Blizzard files 'Heroes of the Storm' trademark application
On September 24, Diablo creator Blizzard Entertainment filed an application to trademark the phrase "Heroes of the Storm" with the United States Patent And Trademark Office.

It's unclear what Blizzard plans to use this trademark for, though the application specifies that the mark is for use in computer and console games, downloadable content, and games designed for mobile devices such as smartphones and tablets. More intriguingly, the application notes that the name could also be applied to "computer games that may be accessed via a global computer network," lending credence to the theory that "Heroes of the Storm" may refer to an upcoming expansion for Blizzard's hit MMORPG World of Warcraft.

Whatever this trademark application refers to is not likely to be revealed to the public any time soon. We contacted Blizzard for clarification on its plans but were met with a boilerplate "no comment" in response.
