As discovered by Fusible, Amazon has made the unexpected move of spinning its recently launched Kindle Fire (tablet) brand into a seperate company. Found in a filing with the U.S. Patent Office, Amazon has registered patents for both the Kindle Fire and Amazon Silk under the company Seesaw LLC. Both Amazon and Seesaw have the same patent lawyer.
Now what would be the reason? As Fusible points out, Amazon will probably be able to get the necessary investments for the Kindle Fire, and any other mobile/tablet brand they plan to launch.
