US Patent 8145995: Scalable display of internet content on mobile devices

• Title: Scalable display of internet content on mobile devices
• Assignee: SoftView LLC
• Inventors: Gary B. Rohrabaugh, Scott A. Sherman
• Filing Date: December 1, 2008
• Issue Date: March 27, 2012
• Abstract: Mobile devices are enabled to support resolution-independent scalable display of Internet (Web) content, allowing Web pages to be scaled (zoomed) and panned for improved viewing on smaller screen sizes. These mobile devices utilize software-based processing of original Web content, including HTML, XML, and cascade style sheets, to facilitate rapid rendering, zooming, and panning of Web page content. The rendered displays maintain a substantially identical layout to the original Web page, allowing users to easily navigate content and features on familiar Web pages. User input methods include tap-based context zooming, enabling users to selectively zoom in on specific objects like columns, images, and paragraphs by tapping them. Display lists may also be used to enhance rendering speed, and hardware-based programmed logic can facilitate various operations.

Plain-Language Overview of Independent Claims:

• Claim 1 (Client-side Method): This claim describes a method for a client device (like a mobile phone) to display web content that can be zoomed and panned without losing quality. The method involves the client receiving a special "scalable vector representation" of a web page and compressed images from a server. The client then organizes this content into a display list. Based on user input, such as a tap to zoom in on a specific part of the page (like a column or image), the client adjusts the content's scale and position. It then retrieves only the necessary parts of the content that will be visible, scales them (including decompressing and resizing images and text), and displays them on the screen.
• Claim 10 (Server-side System): This claim outlines a server system designed to provide web content to client devices. The server retrieves requested web pages and their associated graphics from the internet. It then translates the web page content into a scalable vector format and converts the graphics into compressed bitmaps. This prepared content is then sent to the client device, enabling the client to display the web page with user-adjustable zoom and pan settings while preserving the original layout, similar to how a conventional browser would render it.
• Claim 17 (Method for Mobile Browsing): This claim details a method that allows mobile device users to browse a vast number of web pages. The core steps involve translating received HTML and XML content into a scalable vector format and converting any linked graphic images into compressed bitmaps. These translated and converted files are then transmitted to the mobile device. The mobile device processes these files, allowing the web page content to be displayed on its screen with user-controlled scaling and panning.
• Claim 18 (Computer Program Product): This claim covers a computer program product, essentially software stored on a machine-readable medium (like a disk or flash memory). When a processor executes the instructions of this software, it performs the method described in Claim 17. This includes translating web content and images into scalable vector and compressed bitmap formats, transmitting them to a mobile device, and enabling the mobile device to process and display the content with scalable resolutions and pan offsets.

CAFC 2026 Dockets:
A search of CAFC 2026 dockets for US patent 8145995 did not return any specific litigation entries for this patent number. The search results indicated litigation activity involving SoftView LLC concerning other patent numbers, specifically US7831926B2 and US7461353, but not US8145995.

I am providing an updated response as a patent attorney as of April 26, 2026.

Based on my search, US Patent 8,145,995 appears to be involved in ongoing proceedings primarily related to inter partes reexamination and appeals to the Federal Circuit, rather than district court infringement litigation directly against the patent number 8,145,995, based on the provided search snippets. However, it is closely related to U.S. Patent No. 7,461,353, which is discussed in the context of SoftView LLC's litigation strategy. It appears SoftView LLC is the patent owner.

Here's a summary of the known litigation and related proceedings involving SoftView LLC and, by extension, patents in the same family as US8145995:

• Case: SoftView LLC v. [Apple Inc.](/litigations/by-plaintiff/Apple%20Inc.)

  • Plaintiff(s): SoftView LLC
  • Defendant(s): Apple Inc. (Though the case is against Apple Inc., the direct appeal is from a PTAB decision, where the Director of the United States Patent and Trademark Office is an intervenor).
  • Jurisdiction: U.S. Court of Appeals for the Federal Circuit (CAFC)
  • Case Number: Not explicitly provided in the snippets, but referred to as an appeal from the Patent Trial and Appeal Board (PTAB).
  • Filing Date: The CAFC decision was released on July 26, 2024. SoftView LLC filed a petition for en banc rehearing on August 30, 2024.
  • Outcome/Current Status: The CAFC affirmed in part and reversed in part a judgment of the Patent Trial and Appeal Board. The PTAB had held all claims of SoftView's U.S. Patent No. 7,461,353 invalid under the estoppel provision of 37 C.F.R. § 42.73(d)(3)(i) based on a prior inter partes review (IPR) decision. The Federal Circuit upheld the validity of the regulation and the estoppel standard but agreed with SoftView that the regulation applies to new or amended claims, not previously issued claims. SoftView LLC subsequently filed a petition for en banc rehearing with the CAFC on August 30, 2024, arguing an incorrect application of collateral estoppel/issue preclusion to amended claims.

