  • Plaintiff’s Counsel: Insight, PLC
• Case Identification: 2:26-cv-00856, C.D. Cal., 01/28/2026
• Venue Allegations: Plaintiff alleges venue is proper based on Defendant operating regular and established places of business within the district, including a specific Lowe's store in Los Angeles, where the Accused Products are allegedly sold or offered for sale.
• Core Dispute: Plaintiff alleges that Defendant’s sale of Husqvarna robotic lawnmowers featuring the Exact Positioning Operating System (EPOS) infringes a patent related to vehicle navigation systems that manage route deviations involving waypoints.
• Technical Context: The technology at issue involves autonomous navigation systems that use virtual, satellite-defined boundaries and waypoints, a key feature in modern robotic devices like lawnmowers that are moving away from physical perimeter wires.
• Key Procedural History: The complaint notes that the patent-in-suit was the subject of an inter partes review proceeding where the Patent Trial and Appeal Board denied institution on May 16, 2024, suggesting the patent's claims have previously withstood a validity challenge.

Case Timeline

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

U.S. Patent No. 8,649,971 - "Navigation Device"

• Patent Identification: U.S. Patent No. 8,649,971, "Navigation Device," issued February 11, 2014 (the "’971 Patent"). Compl. ¶1

The Invention Explained

• Problem Addressed: The patent’s background describes a problem with prior art navigation devices where, if a user deviates from a pre-planned route containing waypoints, the device would automatically re-calculate a new route without regard for the user's intent. This could force a user back to a waypoint they intended to skip, which was described as being "inferior in user-friendliness." ’971 Patent, col. 2:48-55
• The Patented Solution: The invention provides a user-centric feedback loop. When the system determines that the vehicle has deviated from its route and is now traveling on a path after a missed waypoint, it outputs a message to the user asking for a command on how to proceed—specifically, whether to still travel via the missed waypoint. ’971 Patent, Abstract; col. 2:15-26 This gives the user explicit control over the re-routing decision after a deviation, rather than the system making an automatic, and potentially incorrect, assumption.
• Technical Importance: The claimed solution introduces a specific conditional logic into automated navigation that prioritizes user intent over rigid, automatic re-routing when a planned waypoint is missed. Compl. ¶¶24, 26

Key Claims at a Glance

• The complaint asserts at least Claim 1. Compl. ¶34
• Independent Claim 1 of the ’971 Patent recites the following essential elements for a navigation device:
  • A setting unit configured to set waypoints and a destination.
  • A route searching unit configured to search for a route to the destination via the set waypoints.
  • A route guidance unit to carry out guidance along the searched route.
  • An output unit configured to output a message showing a deviation from a route leading to a first next waypoint, triggered only when the vehicle has deviated by a predetermined distance and is traveling on a route after said first next waypoint.
  • An input unit configured to input a user command indicating whether or not to travel via that first next waypoint in response to the outputted message.
• The complaint does not explicitly reserve the right to assert dependent claims.

III. The Accused Instrumentality

Product Identification

• The complaint names a series of Husqvarna robotic lawnmowers (Automowers) that utilize the Husqvarna Exact Positioning Operating System (EPOS), as well as the associated Automower Connect app, referred to as "Appdrive." Compl. ¶11

Functionality and Market Context

• The Accused Products are autonomous lawnmowers that navigate using satellite positioning (GPS with Real-Time Kinematic corrections for centimeter-level accuracy) rather than physical boundary wires. Compl. p. 14 A promotional diagram included in the complaint shows the system relying on satellites and a reference station to create a "Virtual boundary." Compl. p. 5 Users can define "work areas," "stay-out zones," and "transport paths" within the app, which guide the mower's operation. Compl. ¶17; p. 14 The complaint alleges these products represent a "growing and major area in lawn maintenance." Compl. ¶15

IV. Analysis of Infringement Allegations

’971 Patent Infringement Allegations

Identified Points of Contention

• Scope Questions: The infringement theory rests on mapping concepts from on-road vehicle navigation onto a robotic lawnmower. A potential dispute may arise over whether a "work area" boundary or a "stay-out zone" in a lawnmowing context constitutes a "waypoint" as that term is used in the ’971 Patent, which discloses embodiments related to car navigation on city streets.
• Technical Questions: A central question may be whether the accused system’s notification functionality meets the specific, sequential requirements of the "output unit" limitation. The claim requires the message to be triggered by a specific condition: the vehicle having deviated and now traveling on a route segment after the missed waypoint. The complaint provides evidence of general error messages (e.g., "Mower lifted," "Map problem") but does not detail whether these messages are triggered by the precise sequence of events recited in the claim. Compl. ¶42; p. 22

V. Key Claim Terms for Construction

The Term: "waypoint"

• Context and Importance: The applicability of the patent to the accused technology hinges on this term's scope. Defendant may argue that the patent's disclosure, focused on car navigation, limits "waypoints" to points along a road, whereas Plaintiff will likely argue for a broader definition covering any designated point on an autonomous route, such as the corner of a virtual boundary for a mower.
• Evidence for a Broader Interpretation: The plain language of the claim is not expressly limited to any particular type of vehicle or environment. The term itself is general.
• Evidence for a Narrower Interpretation: The patent specification and figures consistently depict on-road vehicle navigation. For example, Figure 7 shows a waypoint dialogue overlaid on a city map, which may be used to argue that the invention is meant to solve problems specific to that context. ’971 Patent, Fig. 7

The Term: "traveling along a route after said first next waypoint"

• Context and Importance: This phrase is the core of the claimed invention's novelty, distinguishing it from systems that react immediately upon deviation. Infringement will depend on whether the accused mower’s system can be shown to enter the specific state described: not merely having missed a waypoint, but actively proceeding on a subsequent portion of the planned route before a message is generated.
• Evidence for a Broader Interpretation: This could be interpreted to mean any movement in the general direction of the destination that is geographically beyond the location of the missed waypoint.
• Evidence for a Narrower Interpretation: The language suggests the device must still be executing a planned route, just a later part of it. The patent's flowchart shows this as a distinct condition checked after an initial deviation is detected, implying a specific logical state. ’971 Patent, Fig. 6-1, ST23

VI. Other Allegations

Indirect Infringement

• The complaint alleges inducement, stating that Defendant encourages and instructs customers to use the Accused Products in an infringing manner through instructions provided on its website and with the products. Compl. ¶¶45, 47-48

Willful Infringement

• The complaint bases its allegation of knowledge for indirect and willful infringement on, at a minimum, the filing of the complaint itself. Compl. ¶46

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

The resolution of this case may turn on two primary open questions:

1. A core issue will be one of definitional scope: can the term "waypoint," rooted in the patent's context of on-road vehicle navigation, be construed to cover the "work area" boundaries and "stay-out zone" markers used in the accused robotic mower’s virtual mapping system?
2. A key evidentiary question will be one of functional mismatch: does the accused product’s general-purpose error notification system perform the specific, multi-part logical function required by Claim 1—which requires detecting not only a deviation but that the vehicle is traveling past the missed waypoint before issuing a query about that specific waypoint—or is there a fundamental difference in technical operation between the accused system and the claimed invention?
