- Independent Claim 1 of the ’766 Patent recites the following essential elements for a short-range wireless enabled data capture device:
- A memory device and a coupled processor.
- A short-range wireless communication device to establish a paired, cryptographically authenticated wireless connection with a cellular phone using an association protocol.
- Data capture circuitry to acquire new data after the wireless connection is established.
- A processor configured to store the new data, create a "new-data object" containing the data and a notification signal, and automatically transfer this object to the phone.
- The claim further requires a mobile client application on the phone that is configured to process the notification, store the data, use HTTP to upload the data to a "user data publishing website," and use a "user identifier" for "private consumption."
U.S. Patent No. 8,904,030 - Automatic Multimedia Upload for Publishing Data and Multimedia Content
Issued December 2, 2014
The Invention Explained
- Problem Addressed: The patent identifies a need for a more efficient method than manually cabling a capture device to a PC to upload data, which it characterizes as an inconvenient, multi-step process for users wishing to share content in real-time (’030 Patent, col. 1:44-52).
- The Patented Solution: The invention discloses a method for a Bluetooth-enabled mobile device to manage data transfer from a paired Bluetooth-enabled data capture device. The method involves the mobile device detecting new data on the capture device, receiving it over the secure connection, and then transferring it to a remote internet server using methods like HTTP or RPC, along with a unique user identifier (’030 Patent, Abstract; col. 2:7-21).

Identified Points of Contention
- Scope Questions: A central dispute may arise over whether a medical device like a glucose meter, which captures numerical health readings, falls within the scope of a "data capture device" as contemplated by the patents. The specifications of the patents-in-suit heavily reference "multimedia content" such as images and video from digital cameras (’766 Patent, col. 3:52-54), which may suggest a narrower scope than what Plaintiff alleges.
- Technical Questions: Claim 1 of the ’766 Patent requires the mobile application to "upload the received new-data... to a user data publishing website." The complaint does not specify the architecture of the OneTouch backend. This raises the question of whether LifeScan's cloud service, which may be primarily for private data storage and analysis, functions as a "publishing website" in the manner required by the claim.
V. Key Claim Terms for Construction
The Term: "data capture device" (’766 Patent, Claim 1)
Context and Importance
The infringement analysis depends entirely on whether a medical device like the OneTouch glucose meter is properly classified as a "data capture device." Practitioners may focus on this term because its construction could be dispositive. Defendant will likely argue the term is limited by the specification's repeated examples, while Plaintiff will argue for a broader meaning encompassing any device that captures digital data.
Intrinsic Evidence for Interpretation
- Evidence for a Broader Interpretation: The claim language itself is broad, using the general term "data capture device" without explicitly limiting it to multimedia. The specification also mentions "text files" as an example of "multimedia content," which could support a broader reading beyond just images or video (’766 Patent, col. 3:53-54).
- Evidence for a Narrower Interpretation: The patent titles refer to "Multimedia Upload," and the detailed description consistently uses "a digital camera, a video camera, [or] digital modular camera systems" as the primary and recurring examples of the invention (’766 Patent, col. 3:63-65). This context may be used to argue the invention is confined to that domain.
The Term: "user data publishing website" (’766 Patent, Claim 1)
Context and Importance
This term is critical for the final step of the claimed process. The nature of the destination server for the transferred data will be scrutinized. The dispute will question if a private cloud backend for a health app constitutes a "publishing website."
Intrinsic Evidence for Interpretation
- Evidence for a Broader Interpretation: The claim specifies the website is used to "publish the new-data for private consumption," which could be interpreted to mean making data privately available to the user or designated third parties (e.g., a doctor), consistent with a modern cloud service model (Compl. ¶39; ’766 Patent, col. 14:8-9).
- Evidence for a Narrower Interpretation: The shared specification across the patent family provides examples of publishing destinations such as "Flickr™, Picasa™, YouTube™, eBay®" (’121 Patent, col. 9:14-16). A court may find that these examples of public or semi-public content hosting platforms limit the term "publishing website" to a similar class of service, potentially excluding a private health data repository.
VI. Other Allegations
Indirect Infringement
- The complaint alleges that Defendant induces infringement by providing "advertisements, instructions" and user manuals that encourage and direct end-users to operate the OneTouch meters and Reveal app together in the allegedly infringing manner (Compl. ¶40, ¶48). It also alleges joint infringement with end users (Compl. ¶40).
Willful Infringement
- The willfulness allegation is based on Defendant's alleged knowledge of the patents-in-suit "from at least the time of the filing of the original complaint in April 2024" (Compl. ¶40, ¶48, ¶55). The claim is therefore based on alleged post-suit continuation of infringing activities.
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of definitional scope: can the term "data capture device", rooted in a specification focused on "multimedia content" from cameras, be construed broadly enough to cover a medical instrument like a glucose meter that captures numerical health data?
- A key evidentiary question will be one of technical implementation: does the accused OneTouch system's backend architecture, which receives synced glucose data, meet the specific claim requirement of a "user data publishing website," or is there a functional mismatch between a private health data cloud and the "publishing" platforms exemplified in the patent?
- A final question will center on joint and indirect infringement: given that the system requires actions by both the Defendant (providing the system) and the end-user (operating it), the case may turn on whether Plaintiff can sufficiently prove that Defendant's instructions and the design of its system actively induce users to perform the specific steps of the patented methods.
