IV. Analysis of Infringement Allegations

'784 Patent Infringement Allegations

Claim Element (from Independent Claim 1)	Alleged Infringing Functionality	Complaint Citation	Patent Citation
a base assembly ... integrated such that the base assembly forms an integral whole;	The Ninja Blast integrates the motor, rechargeable battery, charging interface, power button, and mechanical coupling into a single base unit.	¶73	col. 4:23-26
a rechargeable battery ... not accessible to the user during charging, blending, cleaning of the blender, and storage of the blender;	The Ninja Blast's 7.4V rechargeable battery is integrated into the base and is not user-accessible.	¶69	col. 4:8-12
a standardized charging interface ... wherein the standardized charging interface is a universal serial bus (USB) port configured to receive an electrical connector for charging the rechargeable battery;	The Ninja Blast includes a universal serial bus (USB-C) port for charging its battery.	¶70	col. 4:12-15
a second mechanical coupling disposed at or near the proximal end, wherein the second mechanical coupling is configured to engage the first mechanical coupling of the base assembly to couple the base assembly to the container assembly;	The blending vessel of the Ninja Blast has a mating coupling structure that engages the corresponding coupling on the base to form the assembled blender.	¶75	col. 3:55-59
control circuitry is configured to ... control the electrical motor to drive the rotation of the set of two or more pointed blades and thereby blend the foodstuffs.	The Ninja Blast's control circuitry is activated by a user to control the motor and blend ingredients once the container is properly attached to the base.	¶76	col. 4:40-45

• Identified Points of Contention:
  • Scope Questions: A potential dispute may arise over the term "integral whole". Defendant may argue that its base assembly, while self-contained, does not meet the specific level of integration required by the claim if, for example, its components can be disassembled for service, raising the question of whether "integrated" implies a permanent, inseparable construction.
  • Technical Questions: The complaint's allegations are supported by detailed product images. An issue for the court could be whether the accused "rechargeable battery" is technically "not accessible to the user" under all reasonable circumstances, a factual question that may depend on the difficulty of disassembly.

'612 Patent Infringement Allegations

Claim Element (from Independent Claim 1)	Alleged Infringing Functionality	Complaint Citation	Patent Citation
a power interface configured to be engaged manually by the user, wherein the power interface includes a power button	The Ninja Blast has a power button that is manually engaged by the user. An annotated diagram shows this button.	¶90	col. 8:55-59
wherein the power interface is configured to facilitate transitions between at least two modes of operation ... a locked mode ... and an unlocked mode...	The Ninja Blast user manual instructs the user to press the power button to turn the unit "ON," which illuminates the Start/Stop button, thereby transitioning it to an unlocked mode.	¶91	col. 9:11-16
wherein the power interface is further configured, during the unlocked mode of operation, to activate the rotation of the blending component responsive to a particular manual engagement of the power interface by the user;	In the unlocked mode, the user presses a separate "Start/Stop button" to begin a blend cycle. The complaint alleges this button is part of the overall power interface.	¶91	col. 9:16-20
control circuitry is configured to ... control operation of the power interface to enable a first transition from the locked mode of operation to the unlocked mode of operation, wherein the first transition occurs responsive to a first type of manual engagement...	The user must perform a first type of engagement (holding the power button) to transition from locked to unlocked mode.	¶95	col. 10:28-32
control circuitry is configured to ... selectively allow or prevent the rotation of the blending component based on whether the blender is currently operating in the locked mode of operation or the unlocked mode of operation...	Pressing the Start/Stop button causes rotation only when the Ninja Blast is in the unlocked mode; it has no effect in the locked mode.	¶96	col. 10:38-48

