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

U.S. Patent No. 9,305,143 - “Broadcasting of Electronic Documents Preserving Copyright and Permitting Private Copying”

Issued: April 5, 2016

The Invention Explained

• Problem Addressed: The patent addresses the problem that electronic documents, unlike physical books, can be "easily and infinitely copyable to the detriment of the legitimate copyrights," while existing DRM solutions were often too restrictive, preventing legitimate users from making private copies for use on their own various devices (Compl. ¶ 1; ’143 Patent, col. 1:28-44).
• The Patented Solution: The invention proposes a system where each purchased electronic document is generated with a "unique identifier" and an embedded "supervision agent." Before the document can be viewed, this agent must contact a remote "control server" over a network to verify the user's "controlled consultation rights" (e.g., viewing permissions, expiration dates). Because all private copies of the document share the same unique identifier, the control server treats them as a single entity, thus enabling private copying while preventing unauthorized distribution and use (’143 Patent, Abstract; col. 2:1-24; FIG. 1).
• Technical Importance: This approach sought to balance the competing interests of copyright holders and consumers by creating a technical means to enforce usage rights without completely prohibiting the user convenience of private copying, a central challenge in the digital content industry (’143 Patent, col. 1:40-44).

Key Claims at a Glance

• The complaint asserts infringement of at least Claim 1 (Compl. ¶ 11).
• Independent Claim 1 recites a multi-step method, the essential elements of which include:
  • Accessing an "order server" to handle a customer order.
  • The "order server" sending order information (work reference, customer info, digital rights) to a "delivery server".
  • The "delivery server" creating a delivery record with a "unique identifier" to control the work.
  • The "order server" sending the customer a URL link containing the "unique identifier".
  • Upon activation of the URL, the "delivery server" generating a specific copy of the document containing the "unique identifier" and a "supervision agent".
  • The "delivery server" sending "controlled information" to a "control server".
  • A verification step where the "supervision agent" on the customer's device connects to the "control server", sends a query with the "unique identifier", and receives an authorization or refusal in response, which either allows or prohibits consultation of the document.
• The complaint reserves the right to assert infringement of other claims (Compl. ¶ 15).

III. The Accused Instrumentality

Product Identification

The accused instrumentalities are the "Adobe eBook Platform and its Adobe InDesign CC Software, Adobe Content Server 6 Software, the Adobe Reader Mobile 11 Software Development Kit (SDK), and the Adobe Digital Editions Software" (Compl. ¶ 11).

Functionality and Market Context

The complaint alleges that the accused products form a comprehensive ecosystem for protecting and distributing eBooks. The system allegedly involves publishers using Adobe InDesign to create content and Adobe Content Server (ACS) to encrypt the files and manage distribution rights (Compl. ¶ 25, p. 9). When a consumer purchases an eBook, they allegedly receive a .acsm file, which the complaint characterizes as a license. The Adobe Digital Editions (ADE) software on the user's device then uses this file to communicate with Adobe's servers, verify the user's rights via their Adobe ID, and download the encrypted eBook for viewing (Compl. ¶ 25, p. 14). The complaint presents a diagram from Adobe's materials illustrating the platform's workflow, which is divided into "Authoring," "Content Protection," and "Delivery" stages (Compl. p. 9).

IV. Analysis of Infringement Allegations

’143 Patent Infringement Allegations

Identified Points of Contention

• Scope Questions: A central question may be whether the accused system's .acsm file, which appears to be a separate license file, meets the claim limitation of a "supervision agent" that is "integrated with each copy of the document" (’143 Patent, col. 5:32-33). The defense may argue that the claim requires the agent to be embedded within the document file itself, not a separate precursor file.
• Technical Questions: The complaint equates the user's "Adobe ID" with the claimed "unique identifier of the ordered document copy" (Compl. ¶ 25, p. 16; ’143 Patent, col. 6:15). A potential dispute is whether a user-specific identifier (Adobe ID) is technically equivalent to a document-copy-specific identifier as recited in the claim, which is intended to allow all private copies of a single purchased document to be treated as one entity by the control server (’143 Patent, col. 2:15-19).

V. Key Claim Terms for Construction

"supervision agent"

• Context and Importance: This term is the active component that enforces the claimed access control. The plaintiff's infringement theory appears to depend on mapping this term to the accused system's .acsm license file. Practitioners may focus on this term because its structural relationship to the "document" is a potential point of dispute.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The patent functionally describes the agent as "a program which authorizes or refuses the consultation of said copy, by means of sending a query" (col. 5:33-36). This functional language could support an interpretation that is not strictly limited by its structure.
  • Evidence for a Narrower Interpretation: The specification states, "A supervision agent is integrated with each copy of the document generated" and that a program "integrates with the copy a supervision agent" (col. 5:32-33; col. 5:20-21). This language may support a narrower construction requiring the agent to be a component embedded within the data structure of the document itself.

"unique identifier of the copy ordered"

• Context and Importance: This identifier is the lynchpin for tracking and controlling access to a specific purchased document and its private copies. The validity of the plaintiff's infringement read, which maps this term to a user's "Adobe ID," will depend on its construction.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The patent's goal is to make a document and all its copies "be seen as a single document by the control server" (’143 Patent, col. 2:17-19). Any identifier that achieves this unique, copy-centric tracking function might be argued to fall within the claim's scope.
  • Evidence for a Narrower Interpretation: The claim language consistently ties the identifier to the "copy ordered" or "work ordered" (col. 6:15-16, 21-22). This could support a narrower definition that requires the identifier to be specific to the document instance itself, rather than a general identifier for the user who purchased it.

VI. Other Allegations

Indirect Infringement

The complaint alleges induced infringement under 35 U.S.C. § 271(b). It asserts that Adobe intends for its customers to infringe by providing the integrated Accused Instrumentalities and "providing instructions for using the methods" in their "normal and customary way" (Compl. ¶¶ 16, 18).

Willful Infringement

The complaint alleges that Adobe "has been willfully blind to the possibility that its inducing acts would cause infringement" (Compl. ¶ 19). Knowledge of the patent is alleged to exist "at least as of the date this lawsuit was filed," which may support a claim for post-filing willful infringement or enhanced damages (Compl. ¶ 17).

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

• A core issue will be one of structural definition: does the accused system's use of a separate .acsm license file, which initiates a download, meet the claim requirement of a "supervision agent" that is described in the patent as being "integrated with" the document copy itself?
• A key evidentiary question will be one of technical mapping: can the user-specific "Adobe ID" used in the accused system be shown to function as the claimed "unique identifier of the ordered document copy," which the patent specification appears to link to the digital work itself rather than the user's account?
• The resolution of the infringement analysis will likely depend on whether the court adopts a broader, functional interpretation of the key claim terms or a narrower one based on the specific architecture described in the patent's embodiments.
