II. Technology and Patent(s)-in-Suit Analysis

U.S. Patent No. 7,386,322 - Advanced Cellular Telephone with Data Processing and Information Display Capabilities, issued June 10, 2008

The Invention Explained

  • Problem Addressed: The patent family addresses the fragmentation of the wireless communication industry, where numerous competing technologies (e.g., different cellular standards, paging services, data networks) operate on different frequencies with different protocols, preventing a single device from working seamlessly across them ('985 Patent, col. 1:22–38).
  • The Patented Solution: The invention is an "advanced cellular telephone" designed to be "omni-modal," meaning it can communicate over multiple distinct wireless networks, such as a Personal Communication Services (PCS) network and at least one other network ('322 Patent, Abstract). It achieves this through an "omni-modal communication circuit" that includes a transceiver, modulator/demodulator circuitry, memory, and a processor that controls connections and manages voice and data functions based on user commands received via a touch-sensitive device ('322 Patent, col. 5:2–6:15; Fig. 1B).
  • Technical Importance: The technology represents an early approach to unifying device functionality in a multi-standard wireless environment, enabling a single handset to opportunistically use different networks for voice and data communication ('985 Patent, col. 2:27–34).

Key Claims at a Glance

  • The complaint asserts independent claim 1 and dependent claims 5 and 16 (Compl. ¶21).
  • Essential Elements of Independent Claim 1:
    • An advanced cellular telephone for facilitating communication over a plurality of wireless networks (including a PCS network and at least one additional network).
    • A housing small enough to form a portable handset.
    • An antenna supported by the housing.
    • A display supported by the housing for displaying information.
    • A touch-sensitive device for receiving user commands.
    • An omni-modal communication circuit, comprising a transceiver, digital modulator/demodulator circuitry, memory for storing an operating program, and a processor for setting up connections and controlling the device.
    • A final "wherein" clause stating that functions like information retrieval and placing calls are carried out by selective access to the networks under the control of the processor.
  • The complaint does not explicitly reserve the right to assert additional claims.

U.S. Patent No. 6,934,558 - Adaptive Omni-Modal Radio Apparatus and Methods, issued August 23, 2005

The Invention Explained

  • Problem Addressed: As with the '322 patent, this invention tackles the problem of enabling a single device to navigate a fragmented wireless landscape with numerous service providers and technologies ('985 Patent, col. 1:22–38).
  • The Patented Solution: This patent focuses on the intelligent decision-making process for network selection. It describes a multi-modal device with an "adaptive control circuit" that determines which wireless networks are available and then generates the necessary frequency and protocol control signals to connect to a specific network. This selection is made "in response to a user defined individual priority," which can include criteria such as cost, signal quality, or security ('558 Patent, Abstract; '985 Patent, col. 2:40–53).
  • Technical Importance: The invention moves beyond simple multi-network capability to an adaptive system where the device's behavior is guided by user preferences, allowing for optimized network selection based on factors other than mere availability ('985 Patent, col. 17:21–50).

Key Claims at a Glance

  • The complaint asserts independent claim 1 and dependent claims 7 and 8 (Compl. ¶39).
  • Essential Elements of Independent Claim 1:
    • A multi-modal device for communication over a plurality of wireless networks.
    • A frequency agile radio transceiver capable of operating at frequencies appropriate for each network.
    • An interface circuit for interconnecting the transceiver with an external signal circuit.
    • A protocol agile operating circuit for operating the transceiver in accordance with different modulation protocols.
    • An adaptive control circuit for determining available networks and generating control signals to access a selected network.
    • The generation of control signals is done in response to a "user defined individual priority."
    • Input means for receiving and storing the user-defined priority.
    • A final "wherein" clause stating the adaptive control circuit generates the control signals to connect to a network that is both available and satisfies the user-defined priority.
  • The complaint does not explicitly reserve the right to assert additional claims.

