Case Timeline

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

U.S. Patent No. 8,397,177 - "Graphic-information flow method and system for visually analyzing patterns and relationships"

• Patent Identification: U.S. Patent No. 8,397,177, "Graphic-information flow method and system for visually analyzing patterns and relationships", issued March 12, 2013.

The Invention Explained

• Problem Addressed: The patent describes prior art computer graphic systems, like early GIS, as being "slow" and "unwieldy" for non-technical users. It notes that such systems do not provide for "seamless access to subset combinations from extensive data sets" and that their interfaces, which often require extensive scrolling or navigating to separate pages for details, break the "flow of the analytical thought process" (’177 Patent, col. 2:9-43).
• The Patented Solution: The invention is a display system that integrates data from various sources into an interactive, layered, and slotted "map" format. The system allows a user to manipulate "map components, layers, and annotations" to follow a "sustained, multi-faceted, analytical thought process" (’177 Patent, col. 6:10-25). Key aspects include using interactive keys to toggle layers of information and using pop-up windows to display annotations without navigating away from the main map view, thereby keeping the user oriented and focused (’177 Patent, col. 7:22-48; Fig. 6d).
• Technical Importance: The technology aimed to improve the user experience for complex data visualization by creating a more fluid and intuitive interface than the page-to-page, menu-driven systems prevalent at the time (’177 Patent, col. 2:1-7).

Key Claims at a Glance

• The complaint does not identify any specific claims, instead referring generally to "one or more claims" and referencing an external exhibit containing "Exemplary '177 Patent Claims" that was not provided with the complaint (Compl. ¶¶11, 16). For the purpose of this analysis, representative independent method claim 5 is examined.
• Independent Claim 5 (Method):
  • performing server-side operations to support interaction with a web browser client by generating and serving web page content;
  • presenting a first web page view including a first control panel area with a list of hotels and a map display area with an interactive map;
  • the map comprises a base map layer and at least one additional layer with hotel location symbols corresponding to the hotels in the list; and
  • the graphical user interface enables a user to show or hide subsets of the hotel location symbols in a particular layer.
• The complaint does not explicitly reserve the right to assert dependent claims but refers broadly to "one or more claims" of the ’177 Patent (Compl. ¶11).

III. The Accused Instrumentality

Product Identification

The complaint refers to the "Exemplary Defendant Products" identified in a non-proffered exhibit (Compl. ¶11). Based on the defendant’s identity, these are understood to be the Hotel Tonight website and mobile applications.

Functionality and Market Context

The accused products provide a service allowing end-users to search, filter, and book hotel accommodations. The complaint alleges that these products "practice the technology claimed by the '177 Patent" (Compl. ¶16). Functionally, this involves users interacting with a map-based interface to view hotel locations, apply filters (e.g., by price or amenity), and select specific hotels to view more detailed information. The complaint makes no specific allegations regarding the products' commercial importance. No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

The complaint alleges infringement but refers to claim charts in an external "Exhibit 2," which was not included with the filed document (Compl. ¶¶16, 17). The complaint’s narrative theory is that the "Exemplary Defendant Products practice the technology claimed by the ’177 Patent" and that they "satisfy all elements of the Exemplary ’177 Patent Claims" (Compl. ¶16). However, the complaint provides no specific factual allegations mapping any feature of the accused products to any specific limitation of any asserted claim. Because the complaint does not provide this information or the referenced exhibit, a claim chart summary and identification of specific points of contention cannot be produced.

V. Key Claim Terms for Construction

The following analysis is based on representative independent claim 5.

• The Term: "a first control panel area presenting a list of hotels"

• Context and Importance: This term appears to require a specific structural layout where a "control panel area" is distinct from the "map display area." Practitioners may focus on this term because modern web interfaces, like that potentially used by Hotel Tonight, often integrate search results directly onto or alongside a map in a fluid layout, which may not correspond to the more formally segregated panel structure shown in the patent’s figures (e.g., Fig. 6d, Fig. 10a). The case may turn on whether the accused product's interface meets this structural requirement.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The patent states the invention can be used with various hardware and that the GUI is a "template" (Compl. ¶9; ’177 Patent, col. 9:46-54). This could support an argument that the term is not limited to the exact layouts shown in the figures.
  • Evidence for a Narrower Interpretation: The patent consistently depicts control panels as distinct screen regions separate from the main map area, with their own defined functions, such as holding an index, keys, or tutorials (’177 Patent, Fig. 10a, elements c, d, e, f). This may support a narrower construction requiring a physically separate and identifiable panel.

• The Term: "hotel location symbol"

• Context and Importance: The infringement theory depends on the accused product displaying these symbols. The patent describes a highly structured system where symbols are tied to specific data, attributes, and layers (’177 Patent, col. 15:1-10). The question will be whether a simple price tag or pin icon on a map in the accused product constitutes a "symbol" within the meaning of the patent, or if the term requires a more complex object with the specific interactive and data-linked properties described in the specification.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: Claim 5 itself only requires that the symbol "correspond[] to a hotel in the list of hotels," suggesting any visual marker could suffice (’177 Patent, col. 30:10-12).
  • Evidence for a Narrower Interpretation: The detailed description explains that "smart graphics" are used as symbols that are "programmed to respond to user commands" and call a database to cause an action (’177 Patent, col. 9:33-38). This could support a narrower definition requiring more than a simple visual marker.

VI. Other Allegations

• Indirect Infringement: The complaint alleges induced infringement. It asserts that Defendant provides "product literature and website materials" which instruct end-users to use the accused products in an infringing manner (Compl. ¶14). It also alleges inducement based on sales made after Defendant gained knowledge of the patent via the complaint (Compl. ¶15).
• Willful Infringement: The complaint does not use the term "willful," but it alleges that service of the complaint "constitutes actual knowledge of infringement" and that Defendant's infringement has continued despite this knowledge (Compl. ¶¶13-14). This forms a basis for potential post-filing willful infringement and enhanced damages. The prayer for relief requests that the case be declared "exceptional" under 35 U.S.C. § 285 (Compl., Prayer for Relief E.i.).

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

1. A central procedural question will be one of pleading sufficiency: Given that the complaint fails to identify specific asserted claims and makes only conclusory allegations of infringement by referencing (but not providing) external claim charts, does it state a plausible claim for relief under the Twombly/Iqbal standard, or is it subject to dismissal?

2. A core substantive question will be one of structural scope: Can the patent’s claims, which describe a system with seemingly distinct components like a "control panel area" and a "map display area," be construed to read on a modern, integrated user interface where such components may be blended or absent?

3. A key evidentiary question will be one of functional operation: Does the accused hotel booking service, with its filtering and display features, actually perform the specific method of enabling a user to "show or hide subsets of the hotel location symbols in a particular layer," as required by the claims, or is there a fundamental mismatch in the technical operation and granularity of the patented method versus the accused service?
