Title: Resolution independent display of internet content

Assignee: SoftView LLC

Inventors: Gary B. Rohrabaugh, Scott A. Sherman

Filing Date: April 15, 2007

Issue Date: November 30, 2010

Abstract: Apparatus, methods, and software are described for creating resolution-independent display of Internet (Web) content, allowing Web pages to be scaled (zoomed) and panned for improved viewing and/or to fit any resolution or screen size. One aspect involves novel client-side processing of markup language-based Web content, where a rendering engine interprets original page layout information. This page layout information is then scaled and used to enable rapid rendering, zooming, and panning of the Web content. Other aspects include the generation of display lists for enhanced rendering speed and the use of generated and scaled bounding boxes to arrange text and/or images on scaled Web content, thereby facilitating Web page browsing with zooming and panning.

Plain-Language Overview of Independent Claims:

• Claim 1 (Method): This claim describes a method for providing a display of web content that is independent of the client device's resolution. The method involves receiving web content from a network, parsing this content to extract page layout information, and then translating this layout information into a scalable vector representation (e.g., Simple Vector Format - SVF). Subsequently, a display list is created that includes vectors and bounding boxes for the objects within the content. Finally, the content is rendered on the client device's display at a user-selected scale (zoom) and offset (pan).
• Claim 16 (System): This claim outlines a system designed for resolution-independent display of content. The system includes a server-side content translator that is configured to receive web content, parse it for page layout information, and translate this information into a scalable vector representation (like SVF). This translation process generates a display list containing vectors and bounding boxes for the content's objects. The system also comprises a client-side viewer configured to receive the scalable vector content, build a display list, and render the content on a display based on user-selected scale and pan values.
• Claim 21 (Computer Readable Storage Medium): This claim covers a computer-readable storage medium that contains instructions. When these instructions are executed by a processor, they perform the method detailed in Claim 1. In essence, it claims the software implementation that allows a processor to achieve the resolution-independent display of web content through the described translation, display list generation, and rendering steps.

Legal Status and Litigation:

The patent US7844889 expired on August 3, 2023. Despite its expiration, there is ongoing litigation:

• A PTAB (Patent Trial and Appeal Board) case, IPR2026-00284, was filed and is currently pending in 2026. The petitioner is Unified Patents.
• A US case (2:25-cv-00246) was filed in the Texas Eastern District Court on February 28, 2025, by SoftView, LLC against [[[Samsung Electronics Co.](/litigations/by-defendant/Samsung%20Electronics%20Co.), Ltd.](/litigations/by-plaintiff/Samsung%20Electronics%20Co.%2C%20Ltd.) et al.](/litigations/by-plaintiff/Samsung%20Electronics%20Co.%2C%20Ltd.%20et%20al.) Patent 7844889 is one of the asserted patents in this case.
• The patent family has also been involved in a first worldwide family litigation.

While no new direct CAFC 2026 docket specifically for US7844889 was found in a targeted search, the existing records from Google Patents and other legal databases confirm the ongoing PTAB and District Court litigation involving this patent.
