Via Tech Inc v. Adobe Inc
I. Executive Summary and Procedural Information
- Parties & Counsel:
- Plaintiff: ViaTech Technologies, Inc. (Delaware)
- Defendant: Adobe Inc. (Delaware)
- Plaintiff’s Counsel: Ashby & Geddes; Bunsow De Mory LLP
- Case Identification: 1:22-cv-00598, D. Del., 05/03/2022
- Venue Allegations: Venue is alleged to be proper in the District of Delaware because Defendant is incorporated there, has a registered agent in the state, and has committed alleged acts of infringement within the district. The complaint also notes that a prior related case was transferred to the district upon Defendant's motion.
- Core Dispute: Plaintiff alleges that Defendant’s software activation technologies, used to protect its software products from piracy, infringe a patent related to an embedded license control mechanism for digital content.
- Technical Context: The technology concerns digital rights management (DRM) for software, a critical field for protecting intellectual property and revenue streams in an era of internet-based distribution.
- Key Procedural History: The complaint discloses a prior, pending lawsuit between the same parties involving the same patent (ViaTech I, Case No. 1-20-cv-00358-RGA). This second suit was filed after Defendant moved to dismiss ViaTech I on the grounds that Plaintiff lacked standing at the time the initial suit was filed. This action appears intended to cure the alleged standing defect and preserve Plaintiff's right to damages. The complaint also alleges that Defendant had knowledge of the patent-in-suit as early as 2011 due to its own patent prosecution activities and received a detailed notice letter with infringement claim charts in 2015.

II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 6,920,567 - "System and Embedded License Control Mechanism for the Creation and Distribution of Digital Content Files and Enforcement of Licensed Use of the Digital Content Files"
The Invention Explained
- Problem Addressed: The patent describes the challenge of distributing and controlling the licensed use of digital content files, such as computer programs or data. Prior art methods were noted as being cumbersome (e.g., relying on hardware dongles), inflexible (e.g., tied to enterprise-wide systems), or employing protection mechanisms that were separate from the licensed program and thus potentially easier to bypass (’567 Patent, col. 1:26-3:52).
- The Patented Solution: The invention discloses a digital content file that integrates the content with an "embedded file access control mechanism" (FACM). This FACM contains both the logic for enforcing a license (a "license functions mechanism") and a local "dynamic license database" to store the specific terms of that license. By embedding the control system directly within the distributed file, the invention aims to create a more secure and self-contained method for enforcing license terms (’567 Patent, Abstract; Fig. 1A; col. 10:25-46).
- Technical Importance: This architecture represented a move toward more portable and robust software protection that was not dependent on physical media or separate, loosely-coupled enforcement programs, a key development for the secure distribution of software over the internet (Compl. ¶¶ 14, 17).
Key Claims at a Glance
- The complaint asserts infringement of at least independent claim 1 (’567 Patent, col. 41:1-42:5).
- The essential elements of independent claim 1 are:
- A digital content file, comprising a digital content and an embedded file access control mechanism.
- The embedded file access control mechanism includes a license functions mechanism.
- The license functions mechanism comprises:
- A license monitor and control mechanism that communicates with a dynamic license database and monitors the use of the digital content to ensure compliance with the license.
- A license control utility that provides for communication between the user's system and an external system to communicate license definition information, and which includes a graphical user interface.
- A dynamic license database associated with the file for storing license information and information controlling the operations of the file access control mechanism.
- The complaint reserves the right to assert other claims, and notes that its 2015 notice letter to Defendant identified infringement of claims 1, 2, 3, 4, 5, 7, 13, 14, and 15 (Compl. ¶¶ 30, 40).
III. The Accused Instrumentality
Product Identification
- The complaint accuses Adobe's "Software Activation Technologies" (Compl. ¶21). These technologies are allegedly implemented in numerous Adobe products, including Adobe Creative Cloud (CC) 2019 and earlier, Adobe Document Cloud (DC) 2019 and earlier, Adobe Acrobat 2017, Adobe Creative Suite (CS) 6, and Adobe Acrobat XI (Compl. ¶¶ 27, 41).
Functionality and Market Context
- The accused technologies require users to perform a mandatory "activation" process to use the full features of Adobe's software (Compl. ¶¶ 22, 24). This process validates a user's license to prevent unauthorized use and sends license-related information to Adobe's servers (Compl. ¶23).
- A key technical component is identified as the "Adobe AMT Library" (e.g., "amtlib.dll" on Windows), which the complaint alleges is an embedded mechanism for controlling access and ensuring compliance with licensing policies (Compl. ¶27).
- The system is alleged to store license information locally on the user's machine, for example in the Windows Credential Storage, MacOS Keychain, or specific file directories, which enables the software to function offline for a defined grace period (e.g., 30-99 days) (Compl. ¶¶ 25, 43). This local storage and offline functionality is presented as evidence that the control mechanism is locally operative and embedded (Compl. ¶25).

