Case Timeline

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

U.S. Patent No. 6,983,270 - "Method and Apparatus for Displaying Database Search Results"

• Patent Identification: U.S. Patent No. 6,983,270, "Method and Apparatus for Displaying Database Search Results," issued January 3, 2006.

The Invention Explained

• Problem Addressed: The patent's background section describes the problem of conventional database search interfaces frequently returning "null responses" (e.g., "no documents found") when a user's query does not match any records, forcing the user to guess at valid search criteria (’270 Patent, col. 2:6-14; col. 3:1-3).
• The Patented Solution: The invention addresses this by implementing a method where, after a user makes an initial selection (e.g., chooses a data field or value), the system automatically updates the interface to display only the remaining search terms and logical operators (e.g., "AND," "OR") that are guaranteed to produce a non-null result (’270 Patent, Abstract; col. 3:6-10). This process, illustrated in the flowchart of Figure 6, interactively guides the user toward a successful search by proactively eliminating impossible query combinations (’270 Patent, Fig. 6).
• Technical Importance: This approach sought to improve the usability of database search tools, especially for non-expert users, by preventing search failures before they occur rather than requiring users to reformulate queries after a null result (’270 Patent, col. 2:36-46).

Key Claims at a Glance

• The complaint asserts independent claim 1 of the ’270 Patent (Compl. ¶23).
• The essential elements of independent claim 1 include:
  • displaying a set of entries and a set of operators from a database;
  • selecting an initial entry;
  • displaying valid results based on the selection;
  • updating the displayed set of operators based on the selection to only include operators that will produce at least one valid result;
  • selecting an operator from the updated set;
  • updating the displayed set of entries in response to the selected operator to only include entries that will produce at least one valid result;
  • selecting an entry from the updated set;
  • updating the displayed set of valid results; and
  • repeating the updating and selecting steps until a desired result is achieved.

III. The Accused Instrumentality

Product Identification

• The complaint identifies Defendant's "Netforum Pro" software platform as the "Accused Instrumentality" (Compl. ¶17).

Functionality and Market Context

• The complaint alleges that Netforum Pro is a web-based customer relationship management (CRM) application that provides a method for searching a database (Compl. ¶17; p. 6). The system allegedly allows users to construct queries by selecting from various filters and operators to find records (Compl. ¶23(ii)-(iii)). A screenshot from the accused product's documentation displays an "Advanced Search" interface with rows of data fields, each paired with a dropdown menu of logical operators (Compl. p. 8). Another screenshot shows a list of search results, described as "a set of valid results," returned after executing a query (Compl. p. 9).
• The complaint alleges that Defendant generates substantial financial revenues from the Accused Instrumentalities (Compl. ¶22).

IV. Analysis of Infringement Allegations

U.S. Patent No. 6,983,270 Infringement Allegations

• Identified Points of Contention:
  • Scope Questions: A central question may be whether the functionality of the accused Netforum Pro product meets the "updating" limitations of the claim. The claim requires that the sets of available operators and entries are dynamically restricted based on prior user selections to guarantee a valid result. The complaint alleges this occurs, but the provided evidence does not explicitly show the list of available options changing in response to a user's selection.
  • Technical Questions: The infringement analysis may focus on the specific mechanism by which the accused product is alleged to "update" the available choices. The key technical question is whether Netforum Pro is architected to proactively prevent null-result queries, as the patent teaches (’270 Patent, col. 2:25-29), or whether it allows a user to construct a syntactically correct query that may nonetheless fail to return any records.

V. Key Claim Terms for Construction

• The Term: "updating"

• Context and Importance: This term appears in multiple steps of claim 1 and describes the core, active function of the invention. The infringement case may hinge on whether the accused product’s functionality can be characterized as "updating" in the sense required by the patent, which is dynamically filtering available choices to prevent null results.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The term's plain and ordinary meaning might suggest any modification or change to the display in response to user input. The specification mentions that an "updating" step may simply display "interim results" (’270 Patent, col. 10:4-6), which could be argued to support a broader definition.
  • Evidence for a Narrower Interpretation: The specification repeatedly links "updating" to the specific technical purpose of avoiding null values by eliminating choices that are "irrelevant or logically impossible" (’270 Patent, col. 3:5-8). The patent states that an important element is "preventing the user from being able to create a search command producing unwanted results" (’270 Patent, col. 10:17-20), suggesting "updating" is not just any change, but a specific, preventative filtering action.

• The Term: "valid result"

• Context and Importance: The purpose of the claimed "updating" steps is to ensure the query produces a "valid result." The construction of this term will define the required outcome of the accused process.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: A party could argue that a "valid result" is any logically sound outcome of a database query, which could include an empty set if no records match the criteria.
  • Evidence for a Narrower Interpretation: The patent's background and summary are centrally focused on the problem of "null responses" (’270 Patent, col. 2:25-26; col. 3:1). The claim language requiring that combined entries and operators "produce at least one valid result" (’270 Patent, col. 11:63, col. 12:2) strongly suggests that a "valid result" must be a non-empty set containing at least one record.

VI. Other Allegations

• Indirect Infringement: The complaint alleges inducement by advertising and providing the accused Netforum Pro services for use by others in an infringing manner (Compl. ¶¶ 28, 31). Plaintiff alleges Defendant knew or should have known its actions would cause infringement (Compl. ¶29).
• Willful Infringement: The willfulness allegation is based on knowledge obtained from the filing and service of the complaint itself (Compl. ¶27). The complaint also asserts a theory of willful blindness, alleging Defendant has a practice of not reviewing the patent rights of others before launching its products (Compl. ¶32).

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

• A key evidentiary question will be one of technical operation: does the accused Netforum Pro system perform the dynamic "updating" recited in claim 1? The case may turn on evidence demonstrating whether the system actively alters the lists of available search operators and subsequent data entries in real-time based on a user's prior selections to guarantee a non-null result, as the patent specification describes.
• A central legal issue will be one of definitional scope: can the term "valid result" be construed to mean any logically correct query output, or does the patent's intrinsic evidence limit its meaning to a non-empty result set containing at least one record?
