511 Tech v. Oracle Corp
Key Events
Complaint
I. Executive Summary and Procedural Information
- Parties & Counsel:
- Plaintiff: 511 Technologies Inc.; Caddo Systems, Inc. (Texas)
- Defendant: Oracle Corp. (Delaware)
- Plaintiff’s Counsel: Russ August & Kabat
- Case Identification: 2:17-cv-00179, E.D. Tex., 03/06/2017
- Venue Allegations: Plaintiff alleges venue is proper because Defendant has done business in the district, maintains places of business within Texas, and has committed acts of patent infringement in the district.
- Core Dispute: Plaintiff alleges that Defendant’s HRMS 9.1 software infringes two patents related to graphical user interface methods for navigating hierarchical information systems.
- Technical Context: The technology addresses inefficiencies in navigating traditional hierarchical menus by creating a persistent and interactive "active path" (i.e., a breadcrumb trail) that allows users to browse and access different levels of the hierarchy without starting over from the root.
- Key Procedural History: The complaint notes that during the prosecution of U.S. Patent No. 8,352,880, the inventor distinguished the claims from the MacPhail prior art reference based on the feature of displaying items upon "provisional selection" of an active link "without affecting the active path," a distinction that may be central to claim scope. The patents-in-suit are part of a five-patent family and are subject to terminal disclaimers.

II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 8,352,880 - ACTIVE PATH NAVIGATION SYSTEM, Issued January 8, 2013
The Invention Explained
- Problem Addressed: The patent describes conventional "collapsing menu" systems as inefficient because navigation must always restart from the root level, preventing experienced users from directly accessing known, deeper levels of the hierarchy (Compl. ¶12; ’880 Patent, col. 1:29-36, col. 2:1-3). Alternative path-based systems, like command-line navigation, require users to memorize complex hierarchical sequences, which is time-consuming and cumbersome (’880 Patent, col. 2:22-29).
- The Patented Solution: The invention proposes a graphical user interface feature called an "Active Path," which is an interactive sequence of links (i.e., a breadcrumb trail) that is dynamically built as a user navigates deeper into a hierarchical structure. This path allows a user to "provisionally select" (e.g., roll over) a link to see items at that level without altering the path itself, and to select a link to jump directly to a higher level in the hierarchy ('880 Patent, Abstract; col. 4:31-44).
- Technical Importance: This approach seeks to improve user interface efficiency by maintaining the user's "sense of orientation" while providing rapid access to any level within the current navigational context (Compl. ¶3; ’880 Patent, col. 4:40-44).
Key Claims at a Glance
- The complaint asserts "one or more claims" of the '880 Patent (Compl. ¶35). Independent claim 1 is representative:
- providing a graphical menu interface displaying the items of a given level of the information structure and enabling selection thereof;
- dynamically constructing an active path as a sequence of active links after an item of the information structure has been selected;
- upon provisional selection of any said active link, displaying one or more items on a given level of the information structure without affecting the active path; and
- said active links allowing a user to access an item in the information structure by selecting from the one or more items displayed by one of the active links on the active path.
- The complaint’s allegation of infringement of "one or more claims" implicitly reserves the right to assert dependent claims.
U.S. Patent No. 7,216,301 - ACTIVE PATH NAVIGATION SYSTEM, Issued May 8, 2007
The Invention Explained
- Problem Addressed: As a parent to the ’880 Patent, this patent addresses the same technical problem: the inefficiency of conventional collapsing menu systems that require navigation to always commence from the root level (’301 Patent, col. 1:29-36, col. 2:1-3).
- The Patented Solution: The invention is a method for creating a dynamic "Active Path" as a user selects items in a menu. This path consists of a sequence of "active links," each corresponding to a level in the hierarchy. The key innovation is that each active link allows a user to "directly browse" all items on that level, including subordinate items, without the main Active Path being altered or reset (’301 Patent, Abstract; col. 2:46-53, col. 4:51-58).
- Technical Importance: The invention provides a method to accelerate navigation within complex information structures by making the user's navigation history persistent and interactive (’301 Patent, col. 2:1-3).
Key Claims at a Glance
- The complaint asserts "one or more claims" of the ’301 Patent (Compl. ¶27). Independent claim 1 is representative:
- providing a graphical user menu system displaying the items of a given level... and enabling selection thereof;
- dynamically constructing an Active Path as a sequence of active links as items are selected...;
- said active links providing direct access to one of a function, corresponding level and menu item without the need to navigate using said graphical user menu system;
- each said active link enabling the user to directly browse all items on any given level of the hierarchical information structure including all hierarchically subordinate items without affecting the Active Path.
