Apple's Case Against Samsung

On Apr. 15, Apple (AAPL) sued Samsung Electronics, stating that the company's Galaxy phones and tablet computers infringe on patents and trademarks for the iPhone and iPad. Samsung denies the claims and says it will "respond actively" to the lawsuit. Apple says Samsung copied these features:

1. Patents related to the user interface, including selecting, scrolling, pinching, and zooming

2. Design patents for the look and shape of the outer housing

3. Trademarked onscreen icons such as the sunflower for photo app
