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

U.S. Patent No. 11,516,080 - "Using virtual networking devices and routing information to associate network addresses with computing nodes"

Issued November 29, 2022

The Invention Explained

  • Problem Addressed: The patent addresses the increasing complexity of provisioning, administering, and managing large-scale computing resources in data centers, noting the lack of a well-understood, routine, and conventional way to manage such networks effectively and securely. (Compl. ¶71).
  • The Patented Solution: The invention provides a method for creating and managing distinct virtual computer networks for different clients, overlaid on a shared physical substrate network. The system uses a "virtual peering router" to manage interconnections and route traffic between these separate virtual networks, enabling them to communicate without requiring physical reconfiguration of the underlying network. (Compl. ¶70, ¶138). This allows for dynamic configuration of network topology based on routing information received from computing nodes. (’080 Patent, col. 4:32-56).
  • Technical Importance: This approach allows for flexible, secure, and scalable multi-tenancy in a cloud environment, where different customers can operate isolated virtual networks on shared physical infrastructure. (Compl. ¶72).

Key Claims at a Glance

  • The complaint asserts independent claim 1. (Compl. ¶137).
  • Claim 1 recites a method performed by a configurable network service, comprising the essential elements of:
    • Receiving first configuration information for a first virtual computer network for a first client, indicating a first range of network addresses.
    • Providing the first virtual computer network overlaid on a substrate network.
    • Assigning a network address from the first range to a node in the first virtual network.
    • Receiving second configuration information for a second virtual computer network for a second client.
    • Providing the second virtual computer network overlaid on the substrate network.
    • Assigning a network address from the first range to a node in the first virtual network.

U.S. Patent No. 11,425,194 - "Dynamically modifying a cluster of computing nodes used for distributed execution of a program"

Issued August 23, 2022

The Invention Explained

  • Problem Addressed: As data centers grew in scale, managing physical computing resources became increasingly complicated. Programs could either consume more resources than allocated, creating bottlenecks, or fail to execute if insufficient resources were available. (’194 Patent, col. 1:46-49).
  • The Patented Solution: The invention provides a method for dynamically managing the resources for a distributed program. A user provides instructions specifying an initial number of virtual machines (VMs) and rules for how to modify that number based on "resource utilization metrics." The system then monitors the program's resource use and, if a predefined threshold is exceeded, automatically modifies the quantity of VMs by adding more, allocating physical resources to them while the program is still running. (Compl. ¶88, ¶91, ¶166).
  • Technical Importance: This technology, often called "autoscaling," is a core feature of cloud computing that allows applications to handle variable loads efficiently and cost-effectively without manual intervention. (Compl. ¶93).

Key Claims at a Glance

  • The complaint asserts independent claim 1. (Compl. ¶165).
  • Claim 1 recites a computer-implemented method, comprising the essential elements of:
    • Receiving instructions from a user to execute a program using a specified configuration, which includes a first number of VMs, a maximum number of VMs, and instructions on how to modify the number of VMs based on a resource utilization threshold.
    • Selecting and initiating execution of the program on a group of VMs based on the first number.
    • Monitoring a resource utilization of the group of VMs.
    • Determining, based on the utilization exceeding the threshold, a second, greater number of VMs to use.
    • Modifying the quantity of VMs by adding one or more additional VMs to the group while execution is ongoing, and allocating computing resources from physical systems to the new VMs.
  • The complaint reserves the right to assert additional claims. (Compl. ¶163).

