Case Timeline

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

U.S. Patent No. 7,246,173 - "Method And Apparatus For Classifying IP Data," issued July 17, 2007

The Invention Explained

• Problem Addressed: In packet-switched networks utilizing "source routing," where the sender specifies a path of intermediate nodes, the destination address in a packet's main header changes as it travels. This poses a problem for protocols like RSVP that classify packets to provide a certain Quality of Service (QoS), as the classification based on a temporary destination address would be incorrect and fail to match the reserved resources for the packet's true end-to-end journey (’173 Patent, col. 4:26-51).
• The Patented Solution: The invention proposes a method for classifying data packets based on information within the source routing header itself, rather than the main IP header's temporary destination address. Specifically, classification is based on the last address in the list of intermediate nodes contained in the routing header, which corresponds to the packet's final destination, ensuring consistent and correct QoS handling at each node along the path (’173 Patent, Abstract; col. 5:7-14).
• Technical Importance: This method enabled the reliable application of QoS protocols in networks employing advanced traffic engineering techniques like source routing, which were becoming more critical for managing data flows in complex IPv4 and emerging IPv6 networks (’173 Patent, col. 1:5-10).

Key Claims at a Glance

• The complaint asserts independent claim 1 (Compl. ¶27).
• Essential elements of claim 1 include:
  • A method of classifying Internet Protocol (IP) data to be sent from a source apparatus to a destination apparatus in a packet switched network.
  • Receiving said data at a first node, the data comprising a header comprising a list of at least one intermediate node to be visited on a way to the destination apparatus.
  • Classifying said data at said first node based on an entry in said header.
• The complaint does not explicitly reserve the right to assert dependent claims for this patent.

U.S. Patent No. 7,165,224 - "Image Browsing And Downloading In Mobile Networks," issued January 16, 2007

The Invention Explained

• Problem Addressed: Early mobile devices possessed very limited memory, making it impractical to store a large number of high-resolution digital images. Once images were transferred to an external storage device, such as a home computer, to free up space, they could no longer be easily browsed or viewed on the mobile device (’224 Patent, col. 1:20-28; col. 1:39-45).
• The Patented Solution: The patent describes a system where a mobile device creates and stores a "miniaturized version" (i.e., a thumbnail) of an image locally while transferring the full-sized image to an external storage device and then deleting the original from the mobile device's memory. To view the full-sized image later, the user selects the thumbnail, which triggers the mobile device to send a request message over a wireless network to the external storage; the external storage then sends the full-sized image back to the mobile device for display (’224 Patent, Abstract; col. 3:56-65).
• Technical Importance: This invention provided a practical, memory-efficient solution for managing and accessing large image collections on memory-constrained mobile devices, decoupling local browsing from remote storage (’224 Patent, col. 2:47-54).

Key Claims at a Glance

• The complaint asserts independent claim 1 (Compl. ¶44).
• Essential elements of claim 1 include:
  • A method of viewing an image on a mobile device.
  • Storing in the mobile device a miniaturized version of an image being stored in the mobile device.
  • Transferring the image to an external storage device.
  • Deleting the image from the mobile device.
  • Detecting selection of the miniaturized version of the image.
  • Sending a first message requesting transfer of the image to the mobile device via a wireless communication network in response to the selection.
  • Receiving a second message transferring the image to the mobile device via the wireless network.
• The complaint does not explicitly reserve the right to assert dependent claims for this patent.

Multi-Patent Capsule: U.S. Patent No. 7,394,798

• Patent Identification: U.S. Patent No. 7,394,798, "Push-To Talk Over Ad-Hoc Networks," issued July 1, 2008 (Compl. ¶56).
• Technology Synopsis: The patent describes a system for enabling push-to-talk (PTT) communication over ad-hoc networks. It proposes a method for network nodes to temporarily form groups and communicate directly via a radio connection, potentially with assistance from an overlay cellular network for functions like group creation, security, and routing (Compl. ¶58; ’798 Patent, Abstract).
• Asserted Claims: The complaint asserts at least independent claim 16 (Compl. ¶61).
• Accused Features: The accused functionality is the method by which Somfy's network devices form temporary groups to send and receive information via direct radio connections (Compl. ¶62).

Multi-Patent Capsule: U.S. Patent No. 7,974,266

• Patent Identification: U.S. Patent No. 7,974,266, "Method And Apparatus For Classifying Ip Data," issued July 5, 2011 (Compl. ¶73).
• Technology Synopsis: As a continuation of the '173 patent, this patent also addresses the classification of IP data in networks with source routing. The invention focuses on ensuring consistent data classification by forwarding an IP packet from a first node to a second node, where the classification at the second node is also based on the last destination address entry in the packet's header, maintaining correct QoS treatment as the packet is forwarded (Compl. ¶¶ 75, 79; ’266 Patent, Abstract).
• Asserted Claims: The complaint asserts at least independent claim 1 (Compl. ¶78).
• Accused Features: The accused functionality is the alleged method of classifying and forwarding IP data within the Somfy network, specifically between different nodes of the system (Compl. ¶79).

Multi-Patent Capsule: U.S. Patent No. 7,974,260

• Patent Identification: U.S. Patent No. 7,974,260, "Method Of Transmitting Time-Critical Scheduling Information Between Single Network Devices In A Wireless Network Using Slotted Point-To-Point Links," issued July 5, 2011 (Compl. ¶83).
• Technology Synopsis: The patent describes a method for transmitting timing control information between wireless devices. The method involves defining a data sequence with a header (containing an address code) and a payload (containing timing information) and transmitting this sequence in a defined time slot to control when the receiving device communicates (Compl. ¶85; ’260 Patent, Abstract).
• Asserted Claims: The complaint asserts at least claim 5 (Compl. ¶88).
• Accused Features: The accused functionality is the alleged method of transmitting timing and control information between devices in the Somfy system using defined data sequences and time slots (Compl. ¶89).

