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

U.S. Patent No. 9,272,667 - “Automated Retractable Vehicle Step”

  • The Invention Explained:
    • Problem Addressed: The patent’s background describes that aftermarket installation of automated retractable step assists is often complex and expensive, typically requiring skilled technicians to perform modifications such as cutting, splicing, or tapping into existing vehicle wiring, particularly in or around the vehicle doors (US9272667B2, col. 1:47-54).
    • The Patented Solution: The invention is a "plug-and-play" step assist system designed to simplify installation. It includes a vehicle interface that connects to a pre-existing electronics port on the vehicle, such as an On-Board Diagnostic (OBD) port, to receive data like door open/closed status. A controller then uses this data to automatically deploy or retract the step, thereby avoiding direct modification of the vehicle's door wiring (US9272667B2, col. 8:24-34; Fig. 2A).
    • Technical Importance: This approach significantly reduced the complexity, cost, and risk of installing aftermarket automated running boards, making the technology more accessible to consumers for do-it-yourself installation (US9272667B2, col. 1:47-54).
  • Key Claims at a Glance:
    • The complaint asserts independent Claim 1 (Compl. ¶31).
    • The essential elements of Claim 1 are:
      • A powered retractable vehicle step assist system.
      • A stepping member movable between a retracted and a deployed position.
      • At least one support member connected to the stepping member.
      • A motor operably coupled to the support member to effectuate movement.
      • A vehicle interface configured to connect with an already existing electronics port of the vehicle and to electronically receive data generated by existing vehicle electronics.
      • A controller configured to use the received data to cause the motor to move the stepping member.
      • The received data comprises door opened/closed status information originating from door electronics that do not incorporate any wireless sensors.
    • The complaint alleges infringement of "at least Claim 1," reserving the right to assert other claims (Compl. ¶31).

U.S. Patent No. 9,527,449 - “Controlling a Powered Vehicle Step”

  • The Invention Explained:
    • Problem Addressed: The patent identifies the technical challenge of integrating aftermarket accessories with a vehicle's native electronics without invasive modifications, such as splicing into wiring near the doors (US9527449B2, col. 1:22-38).
    • The Patented Solution: The patent claims a method for controlling a powered vehicle step by electronically obtaining door status information directly from a vehicle's digital communication bus (such as a CAN bus accessed via an OBD port). This digital information is then processed by an algorithm in a controller to determine when to command the step's motor to deploy or retract the stepping deck (US9527449B2, Abstract; col. 2:4-10).
    • Technical Importance: This method leverages a vehicle's standardized digital data stream for control signals, which may provide a more reliable and less installation-intensive solution than tapping into analog wiring harnesses (US9527449B2, col. 2:11-14).
  • Key Claims at a Glance:
    • The complaint asserts independent Claim 12 (Compl. ¶46).
    • The essential elements of Claim 12 are:
      • A method of controlling an after-market powered vehicle step system.
      • Electronically obtaining door status information from a digital communication bus of the vehicle.
      • Electronically processing the door status information according to an algorithm to determine if movement of the stepping deck is appropriate.
      • Commanding a motor to cause movement of the stepping deck between a retracted and a deployed position.
    • The complaint alleges infringement of "at least Claim 12," reserving the right to assert other claims (Compl. ¶46).

U.S. Patent No. 9,511,717 - “Automated Retractable Vehicle Step”

  • Technology Synopsis: This patent describes a vehicle step assist system intended to reduce installation complexity. The system uses a vehicle interface designed to connect to an existing electronics port, such as an OBD-II port, to receive data generated by the vehicle's electronics. A controller processes this data to issue commands to a step unit, automating its deployment and retraction without requiring installers to modify door wiring (US9511717B2, Abstract; col. 1:43-54).
  • Asserted Claims: Claim 9 (Compl. ¶61).
  • Accused Features: The complaint accuses the "Southern Truck GM Electric Step" of infringing by including a step unit, a vehicle interface that connects to the vehicle's OBD-II port to receive data, and a controller that uses this data to command the step unit's operations (Compl. ¶63-68).

