Case Timeline

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

U.S. Patent No. 8,915,823 - "System And Method For Processing Information"

The Invention Explained

• Problem Addressed: The patent describes a market where exercise tracking systems were expensive, incompatible with common gym equipment, and often required cumbersome manual data entry, which was prone to error (’823 Patent, col. 1:45-col. 2:24).
• The Patented Solution: The invention proposes a system to automate the capture and transfer of exercise data. It describes an interface device or "docking station" that connects to an exercise machine (e.g., via a serial port) and allows a user to transfer workout data to a separate, portable storage device, such as a USB flash drive. This data can then be uploaded to a website for analysis, comparison, and competition with other users (’823 Patent, Abstract; col. 4:5-25).
• Technical Importance: The invention aimed to provide a universal and affordable way to bridge the data gap between various exercise machines and a user's personal data log, overcoming proprietary hardware limitations of the era (’823 Patent, col. 3:50-54).

Key Claims at a Glance

• The complaint asserts at least independent claim 1 (Compl. ¶51).
• Essential elements of claim 1 include:
  • A method for managing communications between a cardio exercise device and a portable storage device.
  • Establishing a communication link between the exercise device and the portable storage device.
  • Transferring data between them via the link.
  • Generating workout data via a processor that receives sensor data from both a body sensor and a cardio exercise device sensor.
  • Communicating the workout data to the portable storage device for storage.

U.S. Patent No. 11,185,738 - "System And Method For Processing Information"

The Invention Explained

• Problem Addressed: As a continuation of the family including the ’823 patent, this patent addresses the same problems of incompatibility and manual data entry in exercise tracking (’738 Patent, col. 1:22-col. 2:24).
• The Patented Solution: The solution evolves from a simple docking station to a system centered on a "handheld biometrically secured personal content device" (e.g., a smartphone or similar device). This device establishes a first communication link with an exercise machine or body monitor and a second link with a remote website. The system uses a biometric sensor (e.g., fingerprint) to securely associate the workout data with the specific user performing the exercise, enhancing data integrity (’738 Patent, Abstract; col. 13:33-43).
• Technical Importance: This approach modernizes the data transfer concept by integrating it into a personal mobile device and adding a layer of biometric security to verify the identity of the person exercising (’738 Patent, col. 12:40-45).

Key Claims at a Glance

• The complaint asserts at least independent method claim 15 (Compl. ¶67).
• Essential elements of claim 15 include:
  • Managing communications between a handheld biometrically secured personal content device, a remote website, and an exercise machine/body monitor.
  • Establishing a first link (device to machine/monitor) and a second link (device to website).
  • Generating exercise session data from sensors.
  • Transferring and storing the data on the handheld device.
  • Uploading the data to the remote website.
  • Protecting the exercise data "with biometric data security of the person who performed the workout using a biometric sensor."
  • Displaying the data on the handheld device.

U.S. Patent No. 11,252,235 - "System And Method For Processing Information"

• Technology Synopsis: This patent describes a self-contained biological monitoring device (like a smartwatch) with a sensor to obtain heart rate data. A processor within the device analyzes this data to detect irregularities (e.g., abnormal heart rhythm), generates resultant data such as a health notification, and can display, store, and communicate this information to an external, biometrically-secure mobile device (’235 Patent, Abstract; col. 13:1-41).
• Asserted Claims: The complaint asserts at least independent claim 1 (Compl. ¶83).
• Accused Features: The complaint alleges that the biological monitoring capabilities of the Accused Products, specifically those that obtain, process, analyze, and display heart rate data, infringe this patent (Compl. ¶84).

III. The Accused Instrumentality

Product Identification

The complaint names a wide range of smartwatches and wearables sold under the FOSSIL, SKAGEN, MISFIT, MICHAEL KORS, DIESEL, and PUMA brands, including the FOSSIL Gen 6, Gen 5, and Hybrid series. The "Accused Products" also include associated software, such as the Fossil Smartwatches App, Fossil Wellness App, and cloud-based servers that work in conjunction with the watches (Compl. ¶¶ 36-37).

Functionality and Market Context

The Accused Products are alleged to provide features including workout tracking, heart rate monitoring, SpO2 (blood oxygen) monitoring, sleep tracking, and VO2 max monitoring (Compl. ¶41). A marketing screenshot from Fossil's website presents a feature comparison chart for its Gen 6, Gen 5E, and Gen 5 LTE models, highlighting capabilities such as heart rate tracking, SpO2, and VO2 Max (Compl. p. 9). The complaint alleges these features are central to the products' popularity and sales, and that the devices communicate with third-party smartphones and tablets to transfer and display health-related data (Compl. ¶¶ 42, 44). Another screenshot shows the "Wellness Central" screen in the Fossil app, which provides "a complete overview of health metrics, including workouts, sleep and more—all on one screen" (Compl. p. 12).

