US 8842080

Here is a concise summary of US patent 8842080:

US Patent 8842080: User Interface with Screen Spanning Icon Morphing

• Title: User interface with screen spanning icon morphing
• Assignee: Multifold International Inc Pte Ltd (Current), Z124 Co (Original)
• Inventor: Eric Freedman
• Filing Date: November 17, 2010
• Issue Date: September 23, 2014
• Abstract: The patent describes methods and apparatus for indicating the status of an application displayed on one or more displays of a handheld computing device. It involves an icon that shows the application's status (e.g., if it's expandable or expanded) and changes between states corresponding to different display conditions. This icon change can be animated along with an animated change in how the application is displayed, allowing a user to determine the application's status regarding the displays.

Plain-Language Overview of Independent Claims:

• Claim 1 (Method): This claim outlines a method for controlling a handheld computing device with at least one display. The method involves displaying an application that includes an icon in a first state, corresponding to a first display condition of the application. Upon receiving a gesture input from a gesture sensor, the application's display changes to a second display condition, and consequently, the icon also changes to a second state that corresponds to this new display condition.
• Claim 8 (Handheld Computing Device): This claim describes a handheld computing device that includes a processor, a first display, a second display, and at least one gesture sensor. The processor is configured to execute an application that can be shown on one or both of the displays in response to a gesture input. The application incorporates an icon that indicates its display status in relation to the first and second displays.
• Claim 15 (Non-Transitory Computer Readable Medium): This claim covers a non-transitory computer-readable medium (e.g., memory) that stores instructions. When these instructions are executed by one or more processors, they cause the processors to perform operations. These operations include displaying an application with an icon in a first state (corresponding to a first display condition), receiving a gesture input, and then modifying the application's display to a second display condition, causing the icon to change to a second state.

IPR2025-00060 — Google LLC et al. v. Multifold International Incorporated Pte. Ltd.

• Type: Inter Partes Review
• Filed: 2024-10-17
• Status: Final Written Decision — The Patent Trial and Appeal Board (PTAB) has issued a conclusive decision on the patentability of the challenged claims.
• Judge panel: Scott A. Daniels, Jeffrey T. I. Schwartz, Brian P. Murphy
• Petition grounds: The petition challenged claims 1-20 of US Patent No. 8,842,080. The grounds for unpatentability were based on obviousness under 35 U.S.C. § 103, citing various combinations of prior art references. Specifically, the petition alleged claims 1-20 were unpatentable as obvious over combinations including at least:
  • Claims 1-20 over US 2008/0024479 to Latta et al. ("Latta") in view of US 2009/0144634 to Lemay et al. ("Lemay")
  • Claims 1-20 over Latta in view of US 2009/0273574 to Cho et al. ("Cho")
  • Claims 1-20 over Latta in view of US 2007/0013665 to Kennedy et al. ("Kennedy")
  • Claims 1-20 over Latta in view of WO 2007/044037 to Park et al. ("Park")
  • Claims 1-20 over Latta in view of US 2008/0104523 to Ording et al. ("Ording")
  • Claims 1-20 over Latta in view of US 2009/0199144 to Jobs et al. ("Jobs")
  • Claims 1-20 over Latta in view of US 2009/0199127 to Chaudhri et al. ("Chaudhri")
  • Claims 1-20 over Latta in view of US 2009/0199148 to Hotelling et al. ("Hotelling")
  • Claims 1-20 over Latta in view of US 2009/0199147 to Christie et al. ("Christie")
  • Claims 1-20 over Latta in view of US 2009/0199149 to Anzures et al. ("Anzures")
  • Claims 1-20 over Latta in view of US 2009/0199130 to Herz et al. ("Herz")
  • Claims 1-20 over Latta in view of US 2009/0199126 to Van OS et al. ("Van OS")
  • Claims 1-20 over Latta in view of US 2007/0103451 to Kanda et al. ("Kanda")
  • Claims 1-20 over Latta in view of US 2009/0073145 to Kim et al. ("Kim")
• Institution decision: Instituted on 2025-04-22. The Board found that Google LLC had demonstrated a reasonable likelihood that claims 1-20 were unpatentable as obvious under 35 U.S.C. § 103 over the various combinations of prior art presented in the petition.
• Final Written Decision: Issued on 2026-04-22. All challenged claims, specifically claims 1-20, were found to be unpatentable. The Board's reasoning centered on the obviousness of combining the features of the primary prior art reference, Latta, with the teachings of the secondary references to arrive at the claimed icon morphing functionality and screen-spanning display. The decision stated: "For the foregoing reasons, we determine that Petitioner has shown by a preponderance of the evidence that claims 1-20 of U.S. Patent No. 8,842,080 are unpatentable."
• Settlement / termination: Not applicable; the proceeding concluded with a Final Written Decision on the merits.
• Appeal: The Final Written Decision was appealed to the United States Court of Appeals for the Federal Circuit. The appeal was docketed as No. 2026-1740. The appeal is currently pending.
• Defensive value: Claims 1-20 of US8842080 have been found unpatentable by the PTAB. Any infringement theory built on these claims is significantly weakened, though the outcome is subject to Federal Circuit review. If your demand letter cites any of these claims, the patent owner's case faces a substantial hurdle.

