Amazon files patent suit against DiscoveryMay 19, 2009 in Technology / Business
US online retail giant Amazon has filed a lawsuit against Discovery Communications alleging it infringed four of Amazon's e-commerce patents, The Wall Street Journal reported on Tuesday.
The newspaper said the suit alleges infringement of patents covering search engine and recommendation technology by an e-commerce site run by Discovery, an operator of cable-television networks based in Silver Spring, Maryland.
It said the suit was filed last week in US District Court in Seattle.
Amazon's suit comes after Discovery filed a patent infringement lawsuit against the Seattle, Washington-based online retail company in March over its popular electronic reader, the Kindle.
Discovery, in the suit filed in a US District Court in Delaware, claimed Amazon violated a patent it registered in November 2007, and said the Kindle infringes Discovery's intellectual property rights.
Discovery said Kindle violates its development of a digital rights management scheme -- the way Amazon protects the books it sells for the handheld product.
The Journal also reported that Amazon had filed counterclaims in connection with Discovery's suit.
