Assignee: EXPRESS MOBILE Inc.
Inventor: Steven H. Rempell
Filing Date: December 2, 1999

Abstract:
A method and apparatus for designing and building a web page. The apparatus includes a browser-based build engine including build tools and a user interface. The build tools are operable to construct a single run time file and an associated database that describe, and when executed, produce the web page. The user interface includes a build frame and a panel. The build frame is operable to receive user input and present a WYSIWIG representation of the web page. The panel includes one or more menus for controlling the form of content to be placed on the web page.
Plain-Language Overview of Independent Claims
U.S. Patent 6,546,397 has one independent claim.
Claim 1: This claim describes a method for a user to build a web page using a web browser. The core of the invention is a "build tool" that operates within the browser. This tool has two main parts: a "build engine" and a "user interface." The user interface shows the user a "what you see is what you get" (WYSIWYG) view of the web page as it is being built. The user can add and edit content on the page, and the build engine takes these inputs and creates two key outputs: a single "run time file" and an associated database. When this run time file is executed by a visitor's web browser, it uses the information in the database to dynamically generate and display the final web page.
Essentially, the patent describes an in-browser website builder that packages the entire website's structure, content, and functionality into a compact set of files for efficient delivery and rendering.
