theodp writes: Microsoft says it has reached a wide-ranging IP agreement with Amazon in which each company has granted the other a license to its patent portfolio. Microsoft says the agreement covers technologies in products including Amazon's Kindle — including open-source and proprietary technologies used in the e-reader — in addition to the use of Linux-based servers. Microsoft issued a news release celebrating the accord, while Amazon declined to comment. 'We are pleased to have entered into this patent license agreement with Amazon.com,' said Microsoft's deputy general counsel.. 'Microsoft's patent portfolio is the largest and strongest in the software industry, and this agreement demonstrates our mutual respect for intellectual property as well as our ability to reach pragmatic solutions to IP issues regardless of whether proprietary or open source software is involved.' A Microsoft representative declined to say which of its products are covered by the deal.
