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

U.S. Patent No. 7,065,555 - “System and Method Related to Generating and Tracking an Email Campaign,” Issued June 20, 2006

The Invention Explained

  • Problem Addressed: The patent describes prior art email campaigns as suffering from "difficulties in locating a pool of relevant individuals to be contacted" and in "tailoring the large number of required email messages to the individuals for more effective contact" (Compl. ¶32; ’555 Patent, col. 1:26-33).
  • The Patented Solution: The invention proposes an automated system where an "email campaign generator" creates an "email campaign template" from a database of targets. An "email campaign engine" then uses this template to generate and send a "custom email" to each individual target, and a "campaign tracker" monitors the responses (Compl. ¶32; ’555 Patent, col. 1:49-55). The complaint includes Figure 9 from the patent, which illustrates this sequence of receiving a database, generating a template, sending customized emails, and tracking them (Compl. p. 10, Fig. 9).
  • Technical Importance: The technology aimed to automate and scale personalized mass-email marketing, improving campaign efficiency and effectiveness over generic broadcast emails (Compl. ¶32; ’555 Patent, col. 1:26-33).

Key Claims at a Glance

  • The complaint focuses on independent claim 1 (Compl. ¶31).
  • Essential elements of claim 1 include:
    • receiving an email target database;
    • generating an email campaign template, which comprises (a) generating a message template and (b) generating a configuration file with insertable data for each target;
    • sending to each of the at least one email target a corresponding custom email formed from the email campaign template; and
    • tracking the custom email sent to each of the at least one email target (Compl. ¶36).

U.S. Patent No. 7,979,057 - “Third-Party Provider Method and System,” Issued July 12, 2011

The Invention Explained

  • Problem Addressed: The patent family specification describes traditional paper coupons as inefficient and prone to fraud, and notes that prior electronic systems were proprietary and tied to specific hardware at the point of selection, limiting their utility (’057 Patent, col. 2:42-65, col. 3:1-14).
  • The Patented Solution: The invention describes a method for processing "negotiable economic credits" (e.g., coupons, awards) on a wireless handheld device like a Personal Digital Assistant (PDA). The system allows a user to receive a credit over a wireless network, store it in the device's local memory, and subsequently retrieve and transfer it at a retail point-of-sale, thereby creating a portable, non-proprietary electronic wallet for such credits (’057 Patent, Abstract, col. 3:26-44).
  • Technical Importance: The technology sought to leverage the growing popularity of PDAs to create a more efficient, secure, and consumer-friendly system for redeeming coupons and other economic credits than paper-based or store-specific electronic methods (’057 Patent, col. 3:45-53).

Key Claims at a Glance

  • The complaint focuses on independent claim 1 (Compl. ¶58).
  • Essential elements of claim 1 include:
    • storing a filter in a memory of a hand held device;
    • receiving at least one negotiable economic credit from a wireless network at the hand held device based on the stored filter;
    • storing the at least one negotiable economic credit in the memory of the hand held device;
    • retrieving the at least one negotiable economic credit; and
    • transferring the at least one negotiable economic credit via the wireless network (Compl. ¶60).

III. The Accused Instrumentality

Product Identification

The complaint identifies three categories of accused instrumentalities: (1) The AAdvantage Program enrollment process on AA.com (the "Enrollment Process"); (2) American's iOS and Android mobile applications ("American's Applications"); and (3) American's website and webservers (Compl. ¶¶ 31, 55, 86).

Functionality and Market Context

  • The Enrollment Process is a web-based form where prospective members enter personal information to join the AAdvantage loyalty program. Upon submission, the system sends the user a personalized "Welcome Email" (Compl. ¶35).
  • American's Applications are mobile apps that allow users to manage travel and make payments using various forms of value, such as "American Airlines Coupons, American Airlines AAdvantage Rewards, American Airlines Payment Wallet, [and] American Airlines Gift Cards" (Compl. ¶58). The complaint includes screenshots of the applications' listings on the Apple App Store and Google Play store (Compl. ¶¶ 121-126). This screenshot from the app store describes the app's functionality, including managing AAdvantage account details and booking flights (Compl. p. 19).
  • American's website and webservers are accused of receiving requests for webpages that include a "locale identifier value" to serve localized content (Compl. ¶86).

IV. Analysis of Infringement Allegations

’555 Patent Infringement Allegations

Claim Element (from Independent Claim 1) Alleged Infringing Functionality Complaint Citation Patent Citation
(1) receiving an email target database; The system allegedly receives a database of email targets when users submit their personal information through the AAdvantage enrollment web form. ¶35 col. 5:6-12
(2) generating an email campaign template related to at least one email target... wherein step (2) comprises: (a) generating a message template, and (b) generating a configuration file... The system allegedly generates a template and a configuration file containing the user's data (e.g., name) to personalize the subsequent welcome email. ¶35 col. 5:13-34
(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; and The system sends a "Welcome Email" to the user, which is customized with personal information (e.g., "Hello JOHN.") allegedly formed from the template. ¶35 col. 6:66-7:9
(4) tracking the custom email sent to each of the at least one email target. The complaint does not provide sufficient detail for analysis of this element. --- col. 7:10-12

Identified Points of Contention

  • Scope Questions: A primary issue is definitional: does an automated process that sends a single, transactional email to an individual upon enrollment constitute an "email campaign" as contemplated by the patent? American argues it does not, contrasting it with a process that sends emails to "each" target within a pre-existing "database" (Compl. ¶37).
  • Technical Questions: A key factual question is whether a "message template" is "generat[ed]" after receiving the email target database, as required by the claim's sequence. American alleges its Welcome Email design "preexists any member receiving it," suggesting a static template is used rather than one generated in response to an enrollment (Compl. ¶38).

