BBC News - Paul Allen sues tech giants over 'patent violations': "The co-founder of Microsoft, Paul Allen, is suing several high-tech giants for infringing patents held by a firm he founded in the 1990s.
The legal action against Apple, Yahoo, Facebook, Google and eBay, as well as six other firms, asserts that web technologies first developed by Interval Licensing have been infringed.
The patents are key to how e-commerce and search websites worked, it says.
Google, Facebook and eBay immediately said they would fight the accusations.
'This lawsuit against some of America's most innovative companies reflects an unfortunate trend of people trying to compete in the courtroom instead of the marketplace,' a Google spokesman said in a statement.
'Innovation - not litigation - is the way to bring to market the kinds of products and services that benefit millions of people around the world.'
A Facebook spokesman called the action 'completely without merit'."
