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

U.S. Patent No. 7,363,416 - Computer System Utilizing Multiple Computer Modules with Password Protection

  • Issued: April 22, 2008 (the ’416 Patent)

The Invention Explained

  • Problem Addressed: The patent’s background describes the inefficiency and cost of consumers owning separate desktop and portable computers, which involves duplicated components and cumbersome data transfer. It also notes that conventional dual-CPU systems can suffer from performance bottlenecks when sharing resources like memory and disk drives (’416 Patent, col. 1:18–col. 2:67).
  • The Patented Solution: The invention proposes a modular computer system where multiple, self-contained "computer modules"—each with its own dedicated processor, memory, and storage—can operate independently within a shared peripheral console (’416 Patent, Abstract). This architecture, illustrated in Figure 1 of the patent, allows for enhanced capabilities such as fault tolerance, backup, and dual processing while sharing peripherals like monitors and keyboards (’416 Patent, col. 4:10–29).
  • Technical Importance: This modular approach provided a framework for increasing computing density and reliability, anticipating the architectural principles that would become fundamental to blade servers and other high-density computing systems (Compl. ¶21).

Key Claims at a Glance

  • The complaint does not identify the specific claims asserted against the accused products (Compl. ¶25).

U.S. Patent No. 7,676,624 - Multiple Module Computer System and Method Including Differential Signal Channel Comprising Unidirectional Serial Bit Channels

  • Issued: March 9, 2010 (the ’624 Patent)

The Invention Explained

  • Problem Addressed: Traditional parallel interfaces for connecting computer components, such as the PCI bus, are not "cable friendly." They require a large number of conductive lines and high-pin-count connectors, making them bulky, expensive, and susceptible to noise over distances required in a modular system (’624 Patent, col. 3:3–65).
  • The Patented Solution: The invention describes an interface that bridges two computer buses by encoding parallel signals (e.g., from a PCI bus) into a high-speed serial bitstream. This stream is transmitted over a differential signal channel, such as a Low Voltage Differential Signal (LVDS) channel, which requires significantly fewer physical wires and pins. The signals are then decoded back into parallel format at the receiving end (’624 Patent, Abstract). This enables a robust, cable-friendly, high-bandwidth connection between a computer module and a peripheral console (’624 Patent, col. 5:4–24).
  • Technical Importance: This high-speed serial interconnect technology is a key enabler for the physical realization of modular and blade server architectures, allowing independent computer modules to be reliably connected and disconnected from a central chassis (Compl. ¶21).

Key Claims at a Glance

U.S. Patent No. 7,818,487 - Multiple Module Computer System and Method Using Differential Signal Channel Including Unidirectional, Serial Bit Channels

  • Issued: October 19, 2010 (the ’487 Patent)

Technology Synopsis

This patent appears to be a continuation of the technology in the ’624 Patent, focusing on a method and system for interfacing computer modules using high-speed, unidirectional serial bit channels. It addresses the technical challenge of creating reliable, high-bandwidth, and physically compact connections necessary for modular computing environments (’487 Patent, Abstract; col. 3:3-65).

Asserted Claims

One or more claims of the ’487 Patent (Compl. ¶43).

Accused Features

Alcatel-Lucent products utilizing the ATCA Hardware Platform or ATCA V2 Platform (Compl. ¶43).

U.S. Patent No. 8,041,873 - Multiple Module Computer System and Method Including Differential Signal Channel Comprising Unidirectional Serial Bit Channels to Transmit Encoded Peripheral Component Interconnect Bus Transaction Data

  • Issued: October 18, 2011 (the ’873 Patent)

Technology Synopsis

This patent further details the technology for converting parallel bus transaction data, specifically from a Peripheral Component Interconnect (PCI) bus, into an encoded serial format for transmission over a differential signal channel. This encoding and transmission method is designed to overcome the physical limitations of parallel buses in a modular system architecture (’873 Patent, Abstract; col. 3:3-65). The complaint notes this patent survived reexamination at the USPTO (Compl. ¶18).

