Comcast has filed a new trademark for DOWNLOAD2GO ahead of what appears to be a new mobile video offering by the cable giant. According to Fierce Cable, the patent application covers "computer application software for mobile devices, mobile phones, smart phones, cell phones, tablet computers, handheld computers, computers and/or other portable computer devices, namely, software for downloading and viewing audio-video content on such a device." Comcast's co-marketing deal with Verizon so far only covers giving bundle users prepaid gift cards, though both companies have promised they're working on tech that allows users to share cable content between their fixed line and wireless services. Many cable operators are also planning on services that allow place-shifting of content from DVRs to local devices.
