Amazon wins patent for ordering forms

Amazon.com on Tuesday received a patent for new features on its ordering forms. In its latest patent, the online retailing giant outlined a method for expanding portions of the ordering form, then collapsing that portion of the form and removing the data fields. The content for that particular section of the form would then be displayed again.

The patent, filed in September 1997 with the U.S. Patent and Trademark Office, also described a method for editing content on the order form and redisplaying the information in the section after the changes have been made, according to a copy of the patent.
