Apple is in the middle of a month-long patent trial with Samsung, and the iPhone maker is taking time out — on Earth Day no less — to dig at its competition. In newspaper adverts that accompany a revamped environmental site, Apple takes clear aim at Samsung while highlighting its green-themed energy campaign. There are some ideas we want every company to copy, reads the headline of the ad, a clear reference to Apples aggressive shift to renewable energy. While Apple is trying to convince a jury of eight that Samsung has copied features from iPhones, iPods, and iPads, Samsung Electronics is marking its 45th anniversary this week by opening its own Innovation Museum in South Korea to highlight historical inventions from its competitors.
