Zenpayroll v. Uniloc USA Inc
I. Executive Summary and Procedural Information
- Parties & Counsel:
- Plaintiff: ZenPayroll, Inc., dba Gusto (Delaware)
- Defendant: Uniloc USA, Inc. (Texas) and Uniloc Luxembourg, S.A. (Luxembourg)
- Plaintiff’s Counsel: Fenwick & West LLP
- Case Identification: 4:17-cv-03105, N.D. Cal., 05/30/2017
- Venue Allegations: Plaintiff Gusto filed this declaratory judgment action in the Northern District of California, asserting venue is proper because Defendant Uniloc USA allegedly conducts substantial business in the district, and Defendant Uniloc Luxembourg is an alien entity. This filing followed a patent infringement suit filed by Uniloc against Gusto in the Eastern District of Texas, which Gusto contends is an improper venue under the Supreme Court's recent TC Heartland decision.
- Core Dispute: Plaintiff seeks a declaratory judgment that its payroll, benefits, and human resources software platform does not infringe three of Defendant’s patents concerning the management and distribution of application programs on a network.
- Technical Context: The patents relate to client-server architectures from the late 1990s for centrally managing, configuring, and deploying software applications to users across a heterogeneous network.
- Key Procedural History: Uniloc filed an infringement action against Gusto in the Eastern District of of Texas on May 9, 2017. Eight days prior to Gusto filing this declaratory judgment action, the Supreme Court issued its decision in TC Heartland, which significantly altered the standard for patent venue. An Inter Partes Review (IPR) was also instituted against U.S. Patent No. 6,510,466, resulting in the cancellation of several claims.

II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 6,324,578 - "Methods, Systems and Computer Program Products for Management of Configurable Application Programs on a Network," issued Nov. 27, 2001
The Invention Explained
- Problem Addressed: The patent describes the difficulty of managing software in distributed computer networks where users may access applications from various different client workstations, each with potentially different hardware and software configurations. This "roaming" makes it hard to maintain a consistent and personalized user experience ('578 Patent, col. 1:44-58, col. 2:12-24).
- The Patented Solution: The invention proposes a centralized "on-demand" server that stores and manages applications. For each application, it uses two components: an "application launcher" distributed to the client and a "configuration manager" used by an administrator. When a user initiates the launcher, it communicates the user's identity to the server, which then executes the application using a combination of administrator-set preferences (e.g., security settings) and the specific user's stored personal preferences (e.g., screen layout), providing a seamless experience regardless of the client device ('578 Patent, Abstract; col. 3:51-col. 4:6). The process flow is illustrated in Figure 2 of the patent ('578 Patent, Fig. 2).
- Technical Importance: This approach aimed to solve the "user mobility" problem by decoupling user-specific application settings from the local client machine and managing them centrally.
Key Claims at a Glance
- The complaint asserts non-infringement of "one or more claims" of the '578 patent (Compl. ¶25). Independent claim 1 is representative of the patented method.
- Essential elements of Independent Claim 1 include:
- installing an application program having a plurality of configurable preferences and a plurality of authorized users on a server coupled to the network;
- distributing an application launcher program associated with the application program to a client coupled to the network;
- obtaining a user set of the plurality of configurable preferences associated with one of the plurality of authorized users executing the application launcher program;
- obtaining an administrator set of the plurality of configurable preferences from an administrator; and
- executing the application program using the obtained user set and the obtained administrator set of the plurality of configurable preferences responsive to a request from the one of the plurality of authorized users.
U.S. Patent No. 7,069,293 - "Methods, Systems and Computer Program Products for Distribution of Application Programs to a Target Station on a Network," issued Jun. 27, 2006
The Invention Explained
- Problem Addressed: The patent identifies challenges in deploying new or updated software across a network to multiple servers or client stations, a process that was often manual and error-prone ('293 Patent, col. 2:48-58).
- The Patented Solution: The invention describes a method for automated software distribution from a central network management server to a "target station" (such as an on-demand server). The method involves preparing a "file packet" that contains the application program and a segment configured to automatically initiate registration of the application on the target station. This allows a single, automated command to distribute and install the software across multiple target servers, making it available to end-users ('293 Patent, Abstract; col. 5:35-49).
- Technical Importance: The technology provided a framework for centralized, "end-to-end" software deployment, aiming to reduce administrative overhead and ensure consistency across a network.
Key Claims at a Glance
- The complaint asserts non-infringement of "one or more claims" of the '293 patent (Compl. ¶31). Independent claim 1 is representative of the patented method.
- Essential elements of Independent Claim 1 include:
- providing an application program to be distributed to the network management server;
- specifying a source directory and a target directory for distribution of the application program;
- preparing a file packet associated with the application program and including a segment configured to initiate registration operations for the application program at the target on-demand server; and
- distributing the file packet to the target on-demand server to make the application program available for use by a user at a client.
Multi-Patent Capsule
- Patent Identification: U.S. Patent No. 6,510,466, "Methods, Systems and Computer Program Products for Centralized Management of Application Programs on a Network," issued Jan. 21, 2003.
