In a bout of “not so excellent news,” it seems that Sony has abandoned their The Last Guardian trademark:
According to the USPTO, it was “abandoned because no Statement of Use or Extension Request timely filed after Notice of Allowance was issued.” The last “Extension of Time to File SOU” was filed by Sony on July 2, 2014, and it was the third of five such files.
Such news can mean one of three things: either the entire project was cancelled and Sony is now abandoning the trademark for it, or the project is still ongoing but Sony has simply chosen to change the name.
It’s also possible that the publisher simply forgot to file a new extension request. It most certainly wouldn’t be the first time it happens in this industry.
I suppose we’ll see which of the three theories are actually correct in time.
