Cable companies sue Apple-backed patent coalition
A handful of cable companies are suing a coalition of tech firms that controls the rights to more than 4,000 patents.
In a document filed with the US District Court for Delaware, Charter Communications, Suddenlink and other cable firms said that lawsuits and threats from the Rockstar coalition over patent rights it owns “have cast a cloud of uncertainty” over their operations. The cable companies’ complaints echo those of Google, which has accused Rockstar of an aggressive campaign to push its products out of the market. Apple, Microsoft and Research in Motion are part of the Rockstar coalition.