- Technology Synopsis: This patent addresses centrally managing user access to network applications to support user mobility. The invention describes a server that responds to a user login by establishing a "user desktop interface" (e.g., via a web browser) which presents the user with icons for only those applications they are authorized to use ('466 Patent, Abstract; col. 3:25-38). An Inter Partes Review (IPR2017-01315) resulted in the cancellation of claims 1, 2, and 7-9 ('466 Patent, Inter Partes Review Certificate).
- Asserted Claims: The complaint alleges infringement of "one or more claims" (Compl. ¶37).
- Accused Features: The complaint accuses Gusto's general "technology" without specifying features (Compl. ¶¶C, 38).
III. The Accused Instrumentality
- Product Identification: Plaintiff's "payroll, benefits, and human-resources services" and the associated "software" platform (Compl. ¶11).
- Functionality and Market Context: The complaint describes the accused instrumentality in general terms as software that "makes complicated, impersonal business tasks simple and personal" for thousands of companies (Compl. ¶¶11-12). It does not provide specific technical details about the architecture or operation of the Gusto platform. No probative visual evidence provided in complaint.
IV. Analysis of Infringement Allegations
The complaint does not provide specific infringement allegations or a mapping of the accused product to the patent claims. To the contrary, it incorporates by reference an underlying complaint from a separate case (filed by Uniloc in E.D. Tex.) and alleges that the referenced complaint is "facially deficient" and "does not even purport to map the Gusto product to all elements of any asserted claim" (Compl. ¶¶25, 31, 37). As the provided declaratory judgment complaint only contains denials of infringement, a claim chart summary cannot be constructed.
- Identified Points of Contention:
- Scope Questions: A primary point of contention will likely be whether the claim terms from the patents, which describe a late-1990s client-server environment, can be construed to read on a modern, cloud-based Software-as-a-Service (SaaS) platform. For instance, does accessing a web-based application dashboard constitute receiving a "distributed... application launcher program" as required by the '578 patent?
- Technical Questions: A key technical question will be whether the Gusto platform performs the specific steps recited in the claims. For example, does Gusto's system prepare and distribute a discrete "file packet" for application deployment in the manner claimed by the '293 patent, or does it use modern, continuous integration/continuous deployment (CI/CD) pipelines that are technically distinct?
V. Key Claim Terms for Construction
For U.S. Patent No. 6,324,578:
- The Term: "application launcher program" (from Claim 1)
- Context and Importance: This term is central to the invention's architecture, as it is the component "distributed" to the client to initiate a request to the server. The case may turn on whether this term is limited to a distinct, executable file or can encompass a modern web link or a script executed within a browser.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The specification suggests the launcher may be an "applet" and that its function can be initiated by requesting a "URL which points to the location of the applet to be executed," which may support an argument that it covers browser-based actions ('578 Patent, col. 8:10-18).
- Evidence for a Narrower Interpretation: Claim 1 requires "distributing an application launcher program... to a client." This language, combined with descriptions of distributing file packets, could support an argument that a physically distinct software object must be transferred to the client machine, rather than simply accessing a remote resource via a URL ('578 Patent, col. 7:55-58, Fig. 2).
For U.S. Patent No. 7,069,293:
- The Term: "file packet" (from Claim 1)
- Context and Importance: The claim requires "preparing a file packet" and "distributing the file packet." The definition will determine if modern software deployment artifacts, such as container images or code repositories, fall within the claim scope. Practitioners may focus on this term to distinguish between the patent's described distribution model and the accused platform's architecture.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The patent states the packet includes the program and a "segment configured to initiate registration operations," which could be argued to cover any modern bundle of code and its associated configuration or metadata files ('293 Patent, col. 5:35-44).
- Evidence for a Narrower Interpretation: The detailed description and figures refer to a "custom file package set up task" within a specific environment (Tivoli Management Environment), suggesting the "file packet" may be a specific, structured object tied to that era's deployment technology, not a generic term for any software bundle ('293 Patent, Fig. 9A, col. 18:35-41).
VI. Other Allegations
- Indirect Infringement: Gusto affirmatively seeks a declaratory judgment that it does not contribute to or induce infringement of any claim of the patents-in-suit (Compl. ¶¶26, 32, 38). The complaint does not contain factual allegations regarding inducement or contribution, as its purpose is to deny liability.
VII. Analyst’s Conclusion: Key Questions for the Case
- A primary issue will be one of venue and procedure: Will the dispute be resolved in the Northern District of California, as Gusto requests based on TC Heartland, or in the Eastern District of Texas, where Uniloc first filed suit? The resolution of this question will dictate the early trajectory of the case.
- A central substantive issue will be one of technological translation: Can the claim language, rooted in the paradigms of late-1990s client-server software distribution (e.g., "application launcher programs," "file packets"), be construed to cover the architecture of a modern, cloud-native, browser-based SaaS platform?
- For the '466 patent specifically, a dispositive question will be the impact of claim cancellation: Given that an Inter Partes Review has already invalidated key claims, the focus will be on whether any remaining asserted claims are valid and distinct enough from the cancelled claims to support an infringement case.
