Speedus, a money-losing holding company that runs two fast-food restaurants and co-owns a medical technology company, said on Friday that it filed a patent-infringement lawsuit against No. 2 U.S. mobile carrier Verizon Wireless. Verizon Wireless spokeswoman Nancy Tarka declined comment, saying her company has not received a copy of the lawsuit. Verizon Wireless is owned by Verizon Communications and Vodafone Group. The suit involves a patent related to the transmission of television programs to wireless devices and a patent related to simultaneous transmission of analog and digital signals within the same bandwidth, Speedus said in a statement.