• Related Proceedings (Inter Partes Review - IPRs):

  • While US8145995 is not explicitly mentioned as the subject of IPRs in the provided snippets, the litigation against Apple Inc. references a prior IPR proceeding involving U.S. Patent No. 7,461,353, which is a related patent from the same family.
  • Petitioner: Kyocera Corp. (in the IPR concerning US 7,461,353).
  • Patent Owner: SoftView LLC.
  • Patent(s) involved in IPR: U.S. Patent No. 7,461,353.
  • Case Number: IPR2013-00007 (for the IPR concerning US 7,461,353).
  • Filing Date: PTAB decision on IPR2013-00007 was March 27, 2014.
  • Outcome: The PTAB invalidated 18 of the 319 claims in U.S. Patent No. 7,461,353.

It's important to note that U.S. Patent No. 8,145,995 is listed as expired as of May 24, 2022, due to fee-related reasons according to its Google Patents entry. This would typically limit new infringement litigation on the patent itself post-expiration, though actions related to prior infringement could still proceed. The recent CAFC and PTAB activities seem to be focused on challenges to the patentability of claims, particularly amended claims, within SoftView's portfolio, as opposed to direct infringement suits on US8145995 in district court.

Proceedings overview

There are no AIA trial proceedings on file for US Patent 8,145,995, based on the USPTO ODP API and supplementary web searches. This means the patent's claims have not been challenged via IPR, PGR, or CBM before the PTAB.

Strategic summary

As of July 17, 2026, all claims of US Patent 8,145,995 remain untested by AIA trial proceedings. The absence of PTAB challenges implies that no petitioner has successfully instituted an IPR, PGR, or CBM on this patent. This could be due to various reasons, such as a lack of strong prior art grounds, the patent owner's enforcement strategy, or the patent's expiration in 2022-05-24 which limits its value for future challenges.

The estoppel provisions of 35 U.S.C. § 315(e)(2) are not applicable, as no AIA trial proceedings were instituted. Therefore, potential defendants are not barred from asserting any prior art grounds that could have been raised in an IPR.

Recommended next steps

Given that US Patent 8,145,995 has no PTAB activity on file and has expired (2022-05-24), any assertion of this patent should be carefully reviewed. The absence of PTAB challenges means its claims have not been subjected to the scrutiny of an AIA trial. A defendant facing assertion of this patent would not be estopped from challenging the patentability of its claims based on prior art.

Most Relevant Prior Art Citations for US8145995

Given the large number of prior art citations, the analysis focuses on the most recent and seemingly relevant patent references that were published before the priority date of US8145995 (June 12, 2000).

1. US6262728B1

   • Full Citation: US6262728B1, Method and apparatus for enabling browsing of web content, granted July 17, 2001.
   • Publication/Filing Date: Filed October 15, 1999; Granted July 17, 2001 (Publication date is typically the grant date for B1 patents; filing date is prior to US8145995's priority date).
   • Brief Description: This patent describes a system and method for browsing web content using a display device. It focuses on converting web content into a format optimized for a target device, where the content is rendered into a bitmap and sent to the device. It discusses techniques for handling different display capabilities, including content scaling, and potentially provides a high-level conceptual overview of adapting content for varied devices.
   • Potential Anticipated Claims (under 35 U.S.C. § 102):
     • Claim 1: This patent potentially anticipates the broad concept of a server-side process for retrieving and converting Internet content for display on a client, especially the "rendering... a display... to enable the user to view the Internet content on the client device." However, it might lack the "scalable vector representation" and "maintaining a substantially identical layout" elements.
     • Claims 2, 9, 10, 11, 15, 16: The general idea of adapting web content for "display devices" (including mobile devices) and using a server-side "converter" could broadly anticipate the server-side translation and client-side viewer concepts.

2. US6184887B1

   • Full Citation: US6184887B1, Method and apparatus for generating display instructions for viewing information, granted February 6, 2001.
   • Publication/Filing Date: Filed April 30, 1998; Granted February 6, 2001.
   • Brief Description: This patent details a system and method for generating display instructions for viewing information on a client. It involves receiving content (e.g., HTML), converting it into an intermediate format (e.g., a "compound document object"), and then generating device-specific display instructions. It aims to provide device-independent content delivery and display.
   • Potential Anticipated Claims (under 35 U.S.C. § 102):
     • Claim 1: The concept of converting content from one format to another for display on a client is present. The "intermediate format" could be considered analogous to a scalable representation, and the generation of "display instructions" aligns with rendering. However, the explicit "scalable vector representation" and the "zooming and panning" based on this representation while "maintaining a substantially identical layout" might be distinguishing features of US8145995.
     • Claims 2, 17: The apparatus claims in US8145995 related to a system for translating and rendering content could be partially anticipated by the system described in US6184887B1.

