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

U.S. Patent No. 8,719,101 - "System and method of on-line advertising"

  • Patent Identification: U.S. Patent No. 8,719,101, "System and method of on-line advertising," issued May 6, 2014.

The Invention Explained

  • Problem Addressed: The patent addresses the ineffectiveness of conventional online advertising, where banner ads and unsolicited emails risk being irrelevant or unwanted by the recipient, potentially creating a negative perception of the advertiser (’101 Patent, col. 1:26-37). The patent seeks a method to gather a recipient's contact information and send targeted, requested advertisements through a non-disruptive interaction with a banner ad (’101 Patent, col. 1:38-43).
  • The Patented Solution: The invention is a system where a user can interact with an "interactive element" (e.g., a logo) within a banner advertisement displayed on a second-party website (e.g., a news site) (’101 Patent, Abstract). This interaction triggers one of two paths. If a cookie on the user's computer indicates they are a new user, an interface option (e.g., a text field) appears within the ad to collect contact information. If the user is already known, the system uses the cookie to retrieve stored preferences and deliver customized information, all "without interrupting the browsing session" (’101 Patent, col. 4:37-54; Claim 1).
  • Technical Importance: This approach aimed to increase advertising conversion rates by transforming passive banner ads into a permission-based lead generation tool, capturing user interest at the moment of engagement without forcing the user to leave the page they are viewing (’101 Patent, col. 4:40-44).

Key Claims at a Glance

  • The complaint asserts independent claim 1 of the ’101 Patent (’101 Patent, Compl. ¶17).
  • Independent Claim 1 of the ’101 Patent recites a method with the following key elements:
    • Providing an advertisement from a first party for display on a computing device within a network communication associated with a second party.
    • The advertisement contains an "interactive element."
    • Receiving an indication that the recipient activated the interactive element.
    • Determining if an "identifier" (e.g., a cookie) is present on the computing device.
    • If no identifier is present: causing a text field to be displayed, receiving contact information, generating a user profile, and storing an identifier on the device.
    • If an identifier is present: retrieving a user profile from a database, retrieving additional information based on the profile, and delivering that information to the recipient "without interrupting the browsing session."
    • Recording the activation of the interactive element as tracking data in an analytics server.
  • The complaint reserves the right to assert additional claims (’101 Patent, Compl. ¶17).

III. The Accused Instrumentality

Product Identification

  • The accused instrumentality is "Amazon's Amazon Ads" platform (’101 Patent, Compl. ¶15). No specific product versions are identified.

Functionality and Market Context

  • The complaint alleges that Amazon Ads is a service through which Defendant "directly and/or indirectly develops, designs, manufactures, distributes, markets, offers to sell and/or sells infringing products and services" (’101 Patent, Compl. ¶3). The complaint does not provide specific details on the technical operation of the Amazon Ads platform beyond identifying it as the accused instrumentality. It is presented as a significant commercial advertising platform available to businesses and individuals throughout the United States (’101 Patent, Compl. ¶20).

IV. Analysis of Infringement Allegations

The complaint alleges that Defendant directly infringes at least claim 1 of the ’101 Patent by making, using, testing, and selling the Accused Products (Compl. ¶17). The complaint states that "claim charts attached hereto as Exhibit B describes how the elements of an exemplary claim 1 from the ’101 Patent are infringed by the Accused Products" (Compl. ¶22). However, Exhibit B was not attached to the provided complaint document. Therefore, a detailed, element-by-element analysis based on the complaint's specific allegations is not possible. The infringement theory relies entirely on the contents of the un-provided exhibit.

No probative visual evidence provided in complaint.

  • Identified Points of Contention:
    • Technical Questions: A primary factual question for the court will be whether the Amazon Ads platform actually performs the dual-path logic recited in Claim 1. Specifically, what evidence will show that interacting with an Amazon Ad can cause a text field to display within the advertisement itself for new users, or that it retrieves and uses pre-existing user profiles for known users to deliver information, all as claimed.
    • Scope Questions: The case may present a dispute over whether the common practice of redirecting a user to an advertiser's website upon clicking an ad "interrupt[s] the browsing session" as the term is used in the patent. The patent specification appears to distinguish the invention from such behavior, which raises a question of how the claim language should be construed in light of modern web advertising practices.

V. Key Claim Terms for Construction

  • The Term: "without interrupting the browsing session of the recipient"

    • Context and Importance: This negative limitation appears to be a central feature of the invention, distinguishing it from typical banner ads that redirect the user to a new webpage. The viability of the infringement claim may depend on whether the accused Amazon Ads functionality can be said to operate without such an "interruption." Practitioners may focus on this term because if a standard ad click-through to a new page is deemed an "interruption," it could present a significant hurdle for the infringement allegation.
    • Intrinsic Evidence for Interpretation:
      • Evidence for a Broader Interpretation: A party could argue that as long as the original webpage remains open in a browser tab, the overall "session" is not terminated and therefore not "interrupted," even if the user's active view is on a new page.
      • Evidence for a Narrower Interpretation: The specification provides strong support for a narrower meaning, stating that the invention allows for delivery of information "without the recipient leaving the website hosting the banner advertisements" (’101 Patent, col. 4:41-43) and that the "recipient remains able to interact with the entire webpage displaying the banner advertisement" (’101 Patent, col. 4:65-col. 5:1). This suggests an "interruption" occurs upon any navigation away from the host page.

  • The Term: "interactive element displayed within the advertisement"

    • Context and Importance: The definition of this term will determine what types of ad components meet this limitation. The infringement analysis will turn on whether any feature of an Amazon Ad qualifies as the claimed "interactive element" that triggers the subsequent steps of the claim.
    • Intrinsic Evidence for Interpretation:
      • Evidence for a Broader Interpretation: The claim language itself is general and not limited to a specific type of element, which could support a construction that covers any clickable portion of an advertisement.
      • Evidence for a Narrower Interpretation: The specification describes specific embodiments, such as an area "denoted by a logo 156 and 164" (e.g., "eHitme" in Fig. 2), that, when activated, "causes an interface option, such as a text field 158, to appear" (’101 Patent, col. 4:7-10). A defendant may argue that the term should be limited to elements that trigger such an in-advertisement interface, rather than a simple hyperlink.

VI. Other Allegations

  • Willful Infringement: While the complaint does not use the word "willful," it lays a foundation for such a claim by alleging that "Defendant has made no attempt to design around the claims of the ’101 Patent" (Compl. ¶18) and that "Defendant did not have a reasonable basis for believing that the claims of the ’101 Patent were invalid" (Compl. ¶19). The prayer for relief requests enhanced damages under 35 U.S.C. § 284 and a finding of an exceptional case under § 285, remedies often associated with findings of willful infringement (Compl. ¶B, C). The allegations appear to be based on post-suit conduct, as no facts supporting pre-suit knowledge are alleged.

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

  1. A central issue will be one of claim construction and scope: can the phrase "without interrupting the browsing session" be interpreted to read on an advertising system that redirects a user to a different webpage? The resolution of this question, based on the patent's intrinsic evidence, may be dispositive of the infringement analysis.

  2. A key evidentiary and factual question will be whether the Amazon Ads platform performs the specific two-path method of Claim 1. The case will require evidence demonstrating that the accused system (a) displays a data-entry field within the ad unit for new users and (b) uses a cookie to retrieve a user profile and deliver information for known users, as opposed to simply using cookies for generalized ad targeting. The complaint's lack of specific factual allegations on this point leaves this as a primary open question.
