Case Timeline

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

U.S. Patent No. 6,973,535 - Digital Device Configuration and Method

The Invention Explained

• Problem Addressed: The patent describes the challenge of designing complex digital storage devices, particularly for portable electronics, which require both high data capacity and resilience to physical shock ('535 Patent, col. 1:15-41). A further problem is the complexity of managing communications between multiple internal components of a storage device, such as the servo controller and read/write channel, which traditionally required distinct firmware and control interfaces ('535 Patent, col. 4:21-5:19).
• The Patented Solution: The invention discloses a system for managing internal communications within a storage device using a unified serial interface. It proposes a "primary serial gateway" that interfaces with a host device and a "serial router" that directs commands and data to specific internal components (e.g., servo, preamp, read/write electronics) based on a device ID ('535 Patent, Abstract; col. 11:1-44). This architecture aims to create a more flexible and standardized method for controlling the disparate parts of a hard drive.
• Technical Importance: This approach sought to simplify the design and firmware management of hard disk drives by creating a centralized, configurable communication bus, potentially reducing development costs and improving the ability to customize drive operations ('535 Patent, col. 6:1-29).

Key Claims at a Glance

• The complaint asserts at least indirect infringement of claim 20 (Compl. ¶16).
• Independent Method Claim 20:
  • A method of configuring a digital data storage arrangement.
  • Configuring a primary serial gateway, forming part of the storage arrangement, for externally bi-directionally transferring serial control-related data used in operating said devices.
  • Arranging a host serial interface, as part of the host device, for applying a serial protocol to the data passing between the host and the storage arrangement.
  • Using a serial router, part of the storage arrangement and in communication with the primary serial gateway, to manage the serial control-related data between the gateway and each of the device serial interfaces.

U.S. Patent No. 7,546,411 - Digital Device Configuration and Method

The Invention Explained

• Problem Addressed: As a continuation of the technology in the '535 Patent, the '411 Patent also addresses the need for efficient and reliable control over the internal components of an electromechanical storage device ('411 Patent, col. 1:19-2:1).
• The Patented Solution: The invention describes a digital storage configuration that uses a clock signal as a "time base reference" for writing data to the disk. It employs a "serial gateway" and a "serial router" to provide and direct bi-directional control data, which is clocked by the signal, to selected digital devices within the storage arrangement via a dedicated serial interface ('411 Patent, Abstract; col. 12:54-13:8).
• Technical Importance: This system aimed to provide precise, clock-based synchronization for data writing and internal device commands, which could enhance the reliability and performance of the storage device's electromechanical operations ('411 Patent, col. 12:62-64).

Key Claims at a Glance

• The complaint asserts at least indirect infringement of claim 1 (Compl. ¶25).
• Independent System Claim 1:
  • An electromechanical digital data storage arrangement with a disk for storing first data.
  • Two or more digital devices, each with a dedicated serial interface.
  • A serial gateway to provide bi-directional control data clocked by a clock signal.
  • Means for writing the first data to the disk using the clock signal as a time base reference.
  • A serial router to route the control data to a selected digital device.
  • A control block to set the serial router to implement a command set for the selected device.
  • Means for routing the control data to the selected device via its dedicated serial interface.

III. The Accused Instrumentality

Product Identification

The complaint identifies the "Pegatron White Box Server Solution" as an exemplary infringing system (Compl. ¶17, 26). These servers are alleged to incorporate third-party hard disk drives (HDDs) from Western Digital and Hitachi Global Storage Technologies (HGST), such as the "Ultrastar DC HC350" and "Ultrastar DC HC530" (Compl. ¶11, 16, 17, 26). The complaint includes an image and specifications for a "2U Rackmount Server_ Intel Platform," identifying it as an accused product type (Compl. p. 4).

Functionality and Market Context

The accused instrumentalities are servers and computer systems manufactured and sold by Pegatron (Compl. ¶11, 12). The infringement allegations center on the functionality of the HDDs contained within these servers (Compl. ¶17, 26). The complaint alleges that the internal architecture of these HDDs—including their rotatable disks, actuator arms, servo electronics, and serial interfaces—performs the patented methods of device configuration and control (Compl. ¶17, 26). Pegatron is positioned as a "leading manufacturer and seller of computers and storage equipment" (Compl. ¶2).

