Nokia filed a patent infringement lawsuit against Apple today, claiming the iPhone maker is unfairly earning millions off technology Nokia developed. The patents, ten in all, cover 2G and 3G wireless connections and WiFi. "The basic principle in the mobile industry is that those companies who contribute in technology development to establish standards create intellectual property, which others then need to compensate for," a Nokia executive said. Apple is already paying royalties to Nokia, but one analyst says the suit appears be an attempt to squeeze Apple for even higher payments. Since the iPhone hit the market, Nokia's market share has dropped 25 percentage points.
