U.S. Patent No. 7,594,668 - “Medical Cart, Medication Module, Height Adjustment Mechanism, and Method of Medication Transport”
- Patent Identification: U.S. Patent No. 7594668, “Medical Cart, Medication Module, Height Adjustment Mechanism, and Method of Medication Transport,” issued September 29, 2009.
The Invention Explained
- Problem Addressed: The patent’s background section states that existing medical carts used for Electronic Medical Administration Records (EMAR) are often not ergonomically designed, leading to chronic back pain among nurses, and suffer from a lack of work surface and storage space, hindering efficient medication administration (’668 Patent, col. 1:43-54).
- The Patented Solution: The invention is a mobile medical cart with a height adjustment mechanism that allows a user to raise or lower a work platform for use while either sitting or standing (’668 Patent, col. 2:11-18). The work platform is described as having multiple components, including a separate laptop platform and a work surface that can move forward/rearward and left/right, respectively, to enhance ergonomic access and utility (’668 Patent, col. 4:28-35, col. 4:42-53).
- Technical Importance: The design addresses the need for more adaptable and ergonomic point-of-care equipment in hospitals, aiming to reduce both physical strain on staff and the potential for medication errors by improving workflow (’668 Patent, col. 1:20-24, col. 2:4-8).

- Identified Points of Contention:
- Scope Questions: The infringement case for the ’650 Patent may turn on the construction of "disposed above." Does this term require the actuator to be directly on top of a compartment, or can it mean in a position of general vertical superiority? The precise spatial relationship between the actuator, compartment(s), and the "portion of the work platform that projects" will be a central dispute.
- Technical Questions: The complaint's infringement allegations are conclusory and lack specific factual support demonstrating how the ENV and EVA carts operate. A key question is whether discovery will produce evidence that the accused height adjustment mechanism is, in fact, an "actuator" that is "disposed above" a "compartment" as those terms are defined by the patents, or if there is a fundamental mismatch in the accused products' mechanical structure and operation.
V. Key Claim Terms for Construction
The Term: "actuator"
Context and Importance: This term appears in the independent claims of both asserted patents and is a focus of the complaint's infringement theory (Compl. ¶30). Its definition will determine what type of height-adjustment control mechanisms fall within the scope of the claims. Practitioners may focus on this term because its construction could either limit the claims to the specific embodiments shown or broaden them to cover a wider range of mechanical or electromechanical systems.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The term is used generally to refer to a component for "controlling the driver" (’668 Patent, col. 13:54). This functional language may support a construction not limited to a specific structure.
- Evidence for a Narrower Interpretation: The specification consistently describes the actuator as a physical "button 444" connected to a gas-driven piston driver (’668 Patent, col. 9:1-2, Fig. 10B). This may support an argument that the term is limited to a manually-pressed button controlling a pneumatic or hydraulic system.
The Term: "disposed above"
Context and Importance: This spatial term from claim 1 of the ’650 Patent is critical for defining the required location of the actuator relative to the compartment. The entire infringement allegation hinges on this specific geometric arrangement (Compl. ¶30). The case may depend on whether the accused carts' actuator placement meets this limitation.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The specification does not provide an explicit definition. A party could argue for a plain and ordinary meaning that encompasses any position that is vertically higher than the compartment, not necessarily in direct contact or alignment.
- Evidence for a Narrower Interpretation: Figure 1 shows the handle (360), which contains the actuator button (444 in other figures), located physically above the medication compartments (530). A party could argue that "disposed above" requires the arrangement depicted in the figures, where the actuator is part of a handle structure that sits higher than and overhangs the front-facing compartments. The claim also requires the actuator to be "on the portion of the work platform," potentially narrowing its location further (’650 Patent, col. 14:51-53).
VI. Other Allegations
- Indirect Infringement: The complaint alleges induced infringement under 35 U.S.C. § 271(b), asserting that Defendant encourages and instructs customers on infringing uses through "instruction manuals, marketing materials, and/or training materials" (Compl. ¶53). It also pleads contributory infringement under § 271(c), alleging the accused carts are a material part of the invention, are not staple articles of commerce, and have no substantial non-infringing uses (Compl. ¶60, 64).
- Willful Infringement: Willfulness is alleged based on both pre-suit and post-suit knowledge. The complaint alleges Defendant had actual knowledge of the patents-in-suit as of an April 25, 2022 notice letter (Compl. ¶27). It further alleges that Defendant continued to infringe after receiving this notice and after the complaint was filed, constituting "willful and deliberate acts of infringement" (Compl. ¶19, 34).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of definitional scope: can the phrase "actuator disposed above the compartment," which is central to the infringement allegation, be construed broadly enough to read on the specific mechanical and spatial configuration of the accused ENV and EVA carts? The resolution of this claim construction dispute may be dispositive.
- A second key issue will be evidentiary sufficiency: the complaint provides conclusory allegations of infringement without specific, publicly available evidence mapping the accused products to the claim limitations. The case will likely turn on whether the factual evidence produced in discovery substantiates the plaintiff's theory, particularly regarding the internal mechanics and precise arrangement of the height adjustment system in Defendant's products.