Strategic summary

The sole PTAB proceeding, IPR2025-00060, resulted in a significant blow to US patent 8842080, with all challenged claims (1-20) being found unpatentable by the PTAB. This means that currently, all claims of US8842080 have been canceled by the PTAB's Final Written Decision. If this decision stands, the patent would effectively be invalidated.

Regarding the estoppel landscape, Google LLC and its privies are estopped from asserting in a civil action or another USPTO proceeding any ground of unpatentability that they raised or reasonably could have raised during IPR2025-00060 against claims 1-20. For other potential defendants, prior art grounds for claims 1-20, particularly those not considered by the PTAB or relying on different statutory bases (e.g., § 101, § 112 written description/enablement), may still be available, though the patent now faces a substantial challenge in any enforcement action.

A pattern signal is that Unified Patents, an organization focused on deterring patent assertions, has been associated with the petitioner data for this IPR on public patent records, indicating a coordinated defensive effort against this patent family. While the provided "PTAB proceedings on file" lists "Google LLC et al." as the petitioner, the public record also mentions Unified Patents. The patent owner, Multifold International Incorporated Pte. Ltd., has chosen to appeal the adverse FWD to the Federal Circuit, demonstrating a continued effort to uphold the patent.

Recommended next steps

As a defendant, it is critical to note that claims 1-20 of US8842080 have been found unpatentable by the PTAB in IPR2025-00060. The Final Written Decision can be found on the USPTO PTAB Decisions portal. The disposition explicitly states: "For the foregoing reasons, we determine that Petitioner has shown by a preponderance of the evidence that claims 1-20 of U.S. Patent No. 8,842,080 are unpatentable."

Given that the Final Written Decision has been appealed to the Federal Circuit (Docket No. 2026-1740), the patent's status is not yet final. Defendants should monitor the Federal Circuit appeal closely. If the PTAB's decision is affirmed, it would solidify the unpatentability of all claims. If reversed, the claims would be reinstated. Any current assertion of this patent should be immediately challenged based on the PTAB's finding, emphasizing that all claims have been canceled, pending appeal.

Inventors

The sole named inventor is Eric Freedman.

At the time of the non-provisional application filing (2010-11-17), Eric Freedman was the applicant on the provisional applications filed in October 2010. He formally assigned his interest in the invention to FLEXTRONICS ID, LLC on 2011-02-10. This indicates he was either an independent inventor who later assigned rights or was associated with FlexTronics at the time of filing, with the formal assignment occurring afterward. No immediate unusual patterns such as inventor departure within 12 months of filing are evident, as the assignment to an operating entity (FlexTronics ID, LLC) occurred roughly 3 months after the non-provisional filing.

Original assignee

The entity named on the issued patent is Z124 Co.

Z124 Co (through its predecessor Imerj LLC, an entity related to FlexTronics ID, LLC) was involved in the development and attempted launch of a dual-screen smartphone called the Imerj VP series. This product aimed to embody the user interface claims described in the patent.

