III. The Accused Instrumentality

Product Identification

The accused instrumentalities are Defendant’s medical carts, collectively referred to as the "Howard Products." (Compl. ¶14). This group includes the "Hi-Care" line (e.g., "Hi-Care E", "Hi-Care X"), the "Hi-PARADIGM" line, and the "Telecare Telemedicine Cart." (Compl. ¶14, 35).

Functionality and Market Context

The complaint alleges the Howard Products are mobile medical carts that compete directly with Plaintiff’s products. (Compl. ¶18). The accused functionalities, described broadly, include a height adjustment device, a tilting keyboard tray, a sliding mouse platform, and an automatic height adjustment feature based on stored user preferences. (Compl. ¶34, 36). The complaint states that Defendant advertises, markets, and sells these products on its website. (Compl. ¶15).

IV. Analysis of Infringement Allegations

The complaint references Exhibit K, titled “Amended Infringement Claim Charts,” which purports to show an element-by-element comparison of the Accused Products to the patents-in-suit. (Compl. ¶36). However, this exhibit was not provided. The narrative infringement theory is summarized below.

No probative visual evidence provided in complaint.

’668 Patent Infringement Allegations

The complaint alleges that the Howard Products directly infringe claims 3-5 of the ’668 Patent, either literally or under the doctrine of equivalents. (Compl. ¶41-42). The central allegation is that the accused carts possess a height adjustment device that includes "an actuator disposed above compartments on a portion of the work platform that projects in the forward direction," which tracks the language of the patent’s claims. (Compl. ¶34). The complaint does not specify which component of the accused carts constitutes the claimed "actuator" or its precise location.

’650 Patent Infringement Allegations

The complaint alleges that the Howard Products directly infringe claims 1-6 and 8 of the ’650 Patent. (Compl. ¶47). The infringement theory for this patent appears to center on the movable work surfaces of the accused carts. (Compl. ¶47; ’650 Patent, cl. 1). The complaint asserts that the Accused Products contain each element of the asserted claims but does not provide specific details regarding the structure or operation of the accused movable surfaces. (Compl. ¶48).

Identified Points of Contention

  • Scope and Structural Questions: For the ’668 Patent, a central question may be the construction of "actuator" and its precise location as claimed. The dispute may focus on whether a component in the accused carts meets the claim’s specific spatial requirement of being "disposed above the compartments" on a forward-projecting part of the work platform.
  • Technical and Functional Questions: For the ’650 Patent, a key question will be whether the accused carts have a "work surface" that is "movable relative to a remainder of the work platform" in the manner claimed. The analysis may depend on what components of the accused carts (e.g., a keyboard tray, a mouse platform) are deemed to be the "work surface" and whether their movement meets the claim limitations.

V. Key Claim Terms for Construction

  • Term: "actuator" (’668 Patent, claim 4)

  • Context and Importance: The infringement theory for the ’668 patent is tied to the presence and specific location of this element. Its construction will be critical in determining whether any component of the accused carts satisfies this limitation. Practitioners may focus on this term because its location is a precise, potentially dispositive, structural requirement.

  • Intrinsic Evidence for Interpretation:

    • Evidence for a Broader Interpretation: The claim uses the general term "actuator" without limiting it to a specific type (e.g., button, switch). The patent specification refers to the actuator controlling a "gas driven piston" (’668 Patent, col. 8:54-56) but does not appear to explicitly disclaim other types of actuators.
    • Evidence for a Narrower Interpretation: The specification discloses a specific embodiment where the actuator is a button (444) on the handle (360) that controls the driver. (’668 Patent, col. 9:1-5, Fig. 1). A party might argue that the term should be construed in light of this disclosed embodiment as a user-operated control mechanism.

  • Term: "work surface is movable relative to a remainder of the work platform" (’650 Patent, claim 1)

  • Context and Importance: This limitation defines a key functional aspect of the claimed invention. The dispute will likely concern whether features on the accused carts, such as a sliding keyboard tray, meet the definition of a "work surface" moving relative to the "work platform."

  • Intrinsic Evidence for Interpretation:

    • Evidence for a Broader Interpretation: The claim language is broad and does not specify the direction or manner of movement (e.g., sliding, pivoting).
    • Evidence for a Narrower Interpretation: The specification describes a specific embodiment of a "bi-directional work surface 350" that slides left and right in an arcuate path. (’650 Patent, col. 5:49-62). A party could argue that the scope of "movable" should be informed by this more specific disclosure.

VI. Other Allegations

  • Indirect Infringement: The complaint alleges induced infringement, stating that Defendant encourages and instructs customers to use the Accused Products in an infringing manner through instruction manuals, marketing, and training materials. (Compl. ¶83, 87). It also alleges contributory infringement, asserting the products are a material part of the inventions, have no substantial non-infringing uses, and are known by Defendant to be especially adapted for infringing use. (Compl. ¶94, 97).
  • Willful Infringement: The complaint pleads willful infringement based on knowledge of the patents-in-suit acquired upon service of the complaint. (Compl. ¶38, 44). The allegation is that Defendant's continued infringement after receiving notice constitutes willful and deliberate conduct. (Compl. ¶38).

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

  • A core issue will be one of structural mapping: Can the specific spatial limitations of the asserted claims, such as the location of the "actuator" in the ’668 patent, be mapped onto the physical structure of the accused Howard Products? The case may turn on a fact-intensive comparison of the accused device's components against the patent's precise language.
  • A second key question will be one of functional scope: Do the features of the accused carts, such as their keyboard trays or automatic adjustment systems, perform the specific functions required by the claims of patents like the ’650 and ’016 families, or is there a fundamental mismatch in their technical operation and capabilities?
  • A third central question will concern claim construction: How broadly will terms like "actuator," "work surface," and "automatically adjustable" be defined? The outcome of claim construction will likely determine the scope of the asserted claims and could be dispositive for the infringement analysis.
