The website is alleged to use locale-specific identifiers to provide geographically tailored content to users (Compl. ¶137). AutoZone is described as a major automotive parts retailer with over 6,234 stores, suggesting these marketing systems are of significant commercial importance (Compl. ¶12).
IV. Analysis of Infringement Allegations
U.S. Patent No. 7,065,555 Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation | 
|---|---|---|---|
| a method for an email campaign, said method comprising the steps of: (1) receiving an email target database... | AutoZone's Marketing System receives an email target database by, for example, collecting customer information through its "AutoZone Rewards" member signup page. | ¶91 | col. 2:50-52 | 
| (2) generating an email campaign template related to at least one email target in the received email target database... | The system generates an email campaign template related to the user data, such as the personalized "welcome" email sent to new rewards members. | ¶92 | col. 2:52-55 | 
| wherein the step of generating an email campaign template...comprises the step of: (a) generating a message template; and (b) generating a configuration file to contain data related to each of the at least one email target, wherein the data is insertable in the generated message template | AutoZone's system allegedly generates a message template (the body of the email) and a configuration file containing data (e.g., images, text referencing the recipient) that is insertable into the template. | ¶¶93-94 | col. 3:20-30 | 
| (3) sending to each of the at least one email target a corresponding custom email, wherein the custom email is formed from the email campaign template | The system sends a custom email, such as the one depicted in the complaint, to each target, with the email formed from the campaign template. The screenshot of a personalized "Welcome" email is provided as an example of such a custom email (Compl. p. 30). | ¶95 | col. 2:55-58 | 
| and (4) tracking the custom email sent to each of the at least one email target | AutoZone's system tracks the custom emails sent to users, for example through its privacy policy which describes collecting "Device and Website Interaction information" including app usage and interaction information with websites or emails. | ¶96 | col. 2:58-60 | 
- Identified Points of Contention:- Scope Questions: Claim 1 recites generating a specific two-part "email campaign template" structure, comprising a "message template" and a separate "configuration file." A central question may be whether AutoZone's modern, database-driven email marketing system, which dynamically generates personalized content, can be mapped onto this specific claimed architecture from the year 2000. For instance, does a database record queried at the time of sending constitute a "configuration file" as contemplated by the patent?
- Technical Questions: The complaint provides screenshots of the inputs (signup form) and outputs (final email) of the accused system. What evidence does the complaint provide that the intermediate steps of generating a discrete "message template" and a separate "configuration file" are actually performed by the AutoZone Marketing System, as opposed to a different process that achieves a similar result?
 
U.S. Patent No. 7,386,594 Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation | 
|---|---|---|---|
| A method for producing a custom email template at a computing device, said method comprising the steps of: (a) receiving, at the computing device, email addresses for a plurality of target recipients... | AutoZone's email servers receive email addresses for a plurality of target recipients, for example, through the AutoZone Rewards member signup process. | ¶102 | col. 8:1-3 | 
| (b) producing at the computing device, as the custom email template, a configuration file and a message file... | The AutoZone Marketing System's email servers produce a custom email template comprising a configuration file and a message file. | ¶¶103-105 | col. 8:3-5 | 
| wherein the configuration file includes, for each of the plurality of target recipients, data related to the target recipient and a custom uniform resource locator unique to the target recipient | The configuration file allegedly includes data related to each recipient and a custom URL unique to them. | ¶105 | col. 8:6-10 | 
| and wherein the message file includes a textual message for each of the custom email messages and a plurality of custom tags configured to receive, for each target recipient, the data related to the target recipient and an executable link configured to receive the custom uniform resource locator unique to the target recipient | The message file allegedly includes a textual message and custom tags configured to receive the recipient-specific data and a link to receive the unique URL. | ¶¶104-105 | col. 8:11-20 | 
- Identified Points of Contention:- Scope Questions: Similar to the ’555 patent, the dispute may center on whether the terms "configuration file" and "message file" can be construed to read on the components of a modern, integrated email marketing platform. Practitioners may question if these terms require discrete, separable data objects or if they can cover logical constructs within a database-driven system.
- Technical Questions: The infringement allegations in the complaint for the '594 patent are stated at a high level. A key question for discovery will be what technical evidence exists to show that AutoZone's system actually "produces" a "configuration file" and a "message file" as two distinct components of a "custom email template," rather than simply merging data from a database into an email body at the time of sending.
 
V. Key Claim Terms for Construction
- The Term: "email campaign template"- Context and Importance: This term, central to the asserted claims of the '555 and '594 patents, is defined as comprising two distinct components: a "message template" and a "configuration file." The viability of the infringement case depends on whether AutoZone's modern email system can be shown to generate this specific two-part structure. Practitioners may focus on this term because the accused system likely uses a dynamic, database-driven architecture that may not create the discrete, static file-based structures contemplated by the patents from the early 2000s.
- Intrinsic Evidence for Interpretation:- Evidence for a Broader Interpretation: A party might argue that the patent's abstract describes the invention more broadly as a "method and system for generating and tracking an email campaign" ('555 Patent, Abstract), suggesting the specific two-part "template" is merely one embodiment of a broader concept of combining generic content with personalized data.
- Evidence for a Narrower Interpretation: The detailed description explicitly breaks down the process, stating the "email campaign template can be generated by generating a message template, and generating a configuration file" ('555 Patent, col. 2:1-4). Figure 3A visually separates the "Text Message" (320) and ".cfg File" (330) as distinct outputs of the Email Campaign Generator, which may support a narrower construction requiring two identifiable components.
 
 
VI. Other Allegations
- Indirect Infringement: The complaint alleges inducement to infringe the ’057 and ’608 patents (Compl. ¶¶129, 162). The allegations are based on AutoZone instructing and encouraging its customers to use the AutoZone iOS and Android Apps. The complaint asserts that AutoZone knows the acts it induces constitute infringement and that these acts result in direct infringement by its customers (Compl. ¶¶130, 163). The factual basis cited is AutoZone's promotion of the apps on its website and in app stores (Compl. ¶¶131, 164).
- Willful Infringement: The willfulness allegations for all asserted patents are based on alleged pre-suit knowledge. The complaint states that on August 17, 2022, Plaintiff’s counsel sent a letter with a draft of the complaint to AutoZone's General Counsel, expressly identifying the patents-in-suit and the accused products (Compl. ¶20). Plaintiff alleges that AutoZone's continued infringement after this date has been willful (Compl. Prayer for Relief ¶k).
VII. Analyst’s Conclusion: Key Questions for the Case
- A central technical question will be one of architectural equivalence: does AutoZone's modern, database-integrated digital marketing platform create the discrete "email campaign template"—comprising a separate "message template" and "configuration file"—as required by the '555 and '594 patents, or does its architecture for personalizing emails represent a fundamentally different technology that post-dates the claimed invention?
- A key issue for the mobile commerce patents ('057, '519, '608, '529) will be one of definitional scope: can the term "negotiable economic credit," described in the patent in the context of coupons and enterprise awards, be construed to cover the full range of modern digital assets alleged by the plaintiff, including the AutoZone Rewards points and the AutoZone Payment Wallet, within the specific multi-step methods claimed?
- An evidentiary question regarding inducement will be whether the plaintiff can demonstrate that AutoZone possessed the requisite specific intent to encourage infringement by its customers, beyond merely providing and marketing its mobile apps for their intended purposes. The analysis will likely focus on whether the instructions provided by AutoZone direct users to perform the patented methods in a manner that is distinguishable from non-infringing use.