• Identified Points of Contention:
  • Scope Questions: A significant dispute is likely to center on the claim term "power interface". The claim requires "the power interface" to both facilitate mode transitions and activate rotation. The accused product uses two distinct buttons: a "Power Button" for modes and a "Start/Stop Button" for activation Compl. ¶91 This raises the question: does the claimed "power interface" refer to a single control element that must perform both functions, or can it be construed as a system of controls that includes both the Power and Start/Stop buttons?
  • Technical Questions: What evidence establishes that the accused product's two-button system (power-on/lock and blend-start) performs the same function in substantially the same way as the system described in the patent, which may be interpreted as using a single power interface for both mode switching and activation? A user manual excerpt shows separate "POWER BUTTON" and "START/STOP BUTTON" controls Compl., p. 40

V. Key Claim Terms for Construction

• Term from '784 Patent: "integral whole"

  • Context and Importance: This term appears in claim 1, which requires that the base assembly's core components (motor, battery, etc.) are "integrated such that the base assembly forms an integral whole." The enforceability of the claim against products with varying degrees of component separability will depend on this term's construction.
  • Evidence for a Broader Interpretation: Plaintiff may argue the term simply means the components are contained within a single, non-modular housing intended to function as a unified device, consistent with the patent's overall goal of a compact, portable unit '784 Patent, col. 3:1-10
  • Evidence for a Narrower Interpretation: Defendant may argue the term requires a higher degree of physical and electronic integration, where components are permanently "embedded" and not merely co-located '784 Patent, col. 3:17 They might contend that if their product can be disassembled for service, it does not form an "integral whole" in the claimed sense.

• Term from '612 Patent: "power interface"

  • Context and Importance: Claim 1 recites a "power interface" that performs both mode-switching and blend-activation functions. As the accused product uses two separate buttons for these functions, the definition of this term is central to the infringement analysis.
  • Evidence for a Broader Interpretation: Plaintiff may point to the specification, which describes the "power interface 29" as part of the overall user interface and depicts it as a general region on the blender base '612 Patent, Fig. 1 This could support an interpretation where the "power interface" is a system of user controls, which would include both the accused product's power and start/stop buttons.
  • Evidence for a Narrower Interpretation: Defendant may argue that because claim 1 explicitly states the "power interface includes a power button," the interface and the button are functionally synonymous for the purposes of the claim. The specification also describes user engagement with "the power button" to cause transitions, potentially tying the interface's function specifically to that single button '612 Patent, col. 8:59-65

VI. Other Allegations

• Indirect Infringement: The complaint alleges inducement of infringement for all four patents. The allegations are based on Defendant encouraging and instructing both end-users and retailers to infringe. For end-users, the complaint cites user manuals and guides that allegedly instruct on the infringing use of the product (Compl. ¶¶79; Compl. ¶99). For retailers, the complaint points to Defendant's sales and distribution of the Accused Products to companies like Walmart, Best Buy, and Amazon, who then directly infringe by selling them (Compl. ¶¶78; Compl. ¶98).
• Willful Infringement: The complaint makes detailed allegations of willful infringement based on both pre-suit and post-suit knowledge. The claim of pre-suit knowledge is supported by allegations that Defendant received a confidential memorandum disclosing the patents in April 2022 and, more significantly, that Defendant's own patent counsel cited the '784, '612, and '891 patents in an Information Disclosure Statement during the prosecution of its own design patent in November 2023 Compl. ¶¶57-58 Post-suit knowledge is based on the service of the original complaint on March 4, 2026 Compl. ¶63

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

• A core issue will be one of definitional scope: can the term "power interface" in the '612 patent, which is configured to both switch modes and activate blending, be construed to read on the accused product's two-button system where these functions are separated between a "Power Button" and a "Start/Stop Button"?
• A second key question will be one of technical evidence: for the '891 "offset blade" patent, the analysis will turn on whether Plaintiff can produce factual evidence, likely through expert analysis, demonstrating that the rotational axis of the Ninja Blast's blade assembly is offset by a distance that falls within the specifically claimed range of "between 5% and 40% of the blade diameter."
• Finally, the case raises a significant question of culpability and damages: given the complaint's strong evidence of pre-suit knowledge, including an IDS filed by Defendant's own counsel, a central battleground will likely be willfulness. The court's determination on this issue could substantially impact potential damages, raising the stakes beyond a simple finding of infringement.
