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

U.S. Patent No. 6,330,549 - "Protected Shareware"

The Invention Explained

  • Problem Addressed: The patent addresses the challenge of protecting computer software from unauthorized use and ensuring supplier compensation, particularly within a "shareware" distribution model where programs are freely copied and distributed ('549 Patent, col. 1:11-20, 1:50-55). It sought a more effective alternative to easily defeated copy-protection schemes or inconvenient physical hardware "dongles" ('549 Patent, col. 1:36-49).
  • The Patented Solution: The invention proposes a system where "protective code" embedded within a software program controls its functionality. This code inhibits certain features until it receives a digitally signed "authorization message" from a trusted entity, such as a billing agency. The software program itself holds a "public checking key" which it uses to verify the authenticity of the authorization message before enabling the protected features ('549 Patent, Abstract; col. 3:24-48). The system also includes an "integrity self-check" routine to ensure the protective code itself has not been disabled or altered ('549 Patent, col. 4:1-8).
  • Technical Importance: This cryptographic approach provided a flexible framework for digital rights management, allowing for business models like free trials or metered usage while maintaining a mechanism to enforce payment for continued or extended use ('549 Patent, col. 8:58-65).

Key Claims at a Glance

  • The complaint asserts "one or more claims" of the '549 Patent (Compl. ¶9). Independent claim 1 is representative of the core invention.
  • Independent Claim 1 (Method):
    • Inhibiting a functional feature of a computer program on a user computer until it receives an authorization message digitally signed by an authorized party with a secret key.
    • Providing the program's protective code with access to the corresponding public checking key.
    • Running an integrity self-check to confirm the program is in an "anticipated state."
    • Communicating the authorization message to the user computer.
    • Applying the public key to authenticate the message.
    • Enabling the functional feature if the message is authenticated and the integrity check passes.
  • The complaint reserves the right to modify its infringement theories and assert other claims as discovery progresses (Compl. ¶15).

III. The Accused Instrumentality

Product Identification

Functionality and Market Context

  • The complaint identifies the accused instrumentality as the Prudential website, alleging it is used in connection with the "sales and offering for sale of its products and services" (Compl. ¶12). However, the complaint does not provide sufficient detail for analysis of the website's specific technical functionality that is alleged to infringe. The infringement theory is contained in a referenced "Exhibit B," which was not filed with the complaint and is not part of the public record based on the provided documents.

IV. Analysis of Infringement Allegations

The complaint alleges infringement but does not include the referenced claim chart exhibit (Exhibit B) that would detail its infringement theory. The complaint’s narrative states that infringement occurs through Defendant’s "making and using (including testing) its Accused Product with the sales and offering for sale of its products and services" (Compl. ¶12). Without Exhibit B, the specific mechanisms within the prudential.com website that are alleged to practice each claim element are not identified in the provided documents.

No probative visual evidence provided in complaint.

  • Identified Points of Contention:
    • Scope Questions: A primary issue will be whether the patent's claims, written in the context of distributable "shareware" and "executable computer programs" intended for a "user's host computer" ('549 Patent, col. 1:7, col. 4:65-66), can be construed to read on the operation of a modern, server-side financial services website. The dispute may center on whether server-side code controlling access to website content for a visitor constitutes an "embedded protective code" in a "computer program" on a "user computer" as the patent describes.
    • Technical Questions: A key evidentiary question will be what technical process in the operation of the Prudential website Plaintiff alleges constitutes the "digitally signed... authorization message" required by the claims. Further, the complaint provides no facts identifying what might function as the patent's "public checking key" or the "integrity self-check" within the accused website's architecture.

V. Key Claim Terms for Construction

  • The Term: "embedded protective code"

    • Context and Importance: The applicability of the patent to a website hinges on this term. The defense may argue that code operating on a remote server is not "embedded" in a "computer program" running on a "user computer" in the manner contemplated by the patent.
    • Intrinsic Evidence for a Broader Interpretation: The specification does not explicitly define "embedded," which could leave room for an argument that any code integral to the program's function, whether client-side or server-side, qualifies.
    • Intrinsic Evidence for a Narrower Interpretation: The patent repeatedly discusses "protected shareware" and "executable computer programs" ('549 Patent, col. 1:1-8), and Figure 1 depicts a "PROTECTED PROGRAM" (11) residing on "USER A's COMPUTER" distinct from remote entities. This context suggests code residing locally on the end-user's machine.

  • The Term: "authorization message"

    • Context and Importance: Plaintiff must identify a specific data transmission within the accused system that meets the claim's requirements. The nature of this "message" is central to the infringement analysis.
    • Intrinsic Evidence for a Broader Interpretation: The term itself is general. An argument could be made that any data packet that grants or denies access to a feature, such as an authentication token or session cookie, could qualify as an "authorization message."
    • Intrinsic Evidence for a Narrower Interpretation: The patent specifies the message is "digitally signed by an authorized party using a secret signing key" ('549 Patent, col. 8:51-53). The examples in the patent describe a formal security protocol involving a "billing agency" and a "billing computer," suggesting a more complex and secure transaction than standard web protocols for session management ('549 Patent, Fig. 1).

VI. Other Allegations

  • Indirect Infringement: The complaint does not allege indirect infringement.
  • Willful Infringement: Willfulness is alleged based on Defendant’s knowledge of the '549 Patent gained from the service of the complaint itself (Compl. ¶16). This establishes a basis for seeking enhanced damages for any infringement that occurs post-filing.

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

  • A core issue will be one of technological applicability: can the patent's claims, which are rooted in the technical context of protecting distributable "shareware" programs running on a user's local computer in the late 1990s, be plausibly applied to the architecture of a modern, server-based commercial website? The case may turn on whether terms like "computer program" and "embedded protective code" can be construed to cover the server-side logic of the accused website.
  • A second central question will be one of evidentiary mapping: assuming the claim terms can be broadly construed, can the Plaintiff produce evidence identifying specific components and processes within the prudential.com infrastructure that perform the cryptographic functions required by the claims, such as the generation and verification of a "digitally signed... authorization message" using a public/private key pair? The complaint itself provides no factual allegations on this point.