’057 Patent Infringement Allegations

Claim Element (from Independent Claim 1) Alleged Infringing Functionality Complaint Citation Patent Citation
storing a filter in a memory of a hand held device... The complaint does not provide sufficient detail for analysis of this element. --- col. 4:22-29
receiving at least one negotiable economic credit from the wireless network at the hand held device based on the stored filter; The mobile applications are used to receive credits such as coupons, AAdvantage Rewards, and gift cards. ¶58 col. 4:30-33
storing the at least one negotiable economic credit in the memory of the hand held device; The system allegedly stores these negotiable credits on the user's smartphone. American explicitly denies this functionality. ¶58, ¶61 col. 4:34-36
retrieving the at least one negotiable economic credit; and The system allegedly retrieves the locally stored credit for use in a transaction. ¶58, ¶62 col. 4:37-38
transferring the at least one negotiable economic credit via the wireless network. The system allegedly transfers the retrieved credit from the handheld device to complete a payment. ¶58, ¶62 col. 4:39-41

Identified Points of Contention

  • Technical Questions: The central dispute is factual and technical: Do "American's Applications" actually "store" negotiable credits in the local "memory of the hand held device"? American's position is that they do not store credits on the device but merely provide an interface to access credits stored on American's remote servers (Compl. ¶61). This raises the question of whether temporary data caching could be construed as "storing."
  • Scope Questions: The dispute may turn on the scope of "storing...in the memory." Does this require persistent, long-term storage of the full credit value on the device, as the patent's focus on PDAs as self-contained repositories suggests, or could it cover transient data or pointers to server-side accounts?

V. Key Claim Terms for Construction

For the ’555 Patent

  • The Term: "email campaign"
  • Context and Importance: The applicability of claim 1 hinges on whether the accused "Enrollment Process" qualifies as an "email campaign." If sending individual, triggered transactional emails falls outside the scope of this term, the non-infringement argument may be significantly strengthened. Practitioners may focus on this term as it appears to be the primary basis for American's non-infringement position for the '555 patent family.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The specification defines an email campaign as "[a] system for sending email to a number of email targets" for "purposes such as marketing, information acquisition, or otherwise" ('555 Patent, col. 1:22-25). The phrase "or otherwise" could support a broad interpretation beyond traditional marketing blasts.
    • Evidence for a Narrower Interpretation: The background section frames the problem solved by the invention in the context of mass marketing, citing "difficulties in locating a pool of relevant individuals" and tailoring a "large number of required email messages" ('555 Patent, col. 1:26-33). This language may support a narrower construction limited to broadcasting messages to a pre-compiled list, not one-off transactional messages.

For the ’057 Patent

  • The Term: "storing the at least one negotiable economic credit in the memory of the hand held device"
  • Context and Importance: This limitation is the core of American's non-infringement defense for the entire '057 patent family. The factual question of whether the accused applications perform this "storing" function will be dispositive. Practitioners may focus on this term because it represents a potential fundamental mismatch between the claimed technology and the accused client-server architecture.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The term "storing" is not explicitly defined and could arguably encompass temporary data caching necessary for the app to function or to display a user's account balance.
    • Evidence for a Narrower Interpretation: The patent repeatedly describes the invention in the context of PDAs, which were often used for offline data storage. The claim structure, which requires steps of receiving, storing, retrieving, and transferring from the device memory, suggests a self-contained process where the credit itself resides locally on the device, rather than existing as an entry on a remote server that is merely accessed by the device.

VI. Other Allegations

The complaint does not contain specific factual allegations supporting indirect or willful infringement theories; rather, it seeks a declaratory judgment that American Airlines does not infringe directly, indirectly, or by equivalence.

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

  • A core issue will be one of definitional scope: can the term "email campaign," rooted in the patent’s description of mass marketing to a "pool of individuals," be construed to cover a series of automated, individually-triggered transactional emails like the accused AAdvantage welcome messages?
  • A key evidentiary question will be one of technical operation: do the accused mobile applications perform the claimed step of "storing" a "negotiable economic credit" in the local "memory of the hand held device," or do they operate as a client-server system that merely accesses credits stored remotely, presenting a potential mismatch with the patent's claimed architecture?
  • A third question of definitional scope will concern whether general localization data used by American's website satisfies the '736 patent's specific claim requirement for a "locale identifier value," which the specification defines with particularity as a "32-bit numeric value in hexadecimal" associated with a specific server type.