IV. Analysis of Infringement Allegations

'11,516,080 Infringement Allegations

Claim Element (from Independent Claim 1) Alleged Infringing Functionality Complaint Citation Patent Citation
receiving first configuration information for a first virtual computer network of computing nodes to be provided for a first client, wherein the first configuration information indicates a first range of network addresses... The Nuage Networks VSP includes a Virtualized Services Directory (VSD) component that allows configuration of a virtual computer network via a VSD Architect tool, which receives a range of network addresses as input. ¶141-142 col. 4:57-5:9
providing the first virtual computer network to the first client according to the first configuration information, wherein the first virtual computer network is overlaid on a substrate network of the configurable network service The Nuage Networks VSP implements Nuage Networks Virtualized Network Services (VNS) which are "based on an overlay model that uses any IP network to provide underlay connectivity between sites." ¶143-144 col. 1:12-14
providing a virtual peering router configured to manage an interconnection between the first virtual computer network and the second virtual computer network The Nuage Networks VSP includes a "Nuage Networks NSG-BR (border router)" that allegedly "extends seamless connectivity between disparate networks" and provides gateway functionality. ¶152-153 col. 12:23-40
routing, using the virtual peering router, network traffic from the computing nodes of the first virtual computer network to the computing nodes of the second virtual computer network over the substrate network The NSG-BR border router is alleged to route network traffic between untrusted partner networks and a core enterprise network, connecting disparate networks. ¶154-155 col. 2:23-40

An annotated screenshot from a Nokia technical brief shows a user interface for defining a "New Address Range" for a network. (Compl. p. 56). Another diagram illustrates the interconnection between an "Enterprise Trusted Network" and a "Partner Untrusted Network" via the Virtual Services Platform. (Compl. p. 63).

  • Identified Points of Contention:
    • Scope Questions: A central question may be whether the accused "Nuage Networks NSG-BR (border router)" (Compl. ¶153) meets the claim limitation of a "virtual peering router." The analysis could turn on whether the function of connecting an "untrusted" external network to a "trusted" internal network is equivalent to "peering" between two distinct virtual networks, potentially belonging to different clients as suggested by the claim language ("first client," "second client").
    • Technical Questions: The complaint alleges the VSP's "service chaining" provides an "interconnection between the first and second configured virtual computer networks." (Compl. ¶150). A technical question will be whether this service chaining functionality, which sequences network functions, performs the specific "routing" function required of the claimed "virtual peering router."

'11,425,194 Infringement Allegations

Claim Element (from Independent Claim 1) Alleged Infringing Functionality Complaint Citation Patent Citation
receiving... instructions from a first user to execute a program using specified configuration information, the specified configuration information including a first number of virtual machines (VMs) to use to execute the program and a set of instructions specifying how to modify a number of VMs... based on resource utilization metrics... The Nokia CloudBand Application Manager (CBAM) allows a "VNF network" to be configured using a VNF Descriptor package, which consists of OpenStack Heat templates defining VNF specifications, including the number of VMs. ¶170-174 col. 2:56-3:4
the set of instructions specifying a resource utilization threshold The CBAM allegedly supports "VNF threshold policies and policy templates." ¶175-176 col. 19:60-20:9
monitoring... a resource utilization of the group of VMs, wherein the resource utilization is based on a measured amount of a resource used by the group of VMs The CBAM allegedly allows monitoring of VNFs using a "threshold policy" that monitors a set of pre-defined KPIs to define when an application indicates an overload, underload, or healing condition. ¶181-182 col. 4:14-38
modifying... a quantity of VMs in the group of VMs for use in further execution... wherein the modifying includes adding one or more additional VMs... while the execution of the program is ongoing... The CBAM allegedly supports a "Virtual Machine Manager (VMM)" that allows "automatic scale-out and automatic healing" that "automatically increases the processing capacity of the VMM." ¶186-187 col. 34:1-9

A screenshot from Nokia documentation describes deploying a VSR instance using an OpenStack HEAT template, which specifies resources including the "type and number of VMs." (Compl. p. 71). Another screenshot illustrates a "VNF threshold policy status" dashboard, showing monitoring of resource usage. (Compl. p. 76).

