US Patent 9519729, titled "Scalable display of internet content on mobile devices," was issued to assignee SoftView LLC on December 13, 2016, from an application filed on November 8, 2010. The inventors are Gary B. Rohrabaugh and Scott A. Sherman.

Abstract:
The patent describes mobile devices configured to provide resolution-independent scalable display of Internet (Web) content, allowing web pages to be scaled (zoomed) and panned for improved viewing on smaller screens. These devices utilize software to process original Web content, such as HTML, XML, and cascade style sheets, to create scalable content. This scalable content is then used for rapid rendering, zooming, and panning of web content. The invention also incorporates display lists for faster rendering and enables context-sensitive zooms, such as tap-based zooms on columns, images, and paragraphs.

Independent Claims Overview:

• Claim 1 (Method Claim): This claim describes a method for providing scalable display of web content on a mobile device. The method involves a proxy server receiving a request from a mobile device for web content, along with an indication that the content should be in a scalable vector representation (SVF). The proxy server retrieves the web content, translates its HTML and CSS elements into SVF, and converts graphic images into a compressed bitmap format. It then sends this vectorized content and compressed bitmaps to the mobile device. Finally, the mobile device receives this data and renders the web page, allowing a user to zoom and pan the display.
• Claim 11 (System Claim): This claim outlines a system designed to provide scalable web content display for mobile devices. The system includes a mobile device capable of receiving content and displaying it with zoom and pan functionality. It also features a content translation service, which could be a proxy server, a web server, or integrated into the client device. This service is responsible for retrieving web content, translating HTML and CSS into a scalable vector representation (SVF), and converting graphic images into compressed bitmaps. The service then sends this processed content to the mobile device for display.
• Claim 18 (Non-transitory Computer-Readable Medium Claim): This claim describes a non-transitory computer-readable medium containing instructions that, when executed by a processor, cause the processor to perform a method for translating web content. This method involves parsing HTML and CSS of a web page to generate a scalable vector representation of the layout. It also includes generating a compressed bitmap representation of graphic images from the web page. Finally, the method involves streaming both the scalable vector representation and the compressed bitmap representation of the web page to a client.
