While Amazon doesn't appear to be in any hurry to offer Bitcoin on its marketplace, it was awarded a patent that includes Bitcoin as a funding source for its cloud computing services, known as AWS. The United States Patent and Trademark Office (USPTO) granted patent 8,719,131, "Allocating financial risk and reward in a multi-tenant environment," to Amazon Technologies, Inc. The patent was originally filed on March 29th, 2012.
The patent appears to be a flexible pay-per-use cloud computing scheme that Amazon could integrate into AWS. The patent covers a broad range of uses including allowing for "anonymously spawned" frictionless pay-per-use resource allocation as well as a crowdsourcing fundraising mechanisms to provide access to these resources.
Users would get access to Amazon services without having to provide their private credentials such as credit card number and home address in part by paying for services with Bitcoin.
