The Last Guardian trademark fell away last month due to negligence on some employee's part, but it was revived before any damage could be caused. It would appear that Sony wants to stay ahead of the game this time around, as they've filed for a third, protective trademark that will assure The Last Guardian's name is safe from plagiarism.
Here's the confusing wall of text that indicates as much:

The Last Guardian's development was abandoned for a short time, revived after fans' outcry. The game, originally slated for release exclusively on Sony's Playstation 3, was oneof the most hyped games of last generation.
We're hoping to hear more about The Last Guardian at E3 in June.