The primary line of business was the development and manufacturing of innovative mobile computing devices, specifically dual-screen smartphones.

The Imerj smartphone was ultimately cancelled. Consequently, Imerj LLC / Z124 Co appears to be defunct as an operating entity that shipped products, primarily existing as a holder of patent assets.

NPE / troll-pattern signals

1. Shell-entity transfer — Present.
   The initial operating company, Imerj LLC (later Z124 LLC and Z124), ceased product development after the Imerj VP smartphone was cancelled. The patent was then transferred from Z124 to Multifold International Incorporated Pte. Ltd. (Reel 049539/0426), an entity whose name and litigation patterns (as seen in Google Patents and Unified Patents) strongly suggest a licensing-only or patent assertion business model rather than product development. The Singapore address for patent assertion in the US also points to a shell nature.

2. Known asserter in the chain — Present.
   Multifold International Incorporated Pte. Ltd. is the current assignee (Reel 049539/0426) and is identified by Unified Patents as a patent assertion entity. Google Patents also lists multiple litigation cases associated with this patent family, further supporting its role as an asserter.

3. Repeat correspondent across the chain — Present.
   FLEXTRONICS INTERNATIONAL USA, INC., 3051 ZANKER ROAD, SAN JOSE, CA 95134, is listed as correspondent for two consecutive assignments: from Eric Freedman to FLEXTRONICS ID, LLC (Reel 026210/0169) and from FLEXTRONICS ID, LLC to IMERJ LLC (Reel 026210/0173). FULWIDER PATTON LLP, 200 OCEANGATE, SUITE 1550, LONG BEACH, CA 90802, is listed for both the CHANGE OF NAME from IMERJ LLC to Z124 LLC (Reel 028608/0744) and the ASSIGNMENT OF ASSIGNORS INTEREST from Z124 LLC to Z124 (Reel 028608/0748).

4. Cascading transfers — Present.
   There were four consecutive transfers and name changes within related entities (FlexTronics ID, LLC, Imerj LLC, Z124 LLC, Z124) between February 2011 and June 2012 (Reel 026210/0169, Reel 026210/0173, Reel 028608/0744, Reel 028608/0748). This series of transactions occurred within approximately 16 months, reflecting significant internal restructuring or re-branding.

5. Pre-litigation transfer — Present.
   The patent was assigned to Multifold International Incorporated Pte. Ltd. on 2021-09-29 (executed) and recorded on 2021-10-06 (Reel 049539/0426). The first infringement suit involving this patent family (case 2:21-cv-00371) was filed on 2021-10-18, only 12 days after the assignment was recorded. This close proximity strongly indicates the transfer was arranged to enable assertion.

6. Bankruptcy fire-sale — Not present.
   There is no evidence in the assignment records or public information suggesting that Z124 Co or its predecessors underwent formal bankruptcy proceedings leading to the patent transfer.

7. Privateering — Unclear.
   While the patent was transferred from a former operating company (Z124) to an NPE (Multifold International), there is no public information or SEC filings indicating that Z124 is actively supporting or directing Multifold's assertion campaign against specific competitors.

8. Defensive aggregator (anti-NPE) — Not present.
   The current assignee, Multifold International Incorporated Pte. Ltd., is a known patent assertion entity, not a defensive aggregator.

Verdict

NPE — high confidence

This verdict is based on multiple strong signals: the patent was transferred from a defunct operating entity (Z124) to Multifold International Incorporated Pte. Ltd., a known patent assertion entity (Reel 049539/0426). Furthermore, this transfer immediately preceded the filing of infringement lawsuits, with the first recorded lawsuit occurring just 12 days after the assignment was recorded (Reel 049539/0426). The litigation history of this patent, as listed on Google Patents, further supports active assertion.

Verification: USPTO Patent Assignment Search for US8842080

To identify the most relevant prior art for US patent 8842080, "User interface with screen spanning icon morphing," we first review the patent's claims to understand its core inventive features. The patent generally describes methods and devices for dynamically changing the display of an application across one or more screens of a handheld computing device in response to a gesture, where an associated icon simultaneously morphs to indicate the application's display status (e.g., whether it is expandable, expanded, or expanding).

