Case Timeline

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

U.S. Patent No. 11,416,887 - "Methods and Apparatus for Mobile Device Messaging-Based Communications Using Custom-Generated Deeplinks and Based on the Hyper Text Transfer Protocol (HTTP)"

The Invention Explained

• Problem Addressed: The patent's background describes prior art mobile sign-up and purchase methods as "time-consuming and burdensome," involving many user inputs (e.g., clicks or screen taps) that often caused users to abandon the process before completion Compl. ¶37 '887 Patent, col. 1:42-47
• The Patented Solution: The invention provides a server-based system to streamline this process. A server sends an "integration tag" to be included in a client's webpage. When a user on a mobile device interacts with a promotional message on that page, the server defines and sends a specific Uniform Resource Identifier (URI), or "deeplink," to the device. This URI automatically transitions the user from the first application (e.g., a web browser) to a messaging application with a text message pre-populated with a recipient number and a custom message body. Upon the user sending that message, the server enrolls the device in the promotion without requiring any further information from the user Compl. ¶40 '887 Patent, abstract '887 Patent, col. 3:9-4:12
• Technical Importance: This "two-tap" approach is designed to reduce user friction in mobile marketing sign-ups, which may increase subscriber conversion rates for e-commerce brands Compl. ¶7 Compl. ¶30

Key Claims at a Glance

• The complaint asserts infringement of at least independent claim 1 Compl. ¶77
• The essential elements of Claim 1 include a click-to-text server configured to:
  • Send an "integration tag" to a client server to be served with a webpage;
  • Define and send a "uniform resource identifier (URI)" to the mobile device that "deeplinks" to a messaging application;
  • The URI causes the mobile device to "(1) automatically transition" from the first application to the messaging application and "(2) automatically populate a custom message";
  • "receive the custom message" at the click-to-text server after the user sends it; and
  • "enroll the mobile device in a promotion" based on receiving the message and "without receiving any additional information".
• The complaint states that Postscript infringes "one or more claims" of the '887 Patent, reserving the right to assert other claims Compl. ¶76

U.S. Patent No. 11,416,897 - "Methods and Apparatus for Mobile Device Messaging-Based Communications Using Custom-Generated Deeplinks and Based on the Hyper Text Transfer Protocol (HTTP)"

The Invention Explained

• Problem Addressed: Like its family member the '887 Patent, this patent addresses the high-friction, multi-step nature of conventional mobile sign-up processes that lead to user drop-off Compl. ¶37 '897 Patent, col. 1:30-47
• The Patented Solution: The patent claims a system using means-plus-function language. A server sends "means for displaying an invitation" (e.g., a promotional pop-up) to a user's device. In response to a user interaction, the server sends "means for causing" the device to transition to a messaging app and populate a custom message. After the server receives this custom message, it delivers an "installment" of the subscription service (e.g., the first promotional text) without requiring a separate opt-in communication Compl. ¶125 '897 Patent, abstract '897 Patent, col. 3:53-4:32
• Technical Importance: The invention aims to provide a near-seamless user experience for subscribing to SMS marketing lists, thereby enhancing user engagement and sign-up efficiency Compl. ¶39

Key Claims at a Glance

• The complaint asserts infringement of at least independent claim 15 Compl. ¶125
• The essential elements of Claim 15 include a processor-readable medium with instructions for a server to:
  • Send "means for displaying an invitation to subscribe" to a mobile device via a first application;
  • Send "means for causing (1)" the mobile device to "transition" from the first application to a second, different messaging application and "(2)" the second application to "automatically populate a custom text message";
  • "receive, from the mobile device, the custom text message"; and
  • "deliver an installment" of the subscription service "without receiving an opt-in communication" after receiving the custom message.
• The complaint alleges infringement of "one or more claims," reserving the right to assert others Compl. ¶124

U.S. Patent No. 11,553,074 - "Methods And Apparatus For Dynamic Application Deeplinking At A Mobile Electronic Device"

• Technology Synopsis: This patent, also from the same family, describes a server-side method for mobile subscription. The server defines an "integration tag" for a webpage, receives device identifiers, sends a signal to display a promotional "frame" on the webpage, and receives an indication of user interaction. It then sends a URI that causes the mobile device to switch from the web browser to a text messaging app with a pre-populated message. After receiving the text, the server subscribes the device and delivers a subscription installment without a further opt-in step Compl. ¶174
• Asserted Claims: The complaint asserts infringement of at least independent claim 23 Compl. ¶174
• Accused Features: The allegations target Defendant's "two-touch" SMS marketing sign-up process, which utilizes mobile popups that deeplink to a pre-populated text message for subscribing to a promotional service Compl. ¶54 Compl. ¶173

III. The Accused Instrumentality

Product Identification

The accused instrumentalities are "Postscript's SMS Marketing Platform and Postscript's other offerings and services that integrate with Postscript's SMS Marketing Platform" (collectively, the "Accused Products") Compl. ¶8 Compl. ¶53

