Case Timeline

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

U.S. Patent No. 11,468,984 - Device, Method and Application for Establishing a Current Load Level

The Invention Explained

• Problem Addressed: The patent asserts that prior methods for determining a user's stress level were disadvantageous because they relied on "very few biometric data" categories, required users to wear special dedicated devices that could be a "nuisance," or demanded a "high level of additional effort" from the user, such as filling out questionnaires ('984 Patent, col. 2:4-34).
• The Patented Solution: The invention describes a system centered on a "mobile end unit" (e.g., a smartphone) that runs a "further application" to determine a user's stress level. This application ascertains a "multiplicity of biometric data" by uniquely combining information from two sources: (1) "signal data" from sensors integrated into the device (like a gyroscope or microphone) and (2) "use data" extracted from the user's interaction with other "available applications" on the device, such as telephony or SMS applications ('984 Patent, Abstract; col. 3:28-45). An evaluation unit then processes this combined data to establish a current load level ('984 Patent, col. 1:11-18).
• Technical Importance: The technology aims to provide a more reliable and less intrusive method of stress monitoring by leveraging the diverse sensors and software ecosystem already present on a user's personal mobile device, thereby avoiding the cost and comfort limitations of single-purpose monitoring hardware ('984 Patent, col. 2:46-53).

Key Claims at a Glance

• The complaint primarily asserts independent Claim 1 (Compl. ¶25).
• The essential elements of Claim 1 include:
  • A device comprising a "mobile end unit" which itself has at least one integrated sensor, a "plurality of available applications," and an evaluation unit.
  • The mobile end unit runs a "further application" that calculates biometric data from both sensor signals and "user data of said plurality of available applications."
  • The biometric data is divided into categories, and "category-specific load levels" are ascertained from features within each category.
  • The evaluation unit determines the user's overall current load level by applying a method carried out in a "network of artificial neural networks."
  • The calculation is supported by a "plurality of processors" operating in parallel and at least one "graphics card."
  • A "consolidated load level" is displayed to the user, which is derived from a combination of the category-specific load levels.

III. The Accused Instrumentality

Product Identification

The Withings ScanWatch and ScanWatch Horizon smartwatches, collectively referred to as the "Products" (Compl. ¶25).

Functionality and Market Context

The complaint identifies the accused instrumentalities as smartwatches. It makes the conclusory allegation that the Products "practice the technology claimed by the '984 Patent" and "satisfy all elements of the exemplary Claim 1" (Compl. ¶30). The complaint does not provide specific details regarding the technical operation of the accused smartwatches' stress-monitoring features, instead referring to claim chart exhibits that were not included with the complaint filing.

IV. Analysis of Infringement Allegations

The complaint references claim charts in Exhibits B and C to support its infringement allegations but does not include these exhibits in the provided filing (Compl. ¶30, ¶31). In their absence, the complaint's narrative theory is that the Withings ScanWatch and ScanWatch Horizon smartwatches practice the technology of the '984 Patent and meet all limitations of at least Claim 1 (Compl. ¶30). No specific factual allegations are made in the body of the complaint to map particular product features to individual claim elements.

No probative visual evidence provided in complaint.

Identified Points of Contention

• Scope Questions: Claim 1 recites a "mobile end unit" with a "plurality of available applications," from which "user data" is extracted. The patent specification gives examples like telephony and SMS applications ('984 Patent, col. 3:51-63). A potential point of dispute is whether the accused smartwatches and their more specialized application ecosystems fall within the scope of a "mobile end unit" as contemplated by the patent, or if the term is limited to devices like smartphones with broad, multi-purpose communication apps.
• Technical Questions: Claim 1 requires a specific and complex computational backend, including a "network of artificial neural networks" and calculation support from a "graphics card." A central factual question for the court will be whether the accused Withings products actually implement this architecture to analyze user data. The complaint provides no evidence on this point, suggesting it will be a primary focus of technical discovery. Another question is whether the accused products derive data from a user's interaction with a "plurality of available applications," as distinct from merely collecting data from physiological sensors.

V. Key Claim Terms for Construction

"user data of said plurality of available applications"

• Context and Importance: This term is critical for distinguishing the claimed invention from prior art that may have only used sensor data. Infringement of this element will depend on whether the accused smartwatches are shown to collect and analyze data derived from a user's interaction with multiple software applications on the device, beyond just raw sensor outputs.
• Intrinsic Evidence for a Broader Interpretation: The patent states that an "available application" is one that is "installed and executable on the mobile terminal, such as telephony, SMS, MMS, chat applications and/or browser applications" ('984 Patent, col. 2:62-65). This language could support a broad reading that covers data from any application on the device.
• Intrinsic Evidence for a Narrower Interpretation: The specification's primary examples for this type of data are from communication-centric applications ('984 Patent, col. 3:46-63). A party could argue that the term should be limited by these examples to data reflecting social interaction, rather than data from any utility or system application.

"network of artificial neural networks"

• Context and Importance: This limitation requires a specific type of machine learning architecture. The plaintiff's ability to prove infringement hinges on demonstrating that the accused products employ this specific computational method, not just a generic algorithm for stress analysis.
• Intrinsic Evidence for a Broader Interpretation: A party may argue the plain meaning of the term covers any system using two or more interconnected neural networks to perform the claimed function.
• Intrinsic Evidence for a Narrower Interpretation: The specification discloses specific, advanced implementations like a "Deep Belief Network or a convolutional deep belief network" and a "multilayer perceptron network" ('984 Patent, col. 6:40-41; col. 21:48-50). A party may argue these embodiments inform and limit the scope of the broader term to similarly complex architectures.

VI. Other Allegations

• Indirect Infringement: The complaint alleges inducement of infringement, stating that the Defendant distributes "product literature and website materials" that instruct end users to operate the products in an infringing manner (Compl. ¶28). The complaint also makes a conclusory allegation of contributory infringement (Compl. ¶25).
• Willful Infringement: The basis for willfulness is alleged post-suit knowledge. The complaint asserts that service of the complaint itself provides "actual knowledge" of infringement and that any continued infringement thereafter is willful (Compl. ¶27, ¶28).

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

• A core issue will be one of definitional scope: can the term "mobile end unit," which the patent describes in the context of a smartphone with a diverse communication-app ecosystem, be construed to read on the accused smartwatches with their different operating systems and application sets?
• A key evidentiary question will be one of technical implementation: does discovery reveal that the accused products employ the specific computational architecture required by Claim 1, including a "network of artificial neural networks" with calculation support from a "graphics card," or is there a fundamental mismatch in the underlying technology?
• A central question of infringement will be the source of data: can the plaintiff prove that the accused products calculate stress levels using not only data from integrated sensors but also "user data" derived from a "plurality of available applications," as distinctly required by the claim?
