The USPTO recently released a beta test version of the official website. The test version is found here. From USPTO.gov:
The USPTO is pleased to announce the beta test release of its new Web site. The new site has been redesigned to improve the look and feel, as well as to enhance the user experience with improved navigation. The USPTO’s goal is to make the Web site technologically up-to-date, user-friendly, and responsive to customer feedback. Please keep in mind this is the initial release of the beta site and the content is not currently up to date. The Office of the Chief Information Officer (OCIO) is still in the process of migrating and reorganizing the content. We invite you to explore the beta web site and give us your constructive feedback. Your comments and suggestions will help us to build a site that better serves your needs. Please submit your feedback either through moderator, or send your comments to email@example.com.