Functionality and Market Context

• The complaint alleges the Accused Products provide a "Two-Touch opt-in" feature for e-commerce clients to subscribe mobile users to SMS marketing lists Compl. ¶54 The process is described as a user first tapping a call-to-action (CTA) on a mobile popup, which launches the user's native messaging application with a pre-populated text message Compl. ¶54 Compl. p. 13 The user's second tap sends this message, completing the sign-up Compl. ¶54 Compl. p. 13 A screenshot in the complaint illustrates a user interacting with a "GET 15% OFF COUPON" button on a brand's website, which then opens a new text message with pre-filled content Compl. p. 14 The platform allegedly utilizes API endpoints for deeplinking and for passing user device data to a back-end server Compl. ¶¶69-71 Postscript provides tools for its customers to create and customize these popups, including the associated keywords and confirmation messages Compl. ¶¶56-64 Another screenshot shows the Postscript user interface for creating a "Two Touch popup" and configuring its confirmation message to include a keyword Compl. p. 27
• The complaint positions Defendant Postscript as a "direct competitor of Attentive" in the mobile-signup and mobile-messaging market Compl. ¶8

IV. Analysis of Infringement Allegations

'887 Patent Infringement Allegations

• Identified Points of Contention:
  • Scope Questions: The analysis may focus on whether the combination of Postscript's API endpoints and customer-side popup scripts performs the specific server-side actions of "defining and sending" the URI as required by the claim. A question could be raised as to whether the process is controlled by a single "click-to-text server" as claimed, or if functionality is distributed in a way that falls outside the claim's scope.
  • Technical Questions: The complaint alleges on "information and belief" that Postscript's servers perform certain actions Compl. ¶81 A central evidentiary question will be what technical evidence supports the allegation that Postscript's back-end system architecture maps to the specific steps and components recited in Claim 1.

'897 Patent Infringement Allegations

• Identified Points of Contention:
  • Scope Questions (Means-Plus-Function): As Claim 15 uses "means for" language, its scope is limited to the corresponding structures disclosed in the patent's specification and their equivalents. A primary dispute will likely be whether the architecture of Postscript's Accused Products is structurally equivalent to the "click-to-text server," "processor," and "integrator" modules described in the '897 patent (e.g., '897 Patent, FIG. 1; '897 Patent, col. 5:3-6:65).
  • Technical Questions: A point of contention may be the definition of an "installment of the text messaging subscription service." The defense could argue that the initial automated confirmation message is a transactional reply, not a substantive "installment" of a recurring service, potentially placing it outside the scope of the final claim element.

V. Key Claim Terms for Construction

• The Term: "automatically" ("automatically transition", "automatically populate") (from '887 Patent, Claim 1)

• Context and Importance: This term is central to the claimed "two-tap" efficiency. The degree of automation required by the claim will be critical. If the accused process involves intermediate steps that are not deemed "automatic," infringement might be contested.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The patent specification frames the invention as an improvement over prior art requiring "many user inputs" '887 Patent, col. 1:43-45 This context may support a construction where "automatically" means "without additional substantive user input to achieve the claimed result."
  • Evidence for a Narrower Interpretation: The description of a URI that "is initiated" and causes an application to be "opened" '887 Patent, col. 3:12-16 could support a narrower construction requiring a direct, machine-driven action without any intervening system-level prompts (e.g., an operating system dialog asking for permission to open another app).

• The Term: "installment of the text messaging subscription service" (from '897 Patent, Claim 15)

• Context and Importance: The final step of the asserted claim requires delivering an "installment." Whether the initial welcome message containing a promotional offer qualifies as such will be a key issue. If it is considered merely a confirmation, this element may not be met.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The patent's summary describes a platform for "messaging-based subscriptions and payments" '897 Patent, col. 1:17-19 This may suggest that the very first message delivering value (like a discount) as part of the new subscription relationship constitutes the first "installment."
  • Evidence for a Narrower Interpretation: A party could argue that an "installment" implies one of a series of recurring messages, and that a one-time transactional confirmation message is distinct. The patent, however, does not appear to make this distinction explicitly, referring generally to "promotional messages" (e.g.,'897 Patent, col. 7:35-42).

VI. Other Allegations

• Indirect Infringement: The complaint alleges induced infringement, stating that Defendant encourages its customers to use the Accused Products in an infringing manner through its website, help articles, user guides, and technical support that instruct on implementing the "two-touch" sign-up functionality Compl. ¶¶112-114 Compl. ¶¶161-163 Compl. ¶¶214-216
• Willful Infringement: The complaint makes specific allegations of willful infringement based on pre-suit knowledge. It claims Defendant cited the '887 and '897 Patents in an Information Disclosure Statement submitted to the USPTO on September 21, 2022, during the prosecution of its own patent application Compl. ¶121 Compl. ¶170 Willfulness is also alleged based on a notice letter sent January 24, 2023, and knowledge gained from the filing of the complaint itself Compl. ¶121 Compl. ¶170 Compl. ¶223

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

• A core issue for the '897 patent will be one of structural equivalence: as Claim 15 is drafted in means-plus-function format, the infringement analysis will likely depend on whether Postscript's API-based system is structurally equivalent to the specific "click-to-text server" architecture disclosed in the patent's specification.
• A key legal question will be one of definitional scope: can the term "installment of the... subscription service" be construed to cover the initial automated welcome message that delivers a coupon, or does it require a subsequent, recurring message from the marketing campaign itself?
• A central question for damages will be one of willfulness and intent: given the allegation that Defendant cited the patents-in-suit during its own patent prosecution months before the lawsuit was filed, the case will likely focus heavily on what Defendant knew about the patents and whether its continued activities constitute the sort of egregious conduct that could lead to enhanced damages.
