Given how ho-hum Apple's WWDC was, they may as well go the lawsuit route. Maybe there will be a market in the judicary for a phone with an amazing "do not disturb" feature.
Multi-source searching? Really? I don't like seeing companies fight with trivial patents, but in times like these I wish Google would just use whatever patents it had available from their search technology or whatever, and just shoot them all at Apple, and actually turn aggressive against them. Maybe this way Apple will finally learn to ease up with these continuous, and seemingly expanding patent lawsuits.
