2:10-cv-00265
Geotag Inc v. Frontier Communications Corp
I. Executive Summary and Procedural Information
- Parties & Counsel:
- Plaintiff: GeoTag Inc. (Delaware)
- Defendant: Frontier Communications Corporation (Delaware), Local.com Corporation (Delaware), Dex One Corporation (Delaware), and others.
- Plaintiff’s Counsel: Friedman, Suder & Cooke, P.C.
- Case Identification: 2:10-cv-00265, E.D. Tex., 07/23/2010
- Venue Allegations: Plaintiff alleges venue is proper in the Eastern District of Texas because Defendants have allegedly committed acts of infringement and transact business within the district. The complaint also notes that the Court previously presided over a case involving the same patent-in-suit, which included a claim construction ruling.
- Core Dispute: Plaintiff alleges that Defendants’ online directory websites infringe a patent related to a system for organizing and accessing information based on a hierarchy of geographic locations and topics.
- Technical Context: The technology concerns early Internet-era methods for creating geographically-searchable online directories, akin to a digital "Yellow Pages," by structuring data hierarchically by location.
- Key Procedural History: The complaint states that the patent-in-suit was the subject of a prior lawsuit in the same court, Geomas (International), Ltd., et al. vs. Idearc Media Services-West, Inc., et al., which resulted in a claim construction (Markman) order on November 20, 2008. This prior ruling may significantly influence the interpretation of claim terms in the present case.

II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 5,930,474 - "Internet Organizer for Accessing Geographically and Topically Based Information"
- Patent Identification: U.S. Patent No. 5,930,474, "Internet Organizer for Accessing Geographically and Topically Based Information", issued July 27, 1999.
The Invention Explained
- Problem Addressed: The patent describes a shortcoming of early Internet search tools where information was not effectively organized by geography, making it difficult for users to find goods and services within a specific local area (’474 Patent, col. 2:21-34). Existing systems were primarily organized by subject matter or keywords, not physical location.
- The Patented Solution: The invention is a software interface and system that organizes online information into a predefined hierarchy of geographical areas (e.g., Continent -> Country -> State -> City). A user can navigate this geographic hierarchy and then perform a topical search within the selected location (’474 Patent, Abstract). The system integrates a "geography database" with a "local content database" and a "yellow pages database" to allow users to efficiently access location-specific information (’474 Patent, col. 4:54-65; Fig. 2A-2C).
- Technical Importance: The invention provided a structured method for searching the otherwise disorganized Internet in a manner analogous to traditional, paper-based local directories, thereby improving the utility of online search for local commerce (’474 Patent, col. 2:50-54).
Key Claims at a Glance
- The complaint alleges infringement of "one or more of the claims" without specifying which ones (Compl. ¶22). The primary independent claim is Claim 1.
- Independent Claim 1 of the ’474 Patent recites these essential elements:
- A system with a computer network and a plurality of computers with access to it.
- An "organizer" that receives search requests.
- The organizer comprises a "database of information organized into a hierarchy of geographical areas" which is "further organized into topics."
- A "search engine" that can search "geographically and topically."
- The search engine is configured to "select one of said hierarchy of geographical areas prior to selection of a topic."
- The system includes a feature where "at least one of said entries associated with a broader geographical area is dynamically replicated into at least one narrower geographical area."
- The search engine is configured to search topics "within said selected geographical search area."
III. The Accused Instrumentality
Product Identification
- The accused instrumentalities are the online directory websites operated by the various Defendants, including
frontierpages.com,local.com,dexknows.com,yelp.com, and others (Compl. ¶¶ 24-37).
Functionality and Market Context
- The complaint alleges that the accused websites are systems "for providing geographical and topical information to Internet users" (Compl. ¶23). These websites function as online business directories or "yellow pages," allowing users to find listings for goods and services. The core accused functionality appears to be the ability for a user to specify a geographic location (such as a city and state) and a business category (a topic) to retrieve relevant local listings (Compl. ¶23). No probative visual evidence provided in complaint.
IV. Analysis of Infringement Allegations
The complaint does not contain a claim chart or detailed infringement contentions. The analysis below is based on the general infringement theory implied by the allegations against the accused online directory services.
