II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 9,900,766 - Automatic Multimedia Upload for Publishing Data and Multimedia Content, Issued Feb. 20, 2018
The Invention Explained
- Problem Addressed: The patent describes the inconvenience for a user who captures data on a device (like a digital camera) and wants to publish it online. This typically requires a manual, multi-step process of transferring the data to a computer and then uploading it to a website, which is time-consuming. (’766 Patent, col. 1:56-col. 2:7).
- The Patented Solution: The invention provides a system where a data capture device establishes a paired wireless connection with a mobile phone. After data is captured, it is automatically transferred to an application on the phone, which then uses a cellular data network to upload the data to a "user data publishing website" for private consumption. The process is designed to be automatic or require minimal user intervention. (’766 Patent, Abstract; col. 2:20-43).
- Technical Importance: This architecture automates the workflow between disconnected peripheral devices and cloud services via a mobile hub, a key paradigm for IoT and connected health devices. (’766 Patent, col.2:8-12).

Identified Points of Contention
- Scope Questions:
- The patents frequently use the term "multimedia content" and provide examples like images and video (’766 Patent, col. 1:56-59). A potential question is whether the scope of the claims, when read in light of the specification, can be interpreted to cover the specialized, non-multimedia medical data (glucose readings) generated by the accused meters.
- The claims recite a "data capture device" and a "cellular phone." A question may arise as to whether the term "cellular phone" reads on other mobile devices like the iPad, which the complaint notes is a compatible device for the OneTouch Reveal® app. (Compl. p. 3, Figure 1).
- Technical Questions:
- The claims require specific technical functions like "cryptographically authenticating identity" (’766 Claim 1) and using a "cryptographic encryption key" (’030 Claim 12). A central question will be what evidence demonstrates that the standard Bluetooth pairing and communication protocols used by the accused system meet these specific claim limitations as defined by the patent specification.
- The claims also require specific sequences of "event notifications" and "requests" for data (’030 Claim 12). The actual communication protocol between the OneTouch meter and the Reveal® app will need to be analyzed to determine if it matches the claimed method steps or operates in a technically distinct manner.
V. Key Claim Terms for Construction
The Term: 'cryptographically authenticating identity' (’766 Patent, Claim 1) / 'cryptographic encryption key' (’030 Patent, Claim 12)
Context and Importance: These terms are central to the "secure connection" element of the inventions. The dispute will likely focus on whether the security features inherent in the standard Bluetooth protocol, which the accused system uses (Compl. p. 11, Figure 4), are sufficient to meet these limitations, or if the patent requires a non-standard or more specific security implementation. Practitioners may focus on this term because it distinguishes a mere wireless link from a specifically secured one as claimed.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The patents do not appear to define a specific cryptographic algorithm, which may support an interpretation that any standard, secure pairing process (like that in Bluetooth) which uses keys and authentication would suffice.
- Evidence for a Narrower Interpretation: The specification describes the pairing process in terms of exchanging a "common password known as a passkey" between the devices to establish a "trusted pair." (’121 Patent, col. 4:28-50). A party could argue this implies a specific type of user-involved or application-level security exchange beyond the baseline Bluetooth protocol.
The Term: 'automatically' (’766 Patent, Claim 1)
Context and Importance: This term is critical to the core value proposition of the patents—eliminating manual user steps. Infringement will depend on how "automatic" the data transfer from the meter to the app actually is. The complaint's visual evidence of "Seamlessly Sync Results" (Compl. p. 3, Figure 1) suggests a high degree of automation.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The abstract of the ’766 patent states the system works "automatically or with minimal user intervention," suggesting that the term "automatically" might not require zero user involvement (e.g., a user might need to open the app).
- Evidence for a Narrower Interpretation: The specification discusses different timer settings, including "no-wait-automatic" and "wait-X-minutes-automatic," where the latter explicitly builds in a delay for user cancellation. (’121 Patent, col. 5:58-6:11). This could be used to argue that "automatically" in the claim means the "no-wait" embodiment, requiring immediate transfer without any prompts or built-in delays.
VI. Other Allegations
- Indirect Infringement: The complaint does not contain separate counts for indirect infringement, but it alleges that Lifescan "induces others to use, the claimed methods" and that infringement occurs "jointly with its end users and/or customers." (Compl. ¶¶35, 39, 43, 47). The basis for these allegations would be Lifescan's marketing and instructional materials that direct users to operate the meters and app together in an infringing manner.
- Willful Infringement: The complaint alleges "willful encroachment" in its opening paragraphs but does not provide specific factual allegations to support a claim of pre-suit knowledge of the patents, which would be required for pre-suit willfulness. (Compl. ¶3). Post-suit willfulness is implicitly at issue upon the filing of the complaint.
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of definitional scope: Can the claims, which are described in the context of "multimedia content" like photos and videos, be construed to cover the specialized numerical data generated by the accused medical glucose monitors? The outcome will depend on whether terms like "data capture device" and "new-data" are interpreted broadly or are limited by the specification's examples.
- A second key issue will be one of technical specificity: Do the standard security and communication protocols of the accused Bluetooth-enabled system meet the precise requirements of "cryptographically authenticating identity" and the specific event-notification and request methods recited in the claims, or is there a fundamental mismatch in technical operation?
- A final determinative question will be one of degree of automation: What level of user action, if any, is permissible for a process to be considered "automatic" under the claims? The case may turn on evidence of exactly how the OneTouch meters and Reveal® app interact—whether data transfer requires the app to be open, a button to be pushed, or occurs truly in the background without user intervention.