IV. Analysis of Infringement Allegations

7,386,322 Infringement Allegations

Claim Element (from Independent Claim 1) Alleged Infringing Functionality Complaint Citation Patent Citation
a housing small enough to form a portable handset The accused devices, such as the GSM OT Series OT-303 phone, include a housing with small proportions suitable for a portable handset. ¶25 col. 12:45-53
an antenna supported by the housing for transmitting and receiving electromagnetic energy Each accused handset includes an internal antenna that converts RF signals to electrical signals and transmits signals from the terminal. ¶26 col. 6:15-17
a display, supported by the housing, for displaying information that is visually perceptible to a user Each accused mobile device includes a display for presenting visually perceptible information to the user. ¶27 col. 10:45-54
a touch-sensitive device for receiving user supplied commands and data The accused devices use a touch-sensitive keypad for receiving user commands. The complaint provides an image of a keypad from an exemplary device (Compl. p. 7). ¶28 col. 10:55-67
an omni-modal communication circuit for accessing the wireless communication networks... [comprising] a transceiver... digital modulator circuitry... memory... [and] a processor The accused devices contain an omni-modal circuit with a transceiver, digital modulator/demodulator, memory chips, and processors (e.g., the MT6226 chip) to access multiple networks like PCS. ¶29-35 col. 7:20-8:67
wherein the functions of information retrieval... may be carried out by selective access, under the control of the processor... The accused handsets perform functions like placing calls and retrieving information by selective access to multiple networks, with the user able to select "Automatic" or "Manual" modes. ¶37 col. 9:18-24
  • Identified Points of Contention:
    • Scope Questions: A potential issue is whether the term "touch-sensitive device" can be construed to cover the physical, button-based keypad depicted in the complaint (Compl. ¶28, p. 7), as this term is often associated with modern touchscreens. The interpretation of "omni-modal communication circuit" will also be critical; a dispute may arise over whether the highly integrated chipsets in the accused devices correspond to the more discretely defined sub-components (transceiver, modulator, memory, processor) listed in the claim.
    • Technical Questions: The complaint's allegation of "selective access" is supported by the user's ability to choose "Automatic" or "Manual" network selection (Compl. ¶37). The factual question for the court may be whether this functionality is equivalent to the processor-controlled access to a plurality of networks as required by the claim.

6,934,558 Infringement Allegations

Claim Element (from Independent Claim 1) Alleged Infringing Functionality Complaint Citation Patent Citation
a frequency agile radio transceiver capable of operating at any frequency or frequencies appropriate for each of the plurality of wireless communication networks The accused products include transceivers that are "frequency agile," meaning they can switch between frequencies to connect to a plurality of wireless networks. ¶43 col. 6:15-25
an interface circuit for interconnecting said frequency agile radio transceiver with an external signal circuit The transceivers are interconnected via an interface circuit with external digital signal processing devices. ¶45 col. 10:5-10
a protocol agile operating circuit for operating said frequency agile radio transceiver... in accordance with any one modulation protocol The accused products include a protocol agile operating circuit, as they utilize different protocols when operating on different networks. ¶47 col. 6:4-14
adaptive control circuit for determining which wireless communications networks are available... and for generating the frequency control signal and the protocol control signal in response to a user defined individual priority The accused handsets include an adaptive control circuit that exchanges information with a base station to determine available networks and generates control signals to connect based on user-defined criteria. ¶49-50 col. 2:35-53
input means for receiving and storing the user defined individual priority for selecting among the plurality of wireless communication networks The input means is the handset's alpha-numeric keypad and navigation keys, which permit the user to enter criteria for guiding network selection. ¶51-52 col. 12:56-61
wherein said adaptive control circuit operates to generate said frequency control signal and said protocol control signal... [that] satisfies said user defined individual priority The devices include circuitry that generates the necessary control signals to connect to a selected wireless network that is determined to be available and satisfies the user-defined priority. ¶54 col. 13:8-12
  • Identified Points of Contention:
    • Scope Questions: The central dispute may turn on the construction of "adaptive control circuit" and "user defined individual priority." The question is whether standard functionality in a modern operating system—such as automatically registering with a preferred system while roaming (Compl. ¶50)—meets the claim's requirements for an "adaptive" circuit acting on "user defined priority."
    • Technical Questions: The complaint alleges that because the handsets use different protocols, they "by definition have a protocol agile operating circuit" (Compl. ¶47). This conclusory statement raises the factual question of whether the accused products contain a distinct circuit that performs the claimed function or if this is merely an inherent result of having a multi-protocol transceiver.

