Case Timeline

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

U.S. Patent No. 11,297,216 - Electric shaver with imaging capability

• Patent Identification: U.S. Patent No. 11,297,216, "Electric shaver with imaging capability," issued April 5, 2022 (’216 Patent).

The Invention Explained

• Problem Addressed: The patent describes that achieving a good shave requires clear visibility of the skin, but direct eye contact is often impossible for areas like the face or legs. The use of a mirror can be inconvenient, may not be available, or may provide a poor-quality image in foggy or dark environments, with the user's own hand and the shaver potentially obstructing the view. (’216 Patent, col. 2:3-12).
• The Patented Solution: The invention integrates digital camera functionality into a portable, hand-held device like an electric shaver. This allows a close-up image of the shaving area to be captured and displayed on a display unit, which can be either integrated into the shaver or housed in a separate device. This provides the user with real-time visual feedback on the shaving activity without relying on a mirror. (’216 Patent, Abstract; col. 2:43-51).
• Technical Importance: The invention sought to merge digital imaging with personal grooming appliances to overcome longstanding visibility challenges, offering a self-contained solution for precision hair removal. (’216 Patent, col. 2:30-39).

Key Claims at a Glance

• The complaint asserts "one or more claims" and refers to "Exemplary '216 Patent Claims" without specifying them (Compl. ¶11). The following analysis is based on the patent's first independent claim, Claim 1.
• Claim 1 Elements:
  • A handheld device for capturing and displaying video data.
  • A first video camera that outputs first video data.
  • A second video camera that outputs second video data.
  • A multiplexer coupled to the cameras for multiplexing the video data into a multiplexed signal.
  • An antenna for transmitting a wireless signal.
  • A wireless transmitter coupled between the antenna and multiplexer.
  • A rechargeable battery to power the cameras, transmitter, and multiplexer.
  • A single portable and handheld casing housing the video cameras, wireless transmitter, and multiplexer, where the casing has two opposed exterior surfaces, with the first camera attached to the first surface and the second camera attached to the second surface.
• The complaint does not explicitly reserve the right to assert dependent claims.

III. The Accused Instrumentality

Product Identification

The complaint does not identify any accused products by name. It refers generally to "Defendant products identified in the charts incorporated into this Count below (among the 'Exemplary Defendant Products')" (Compl. ¶11). These charts were not filed with the complaint.

Functionality and Market Context

The complaint does not provide sufficient detail for analysis of the accused instrumentality's specific functionality or market context. It alleges only that the products "practice the technology claimed by the '216 Patent" (Compl. ¶16).

IV. Analysis of Infringement Allegations

The complaint references, but does not include, claim chart exhibits that purportedly compare the "Exemplary '216 Patent Claims to the Exemplary Defendant Products" (Compl. ¶16). The complaint alleges in a conclusory manner that these charts demonstrate that the accused products "satisfy all elements" of the asserted claims, either literally or under the doctrine of equivalents (Compl. ¶16). Without the specific charts or any factual detail in the complaint body, a tabular analysis is not possible. The core of the infringement allegation is a general assertion that Defendant makes, uses, sells, or imports products that practice the patented technology (Compl. ¶11).

No probative visual evidence provided in complaint.

Identified Points of Contention

• Evidentiary Questions: The complaint's reliance on an unprovided exhibit raises the primary question of what specific evidence Plaintiff will offer to show that the accused products contain each element of the asserted claims, such as two distinct video cameras, a multiplexer, and a wireless transmitter housed in a single casing.
• Scope Questions: The interpretation of "a single portable and handheld casing" could be a central issue. A potential dispute may arise over whether an accused product with a modular or multi-part construction meets this limitation.
• Technical Questions: A key technical question will be whether the accused products actually perform "multiplexing" as claimed. The complaint provides no facts on how the accused devices might combine data streams from multiple cameras, leaving open the question of whether their method of operation matches the claimed function.

V. Key Claim Terms for Construction

"single portable and handheld casing"

• Context and Importance: This term appears in independent Claim 1 and requires that multiple components—two video cameras, a wireless transmitter, and a multiplexer—be housed together. The definition is critical because if an accused product houses these components in physically separable or distinct modules, it may not infringe. Practitioners may focus on whether "single... casing" implies a unitary, non-separable body.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The specification describes embodiments where the display unit is a "separate device housed within a separate enclosure," which, by negative implication, suggests that when components are not described as separate, they are intended to be integrated within the main device's "casing." (’216 Patent, col. 2:65-67).
  • Evidence for a Narrower Interpretation: The drawings consistently depict the shaver as a monolithic, self-contained unit (’216 Patent, Figs. 5, 13, 21). An argument could be made that the figures, which show a single, integrated physical form, define the scope of the "single casing" as a unitary structure.

"multiplexer"

• Context and Importance: Claim 1 requires a "multiplexer" for combining signals from two cameras. The infringement analysis will depend on whether the accused product's method for handling two video streams meets the technical definition of multiplexing.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The claim language itself is broad, not specifying any particular type of multiplexing. This may support a construction that covers any component that combines two video data streams into one signal for transmission.
  • Evidence for a Narrower Interpretation: The specification explicitly describes two distinct types of multiplexing: Frequency Division Multiplexing (FDM) and Time Division Multiplexing (TDM) (’216 Patent, col. 18:1-14). A defendant might argue that the term "multiplexer" should be limited to these disclosed techniques or their equivalents, rather than covering any method of data combination.

VI. Other Allegations

Indirect Infringement

The complaint alleges induced infringement, stating that Defendant distributes "product literature and website materials" that instruct end users on how to use the accused products in a manner that allegedly infringes the ’216 Patent (Compl. ¶14).

Willful Infringement

The allegation of willfulness is based entirely on post-suit knowledge. The complaint asserts that the filing and service of the complaint and its attached (but unprovided) claim charts gave Defendant "actual knowledge of infringement" (Compl. ¶13).

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

• An Evidentiary Question of Infringement: Given the complaint’s lack of specific factual allegations, a central issue will be whether discovery reveals evidence that the accused products actually contain every element required by the asserted claims, particularly the presence of two distinct cameras and a "multiplexer" housed within a "single casing."
• A Definitional Question of Claim Scope: The case may turn on claim construction, specifically whether the term "single... casing" can be construed to read on devices that may have modular or physically distinct but interconnected components, or if it is limited to a unitary, monolithic body as depicted in the patent's figures.
• A Technical Question of Functionality: A key technical dispute will likely concern the term "multiplexer." The court will need to determine whether the accused products combine video data in a way that meets the legal definition of this term, or if there is a fundamental mismatch in technical operation compared to the methods disclosed in the patent.
