Case Timeline

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

U.S. Patent No. 6,154,738 - "Methods and Apparatus for Disseminating Product Information via the Internet Using Universal Product Codes," issued November 28, 2000

The Invention Explained

• Problem Addressed: The patent's background section identifies the difficulty for consumers and resellers in locating detailed, up-to-date product information online, particularly when the uniform resource locator (URL) of the manufacturer's website is not known (’738 Patent, col. 1:40-52).
• The Patented Solution: The invention proposes a system where a standardized "universal product code" (such as a UPC) is embedded in a hyperlink on a web page. When a user activates the link, a request containing the product code is sent to a "cross-referencing resource." This resource looks up the code, identifies the correct Internet address for the server holding the product's information (e.g., the manufacturer's server), and sends a redirection message back to the user's browser, which then automatically fetches and displays the information from that address (’738 Patent, Abstract; col. 2:13-25). Figure 2 illustrates this architecture, showing a "Cross-Reference Table" (215) that maps product codes to Internet addresses.
• Technical Importance: The technology aimed to streamline e-commerce by allowing retailers to link to authoritative manufacturer data without having to host and maintain that information themselves, using product codes as a standardized access key (’738 Patent, col. 2:26-34).

Key Claims at a Glance

• The complaint asserts at least independent Claim 1 (Compl. ¶13).
• The essential elements of independent Claim 1 include:
  • Establishing a cross-referencing resource with a database of cross-references between product code values and Internet addresses.
  • Transmitting a web page containing a hyperlink that includes a specific universal product code value.
  • A user's web browser receiving the web page and, upon activation of the hyperlink, transmitting a first request message (containing the product code) to the cross-referencing resource.
  • The cross-referencing resource processing the first request to identify the corresponding Internet address and returning a redirection message to the browser.
  • The browser automatically responding by transmitting a second request message to that identified Internet address.
  • A web server at that address responding with product information, which the browser then automatically displays to the user.
• The complaint states that Plaintiff may assert other claims from the ’738 Patent (Compl. ¶13).

III. The Accused Instrumentality

Product Identification

• The accused instrumentalities are the "Polyvore shopping portal, www.polyvore.com, and any similar products and services" offered by the Defendant (collectively, "Products") (Compl. ¶14).

Functionality and Market Context

• The complaint describes the accused Products as an online ordering and e-commerce platform that disseminates product information online (Compl. ¶15). The system allegedly uses a database to create a correspondence between a product code (e.g., "130016-006-01") and an Internet address for a destination site that provides information about the product associated with that code (e.g., a "LANCASTER PARIS Pur Smooth Leather Bucket Bag") (Compl. ¶16). A screenshot provided in the complaint shows a product search results page from the Polyvore website (Compl. p. 5).

IV. Analysis of Infringement Allegations

’738 Patent Infringement Allegations

Identified Points of Contention

• Scope Questions: The patent defines "universal product codes" to include standard codes like UPCs as well as "any other multi-industry or single industry standard product designation system" (’738 Patent, col. 4:55-57). The complaint alleges that Polyvore's proprietary identifier (e.g., "130016-006-01") meets this definition (Compl. ¶16). This raises the question of whether a platform-specific, internal product code can be construed as a "single industry standard product designation system" as contemplated by the patent.
• Technical Questions: The complaint's visual evidence shows a hyperlink that appears to redirect through an affiliate marketing network (click.linksynergy.com) before reaching the final product page (forzieri.com) (Compl. p. 5). The infringement analysis may turn on whether this multi-hop architecture, involving an intermediary affiliate server, aligns with the two-request sequence ("first request" to a "cross-referencing resource" followed by a "second request" to a "particular Internet address") recited in Claim 1.

V. Key Claim Terms for Construction

• The Term: "universal product code"

• Context and Importance: The viability of the infringement claim hinges on whether the product identifiers used by Polyvore fall within the scope of this term. Practitioners may focus on this term because the accused system allegedly uses a proprietary code, not a publicly recognized standard like a UPC.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The patent provides an explicit definition that includes not only UPCs and EANs but also "any other multi-industry or single industry standard product designation system" (’738 Patent, col. 4:55-57). Plaintiff may argue this language is intentionally broad to capture any coding system used consistently within a given commercial context or industry, such as an e-commerce platform.
  • Evidence for a Narrower Interpretation: The specification’s examples and context focus on codes managed by external, inter-company standards bodies like the Uniform Code Council and EAN International (’738 Patent, col. 4:49-55). Defendant may argue that the term requires a code that is "universal" or "standard" across multiple entities, not one that is proprietary to a single platform.

• The Term: "cross-referencing resource"

• Context and Importance: The accused system appears to involve multiple components, including the Polyvore platform, an affiliate network server, and a third-party retailer's server (Compl. ¶16, ¶20, p. 5). Defining which of these components, alone or in combination, constitutes the "cross-referencing resource" is critical to mapping the accused system to the claim steps.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The Abstract states the resource "may take the form of an independent HTTP server, an LDAP directory server, or the existing Internet Domain Name Service (DNS)," suggesting flexibility in its implementation and that it is defined by its function of translating a code to an address (’738 Patent, Abstract).
  • Evidence for a Narrower Interpretation: Figures in the patent, such as Figure 2, depict a relatively centralized architecture with a distinct "Cross-Reference Table" (215) and "Query Handler" (204). Defendant may argue that the claim requires a more discrete component that performs the lookup, rather than a distributed process that spans multiple, unaffiliated third-party systems like an affiliate network.

VI. Other Allegations

The complaint does not contain counts for indirect or willful infringement.

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

• A core issue will be one of definitional scope: can the term "universal product code," which the patent defines with reference to industry-wide standards like UPCs, be construed to cover a proprietary, platform-specific identifier used within the accused e-commerce system?
• A key evidentiary question will be one of architectural mapping: does the accused system's multi-step redirection process, which appears to route through an intermediary affiliate marketing server, perform the same sequence of steps as the more direct, two-request method recited in Claim 1, or is there a fundamental mismatch in technical operation?