V. Key Claim Terms for Construction

  • The Term: "omni-modal communication circuit" ('322 Patent, Claim 1)

  • Context and Importance: This term is the technological core of the '322 patent's asserted claim. The claim itself provides a structural definition by listing its constituent parts (transceiver, modulator, memory, processor). The construction of this term will determine whether modern, highly integrated system-on-a-chip (SoC) architectures, which may not have physically discrete components corresponding to the claim language, fall within the patent's scope.

  • Intrinsic Evidence for Interpretation:

    • Evidence for a Broader Interpretation: The specification describes the circuit as a "standard building block" intended for use in a "wide variety of products," which may support a more functional interpretation not strictly tied to a specific physical layout ('985 Patent, col. 3:59-65).
    • Evidence for a Narrower Interpretation: The detailed description and Figures 1A and 1B provide a specific block diagram showing discrete, interconnected components ('985 Patent, Figs. 1A-1B; col. 6:15–col. 8:67). A party may argue that the claim scope is limited to this disclosed architecture.

  • The Term: "adaptive control circuit... in response to a user defined individual priority" ('558 Patent, Claim 1)

  • Context and Importance: This phrase is crucial for determining infringement of the '558, '453, and '985 patents. Practitioners may focus on this term because the dispute will likely center on whether the automated or semi-automated network selection features of the accused devices (e.g., roaming preferences) constitute the claimed "adaptive" control based on "user defined priority."

  • Intrinsic Evidence for Interpretation:

    • Evidence for a Broader Interpretation: The abstract suggests user-defined criteria can include broad concepts like "cost," "quality of transmission link," or "security" ('558 Patent, Abstract). The complaint alleges that allowing a user to select "Automatic" or "Manual" network search is sufficient to meet this limitation (Compl. ¶37).
    • Evidence for a Narrower Interpretation: The specification provides a detailed example of a weighted scoring algorithm where a user assigns percentage values to different factors (e.g., 80% on cost, 20% on signal quality) to calculate a "score" for each network ('985 Patent, col. 17:21–50). This may support an argument that the claims require a more sophisticated, multi-factor decision-making process than a simple network preference list.

VI. Other Allegations

  • Indirect Infringement: The complaint alleges induced infringement, stating that Defendant had knowledge of the patents since at least September 2008 (Compl. ¶89). It is alleged that Defendant induced its customers to infringe by supplying products with instructions and software (e.g., "connection driver software") that, when used as intended, perform the infringing multi-modal communication functions (Compl. ¶89-91).
  • Willful Infringement: Willfulness is alleged based on Defendant’s purported pre-suit knowledge of the patents. The complaint cites the 2008 notice letters and subsequent licensing correspondence between Defendant and Plaintiff's predecessor as evidence that Defendant's infringement was undertaken with knowledge of the patents (Compl. ¶8, ¶94).

VII. Analyst’s Conclusion: Key Questions for the Case

  • A core issue will be one of functional scope: do the standard network-selection features in the accused products' operating systems (e.g., automatic roaming preferences, manual network search) perform the specific, multi-factor, criteria-based decision-making required by the "adaptive control circuit" claims, or is there a fundamental operational difference between the accused functionality and the patented invention?
  • A key claim construction question will be one of structural definition: can the term "omni-modal communication circuit," defined in the '322 patent claim by its constituent parts (transceiver, modulator, memory, processor), be construed to read on the highly integrated mobile device chipsets in the accused products, or is its scope limited by the more discrete component architecture depicted in the patent's specification?
  • Given that the patents expired in 2013, a central focus will be the quantification of historical damages. The extensive pre-suit history, including notice letters dating to 2008, will be critical to the determination of willfulness and any potential for enhanced damages, framing the case as an entirely backward-looking monetary dispute.