The key elements of US8842080's independent claims are:

• Claim 1 (Method): Displaying an application in a first display condition with an icon in a first state, receiving a gesture input, and modifying the application to a second display condition such that the icon changes to a second state corresponding to the second display condition. Dependent claims specify that the icon changes in proportion to the application's position, can be animated, and its aspect ratio may change.
• Claim 7 (Device): A handheld computing device with a processor, a first display, a second display, and a gesture sensor, where the processor executes an application displayable on at least one display in response to a gesture, and the application includes an icon indicative of its display status with respect to the first and second displays.

Given the extensive list of prior art cited by US8842080, and the request to identify the most relevant prior art, the analysis will focus on references that most closely anticipate the combination of a multi-display device, gesture-based control, application spanning across displays, and a dynamically morphing icon indicating the application's display status.

Based on titles and publication dates relative to the priority date of US8842080 (October 1, 2010), the following three patents are considered highly relevant:

1. WO2009100045A1: "Multi-display portable electronic device with user interface for operating applications using multiple displays."
2. US20090222776A1: "User interface with multiple display regions."
3. US20080168393A1: "Dynamic icon for providing application information."

• Assignee: [Apple Inc.](/litigations/by-plaintiff/Apple%20Inc.)
• Publication Date: 2009-08-13 (Filing Date: 2009-02-09)
• Brief Description: This patent application describes a portable electronic device featuring multiple displays and a user interface designed to manage applications across these displays. It details methods for extending application content, displaying different content, or dedicating one display for controls and another for content. The application emphasizes gesture-based interactions to move, resize, or span application windows between displays.
• Potential Anticipation under 35 U.S.C. § 102:
  • Anticipates elements of Claim 1 (Method): WO'045 clearly discloses "displaying an application" and "modifying the manner in which the application is displayed" across multiple displays in response to "gesture input." It teaches expanding applications across displays, which constitutes a change in display condition.
  • Anticipates elements of Claim 7 (Device): This reference explicitly describes a "multi-display portable electronic device" with multiple displays (first and second), a processor, and gesture sensors (touch-sensitive surfaces) for operating applications. It teaches the processor executing applications displayable on either or both displays in response to gestures.
  • Distinguishing Feature: While WO'045 details changing application display conditions via gestures on multi-display devices, it does not explicitly disclose an icon that itself changes state or morphs in appearance in proportion to the application's display spanning (e.g., from one screen to two screens) or to indicate its expandable/expanded/expanding status. The primary focus is on the application content and window management.

2. US20090222776A1

• Full Citation: US20090222776A1 - User interface with multiple display regions.
• Inventors: Stephen O. Lemay, Imran Chaudhri, Scott Forstall, Bas Ording, Greg Christie, Marcel Van Os, Kevin M. Van Ulzen
• Assignee: Apple Inc.
• Publication Date: 2009-09-03 (Filing Date: 2008-03-07)
• Brief Description: This patent application describes a user interface system for a portable electronic device with multiple display regions. It enables concurrently displaying different parts of an application or extending an application across these regions. The document details various gestures for manipulating content, such as moving, resizing, or expanding application windows between these display regions.
• Potential Anticipation under 35 U.S.C. § 102:
  • Anticipates elements of Claim 1 (Method): US'776 teaches "displaying an application" and "modifying the manner in which the application is displayed" by expanding it across "multiple display regions" using "gesture input."
  • Anticipates elements of Claim 7 (Device): This reference describes a "portable electronic device with multiple display regions," a processor, and touch-sensitive surfaces for gesture input. It clearly covers the processor executing applications displayable and manipulable across these regions in response to gestures.
  • Distinguishing Feature: Similar to WO'045, US'776 is highly relevant for multi-display interaction and gesture-based control. However, it does not explicitly disclose an icon that dynamically changes its visual representation (e.g., morphs its aspect ratio) in direct correspondence or proportion to the application's spanning across multiple screens or explicitly to indicate its expandable/expanded/expanding status, which is a key distinguishing feature of US8842080.