  • Identified Points of Contention:
    • Scope Questions: The claims are directed to managing clusters of "virtual machines (VMs)." The complaint's evidence focuses on Nokia's management of "Virtual Network Functions (VNFs)." (Compl. ¶172). A key legal question will be whether a VNF, which is a virtualized network service, constitutes a "program" as that term is used in the patent, and whether the virtual resources used for VNF instantiation are equivalent to the claimed "group of multiple computing VMs."
    • Technical Questions: Claim 1 requires modifying the quantity of VMs by adding one or more additional VMs. The complaint points to Nokia's "automatic scale-out" that "increases the processing capacity." (Compl. ¶187). A factual dispute may arise over whether this "increase in capacity" is always achieved by adding distinct, additional VMs, as required by the claim, or if it could be achieved by other means, such as increasing the resources allocated to existing VMs.

V. Key Claim Terms for Construction

For U.S. Patent No. 11,516,080

  • The Term: "virtual peering router"
  • Context and Importance: This term is central to the claimed method of connecting two distinct virtual networks. The complaint's infringement theory hinges on equating Nokia's "NSG-BR (border router)" with this claimed element. (Compl. ¶153). Practitioners may focus on whether "peering" implies a relationship between equals, as is common in network terminology, or if it can broadly cover a gateway function between different types of networks (e.g., trusted and untrusted).
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The claim describes the router as "configured to manage an interconnection between the first virtual computer network and the second virtual computer network," language that does not inherently limit the nature of the two networks beyond their being distinct. (’080 Patent, claim 1).
    • Evidence for a Narrower Interpretation: The use of "first client" and "second client" in the claim suggests the two virtual networks may belong to separate, independent entities. (Compl. ¶138). A court could find that "peering" in this context implies a connection between two similar entities, rather than a gateway from an internal enterprise network to an external partner network.

For U.S. Patent No. 11,425,194

  • The Term: "modifying... a quantity of VMs in the group of VMs... by adding one or more additional VMs"
  • Context and Importance: This term defines the specific mechanism of autoscaling. The complaint accuses Nokia's "automatic scale-out" feature. (Compl. ¶187). The dispute will likely focus on whether Nokia's accused feature performs this exact modification step, or if "increasing... capacity" can be achieved in ways not covered by the claim language.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The patent specification describes dynamic modification in broad terms, including "adding and/or removing computing nodes from the cluster that is executing the program, modifying the amount of computing resources that are available," which could be argued to encompass various forms of scaling. (’194 Patent, col. 2:41-45).
    • Evidence for a Narrower Interpretation: The claim language is specific: "modifying... a quantity... wherein the modifying includes adding one or more additional VMs." (’194 Patent, claim 1). This explicit language could support a narrow construction that requires the instantiation of new, distinct VM instances, as opposed to merely allocating more CPU or memory to existing VMs.

VI. Other Allegations

  • Indirect Infringement: For each asserted patent, the complaint alleges active inducement under 35 U.S.C. § 271(b), stating that Nokia provides "directions, technical support, guides, marketing materials, instruction manuals, and/or other information that encourage and facilitate infringing use." (Compl. ¶158, ¶190). It further alleges contributory infringement under 35 U.S.C. § 271(c), asserting that the accused products "include non-standard software, knowing the same to be especially made or especially adapted for use in an infringement" of the patents. (Compl. ¶161, ¶193).
  • Willful Infringement: The complaint alleges that "Nokia is and has been on notice of the infringement of the [asserted patents] at least as of the time Amazon filed and provided notice of this Complaint." (Compl. ¶156, ¶188). This establishes a basis for willfulness based on alleged post-suit knowledge.

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

  • A central issue will be one of definitional scope: can networking concepts from Nokia's accused products, such as "border router" and "service chaining," be construed to meet the specific claim term "virtual peering router" from the ’080 patent, which facilitates connection between networks of a "first client" and a "second client"?
  • A key evidentiary question will be one of technological equivalence: does Nokia’s system for managing the lifecycle of Virtual Network Functions (VNFs) operate in the same way as the claimed method of dynamically modifying a quantity of Virtual Machines (VMs) based on resource utilization metrics, as recited in the ’194 patent?
  • The case presents a broader strategic question of market evolution and appropriation: Did Defendant's recent entry into the cloud services market involve the adoption of foundational architectural principles that were developed and patented by Plaintiff during the formative years of the cloud industry?