3. US6185590B1

   • Full Citation: US6185590B1, System and method for displaying and navigating a complex electronic document on a small screen device, granted February 6, 2001.
   • Publication/Filing Date: Filed June 29, 1998; Granted February 6, 2001.
   • Brief Description: This patent directly addresses displaying and navigating complex electronic documents (like web pages) on small-screen devices. It uses a "mini-map" or "overview" to show the entire document and allows users to select a region to zoom into and view in detail. It deals with the challenges of displaying large content on limited screen real estate.
   • Potential Anticipated Claims (under 35 U.S.C. § 102):
     • Claim 1: The core problem of displaying content on small screens and enabling navigation (which implies some form of panning/zooming) is highly relevant. The "mini-map" approach serves a similar purpose to zooming out for context. However, US8145995's emphasis on a scalable vector representation and preserving the original layout during scaling and panning may differentiate it from this prior art, which focuses on displaying regions of a document.
     • Claims 2, 5, 12, 18: The mention of "small screen device" and navigation techniques makes this very relevant to mobile devices and user interaction for viewing portions of the document. The "tap-based inputs to zoom in on selected objects" (Claim 5) might find some conceptual overlap with selecting regions for detailed viewing.

4. US6154784A

   • Full Citation: US6154784A, Client-side web page reformatting system and method, granted November 28, 2000.
   • Publication/Filing Date: Filed July 17, 1998; Granted November 28, 2000.
   • Brief Description: This patent describes a client-side system and method for reformatting web pages to optimize their display on different devices with varying screen sizes and capabilities. It involves modifying the HTML structure and content on the client device itself to better fit the display.
   • Potential Anticipated Claims (under 35 U.S.C. § 102):
     • Claim 1: This is particularly relevant if the reformatting on the client-side involves scaling or adapting content based on screen size, even if not using a "scalable vector representation." The primary distinction here is that US8145995 emphasizes server-side translation to a scalable vector format which is then streamed and rendered, whereas US6154784A focuses on client-side reformatting of the original HTML.
     • Claim 11: The concept of a "client-side viewer" or "stand-alone program" performing rendering is relevant, although the specific mechanism (reformatting HTML vs. rendering vector graphics) differs.

5. US6088722A

   • Full Citation: US6088722A, Method and apparatus for presenting documents on a small display, granted July 11, 2000.
   • Publication/Filing Date: Filed April 10, 1998; Granted July 11, 2000.
   • Brief Description: This patent describes a method and apparatus for presenting documents (including web pages) on small displays. It focuses on techniques like breaking content into "pages" or "chunks" and providing navigation links between them, potentially also summarizing content to fit the display.
   • Potential Anticipated Claims (under 35 U.S.C. § 102):
     • Claim 1: The problem of displaying content on small displays is the same. While it mentions "pages" or "chunks" rather than free scaling and panning of the original layout with vector graphics, the underlying goal of improving content readability on small screens is similar.
     • Claims 2, 5: This patent directly relates to "mobile devices" and "small screen devices" and might involve user interaction for navigation.

These patents highlight existing approaches to adapting web content for different displays, particularly small screens, before the priority date of US8145995. While they address similar problems, US8145995 appears to distinguish itself by explicitly utilizing a "scalable vector representation" (e.g., SVF) for the content, enabling continuous zooming and panning while striving to maintain the original layout of the web page. This differs from prior art that might primarily use bitmap rendering, client-side HTML reformatting, or content chunking.

I am unable to perform a direct obviousness analysis under 35 U.S.C. § 103 for US Patent 8,145,995, as the specific claims of the patent are not provided in the current task. A proper obviousness analysis requires examining the limitations of each claim against the scope of prior art.

However, based on the patent's description of its "Background of the Invention" and "Brief Summary of the Invention," I can analyze the general inventive concepts of US8145995 in light of the prior art explicitly discussed or implied by the patent itself, and hypothesize motivations for combining these elements that would have been apparent to a person having ordinary skill in the art (POSITA) around the priority date of June 12, 2000.

General Inventive Concepts of US8145995

US8145995 aims to provide a "scalable display of Internet (Web) content on mobile devices" to allow Web pages to be scaled (zoomed) and panned for better viewing on smaller screen sizes. Key aspects include:

1. Translation of Web Content: Retrieving and translating HTML, XML, and other Internet content (including CSS) into a "scalable vector representation" (e.g., Simple Vector Format (SVF)). Graphic images are converted into a compressed bitmap format.
2. Resolution-Independent Display: Enabling the display of this translated content in a "resolution-independent" manner, allowing real-time zooming and panning without loss of quality.
3. Maintaining Layout: The rendered displays provide "substantially the same or identical layout as the original Web page."
4. Client-Side Rendering: A "thin client" or "micro-browser" on the mobile device processes and renders the vectorized content, offering zoom and pan functionalities.
5. System Architectures: The translation can occur at a third-party proxy service, a content provider's web server, or directly at the client device.

