Sony Ericsson has filed a trademark for Xperia Ion, a name that could eventually find its way to the recently uncovered LT28at smartphone.  The trademark, which was filed on December 13th, is associated with a serial number of 85493863.

The Sony Ericsson LT28at looks to be the manufacturer’s flagship device of 2012 with a 4.55-inch 720p display and 13MP camera. The Xperia Ion name has not been definitively linked with the LT28at, but it is safe to assume we might see a device appear under the branding at CES 2012. Sony is set to kick off their week of gadgety goodness on Monday, January 9th with a special presentation for show attendees.