IV. Analysis of Infringement Allegations

'535 Patent Infringement Allegations

'411 Patent Infringement Allegations

• Identified Points of Contention:
  • Technical Questions: The complaint's allegations track the claim language closely but provide little specific evidence of how the accused HDDs' internal components function. A key question for the court will be whether the controller architecture in the accused WD and HGST drives actually practices the claimed "serial gateway" and "serial router" configuration, as opposed to other known data bus architectures.
  • Scope Questions: The case may raise the question of whether Pegatron, as an integrator of third-party components, is the proper target for direct infringement claims that are based on the internal operation of those components. The dispute may focus on whether Pegatron's act of "making, using, [or] selling" the server system constitutes an infringing use of the patented HDD technology within.
  • Means-Plus-Function: Claim 1 of the '411 Patent includes "means for writing" and "means for routing" limitations. A central dispute will be whether the accused products contain structures that are identical or equivalent to the specific structures disclosed in the '411 Patent's specification for performing these functions. The complaint does not identify these corresponding structures.

V. Key Claim Terms for Construction

• The Term: "serial gateway"

  • Context and Importance: This term appears in the independent claims of both asserted patents and is fundamental to the claimed invention's architecture. Its construction will be critical in determining whether the interface controllers in the accused HDDs meet this limitation.
  • Intrinsic Evidence for a Broader Interpretation: The specification describes the gateway as part of a system that provides an "interface between the host device and the storage element," which could support a broad interpretation covering various types of controller interfaces ('535 Patent, col. 11:1-3).
  • Intrinsic Evidence for a Narrower Interpretation: The detailed description and figures show specific implementations, such as "Serial Gateway 1350" in Figure 22, which is connected to specific control and data lines ('535 Patent, Fig. 22; col. 53:50-57). A defendant may argue this disclosure limits the term to an architecture with these specific characteristics.

• The Term: "serial router"

  • Context and Importance: This term, used in conjunction with "serial gateway," defines the mechanism for directing communications within the storage device. Its scope is central to the infringement analysis for both patents.
  • Intrinsic Evidence for a Broader Interpretation: Claim 20 of the '535 Patent describes the router's function broadly as "to manage the serial control-related data," which could encompass any logic that directs data traffic ('535 Patent, col. 11:39-44).
  • Intrinsic Evidence for a Narrower Interpretation: The specification links the router's function to "using the device identification to direct the asserted command to the targeted device" ('535 Patent, col. 12:39-42). This suggests a specific function tied to decoding device IDs, which could support a narrower construction than a generic data switch.

VI. Other Allegations

• Indirect Infringement: The complaint alleges that Defendant induces infringement by "providing these products to end-users for use in an infringing manner" (Compl. ¶19, 28). The allegations are based on the sale of products that are alleged to inherently infringe when used as intended.
• Willful Infringement: The complaint supports its willfulness claim by alleging that Defendant had pre-suit knowledge of the asserted patent families. It alleges that "Pegatron cited directly to the '535 Patent family" and "'411 Patent family" during the prosecution of its own foreign patent, TWI696914B, which was published on June 21, 2020 (Compl. p. 6 n.1, p. 8 n.2).

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

• A central issue will be one of evidentiary proof: Can the Plaintiff provide sufficient technical evidence to demonstrate that the internal controller architecture of the accused third-party hard drives performs the specific functions of the claimed "serial gateway" and "serial router," particularly for the means-plus-function limitations of the '411 Patent?
• A key legal question will be one of infringement liability: Do the infringement allegations, which focus on the internal workings of components sourced from third parties (WD, HGST), establish a valid claim for direct infringement against Defendant Pegatron for its role in assembling and selling the end-product servers?
• The case will also likely turn on a question of knowledge and intent: How will the court view the allegation that Pegatron cited the asserted patent families in its own foreign prosecution? This fact may be pivotal in establishing the knowledge required for both indirect and willful infringement.