’567 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| a digital content file including a digital content, and an embedded file access control mechanism | Adobe Product files (e.g., installer files and installed applications) are alleged to be "digital content files" that contain an embedded file access control mechanism. | ¶41 | col. 4:58-62 |
| a license monitor and control mechanism communicating with a dynamic license database and monitoring use of the digital content | The Adobe Product files, via components like the AMT Library, allegedly communicate with a local "dynamic license database" to monitor use and determine if it complies with the license. | ¶43 | col. 10:35-40 |
| a license control utility providing communications between a user system and an external system to communicate license definition information...including a graphical user interface | The AMT Library is alleged to provide for communications with Adobe's external licensing and activation servers. The GUI is allegedly provided via dialog boxes for sign-in, trial period information, and activation options. | ¶¶44, 45 | col. 11:1-14 |
| a dynamic license database...for storing information controlling operations of the file access control mechanism and license information | Local data stores on the user's machine (e.g., Windows Credential Storage, MacOS Keychain, or SLStore/SLCache directories) are alleged to function as the dynamic license database, storing license credentials and information. | ¶¶43, 46 | col. 10:33-35 |
- Identified Points of Contention:
- Scope Questions: A central dispute may concern whether Adobe's architecture constitutes an "embedded" mechanism as claimed. The defense could argue that the system, comprising a combination of a software library ("amtlib.dll"), OS-level data stores, and remote cloud servers, is distinct from the digital content file itself and therefore not "embedded" in the manner described by the patent.
- Technical Questions: The analysis will likely focus on whether the information communicated by the accused system qualifies as "license definition information" as required by the claim, or if it is merely for validation. Further, there is a question of whether a general-purpose OS feature, such as the MacOS Keychain, can be considered a "dynamic license database associated with the file access control mechanism" as specifically contemplated by the patent.
V. Key Claim Terms for Construction
The Term: "embedded file access control mechanism"
Context and Importance: This term is the technological core of the patent. The outcome of the case may depend on whether Adobe's distributed activation system, which relies on components both inside and outside the application file, falls within the scope of this term. Practitioners may focus on this term because its construction will determine whether a system with external dependencies (like Adobe's) can infringe a claim directed to an "embedded" feature.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The specification describes embodiments where the mechanism is "functionally embedded," for example, by linking an executable file to a separate but essential "wrapper" dynamic link library (Wdll). This suggests the term may not require a single, monolithic file but rather a tight, functional integration where the content cannot operate without the control mechanism ('567 Patent, col. 16:6-34; Fig. 1B).
- Evidence for a Narrower Interpretation: The patent's abstract and Figure 1A depict the "FACM" (File Access Control Mechanism) as a component located physically inside the boundary of the "DCF" (Digital Content File). This could support a narrower construction requiring the entire control mechanism to be self-contained within the digital content file itself ('567 Patent, Abstract; Fig. 1A).
The Term: "dynamic license database"
Context and Importance: The plaintiff's theory identifies general operating system features (like the Windows Credential Storage) as the claimed "database." The construction of this term is critical to determining if using such generic OS components meets the claim limitation.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: Claim 1 requires the database to be "associated with the digital content file for storing information controlling operations." This functional language does not explicitly restrict the database's form or location, potentially allowing it to read on any local data store used for the recited purpose ('567 Patent, col. 41:20-24).
- Evidence for a Narrower Interpretation: Figure 1A shows the "Dldb" (Dynamic License Database) as a distinct component of the "FACM," which is in turn embedded in the file. This may support an interpretation that the database must be a specific, dedicated component of the access control mechanism, not a general-purpose OS service that also stores other, unrelated data ('567 Patent, Fig. 1A).
VI. Other Allegations
- Indirect Infringement: The complaint alleges induced infringement, stating that Adobe encourages and instructs end-users to install and activate its software with the knowledge that doing so constitutes infringement. Activation is presented as a mandatory, non-optional step required for the products to function properly (Compl. ¶¶ 48, 51).
- Willful Infringement: Willfulness is alleged based on extensive pre-suit knowledge. The complaint asserts that Adobe was aware of the ’567 Patent as early as 2011, when it was cited as prior art during the prosecution of Adobe's own patent applications (Compl. ¶¶ 32-35). Furthermore, it is alleged that ViaTech sent Adobe a detailed notice letter with claim charts in April 2015, which Adobe did not respond to, and that Adobe subsequently "doubled down" on its infringing activities (Compl. ¶¶ 29-31, 36).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of architectural scope: Can the claim term "embedded file access control mechanism," which the patent illustrates as an integral part of a digital file, be construed to read on Adobe's system, which distributes control functions across a local software library, operating system services, and remote servers?
- A key evidentiary question will be one of functional mapping: Does the combination of Adobe's AMT Library and local data storage perform the specific, multi-part functions recited in Claim 1—particularly the communication of "license definition information"—or is there a material difference in its technical operation compared to the patented invention?
- A significant procedural question will be the impact of the prior litigation: How will the standing dispute in ViaTech I and the filing of this parallel action affect the potential damages period, discovery, and overall case strategy, particularly in light of the plaintiff’s stated intent to seek consolidation?
