II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 6,249,868 - "METHOD AND SYSTEM FOR EMBEDDED, AUTOMATED, COMPONENT-LEVEL CONTROL OF COMPUTER SYSTEMS AND OTHER COMPLEX SYSTEMS" (Issued June 19, 2001)
The Invention Explained
- Problem Addressed: The patent's background section describes the inadequacy of conventional security measures for personal computers ("PCs"), such as physical locks and software passwords, which can be circumvented by determined thieves, rendering stolen equipment usable (’868 Patent, col. 1:21–2:34).
- The Patented Solution: The invention proposes embedding hardware or software "agents" directly into system components. These agents intercept communications and require continuous authorization from a remote server to permit the component to function. Authorization is maintained through periodic "handshake operations." If a device is stolen and disconnected from the server, authorization expires, and the agent disables the component, rendering it inoperable (’868 Patent, Abstract; col. 3:51-65). Figure 3 of the patent illustrates this architecture, showing a remote server (318) communicating with an embedded agent (302) via a client (310) on the host system (’868 Patent, Fig. 3).
- Technical Importance: This system shifts security from a user-possessed key or password, which can be lost or stolen, to a persistent, remote authorization model designed to make equipment worthless to a thief after disconnection from the network (’868 Patent, col. 3:35-43).
Key Claims at a Glance
- The complaint asserts independent claims 1 and 44 (Compl. ¶¶ 14-16).
- Claim 1 (a system claim) includes these essential elements:
- A computer system having a device;
- An agent embedded in the device that enables operation when authorized and disables operation when not authorized;
- A server coupled to the agent that authorizes it by exchanging messages that compose a handshake operation.
- Claim 44 (a control system claim) includes these essential elements:
- An agent embedded in a component of a multi-component system that enables or disables the component's operation based on authorization;
- A server coupled to the agent that authorizes it via a handshake operation composed of exchanged messages.
U.S. Patent No. 6,594,765 - "METHOD AND SYSTEM FOR EMBEDDED, AUTOMATED, COMPONENT-LEVEL CONTROL OF COMPUTER SYSTEMS AND OTHER COMPLEX SYSTEMS" (Issued July 15, 2003)
The Invention Explained
- Problem Addressed: As a continuation-in-part of the ’868 Patent, the ’765 Patent addresses the same fundamental security problem but expands the application of the technology beyond PCs to a broader range of complex systems (’765 Patent, col. 3:41-50).
- The Patented Solution: The patented solution remains centered on the remote server-embedded agent architecture, as shown in Figure 3. However, the specification explicitly contemplates applications in other domains, including "automobiles, firearms, home entertainment systems," and introduces concepts like authorization based on proximity to a server or location within a defined physical space (’765 Patent, Fig. 3; col. 4:31-48).
- Technical Importance: The patent extends the concept of component-level remote authorization to mobile and non-traditional computer systems, including vehicles, which were becoming increasingly computerized at the time of the invention (’765 Patent, col. 4:50-53).
Key Claims at a Glance
- The complaint asserts independent claim 1 and dependent claims 2 and 9 (Compl. ¶¶ 14-16).
- Claim 1 (a system claim) includes these essential elements:
- An automotive system including a device;
- An agent embedded in the device that enables or disables operation based on authorization;
- A server coupled to the agent that authorizes it through a handshake operation.
- Dependent claim 2 specifies the automotive system is an automobile or truck.
- Dependent claim 9 adds a timer within the agent that is used to request re-authorization from the server.
III. The Accused Instrumentality
Product Identification
- The accused instrumentalities are Hyundai vehicles equipped with two distinct systems: (1) the Hyundai Blue Link Service and (2) the vehicle's Immobilizer System and associated key fobs (Compl. ¶16).
Functionality and Market Context
- Hyundai Blue Link Service: This is a telematics service that, according to the complaint, allows for remote control of vehicle functions. The allegedly infringing features include "Remote Vehicle Start, Stolen Vehicle Slowdown, and Vehicle Immobilization" (Compl. ¶14). The complaint alleges these features work by having a remote "Hyundai server" communicate with a "computer system (embedded agent) installed in the vehicle" to enable or disable its operation (Compl. ¶14).
- Immobilizer System: This system is alleged to prevent unauthorized vehicle use by controlling the ignition. The complaint characterizes the key fob as a "server" that communicates with the "Immobilizer System (embedded agent)" in the vehicle. Through a series of messages, the two components allegedly "mutually authenticate one another" to authorize the vehicle to start (Compl. ¶15).