  • Identified Points of Contention:
    • Scope Questions: The analysis may focus on whether obtaining data from the OBD-II port constitutes obtaining information "from a digital communication bus" as understood in the art and defined by the patent.
    • Technical Questions: A potential dispute may arise over whether the accused product's control logic performs the claimed step of "processing the door status information according to an algorithm", or if it constitutes a simpler, non-algorithmic function.

V. Key Claim Terms for Construction

  • The Term: "already existing electronics port" (’667 Patent, Claim 1)

  • Context and Importance: This term is central to the patent’s asserted novelty of a simplified, "plug-and-play" installation. Infringement of the ’667 Patent hinges on whether the accused product's connection to the vehicle’s OBD-II port falls within the scope of this term.

  • Intrinsic Evidence for Interpretation:

    • Evidence for a Broader Interpretation: The specification states that the system "plugs into, connects with, or otherwise interfaces with an existing vehicle connection to obtain door status" and that some embodiments "plug into or otherwise interface with an on-board diagnostic (OBD) port, for example" (US9272667B2, col. 1:49-54). The use of "for example" suggests OBD is illustrative, not exhaustive.
    • Evidence for a Narrower Interpretation: The detailed descriptions and figures consistently depict the OBD port as the primary embodiment of the "electronics port" (US9272667B2, Fig. 2A, 3; col. 10:35-37). A party could argue that the invention, as disclosed, is focused on this specific, standardized port.
  • The Term: "digital communication bus" (’449 Patent, Claim 12)

  • Context and Importance: This term defines the source of the control signal for the claimed method. The infringement allegation rests on the premise that the data obtained from the OBD-II port is from such a bus.

  • Intrinsic Evidence for Interpretation:

    • Evidence for a Broader Interpretation: The specification explains that "the system according to some aspects obtains the information via one or more existing communication buses of the vehicle, e.g., via a digital interface such as a serial data link" and explicitly identifies the OBD port as an interface for such a bus (US9527449B2, col. 2:1-6).
    • Evidence for a Narrower Interpretation: The complaint does not provide sufficient detail for analysis of intrinsic evidence that may support a narrower interpretation. A party might attempt to distinguish between the physical port and the underlying bus itself, but the specification appears to treat the port as the access point to the bus.

VI. Other Allegations

  • Indirect Infringement: The complaint alleges both induced and contributory infringement for all four asserted patents. Inducement is based on Defendant allegedly providing installation instructions that guide end-users to install and operate the Accused Products in an infringing manner (Compl. ¶41, ¶56). Contributory infringement is based on allegations that the Accused Products are a material part of the inventions, are not staple articles of commerce, and are known by Defendant to be especially adapted for infringement (Compl. ¶42, ¶57).
  • Willful Infringement: While not pleaded as a separate count, the complaint lays a foundation for willfulness by alleging pre-suit knowledge. It asserts that Defendant is a distributor of Plaintiff's patented "PowerStep" products and was "necessarily aware" of them (Compl. ¶28). The complaint points to Defendant's own website, which allegedly features a video advertising Plaintiff's product with the text "[p]atented design," as evidence of this knowledge (Compl. ¶29).

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

  • A core issue will be one of definitional scope: can the claim terms "already existing electronics port" and "digital communication bus" be construed to cover the vehicle's standard OBD-II port, which the Accused Products allegedly use to receive control signals? The outcome of claim construction on these terms will be central to the direct infringement analysis for the ’667 and ’449 patents.
  • A key evidentiary question will be one of technical operation: what is the precise nature of the data the accused system receives from the OBD-II port, and how does its controller process that data? The case will require factual determinations as to whether the system's function meets specific claim limitations, such as receiving data "originating from door electronics that do not incorporate any wireless sensors" and "processing...according to an algorithm."
  • A third central question will concern the defendant's state of mind: does the evidence that Defendant also distributes and advertises Plaintiff's patented products establish the requisite knowledge and intent to support claims for indirect infringement and, potentially, willful infringement?
