Redmond WA (AP) Microsoft (MSFT) has announced a $54 million lawsuit against Tomagotchi maker, Bandai. Microsoft is claiming that the Tomagotchi, the Japanese electronic pet that's all the rage with the kids, is an infringment of its intellectual property. "Software that needs constant, even hourly attention, or else it dies? Sounds like Windows to me", stated MSFT spokesman Eric Longford. "This is clearly an infringment on our technology." Bandai refused to comment on the suit.
