San Francisco - The college-aged developer who created "Tris," a "Tetris" knock-off game for Apple's iPhone, is voluntarily removing the game from the App Store after Apple informed him of trademark and copyright claims it received from The Tetris Company, CNET News.com reported. "I'm a college student, and not an affluent one, and I simply do not have the time, energy, or resources to fight this battle right now," Tris developer Noah Witherspoon wrote on his blog. "I don't think this will be permanent; when I have the time and can find a good copyright lawyer, I'll be figuring out exactly what my position is and how I can make Tris available again."