'474 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| a database of information organized into a hierarchy of geographical areas wherein entries ... is further organized into topics | The accused websites allegedly operate databases of business listings that are categorized by geographic location (e.g., state, city) and by business type or topic (e.g., "Restaurants," "Plumbers"). | ¶23 | col. 38:45-49 |
| a search engine ... configured to search geographically and topically | The search functionality of the accused websites allegedly allows users to conduct searches based on both a selected location and a selected topic. | ¶23 | col. 38:50-52 |
| said search engine further configured to select one of said hierarchy of geographical areas prior to selection of a topic | The user interfaces of the accused websites allegedly guide users to select a geographic area as part of the process of searching for topical information. | ¶23 | col. 38:52-55 |
| at least one of said entries associated with a broader geographical area is dynamically replicated into at least one narrower geographical area | The complaint does not provide sufficient detail for analysis of this element. | --- | col. 38:55-58 |
- Identified Points of Contention:
- Scope Questions: A potential issue is whether the architecture of the Defendants' modern web services matches the specific three-database structure (geography, local content, yellow pages) disclosed in the patent (’474 Patent, Fig. 2A-C). The court may need to determine if a more integrated, modern database architecture falls within the scope of the claims.
- Technical Questions: A key question is whether the accused websites perform the function of "dynamically replicat[ing]" an entry from a "broader geographical area" into a "narrower" one, as required by Claim 1. The complaint provides no factual allegations on this point, and it raises the evidentiary question of how Defendants' systems handle and display listings for national or regional entities within a local search result.
V. Key Claim Terms for Construction
The Term: "hierarchy of geographical areas"
- Context and Importance: This term is foundational to the patent. Its construction is critical to determining whether the search functions on the accused websites, which may simply use city/state text fields, meet the claimed "hierarchy." The definition will determine if a structured, multi-level browsing system is required or if a simpler location-based filter suffices. The existence of a prior Markman ruling on this term will be a central factor (Compl. ¶19).
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The patent abstract refers generally to organizing information "predicated upon the geographical area," and the background section discusses associating information with "geographic areas" more broadly, which might support a less rigid structure (’474 Patent, Abstract; col. 2:63-65).
- Evidence for a Narrower Interpretation: The detailed description and figures illustrate a specific, nested structure: "the world, to a specific continent, to a specific country, to a specific state, etc." (’474 Patent, col. 8:35-39). Figure 2A shows a formal hierarchy from "World" down to "Point of Interest," which may support a narrower construction requiring multiple, distinct levels of navigation.
The Term: "dynamically replicated"
- Context and Importance: Practitioners may focus on this term because it appears to describe a specific technical action that distinguishes the invention from a simple database lookup. Infringement analysis will depend heavily on whether the accused systems perform an action that meets the definition of this term. The complaint's silence on this element suggests it will be a significant point of dispute.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The patent does not provide an explicit definition for "dynamically replicated," which could allow for an argument that any system that presents information from a central database in the context of a local search result meets the limitation.
- Evidence for a Narrower Interpretation: The term itself suggests an active process of copying or instantiating data for a specific purpose, rather than merely linking to it. A Certificate of Correction was issued for the patent to clarify the language of this limitation, underscoring its importance and suggesting it has a specific technical meaning that may be narrower than a general display of information (’474 Patent, Certificate of Correction).
VI. Other Allegations
- Indirect Infringement: The complaint includes boilerplate allegations of induced and contributory infringement but provides no specific facts to support the required elements of knowledge and intent, such as alleging that Defendants instructed their users to perform the infringing steps (Compl. ¶22; Prayer for Relief ¶a).
- Willful Infringement: The willfulness allegation is based on notice provided by the filing of the complaint itself, with no allegations of pre-suit knowledge (Prayer for Relief ¶c).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of claim scope versus evolving technology: can the specific, hierarchical database architecture described in the 1996-filed patent be construed to cover the complex, and potentially different, backend systems of the 2010-era accused websites?
- The case will likely involve a significant evidentiary and construction dispute over the "dynamically replicated" limitation. The litigation may turn on whether Plaintiff can prove, through discovery, that the accused systems perform a technical function that meets this specific claim requirement, a point on which the complaint is currently silent.
- A critical legal question will be the impact of prior claim construction: how will the court's 2008 Markman ruling from the Geomas litigation constrain the parties' arguments and shape the infringement analysis for claim terms that were previously construed?
