A group of lawsuits filed on Monday by Priceline founder Walker Digital take aim at Apple, Google, Microsoft, Amazon and more than 100 other companies for infringing on key parts of its patent portfolio.
The 15 lawsuits, filed in US District Court of Delaware, say these companies are infringing Walker Digital-owned patents covering things like e-commerce, private social-networking communications, online auctions and a driving-directions tool with visual cues.
"A number of great companies can trace their genesis to technology that was first developed at Walker Digital in the mid-to-late 1990s," Walker Digital's chairman Jay Walker said in a statement. "We are proud of our inventions and the number of innovative businesses and activities founded on these inventions. These businesses have not only changed the way people around the world live, work, travel and interact socially and commercially, but also have given rise to numerous American jobs."
