Samsung and Qualcomm file trademarks for smartwatch related devices
Samsung's filing had a primary description of the device that could have been for anything while the secondary description lists wristbands, bracelets, and "watches that communicate data to personal digital assistants, smart phones, table PCs, PDA, and personal computers through internet websites and other computer and electronic communications networks..."
Meanwhile, Qualcomm has trademarked the name TOQ for a device that will be a "personal communication hub in the form of a wristwatch; portable electronic devices for transmitting and reviewing text, data, image, and audio files; hands free devices for mobile phones; battery chargers." The company, not known for producing actual finished goods for consumers, could be ready to offer chipset solutions to smartphone manufacturers and might be readying a reference device to show the likes of Samsung, LG, Google and Microsoft what Qualcomm can offer them when it comes to powering a smartwatch.
