Merry Christmas! The USPTO is celebrating in a big way, with the copyright stamp making some pretty big rounds today. First up is a design patent for an iPod touch, which Cupertino filed back in August of 2011. It looks to be the fourth-gen model from 2010, especially given that the patent focuses on the very rounded edges. This iPod touch was the first version to include both front- and rear-facing cameras, and in any case, the design is miles thicker and shorter than this year’s touch. As Patently Apple points out, this document also happens to be one of the last to list Steve Jobs as an inventor.
