Case Timeline

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

U.S. Patent No. 10,593,205 - "GPS and Warning System," issued March 17, 2020

The Invention Explained

• Problem Addressed: The patent describes the significant risk faced by drivers of high-profile vehicles (e.g., commercial trucks, buses, RVs) of colliding with low-clearance structures such as bridges, tunnels, and underpasses, a problem exacerbated at highway speeds where stopping in time is difficult (U.S. Patent No. 10,593,205, col. 1:56-68).
• The Patented Solution: The invention is a vehicle-mounted GPS and warning system. A computer module within the device is programmed with a database of infrastructure locations and their clearance heights. By comparing the vehicle's GPS location to this database, the system can provide audible and visual warnings to the driver if they are approaching a structure with insufficient clearance, and can also suggest alternate routes to avoid the hazard (’205 Patent, col. 2:31-59). The system is intended to "safely alert, and reroute the driver, should the vehicle be approaching a structure with low clearance" (’205 Patent, col. 2:27-30).
• Technical Importance: The technology provides an automated, location-aware safety system to prevent collisions that are otherwise difficult for drivers to avoid in real-time due to reliance on static road signs and the challenge of knowing their vehicle's precise height including its load (’205 Patent, col. 1:60-65).

Key Claims at a Glance

• The complaint does not specify which claims are asserted, referring only to "exemplary claims" identified in an unattached exhibit (Compl. ¶¶11, 16). The patent contains two independent claims, Claim 1 and Claim 6.
• Independent Claim 1 recites a "GPS and warning system for an automobile" with the following essential elements:
  • a main body with a hollow interior volume;
  • a computer module within the body, "adapted to be programmed with information pertaining to existing roads, bridges, viaducts, and underpasses";
  • a GPS module within the body to provide location information;
  • at least one warning mechanism (e.g., audible sound) connected to the computer module; and
  • a display screen to provide visual information to the driver, including the height of an approaching structure and alternate routes.
• Independent Claim 6 recites a "combination of an automobile and a GPS and warning device," comprising:
  • an automobile with an engine and passenger compartment; and
  • a GPS and warning system (as recited in Claim 1) located within the passenger compartment.

III. The Accused Instrumentality

Product Identification

The complaint does not identify any specific accused products or services by name. It refers generally to "Exemplary Defendant Products" that are purportedly identified in "the charts incorporated into this Count" (Compl. ¶11). These charts, referenced as Exhibit 2, were not filed with the complaint.

Functionality and Market Context

The complaint does not provide sufficient detail for analysis of the functionality or market context of the accused products. It makes only the conclusory allegation that the "Exemplary Defendant Products practice the technology claimed by the '205 Patent" (Compl. ¶16).

IV. Analysis of Infringement Allegations

The complaint alleges that Defendant directly infringes the ’205 Patent by "making, using, offering to sell, selling and/or importing" the accused products (Compl. ¶11). The pleading relies entirely on claim charts in an unattached "Exhibit 2" to provide the factual basis for this allegation (Compl. ¶¶16-17). The narrative states that these charts compare the "Exemplary '205 Patent Claims to the Exemplary Defendant Products" and demonstrate that the products "satisfy all elements" of the asserted claims (Compl. ¶16). Without the exhibit, the specific factual theory of infringement for any claim element remains unspecified. No probative visual evidence provided in complaint.

Identified Points of Contention

• Evidentiary Question: A primary issue will be whether Plaintiff can produce evidence linking the general allegations to specific functionalities in Defendant's unidentified products. The complaint's current lack of factual detail on how any accused product meets any specific claim limitation raises the question of whether it meets federal pleading standards.
• Technical Question: A likely point of dispute, once products are identified, will be whether they contain a "computer module... programmed with information" as claimed (’205 Patent, col. 6:18-21). This may focus on whether the accused devices use a pre-loaded, static database of obstacle information, as described in the patent, or if they access such information dynamically from a remote server, which may raise questions of technical and legal equivalence.

V. Key Claim Terms for Construction

• The Term: "computer module... adapted to be programmed with information pertaining to existing roads, bridges, viaducts, and underpasses" (Claim 1)

• Context and Importance: This limitation is the technological core of the invention, defining how the system stores the critical data used for issuing warnings. The interpretation of "programmed with" will be central to determining the scope of infringement, as it distinguishes between different methods of data acquisition (e.g., pre-loaded vs. real-time).

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The claim language "adapted to be programmed" could be argued to encompass any system capable of receiving and using the specified information, regardless of whether it is pre-loaded at the factory or downloaded dynamically during operation.
  • Evidence for a Narrower Interpretation: The specification's description of the invention's purpose as warning drivers based on "including the actual measurements of each and every structure along with GPS coordinates" could suggest a system containing a comprehensive, pre-existing database, rather than one that relies on external, on-demand data sources (’205 Patent, col. 2:24-27).

• The Term: "automobile" (Claims 1, 6)

• Context and Importance: The patent's abstract and background repeatedly and exclusively refer to the problems faced by "truckers, bus and RV drivers" (’205 Patent, Abstract; col. 1:33-35). Practitioners may focus on this term because the defendant could argue that the patent's scope is implicitly limited to these large, commercial-type vehicles, potentially excluding passenger cars from the definition of "automobile" as used in the claims.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The term "automobile" itself is broad and is not explicitly defined or disclaimed in the patent. A party could argue it should be given its plain and ordinary meaning, which would include standard passenger cars.
  • Evidence for a Narrower Interpretation: A party could argue that the patent specification, by exclusively discussing the unique problems of high-profile commercial vehicles, provides a specific context that limits the term "automobile" to that class of vehicle for the purposes of the claims (’205 Patent, col. 1:56-58).

VI. Other Allegations

• Indirect Infringement: The complaint alleges induced infringement, stating that Defendant distributes "product literature and website materials" that instruct end users on how to use the accused products in an infringing manner (Compl. ¶14). The allegation specifies that this inducement has occurred "at least since being served by this Complaint" (Compl. ¶15).
• Willful Infringement: The complaint alleges that service of the complaint and its (unattached) claim charts provided Defendant with "actual knowledge" of its infringement (Compl. ¶13). It alleges that any continued infringement after this date is willful (Compl. ¶14). This frames the willfulness claim as being based on post-suit conduct.

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

1. Factual Sufficiency and Product Identification: The most immediate question is whether the complaint’s conclusory allegations, which rely entirely on an unattached exhibit, are sufficient to proceed. A central task for the plaintiff will be to identify the specific "Exemplary Defendant Products" and articulate a factual basis for how they meet each claim limitation.

2. Claim Scope and Data Architecture: A core technical issue will be one of definitional scope: does the claim limitation "computer module... programmed with information" require a device with a self-contained, pre-loaded database as arguably taught in the specification, or can it be construed to cover modern navigation systems that dynamically query and receive clearance data from a cloud-based service?

3. The "Automobile" Limitation: The case may turn on a key claim construction question: is the term "automobile" limited by the specification's consistent focus on high-profile commercial vehicles (trucks, buses, RVs), or does it retain its broader, ordinary meaning? The answer will determine the total universe of potentially infringing products.
