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

U.S. Patent No. [10,389,396](https://ai-lab.exparte.com/patent/10389396) - "TERRAIN AWARENESS AND WARNING AIRCRAFT INDICATOR EQUIPMENT"

• Patent Identification: U.S. Patent No. 10,389,396, "TERRAIN AWARENESS AND WARNING AIRCRAFT INDICATOR EQUIPMENT", issued August 20, 2019.

The Invention Explained

• Problem Addressed: The patent describes the need for pilots, particularly when flying an instrument approach, to maintain awareness of surrounding terrain like mountains and buildings to ensure safe navigation (’396 Patent, Abstract; col. 4:45-50). Traditional navigation methods may not seamlessly integrate this awareness with flight path data.
• The Patented Solution: The invention is a system and method that uses a "terrain awareness and warning system" (which includes a GPS receiver and a geographical database) to determine an aircraft's position relative to a "location of interest" (e.g., an airport) (’396 Patent, col. 23:51-52; col. 24:3-6). It then generates and provides two sets of data to an electronic display: first, an "aircraft situation display image" showing the location of interest relative to the aircraft, and second, the calculated distance and bearing values to that location (’396 Patent, col. 23:56-65).
• Technical Importance: This approach consolidates critical navigational data—a visual map, distance, and bearing—onto a single display, which can reduce pilot workload and enhance situational awareness during critical phases of flight (’396 Patent, col. 4:45-54).

Key Claims at a Glance

• The complaint asserts independent claims 1 (a method) and 13 (a system) (Compl. ¶¶14-15).
• Independent Claim 1 (Method):
  • determining a location of interest relative to an aircraft using a terrain awareness and warning system;
  • calculating a distance value and a bearing value for the location of interest relative to the aircraft;
  • providing first display data to an electronic display, configured to cause the display to show an aircraft situation display image indicating the location of interest; and
  • providing second display data to the electronic display, configured to cause the display to show the calculated distance and bearing values.
• Independent Claim 13 (System):
  • an electronic display; and
  • an electronic processor configured to perform the functional steps recited in method claim 1.
• The complaint does not explicitly reserve the right to assert dependent claims, but the prayer for relief is broad (Compl. ¶a, p. 7).

III. The Accused Instrumentality

Product Identification

• The complaint identifies the "AviGuide HUD" as the Accused Product (Compl. ¶17).

Functionality and Market Context

• The AviGuide HUD is alleged to be a "self-contained, fault-tolerant, multi-function display" (Compl. ¶17). The complaint alleges it provides displays and processors that assist pilots in navigation by determining the aircraft's real-time situation using terrain maps (Compl. ¶18). The complaint does not provide further detail on the product's market position or commercial significance.

IV. Analysis of Infringement Allegations

The complaint references a claim chart in an "Exhibit B" that was not filed with the public complaint; this analysis is based on the narrative allegations in the complaint body (Compl. ¶17).

'396 Patent Infringement Allegations

No probative visual evidence provided in complaint.

Identified Points of Contention

• Scope Questions: The complaint's allegations for infringement of the method claim are qualified with the phrase "at least in internal testing and usage" (Compl. ¶¶18-21). This raises the question of whether the Accused Product, as sold and used by customers, necessarily performs all steps of the claimed method, which may be relevant to allegations of direct infringement by end-users.
• Technical Questions: A key question will be whether the "terrain maps" allegedly used by the Accused Product (Compl. ¶18) meet the definition of a "terrain awareness and warning system" as required by the claims. The complaint does not specify the source or capabilities of these maps beyond their use for navigation.

V. Key Claim Terms for Construction

• The Term: "terrain awareness and warning system"
• Context and Importance: This term appears in both asserted independent claims and defines the core system used to generate the navigational data. Its construction will be central to determining infringement, as the Plaintiff must prove the AviGuide HUD includes or constitutes such a system.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The patent specification suggests this can be a combination of existing components, stating that a "GPS receiver and geographical database are included in a terrain awareness and warning system" (’396 Patent, col. 24:14-17). This may support a construction that does not require a standalone, dedicated piece of hardware pre-labeled as a "terrain awareness and warning system."
  • Evidence for a Narrower Interpretation: The term itself is a recognized term of art in the aviation industry (TAWS). A defendant may argue that the term should be limited to systems that meet specific regulatory or industry standards for TAWS, which typically include predictive forward-looking alerts, beyond just displaying terrain from a database. The patent's title also uses the full phrase, potentially supporting an argument that it carries its specialized industry meaning.

VI. Other Allegations

• Indirect Infringement: The complaint makes a conclusory allegation of induced infringement, stating Defendant encouraged infringement (Compl. ¶28). It does not, however, plead specific facts to support this, such as references to user manuals, advertisements, or other instructions that would teach or encourage users to operate the AviGuide HUD in an infringing manner.
• Willful Infringement: The complaint alleges Defendant had knowledge of the '396 Patent "at least as of the service of the present Complaint" (Compl. ¶26). This allegation, on its face, supports a claim for post-filing willfulness only and does not assert pre-suit knowledge of the patent or infringement.

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

1. A central issue will be one of claim scope: will the term "terrain awareness and warning system" be construed broadly to cover any system using a GPS and terrain database for navigation, as suggested by the patent's definition, or will it be narrowed to its more specific meaning as a term of art in the aviation industry, which may require more advanced warning functionalities?
2. A key evidentiary question will be whether the Plaintiff can demonstrate that the accused AviGuide HUD, as commercially sold, performs every element of the asserted claims. The complaint's reliance on allegations of "internal testing and usage" and the absence of a public claim chart suggest that proving direct infringement by customers may be a focal point of discovery.
3. The sufficiency of the indirect infringement allegations presents a potential procedural question. The complaint's lack of specific factual support for inducement may make this claim vulnerable to early dismissal motions.
