I just read this brief article and as a trademark attorney something popped out at me:
Age of Booty sequel
On January 11, the makers of Age of Booty filed a trademark registration for the term "Legend of Booty."
The author of the article said "it doesn't make sense that they would register such a title without some sort of plan for a game to go with it." If he were a trademark attorney he would have known that not only does it not make sense, but it's not valid.
You have 2 possible bases for filing an application to register a trademark: you are using the mark in commerce, or you intend to use the mark in commerce within the next 6 months.
A quick peek at the USPTO website shows this is a 1B intent to use application and that it's for "computer game software . . . [etc.]"
So basically Certain Affinity has just told the world "we have a computer game coming out in the next 6 months called "Legend of Booty."
