Microsoft has signed a patent cross-license agreement with Amazon.com , providing each company with access to the other’s patent portfolio.

The agreement covers a broad range of products and technology, including coverage for Amazon’s popular e-reading device, Kindle, which employs both open source and Amazon’s proprietary software components, and Amazon’s use of Linux-based servers.
Although specific terms of the agreement are confidential, Microsoft indicates that Amazon.com will pay Microsoft an undisclosed amount of money under the agreement.
“We are pleased to have entered into this patent license agreement with Amazon.com,” says Horacio Gutierrez, corporate vice-president and deputy general counsel for Intellectual Property and Licensing at Microsoft. “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.”