- Identified Points of Contention:
- Scope Questions: While the ’765 patent explicitly claims an "automotive system," the ’868 patent is primarily directed to "personal computers." A question for the court may be whether the term "computer system" in the ’868 patent can be construed to cover the distributed electronic architecture of a vehicle, even though the specification provides vehicles as one example of "other complex systems" (’868 Patent, col. 3:29-30). A further question is whether a local, handheld key fob can be considered a "server" as that term is used in the patents, which describe it as a component running on a "remote server computer" (’868 Patent, col. 3:60-61).
- Technical Questions: The patents describe a "handshake operation" involving a specific multi-message exchange process (e.g., AUTHORIZE, CONFIRM, OK) (’868 Patent, Figs. 7A-F). The complaint alleges the accused systems perform a "handshake operation" but describes it generally as a "series of secure message exchanges" or "mutual authentication" (Compl. ¶¶ 14-15). A central technical question will be whether the accused products' communication protocols perform the specific functions required by the claims as informed by the specification.
V. Key Claim Terms for Construction
The Term: "handshake operation"
- Context and Importance: This term is the core of the claimed authorization mechanism. Infringement for both accused systems will depend heavily on whether their authentication protocols meet the definition of this term. Practitioners may focus on this term because the complaint's general description of authentication raises the question of a technical mismatch with the specific process detailed in the patents.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The claims themselves define the term broadly as "exchanging a number of messages... that together compose a handshake operation" (’868 Patent, col. 32:62-64). This could support an argument that any multi-step authorization process is covered.
- Evidence for a Narrower Interpretation: The detailed description and Figures 7A-7F provide a specific, three-part message sequence (AUTHORIZE, CONFIRM AUTHORIZATION, OK) as the exemplary handshake (’868 Patent, col. 4:51-62). This detailed embodiment may be used to argue for a narrower construction limited to such a multi-step confirmation and password-exchange protocol.
The Term: "server"
- Context and Importance: The complaint's allegation that a key fob is a "server" makes the construction of this term critical for the infringement theory against the Immobilizer System (Compl. ¶15). The outcome may determine whether that system can infringe.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The patent does not provide a standalone definition of "server." A party could argue it should be given its plain and ordinary meaning, which might encompass any device that provides a service (e.g., authorization) to another device.
- Evidence for a Narrower Interpretation: The patent's abstract and detailed description consistently describe the server as a component "running on a remote computer" that is coupled to the agent via a "communications medium" like a LAN or WAN (’868 Patent, Abstract; col. 7:12-16). Figure 3 depicts the server as a distinct "remote server computer" (318), separate from the system containing the agent. This may support an interpretation that requires the server to be a remote, networked computer, not a local, handheld device like a key fob.
VI. Other Allegations
- Indirect Infringement: The complaint alleges both induced and contributory infringement (Compl. ¶13). Inducement is based on allegations that Hyundai provides "user guides and other sales-related materials" that instruct customers on using the infringing features (Compl. ¶17). Contributory infringement is based on the allegation that the accused components have "no substantial non-infringing uses" and are especially adapted for use in an infringing manner (Compl. ¶19).
- Willful Infringement: While not explicitly pleading willfulness, the complaint alleges pre-suit knowledge of the patents as of October 2, 2015, based on a series of notice letters to which Hyundai allegedly did not respond (Compl. ¶11). The prayer for relief requests that the court declare the case "exceptional" and award attorney's fees under 35 U.S.C. § 285 (Compl. p. 7, ¶e). These allegations could support a later claim for enhanced damages.
VII. Analyst’s Conclusion: Key Questions for the Case
This case will likely present several key questions for judicial determination, focusing on the intersection of claim scope and the specific operation of the accused automotive technologies.
- A core issue will be one of definitional scope: can the term "server," as used in the patents' context of a remote, networked computer, be construed to cover a local, handheld vehicle key fob as alleged for the Immobilizer System?
- A central evidentiary question will be one of technical function: does the "mutual authentication" protocol between the Hyundai key fob and vehicle, or the secure messaging of the Blue Link service, perform the specific, multi-step "handshake operation" that the patent specifications describe as the mechanism for authorization?
- A foundational question for the ’868 patent will be one of technological scope: can the claims, which are framed around a "computer system" and primarily described in the context of a personal computer, be interpreted to read on the distinct electronic architecture of a modern vehicle?
