U.S. Patent No. 10,828,612 - Locking and Unlocking a Blender, issued November 10, 2020

The Invention Explained

• Problem Addressed: The patent background identifies the risk of "accidental activation" of a portable blender, particularly when carried in a bag where objects might inadvertently press an activation button '612 Patent, col. 1:28-34
• The Patented Solution: The invention is a control system that implements distinct "locked" and "unlocked" modes of operation '612 Patent, abstract To transition from the safe, locked state to the operational, unlocked state, the user must perform a "first type of manual engagement" (e.g., pressing and holding the power button for a set duration), which is different from the "particular manual engagement" (e.g., a simple press of a start button) used to activate blending '612 Patent, col. 8:62-67 '612 Patent, col. 14:8-14
• Technical Importance: This dual-mode safety interlock is a key feature for a portable device with exposed blades, intended to prevent injury or mess during transport Compl. ¶15

IV. Analysis of Infringement Allegations

U.S. Patent No. 11,006,784 Infringement Allegations

Identified Points of Contention

• Scope Questions: A primary dispute may arise over the claim term "integral whole." The defense may argue that the accused base assembly, which appears to have a separable blade component as depicted in the complaint's own diagrams Compl. p. 18, does not form an "integral whole." The analysis will question whether this term applies to the motor/battery housing alone or to the entire base unit including the blade assembly.
• Technical Questions: The meaning of the battery being "not accessible to the user" raises a question of degree. The court may need to determine whether this means inaccessible without tools, or inaccessible under any circumstances, and what evidence shows the accused product meets that standard.

U.S. Patent No. 10,828,612 Infringement Allegations

Identified Points of Contention

• Scope Questions: The interpretation of "first type of manual engagement" versus a "particular manual engagement" may be a key issue. The defense could question whether a "press and hold" action is a distinct "type" of engagement from a simple press, or merely a durational variant of the same type of action.
• Technical Questions: What evidence demonstrates that rotation is truly "prevented" in the locked mode as required by the claim? The complaint relies on user manual instructions Compl. p. 37, which suggest this functionality, but the technical implementation within the accused device's circuitry would be the ultimate proof.

V. Key Claim Terms for Construction

From the '784 Patent

• The Term: "integral whole"
• Context and Importance: This term, applied to the "base assembly" in claim 1, is critical to the infringement analysis. Practitioners may focus on this term because the accused product's base appears to consist of a main housing and a separable blade assembly Compl. p. 18, raising the question of whether it can be considered a single integrated unit.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The specification states that components like the motor, battery, and control circuitry "may be integrated permanently into base assembly 11 such that base assembly 11 forms an integral whole" '784 Patent, col. 2:39-43 This could support a reading where the "integral whole" refers to the permanent integration of the electronic and power components within the housing, irrespective of a detachable mechanical element like the blades.
  • Evidence for a Narrower Interpretation: Figure 1 of the patent includes the "set of blades 13" within the bracketed area labeled "Base Assembly 11" '784 Patent, Fig. 1 This could support an argument that the patentee considered the blades part of the base assembly, and therefore a detachable blade system would preclude the assembly from being an "integral whole."

From the '612 Patent

• The Term: "a first type of manual engagement"
• Context and Importance: This term defines the user action required to transition the blender from its locked to its unlocked state. The case may depend on whether the accused "press-and-hold" action qualifies as a distinct "type" of engagement.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The specification provides a direct example: "the first type of manual engagement may include pressing the power button and holding the power button depressed for at least a specified duration" '612 Patent, col. 8:65-67 This provides strong support for Plaintiff's allegation that a durational press constitutes a "type" of engagement.
  • Evidence for a Narrower Interpretation: The specification also mentions "patterns of pressing and releasing the power button" as another example of an engagement type '612 Patent, col. 9:9-10 A defendant could argue that "type" implies a difference in pattern (e.g., single vs. double press) rather than merely duration, suggesting a press-and-hold is a variation, not a different type.

VI. Other Allegations

• Indirect Infringement: The complaint alleges both induced and contributory infringement for the '784, '612, and '891 patents. Inducement is primarily based on allegations that Defendant's user manuals, marketing, and online materials encourage and instruct end users to operate the Ninja Blast in an infringing manner Compl. ¶59 Compl. ¶77 Compl. ¶96
• Willful Infringement: Willfulness is alleged for all four asserted patents. The complaint bases this allegation on Defendant's status as a sophisticated market participant, alleged copying of the patented inventions, and alleged pre-suit knowledge of the '784, '612, and '891 patents since at least November 2, 2023. This alleged knowledge stems from an Information Disclosure Statement (IDS) that Defendant's counsel allegedly filed during the prosecution of its own design patent, which cited the patents-in-suit Compl. ¶44 Compl. ¶61 Compl. ¶79 Compl. ¶97

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

• A core issue will be one of definitional scope: can the term "integral whole" from the '784 patent, which describes the base assembly, be construed to read on a product where the blade assembly is mechanically separable from the main motor and battery housing?
• A second central issue will be one of evidentiary proof: can Plaintiff demonstrate that the accused blender's blade assembly is geometrically offset from the container's central axis by a distance falling within the specific percentage ranges (e.g., "between 5% and 40% of the blade diameter") required by the '891 patent's claims?
• A critical question for damages will be the imputation of knowledge: can the alleged knowledge of the patents-in-suit by Defendant's patent prosecution counsel, gained via an IDS, be legally imputed to the company as a whole to establish the subjective intent required for pre-suit willful infringement?