IV. Analysis of Infringement Allegations

’823 Patent Infringement Allegations

• Identified Points of Contention:
  • Scope Questions: A primary question is whether the term "portable storage device," which the patent specification exemplifies as a USB flash drive (’823 Patent, col. 4:28-34), can be construed to read on an active, processing device like a smartwatch. The complaint's theory appears to require the smartwatch to be both the "cardio exercise device" (in part) and the "portable storage device" simultaneously.
  • Technical Questions: The patent describes a specific architecture where a "docking station" mediates between an exercise machine and a portable storage device. The complaint does not identify a distinct "docking station" component in the accused system. A key question for the court will be whether the integrated system of the smartwatch (sensors, processor, memory, communication modules) performs the steps of the claimed method, even if its architecture differs from the patent's primary embodiment.

’738 Patent Infringement Allegations

• Identified Points of Contention:
  • Scope Questions: The definition of "protect... with biometric data security" will be critical. The patent mentions a fingerprint sensor to "associate the user... with the exercise session data" (’738 Patent, col. 13:38-43). The complaint alleges that using a heart rate monitor for tracking fulfills this "security" function. The court will have to determine whether "biometric data security" requires an authentication function (like a fingerprint lock) or if merely associating data with a user via a biometric measurement (like heart rate) is sufficient.
  • Technical Questions: Does using a heart rate sensor, which is primarily a data-gathering tool for fitness metrics, perform the function of "protecting" data in the manner required by the claim? This raises a factual question about the technical operation of the accused devices versus the claimed security function.

V. Key Claim Terms for Construction

• Term (from ’823 Patent): "portable storage device"

  • Context and Importance: The complaint's infringement theory for the '823 patent hinges on construing this term to cover a smartwatch. The viability of the infringement claim may depend on whether this term is limited to passive storage media or can encompass an active processing device like a smartwatch.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: Claim 1 recites the device is for "storage," a function a smartwatch performs. The claim does not explicitly limit the device to being passive or preclude it from having other capabilities.
    • Evidence for a Narrower Interpretation: The specification repeatedly provides "a portable USB flash drive" as the primary example (’823 Patent, col. 4:28-29; 4:51-52). The figures show a distinct USB drive separate from the exercise equipment, suggesting a device whose main purpose is data transport, not data creation or processing (’823 Patent, Fig. 1A).

• Term (from ’738 Patent): "protect... with biometric data security... using a biometric sensor"

  • Context and Importance: This term is central to the infringement allegation for the ’738 Patent. Practitioners may focus on this term because its construction will determine whether simply using a heart-rate sensor for fitness tracking meets the claim's "security" requirement, or if a more explicit authentication function is needed.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The claim language requires using a biometric sensor to provide "biometric data security of the person who performed the workout." An argument could be made that continuously tracking a unique biometric like heart rate serves to confirm the identity of the wearer throughout the workout, thereby providing a form of data security through association.
    • Evidence for a Narrower Interpretation: The specification explicitly discloses a "fingerprint sensor" as an example of the biometric sensor (’738 Patent, col. 16:44-45). This suggests a security function related to authentication or access control, rather than simple data collection. The use of the word "protect" may imply guarding against unauthorized access or tampering, a function not typically performed by a heart rate sensor.

VI. Other Allegations

• Indirect Infringement: For all three patents, the complaint alleges induced infringement, stating that Defendants’ advertising, user guides, and other instructions direct end-users to operate the Accused Products in an infringing manner (Compl. ¶¶ 57, 73, 89). Contributory infringement is also alleged, based on the theory that the Accused Products contain special features (e.g., the specific methods of data collection and processing) that are a material part of the invention and have no substantial non-infringing use (Compl. ¶¶ 58, 74, 90).
• Willful Infringement: The complaint alleges Defendants had knowledge of the ’823 patent and its infringement as of July 12, 2019 (Compl. ¶56). For the later-issued ’738 and ’235 patents, it alleges knowledge as of their respective issue dates, but also asserts knowledge of the "’738 patent’s portfolio" dating back to the same July 12, 2019 date (Compl. ¶¶ 72, 88). Willfulness is further supported by the allegation that Defendants have a policy of not reviewing patents of others, constituting willful blindness (Compl. ¶¶ 59, 75, 91).

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

• A core issue will be one of definitional scope: can the term "portable storage device," rooted in the '823 patent's description of a passive USB drive, be construed to cover an active, data-processing smartwatch? The outcome of this claim construction will likely be dispositive for the infringement allegation on the oldest patent in the family.
• A second central question will be one of functional interpretation: does the term "protect ... with biometric data security" in the '738 patent require an access control or authentication function (like a fingerprint lock), or is the function met by merely associating workout data with a user via a continuously-monitored biometric like heart rate?
• Finally, a key evidentiary question will be one of system equivalence: does the accused system (an integrated watch communicating with a phone and cloud servers) perform the same steps, in the same way, as the methods claimed in the patents, which describe more discrete, multi-component architectures? The court will need to determine if there is a fundamental mismatch in technical operation or if the accused system is merely a more modern implementation of the claimed inventions.