Asserted Claims

One or more claims of the ’873 Patent (Compl. ¶52).

Accused Features

U.S. Patent No. RE41,294 - Password Protected Modular Computer Method and Device

  • Issued: April 27, 2010 (the ’294 Patent)

Technology Synopsis

This patent discloses methods and devices for securing a removable computer module with a password. The security system can prevent unauthorized use by requiring a password stored in a programmable memory device (e.g., flash memory) within the module itself. This provides a persistent security layer tied to the physical hardware module, protecting it even when moved between different consoles (’294 Patent, Abstract; col. 5:50-67).

Asserted Claims

One or more claims of the ’294 Patent (Compl. ¶61).

Accused Features

Alcatel-Lucent products utilizing the ATCA Hardware Platform or ATCA V2 Platform (Compl. ¶61).

III. The Accused Instrumentality

Product Identification

The accused instrumentalities are Alcatel-Lucent's modular computing products, including but not limited to those utilizing its ATCA Hardware Platform or ATCA V2 Platform, with the Alcatel-Lucent 5060 Media Gateway Controller identified as a specific example (Compl. ¶22).

Functionality and Market Context

The complaint describes the accused products as components of "modular computer systems," which house multiple computers in a single chassis to provide more processing power in less space, simplify cabling, and reduce power consumption (Compl. ¶21). ATCA (Advanced Telecom Computing Architecture) is an industry standard for such modular platforms, widely used in telecommunications. The complaint alleges that these modular systems have become "extremely popular" due to customer demand for increased computing power and lower ownership costs (Compl. ¶21).

IV. Analysis of Infringement Allegations

The complaint does not identify specific claims asserted from the Patents-in-Suit, nor does it provide a detailed, element-by-element infringement analysis. The infringement allegations are made generally, stating that Alcatel-Lucent's products are "covered by one or more claims" of each patent (Compl. ¶¶25, 34, 43, 52, 61, 70, 79, 88, 97). Without identification of asserted claims, a detailed infringement analysis or identification of specific points of contention is not possible based on the complaint's contents.

No probative visual evidence provided in complaint.

V. Key Claim Terms for Construction

The complaint does not provide sufficient detail for analysis of key claim terms, as no specific claims from the asserted patents have been identified.

VI. Other Allegations

Indirect Infringement

For each of the nine patents, the complaint alleges both induced and contributory infringement. The allegations are based on Alcatel-Lucent providing the accused products to end-users and resellers along with "user guides and product documentation that instruct" them to use the products in an infringing manner (e.g., Compl. ¶¶27, 36, 45).

Willful Infringement

Willfulness is alleged based on pre-suit knowledge of the patents. The complaint asserts that ACQIS provided Alcatel-Lucent with a certified letter on May 3, 2013, identifying eight of the nine patents-in-suit and referencing the prior successful litigation against IBM involving related patents (Compl. ¶104). Knowledge of the ninth patent is alleged to have been provided upon service of the initial complaint on September 11, 2013 (Compl. ¶104). The complaint alleges that Alcatel-Lucent's continued infringement after these notices was "objectively-reckless" (Compl. ¶105).

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

  • A threshold procedural issue will be one of pleading sufficiency: whether the complaint's generalized allegations, which fail to identify asserted claims or map claim elements to accused features, satisfy the plausibility standard for patent infringement claims set forth by the Supreme Court in Twombly and Iqbal.
  • A central technical question will be one of claim scope versus industry standards: once claims are identified, the dispute will likely focus on whether the patented inventions, developed in the context of general-purpose modular computing, can be construed to cover products built on the specific, standardized requirements of the Advanced Telecom Computing Architecture (ATCA) platform.
  • A key issue for damages and willfulness will be the impact of pre-suit notice: the court will examine whether the detailed notice letter sent by ACQIS, which included references to prior successful litigation and patent reexaminations, created a duty for Alcatel-Lucent to investigate and avoid infringement, potentially supporting a finding of willfulness.
