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

U.S. Patent No. 7,567,541 - "System and Method for Personal Data Backup for Mobile Customer Premises Equipment"

• Issued: July 28, 2009

The Invention Explained

• Problem Addressed: At the time of the invention, backing up personal data from mobile devices was described as burdensome. Existing methods involved either manual re-entry of data, which was time-consuming and error-prone, or the use of specialized physical cradles, which were not widely available, required the user and device to be in the same location, and often needed a technician's assistance. These limitations created a risk of irreparable data loss if a device was lost, damaged, or replaced. (Compl. ¶21; ’541 Patent, col. 1:24-56).
• The Patented Solution: The patent describes a system where data on a mobile device ("customer premises equipment" or "CPE") is automatically formatted, associated with a user ID, and transmitted over a mobile network to a remote server for storage. This stored data can then be retrieved and restored to a mobile device upon request or at a scheduled time, solving the problem of physical tethers and manual data transfer. The detailed description explains a communication flow where the CPE and server exchange signals to initiate and manage the backup and restoration process. (’541 Patent, Abstract; col. 2:1-32).
• Technical Importance: The invention proposed a flexible, remote backup system that could work across different devices, makes, and models, a significant improvement over device-specific and location-dependent solutions. (Compl. ¶22; ’541 Patent, col. 1:56-59).

Key Claims at a Glance

• The complaint asserts independent claims 1, 11, 17, and 21, and reserves the right to assert dependent claims. (Compl. ¶23).
• Independent Claim 1 (Method):
  • storing data at the mobile customer premises equipment;
  • formatting the data into fields by determining data fields, identifying which portions of the data correspond to a respective data field, and tagging the data;
  • transmitting the data with a user ID from the mobile CPE across a mobile network to a server for storage;
  • retrieving the data from the server in response to an expiration of time or a request; and
  • transmitting the retrieved data to the mobile CPE by transmitting it in more than one information signal and sequentially numbering each signal.
• Independent Claim 11 (Method):
  • formatting data at the mobile CPE into fields;
  • transmitting only the changes in data since a previous transmission with a user ID to a server for storage;
  • transmitting the data in more than one sequentially numbered information signal;
  • doing so in response to an expiration of time, a request from the server, or a change in data status at the mobile CPE; and
  • the server storing the data for retrieval and transmitting it back to the mobile CPE.
• Independent Claim 17 (System):
  • a mobile CPE that stores data, formats it into fields, and selectively sends a request for the data; and
  • a server that communicates with the mobile CPE over a mobile network, stores the data, and retrieves the data for transmission back to the CPE, where the server itself performs the steps of determining data fields, identifying data portions, and tagging data.
• Independent Claim 21 (System):
  • a mobile CPE that stores data, formats it into fields, and selectively transmits the data with a user ID; and
  • a server that communicates with the mobile CPE, stores the data for retrieval, and stores the data in response to its transmission from the mobile CPE, with the mobile CPE transmitting only data changes since a previous transmission.

III. The Accused Instrumentality

Product Identification

The Synchronoss Personal Cloud product and service. (Compl. ¶18).

Functionality and Market Context

• The complaint describes the Synchronoss Personal Cloud as a "white-label solution" provided to mobile network operators like Verizon for syncing, backing up, and uploading user data from mobile phones. (Compl. ¶¶16, 32).
• The accused functionality includes backing up various data types such as contacts, photos, videos, music, documents, messages, and call history. (Compl. ¶32). The service is accessible through a mobile application, a desktop application, or a web browser. (Compl. ¶31). A screenshot in the complaint shows a settings menu where users can select which categories of data to back up. This screenshot illustrates the accused product's feature of categorizing different types of user data for backup. (Compl. p. 10).

IV. Analysis of Infringement Allegations

The complaint provides a detailed infringement theory for Claim 1 of the ’541 Patent.

'541 Patent Infringement Allegations

Claim Element (from Independent Claim 1)	Alleged Infringing Functionality	Complaint Citation	Patent Citation
storing data at the mobile customer premises equipment;	The Synchronoss Personal Cloud mobile application allows for syncing, backing up, and uploading of data (e.g., contacts, photos) stored on the user's mobile device.	¶34	col. 3:5-14
formatting the data stored at the mobile customer premises equipment into fields by determining data fields, identifying which portions of said data correspond to a respective data field, and tagging said data;	The product allegedly "formats the data... into fields" by categorizing uploaded data stored on the phone. Data fields are said to include contacts, photographs, videos, music, and call history.	¶¶35, 36	col. 4:10-14
transmitting the data with a user ID from the mobile customer premises equipment across a mobile network to a server for storage;	The product allegedly requires a user phone number or user ID to access the service, and this identifier is transmitted with the data to Synchronoss servers. A screenshot shows a "Sign in" screen requiring a "User ID or Mobile Number."	¶¶37, 38; p. 11	col. 3:24-27
retrieving said data from said server across a mobile network in response to one of an expiration of time and request from said mobile customer premises equipment;	The product allows a user to request and download data (e.g., contacts, photos) to a mobile phone from the server. A screenshot of a "Content Restore" function is provided as evidence.	¶39; p. 12	col. 5:21-34
by transmitting the data to said mobile customer premises equipment by transmitting the data in more than one information signal and sequentially numbering each of said information signals.	The complaint alleges that the product uses sequentially-numbered TCP/IP packets to transmit data between mobile phones and its servers, which allegedly constitutes transmitting sequentially-numbered information signals.	¶40	col. 4:48-55