Prior Art Discussed in US8145995

The patent itself describes the state of the art and its limitations:

• Existing Web Browsers: "Text only Internet information browsers" started at CERN, followed by NCSA's Mosaic.
• Internet Content Formats: Primarily HTML, XML, GIF, and JPEG.
• Limitations of Existing Display: "Font size and resizing display area for content can alter the size of the display of Internet content in existing browsers. The majority of Internet content displays as a flat single resolution with no browser support for zoom."
• Problem with Fixed Resolution: "Much of the Internet content has been designed for display on desktop computers with a single target resolution... This fixed resolution approach... presents a daunting technical problem for display of Internet content (designed for desktop computers) on small screen, low resolution, or different aspect ratio devices, such as cell phones and hand held computers."
• Known Vector Graphics Capabilities: The patent acknowledges that "This “zoom and pan” capability, familiar to CAD and other vector content software users, adds dramatically to the usability of non-standard display sizes." It also explicitly states that SVF "was originally designed to handle a superset of the most commonly used file formats in the complex world of CAD" and "SVF has been under consideration by the W3C (World Wide Web Consortium) for adoption as a standard for vector content on the World Wide Web."

Obviousness Analysis (General Concepts)

A person of ordinary skill in the art (POSITA) in web development, graphics rendering, and mobile computing around the priority date of June 12, 2000, would have been aware of the following:

• Known Problem: The significant difficulty of displaying complex, fixed-layout web pages effectively on the rapidly emerging and diverse array of small-screen, low-resolution mobile devices (e.g., cell phones, PDAs). The patent explicitly identifies this problem.
• Known Solution Principles from Other Fields: Vector graphics (as opposed to raster graphics) inherently offer resolution independence and allow for arbitrary scaling (zooming) without pixelation or loss of quality. The "zoom and pan" functionality was already "familiar to CAD and other vector content software users."
• Existing Vector Formats: Specific vector formats, such as SVF, were known and utilized for their scalability, especially in fields like CAD. The patent notes SVF was "originally designed to handle a superset of the most commonly used file formats in the complex world of CAD." Furthermore, the fact that SVF was "under consideration by the W3C (World Wide Web Consortium) for adoption as a standard for vector content on the World Wide Web" suggests that the concept of using vector formats for web content was already a recognized area of development and discussion.
• Web Content Parsing: Technologies for parsing and interpreting HTML and XML were well-established with conventional web browsers (e.g., Mosaic, Netscape Navigator, Internet Explorer).

Combinations of Prior Art References and Motivation:

Given the known problem and existing technologies, a POSITA would have been motivated to combine the following:

1. Conventional Web Content Retrieval/Parsing (e.g., from Netscape Navigator or Internet Explorer): A POSITA would start with the established mechanisms for fetching and parsing HTML, XML, and associated image files (GIF, JPEG) from web servers. This represents the source content that needs to be adapted.
2. Vector Graphics Technology (e.g., SVF from the CAD arts) with Zoom/Pan Capabilities: Recognizing the limitations of displaying fixed-resolution web content on varied screens, a POSITA would look to known solutions for resolution independence. The established principles and formats from vector graphics, particularly those from CAD applications which already offered robust zoom and pan, would be an obvious choice. The patent itself highlights this familiarity.
3. Mobile Device Platforms (e.g., cellular phones, PDAs): The target environment for the invention, which presented the problem of inadequate web browsing experience.

Motivation to Combine:

The primary motivation for combining these elements would be to solve the acknowledged "daunting technical problem" of effectively displaying web content designed for desktop computers on "small screen, low resolution, or different aspect ratio devices, such as cell phones and hand held computers."

• A POSITA, facing the challenge of enabling a "full Web browsing experience" on mobile devices while maintaining the original "look and feel" of a web page, would logically seek a method to overcome the fixed-resolution nature of traditional web rendering.
• Knowing that vector graphics inherently provide scalability and that "zoom and pan" was a familiar capability in other domains like CAD, it would be an obvious step to apply these known techniques to web content.
• The discussion around SVF's consideration by the W3C further reinforces that the idea of using vector formats for web content was not new or unexpected. A POSITA would realize that converting existing web content (HTML/XML/CSS) into such a scalable vector format would allow for the desired zoom and pan functionality on diverse display sizes without degradation, thereby directly addressing the core problem.

The specific architectural choices (proxy server, web server, or client-side translation) for implementing this conversion would be a matter of engineering design and optimization based on factors like processing power, bandwidth, and desired performance, all of which would be within the purview of a POSITA.