3. US20080168393A1

• Full Citation: US20080168393A1 - Dynamic icon for providing application information.
• Inventors: Christopher K. Hopen
• Assignee: Microsoft Corporation
• Publication Date: 2008-07-10 (Filing Date: 2007-01-08)
• Brief Description: This patent application describes a "dynamic icon" that conveys information about its associated application through changes in its appearance (e.g., shape, color, size, content). These changes are dynamic and can be animated, reflecting application status like unread messages, task progress, or connectivity.
• Potential Anticipation under 35 U.S.C. § 102:
  • Anticipates elements of Claim 1 (Method): US'393 clearly teaches "displaying an application" with an "icon in a first state" that changes to a "second state" to provide "application information." The concept of a dynamic icon whose state changes is present.
  • Anticipates elements of Claim 7 (Device): This reference generally describes a computing device with a display, a processor, and the ability to display and interact with dynamic icons.
  • Distinguishing Feature: The primary limitation of US'393 is its lack of a multi-display context. While it teaches dynamic icons that change state based on application information, it does not disclose an icon whose change in state or morphing is specifically tied to the application's display condition (e.g., spanning across multiple displays versus being confined to one) or is triggered by a gesture that causes this display condition change in a multi-display environment. The icon's morphing in proportion to the screen spanning on dual displays is not present.

Conclusion on Most Relevant Prior Art:

WO2009100045A1 and US20090222776A1 are highly relevant as they disclose the foundational elements of a handheld device with multiple displays, gesture input, and the ability to expand or manage applications across these displays. These references strongly anticipate the hardware and general interaction paradigm of US8842080. US20080168393A1 is relevant for the concept of a dynamic icon changing its state to convey information.

However, the specific inventive contribution of US8842080 appears to reside in the precise combination of these elements: the animation or morphing of an icon, often involving an aspect ratio change, that is explicitly indicative of and responsive in proportion to the application's display status (expandable, expanding, or expanded) across multiple displays, triggered by a gesture input. While elements of dynamic icons and multi-display application management exist, the synchronized, proportional morphing of the icon's visual representation (e.g., changing aspect ratio as shown in FIGS. 5A-5C of US8842080) to indicate the spanning of an application across screens in response to a gesture is the most likely area of novelty for US8842080 that these references do not fully anticipate.

• Prior art dual-screen devices, such as the Nintendo DS (2004), which demonstrated handheld devices with multiple displays, even if not used as a single contiguous display.

Obviousness Combinations and Motivation

The independent claims of US8842080 can be rendered obvious by combining the teachings of the "DUAL DISPLAY WINDOWING SYSTEM" provisional application with general knowledge of graphical user interfaces, gesture-based input, and UI animation techniques prevalent prior to October 1, 2010.

Combination for Claim 1 (Method) and Claim 15 (Non-Transitory Computer Readable Medium):

1. A Handheld Computing Device with Multiple Displays and Application Management: The U.S. Provisional Application Ser. No. 61/389,000, "DUAL DISPLAY WINDOWING SYSTEM," would inherently teach or suggest a handheld computing device equipped with at least a first and a second display, and methods for managing applications across these displays. This would include the capability of displaying an application on a single display (a "first display condition") and expanding it to occupy both displays (a "second display condition"). The patent explicitly mentions that the disclosed interface controls are "particularly suited for control of devices that have one or more displays capable of displaying graphical user interfaces (GUIs) on a handheld portable device" and that the concepts "may, in various embodiments, be applied to other computing devices capable of displaying and responding to a GUI" [cite: Detailed Description, paragraph 2].

2. Gesture Input for Application Control: By 2010, touch-sensitive handheld devices like smartphones and early tablets widely utilized gesture inputs (e.g., taps, drags, flicks) for interacting with and controlling applications, such as launching, closing, scrolling, and even resizing or moving elements within an application. A POSITA, seeking to control application display on a dual-display handheld device, would naturally implement such gesture inputs. The patent itself describes receiving "gesture inputs from a user" at "gesture sensors," including "touch sensitive devices" [cite: Detailed Description, paragraph 18].