• Identified Points of Contention:
  • Scope Questions: The complaint's theory for the "formatting...and tagging" limitation relies on the product's categorization of data into types like "Contacts" and "Photos." A potential point of contention is whether this high-level categorization meets the more specific claim requirements of "determining data fields, identifying which portions of said data correspond to a respective data field, and tagging said data," which could be construed to require a more granular, structured data format like XML as discussed in the patent's specification.
  • Technical Questions: The complaint alleges that the use of standard, sequentially-numbered TCP/IP packets satisfies the claim element of "transmitting the data in more than one information signal and sequentially numbering each of said information signals." A key technical question is whether this limitation is met by simply using a standard transport protocol or if it requires a distinct, application-layer sequential numbering scheme as contemplated by the patent.

V. Key Claim Terms for Construction

• The Term: "formatting the data...into fields by determining data fields, identifying which portions of said data correspond to a respective data field, and tagging said data"

• Context and Importance: This term is central to defining what level of data manipulation is required on the mobile device before transmission. The construction will determine whether simply separating data by category (e.g., photos vs. contacts) is sufficient for infringement, or if a more complex, structured data-tagging process is required.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The specification describes the data to be backed up in broad categories, such as "telephone numbers, addresses, a calendar or schedule, a diary...personalized ring tones, displays, photos, music," which may support an interpretation that handling these distinct types of data is the "formatting" claimed. (’541 Patent, col. 3:6-12).
  • Evidence for a Narrower Interpretation: The specification suggests a more technical process, stating the format "may identify each element type by using unique tags for the different record types" and that "XML, html or other methods...may be used to create the structured data." (’541 Patent, col. 3:19-21, col. 4:12-14). This language could support a narrower construction requiring a specific markup or tagging implementation.

• The Term: "transmitting the data in more than one information signal and sequentially numbering each of said information signals"

• Context and Importance: This limitation appears in multiple independent claims and is critical to the data transmission step. The dispute may turn on whether an "information signal" is synonymous with a packet from a standard protocol like TCP/IP.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The patent states that communication can occur via "internet protocol connection." (’541 Patent, col. 3:52-53). Since TCP/IP is the foundational protocol for internet connections and inherently uses sequentially numbered packets, this could support the view that its use satisfies the claim.
  • Evidence for a Narrower Interpretation: The patent describes a specific communication flow and notes that "each signal or each packet is provided with a sequential number as well as an acknowledgement of the received update request signal." (’541 Patent, col. 4:26-29). This could be interpreted to require an application-specific numbering scheme that is distinct from the underlying transport protocol's sequencing, potentially creating a higher bar for infringement.

VI. Other Allegations

• Indirect Infringement: The complaint alleges inducement to infringe, stating that Synchronoss configures its Personal Cloud to operate in an infringing manner and encourages its customers (e.g., Verizon) and end-users to use the product in a way that directly infringes the ’541 Patent. (Compl. ¶49). It also alleges contributory infringement, asserting the Personal Cloud is especially made for infringement and is not a staple article of commerce suitable for substantial non-infringing use. (Compl. ¶50).
• Willful Infringement: Willfulness is alleged based on Synchronoss having knowledge of the ’541 Patent since at least June 20, 2018. The complaint further alleges that Synchronoss investigated Dropbox’s intellectual property during prior litigation between the companies, and that Synchronoss failed to conduct an investigation or take remedial action after learning of the ’541 Patent. (Compl. ¶¶ 41-47).

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

• A core issue will be one of definitional scope: can the claim term "formatting... and tagging," which the patent specification links to structured formats like XML, be construed broadly enough to cover the high-level categorization of data types (e.g., "Photos," "Contacts") performed by the accused cloud backup service?
• A key evidentiary question will concern functional operation: does the accused product's use of standard TCP/IP for data transport, which inherently involves sequentially numbered packets, satisfy the claim limitation of "sequentially numbering each of said information signals," or does the patent require a distinct, application-level numbering system for the backup process itself?
• The willfulness claim will likely depend on factual discovery regarding when Synchronoss first became aware of the ’541 Patent and what, if any, actions it took in response, particularly in light of the prior litigation history between Synchronoss and Plaintiff's parent company, Dropbox.
