The lawsuits are raging all across the tech world. Oracle sues Google, Yahoo sues Facebook, they counter-sue. Others threaten, others buy more patents and the circle goes round and round.
Don't be fooled by the lawsuits between these tech titans though. The real cost that the patent mafia extracts from the tech world is on the smaller companies who can't afford to battle the Apples and Microsofts of the world. Their choices are far simpler. They can abandon their innovations or they can choose to pay and allow the Mafiosos to wet their beaks. Also, don't be fooled about who the real losers are here. The the real losers are you and me. We lose out on being able to leverage innovative new ideas and technologies that come to market or have to pay more for them so that the the mafia can wet its beak.
This system of software patents has been called out by many. While companies are certainly entitled to the fruits of their inventions, many of these patent rackets are based on patents improperly issued, improperly enforced or improperly applied.
