe its patents, including cash compensation for lost sales. Sling, which specializes in online video streaming, accounts for about 22 percent of Dish’s video subscriber base, according to Bloomberg analysts.
