Having prevailed on two previous charges, TiVo aims to take a bite out of Comcast once again.
While Rovi has proven amply determined to make Comcast pay license fees for the technology it uses in its video system, a source close to the cable company told FierceCable the operator has developed most of the tech used in its X1 operating system itself.
Rovi Corporation, a TiVo company, and related Rovi affiliates have filed new patent infringement lawsuits against Comcast Corporation in the US District Court for the Central District of California and the U.S. District Court for the District of MA.
The ITC previously ruled that Comcast had infringed two seperate Rovi patents and barred importation of infringing X1 boxes. The technologies in dispute include those for pausing and unpausing live video on various devices, resuming live streams already in progress, and voice input. Rovi, which acquired TiVo in 2016, had originally filed a suit alleging that Comcast and its suppliers infringed 14 of its patents. However, it said that Rovi plans to file an additional legal action with the US International Trade Commission in which it will seek an exclusion order preventing the X1 set-top boxes from being imported into the US. Comcast has said it will appeal the ITC decision, but in the meantime, the cable operator disabled a feature that allowed X1 customers to remotely schedule DVR recordings from mobile devices and web browsers.
Rovi Corporation, a TiVo company, and related Rovi affiliates filed the latest lawsuits in the US District Court for the Central District of California and the US District Court for the District of MA. The patents involved in the new complaints represent a very small component of Rovi's worldwide patent portfolio.
