if I used United States Patent and Trademark Office (“USPTO”) for my
game name and publish google play store then in this world no one can use my name to publish both App Store and google play or amazon store?
I found this one recently
Lion Studios has acquired in the Love Balls trademark through its continuous use in commerce, Lion Studios is also the owner of the following federal trademark application currently pending in the United States Patent and Trademark Office (“USPTO”) Lion Studios (Serial No. xxxxxxxx) for “game software” Filed October 9, 2017
above mean no one can used this name in the world to publish game to App Store.