III. The Accused Instrumentality

Product Identification

• The complaint names the "Accused Products" as Defendant's "home security and control platform and systems," including products marketed as "Somfy Home and Security Systems" (Compl. ¶18). Specific components identified include the Somfy Connect Main Controller, IP/io Gateway, Smart Home Apps (e.g., Somfy Protect, TaHoma by Somfy), Smart Cameras, Smart Remotes, Z-Wave devices, and associated Somfy Systems Servers (Compl. ¶18).

Functionality and Market Context

• The Accused Products constitute an integrated Internet of Things (IoT) ecosystem for home automation and security. The system's functionality relies on a central controller and/or cloud servers communicating with various endpoints like cameras and sensors via multiple network protocols, including Wi-Fi, cellular, and Z-Wave (Compl. ¶18). The complaint alleges these products are advertised, sold, and operated through Defendant's website and that Defendant provides instructions for their use (Compl. ¶¶ 17, 19). For venue purposes, the complaint includes a screenshot from Defendant's website showing a "Somfy Florida Office & Showroom" located in Boynton Beach, Florida (Compl. p. 4, FIG. 1).

IV. Analysis of Infringement Allegations

’173 Patent Infringement Allegations

• Identified Points of Contention:
  • Scope Questions: A central question may be whether the communications within the Somfy smart home ecosystem, which includes proprietary devices and servers, constitute a "packet switched network" with "intermediate nodes" in the manner contemplated by the patent, which is described in the context of internet routers and RSVP protocol.
  • Technical Questions: The complaint alleges classification "based on an entry in said header" in a conclusory manner. A key technical question will be what evidence demonstrates that the Accused Products perform classification based on a specific entry in a source-routing-style header, as opposed to using other methods like standard destination IP-based routing or application-layer logic.

’224 Patent Infringement Allegations

• Identified Points of Contention:
  • Scope Questions: The court may need to determine if a "video clip" from a modern security camera falls within the scope of the term "image" as used in the patent, which primarily discusses static digital photographs.
  • Technical Questions: The "deleting the image from the mobile device" step is a specific limitation. A factual question will be whether the Accused Products perform this discrete step to free memory, as described in the patent, or if they employ a different workflow, such as directly streaming captured data to the cloud without a store-and-delete sequence on the originating device.

V. Key Claim Terms for Construction

For the ’173 Patent:

• The Term: "classifying said data ... based on an entry in said header" (from claim 1).
• Context and Importance: This term is the central inventive concept. The outcome of the infringement analysis may depend on whether "classifying... based on an entry" is limited to the specific method described in the patent (using the last address for RSVP) or can be read more broadly to cover any data handling decision that uses any information from a routing header.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The claim language itself is broad, referring simply to "an entry in said header." The summary of the invention also uses general phrasing: "classifying the data at the first node based on source routing information of the data" (’173 Patent, col. 2:49-52).
  • Evidence for a Narrower Interpretation: The detailed description repeatedly links the classification to solving a specific problem with RSVP sessions, stating the "session classification is based on the last IP address in the route data field" (’173 Patent, col. 8:65-col. 9:1). An argument could be made that the invention is limited to this specific implementation.

For the ’224 Patent:

• The Term: "deleting the image from the mobile device" (from claim 1).
• Context and Importance: This is a mandatory step in the claimed method. If the accused system does not perform this step, there can be no literal infringement. Practitioners may focus on this term because modern devices with ample storage and cloud connectivity may not follow the specific store-then-delete-to-save-space workflow of the early 2000s.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The claim does not specify when or for how long the image must be deleted. This could be argued to encompass temporary cache-clearing operations that are common in modern applications after a file is successfully uploaded.
  • Evidence for a Narrower Interpretation: The specification explicitly frames the invention as a solution to limited memory, stating, "In order to clear memory space for taking additional photographs, the user may remove some of the images from memory" (’224 Patent, col. 4:26-29). This context suggests a deliberate act of removing the primary file from persistent local storage, not just a transient cache management function.

VI. Other Allegations

• Indirect Infringement: The complaint alleges both induced and contributory infringement for the asserted patents. Inducement is alleged based on Defendant providing the Accused Products and "distributing instructions that guide users to use the Accused Products in an infringing manner" (Compl. ¶¶ 29, 46, 64). Contributory infringement is alleged on the basis that the Accused Products have "special features that are specially designed to be used in an infringing way" and are not staple articles of commerce (Compl. ¶¶ 30, 47, 65).
• Willful Infringement: Willfulness is alleged for U.S. Patent Nos. 7,246,173, 7,165,224, and 7,394,798. The allegations are based on both post-suit knowledge (Defendant "had knowledge... at least as of the date when it was notified of the filing of this action") and alleged pre-suit willful blindness ("Defendant has a policy or practice of not reviewing the patents of others") (Compl. ¶¶ 31-34, 48-51, 66-68).

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

• A central issue will be one of technical implementation: The complaint provides a high-level, functional mapping of product features to claim elements. A key evidentiary question will be whether the accused Somfy systems, in their actual operation, perform the precise, and sometimes dated, technical steps recited in the patents—such as classifying data based on the final address in a source route header ('173 patent) or performing a discrete local deletion of a full-sized file after cloud upload ('224 patent)—or if they achieve similar end-user results through different, non-infringing technical means.
• The case will also likely turn on questions of definitional scope and anachronism. Can claim terms rooted in the technological context of the early 2000s, such as "image" (referring to still photos on a flip phone) and "packet switched network" (referring to internet routers), be construed to cover modern technologies like streaming security video and proprietary IoT communication protocols within a closed smart-home ecosystem?
