Companies that prevail in patent lawsuits can't relax until the inevitable appeal is over -- just ask Motorola. Nintendo, however, can take a momentary break. A US Court of Appeals just upheld the company's win over IA Labs, declaring that the Wii Balance Board doesn't infringe on an IA Labs patent. While the ruling isn't all that vital when the accessory is now a rarity at best, it puts IA Labs on the hook for Nintendo's $236,000 attorney bill. It also sends a warning to other companies plotting similar legal assaults, although we'd still expect lawsuits when other patent holders are hitting paydirt.