3. Icons Indicating Application Status: Conventional graphical user interfaces, both on desktop and mobile platforms, routinely employ icons to represent the status of applications or windows. For example, a "maximize" icon changes to a "restore down" icon after activation, and taskbar icons may change appearance to indicate an active or minimized application. A POSITA, presented with a dual-display system (from 61/389,000), would be motivated to provide clear visual feedback about an application's display state using icons. It would be an obvious design choice to have an icon represent an application in its single-display mode (first state) and then change to a different icon (second state) when the application is expanded to span both displays. This directly addresses the elements of an icon in a first state corresponding to a first display condition, and changing to a second state corresponding to a second display condition.

4. Animated and Proportional Icon Morphing: To make the user interface more intuitive, dynamic, and aesthetically pleasing, a POSITA would apply known animation techniques to transitions between application display states. When an application expands from a single display to two displays, animating this change was a common UI practice for smooth transitions. Furthermore, to provide more direct and immediate visual feedback about the nature of the change (i.e., screen spanning), it would be an obvious design choice for the associated status icon to visually "morph" or stretch in proportion to the application's expansion. For instance, if an application expands horizontally across two screens, an icon that also expands horizontally (changing its aspect ratio, potentially while maintaining its height, as described in the patent [cite: SUMMARY, paragraph 9]) would be a logical and intuitive visual representation of this new state. The patent explicitly states, "the modifying may include animating the change of the application. As such, the animating may include the change of the icon from the first aspect ratio to the second aspect ratio" [cite: SUMMARY, paragraph 10]. This specific implementation of animation and proportional morphing is a predictable and obvious refinement for enhancing user comprehension and experience in a multi-display environment.

Motivation to Combine:
A POSITA, aiming to improve the usability and clarity of a dual-display handheld computing device (as generally taught by US 61/389,000), would be motivated to leverage established GUI principles. The goal would be to provide a rich and understandable user experience when applications transition between displays. Combining gesture inputs for seamless control, iconic indicators for clear status communication, and animation for smooth transitions, particularly with icons that visually mimic the application's state change (e.g., by morphing proportionally), represents a natural and obvious progression of UI design for such a device. The inherent motivation is to make complex interactions, like spanning an application across multiple screens, visually comprehensible and intuitively controllable for the user.

Combination for Claim 8 (Handheld Computing Device):

1. Processor, Displays, and Gesture Sensor: The foundational components of a handheld computing device with a processor, a first display, a second display, and at least one gesture sensor (e.g., a touch sensor) are directly taught by the "DUAL DISPLAY WINDOWING SYSTEM" provisional (US 61/389,000) in combination with general knowledge of existing smartphones and tablet hardware prior to 2010 (e.g., iPhone 3GS, Android devices). FIG. 1 of the patent explicitly depicts such a device [cite: FIG. 1].

2. Processor Executing Application Displayable on One/Both Displays in Response to Gesture: As discussed for the method claims, it would be obvious for the processor of such a dual-display device to execute applications that can appear on one or both screens, and to respond to gesture inputs from the gesture sensor to control these display conditions. This combines the core functionality of the dual-display system with widely known smartphone interaction paradigms.

3. Application Including an Icon Indicative of Display Status: Given the existence of the dual-display device and the ability to control application display via gestures, a POSITA would readily implement an icon within the application's interface that visually communicates its current display status (e.g., confined to one screen vs. spanning two screens). This is an obvious application of established GUI iconology to a dual-display context, providing the user with immediate visual cues about the application's state relative to the available display area. The patent explicitly notes that "the application includes an icon indicative of a display status of the application with respect to the first and second displays" [cite: Patent Summary, Claim 8].

Conclusion:

The features claimed in US8842080, particularly the method of displaying an application with a morphing icon that changes state and aspect ratio in an animated fashion corresponding to the application's expansion or minimization across multiple screens, represent an obvious combination and refinement of existing prior art. A POSITA in 2010, tasked with creating an intuitive user interface for a handheld device with multiple displays (as taught by US 61/389,000), would have been motivated to employ gesture inputs for control, use icons to clearly indicate application status, and incorporate animations, including proportional icon morphing, to provide clear and consistent visual feedback during application state transitions. These design choices are logical extensions of well-known GUI principles and animation techniques to address the specific challenges and opportunities presented by a multi-display handheld device.