- The complaint’s allegation of infringement of "one or more claims" implicitly reserves the right to assert dependent claims.
III. The Accused Instrumentality
Product Identification
Defendant’s "HRMS 9.1 software" is identified as the "Accused Product" (Compl. ¶27).

Identified Points of Contention
- Technical Questions: The complaint's infringement allegations largely consist of conclusory restatements of the claim language without specific factual support describing how the HRMS 9.1 software operates (Compl. ¶¶27, 35). A central question will be whether discovery produces evidence that the accused software performs the specific functions required by the claims.
- Scope Questions: For the ’880 Patent, a key dispute may arise over whether the accused system performs "provisional selection... without affecting the active path." The complaint’s allegation of merely "allowing the display of one or more items" (Compl. ¶35) is less specific than the claim language, which was a basis for allowance during prosecution (Compl. ¶15). Similarly, for the ’301 Patent, there is a potential mismatch between the claim requirement to "browse all items on any given level... including all hierarchically subordinate items" and the complaint's more general allegation of providing "direct access" (Compl. ¶27).
V. Key Claim Terms for Construction
The Term: "provisional selection" ('880 Patent, Claim 1)
- Context and Importance: This term is critical, as the complaint identifies the feature of displaying items upon "provisional selection... without affecting the active path" as the basis for overcoming the MacPhail prior art reference during prosecution (Compl. ¶15). The definition of this term will be central to determining infringement.
- Intrinsic Evidence for a Broader Interpretation: The specification equates this term with a user "browsing" by "'rolling-over' (provisionally selecting) an element with a pointing device such as a mouse" ('880 Patent, col. 4:36-40). Plaintiff may argue this supports a broad construction covering common "mouse-over" or "hover" functionalities.
- Intrinsic Evidence for a Narrower Interpretation: The specification also draws a clear distinction between "browsing" (rolling over) and "selecting" (clicking) ('880 Patent, col. 4:45-50). Defendant may argue that "provisional selection" requires a specific user action that results in the display of sibling items without hiding other parts of the hierarchy, a functional outcome that may not be present in a generic hover-activated menu.
The Term: "browse all items on any given level... including all hierarchically subordinate items without affecting the Active Path" ('301 Patent, Claim 1)
- Context and Importance: The scope of this "browsing" limitation is a potential point of dispute, as the complaint's allegations for the '301 patent focus on "direct access" and do not explicitly map to this element (Compl. ¶27). The functionality of browsing both sibling and subordinate items from an active link is a specific feature of the claimed invention.
- Intrinsic Evidence for a Broader Interpretation: The patent describes browsing as "'rolling over' a menu item or active link... to view the siblings," noting that the "Active Path 100 is not affected by the user's browsing" ('301 Patent, col. 4:51-58). This could support an interpretation where any non-destructive display of related items meets the limitation.
- Intrinsic Evidence for a Narrower Interpretation: The claim language is highly specific, requiring the ability to browse "all items on any given level" and "all hierarchically subordinate items." Defendant may argue this requires a comprehensive display of the entire sub-hierarchy associated with an active link, a more complex function than a simple drop-down menu showing only immediate children.
VI. Other Allegations
Willful Infringement
- The complaint reserves the right to seek a finding of willful infringement "to the extent that facts learned in discovery show" that Defendant's infringement was or has been willful (Compl. ¶¶32, 40). The complaint does not allege pre-suit knowledge or plead any specific facts that would currently support a claim for willfulness.
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of evidentiary sufficiency: Can the Plaintiff, beyond the conclusory allegations in the complaint, produce technical evidence demonstrating that Oracle's HRMS 9.1 software actually performs the specific, nuanced functions required by the asserted claims—particularly the "provisional selection" and comprehensive "browsing" features that were highlighted during prosecution and appear in the independent claims?
- A second central issue will be one of claim scope: How will the court construe the term "provisional selection" from the '880 patent and the phrase "browse all items... including all hierarchically subordinate items" from the '301 patent? The case may turn on whether these terms are given a broad meaning that could read on common user interface elements or a narrower one tied to the specific, multi-part functionalities described in the patent specifications and distinguished from the prior art.
